Red Garlic Mashed Potatoes

Red Garlic Mashed Potatoes (Creamy Roasted Garlic Mashed Red Potatoes)

These Red Garlic Mashed Potatoes are creamy, buttery, and packed with delicious roasted garlic flavor! Made with tender red skin potatoes, a whole head of roasted garlic, melted butter, and rich half-and-half, this easy side dish is the perfect addition to everything from weeknight dinners to holiday meals.

And let me tell you, roasting the garlic makes all the difference.

Instead of that sharp, pungent flavor you get from raw garlic, roasting transforms the cloves into something soft, mellow, and slightly sweet. When you mash them into warm red potatoes with butter and cream, you get the most delicious garlic flavor without it being overpowering.

The best part? You don’t even have to peel the potatoes!

Red potatoes have thin, tender skins that add a wonderful texture and a little color to the finished dish.

I love leaving a few small lumps in my mashed potatoes, especially when I’m using red potatoes. They give you that homemade, rustic texture while still being creamy and rich.

Whether you’re serving these alongside a juicy steak, roasted chicken, pork chops, or your Thanksgiving turkey, these roasted garlic mashed potatoes are the kind of side dish everyone reaches for.

Why You’ll Love These Red Garlic Mashed Potatoes

There’s nothing quite like a bowl of homemade mashed potatoes, especially when they’re loaded with buttery roasted garlic.

Here’s why this recipe is one of my favorite ways to prepare red potatoes:

• Real roasted garlic flavor: A whole head of garlic adds a rich, mellow flavor that’s so much better than using garlic powder alone.
• No peeling required: The thin skins on red potatoes are tender enough to leave on.
• Creamy and buttery: Six tablespoons of butter and half-and-half give these potatoes a wonderfully rich texture.
• Simple ingredients: You only need a handful of everyday ingredients.
• Easy to customize: Add Parmesan cheese, fresh herbs, or a little sour cream if you want to change things up.
• Perfect for any occasion: These potatoes are delicious with weeknight dinners but special enough for holidays.
• Great texture: They’re creamy without needing to be completely smooth.

And if you love garlic as much as I do, you’re going to appreciate how much flavor that roasted garlic adds.

What Are Red Garlic Mashed Potatoes?

Red garlic mashed potatoes are a variation of traditional mashed potatoes made with red skin potatoes and garlic.

For this recipe, we’re using roasted garlic instead of raw or sautéed garlic.

That gives the potatoes a deeper, sweeter, more mellow garlic flavor.

We’re also leaving the potato skins on, which creates a rustic texture.

Unlike the very smooth mashed potatoes you might make with peeled russet potatoes, mashed red potatoes tend to be slightly denser and creamier, with tender pieces of skin throughout.

They’re especially delicious when you want a comforting, steakhouse-style side dish without a lot of complicated prep work.

Ingredients You’ll Need

You only need a few simple ingredients to make these creamy roasted garlic mashed red potatoes.

Red Potatoes — 2 Pounds

Red potatoes are the star of this recipe.

Their thin skins mean you don’t have to peel them, and their naturally creamy texture makes them wonderful for rustic mashed potatoes.

Wash the potatoes thoroughly and cut them into quarters before boiling.

Try to keep the pieces similar in size so they cook evenly.

Garlic — 1 Whole Head

Yes, we’re using an entire head of garlic!

Don’t worry. Roasted garlic is much milder than raw garlic.

After about an hour in the oven, the cloves become soft, sweet, and easy to mash directly into the potatoes.

Olive Oil — 1 Teaspoon

A little olive oil helps the garlic roast without drying out.

Kosher Salt — 1 Teaspoon for Boiling

Salting the cooking water seasons the potatoes as they cook.

You’ll also want to taste the finished mashed potatoes and add more salt if needed.

Unsalted Butter — 6 Tablespoons

Butter adds richness and helps create that creamy, comforting texture.

I prefer unsalted butter because it gives me more control over the seasoning.

Half-and-Half — ¾ Cup

Half-and-half gives the potatoes a rich, creamy consistency without being quite as heavy as using all heavy cream.

Warming it with the butter before adding it to the potatoes helps everything blend together more easily.

Freshly Ground Black Pepper — To Taste

Black pepper adds a little warmth and balances the richness of the butter and cream.

Optional Garnishes

For serving, you can add:

• Chopped fresh parsley
• Fresh chives
• An extra pat of butter
• Additional freshly ground black pepper

I especially love finishing mashed potatoes with a little extra melted butter and fresh chives.

How to Make Red Garlic Mashed Potatoes

This recipe is simple, but there are a few techniques that make a big difference in the finished texture.

Step 1: Roast the Garlic

Preheat your oven to 375°F.

Take one whole head of garlic and slice approximately ¼ inch off the top, exposing the cloves.

Place the garlic on a piece of aluminum foil.

Drizzle with 1 teaspoon olive oil, then wrap the foil tightly around the garlic.

Place it on a small baking sheet and roast for approximately 1 hour, or until the cloves are soft and golden.

Once the garlic is cool enough to handle, gently squeeze the roasted cloves out of their skins.

Set them aside.

Step 2: Prepare the Red Potatoes

Wash 2 pounds of red potatoes thoroughly.

Cut them into quarters, keeping the pieces as uniform as possible.

There’s no need to peel them!

The thin red skins add texture and make this recipe even easier.

Step 3: Boil the Potatoes

Place the quartered potatoes into a large pot or Dutch oven.

Add enough cold water to cover the potatoes.

Stir in 1 teaspoon kosher salt.

Bring the water to a boil, then reduce the heat and simmer for approximately 15 minutes, or until the potatoes are fork-tender.

Larger pieces may need closer to 20 minutes.

You should be able to easily pierce the potatoes with a fork without resistance.

Step 4: Drain the Potatoes

Carefully drain the cooked potatoes.

Allow any excess moisture to evaporate for a minute or two.

This is important because too much water can make mashed potatoes thin or watery.

Return the potatoes to the warm pot.

Step 5: Warm the Butter and Half-and-Half

In a small saucepan over low heat, combine:

• 6 tablespoons unsalted butter
• ¾ cup half-and-half

Warm gently until the butter melts.

You don’t need to bring the mixture to a boil.

You can also heat the ingredients together in a microwave-safe bowl.

Step 6: Mash the Potatoes

Add the roasted garlic cloves to the drained potatoes.

Pour in the warm butter and half-and-half mixture.

Using a potato masher, gently mash everything together until the potatoes reach your desired consistency.

I like mine creamy with a few small lumps and pieces of red potato skin throughout.

Avoid overmixing, which can make the potatoes gummy.

Step 7: Season to Taste

Add freshly ground black pepper and additional salt as needed.

Taste before serving.

Potatoes need enough seasoning to bring out all that delicious buttery garlic flavor.

Step 8: Serve Warm

Transfer the mashed potatoes to a serving bowl.

Top with an extra pat of butter and sprinkle with fresh parsley or chives, if desired.

Serve immediately while warm.

Why Roast the Garlic Instead of Using Raw Garlic?

Roasting garlic changes both its flavor and texture.

Raw garlic has a sharp, strong flavor that can easily overpower mashed potatoes.

When you roast an entire head of garlic, the cloves become soft, creamy, and slightly sweet.

That mellow garlic flavor blends beautifully with the potatoes and butter.

It also makes the garlic incredibly easy to incorporate.

You can simply squeeze the softened cloves directly into the potatoes and mash everything together.

For me, that extra roasting time is absolutely worth it.

Why Red Potatoes Are Great for Mashed Potatoes

Red potatoes are considered waxy potatoes, meaning they generally have less starch than russet potatoes.

That gives them a naturally creamy, slightly dense texture.

They’re especially good for mashed potatoes when you want a rustic finish instead of an ultra-light, whipped consistency.

Another reason I love them is their thin skin.

Unlike thicker-skinned potatoes, red potatoes can be mashed with the skins still on.

That saves prep time and adds a little texture to every bite.

Should You Peel Red Potatoes Before Mashing?

No, you don’t have to!

For this recipe, I recommend leaving the skins on.

The thin skins soften as the potatoes cook and blend into the finished mashed potatoes.

They add color, texture, and that homemade appearance I love.

However, if you prefer completely smooth mashed potatoes, you can peel them before boiling.

It’s entirely up to you.

How to Make Creamy Mashed Red Potatoes

Getting creamy mashed potatoes isn’t difficult, but a few simple techniques can make a big difference.

Start With Cold Water

Always place the potatoes in cold water before bringing them to a boil.

This helps them cook more evenly.

If you drop potatoes directly into boiling water, the outside can soften before the center finishes cooking.

Cook Until Fork-Tender

Undercooked potatoes won’t mash smoothly.

Make sure a fork slides easily through the center of the potato pieces.

Drain Thoroughly

Excess cooking water can make mashed potatoes watery.

Drain them well before adding the butter and cream.

Warm the Dairy

Adding warm butter and half-and-half helps the ingredients blend into the potatoes.

It also prevents the cold dairy from cooling everything down too quickly.

Don’t Overmix

This is especially important with red potatoes.

Too much mixing can release excess starch and create a gluey texture.

Use a potato masher and stop once you’ve reached the consistency you like.

Why Are My Mashed Potatoes Gummy?

Gummy mashed potatoes are usually caused by overworking the potatoes.

When potatoes are mashed too aggressively, their starch can make the mixture sticky.

This is particularly noticeable with waxy varieties like red potatoes.

For the best results, use a handheld potato masher rather than a blender or food processor.

Mash gently and stop once everything is combined.

A few small lumps are perfectly fine.

Can I Use Heavy Cream Instead of Half-and-Half?

Absolutely.

Heavy cream will make the potatoes richer and thicker.

You can replace the half-and-half with heavy cream if you prefer a more indulgent texture.

You may need to adjust the amount slightly depending on how thick you like your mashed potatoes.

For the original recipe, I think half-and-half provides a wonderful balance of richness and creaminess.

Can I Use Whole Milk?

Yes.

Whole milk is a good alternative if you don’t have half-and-half.

The finished potatoes won’t be quite as rich, but they’ll still be delicious.

You can also add a little extra butter if you want more richness.

Can I Add Sour Cream?

Yes!

Sour cream adds a tangy flavor that pairs beautifully with roasted garlic.

If you want to make a variation, stir in a few tablespoons of sour cream after mashing.

Because sour cream adds moisture, you may want to start with slightly less half-and-half.

Can I Add Parmesan Cheese?

Absolutely.

Freshly grated Parmesan cheese is delicious in garlic mashed potatoes.

It adds a salty, savory flavor that complements the roasted garlic.

If you’re adding Parmesan, taste the potatoes before adding extra salt because the cheese is already salty.

Can I Use Garlic Powder Instead of Roasted Garlic?

You can use garlic powder in a pinch, but the flavor won’t be quite the same.

Roasted garlic has a mellow sweetness and creamy texture that garlic powder doesn’t provide.

If you’re short on time, garlic powder can still add flavor, but I recommend trying the roasted garlic version at least once.

It’s what makes these potatoes special.

Can I Use Baby Red Potatoes?

Yes.

Baby red potatoes work beautifully in this recipe.

Depending on their size, you may only need to halve them rather than cut them into quarters.

The important thing is to keep the pieces relatively uniform so they cook evenly.

What to Serve With Red Garlic Mashed Potatoes

These creamy garlic mashed potatoes are one of those side dishes that go with almost anything.

Some of my favorite pairings include:

• Roasted chicken
• Garlic butter steak
• Pork chops
• Meatloaf
• Pot roast
• Roast turkey
• Beef tips and gravy
• Baked chicken thighs
• Roasted vegetables
• Green beans

They’re especially good with dishes that have gravy or a savory pan sauce.

I love spooning a little extra gravy over the potatoes and letting it settle into all those delicious buttery crevices.

Perfect for Holidays and Special Occasions

Mashed potatoes are one of those dishes that always seem to have a place on the holiday table.

Whether it’s Thanksgiving, Christmas, Easter, or a family Sunday dinner, they’re a classic side dish everyone recognizes.

These roasted garlic mashed red potatoes are a wonderful alternative to traditional mashed potatoes.

The roasted garlic gives them a little something extra without making the recipe complicated.

And because you can roast the garlic ahead of time, they’re easier to prepare when you’re cooking several dishes at once.

Can I Roast the Garlic Ahead of Time?

Yes!

Roasting the garlic ahead is one of my favorite ways to make this recipe more convenient.

You can roast the garlic a day or two before preparing the potatoes.

Once cooled, remove the cloves from their skins and store them in an airtight container in the refrigerator.

Don’t leave roasted garlic stored in oil at room temperature.

When you’re ready to make the mashed potatoes, simply add the roasted cloves during the mashing step.

Can I Make Garlic Mashed Potatoes Ahead of Time?

Yes.

You can prepare the mashed potatoes ahead and refrigerate them until you’re ready to serve.

Keep in mind that mashed potatoes tend to thicken as they cool.

When reheating, add a small splash of milk or half-and-half to bring back their creamy consistency.

I recommend reheating gently over low heat and stirring occasionally.

How to Store Leftover Garlic Mashed Potatoes

Allow the mashed potatoes to cool slightly, then transfer them to an airtight container.

Refrigerate promptly and store for approximately 3–4 days.

Because the recipe contains butter and half-and-half, don’t leave the potatoes sitting at room temperature for extended periods.

How to Reheat Red Garlic Mashed Potatoes

My favorite way to reheat mashed potatoes is on the stovetop.

Place them in a saucepan over low heat.

Add a splash of milk or half-and-half and a small pat of butter.

Stir gently until the potatoes are heated through.

You can also reheat them in the microwave using a microwave-safe container.

Heat in short intervals, stirring between each one.

For food safety, reheat leftovers to 165°F.

Can You Freeze Garlic Mashed Potatoes?

Yes.

Because these mashed potatoes contain butter and half-and-half, they generally freeze better than mashed potatoes made without much fat.

Allow them to cool completely, then transfer to freezer-safe containers.

Freeze for approximately 1–2 months for the best texture.

Thaw in the refrigerator overnight before reheating.

You may need to add a little milk or cream to restore their consistency.
