I’ve made mashed potatoes more times than I can count, but when I started roasting the garlic first, everything changed. The transformation is undeniable — buttery, caramelized garlic weaves itself through the creamy potatoes, taking something ordinary and making it truly spectacular.

It’s rustic, soul-warming, and quietly sophisticated.

Let’s just say they don’t last long. It’s a dish that never fails to please everyone at the table, and once you taste it, you’ll understand why.

Why You’ll Love This Roasted Garlic Mashed Potatoes Recipe

This recipe isn’t just another mashed potato dish. The slow-roasted garlic adds a mellow sweetness and rich umami flavor that elevates the entire experience. The potatoes are whipped to smooth, cloud-like perfection with a hint of butter and cream, and every bite is infused with golden, roasted garlic goodness. Whether you’re looking for a new holiday favorite or a reliable side that never disappoints, these mashed potatoes will earn a permanent spot in your recipe rotation.

Ingredients

Russet potatoes: These are ideal for mashing due to their high starch content. They become fluffy and absorb butter and cream perfectly.

Garlic bulbs: Roasting whole garlic bulbs until golden transforms their sharp bite into a deep, sweet, mellow flavor. It’s the signature note in this recipe.

Butter: Unsalted is best, giving you control over the salt level. It adds creaminess and enhances every bite.

Heavy cream: This brings rich, smooth texture and helps balance the garlic’s earthiness with a luxurious mouthfeel.

Salt: To enhance the natural flavors of the potatoes and garlic.

Black pepper: Just a pinch adds warmth and complexity.

How to Make Roasted Garlic Mashed Potatoes

Step 1: Roast the Garlic

Start by preheating your oven to 400°F (200°C). Slice the tops off two whole garlic bulbs to expose the cloves. Drizzle with olive oil, wrap in foil, and roast for 35 to 40 minutes until the cloves are golden, soft, and fragrant.

Step 2: Cook the Potatoes

While the garlic is roasting, peel and chop about 3 pounds of russet potatoes into chunks. Boil them in salted water for 15 to 20 minutes until fork-tender. Drain well.

Step 3: Mash and Mix

Squeeze the roasted garlic cloves out of their skins and mash them slightly. In a large pot or mixing bowl, combine the drained potatoes with the garlic, 1/2 cup of unsalted butter, and 1/2 cup of heavy cream. Mash until smooth and creamy. Adjust the texture with more cream if needed.

Step 4: Season and Serve

Taste the mixture and season with salt and black pepper to your liking. Serve hot, optionally garnished with a pat of butter or chopped chives for a little color and freshness.

Recipe Variations and Possible Substitutions

If you want to put a twist on the classic Roasted Garlic Mashed Potatoes, try swapping in Yukon Gold potatoes for a creamier, buttery texture. They’re naturally rich and make the mash feel even more decadent. For a dairy-free option, replace the butter with olive oil and the cream with warm almond or oat milk — it’s still luscious, just lighter.

Feeling indulgent? Stir in some cream cheese or sour cream to add an extra tangy richness. And if you love herbs, try mixing in freshly chopped rosemary or thyme for an earthy aroma that pairs beautifully with the garlic.

Serving and Pairing Suggestions

Roasted Garlic Mashed Potatoes are incredibly versatile. I love them alongside a hearty meatloaf, roast beef, or a perfectly cooked steak. They also make a great base for a saucy dish like chicken marsala or mushroom gravy. For a vegetarian pairing, top with sautéed mushrooms and caramelized onions.

To elevate them even more, serve in a warm bowl with a drizzle of garlic-infused olive oil or a sprinkle of crispy fried shallots on top. The crunch against the creamy mash is out of this world.

Storage and Reheating Tips

If you have leftovers (lucky you!), store them in an airtight container in the refrigerator for up to 3 days. To reheat, place them in a saucepan over low heat, adding a splash of milk or cream to loosen them up as they warm. You can also microwave them in short bursts, stirring in between.

They freeze surprisingly well too. Portion them into airtight containers or freezer bags and store for up to a month. Thaw in the refrigerator overnight before reheating gently on the stove.

Yes! These mashed potatoes can be made a day in advance. Just store them covered in the fridge and reheat gently on the stove with a bit of cream or butter.
