Mashed potatoes are a must-have comfort food, but when you add roasted garlic into the mix, they become something extra special. These garlic mashed potatoes are creamy, rich, and full of mellow garlic flavor that doesn’t overpower. They’re perfect for everything from weeknight dinners to holiday spreads and are always the first side dish to disappear.
This recipe combines simple ingredients with a little extra technique to create mashed potatoes that feel like a treat without going over the top. Once you start making them this way, plain mashed potatoes just won’t cut it.
Ingredients
- 2 lbs Yukon Gold or Russet potatoes, peeled and cut into chunks
- 1 head of garlic
- 4 tablespoons butter (plus more to taste)
- 1/2 cup whole milk or cream (warmed)
- 1/4 cup sour cream (optional, for extra creaminess)
- Salt and black pepper to taste
- Chopped chives or parsley for garnish (optional)
- Olive oil for roasting garlic
Why Roasted Garlic Makes a Difference
Roasted garlic brings out a mellow, slightly sweet flavor that blends seamlessly into creamy mashed potatoes. Raw garlic can be too pungent or sharp, but roasting it softens all of that into a deep, rich background note that enhances without overwhelming.
Step 1: Roast the Garlic
Start by roasting your garlic. Preheat the oven to 400°F (200°C). Slice the top off the head of garlic to expose the cloves, drizzle with olive oil, wrap in foil, and roast for 35–40 minutes until the cloves are soft, golden, and caramelized.
Once cool enough to handle, squeeze the roasted garlic out of the skins into a small bowl. It should be soft and spreadable.
Step 2: Boil the Potatoes
While the garlic is roasting, place the peeled and chopped potatoes into a large pot and cover them with cold, salted water. Starting them in cold water ensures they cook evenly and don’t turn mushy on the outside before the inside softens.
Bring the pot to a boil, then reduce the heat to a gentle simmer. Cook for 15–20 minutes or until the potatoes are fork-tender. Drain them well and let them sit for a minute to steam dry—this step removes excess moisture that can water down the mash.
Step 3: Mash and Mix
Return the hot potatoes to the pot or transfer them to a large mixing bowl. Add the roasted garlic, butter, and warm milk or cream. Mash with a potato masher or use a hand mixer on low speed until smooth and fluffy.
Add the sour cream if you want extra richness and tang. Season with salt and black pepper. Taste and adjust until it hits just right—don’t be afraid to add more butter if that’s your vibe.
Creamy Potato Pro Tips
- Warm your dairy. Cold milk or cream can shock the potatoes and make them gluey. Warm dairy blends in smoothly and keeps the mash fluffy.
- Use the right potato. Yukon Golds give the mash a naturally buttery texture and color. Russets are starchier and fluffier. A mix of both is even better.
- Avoid over-mashing. Overworking the potatoes can make them gummy. Mash just until smooth and no more.
Customize It to Your Taste
These mashed potatoes are easy to customize based on what you like or have on hand. Here are some ideas:
- For extra richness: Stir in cream cheese, goat cheese, or mascarpone.
- For a tangy punch: Add a splash of buttermilk or plain Greek yogurt.
- For bold flavor: Mix in grated Parmesan or cheddar cheese.
- For herby vibes: Fold in fresh thyme, rosemary, or finely chopped chives.
Want to make them dairy-free or vegan? Swap in plant-based butter and unsweetened almond or oat milk. Use roasted garlic oil instead of butter for added depth.
What to Serve With Garlic Mashed Potatoes
These mashed potatoes go with just about anything. Some great pairings include:
- Roast chicken or turkey
- Grilled or pan-seared steak
- Meatloaf or veggie loaf
- Mushroom or brown gravy
- Roasted vegetables like carrots, Brussels sprouts, or green beans
- Vegetarian stews or lentil dishes
They also shine as part of a holiday spread, especially with gravy or cranberry sauce nearby.
Making Ahead and Storing
Garlic mashed potatoes can be made ahead and stored in the fridge for up to 4 days. Reheat gently in a saucepan over low heat with a splash of milk or broth to loosen them up. Stir often to prevent sticking.
If you want to freeze them, portion them into airtight containers. Reheat in the microwave or stovetop and stir in more butter or milk to bring back the texture.
Leftover Ideas

- Potato pancakes or fritters
