Roasted garlic mashed potatoes are rich, creamy, and packed with flavor. This version replaces bland, plain mash with the caramelized sweetness of a whole roasted garlic bulb, sea salt, plenty of butter, a splash of heavy cream, and fresh thyme for a subtle herb finish. It’s an easy side that feels special enough for holidays yet simple enough for weeknight dinners.
These mashed potatoes pair perfectly with roasted meats and roasted or steamed vegetables. They reheat well, so they’re a great make-ahead side for holiday meals or any time you want comforting, flavorful potatoes.
How To Make Roasted Garlic Mashed Potatoes
Ingredients
- 1 whole garlic bulb (roasted)
- Extra virgin olive oil for drizzling
- Sea salt and freshly ground black pepper, to taste
- 1.5 lbs russet or Yukon Gold potatoes, peeled and cut into large chunks
- 1 stick (about 4 tablespoons) unsalted butter, softened, plus 1 tablespoon for garnish
- 1/4 cup heavy cream (add more if you prefer looser potatoes)
- Fresh thyme for garnish
Instructions
Roast the garlic:
- Preheat the oven to 350°F (175°C).
- Slice about 1/4 inch from the top of the garlic bulb to expose the tops of the cloves. Set the bulb cut-side up on a sheet of aluminum foil.
- Drizzle with olive oil, sprinkle with sea salt, wrap the bulb in the foil, and roast for 40–60 minutes, until the cloves are soft and deeply golden. Allow to cool slightly, then squeeze or press the cloves out of their skins and mash into a paste. Set aside.
Cook the potatoes:
- Peel the potatoes, rinse to remove any dirt, and cut into large, even pieces.
- Place the potatoes in a large pot and cover with cold water. Add a generous pinch of salt to the water.
- Bring to a boil over high heat, then reduce to a simmer and cook until the potatoes are fork-tender, about 15–20 minutes depending on size.
- Drain well in a colander and return the potatoes to the hot pot to let excess moisture evaporate briefly.
Mash and finish:
- Add the roasted garlic paste, softened butter, heavy cream, salt, and pepper to the hot potatoes.
- Use a hand masher to mash until smooth and creamy. Avoid electric mixers or high-speed tools to prevent a gluey texture.
- Taste and adjust seasoning. Add a little more cream or butter if you prefer a richer, looser mash.
- Transfer to a serving bowl, top with the extra tablespoon of butter and scatter fresh thyme leaves over the top.
What To Serve With Roasted Garlic Mashed Potatoes
- Main courses: Roasted or herb-butter turkey, roasted turkey breast or legs, pork tenderloin, roasted chicken, or seasoned meatballs. These potatoes complement both elegant holiday mains and simple weeknight proteins.
- Gravy: Brown gravy, pan sauce, or a white gravy are all excellent over these mashed potatoes.
- Vegetables: Pair with roasted Brussels sprouts, garlic-parmesan cauliflower, glazed carrots, or a green salad to balance the richness.
Tips and Notes
- Start potatoes in cold water so they cook evenly; adding them to already boiling water can yield uneven results.
- Make sure potatoes are very tender before mashing to avoid lumps.
- Use a hand masher for the best texture. Overworking with electric beaters or blenders can make potatoes gummy.
- Adjust cream and butter to taste — use less for a firmer mash, more for a silkier finish.
- To store: Keep cooled leftovers in an airtight container in the refrigerator for 3–5 days.
- To freeze: Place cooled mashed potatoes in a freezer-safe container or bag for up to one month. Thaw in the refrigerator before reheating.
- To reheat: Warm gently in a pot over low heat, stirring and adding a splash of cream or milk as needed, or reheat in the microwave in short increments, stirring between intervals.
