Ingredients

• Yukon gold potatoes: These naturally buttery potatoes create a smooth, creamy mash while holding enough structure to stay fluffy.
• Garlic cloves: Garlic adds mellow savory flavor after gently steeping in the warm cream.
• Fresh rosemary: Rosemary brings a fragrant, woodsy note; thyme or sage can be used instead.
• Unsalted butter: Butter adds richness and a glossy finish, while unsalted butter gives you better control over seasoning.
• Heavy cream: Warm cream loosens the potatoes and makes the texture luxurious; whole milk works for a lighter version.

1. Boil the potatoes:

Place the cubed potatoes in a large pot, cover them with cold water, add the cooking salt, and simmer until fork tender, about 15–20 minutes.

2. Warm the cream:

Heat the cream and softened butter in a small saucepan over medium heat until the butter melts and the mixture is warm.

3. Infuse the flavors:

Add the garlic cloves and rosemary sprigs to the warm cream, steep for 10 minutes, then remove the rosemary and discard the garlic or mash it into the cream for stronger flavor.

4. Mash until smooth:

Drain the potatoes well, return them to the pot, and mash with a potato masher, ricer, or hand mixer until creamy.

5. Season the potatoes:

Gradually mix in the warm cream mixture, then season with kosher salt and black pepper to taste.

6. Serve while hot:

Spoon the mashed potatoes into a serving bowl and garnish with fresh rosemary sprigs and an extra pat of butter, if desired.

Substitutions and Variations

• Dairy-free: Replace the butter with olive oil or plant-based butter and use unsweetened dairy-free cream.
• Lighter texture: Substitute whole milk or half-and-half for some or all of the heavy cream.
• Stronger garlic: Mash the steeped garlic cloves into the potatoes instead of discarding them.
• Herb swap: Use fresh thyme, sage, chives, or parsley for a different aromatic finish.
• Extra richness: Stir in cream cheese, sour cream, or grated Parmesan for a thicker, tangier mash.
• Chunky potatoes: Use a hand masher and stop mixing while small tender pieces remain.
• Loaded variation: Fold in crispy bacon, shredded cheddar, or sliced green onions.
• Rustic potato blend: Mix Yukon gold potatoes with peeled russet potatoes for a lighter, fluffier texture.

Serving Suggestions

Side dishes:

Serve these potatoes with roasted chicken, glazed ham, seared steak, braised beef, or roasted vegetables.

Toppings:

Finish with melted butter, chopped chives, crispy bacon, grated Parmesan, or a few fresh rosemary leaves.

Drinks:

Pair them with sparkling apple cider, a crisp white wine, or a refreshing herb lemonade.

How to Store

Store

Refrigerate leftovers in an airtight container for up to 3 days, adding a splash of cream before reheating.

Freeze

Freeze cooled mashed potatoes for up to 2 months in airtight containers, leaving a little space for expansion.

Prep ahead

Make the potatoes up to 24 hours ahead and refrigerate them; let them sit briefly at room temperature before reheating.

Reheat

Warm gently in a saucepan over low heat or in the microwave, stirring in cream or butter until smooth and hot.

Top Tips

• Start with cold water: Cover the potatoes with cold, salted water so they cook evenly from the center outward.
• Keep the cream warm: Warm dairy blends into the potatoes smoothly and prevents the mash from becoming gluey.
• Avoid overmixing: Mash only until creamy, since excessive beating can make potatoes sticky and dense.
