Ingredient Breakdown

Potatoes: Yukon Golds or Russets are best for fluffy, creamy texture. Yukon Golds add a naturally buttery flavor, while Russets yield a lighter mash.
Garlic: Roasted garlic brings a subtle sweetness and mellow flavor that blends perfectly into the potatoes.
Butter: The backbone of creamy mashed potatoes – adds richness and smoothness.
Heavy Cream or Half-and-Half: Provides a luscious, velvety consistency. Milk can be used for a lighter version.
Fresh Rosemary: Fragrant and earthy, it infuses the potatoes with warmth.
Salt and Pepper: Essential for balance and to enhance flavor.
Olive Oil (Optional): A drizzle adds an elegant finish and a hint of sophistication.

Step-by-Step Instructions

1. Prep and Boil the Potatoes:
   Peel and cube the potatoes into even-sized pieces. Place them in a large pot of salted water and bring to a boil. Cook for 15–20 minutes until tender and easily pierced with a fork.
2. Roast the Garlic:
   While the potatoes cook, slice the top off a garlic bulb, drizzle with olive oil, wrap in foil, and roast at 400°F for about 30 minutes until soft and golden. Squeeze the roasted cloves from their skins once cooled.
3. Mash the Potatoes:
   Drain the cooked potatoes well. Return them to the pot and let steam escape for a minute. Mash with a potato masher or use a ricer for extra smooth results.
4. Add Creamy Goodness:
   Warm the butter, cream, and roasted garlic together in a small saucepan until melted and aromatic. Pour the mixture into the potatoes and stir gently to combine.
5. Season and Finish:
   Add chopped rosemary, salt, and pepper. Adjust seasoning to taste. Transfer to a serving bowl and drizzle with olive oil or melted butter before serving.

Notes and Top Tips

• Use Warm Cream: Adding cold liquid can make potatoes gluey. Always warm cream and butter before mixing.
• Don’t Overmix: Mash just until smooth; overmixing can make potatoes sticky.
• Make Ahead: Prepare up to two days ahead. Reheat gently in the oven or on the stove with a splash of cream.
• Roast Extra Garlic: It keeps well in the fridge and adds incredible flavor to other dishes.
• For a Healthier Option: Swap half of the potatoes for cauliflower for a lighter, lower-carb version.

Serving Suggestions and Variations

• Perfect With: Roast turkey, baked chicken, beef tenderloin, or gravy.
• Variations:
  • Add Parmesan or cream cheese for extra richness.
  • Mix in roasted shallots or caramelized onions for added sweetness.
  • Use thyme instead of rosemary for a slightly different aromatic touch.
  • Try a half-and-half blend of mashed potatoes and cauliflower for a lighter version.

Storage and Reheating Tips

• Refrigerate: Store in an airtight container for up to 4 days.
• Freeze: Cool completely and store in a freezer-safe bag for up to 2 months. Thaw overnight in the fridge.
• Reheat: Warm on the stovetop or in the oven at 350°F with a splash of cream or butter stirred in to restore creaminess.
