Ingredients for thanksgiving make ahead mashed potatoes crowd recipe
- 5 lb russet potatoes
- 8 tbsp butter
- 1 cup heavy cream
- 1 cup whole milk
- 4 cloves garlic minced
- 2 tsp salt
- 1 tsp black pepper
- 1/2 tsp nutmeg
- 4 tbsp sour cream
- 2 tbsp fresh chives chopped
- 1 tbsp fresh thyme
- 1/4 tsp cayenne pepper
Russet potatoes are essential because their starch content creates the fluffiest texture possible. You can substitute half the heavy cream with additional whole milk if preferred, though the richer version reheats more beautifully without drying out.
Fresh herbs make an enormous difference in this make ahead side dish, but dried thyme works acceptably in a pinch. Roasting your garlic cloves before mincing them adds sweetness and prevents harsh flavors from developing overnight in the refrigerator.
Step-by-step make ahead mashed potatoes instructions
1. Peel and cut your five pounds of potatoes into uniform two-inch cubes. Place them in a large pot covered with cold salted water and bring to a boil over high heat, then reduce to medium and simmer for 12-15 minutes until fork-tender. Drain thoroughly in a colander.
2. While potatoes cook, mince your four garlic cloves finely or roast them for sweeter flavor. Heat the butter gently in a small saucepan with the minced garlic until fragrant but not browned, approximately three minutes.
3. Return drained potatoes to the hot pot and mash until mostly smooth. Add the garlic butter mixture and stir gently until combined throughout the potato base.
4. Pour in the heavy cream and whole milk slowly while stirring constantly. This thanksgiving make ahead mashed potatoes crowd recipe requires gentle folding rather than aggressive mixing to prevent gluey texture from developing.
5. Fold in the sour cream, chopped fresh chives, and fresh thyme until evenly distributed. Season with salt, black pepper, nutmeg, and cayenne pepper, then taste and adjust seasonings to your preference.

7. When ready to serve, preheat your oven to 350°F and cover the dish with foil. Bake for 25 minutes until heated through, then remove foil and bake an additional five to ten minutes until the top is lightly golden.
