Cooking Steps

Prepare mise en place by peeling and cutting 3 pounds (about 6-8 medium potatoes) into uniform chunks (approximately 5 cm/2 inches) to guarantee even cooking.
Place the potato chunks into a large pot and fill with cold water until the potatoes are fully submerged. Add 1 teaspoon of salt to the water.
Heat the pot over medium-high heat until the water reaches a rolling boil (around 100 °C/212 °F). Once boiling, reduce heat to medium-low and cover, simmering for 15-20 minutes until the potatoes are fork-tender (easily pierced with a fork).
Drain the cooked potatoes in a colander and allow them to sit for 2-3 minutes to let excess moisture evaporate. This helps prevent watery mashed potatoes.
Return the drained potatoes to the pot over low heat. Add 1/2 cup (1 stick) of unsalted butter, 1 cup of heavy cream, and 1/2 cup of milk to the pot. For added flavor, include 2-3 cloves of minced garlic (optional).
Use a potato masher or a ricer to mash the mixture until smooth and creamy, guaranteeing there are no lumps. Stir until all ingredients are well combined. Adjust seasoning with additional salt and 1/2 teaspoon of black pepper to taste.
For extra creaminess, fold in 4 ounces of softened cream cheese (optional) until incorporated.
Transfer the mashed potatoes to a large, greased oven-safe dish, smoothing the top with a spatula.
If making ahead, cover tightly with plastic wrap and refrigerate for up to 2 days.
To reheat, preheat your oven to 190 °C (375 °F) and position the oven rack in the middle.
Remove plastic wrap from the dish and cover it with aluminum foil.
Bake for 30 minutes, then remove the foil and bake for an additional 10-15 minutes until heated through and the top starts to turn golden brown. The internal temperature should reach at least 74 °C (165 °F).
If desired, garnish with chopped chives or parsley before serving for a pop of color and freshness.
Allow the mashed potatoes to rest for 5 minutes before serving to help set their texture.

Variations

Garlic & Herb Mashed Potatoes: Incorporate 2 tablespoons (30 mL) of freshly chopped rosemary and thyme for an aromatic flavor boost alongside the garlic.

Tips on plating and presentation

After exploring some delicious variations on mashed potatoes, it’s time to focus on how to plate and present them beautifully.

I like to use a shallow bowl for a dramatic effect and create a swirl with the back of a spoon. Topping with herbs or drizzling olive oil adds color.

For extra flair, consider serving alongside roasted garlic or crispy bacon bits.

What other dishes can I pair it with?

When planning a meal, I love thinking about what dishes will complement my make-ahead mashed potatoes.

Roasted turkey is a classic pairing, as its savory flavors blend perfectly with the creamy potatoes. I also enjoy serving maple-glazed Brussels sprouts and cranberry sauce for a touch of sweetness.

Finally, a rich gravy elevates the entire spread, making every bite worthwhile.

What drinks can I pair it with?

Wondering what drinks pair well with my make-ahead mashed potatoes?

I always love serving a crisp white wine, like Sauvignon Blanc, to complement the creamy texture.

For a non-alcoholic option, sparkling apple cider brings a revitalizing contrast.

If I’m feeling cozy, a rich hot chocolate can be delightful as well.

Choose what fits your meal, and enjoy every bite!
