Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Potatoes
The foundation of this recipe, potatoes provide the creamy base. Yukon Golds or Russets work best because they yield a naturally fluffy and buttery consistency, ideal for mashing.

Butter
Butter adds richness and depth, giving the mashed potatoes their luxurious, velvety finish. It enhances the overall flavor, making every bite indulgent and satisfying.

Garlic
Fresh garlic cloves infuse the potatoes with a subtle, aromatic flavor. As they cook with the potatoes, the garlic mellows, creating a perfectly balanced undertone that complements the creaminess.

Heavy Cream
Heavy cream makes the mashed potatoes ultra-smooth and decadent. It enriches the texture, ensuring that the final dish is silky rather than dry or crumbly.

Salt
Salt is essential to enhance all the flavors. When added at the right time, it ensures that the potatoes absorb the seasoning fully, preventing a bland outcome.

Black Pepper
A touch of black pepper provides gentle heat and balance. It cuts through the richness of the butter and cream while adding depth to the dish.

Directions

Begin by peeling and cutting the potatoes into uniform chunks to ensure even cooking. Place the potatoes and garlic cloves into the Instant Pot with water and a pinch of salt. Secure the lid and cook on high pressure for about 10 minutes, followed by a quick release. Once cooked, drain the potatoes well to avoid excess water, which can lead to runny mash.

Return the drained potatoes and garlic to the pot, then add butter. Mash the mixture until smooth, incorporating the butter fully. Gradually pour in the heavy cream while continuing to mash, adjusting the consistency to your preference. Season with additional salt and black pepper to taste. For extra creaminess, a handheld mixer can be used to whip the potatoes to a fluffier texture.

Finally, transfer the mashed potatoes to a serving bowl and garnish with an extra pat of butter or freshly chopped herbs if desired. Serve warm alongside your favorite mains.

Servings and timing

This recipe makes approximately 6 servings, making it perfect for family dinners or small gatherings. The total preparation and cooking time is about 25 minutes, with 10 minutes of pressure cooking and the remaining time dedicated to preparation and mashing.

Storage/reheating

Leftover mashed potatoes should be stored in an airtight container in the refrigerator for up to 3 days. For longer storage, freeze in portions for up to 1 month. To reheat, warm them gently on the stovetop or in the microwave, adding a splash of cream or milk to restore their creamy texture. Stir occasionally to prevent sticking and ensure even reheating.

Variations and Customizations

Mashed potatoes offer endless opportunities for customization. For a more indulgent version, consider adding cream cheese or sour cream for extra tang and creaminess. Parmesan or cheddar cheese can also be incorporated for a cheesy twist that pairs beautifully with roasted meats.

If you prefer lighter mashed potatoes, substitute half-and-half or whole milk in place of heavy cream. Olive oil is another great alternative to butter, giving the dish a lighter Mediterranean flair while still providing richness.

For added texture, fold in crispy bacon crumbles or sautéed onions. Fresh herbs such as chives, parsley, or rosemary can bring a refreshing contrast to the buttery base. If you enjoy a hint of spice, a pinch of paprika or cayenne pepper will add subtle heat.

To make this recipe vegan-friendly, replace butter with vegan margarine and use plant-based milk or cream alternatives such as oat or almond milk. Regardless of the variations you choose, the Instant Pot ensures consistently smooth, flavorful mashed potatoes every time.
