Ingredients
Scale
Potatoes and Liquid
- 3 lbs. russet potatoes (rinsed and scrubbed)
- 5 cups water
Garlic Herb Butter
- 4 Tbsp. butter (salted)
- 4 cloves garlic (finely minced)
- ½ tsp. fresh thyme (finely chopped)
- ½ tsp. fresh rosemary (finely chopped)
Mashed Potato Mix-ins
- â…“ cup sour cream (or a dairy-free alternative)
- â…“ cup milk (or a full-fat plant-based alternative)
- 2 tsp. salt (divided)
- ¼ tsp. black pepper (to taste)
Instructions
- Prepare the Potatoes: After thoroughly rinsing and drying the potatoes, peel them using a vegetable peeler and cut into 1-inch chunks. This ensures even cooking in the Instant Pot.
- Pressure Cook the Potatoes: Add the cubed potatoes to a 6-quart Instant Pot along with 5 cups of water and 1 teaspoon of salt. Seal the lid and set the pressure cooker to high pressure for 8 minutes. Once cooking is complete, perform a quick release to release the pressure safely.
- Make Garlic Herb Butter: While the potatoes cook, melt 4 tablespoons of butter in a small skillet or saucepan over medium-low heat. Add the finely minced garlic and chopped fresh thyme and rosemary. Sauté gently for about 5 minutes, stirring occasionally until fragrant but not browned.
- Drain and Mix the Potatoes: Drain the cooked potatoes in a colander, then return them to the Instant Pot or a large mixing bowl. Add the garlic herb butter, ⅓ cup sour cream, ⅓ cup milk, the remaining 1 to 1 ¼ teaspoons of salt, and black pepper to taste.
- Mash the Potatoes: Using a potato masher, mash the potatoes until you achieve the desired creamy consistency. Adjust seasoning if necessary.
- Serve: Serve the mashed potatoes warm with an optional pat of butter and extra fresh herbs for garnish and added flavor. Enjoy your rich and garlicky side dish!
Notes
- For dairy-free options, substitute butter with a plant-based alternative, sour cream with coconut or cashew-based sour cream, and milk with almond or oat milk.
- Do not overcook potatoes in the Instant Pot, as they can become watery. Use quick release to stop cooking immediately.
- Feel free to add more garlic or herbs if you prefer a stronger flavor.
- If you want extra fluffy potatoes, use a ricer instead of a masher.
- These mashed potatoes pair wonderfully with roasted meat, poultry, or vegetarian main dishes.
