Ingredients
- 15 medium red skinned potatoes, diced
- 3 tablespoons minced garlic
- 1/2 cup parmesan cheese, grated
- 3 tablespoons margarine (or butter)
- 1 cup water
- 1 teaspoon salt
- 1 teaspoon pepper
- Parsley for topping (optional)
Instructions

- Step 2: Secure the Instant Pot lid and set the valve to the sealed position. Press the pressure cook/manual button and set the timer for 5 minutes. It will take about 10 minutes to reach pressure before cooking.

- Step 4: Serve warm, topped with parsley if desired to add a fresh, colorful touch.
Tips & Variations
- Use butter instead of margarine for a richer taste and creamier texture.
- Add a splash of cream or milk after blending for extra smoothness.
- For a stronger garlic flavor, sauté the garlic lightly before adding it to the potatoes.
- Try mixing in some shredded cheddar cheese for a cheesy twist.
Storage
Store leftover mashed potatoes in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or on the stovetop with a splash of milk or water to restore creaminess.

FAQs
Can I use other types of potatoes for this recipe?
Yes, Yukon Gold or Russet potatoes also work well for mashed potatoes in the Instant Pot. Just adjust the cooking time slightly if needed, as they may cook a bit faster or slower.
Do I have to use an Instant Pot to make these mashed potatoes?
No, you can boil the diced potatoes on the stove until tender, then mash and mix with garlic, parmesan, and margarine. However, the Instant Pot speeds up the process and makes it hands-off.
