Pro Tips Before You Start
Cut evenly – Quarter potatoes to ensure even cooking.
Use warm milk and melted butter – This keeps the potatoes hot and creamy.
Don’t overmix – Especially if using an electric mixer, to avoid gummy texture.
No trivet? – You can cook directly in the insert, but large chunks help prevent sticking.
How to Make Instant Pot Mashed Potatoes (Step-by-Step)
Prepare the Instant Pot
Insert the metal trivet into the pot.
Add 1 cup water or low-sodium chicken broth. Sprinkle in 1 teaspoon of salt.
Prep the Potatoes
Peel and quarter the potatoes into large chunks (about 1 inch thick).
Place them on top of the trivet, starting with the largest pieces so they don’t fall through.
Pressure Cook
Seal the lid and set the valve to “Sealing.” Select manual high pressure and cook for 10 minutes.
When done, carefully quick release the pressure and open the lid.
Mash the Potatoes
Remove the trivet with tongs or an oven mitt, leaving the cooking liquid behind.
Mash the potatoes directly in the pot using a potato masher.
Add Milk & Butter
Pour in warm milk gradually until you reach your desired consistency.
Add softened or melted butter and mix just until combined.
Adjust & Garnish
Taste and adjust seasoning if needed.
For ultra-smooth mashed potatoes, blend with a hand mixer.
Garnish with chopped parsley or chives if using.
What to Serve It With
Thanksgiving turkey or holiday ham
Pot roast or beef stew
Grilled chicken or pork chops
Meatloaf with gravy
Vegetarian mushroom gravy or sautéed green
Variations / Substitutions
Swap milk for sour cream – Adds tangy richness.
Use Yukon Golds – For a naturally buttery flavor.
Add garlic – Cook 2–3 cloves with the potatoes for garlicky goodness.
Dairy-free version – Use olive oil and unsweetened almond milk.
Storage & Leftovers
Fridge – Store in an airtight container for up to 4 days.
Reheat – Warm in a saucepan with a splash of milk or butter until creamy.
Freezer – Freeze in portions; thaw in the fridge and reheat slowly.
FAQs
Do I need to peel the potatoes?
No, but peeling gives you a smoother mash. Skins add texture and nutrients if left on.
Can I double this recipe?
Yes! Just don’t exceed the max fill line.
Cooking time stays the same.
Can I make them ahead of time?
Absolutely! They reheat well and can be kept warm in the Instant Pot using the “Keep Warm” setting.
Can I use an immersion blender?
Yes, but only briefly. Overmixing can lead to a gummy texture.
Is chicken broth better than water?
It adds more flavor but either option works beautifully.
How do I keep them hot for a party?
Use the Instant Pot’s “Keep Warm” feature and stir occasionally.
Can I use red or gold potatoes?
Yes! Just expect a creamier, less fluffy texture than with russets.
