What Ingredients are in Creamy No-Drain Instant Pot Mashed Potatoes?
For these deliciously simple Instant Pot mashed potatoes, you’ll only need a handful of basic ingredients that transform into creamy, fluffy goodness with minimal effort.
- 2 lbs russet potatoes, cubed into even pieces
- 1 cup water
- 3 tablespoons butter
- 1/4 cup milk
- Salt and pepper to taste
Feel free to customize these basic ingredients by swapping some of the milk with sour cream or cream cheese for an even creamier texture, or add garlic powder or fresh herbs if you’re feeling fancy.
How to Make these Creamy No-Drain Instant Pot Mashed Potatoes
Step 1: Prepare Your Potatoes
Wash and peel 2 pounds of russet potatoes, then cut them into evenly-sized cubes (about 1-inch pieces) to guarantee they cook uniformly in the Instant Pot.
Step 2: Add Potatoes and Water to Instant Pot
Place your cubed potatoes directly into the Instant Pot insert and pour in 1 cup of water—just enough liquid to create steam without requiring draining later.
Step 3: Seal and Set the Instant Pot
Secure the lid on your Instant Pot, making sure the valve is set to “Sealing” position, then set to Manual/High Pressure for 8 minutes—trust me, the timing is perfect for that ideal fluffy-yet-creamy texture.
Step 4: Quick Release the Pressure
Once the cooking cycle completes, carefully perform a quick pressure release by switching the valve to “Venting” (mind the steam, it’s like a potato-scented sauna for your kitchen cabinets).
Step 5: Add Butter and Milk
With potatoes still hot, add 3 tablespoons of butter and ¼ cup of milk directly to the pot—no draining required, which means all that potato flavor stays right where it belongs.
Step 6: Mash to Desired Consistency
Use a potato masher or hand mixer to mash the potatoes until they reach your preferred level of smoothness—some folks like a few lumps for character, others prefer them silky smooth. For the silkiest, most consistent texture, a premium food processor can make quick work of your mashed potatoes while ensuring no lumps remain.
Step 7: Season to Taste
Add salt and pepper to taste, stirring gently to incorporate all the seasonings evenly throughout your creamy masterpiece.
Step 8: Keep Warm Until Serving
If you’re not serving immediately, set your Instant Pot to “Keep Warm” mode, which maintains the perfect temperature without drying out your mashed potatoes—they’ll stay deliciously creamy until the rest of your meal is ready.
What to Serve with Creamy No-Drain Instant Pot Mashed Potatoes
These velvety mashed potatoes are the perfect dinner sidekick for so many meals.
Pair them with a juicy pot roast or meatloaf, where they’ll soak up all those savory drippings like a dream. For something lighter, serve alongside roasted chicken and steamed green beans with a touch of lemon.
Got some gravy? Pour it right on top and watch these potatoes transform into pure comfort food heaven.
For a complete meal, add a simple side salad with vinaigrette to balance the richness. They’re also wonderful with grilled salmon for a more elegant dinner option.
The beauty of these potatoes is their versatility—they’ll complement practically any protein and make even the simplest weeknight dinner feel special.
