Instant Pot Scalloped Potatoes Recipe for Easy Comfort Food

Scalloped potatoes are a classic comfort food, known for their creamy, cheesy layers of tender potatoes baked to perfection. Using an Instant Pot makes this dish quick and fuss-free, delivering the same rich flavors without the long oven wait. Perfect for busy weeknights or when you crave hearty, cheesy potatoes in a fraction of the time.

Ingredients

• 3 pounds russet potatoes, peeled and thinly sliced
• 1 medium onion, finely chopped
• 3 cloves garlic, minced
• 2 cups shredded cheddar cheese
• 1 cup whole milk or heavy cream
• 1/2 cup unsalted butter, melted
• 2 tablespoons all-purpose flour
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1/2 teaspoon paprika (optional, for flavor)
• 1 teaspoon dried thyme or rosemary (optional)

Instructions

1. Prepare the Potatoes: Peel the potatoes and slice them evenly about 1/8-inch thick. To prevent browning, place sliced potatoes in a bowl of cold water until ready to use, then drain thoroughly.
2. Sauté Aromatics: Turn the Instant Pot to the sauté setting. Add a teaspoon of butter or oil, then cook the chopped onion and minced garlic until translucent and fragrant, about 3-4 minutes. Remove and set aside.
3. Make the Cheese Sauce: In a small bowl, whisk together milk or cream with flour, salt, pepper, and paprika if using. This mixture helps thicken the sauce and prevent curdling. Set aside.
4. Layer Potatoes and Cheese: Lightly grease the inner pot with butter or non-stick spray. Spread a thin layer of sliced potatoes on the bottom, sprinkle with a portion of sautéed onions, and a handful of shredded cheddar. Repeat layers until all ingredients are used, ending with cheese on top.
5. Pour Sauce and Seal: Carefully pour the prepared milk mixture over the layered potatoes. Spread melted butter evenly over the top layer of cheese. Close the lid of the Instant Pot and set the valve to sealing.
6. Pressure Cook: Select high pressure and cook for 10 minutes. Once the cooking time is complete, allow a natural pressure release for 10 minutes, then carefully perform a quick release to release any remaining pressure.
7. Finish and Serve: Open the lid, check the potatoes for doneness (they should be tender), and stir gently if needed. If you want a browned, bubbly top, transfer the dish to a broiler-safe dish and broil for 2-3 minutes until golden. Serve hot, garnished with extra cheese or herbs if desired.

Tips

• Substitutions: Use sweet potatoes for a different flavor or lactose-free milk and cheese for dairy-free versions. You can also add cooked bacon or ham for extra protein.
• Preventing uneven layers: Use a mandoline slicer for uniformly thin potatoes, ensuring even cooking and a smooth texture.
• Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven, adding a splash of milk to keep it creamy.
• Common mistake: Overfilling the Instant Pot can cause uneven cooking or sealing issues. Stick to the maximum fill line and avoid over-layering.

Serving Suggestions

Serve these creamy scalloped potatoes as a hearty side dish alongside roasted chicken, grilled steak, or sautéed vegetables. They also pair beautifully with a simple green salad or steamed broccoli for a balanced meal.

Variations

• Cheese choices: Swap cheddar for Gruyère, Monterey Jack, or Parmesan for different flavor profiles.
• Herb additions: Incorporate fresh herbs like parsley, chives, or thyme into the layers or garnish for added freshness.
• Spicy kick: Add a pinch of cayenne pepper or hot sauce to the sauce mixture for a spicy version.
• Vegan version: Use plant-based cheese, almond milk, and vegan butter to make this dish dairy-free and suitable for vegans.

Storage and Reheating

Leftover scalloped potatoes can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, transfer to an oven-safe dish, cover with foil, and bake at 350°F (175°C) for about 20-25 minutes until heated through. Alternatively, reheat in the microwave in 1-2 minute intervals, stirring halfway through, until hot. For best results, avoid freezing as the texture may become grainy after thawing.

Frequently Asked Questions

Can I make this recipe ahead of time?

Yes, you can assemble the dish and refrigerate it for up to 24 hours before cooking. Just cover tightly and proceed with pressure cooking when ready. This makes it a convenient option for preparing meals in advance.

How do I prevent the potatoes from turning brown?

Immediately after slicing, place the potatoes in a bowl of cold water to prevent oxidation and browning. Drain thoroughly before layering in the Instant Pot to ensure even cooking and prevent excess moisture.

Is it necessary to use a natural release?

Yes, allowing a natural pressure release for 10 minutes helps the dish finish cooking evenly and prevents the cheese sauce from separating. After that, perform a quick release to release any remaining pressure safely.

Can I use frozen potatoes?

It’s best to use fresh or thawed potatoes for even cooking. Frozen potatoes may release excess moisture and lead to a watery dish. If you must use frozen, drain any excess liquid before layering and consider increasing cooking time slightly.

How can I get a crispy top?

After pressure cooking, transfer the scalloped potatoes to a broiler-safe dish, sprinkle with additional cheese or breadcrumbs if desired, and broil for 2-3 minutes until bubbly and golden brown. Keep a close eye to prevent burning.

Can I make this in a larger or smaller Instant Pot?

Adjust the quantities proportionally for different sizes, but stick to the same cooking time for 6-quart or 8-quart models. Ensure not to overfill beyond the maximum line to allow proper sealing and cooking.
