Scalloped potatoes cooked in the Instant Pot are a quick and effortless way to enjoy this classic side dish with a rich, creamy texture. Using the pressure cooker cuts down cooking time significantly while still delivering tender potatoes layered in a flavorful sauce, making it perfect for busy weeknights or when entertaining guests.
Ingredients
- 3 pounds russet potatoes, peeled and thinly sliced
- 1 medium onion, finely chopped
- 3 cloves garlic, minced
- 2 cups shredded sharp cheddar cheese
- 1 cup whole milk
- 1 cup heavy cream
- 4 tablespoons unsalted butter, divided
- 2 tablespoons all-purpose flour
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon paprika (optional, for color)
- Fresh thyme or parsley for garnish (optional)
Instructions
- Prepare the potatoes: Peel the russet potatoes and slice them as thinly as possible, about 1/8 inch thick. Uniform slices ensure even cooking and a cohesive dish.
- Sauté aromatics: Turn the Instant Pot to the sauté setting. Melt 2 tablespoons of butter, then add chopped onion and minced garlic. Cook, stirring frequently, until fragrant and translucent, about 3 minutes. Remove from the pot and set aside.
- Make the sauce: In a small bowl, whisk together the milk, heavy cream, flour, salt, pepper, and paprika. This mixture will thicken during cooking, creating a creamy sauce.
- Assemble the dish: Layer half of the sliced potatoes in the bottom of the Instant Pot. Sprinkle with half of the sautéed onions, then pour half of the sauce over the layer. Repeat with remaining potatoes, onions, and sauce.
- Cook under pressure: Close the lid, set the valve to sealing, and cook on high pressure for 8 minutes. Once cooking is complete, allow a natural pressure release for 10 minutes, then carefully release any remaining pressure.
- Finish the dish: Open the lid, sprinkle the shredded cheddar cheese evenly over the potatoes. Cover the Instant Pot with the lid (or a heat-safe cover) and let sit for 5 minutes to melt the cheese.
- Serve: Carefully transfer the scalloped potatoes to a serving dish, garnish with fresh thyme or parsley if desired, and serve hot.
Tips
- Slice uniformly: Use a mandoline if possible for even slices, which ensures consistent cooking and presentation.
- Cheese options: Feel free to substitute or mix cheeses, such as Gruyère or Monterey Jack, for different flavor profiles.
- Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven to prevent drying out.
- Avoid overfilling: Do not fill the Instant Pot beyond the max fill line to prevent spills or safety issues during pressure cooking.
Serving Suggestions
Serve these creamy scalloped potatoes alongside roasted chicken, grilled steak, or a crisp green salad for a well-rounded meal. They also pair beautifully with roasted vegetables or a simple protein like baked fish. For a festive touch, sprinkle additional fresh herbs or a dash of paprika before serving.
Variations
- Cheese alternatives: Use a blend of cheeses such as mozzarella, Parmesan, or pepper Jack for different flavors and textures.
- Vegan version: Substitute plant-based milk and vegan cheese, and skip or replace butter with olive oil or vegan margarine.
- Herb infusion: Add herbs like thyme, rosemary, or chives into the sauce for added aroma and flavor.
- Meat additions: Incorporate cooked bacon bits, ham, or cooked ground beef between layers for a heartier dish.
Storage and Reheating
Allow the scalloped potatoes to cool completely before transferring to an airtight container. Store in the refrigerator for up to 3 days. To reheat, microwave on medium power in 1-minute intervals until heated through, or reheat in a covered oven-safe dish at 350°F (175°C) for about 15-20 minutes. The dish may thicken upon refrigeration; stir in a splash of milk during reheating to restore creaminess.
Frequently Asked Questions
Can I use sweet potatoes instead of russet potatoes?
Yes, sweet potatoes can be used for a slightly sweeter and more nutritious variation. Keep in mind that cooking times may vary slightly, so check for tenderness after the initial cooking cycle.
Is it necessary to peel the potatoes?
Peeling is recommended for a smoother texture, but leaving the skins on can add a rustic look and extra fiber. Just ensure potatoes are thoroughly washed if you choose to keep the skins.
Can I prepare this dish ahead of time?
Yes, you can assemble the layered dish a day in advance, store it in the refrigerator, and cook it in the Instant Pot when ready. Add a few extra minutes to the pressure cooking time if the dish is cold.
How do I prevent the dish from burning or sticking to the bottom?
Ensure you deglaze the pot after sautéing by scraping up any browned bits with a little of the sauce mixture. Also, avoid overfilling and use the trivet if you’re concerned about direct contact with the bottom.
Can I make this dish dairy-free?
Yes, substitute plant-based milk and cheese options, and use vegan butter or olive oil. The texture may differ slightly, but it will still be delicious and creamy.
What if I want a crispy top?
After pressure cooking, sprinkle additional cheese and a little breadcrumbs on top, then use the sauté function or transfer to a broiler for 2-3 minutes until golden and crispy.
With these tips and steps, you’ll be able to make perfect, creamy scalloped potatoes in your Instant Pot every time. This dish combines convenience with comfort, making it a go-to side for any meal.
