Ingredients
- 32 oz (900 g) frozen hash browns (shredded or cubed)
- 1 cup (240 ml) sour cream
- 1 cup (120 g) shredded cheddar cheese
- 1/2 cup (120 ml) melted butter
- 1 small onion, finely chopped (about 1/2 cup)
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1/2 teaspoon black pepper
- 1/2 teaspoon salt (adjust to taste)
- 1/4 teaspoon paprika (optional, for color)
- 1/2 cup (50 g) shredded mozzarella cheese (optional, for topping)
<2 tablespoons chopped fresh parsley (optional, for garnish)
Instructions
- Prepare the Instant Pot: Place the trivet inside the bottom of your Instant Pot. Add 1 cup of water to the pot, which is necessary for steaming.
- Mix the ingredients: In a large bowl, combine the frozen hash browns, sour cream, shredded cheddar, melted butter, chopped onion, garlic powder, onion powder, black pepper, salt, and paprika. Mix well until all ingredients are evenly incorporated.
- Transfer to a baking dish: Lightly grease a 7-inch (18 cm) springform or oven-safe dish that fits inside your Instant Pot. Pour the hash brown mixture into the dish and spread evenly.
- Cover the dish: Use foil to tightly cover the dish, sealing in moisture and preventing condensation from dripping onto the casserole during cooking.
- Pressure cook: Place the covered dish on the trivet inside the Instant Pot. Close the lid and set the valve to sealing. Cook on high pressure for 20 minutes.
- Natural release: When cooking time is complete, allow a natural pressure release for 10 minutes, then carefully turn the valve to venting to release any remaining pressure.
- Finish with cheese and broil (optional): Remove the dish carefully from the Instant Pot. If desired, sprinkle shredded mozzarella on top. For a crispy, golden topping, transfer the casserole to a preheated broiler for 3-5 minutes, watching carefully to prevent burning.
- Garnish and serve: Sprinkle with chopped parsley if using. Let sit for 5 minutes before serving to allow the casserole to set.
Tips
- Substitutions: You can substitute sour cream with Greek yogurt for a healthier option or use shredded Monterey Jack or Pepper Jack cheese for a different flavor profile.
- Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave or oven until warmed through.
- Prevent overcooking: Be cautious with the broiler step to avoid burning the cheese. Keep a close eye and remove promptly when golden.
- Dish size: Adjust the size of your baking dish accordingly, ensuring it fits comfortably inside your Instant Pot with space for steam circulation.
Serving Suggestions
This hash brown casserole pairs wonderfully with scrambled eggs, crispy bacon, or sausage links for a hearty breakfast. It also makes a great side dish for roasted chicken, beef, or grilled vegetables at dinner. Consider adding a fresh side salad to balance the richness of the casserole.
Variations
For a twist on the classic, try adding cooked bacon bits, chopped green onions, or sautéed bell peppers into the mixture. You can also swap the cheese for a spicy pepper jack or a smoky smoked gouda for different flavor profiles. Vegetarian options include mixing in cooked vegetables like spinach, mushrooms, or zucchini for added nutrition and color.
Storage and Reheating
Leftover hash brown casserole can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, microwave individual servings for 1-2 minutes or until heated through. For larger portions, reheat in a 350°F (175°C) oven for about 15-20 minutes, covered with foil to prevent drying out. If adding cheese, sprinkle some on top before reheating for extra flavor.
Frequently Asked Questions
Can I make this casserole ahead of time?
Yes, you can prepare the mixture a day in advance, store it covered in the refrigerator, and then transfer to the dish and cook as directed. For best results, add the cheese topping just before broiling to keep it fresh and melty.
Is it necessary to use frozen hash browns?
Frozen hash browns are recommended for convenience and consistent results, but you can use fresh shredded potatoes if you grate them yourself. Just be sure to squeeze out excess moisture to prevent sogginess.
Can I use fresh potatoes instead of frozen hash browns?
Yes, but you’ll need to par-cook the fresh potatoes first by boiling or roasting, then shredding or dicing them before mixing. Adjust the cooking time accordingly, as fresh potatoes may require slightly longer pressure cooking.
How do I prevent the casserole from drying out?
Ensure you use enough sour cream and melted butter in the mixture, and keep the dish covered during cooking. Adding a little extra sour cream or cheese on top before broiling can also help maintain moisture.
Can I make this recipe vegan?
Absolutely. Substitute sour cream with plant-based alternatives like coconut or cashew-based sour cream, use vegan cheese, and omit butter or replace it with a vegan butter substitute. Adjust seasonings as needed for flavor.
What if my casserole is not cooked through after 20 minutes?
If the mixture isn’t tender or heated through, simply seal the lid again and cook for an additional 5-10 minutes under high pressure. Always check for doneness before releasing pressure.
