Recipe Overview
- Prep Time: 10 minutes
- Cook Time: 15 minutes
- Broil Time: 5 minutes
- Total Time: 30 minutes
- Servings: 4
- Dietary Type: Vegetarian
Ingredients
- 1 large egg
- 2 cups cauliflower florets, roughly chopped
- 1 cup shredded frozen hash brown potatoes
- 1 teaspoon kosher salt
- ½ teaspoon fresh ground black pepper
- ¼ cup panko breadcrumbs
- ¼ cup grated Parmesan cheese
- 2 teaspoons everything bagel seasoning
Equipment Needed
- 32-ounce (6-inch) soufflé dish
- Instant Pot
- Metal trivet
- Oven
Instructions
-
Begin by preparing your soufflé dish. Lightly spray a 32-ounce (6-inch) soufflé dish with nonstick cooking spray and set it aside. This will ensure your casserole releases easily after cooking.
-
In a medium bowl, beat the egg until light and frothy. This will help bind the other ingredients together.
-
Add the cauliflower florets, shredded frozen hash brown potatoes, kosher salt, fresh ground black pepper, panko breadcrumbs, and grated Parmesan cheese to the bowl with the egg.
-
Mix all the ingredients thoroughly until well combined, ensuring the egg coats all the vegetables and breadcrumbs. The mixture should be slightly sticky but not overly wet.
-
Pour the prepared mixture into the sprayed soufflé dish, spreading it evenly.
-
Place the metal trivet in the bottom of the Instant Pot’s inner pot. Pour in 1 cup of water. The water is essential for creating steam, which cooks the casserole evenly.
-
Carefully lower the soufflé dish onto the trivet inside the Instant Pot. Make sure the dish is stable and not touching the sides of the pot.
-
Cover and lock the Instant Pot lid in place. Ensure the vent is set to the sealing position.
-
Set the Instant Pot to manual on high pressure for 10 minutes. Once programmed, let the Instant Pot work its magic.
-
When the cook time is complete, perform a quick pressure release. Be cautious when releasing the pressure, as steam will escape rapidly. Use a towel or oven mitt to protect your hand.
-
Once all the pressure is released and the pin drops, carefully remove the lid.
-
Gently remove the soufflé dish from the Instant Pot. Be careful, as the dish will be hot.
-
Transfer the dish to the oven and broil for 5 minutes, or until the top is golden brown and bubbly. Keep a close eye on it, as broiling can quickly burn the surface.
-
Remove the casserole from the oven and sprinkle with everything bagel seasoning.
-
Let it cool slightly before serving.
Expert Tips & Tricks
- Cauliflower Prep: Ensure your cauliflower florets are roughly the same size for even cooking. If you have a food processor, you can pulse the cauliflower to achieve a rice-like consistency, but don’t over-process it into a puree.
- Hash Brown Thawing: While you can use frozen hash browns directly, letting them thaw slightly beforehand can help them incorporate more easily into the mixture. Don’t let them get too mushy, though.
- Cheese Variation: Experiment with different cheeses! A sharp cheddar or Gruyere would add a bolder flavor. For a creamier texture, try adding a tablespoon or two of cream cheese to the mixture.
- Breadcrumb Boost: Toast the panko breadcrumbs in a dry skillet for a few minutes before adding them to the mixture. This will enhance their flavor and add a pleasant crunch.
- Preventing a Soggy Casserole: Be sure to drain any excess moisture from the cauliflower and hash browns before combining them. You can gently press them with paper towels to remove excess water.
- Instant Pot Placement: Always use a trivet in your Instant Pot when cooking casseroles to prevent burning on the bottom.
Serving & Storage Suggestions
This Instant Pot Cauliflower Hash Brown Casserole is best served warm. It makes a wonderful side dish for breakfast, brunch, lunch, or dinner. Garnish with a sprinkle of fresh herbs like parsley or chives for an extra touch of freshness.
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, bake in a preheated oven at 350°F (175°C) until heated through, or microwave in short intervals until warm. The casserole may lose some of its crispness upon reheating, but it will still be delicious.
Freezing is not recommended as the texture of the cauliflower and potatoes may change significantly.
