➡️ Ingredients

⏲ How to make this hash brown breakfast casserole

This is an overview of the recipe’s instructions. The full instructions can be found in the recipe card at the bottom of this post.

• Preheat Oven: Preheat oven to 350 degrees F (176 degrees C). Coat a 9×13-inch baking dish with nonstick cooking spray.
• Cook Bacon: In a large skillet over medium heat, cook chopped bacon until crispy. Use a slotted spoon to scoop the bacon out and transfer it to a paper towel-lined plate.
• Whisk Eggs: To a large mixing bowl, add eggs, salt, and pepper. Whisk together until eggs are beaten.
• Prepare Egg Mixture: Add bacon, frozen hash browns, shredded cheddar, cottage cheese, and any optional ingredients like onions and bell peppers to the bowl of beaten eggs. Stir together until well combined.
• Transfer Egg Mixture To Baking Dish: Pour mixture into the prepared baking dish, spreading it out evenly using a rubber spatula.

• Add Cheese: Optionally, sprinkle a little more shredded cheddar on top.
• Bake: Transfer the baking dish to the oven and bake for 55-60 minutes, or until the casserole is set and the top is lightly golden brown. Optionally, transfer the baking dish to the top rack of the oven under the broiler and broil for about 30-60 seconds, watching carefully to avoid burning.
• Cool Then Serve: Remove the casserole from the oven and allow it to cool for a few minutes before garnishing it with green onions or chives, then serving.

👉 Ingredient substitution suggestions

• Bacon: Substitute with turkey sausage, pork sausage, turkey bacon, or diced ham. For a vegetarian option, use tofu. You can also altogether omit the bacon.
• Shredded Cheddar Cheese: Shredded cheese like mozzarella, Swiss, or pepper jack will all work.
• Cottage Cheese: Use Greek yogurt, sour cream, or ricotta cheese.

✨ Variations

• Include more veggies in the egg mixture like spinach, mushrooms, and/or tomatoes.
• Mix fresh herbs into the egg mixture, like parsley, thyme, or chives, for a fresh flavor.
• Add diced jalapeños or a pinch of red pepper flakes to the egg mixture for added heat.
• Garnish with sour cream, salsa, and/or avocado slices for added flavor and texture.

〰️ How to serve

• Salad — Pair with creamy dill cucumber salad, Caesar salad, or mixed greens with vinaigrette.
