Ingredients You'll Need

The beauty of a Hashbrown Breakfast Casserole is its simplicity! Most ingredients can already be found in your kitchen. Here's what you'll need to get started.

Core Ingredients:

• Frozen Hashbrowns (500g): Ensure they are thawed for even baking.
• Eggs (12 large): The base for that creamy, custard-like texture.
• Cheddar Cheese (2 cups, shredded): Adds that ooey-gooey richness.
• Breakfast Sausage (1 lb) or Bacon (8 slices) (optional): Cooked and crumbled for extra flavor.
• Milk (1 ½ cups): Helps create a fluffy texture.
• Salt and Pepper (to taste): Essential for seasoning.

Optional Add-Ins:

• Onions and Bell Peppers (1 cup each, diced) for added crunch and flavor.
• Spinach or Kale (1 handful, chopped) for a veggie-packed version.
• Hot Sauce (a few dashes) to add a kick.

Step-by-Step Instructions for the Perfect Hashbrown Casserole

Step 1. Prepare Your Ingredients

Preheat your oven to 375°F (190°C). Spray a 9x13-inch baking dish lightly with non-stick cooking spray. If you're including sausage or bacon, cook your meat until crispy, then crumble or chop it into small pieces.

Thaw the frozen hashbrowns and pat them dry to remove any excess moisture. This step ensures your casserole is crispy and not soggy.

Step 2. Assemble Your Egg Mixture

Whisk together the eggs, milk, salt, pepper, and any seasonings you desire. This mixture will bind your casserole together. For an extra creamy result, add a splash of heavy cream or substitute some of the milk with full-fat Greek yogurt.

Step 3. Layer Your Ingredients

• Spread the hashbrowns evenly onto the base of your prepared baking dish.
• Layer in the cooked sausage (or bacon) and any vegetables you’re using.
• Sprinkle shredded cheese generously over the top.

Step 4. Add the Egg Mixture

Slowly pour the whisked egg mixture over the layers, making sure it distributes evenly throughout the dish. Use the back of a spoon to gently press everything down, ensuring the egg mixture soaks into the ingredients.

Step 5. Bake to Perfection

Bake uncovered at 375°F for 40–45 minutes, or until the top is golden brown and the casserole is set in the center. You can check doneness by inserting a knife or toothpick—it should come out clean.

Step 6. Rest and Serve

Allow the casserole to rest for 5–10 minutes before slicing. This step makes it easier to cut clean portions and lets the flavors meld together. Serve warm, and enjoy!

Tips for Customizing Your Hashbrown Breakfast Casserole

• Make it Meat-Free: Swap the sausage or bacon for diced mushrooms, zucchini, or veggie sausage.
• Cheese It Up: Try mixing cheeses. Pepper Jack for a spicy kick or Gruyère for a nutty, creamy profile.
• Spice Lovers: Add jalapeños, cayenne pepper, or a drizzle of sriracha for extra heat.
• Meal Prep Approved: Store leftovers in an airtight container in the fridge for up to four days, or freeze them in individual portions for up to three months.
