  • Optional Add-Ins: Diced ham, crispy bacon, or sautéed veggies like onions and bell peppers

How to Make the Recipe (Step-by-Step)

  • Bake: Slide the dish into the oven and bake for 40-45 minutes, or until the center is set and the edges are golden brown.
  • Cool and serve: Let it cool slightly before slicing to make serving easier and enjoy your homemade breakfast casserole!

Expert Tips for Success

Thaw your hash browns
Don’t over-bake
Use fresh eggs
Customize it
Pre-mix the cheese for even flavor
Let it rest before serving
Double the batch for leftovers

Variations and Customizations

You can easily swap ingredients to suit different diets and tastes. For a vegetarian option, skip the meat and add extra vegetables—think mushrooms, spinach, or zucchini. Love spice? Add some chopped jalapeños or a sprinkle of red chili flakes. For low-carb, ditch the hash browns and use cauliflower rice instead—it’s surprisingly tasty and light. Gluten-free? No problem. Most of the basic ingredients are already gluten-free, but double-check any seasoning packets or pre-shredded cheese to make sure they’re safe.

Nutritional Information

One serving comes in around 280 calories, thanks to the hearty mix of protein and fats from the eggs and cheese. There’s about 12g of protein, making it great for keeping you full. If you use turkey bacon or skip the cheese, you can cut down on fat too. For anyone tracking carbs, the hash browns bring about 15-20g per serving, but cauliflower rice can slash that in half.

Storage and Reheating Instructions

Got leftovers? Pop them into an airtight container, and they’ll stay good in the fridge for up to 4 days. If you’re making it ahead, it’s freezer-friendly too—just wrap individual servings tightly so they don’t dry out, and freeze for up to 2 months. For reheating, warm slices in the oven at 350°F for about 10-15 minutes, or use the microwave for 1-2 minutes (though the oven keeps that crispy texture).
