How to Make Gluten-Free Breakfast Casserole

This recipe is surprisingly easy to pull together. Follow these steps, and you’ll have a delicious breakfast ready to impress everyone at the table.

1. Prep Your Ingredients

• Preheat your oven to 375°F (190°C).
• Grease a 9×13-inch baking dish with butter or non-stick spray.

2. Cook the Protein

• If using sausage or bacon, cook it in a skillet until browned and slightly crispy. Drain excess grease and set it aside.

3. Assemble the Casserole

• Spread the thawed hash browns evenly across the bottom of the greased dish.
• Sprinkle the cooked sausage (or other protein) evenly over the hash browns.
• Add a layer of shredded cheese on top, reserving a bit for later.
• Scatter the green onions over the cheese layer.

4. Make the Egg Mixture

• In a large bowl, whisk together the eggs, milk, salt, and pepper. Pour this mixture evenly over the casserole, ensuring it covers all the ingredients.

5. Bake

• Top the casserole with the remaining cheese.
• Cover with foil and bake for 30 minutes.
• Remove the foil and bake for an additional 15 minutes, or until the cheese is melted and the casserole is golden brown.

6. Rest and Serve

• Let the casserole rest for 10 minutes before slicing and serving. This helps it set and makes cutting easier.

Tips for Success

• Make It Ahead: Assemble the casserole the night before, cover it, and refrigerate. In the morning, bake it straight from the fridge. Add 10 extra minutes to the baking time.
• Don’t Skip Draining Hash Browns: Excess moisture from frozen hash browns can make the casserole soggy, so be sure to drain them well.
• Use High-Quality Cheese: Choose a cheese that melts well for the creamiest texture. Cheddar, mozzarella, or a blend works perfectly.

Variations to Try

This recipe is incredibly versatile. Here are some fun ways to customize it:

• Vegetarian Option: Skip the meat and load up on veggies like bell peppers, spinach, and mushrooms.
• Spicy Twist: Add diced jalapeños or a sprinkle of red pepper flakes for some heat.
• Dairy-Free: Use a dairy-free milk like almond or oat and opt for vegan cheese.
• Southwestern Style: Add black beans, salsa, and a dash of cumin for a Tex-Mex flair.
• Low-Carb: Replace the hash browns with shredded zucchini or cauliflower rice.

Why Make It Ahead of Time?

Making this gluten-free breakfast casserole ahead of time is a game-changer. You’ll save precious time in the morning, especially if you’re hosting guests or trying to juggle multiple tasks. The flavors also deepen overnight, making the casserole even more delicious when baked the next day.
