Ingredients You’ll Need
A great casserole begins with fresh ingredients. Here’s what you’ll need for a classic gluten-free breakfast casserole:
Base Ingredients
- Gluten-Free Bread or Hash Browns (2 cups): Acts as a flavorful base. Brands like Udi’s or Ore-Ida are reliable.
- Eggs (8-10 large): The binding agent and protein powerhouse for your dish.
- Cheese (1 ½ cups): Cheddar, mozzarella, or a mix of both. Feel free to opt for dairy-free if needed.
Flavor Boosters
- Milk or Dairy-Free Milk (1 cup): Adds creaminess. Almond, coconut, or oat milk work beautifully in a gluten-free casserole.
- Protein (1 lb): Sausage, bacon, ham, or even plant-based alternatives—choose your favorite!
- Vegetables (1–2 cups): Options like bell peppers, onions, spinach, and mushrooms add flavor and nutrients.
Seasonings
- Salt (1 tsp) and pepper (½ tsp)
- Garlic powder (½ tsp)
- Smoked paprika (½ tsp)
Ingredient Substitutions
Making adjustments to suit your dietary preferences or what’s available in your kitchen is simple and fun! For creamy consistency, swap out milk with cashew cream or even silken tofu blended with water for a dairy-free and protein-packed alternative. No protein on hand? Chickpeas or black beans are perfect for a plant-based twist. If you’re looking to change up the vegetables, zucchini, broccoli, or even shredded carrots can be used for a vibrant and nutritious substitute. Want bolder flavors? Try swapping smoked paprika with chipotle powder or add a pinch of cayenne for a spicier casserole. Customizing your casserole has never been easier!
Instructions for the Perfect Casserole
Step 1: Preheat Your Oven and Grease a Baking Dish
Preheat your oven to 375°F (190°C) and grease an 8×8 inch (20×20 cm) baking dish with cooking spray or butter. Set aside.
Step 2: Cook Protein and Vegetables
In a skillet, cook your choice of protein until browned. Remove from heat and set aside. In the same skillet, sauté vegetables until slightly softened. You can also use pre-cooked or leftover veggies for convenience!
Step 3: Cut Bread into Cubes or Shred Hash Browns
For the bread base, slice gluten-free bread into cubes. For hash browns, shred using a cheese grater or use pre-shredded options from the store. If you prefer a crispier texture, cook hash browns in a pan with some oil until golden brown before adding to the casserole.
Step 4: Layer Ingredients in Baking Dish
Evenly spread half of your bread or hash browns on the bottom of your greased baking dish. Add half of your cooked protein and vegetables on top. Repeat layering with remaining ingredients.
Step 5: Whisk Eggs and Milk with Seasonings
In a separate bowl, whisk together eggs, milk, and seasonings until well combined. Pour the mixture over the layered ingredients in the baking dish.
Step 6: Add Cheese and Bake
Sprinkle shredded cheese on top of the egg mixture, covering all areas evenly. Bake for 35-40 minutes or until a toothpick inserted in the center comes out clean and cheese is golden brown. Allow to cool for a few minutes before serving.
Variations and Make-Ahead Options
The beauty of a breakfast casserole is that you can make it your own by experimenting with different ingredients! Here are some ideas to get you started:
- Italian Breakfast Casserole: Swap regular bread or hash browns with gluten-free Italian breadcrumbs and add cooked Italian sausage, sautéed bell peppers, onions, and mushrooms. Top with mozzarella cheese and sprinkle some Italian seasoning for a flavorful twist.
- Tex-Mex Breakfast Casserole: Use corn tortillas instead of bread or hash browns and layer with black beans, salsa, jalapeños, and cheddar cheese. Serve with avocado slices and a dollop of sour cream for a delicious Tex-Mex breakfast treat.
- Vegetarian Breakfast Casserole: Omit the meat and add extra veggies like spinach, broccoli, zucchini, cherry tomatoes, or even sweet potatoes for a hearty vegetarian
Step 4: Combine Ingredients
In a large mixing bowl, combine the cooked protein, sautéed vegetables, and bread cubes or shreds. Add in shredded cheese, herbs, or spices of your choice for added flavor. Gently toss everything together until evenly mixed.
Step 5: Prepare the Egg Mixture
In a separate bowl, whisk together eggs, milk, salt, and pepper until well combined. For a creamier texture, you can substitute part of the milk with heavy cream.
Step 6: Assemble the Casserole
Pour the egg mixture over the ingredients in the bowl, ensuring everything is coated. Transfer the mixture into the greased baking dish, spreading it out evenly. Press down lightly to compact the casserole.
Step 7: Top It Off
Sprinkle the top with extra shredded cheese or breadcrumbs for a golden, crispy finish. You can also add a drizzle of olive oil or pats of butter for extra richness.
Step 8: Bake to Perfection
Place the casserole in the preheated oven and bake for 30-40 minutes, or until the top is golden brown and the center is set. To check if it’s done, insert a knife into the center—it should come out clean.
Step 9: Cool and Serve
Remove the casserole from the oven and allow it to cool for about 5-10 minutes. This brief resting time helps the casserole set, making it easier to slice. Serve warm and enjoy!
