• Milk: Milk helps to create the creamy, rich texture that makes this casserole so comforting and delicious. It also helps to bind all the ingredients together.
• Eggs: The cornerstone of any breakfast dish, eggs provide structure and richness to the casserole. They also add a good dose of protein, making this dish a filling breakfast option.
• Gruyere Cheese: Known for its creamy, nutty flavor, Gruyere cheese melts beautifully, making it a great choice for this casserole. It adds a wonderful creaminess and a sophisticated flavor profile to the dish.
• Ground Mustard: A pinch of ground mustard brings a subtle tanginess to the casserole, balancing out the rich, creamy elements and adding an extra layer of flavor.

How to Make Gluten Free Breakfast Casserole

Preheat Oven and Prepare Bread: Preheat your oven to a temperature of about 350 degrees. While it is heating up, cube your gluten-free bread and distribute it evenly at the bottom of the dish, specifically a greased casserole dish that measures about 13x9 inches.

Step 3.

Bake: Put your casserole in the oven and let it cook for about 25-35 minutes, or until it is cooked all the way through. Enjoy your delicious breakfast casserole!

Variations

• Sausage Swap: If you're not a big fan of bacon or just want to mix it up, try adding sausage instead. You can use Italian sausage, turkey sausage, or even homemade breakfast sausage. Just make sure it is cooked thoroughly before adding it to your casserole.
• Try Different Cheese: If gruyere isn't your cheese of choice, don't worry! You can experiment with different cheeses like sharp cheddar, Monterey Jack, or Swiss cheese. Each cheese will give your gluten-free breakfast casserole a unique flavor profile.
• Lighter Version: If you're watching your calorie intake, you can make a lighter version of this casserole by using half egg yolks and half egg whites. This will reduce the fat content without compromising on the taste or texture.
• Add Veggies: Want to sneak in some extra veggies? Try sautéing some green bell pepper, red bell pepper, or green onions and adding them to your casserole. This will not only add a pop of color but also increase the nutritional value of your breakfast.
• Leftover Ham: Have some leftover ham from your holiday brunch? This is a great option to use it up. Replace the bacon with diced ham for a delicious twist to your breakfast casserole.

Helpful Tips

• Choose Quality Bread: The choice of bread is crucial in this recipe. Udi's® Gluten Free Multigrain Bread is a great option, but feel free to use your favorite gluten-free bread. Make sure that it is cubed properly to soak up the egg mixture effectively.
• Cook the Bacon Crisp: For a flavorful and crispy addition to your casserole, make sure that your bacon is cooked until it is crisp. Once cooked, place it on a paper towel-lined plate to drain excess grease.
• Preheat the Oven: Preheating your oven to the right temperature (350 degrees) is essential for the perfect bake. This guarantees that your casserole cooks evenly and thoroughly.
• Layer Your Ingredients: Start by placing your cubed bread at the bottom of the dish, follow with cheese and bacon crumbles. This layering technique helps guarantee a balanced distribution of ingredients in every bite.
• Soak The Bread: After pouring the egg mixture over the cubed bread, press down so all the bread is under the liquid. This step is crucial as it allows the bread to soak up the egg mixture, resulting in a moist and flavorful casserole.
• Make Ahead: This gluten-free breakfast casserole is a fantastic make-ahead breakfast option. You can prepare it the night before and just pop it in the oven the next morning. This is especially convenient for busy mornings or holiday brunches.
