Every brunch menu should include a simple one-dish recipe. This breakfast casserole is made with eggs, chicken sausage, cheese, and fresh tomato to create a hearty, protein-rich, healthy gluten-free breakfast.

Even if you don't follow a strictly gluten-free diet, you can still enjoy this flavorful and hearty breakfast dish. Research shows that eating a bigger breakfast can give you more energy throughout the day and even promote healthy weight management.


  • 5 slices gluten-free bread
  • 5 links breakfast-style chicken sausage
  • 6 large eggs
  • 1/2 cup half and half
  • 1/4 cup fresh basil leaves
  • 3/4 teaspoon kosher salt
  • 1 cup cheddar cheese, shredded
  • 1 large tomato, chopped
  • Freshly ground black pepper to taste


  1. Preheat oven to 350F.

  2. Spray a 9x9 square baking dish with nonstick spray.

  3. Toast slices of bread. Once cool enough to handle dice into large pieces.

  4. If sausage is frozen, thaw in the microwave or skillet according to package directions and then roughly chop.

  5. Evenly distribute bread and sausage in the bottom of the prepared baking dish and set aside.

  6. Combine the eggs, half and half, and basil in blender; season with salt and pepper.

  7. Blend for 30 seconds.

  8. Pour the egg mixture into prepared dish.

  9. Sprinkle with cheese and tomato.

  10. Carefully place in the oven and bake for 20 to 25 minutes or until eggs are set.

  11. Remove from the oven and allow to cool for at least 15 minutes before serving.

Variations and Substitutions

To change up the flavors, try replacing the basil with any fresh green herb such as parsley, chives, or tarragon. Swiss cheese and broccoli are also just as delicious as cheddar and tomato. Do your best to stick to just 1 cup of cheese to keep the fat and calories in check.

Cooking and Serving Tips

  • Assemble the ingredients ahead of time and bake just before your company arrives or the family gets up to start their day.
  • Check if the eggs are cooked by pressing down gently on the top of the casserole and make sure no liquid egg runs out. If the top of the casserole begins to look too brown before the eggs are cooked through, cover loosely with aluminum foil for the remainder of cook time.
  • If you have any leftovers, they are perfect for a brown bag lunch.
