Why This Recipe Is a Great Choice

This casserole is a brilliant choice because it’s fast, flexible, and full of color. The mix of diced vegetables gives a fresh, garden-picked look and a flavorful bite in every square. Using gluten-free bread keeps it safe for those avoiding gluten without sacrificing the comforting, bread-forward texture of a traditional strata. It’s also a great way to use up odds and ends from the fridge and makes portioning for a family or for meal prep effortless. If you want a sweeter brunch twist later, pair a slice with something like our Apple Pie French Toast Casserole for a full spread that balances savory and sweet.

Flavor and Texture

Expect a golden top, custardy interior, and bursts of tender vegetables throughout. The eggs and milk create a silky, souffle-like base that binds the cubed bread and veggies into a cohesive slice. If you add shredded cheese, it melts into little pockets of creamy richness and helps the top develop that irresistible light brown finish. The bread soaks up the custard but still keeps enough structure to slice neatly, offering a contrast between soft center and slightly crisp edges. Fresh herbs or a dash of smoked paprika can lift the flavors even more.

Ingredients

• 6 large eggs
• 2 cups diced vegetables (bell peppers, onions, spinach, etc.)
• 1 cup gluten-free bread, cubed
• 1 cup milk (dairy or non-dairy)
• 1 cup shredded cheese (optional)
• Salt and pepper to taste
• Olive oil or butter for greasing

Step by Step Instructions

1. Preheat the oven to 375°F (190°C). Grease a 9×13 inch baking dish with olive oil or butter.
2. In a large mixing bowl, whisk together the eggs and milk. Season with salt and pepper.
3. Add the diced vegetables and cubed gluten-free bread to the egg mixture and stir to combine.
4. Pour the mixture into the greased baking dish. If using, sprinkle the top with shredded cheese.
5. Bake in the preheated oven for 30-35 minutes or until the casserole is set and lightly golden on top.
6. Let it cool for a few minutes before cutting into squares and serving.

Tips for Best Results

Use day-old gluten-free bread if possible so the cubes absorb custard without becoming too soggy. Chop vegetables into similar-size pieces so every bite is balanced; quick-sauté of onions and peppers softens them and concentrates sweetness. When using non-dairy milk, choose a neutral, unsweetened variety to keep savory notes bright. If you like a fluffier texture, whisk the eggs a bit longer to incorporate air before mixing. Finish with chopped parsley or chives for a fresh visual pop and subtle herbiness.

Storage and Make Ahead

This casserole stores well in an airtight container in the refrigerator for up to three days and can be reheated in the oven or microwave for quick breakfasts. For easy meal prep, assemble the casserole in the dish the night before and refrigerate uncovered to let the bread soak slightly; bake the next morning from chilled, adding a few extra minutes to the baking time. You can also freeze individual portions wrapped tightly, then thaw overnight in the fridge before reheating.
