In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add 1/2 cup of diced red onion and 1 cup of diced bell peppers. Sauté these veggies until they soften, which takes about 5 minutes. 3. Next, stir in 1 cup of chopped spinach and cook for about 2 minutes. This helps wilt the spinach and blend the flavors. 4. In a large mixing bowl, whisk together 6 large eggs, 1 cup of milk, 1 teaspoon of garlic powder, 1 teaspoon of onion powder, and salt and pepper to taste. Mix until smooth. 5. Add the sautéed veggies to the egg mixture. Then, fold in 2 cups of diced bread and half of the 1 cup of shredded cheese. Gently mix until the bread is coated well. 1. Grease a 9x13 inch baking dish and pour the mixture into it. Spread the mixture evenly across the dish. 2. Top with the remaining cheese. This creates a nice, cheesy crust on top. 3. Bake in the preheated oven for 35-40 minutes. Check for doneness by inserting a toothpick in the center. It should come out clean when ready. 1. Once baked, let the casserole cool for a few minutes before slicing. This helps it set better. 2. Serve warm and cut into squares. You can also garnish with fresh herbs like parsley or chives for a pop of color and flavor. Sautéing vegetables makes a big difference. It unlocks their flavors and adds depth. Start with onions and peppers. Cook them in olive oil until soft. This step takes about five minutes. Then, add spinach and cook for two more minutes. This softens the spinach and makes it tasty. For the egg mixture, you want a smooth blend. Whisk together eggs, milk, garlic powder, and onion powder. Make sure it is well mixed. The right consistency helps the casserole set properly. Baking at the right temperature is key. Preheat your oven to 350°F. This ensures even cooking. Bake for 35 to 40 minutes. Watch for a golden top. A toothpick should come out clean when done. To avoid over-baking, set a timer. Check the casserole a few minutes early. If the edges are browning too fast, cover them with foil. Adding herbs and spices boosts flavor. Try fresh parsley, chives, or thyme. These herbs brighten the dish. You can also use garlic powder and onion powder for extra taste. Cheese makes casseroles creamy and rich.
