Preparation Steps
Greasing the Baking Dish
First off, grease a 9×13-inch (3–4-quart) oven-safe dish. This step is important because it helps the casserole come out easily and prevents sticking. Once greased, arrange the bread cubes in an even layer at the bottom of the dish. This base will soak up all the delicious flavors!
Cooking the Sausage and Vegetables
Next, grab a large skillet and heat the olive oil over medium heat. Add the sausage, using a wooden spoon or spatula to break it apart as it cooks. If you’re feeling fancy, sprinkle in some dried rosemary or Italian seasoning. You’ll want to keep cooking until the sausage is nicely browned. As it cooks, incorporate the onions, garlic, bell peppers, mushrooms, and spinach. Cook everything together until the vegetables soften, turning this mixture into a flavor-packed filling.
Layering the Ingredients
Now, it’s time to build your layers! Spread that beautifully cooked sausage and vegetable mixture evenly over the bread cubes in the baking dish. This step ensures that every bite will be a perfect combination of ingredients.
Preparing the Egg Mixture
In a separate bowl, whisk together the eggs, salt, pepper, milk, and cheese. You’ll want to pour this creamy goodness over the sausage and vegetable layer. To enhance the flavors, you can sprinkle a little more salt and pepper on top.
Refrigerating Before Baking
This step is where the make-ahead magic happens! Cover the casserole with plastic wrap or aluminum foil and refrigerate it for at least 30 minutes, or up to 24 hours if you’re prepping ahead. Just remember to let it sit at room temperature for 10–15 minutes after taking it out of the fridge.
Baking the Casserole
When you’re ready to enjoy your Easy Make-Ahead Breakfast Casserole, preheat the oven to 375°F (191°C). Bake the casserole uncovered for about 40–45 minutes. You know it’s done when the top is golden and a toothpick inserted in the center comes out clean.
Serving the Casserole
Before cutting it, allow the casserole to cool for about 10 minutes. This waiting period helps it set a little better. You can garnish it with some green onions or parsley for a pop of color if you’d like.
Serving Suggestions
To complement your breakfast casserole, consider serving it alongside fresh fruit, yogurt, or a light salad. This combination adds a nice balance to your meal and gives everyone tasty options.
Tips for Success
- Using day-old bread will give you a better texture. It soaks up the egg mixture nicely without getting soggy.
- Don’t hesitate to experiment! If there are veggies you prefer or have on hand, feel free to give them a go.
Variations
