Prepare the Baking Dish
Next, you’ll want to prepare your baking dish. Grease a 9×13-inch or any 3–4-quart oven-safe dish with a little oil or cooking spray. This step ensures that your casserole won’t stick and makes cleaning up a breeze later on.
Cook the Sausage and Vegetables
Start heating your olive oil in a large skillet over medium heat. Add your ground beef sausage and, if you like, some dried rosemary or Italian seasoning. As you cook the sausage, break it into bite-sized pieces. Once it begins to brown, toss in your onion, garlic, bell peppers, mushrooms, and spinach. This medley should cook for about 5–6 minutes until everything is softened but not mushy. The smell will be irresistible!
Assemble the Casserole Layers
Spread your cooked sausage and veggie mixture evenly over the bread cubes in your prepared baking dish. This layer of goodness sets the foundation for your easy make-ahead breakfast casserole.
Prepare the Egg Mixture
In a separate bowl, whisk together the eggs, milk (or half-and-half), and add a sprinkle of salt and pepper. Don’t forget to stir in your shredded cheddar cheese! This creamy mixture brings everything together beautifully. Pour it evenly over your sausage and vegetable layers.
Refrigerate for Later Use
Now, cover your casserole with plastic wrap or aluminum foil. This dish can sit in the fridge for at least 30 minutes or up to 24 hours — perfect for busy mornings! When you’re ready to bake, let it sit at room temperature for about 10–15 minutes as the oven preheats, which helps ensure even cooking.
And there you have it — a structured yet friendly guide to whipping up an easy make-ahead breakfast casserole. Not only will this save you time during the week, but it also offers a delicious homemade breakfast that you can customize any way you like! Enjoy!
