Step‑by‑Step Instructions for Savory Egg Sausage Bread Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While it warms up, take a generous amount of cooking spray or butter to grease a 9x13-inch baking dish, ensuring all edges are coated well to prevent any sticking. This is the foundational step that will lead to a perfectly baked Savory Egg Sausage Bread Casserole.
Step 2: Cube the Bread
Next, take your stale bread and cut it into bite-sized cubes, about one-inch large. Layer these cubes evenly in the greased baking dish. You want to create a solid base that absorbs the egg mixture without becoming soggy, so spread them out nicely for even coverage.
Step 3: Cook the Sausage and Vegetables
In a large skillet over medium heat, add your breakfast sausage and cook it until it's browned and fully cooked through, which should take about 5-7 minutes. Once browned, toss in the chopped mushrooms and spinach, cooking for an additional 3-4 minutes until the veggies are tender and the spinach has wilted. This step builds the delicious flavor profile of your casserole.
Step 4: Whisk the Egg Mixture
While the sausage and veggies are cooking, grab a mixing bowl to whisk together the eggs, milk, and sharp cheddar cheese. As you whisk, take care to blend them until fully combined, and season with salt and pepper. The resulting mixture should be smooth and creamy, ready to bring everything together in the Savory Egg Sausage Bread Casserole.
Step 5: Combine and Pour
After the sausage and veggies have cooled slightly, gently mix them into the prepared egg mixture. Stir until everything is well coated. Then, pour this flavorful blend evenly over the layered bread cubes in the baking dish, ensuring every piece of bread is soaked to absorb the delightful flavors.
Step 6: Bake the Casserole
Now it’s time to bake! Place the casserole in the preheated oven and let it bake for approximately 50 minutes. You’ll know it’s done when the center is set and the top is beautifully golden brown. The delightful aroma of the Savory Egg Sausage Bread Casserole will fill your kitchen, tempting everyone nearby.
Step 7: Cool and Serve
Once baked, remove the casserole from the oven and let it cool for about 10-15 minutes. This cooling period allows it to set, making slicing easier. You’ll be left with a hearty, golden delight that can be served warm for family gatherings or cozy weekend brunches.
