Ingredients:
- 1 pound breakfast sausage (you can use mild, spicy, or Italian sausage for a different flavor profile)
- 6 large eggs
- 1 cup milk (whole milk is best for richness, but 2% will also work)
- 1 cup shredded cheddar cheese (or your favorite cheese blend like Monterey Jack or a Mexican blend)
- 2 cups bread cubes (day-old bread works wonderfully for this; you can also use croutons or even broken pieces of toast)
- ½ teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon garlic powder
- ¼ teaspoon smoked paprika (this adds a lovely subtle smoky depth)
- ½ cup diced bell peppers (any color will do – red, yellow, or green add sweetness and visual appeal)
- ½ cup chopped spinach (fresh or frozen and thawed; if using frozen, be sure to squeeze out excess moisture)
- ¼ cup diced onions (yellow or white onions work well)
Getting Started: Preheating and Preparing
Before we dive into the deliciousness, it’s important to get our oven ready and our pan prepared. Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). This moderate temperature ensures the casserole cooks through evenly without burning the top. While the oven is heating, take a moment to lightly grease a 9×13 inch baking dish. You can use butter, cooking spray, or a bit of oil to prevent the casserole from sticking, which will make serving much easier.
Step 1: Browning the Sausage and Sautéing Aromatics
Let’s start with the savory foundation of our Easy Sausage and Egg Casserole. In a large skillet, crumble the breakfast sausage. Cook it over medium heat, breaking it up with a spoon as it browns. Continue cooking until the sausage is fully cooked through and no pink remains. Once the sausage is browned, use a slotted spoon to transfer it to a paper towel-lined plate to drain off any excess grease. Don’t discard all that flavorful sausage fat just yet! If you’re using the optional diced onions and bell peppers, you can add them directly to the same skillet with a tablespoon or two of the reserved sausage drippings (or a little bit of cooking oil if there’s not much fat). Sauté the onions and peppers over medium heat for about 5-7 minutes, or until they begin to soften and become slightly translucent. This step builds a layer of flavor and ensures the vegetables are tender in the final casserole. If you’re adding spinach, you can sauté it briefly with the onions and peppers until it wilts, or stir it in raw later if you prefer a slightly fresher texture. Once the vegetables are softened, remove the skillet from the heat.
Step 2: Combining the Base Ingredients
Now it’s time to bring everything together. In a large mixing bowl, add the browned and drained sausage. If you sautéed your vegetables, add them to the bowl as well. Next, add your optional bread cubes. If you’re using them, gently toss everything together to distribute the sausage and vegetables evenly amongst the bread. If you’re not using bread cubes, that’s perfectly fine; the casserole will still be delicious and a bit more egg-forward. Now, in a separate medium bowl, whisk together the 6 large eggs and the 1 cup of milk. This is your liquid binder that will hold the casserole together. Add the ½ teaspoon of salt, ½ teaspoon of black pepper, ½ teaspoon of garlic powder, and ¼ teaspoon of smoked paprika to the egg and milk mixture. Whisk everything thoroughly until it’s well combined and slightly frothy. This seasoning blend is designed to complement the savory sausage and cheesy goodness.
Step 3: Assembling the Casserole
With all our components ready, we can now assemble the Easy Sausage and Egg Casserole. Pour the egg and milk mixture evenly over the sausage, vegetables, and bread cubes (if using) in the large mixing bowl. Gently stir everything to coat. You want to ensure that all the ingredients are moistened by the egg mixture. Next, add the 1 cup of shredded cheddar cheese to the bowl. Again, gently stir to distribute the cheese throughout the mixture. You can reserve a little bit of cheese to sprinkle on top before baking if you like an extra cheesy crust. Carefully pour the entire mixture from the bowl into your prepared 9×13 inch baking dish. Spread it out evenly to ensure consistent cooking. Don’t worry if it looks a little full; it will settle as it bakes.
Step 4: Baking to Golden Perfection
Place the assembled casserole into your preheated 350-degree Fahrenheit oven. Bake for approximately 40-50 minutes. The exact baking time can vary depending on your oven and how thick your casserole is. You’ll know it’s done when the eggs are set and the casserole is golden brown around the edges. To check for doneness, you can insert a knife or a toothpick into the center; it should come out clean. If you find the top is browning too quickly before the center is set, you can loosely tent the baking dish with aluminum foil for the last 10-15 minutes of baking. This will help the casserole cook through without burning the top.
Step 5: Resting and Serving
Once your Easy Sausage and Egg Casserole is out of the oven, it’s crucial to let it rest for at least 10 minutes before slicing and serving. This resting period allows the casserole to firm up, making it much easier to cut into neat portions. If you try to slice it too soon, it might be too runny. The aroma filling your kitchen at this point is sure to be irresistible! You can serve this hearty casserole on its own for a complete breakfast or brunch, or pair it with a side of fresh fruit or toast. It’s also a fantastic make-ahead meal; you can assemble it the night before and bake it in the morning, just adding a few extra minutes to the baking time. Enjoy every delicious bite!
