Step‑by‑Step Instructions for Sausage and Spinach Breakfast Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C). While the oven heats up, grab a 9×13 baking dish and spray it lightly with oil to prevent sticking. This preparation sets the stage for your Sausage and Spinach Breakfast Casserole, ensuring a deliciously golden finish.
Step 2: Brown the Sausage
In a large skillet over medium-high heat, add your sausage of choice. Cook it for about 5–7 minutes, breaking it apart with a spatula until it’s slightly browned and cooked through. The savory aroma will fill your kitchen, promising a hearty casserole as it browns beautifully. Once done, transfer the sausage to your prepared baking dish.
Step 3: Sauté the Vegetables
In the same skillet, drizzle in 2 teaspoons of olive oil. Add the diced onions, minced garlic, spinach, and both green and red bell peppers. Sauté the mixture for 6–7 minutes, stirring occasionally until the spinach wilts and the vegetables soften. Season with salt and pepper to taste, adding a layer of flavor to your Sausage and Spinach Breakfast Casserole.
Step 4: Layer the Vegetables
Once the vegetable mixture is cooked, evenly layer it over the sausage in your baking dish. This colorful blend will provide ample flavor and nutrition to the casserole. Using a spatula, spread the vegetables gently to ensure they are well distributed, making for an enticing and vibrant breakfast.
Step 5: Whisk the Egg Mixture
In a large bowl, crack the 12 eggs and whisk them together with ½ cup of milk and the grated cheese. Incorporate the paprika, garlic powder, onion powder, dried dill, dried rosemary, red pepper flakes, and season with salt and black pepper. This egg mixture acts as the binding agent for your Sausage and Spinach Breakfast Casserole, combining all elements into one cohesive dish.
Step 6: Combine Ingredients
Pour the egg mixture over the sausage and vegetable layers in the baking dish. Make sure the eggs cover everything evenly, soaking into the layers beneath for a homogenous texture. This process transforms the ingredients into a deliciously firm yet fluffy casserole as it cooks.
Step 7: Add More Cheese
Sprinkle the remaining ½ cup of grated cheese on top of the casserole. This additional layer of cheese will melt beautifully, creating a deliciously gooey topping. It’s perfect for that comforting finish, making your Sausage and Spinach Breakfast Casserole irresistible.
Step 8: Chill and Set
Cover the baking dish with plastic wrap and refrigerate for at least 2 hours, or overnight if planning ahead. This step allows the flavors to meld beautifully and gives the casserole time to set, which will enhance its overall texture and taste.
Step 9: Bake the Casserole
Once chilled, remove the plastic wrap and place the casserole in the preheated oven. Bake for approximately 45 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out clean. The mouthwatering aroma will fill your home, signaling it’s almost breakfast time!
Step 10: Cool and Serve
Allow the Sausage and Spinach Breakfast Casserole to cool for about 10 minutes before slicing it into squares. This resting time helps with the serving process, making sure each piece holds its shape nicely. Enjoy your hearty breakfast with family or friends!
