Let’s Make it Together
Preheat your oven: Start by preheating your oven to 375°F (190°C). This ensures even cooking throughout your casserole.
Prepare the baking dish: Grease a 9×13 inch baking dish with nonstick spray or butter. This step prevents sticking and makes cleanup easier.
Cook the sausage: In a skillet over medium heat, brown the breakfast sausage until it’s fully cooked and crumbly. Drain excess fat if needed, then set aside.
Sauté vegetables: In the same skillet, add chopped onions and bell peppers. Cook them until they’re tender and fragrant, about 5-7 minutes.
Combine ingredients: In a large bowl, whisk together eggs and milk. Stir in cooked sausage, sautéed veggies, salt, pepper, and half of the shredded cheese.
Layer it up: Spread hashbrowns evenly across the bottom of your prepared baking dish. Pour egg mixture over the top, ensuring even coverage.
Add cheese topping: Sprinkle remaining shredded cheese over everything like you’re creating an edible masterpiece—because you are!
Bake: Place in preheated oven and bake for 35-40 minutes or until the top is golden brown and bubbly. You’ll know it’s done when it puffs up beautifully.
Serve hot: Allow cooling for about 5 minutes before slicing into squares. Serve warm alongside fresh fruit or pastries if you’re feeling fancy!
With these steps complete, you’ll have created a breakfast casserole with hashbrowns that not only feeds but also delights! Enjoy every delicious bite!
