Let’s Make It Together
Preheat oven to 375°F (190°C). Lightly grease a 9×13 baking dish with cooking spray. Spread the hashbrowns evenly across the bottom of the dish. This layer should be nice and crispy!
Sauté Your Vegetables: In a skillet over medium heat, add a splash of oil and toss in your diced onion and bell peppers. Cook until just tender and fragrant—about five minutes will do. Let those veggies work their magic!
Prepare Egg Mixture: In a mixing bowl, whisk together eggs and milk until frothy. Season generously with salt, pepper, garlic powder, and paprika for that flavor kick. Don’t forget—this is where you can express yourself!
Add Your Meats: Fold in cooked sausage or bacon into the egg mixture gently. This step ensures every bite has that savory goodness. Trust me; this is where dreams come true.
Combine Everything: Pour the egg mixture evenly over the hashbrowns in your baking dish. Sprinkle cheddar cheese on top like you’re granting wishes! Bake uncovered in preheated oven for about 35-40 minutes or until set and golden brown.
Cool Down & Serve: Once out of the oven, let it cool slightly before slicing into squares. Serve warm at brunch or enjoy leftovers throughout the week!
And there you have it: an unforgettable breakfast casserole with hashbrowns that will bring smiles around your table!
