Let’s Make it Together
Preheat Your Oven: Start by preheating your oven to 375°F (190°C). Get those cooking vibes going while you prepare the other ingredients.
Prepare Your Baking Dish: Grease a 9×13 inch baking dish with nonstick spray, ensuring every nook and cranny is covered so nothing sticks later.
Layer the Hashbrowns: Spread the hashbrowns evenly across the bottom of your baking dish. Use frozen ones for convenience or freshly grated if you’re feeling adventurous.
Add Eggs and Mix-ins: In a bowl, whisk together the eggs with salt and pepper until combined. Fold in bell peppers, cooked sausage or bacon if using, and half of the cheese.
Pour Over Hashbrowns: Carefully pour the egg mixture over the layer of hashbrowns. Let it spread out nicely – we want even coverage here!
Bake Until Perfectly Golden: Place your casserole in the oven and bake for about 35-40 minutes until set in the middle and golden brown on top. Keep an eye out for that delightful aroma!
Once it’s done baking, let it cool slightly before slicing into squares. Every bite will be filled with cheesy goodness mixed with crispy bits from the hashbrowns, leaving everyone wanting just one more piece!
