How to Make Southwestern Breakfast Casserole: 7 Flavors to Savor Recipe
Step 1: Preheat and Prepare
Start by setting your oven to 350 degrees Fahrenheit (175 degrees Celsius) so that it’s perfectly heated when your casserole is ready to go in. Grease your baking dish lightly to prevent sticking and ensure an easy release once it’s baked.
Step 2: Whisk the Egg Mixture
In a large bowl, whisk together the eggs, milk, salt, and pepper vigorously until you have a smooth mixture. This will be the creamy custard that holds the casserole together.
Step 3: Fold in the Flavorful Ingredients
Gently stir in the diced potatoes, cooked sausage, shredded cheese, diced bell peppers, onions, and chopped cilantro. Mixing them evenly ensures every bite bursts with the seven wonderful flavors.
Step 4: Transfer to Baking Dish
Pour the combined mixture into your prepared baking dish, spreading it out evenly. This helps the casserole cook uniformly and look as inviting as it tastes.
Step 5: Bake Until Set
Bake the casserole in the oven for 30 to 35 minutes, or until the eggs are fully set and the top is golden and slightly puffed. This step transforms your ingredients into a warm, comforting dish.
Step 6: Cool and Serve
Allow the casserole to cool for a few minutes before slicing. This resting time helps it firm up and makes serving cleaner and easier, while preserving its inviting texture.
