How to Make This Easy Sausage and Egg Casserole Recipe
Let’s dive into how to bring this breakfast dream to life, I have a few tricks up my sleeve that will help you make your the best Easy Sausage and Egg Casserole ever.
- 1. Preheat and Prep: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish with melted butter.
- 2. Brown the Sausage: In a skillet, brown the sausage over medium heat until fully cooked, breaking it apart with a spoon as it cooks. Drain off any excess grease.
- 3. Mix the Wet Ingredients: In a large bowl, whisk together the eggs, milk, dry mustard, salt, and pepper.
- 4. Assemble the Casserole: Place the cubed bread in the buttered baking dish. Sprinkle the cooked sausage, chopped onion, and green pepper (if using) evenly over the bread.
- 5. Pour the Egg Mixture: Pour the egg mixture over the sausage and bread. Gently press down to ensure all the bread is soaked. Sprinkle the shredded cheese over the top. At this step, feel free to add red pepper flakes onto the top to spice it up!
- 6. Bake: Bake in the preheated oven for 30 to 40 minutes, or until the casserole is golden brown and set. The secret is to let rest for 10 minutes after it comes out of the oven.
- 7. Let cool before serving.
