How Do You Make This Breakfast Casserole?
This recipe involves simple steps and preparation to create a flavorful and satisfying dish for Father’s Day brunch.
Step 1 — Prepare the Baking Dish
Grease a 9×13-inch baking dish lightly with olive oil or cooking spray.
Step 2 — Make the Egg Mixture
In a large mixing bowl, whisk together the eggs, milk, salt, pepper, garlic powder, onion powder, and dried parsley until fully combined.
Step 3 — Add Cheese
Mix the shredded cheddar and mozzarella cheeses into the egg mixture, ensuring they are evenly distributed.
Step 4 — Sauté the Sausage and Vegetables
Heat the olive oil in a skillet over medium heat. Add the diced turkey sausage, bell peppers, and onion. Sauté for 5-7 minutes, or until the vegetables are softened and the sausage is lightly browned.

Step 5 — Layer the Casserole
Spread the cubed bread evenly across the bottom of the prepared baking dish, followed by the sautéed sausage and vegetables.
Step 6 — Pour Egg Mixture
Pour the egg and cheese mixture evenly over the bread and sausage layers, ensuring all the bread is soaked.
Step 7 — Refrigerate and Bake
Cover the dish tightly with foil and refrigerate for at least 4 hours or overnight. The next morning, preheat the oven to 375°F (190°C). Remove the casserole from the fridge and let it sit at room temperature for 20 minutes. Bake covered for 30 minutes, then uncover and bake for an additional 15-20 minutes or until the top is golden brown and set in the center.
Step 8 — Serve and Enjoy
Remove the casserole from the oven and let it rest for 5 minutes before slicing and serving.
