Ingredients for this Easy Brunch Casserole

• 1 lb ground breakfast sausage (pork or turkey)
• 6 large eggs
• 2 cups whole milk
• 1½ cups shredded sharp cheddar cheese
• 1 cup shredded mozzarella cheese
• 2 cups cubed day-old bread (French or sourdough works well)
• ½ cup chopped red bell pepper
• ½ cup chopped green onions
• 1 tsp garlic powder
• ½ tsp salt
• ½ tsp black pepper
• Optional: chopped fresh parsley for garnish

Step 1: Prepare the Ingredients

Start by preheating your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish and set it aside. In a skillet over medium heat, cook the sausage until browned and fully cooked, breaking it into crumbles as it cooks. Drain any excess fat and remove from heat.

---

Step 2: Layer the Base

Spread the cubed bread evenly in the bottom of the prepared baking dish. Then, sprinkle the cooked sausage over the bread, followed by the chopped red bell pepper and green onions. This creates a solid, flavorful base for your casserole.

---

Step 3: Mix the Egg Mixture

In a large mixing bowl, whisk together the eggs, milk, garlic powder, salt, and pepper until well combined. Stir in both the cheddar and mozzarella cheeses, saving a small handful of cheddar for topping.

---

Step 4: Combine and Let It Rest

Pour the egg mixture evenly over the layered ingredients in the dish. Use a spatula or spoon to gently press everything down, ensuring the bread soaks up the liquid. Let the mixture sit for about 10–15 minutes to absorb the flavors.

---

Step 5: Bake to Perfection

Sprinkle the remaining cheddar cheese on top and place the dish in the preheated oven. Bake uncovered for 45–50 minutes, or until the top is golden and the center is set. A knife inserted in the middle should come out clean.

Step 6: Rest, Garnish & Serve

Once baked, let the casserole rest for 5–10 minutes before slicing. Garnish with fresh parsley or extra green onions if desired. Serve warm and enjoy the comforting layers of flavor in every bite.

To reheat, microwave individual servings for 1–2 minutes or warm in a 350°F (175°C) oven until heated through. If frozen, thaw overnight in the fridge before reheating.
