Prep and Cook Time:
- 15 minutes prep | 50 minutes bake | 8 hours chilling (overnight recommended)
Yield:
- Serves 8 hearty portions
Difficulty Level:
- Easy
Ingredients:
- 8 large eggs, room temperature
- 2 cups whole milk or unsweetened almond milk
- 1 teaspoon salt (adjust to taste)
- ½ teaspoon black pepper, freshly ground
- 1 cup sharp cheddar cheese, shredded
- 1 cup mozzarella cheese, shredded
- 1 cup cooked chicken sausage, sliced
- 1 large red bell pepper, diced
- 2 cups fresh spinach, roughly chopped
- 4 cups whole-grain bread cubes, slightly toasted
- 1 small yellow onion, finely chopped
- 2 cloves garlic, minced
- 1 teaspoon fresh thyme, chopped

Instructions:
- Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with olive oil or non-stick spray for perfect release.

- chill for best results: Cover tightly with foil and refrigerate for at least 4 hours or overnight. This step allows the casserole to set and flavors to meld beautifully.
- Bake uncovered for 45-50 minutes, or until the edges are golden brown and the center is set but still slightly jiggly. A toothpick inserted in the middle should come out mostly clean.
- Rest before serving: Let the casserole cool for 10 minutes; this helps it slice cleanly and enhances texture.
