Ingredients

- 1 pound breakfast sausage (mild or spicy, your call)
- 8 large eggs
- 2 cups whole milk (or half-and-half for extra richness)
- 4 cups cubed day-old bread (French loaf or sourdough works great)
- 2 cups shredded cheddar cheese
- 1 cup diced bell pepper (any color)
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 1 teaspoon salt
- ½ teaspoon black pepper
- 1 teaspoon dried oregano or Italian seasoning
- Optional: 1 cup fresh spinach or kale (chopped)
Instructions
- Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or nonstick spray.
- Cook the sausage in a skillet over medium heat. Break it into crumbles and sauté until fully browned (about 6–8 minutes).
- Add the chopped onion, bell pepper, and garlic to the sausage. Sauté for 3–4 minutes until veggies soften. If you’re into **Brunch Casserole** upgrades, toss in spinach here.
- In a large bowl, whisk together the eggs, milk, salt, pepper, and oregano. Feel free to riff on the spices—cayenne anyone?
- Layer half of the bread cubes in the bottom of the baking dish. Sprinkle half of the cooked sausage-veg mix over the bread.
- Scatter 1 cup of cheddar cheese evenly. Then layer the remaining bread cubes and sausage mixture. Top with the last cup of cheese.
- Pour the egg-milk mixture slowly over the layers. Press down gently so the bread soaks up all that custardy goodness.
- Cover the dish with foil and bake for 30 minutes. Remove the foil and bake for another 15–20 minutes until the top turns golden and the center sets.
- Let the casserole rest for 5–10 minutes before slicing. This step keeps it together—no one likes a messy slice!
- Serve warm. Trust me, leftovers taste even better the next day.
