Layers of sausage, eggs, cheese, and bread baked into a hearty, golden slab — the kind of dish that feeds a crowd with almost no morning effort.

Ingredients

8 Servings
  • 1 lbbreakfast sausage(bulk, not links)
  • 1 smallyellow onion(diced)
  • 1 mediumgreen bell pepper(diced)
  • 6 sliceswhite sandwich bread(cut into 1-inch cubes)
  • 8large eggs
  • 2 cupswhole milk
  • 1 tspdry mustard
  • ½ tspgarlic powder
  • ½ tspkosher salt
  • ¼ tspblack pepper
  • 2 cupsshredded cheddar cheese(divided)

Method

  1. 01

    Preheat the oven to 350 °F. Grease a 9×13-inch baking dish with butter or nonstick spray.

  2. 02

    Cook the 1 lb breakfast sausage in a large skillet over medium-high heat, breaking it into crumbles, until no pink remains, about 6–8 minutes. Transfer to a paper-towel-lined plate.

  3. 03

    Drain all but 1 tbsp of fat from the skillet. Add the diced small yellow onion and diced medium green bell pepper and cook over medium heat until softened, about 4 minutes.

  4. 04

    Spread the 6 slices of cubed bread evenly across the bottom of the prepared baking dish.

  5. 05

    Scatter the cooked sausage, onion, and bell pepper over the bread cubes.

  6. 06

    Sprinkle 1 ½ cups of the shredded cheddar cheese evenly over the sausage layer, reserving the remaining ½ cups for topping.

  7. 07

    In a large bowl, whisk together the 8 large eggs, 2 cups whole milk, 1 tsp dry mustard, ½ tsp garlic powder, ½ tsp kosher salt, and ¼ tsp black pepper until fully combined.

  8. 08

    Pour the egg mixture slowly and evenly over the entire casserole so the bread absorbs it.

  9. 09

    Scatter the reserved ½ cups shredded cheddar cheese over the top.

  10. 10

    Bake uncovered at 350 °F for 45–55 minutes, until the center is set (a knife inserted in the middle comes out clean) and the top is golden brown.

  11. 11

    Let the casserole rest for 5 minutes before slicing and serving.
