For the Biscuits:

  • 2 cups all-purpose flour
  • 2 teaspoons baking powder
  • 1/2 teaspoon salt
  • 1/2 cup (1 stick) cold unsalted butter, cubed
  • 3/4 cup buttermilk (or milk with 1 tablespoon vinegar added)
  • For the Filling:
  • 1 tablespoon olive oil
  • 1 medium onion, diced
  • 1 green bell pepper, diced
  • 8 ounces breakfast sausage, cooked and crumbled
  • 8 large eggs, whisked
  • 1 cup shredded cheddar cheese
  • 1/2 cup chopped fresh spinach (or other greens)
  • 1/2 teaspoon dried thyme
  • 1/4 teaspoon black pepper
  • Salt to taste

  • Directions:

    1. Preheat oven to 400°F (200°C). Grease a 9×13 inch baking dish.
    2. Make the Biscuits:

  • In a large bowl, whisk together flour, baking powder, and salt.
  • Using a pastry cutter or your fingertips, cut the cold butter into the flour mixture until it resembles coarse crumbs.
  • Gradually stir in the buttermilk until a soft dough forms. Be careful not to overmix.
  • Turn the dough out onto a lightly floured surface and knead a few times until just combined.
  • Pat the dough into a 1/2-inch thick rectangle. Cut the dough into squares or desired shapes.
  • 3. Prepare the Filling:

  • Heat olive oil in a large skillet over medium heat. Add the onion and bell pepper, and cook until softened, about 5 minutes.
  • Add the cooked sausage and cook for another minute, breaking it up with a spoon.
  • In a separate bowl, whisk together the eggs, cheese, spinach, thyme, pepper, and salt.
  • 4. Assemble the Casserole:

  • Spread the sausage mixture evenly in the prepared baking dish.
  • Pour the egg mixture over the sausage.
  • Arrange the biscuit dough squares on top of the egg mixture.
  • 5. Bake for 25-30 minutes, or until the biscuits are golden brown and the eggs are set.
    6. Let cool slightly before serving.
