Preparation Steps
  1. Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking dish with cooking spray or butter.
  2. In a large skillet over medium heat, add ground breakfast sausage and sauté for 4-5 minutes until golden brown.
  3. Sauté diced onion and bell peppers in the remaining sausage drippings for 3-4 minutes until softened.
  4. In the prepared baking dish, layer quartered stale biscuits, followed by sausage, sautéed vegetables, and shredded Gruyère cheese.
  5. Whisk together eggs, half and half, kosher salt, and black pepper in a medium bowl until smooth.
  6. Pour the creamy egg mixture over the layered ingredients in the baking dish.
  7. Allow the casserole to rest at room temperature for 30 minutes or refrigerate overnight.
  8. Bake for 35-40 minutes, until the center jiggles slightly but is set, and the top is golden brown.
  9. Let the casserole cool for about 5 minutes before slicing and serving.
