Ingredients
  

  • Bisquick (or similar baking mix) – 1 cup
  • Large eggs – 6
  • Milk – 1 cup (whole or 2%)
  • Breakfast sausage – 1 pound (pork or turkey; mild or hot)
  • Shredded cheddar cheese – 1½ cups (or a blend)
  • Onion – 1 small, diced
  • Red or green bell pepper – 1 small, diced
  • Garlic – 2 cloves, minced (optional)
  • Salt – ½ teaspoon (adjust to taste)
  • Black pepper – ½ teaspoon
  • Paprika or smoked paprika – ½ teaspoon (optional)
  • Cooking spray or butter – for greasing the dish

Instructions
 

  • Preheat and prep. Heat the oven to 375°F (190°C). Grease a 9x13-inch baking dish with cooking spray or butter.
  • Cook the sausage. In a large skillet over medium heat, crumble and cook the sausage until browned, about 6–8 minutes. Drain excess fat. Add onion, pepper, and garlic; cook 3–4 minutes until softened.
  • Layer the fillings. Spread the sausage and veggie mixture evenly in the baking dish. Sprinkle 1 cup of the shredded cheese over the top.
  • Mix the batter. In a bowl, whisk eggs, milk, Bisquick, salt, pepper, and paprika until smooth. A few tiny lumps are fine—don’t overmix.
  • Pour and top. Pour the egg mixture evenly over the sausage and cheese. Sprinkle the remaining ½ cup cheese on top.
  • Bake. Bake for 28–35 minutes, until the center is set and the top is golden. A knife inserted near the center should come out mostly clean.
  • Rest and serve. Let it rest 5–10 minutes before slicing. This helps it set and makes cleaner squares. Serve warm with hot sauce or a side of fruit.
