  • 2 cups of milk: This liquid gold melds with the eggs, creating a custard-like texture that’s both comforting and luxurious.
  • 2 cups of Bisquick baking mix: The magic dust that transforms the liquid ensemble into a fluffy, golden-brown crust, holding our creation together with just the right amount of heartiness.
  • 1 pound of breakfast sausage: Carefully browned to perfection, its savory notes dance through the casserole, offering a delightful contrast to the creamy backdrop.
  • 1 cup of shredded cheddar cheese: A cascade of melty, gooey goodness that strings along every forkful, bringing with it the joy of indulgence.

  • 1 cup of diced onions: These humble bulbs, when sautéed, unfold layers of sweetness and depth, embedding each bite with a subtle warmth.
  • 1 cup of diced tomatoes: Fresh, juicy, and bursting with a slight tang, they sprinkle the dish with a hint of acidity and a wealth of vitamins.

How to Make Bisquick Breakfast Casserole Recipe

  • Preheat Your Oven: Begin by heating your oven to 375°F (190°C), setting the stage for a perfectly baked casserole.
  • Cook the Sausage: In a large skillet over medium heat, crumble and brown the breakfast sausage until fully cooked. Once done, remove the sausage with a slotted spoon, leaving behind any rendered fat for cooking the vegetables.
  • Sauté the Vegetables: In the same skillet, add the diced onions and bell peppers. Sauté until the onions become translucent and the peppers soften, infusing them with the flavorful sausage remnants.
  • Prepare the Egg Mixture: In a large mixing bowl, whisk together the eggs, milk, salt, and black pepper until thoroughly combined. This mixture will form the custard base of your casserole.
  • Layer the Ingredients: In a greased 9×13 inch baking dish, evenly spread the cooked sausage. Top with the sautéed onions and peppers, diced tomatoes, and finally, sprinkle the shredded cheddar cheese evenly over the top.
  • Add the Bisquick Mix: Gently pour the egg mixture over the layered ingredients in the baking dish. With a fork, slightly whisk in the Bisquick baking mix to ensure it’s evenly distributed throughout the egg mixture, avoiding any large clumps.
  • Bake to Perfection: Place the baking dish in the preheated oven and bake for 35-40 minutes, or until the top is golden brown and a knife inserted into the center comes out clean. The casserole should be set but slightly jiggly, indicating it’s perfectly cooked.

Serving Instructions

Once your Bisquick Breakfast Casserole is baked to a golden perfection, let it sit for about 5 minutes before slicing. This brief rest allows the casserole to firm up, making it easier to cut into beautiful, serving-sized squares. Serve warm, perhaps with a side of fresh fruit or a light salad to balance the hearty flavors. If you like, a drizzle of hot sauce or a dollop of sour cream can add an extra layer of flavor.

Storage and Freezing Instructions


If you find yourself with leftovers, or if you’re planning ahead, storing the Bisquick Breakfast Casserole is straightforward. Allow the casserole to cool completely, then cover the dish with foil or transfer slices into an airtight container. Stored in the refrigerator, it will keep well for up to 3 days. To reheat, simply cover with foil and warm in a 350°F (175°C) oven until heated through, or microwave individual servings for a quick option.


For longer preservation, this casserole freezes beautifully. To freeze, cool the casserole completely and cut it into portions. Wrap each portion tightly with plastic wrap, then again with foil to prevent freezer burn. Stored in the freezer, it will maintain its best quality for up to 2 months. When ready to enjoy, thaw overnight in the refrigerator and reheat as recommended above. This makes for an excellent make-ahead meal that can be enjoyed any day of the week with minimal preparation.
