Pin RecipeThe Best Bisquick Breakfast Casserole Recipe
I absolutely love breakfast casseroles like my Easy Breakfast Casserole, Vegetarian Breakfast Casserole, and this Bisquick Breakfast Casserole! Not only are they delicious, but they’re also easy recipes to make and great for feeding a crowd. Serve a slice of breakfast casserole with a fresh fruit salad or a Blueberry Protein Smoothie and your morning meal will be complete!
This Bisquick breakfast casserole recipe is one of my all-time favorite quick breakfast ideas. The casserole starts by cooking ground breakfast sausage with bell pepper and onion. Then, we add hash brown potatoes and mix in some cheddar cheese. You always need cheese in a breakfast casserole!
The best part of this savory breakfast casserole is the Bisquick baking mix that I whisk together with milk, eggs, and a bit of maple syrup. We pour the sweet pancake mix over the savory ingredients to give this breakfast dish the perfect blend of flavors.
Finally, the casserole goes into the oven to bake. In, a matter of minutes, you’ll have a delicious breakfast ready to serve! This morning casserole is perfect for holidays, special occasions, or just to make for your family on a weekday.
Ingredients for Bisquick Breakfast Casserole
To print: see recipe card below
- 1 1/2 pounds ground breakfast sausage – Any type of ground sausage will work for this sausage and cheese casserole.
- 1 red bell pepper – Feel free to use red bell pepper, orange bell pepper, or green bell pepper!
- 1 Onion
- 3 cups frozen hashbrown potatoes
- 2 cups shredded cheddar cheese – For the best results, buy a block of cheese and grate it yourself.
- 1 cup Bisquick baking mix – Any brand of pancake mix will work. You can even try making your own pancake mix using my homemade pancake mix recipe.
- 4 eggs
- 2 cups whole milk
- 2 Tablespoons maple syrup – Use real maple syrup, not imitation syrup.
- 1 teaspoon salt
- 1/2 teaspoon ground black pepper
Variations
- Skip the sausage for a vegetarian breakfast casserole. In this case, I recommend doubling the bell peppers or adding more veggies like sautéd mushrooms or baby spinach.
- Replace the breakfast sausage with cooked, crumbled bacon.
- Use shredded pepper jack cheese or a Mexican cheese blend in place of the sharp cheddar cheese.

- Prepare: Preheat the oven to 400 degrees Fahrenheit. Grease a 9×13 baking dish with nonstick cooking spray, and set it aside.
- Cook the sausage: Heat a large skillet over medium-high heat. Add the sausage, pepper, and onion. Cook for about ten minutes, breaking the meat up as it cooks. Continue to cook until the meat is no longer pink and the veggies are soft.
- Finish the filling: Remove the skillet from the heat, and stir in the hash browns and 1 1/2 cups of shredded cheese. Spread the sausage mixture into the casserole dish, spreading it out in an even layer.
- Make the pancake mix: In a large bowl, whisk the Bisquick mix, eggs, milk, maple syrup, salt, and pepper. Pour the mixture evenly over the casserole filling.
- Bake the casserole: Transfer the casserole to the oven, and bake for 40 minutes. The casserole will be golden brown and a knife inserted into the center will come out clean.
- Top: Sprinkle the remaining 1/2 cup of cheese on top. Return the casserole to the oven, and bake for three to four minutes to melt the cheese. Slice, and serve hot!
Serving Suggestions
This Bisquick breakfast casserole recipe is fantastic on its own. However, it also pairs well with a light, fruity side dish like a tropical smoothie or fruit and grain smoothie bowl.
Or, serve it with some avocado toast or salmon toast for a more filling side dish. You can’t go wrong with a cup of whipped coffee next to your breakfast casserole, either!
How to Store + Freeze Bisquick Breakfast Casserole
- Allow the casserole to cool completely. Then cover the baking dish with plastic wrap and aluminum foil, or transfer the casserole to an airtight container.
- Store in the fridge for up to three to four days, or freeze for up to two months.
- Thaw the frozen casserole in the fridge overnight. Then, reheat in the oven for ten minutes or until the center is hot. Or, warm individual servings in 30-second increments in the microwave.
Quick Tip
The maple syrup added to the pancake mix gives the dish a subtle, sweet taste that is really irresistible. However, you can skip the syrup if you prefer a more savory casserole. Or, you can use honey in place of syrup for a new twist on this easy breakfast recipe!
