Breakfast Casserole with Bisquick

If you’ve ever had the original Betty Crocker recipe, you know how incredibly delicious Bisquick Breakfast Casserole is.

After making it and enjoying it so many times, I ended up with a variation that my family loves even more. I knew I had to share it with all of you! Our recipe uses a few more eggs and has some salt.

If you love the flavors in biscuits and gravy, you’ll love this recipe. Also – if you love gravy for breakfast, be sure to check out the Best Sausage Gravy recipe!

Sometimes we have family gatherings that involve making breakfast for 15 people, and I’m always I’m always looking for fun and easy things to make for a crowd.

That’s why I love this casserole – it makes feeding everyone meat, potatoes, and eggs surprisingly easy.

My favorite part is that the whole thing is served hot – I don’t have to worry about the eggs cooling down too much while the potatoes finish cooking or anything like that.

I also love that you can make this breakfast casserole a day ahead, and just reheat it in the morning. It’s so filling and delicious – it’s really just the best brunch food!

Try serving it with a dash of hot sauce and a side dish of cheese grits, some twisted bacon, Ambrosia salad, or fruit salad.

Pork Sausage: Use your favorite raw sausage, just so long as you’re able to crumble it. Spicy, mild, Italian, and Jimmy Dean Sausage all work.

You could also use any of these cooked meats: bacon, diced ham cubes, or ground beef.

Red Bell Pepper and Yellow Onion: These vegetables add flavor and a variation in the texture. They really help to break up the casserole so that it feels more substantial than just meat and potatoes.

If you like a little spice, jalapeños or green chilies would be a great addition. Spinach that’s been cooked and thoroughly squeezed (to get rid of excess moisture) is also a great way to add more vegetables in!

Hash Browns: Using frozen hash browns keeps it super easy. It’s a great starch to bulk it up enough to feed more people without extra work.

If you can’t find hash browns, you could probably use tater tots.

Cheddar Cheese: Cheese adds flavor, that awesome ooey gooey melted texture, and it’s also a binder to hold the sausage casserole together. You could also use mozzarella cheese if you’d prefer.

Just be sure to use freshly shredded cheese. The cheese that’s pre-shredded is coated in an anti-caking agent, which stops it from melting well when you bake it.

Eggs: These are what makes it a breakfast casserole, and they add binding power to hold it together.

Whole Milk: This makes it creamy without being heavy. It’s also the liquid that will combine with the Bisquick to make the dish perfectly fluffy, but still solid enough to cut into clean slices.

I prefer to use whole milk in baking because it has a higher fat content, which means there’s less of a risk of it breaking or curdling.

Bisquick: This is what makes the casserole light and fluffy, and it stops the eggs from being too dense after baking. It also stops the eggs from being soggy.

Salt and Pepper: These are the seasonings in the dish. If there are other spices or herbs that you love, feel free to add them in!

Can You Freeze Bisquick Breakfast Casserole

Yes! You can freeze the baked breakfast casserole for up to 2 months. Just be sure to wrap it tightly before you freeze it so that it doesn’t get freezer burn.

To reheat it, let it thaw overnight in the fridge. Then bake it for about 20 minutes at 350 F, or until it’s warmed through.

Bisquick breakfast casserole is loaded with eggs, hash browns, and crumbled sausage. It’s creamy, light and fluffy, and so flavorful!

Prep Time 10 minutes
Cook Time 45 minutes
Total Time 55 minutes


  • 1 1/2 pounds pork sausage
  • 1 medium red bell pepper (diced, 3/4 cup)
  • 1 medium yellow onion (diced, 1 cup)
  • 3 cups frozen hash brown potatoes
  • 2 cups freshly shredded sharp cheddar cheese*
  • 6 large eggs
  • 2 cups whole milk
  • 1 teaspoon fine sea salt
  • 1/2 teaspoon ground black pepper
  • 1 cup Bisquick


  1. Preheat the oven to 400 F (204 C). Grease a 13 x 9 casserole dish and set it to the side.
  2. Heat a large nonstick skillet over medium-high heat. Once hot, add the sausage, red bell pepper, and onion. Cook until the sausage is no longer pink (about 10 minutes). Turn off the heat and drain off any grease.
  3. Add the hash browns and 1 1/2 cups of the shredded cheese to the sausage mixture. Mix together and pour into the greased casserole dish.
  4. In a medium mixing bowl, whisk the eggs, milk, salt, and pepper together. Add in the Bisquick and whisk until well combined, then pour the Bisquick mixture over the sausage and potatoes.
  5. Place the uncovered casserole into the preheated oven and bake for 40 - 45 minutes (or until a toothpick inserted in the center comes out clean). Add the rest of the shredded cheese and put it back into the oven until the cheese is melted (about another 2 minutes).


*It’s important to use freshly shredded cheese because it melts better than pre-shredded cheese does. Store bought shredded cheese is coated in an anti-caking agent to stop the shreds from sticking together, but it also stops the cheese from melting smoothly.
