RECIPE INGREDIENTS
You’ll need the following ingredients to make this delicious Bisquick Breakfast Casserole Recipe:
INGREDIENT NOTES
Breakfast Sausage: Bulk breakfast sausage (without casings) is best for this recipe. Jennie-O sells a bulk turkey breakfast sausage that I love if you want to go a bit leaner. Try maple breakfast sausage for a little more sweetness.
Milk: I have made this recipe with low-fat milk, whole milk, and half and half. They all work. Whole milk is my top choice, though 🙂 Avoid fat-free/skim milk.
HOW TO MAKE BISQUICK BREAKFAST CASSEROLE WITH SAUSAGE: STEP-BY-STEP
Here are some quick visual instructions. Remember that full instructions with exact ingredients will be in the recipe card below!
Step 1: Cook breakfast sausage in a large skillet. Add onions, red bell pepper and/or green pepper. Add to casserole dish.
Step 2: In a large bowl, whisk together eggs, Bisquick, cheese, milk, mustard, maple syrup, salt and pepper.
Step 3: Pour the egg mixture into the casserole dish over the sausage, onions, and peppers.
Step 4: Heat oven to 375°F and bake the sausage egg casserole for 35-40 minutes until golden brown around the edges and eggs are cooked in the middle.
RECIPE TIPS & TRICKS
- Freshly grated cheese: Cheese that is freshly grated (vs. pre packaged) ALWAYS tastes better and melts better than pre-packaged cheese. If you have 5 extra minutes, grate up your own from the block!
- Cover with foil: If you see the edges getting a bit too brown before the center of the casserole is cooked through, loosely cover the baking dish with aluminum foil.
- Add cheese at the end: Reserve a bit of cheese and add it during the last few minutes of cooking for a nice, cheesy topping!
Casey’s Top Tip: No need for fancy tools to get your sausage broken up up nice and fine! Use a potato masher during the last minute of cooking to break up the meat–it works like a charm!
STORAGE & REHEATING
- Storage: Leftovers can be stored in the fridge right in the baking dish, covered tightly with foil or plastic wrap for up to 3 days. You can also transfer individual servings to an airtight container or Ziploc bag and store them in the fridge for 3-4 days.
- Reheating: Reheat individual portions in the microwave for 30-60 seconds.
- Freezing: This breakfast casserole freezes up great after it’s been cooked. For best results, use a disposable, freezer-safe baking dish like these. Cover tightly with several layers of foil and freeze for up to 2 months.
Additions and Substitutions
ADDITIONS:
- Meat Lovers: Add another pound of sausage or chopped, cooked bacon!
- Veggie: Skip the meat all together and add more peppers and onions! Mushrooms are a great addition, too.
- Hash Browns: I personally feel this casserole is carb-y enough already with the Bisquick, but I won’t lie, it’s also delicious with potatoes!! Add 2 cups of FROZEN shredded hash browns to the egg mixture.
- Spice it Up! Hot sauce, chopped jalapeno or diced green chilies are great ways to add some heat to this Bisquick breakfast casserole!
SUBSTITUTIONS:
- Pork Sausage: Although pork sausage is the most common breakfast sausage, Jennie-O also makes a really yummy turkey breakfast sausage if you want to lighten it up. Try maple breakfast sausage for some added sweetness.
- Milk: Low fat, whole milk, half and half and even heavy cream work just fine in this recipe. Avoid using skim milk as it’s a bit too watery.

Bisquick Breakfast Casserole with Sausage
Ingredients
- 1 lb. breakfast sausage bulk, without casings. Both pork sausage or turkey sausage work great.
- 1 cup onion, chopped
- 1 bell pepper, chopped any color, or use a combo!
- 6 large eggs
- 1 cup Bisquick All-Purpose Baking Mix
- 2 cups cheese, grated sharp cheddar cheese, Monterey Jack, mozzarella cheese…choose you favorites!
- 2 cups milk whole milk works best, but low-fat milk or half and half are also OK
- 3 tsp mustard
- 2 tbsp maple syrup
- 1/2 tsp kosher salt See Note 1
- black pepper to taste
Instructions
- Prep: Preheat oven to 375°F and spray a 9×11 baking dish (or similar) with cooking spray.
- CookSsausage and Peppers: In a large skillet, cook sausage, breaking it up with a wooden spoon as it cooks. Pro Tip: Use a potato masher during the last minute of cooking to get the meat broken up nice and fine. When the sausage is cooked, drain the grease. Then, add onion and bell pepper to the skillet with the cooked sausage. Cook 1 minute more. Transfer the veggie and sausage mixture to your baking dish.
- Whisk: In a large mixing bowl, whisk eggs, Bisquick, milk, mustard, maple syrup, salt, pepper, and 1 1/2 cups of the cheese (reserve the rest of the cheese for the top, at the end of cooking). Whisk until all ingredients are well-combined.
- Bake: Pour the Bisquick mixture into the baking dish over the sausage and veggies. Bake, uncovered for 35-40 minutes until the edges are golden brown and the center is nearly set. The center might be A LITTLE jiggly, but it will continue to set when it comes out of the oven. A few minutes before you are ready to take it out of the oven, sprinkle on the remaining cheese.
- Finish: Take the casserole out of the oven and let it rest for 10-15 minutes before cutting it into squares. Optional: sprinkle with green onions or parsley for a little freshness!
I love this!! And will be making of course I have to cut it down lots since its just me. But I think enough for 3 meals would be enough. This is so easy and looks so good.
This was the perfect, easy casserole to make for a busy weeknight! Thank you so much!
This looks so yummy! Can I use almond milk instead of dairy milk?
I have no tested it with almond milk but i imagine it would be just fine. Might change the flavor SLIGHTLY but go for it! Report back and let us know! XO~ Casey
Quick question: I’m making this for breakfast tomorrow morning – is the mustard dry or prepared?
I used prepared in the recipe but you can sub dry if you have it 🙂
Oh, this looks SOOO good. I would love to make this with my Grandson for Christmas morning.
A great Christmas recipe, thank you.
Delicious! I love the use of Bisquick instead of potatoes to the mix. Great easy flavors that everyone loves for our weekend brunch!
