Instructions
Preheat oven to 375°F and spray a 9x11 baking dish (or similar) with cooking spray.
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 sausage is cooked, drain the grease. Then, add onion and bell pepper to the skillet with the cooked sausage. Cook 1 minute more. Transfer mixture to the baking dish.
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.
Pour 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.
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!
Notes
Note 1: This may not seem like a lot of salt, but the Bisquick mix already has a good amount of salt in it already...so we don't want to overdo it! Nutrition information is only an estimate. Info is based on the Very Well Fit Nutrition Calculator.
