FAQs

What is Bisquick and what does it do in this recipe?

Bisquick is a pre-mixed baking mix made of flour, leavening, salt, and fat. It simplifies baking and helps create a fluffy, slightly cake-like texture in this casserole.

Can I make this casserole the night before?

Yes, assemble the casserole and refrigerate it overnight. Bake it in the morning as directed.

Do I need to cook the sausage before adding it to the casserole?

Yes, the sausage should be fully cooked and drained before mixing it into the casserole to avoid excess grease and ensure food safety.

Can I use bacon instead of sausage?

Absolutely. Cooked and crumbled bacon works well as a substitute for sausage and adds a smoky flavor.

How do I know when the casserole is fully cooked?

Insert a knife or toothpick in the center. If it comes out clean and the center is firm, it’s ready.

Can I make this casserole dairy-free?

Yes, use a plant-based milk and dairy-free cheese alternative to make it suitable for dairy-free diets.

Is this recipe gluten-free?

Not as written, but you can use a gluten-free baking mix in place of Bisquick to make it gluten-free.

Can I use egg substitutes?

Yes, liquid egg substitutes or a mix of whole eggs and egg whites can be used with minor texture changes.

How can I make this recipe lower in fat?

Use lean turkey sausage, low-fat cheese, and skim milk to reduce the overall fat content.

Can I double the recipe for a larger group?

Yes, simply double all ingredients and bake in two 9×13-inch pans, or use a larger baking dish and adjust baking time accordingly.
