Recipe FAQs

Can I make this casserole vegetarian?

Yes, you can easily make this casserole vegetarian by substituting ground beef or turkey with a plant-based ground meat alternative. You can also increase the variety of vegetables, such as adding mushrooms or zucchini, and use vegetable broth instead of beef or chicken broth.

Can this casserole be made ahead of time?

Yes, this casserole is a great make-ahead meal. You can prepare the casserole up to the point before adding the cheese, cool it, and then store it covered in the refrigerator. When you’re ready to eat, add the cheese on top and bake until the cheese is melted and the casserole is heated through.

How can I make this casserole spicier?

For a spicier casserole, you can add diced jalapeños to the vegetable mix or add in some red pepper flakes.

How long will this casserole keep?

Leftovers keep well in the fridge for up to 3 days. For a fun twist, repurpose the casserole into actual stuffed bell peppers for a delicious next-day meal.

What’s the best way to reheat leftovers?

Leftovers can be reheated in the microwave or the oven. Place a portion of the casserole in a microwave-safe dish, cover with a microwave-safe lid or paper towel, and heat on high until warm throughout. To reheat in the oven, cover casserole with aluminum foil and bake at 350°F until heated through, typically about 20 minutes.

Serving Suggestions

This stuffed pepper casserole is a hearty meaty meal on it’s own! Here are a few favorite sides though that I love to serve with it.
