❔ FAQs
There's no definitive answer for this, but most cowboy casserole recipes include ingredients that would've been easy for cowboys to cook and eat while they were out on the range!
No, some cowboy casserole recipes have a cornbread topping, a layer of potatoes, or biscuits. There are many ways to prepare this dish and many times it comes down to personal preference!
If you didn't drain the corn before adding it, there may be excess moisture in your casserole. The same is true of the beef; make sure to dispose of any grease or moisture before you mix it into the casserole.

📝 Substitutions and Variations
- Ground turkey and ground chicken can be used instead of ground beef for a lighter version of this casserole.
- For some extra color, flavor, and heartiness, mix in green beans, peas, or diced bell pepper.
- Monterey Jack and Pepper Jack are both great options to use instead of or alongside the cheddar.
- Use cream of celery or cream of chicken soup instead of the cream of mushroom if you like.
