Notes
I’ve experimented with different variations of this recipe, and one of my favorites is adding a handful of sliced mushrooms to the skillet along with the onions. It adds an earthy flavor that pairs perfectly with the French onion soup taste.

Variations
If you’re looking to switch things up, you can try using ground turkey instead of ground beef for a leaner option. Additionally, you can swap the mozzarella cheese for Swiss or Gruyere to give the casserole a slightly different flavor profile.
Equipment
While not essential, a cast-iron skillet works wonders for browning the ground beef and onions. If you don’t have one, a regular skillet will do the job just fine.
Storage Information
This casserole can be stored in an airtight container in the refrigerator for up to 3 days. Although, in my house, it never lasts more than a day as everyone always goes back for seconds!
Serving Suggestions
I love serving this French Onion Ground Beef and Rice Casserole with a side of steamed vegetables or a fresh green salad. The crispness of the veggies provides a nice contrast to the creamy and cheesy casserole.
Pro Tips
One lesson I’ve learned from experience is not to rush the browning process of the ground beef. Taking the time to properly brown it adds depth and richness to the overall flavor of the casserole. Trust me; it’s worth the extra few minutes!
FAQ
Q: Can I use brown rice instead of long-grain rice?
A: Absolutely! Brown rice will work just fine in this recipe, but keep in mind that it may require a slightly longer cooking time.
Q: Can I freeze this casserole?
A: Yes, you can freeze this casserole for up to 3 months. Simply let it cool completely, wrap it tightly in plastic wrap and foil, and pop it in the freezer. When you’re ready to enjoy it, thaw it in the refrigerator overnight and reheat in the oven until heated through.
Q: Can I use vegetable broth instead of beef broth?
A: While beef broth adds a rich flavor to the casserole, you can certainly use vegetable broth as a substitute if you prefer a vegetarian version of the dish.
So there you have it – my go-to French Onion Ground Beef and Rice Casserole recipe. It’s a comforting and flavorful dish that will satisfy your cravings and leave you feeling warm and cozy. Give it a try, and I’m sure it’ll become a favorite in your home too!
