Whenever I’m craving something homey but don’t want to fuss much, I go for this French Onion Ground Beef and Rice Casserole. All that cozy French onion soup flavor mixes up with creamy beef and melty cheese in one easy pan. Whether it’s a chilly night or you need a crowd-pleaser for a potluck, every bite just feels like a hug from home.
Whenever I whip this up, my family always comes back for more. One time I shared it with a friend after her surgery—she called as soon as she could saying she needed to know how I made it.
Mouthwatering Ingredients
- Shredded mozzarella cheese: gives that perfect gooey top If you shred your own from a block it melts the best
- Cream of mushroom soup: brings a lovely creamy feel and rich savory notes If you can, choose the less salty kind
- Shredded cheddar cheese: sharp or medium both add some nice bite for contrast
- Ground beef: packs in rich flavor and you get your protein If you don’t want too much fat, go for a lean blend
- French onion soup: brings the signature deep onion taste A quality canned soup works great
- Garlic powder: makes everything taste a bit more interesting Smell it and make sure it’s potent
- Dried thyme: it's optional but brings gentle earthy vibes Whole leaves work best if you can find them
- Cooked white rice: Jasmine or long grain both soak up the flavors and get perfectly tender
- Parsley or green onions for garnish: just add this fresh on top right before serving for color
- Onion: totally optional for a fresh, mild-sweet pop Any yellow or white onion fits
- Black pepper: wakes up all the flavors If you have cracked pepper, even better
Simple Step-by-Step
- Rest and Dish Up:
- Let things settle once it’s out of the oven—give it 5 or 10 minutes so it’ll hold together nicely When you serve, sprinkle over some chopped parsley or green onions for a little color and zip
- Bake:
- Slide it into the oven covered with foil at 350 F Let it steam for 20 minutes After that, pull the foil and bake about 10 to 15 minutes more— you want a bubbling center and a toasty top
- Add Cheese:
- Throw on all your mozzarella first, then pile on the cheddar Cover the whole top to get that dreamy cheese pull
- Get Your Pan Ready:
- Spread the rice and beef combo into your greased 9-by-13 pan Smooth it out so it’s all even for baking
- Mix That Rice:
- Stir in the cooked rice right into your pan with everything else Make sure it all gets coated with sauce so it’s an even bite every time
- Let the Flavors Mesh:
- Now add in your soups (French onion and cream of mushroom), garlic powder, black pepper, and thyme Let this bubble on the stove for a couple of minutes so the flavors mingle
- Sauté Onions (if using):
- If you’re tossing in onion, cook it in the pan for 3 or 4 minutes Give it a stir now and then You just want them soft and barely golden
- Brown the Beef:
- In a big skillet, break up and cook the beef on medium high till it’s browned and crumbly—usually 5 to 7 minutes Tip out any grease so it doesn’t get heavy

Recipe FAQs
- → Can I swap in another meat?
Go for it! Turkey or chicken ground up will work in place of beef. The taste won’t be as rich, so you might want to add another pinch of your favorite seasoning.
- → Which rice is best here?
Cooked white rice turns out perfect, but brown or wild rice can be tossed in too as long as it’s already cooked.
- → Is it fine to use just one cheese kind?
Definitely! Use just cheddar or mozzarella if that’s all you’ve got, or swap in Swiss or Gruyère for extra yum.
- → Can I put it together early?
For sure! You can assemble everything, cover it, and stash it in the fridge. Bake it the next day and just give it 10–15 extra minutes to warm through.
- → What’s the best way to store extras?
Let it cool, then wrap it up and keep in the fridge up to three days. Warm it back up in the oven or in your microwave.
- → Is the onion a must?
You don’t have to use onion, but it does add that classic flavor. Skip it or toss in more if you love onions as much as I do!
