French Onion Ground Beef Rice

This French onion ground beef and rice casserole is the kind of cozy meal you throw together on a weeknight but still feel good serving to friends or family. It is comforting creamy savory and so simple to prepare with just a few classic ingredients you probably already have in your kitchen. Over the years this casserole has rescued many busy evenings for me whether at potlucks or just when everyone shows up for dinner hungry.

The first time I made this it was just to use up some leftover rice but now my family routinely begs for it. There is always an empty dish at the end.

Gather Your Ingredients

• Ground beef: choose lean for less grease but enough fat for flavor
• Cooked white rice: opt for day old or cold rice for the best texture
• Condensed French onion soup: this shortcut brings classic savory flavor
• Sour cream: gives creaminess and a mild tang that balances the dish
• Shredded mozzarella cheese: melts smoothly and adds cheesy goodness
• Butter: for sautéing and adding richness
• Onion powder and garlic powder: enhances beefy flavor and brings out the onion notes
• Chopped parsley: adds fresh color and herby flavor use flat leaf for best results

How to Make It

Brown the Beef and Build Flavor:

In a large skillet melt the butter over medium heat until foamy then add ground beef and cook slowly breaking it up with your spoon. Keep stirring for about eight to ten minutes until browned fragrant and no longer pink. Be sure to drain excess fat to keep the casserole from becoming greasy.

Season the Aromatics:

Once the beef is browned stir in onion powder and garlic powder and a pinch of salt and black pepper. Keep stirring over low heat for one minute allowing spices to bloom and fragrance to release.

Mix Everything Together:

Transfer the cooked beef mixture into a large mixing bowl. Add the cooked rice French onion soup sour cream and most of the cheese set some aside for topping. Mix gently but thoroughly making sure rice beef and sauce are evenly combined.

Prepare the Baking Dish:

Preheat your oven to three hundred fifty degrees Fahrenheit one hundred seventy five degrees Celsius. Grease a nine by thirteen inch baking dish well with butter or nonstick spray to prevent sticking.

Assemble and Top:

Spoon the beef and rice mixture into the prepared pan and spread evenly with a spatula. Sprinkle reserved mozzarella cheese over the top for a golden bubbly finish.

Bake to Perfection:

Slide the casserole into the oven uncovered. Bake for thirty to forty five minutes until edges are bubbling and cheese on top is golden brown. If the top seems pale broil for one or two minutes at the end but keep a close eye to avoid burning.

Rest and Serve:

Let the casserole rest for at least five to ten minutes for best slicing. Garnish with fresh chopped parsley and serve warm.

My favorite touch is the parsley on top because it brightens the whole dish. There is a special memory of having a kitchen full of laughter while grating fresh cheese and someone always sneaking a taste.

Flavor Boosters

Swap the ground beef for ground turkey or chicken if you want a lighter version. For extra vegetables stir in some sautéed bell peppers mushrooms or even thawed frozen spinach before baking. Cheddar or Swiss cheese also work if you like sharper flavors.

Serving Suggestions

This casserole pairs perfectly with a side salad dressed in vinaigrette or simple roasted green beans. It also works well as a main for Sunday dinner or as a hearty addition to any potluck. Sometimes I toast up crusty bread to serve alongside for maximum comfort.

Creative Twists

In the fall stir in roasted mushrooms or a handful of cooked butternut squash. In spring fresh herbs like thyme or chives brighten the casserole. When it is cold outside I sometimes top the baked dish with extra crispy fried onions.

This dish has become a tradition for a reason. It brings people together especially on cold nights.
