🛒 Ingredients You’ll Need

Here’s what goes into this cozy casserole:

1 pound ground beef

1 cup long-grain white rice (uncooked)

1 can (10.5 oz) French onion soup

1 can (14.5 oz) diced tomatoes, undrained

1 cup beef broth

1 medium onion, sliced

Salt and pepper, to taste

Optional toppings: shredded cheese, crispy fried onions, fresh parsley

👨‍🍳 How to Make French Onion Ground Beef and Rice Casserole

This dish comes together in just a few simple steps:

1. Brown the Beef

In a large skillet or deep sauté pan, cook the ground beef over medium-high heat until browned and fully cooked. Drain excess grease. Season lightly with salt and pepper.

2. Add the Aromatics

Add the sliced onion to the skillet and cook for about 5 minutes until softened and slightly caramelized. The onion adds a rich sweetness that enhances the overall flavor of the casserole.

3. Stir in the Base

Add the uncooked rice, French onion soup, diced tomatoes (with juice), and beef broth. Stir everything together well, making sure the rice is evenly distributed.

4. Simmer and Bake

Transfer the mixture to a lightly greased 9×13 baking dish. Cover with foil and bake at 350°F (175°C) for 45–50 minutes, or until the rice is tender and the liquid is absorbed.

5. Add Optional Toppings

Remove the foil and, if desired, sprinkle shredded cheese or crispy fried onions on top. Return to the oven uncovered for an additional 5–10 minutes to brown the top and melt the cheese.

6. Serve It Hot

Let it sit for 5 minutes before serving. Sprinkle with fresh chopped parsley for a little color if you like.

🧀 Tips + Tricks for the Best Casserole

Use long-grain white rice – other types (like instant or brown rice) may require different cooking times and liquid amounts.

Make it cheesy – stir in a cup of shredded cheddar or mozzarella before baking for extra creaminess.

Double the recipe – this dish freezes well, so it’s great for batch cooking.

Caramelize your onions – taking time to really brown them deepens the French onion flavor.

Let it rest – like all good casseroles, this one gets even better after sitting for a few minutes post-bake.

🍽️ What to Serve With This Dish

This casserole is hearty enough to stand alone, but here are some great pairings to round out your meal:

Steamed green beans or broccoli – a little green always helps balance the richness

Simple garden salad – add a crisp, fresh element to your plate

Buttered dinner rolls or garlic toast – for sopping up all that savory goodness

Apple coleslaw – sweet and tangy slaw adds a refreshing crunch

🥶 Storing & Reheating

This casserole stores and reheats beautifully—making it a fantastic make-ahead meal.

To refrigerate: Cover leftovers tightly and store in the fridge for up to 4 days.
