Ingredients You’ll Need

You only need a short lineup of ingredients to craft this casserole, but each one plays a key role. The result is a dish that’s hearty, satisfying, and brimming with down-home flavor — each bite tells its own story.

• Ground beef (1 pound, lean): Go for a leaner ground beef to limit excess grease and let the savory flavors shine through.
• Garlic salt (½ to 1 tsp, or to taste): The secret punch of flavor; sprinkle judiciously to keep every bite seasoned.
• Beef consomme (2 cans, 10.5 ounce each): This concentrated, robust broth boosts the meaty depth of the casserole.
• French onion soup (2 cans, 10.5 ounce each): French onion soup brings those caramelized, rich onion flavors without hours spent at the stove.
• Water (¾ cup): A splash helps the rice cook up perfectly in the oven.
• Long grain white rice (2 cups, uncooked): Be sure to use classic long grain, not quick or minute rice, for that fluffy, slightly chewy texture.
• Butter (¾ cup, about 1½ sticks, sliced): Dotted butter on top ensures a golden crust and silky finish for the rice beneath.

How to Make French Onion Ground Beef and Rice Casserole

Step 1: Prep Your Baking Dish

Preheat your oven to 425°F and grab a 9X13 inch baking dish. Give it a quick mist with cooking spray so nothing sticks and you get those beautiful, easy-to-serve slices later. This step sets the foundation for a fuss-free dinner.

Step 2: Brown the Beef

In a large skillet over medium-high heat, crumble the ground beef and season with garlic salt. Cook until the beef is browned and fully cooked, breaking it apart as it sizzles. This not only creates tender morsels but also builds a flavor base that you’ll taste in every forkful.

Step 3: Combine Rice and Beef in the Dish

Spoon the uncooked long grain rice into your prepared baking dish, then scatter the cooked ground beef on top. This layering trick lets the juices soak through the rice, making it extra flavorful and ensuring every bite is seasoned.

Step 4: Add the Soups and Water

Pour both cans of beef consomme and both cans of French onion soup into the dish. Add the ¾ cup water as well. Gently stir everything together right there in the dish — no need for extra bowls! Each grain of rice will slowly absorb all those savory liquids as the casserole bakes.

Step 5: Dot with Butter

Slice up the butter and arrange it evenly over the top of the casserole. As it bakes, the butter will melt down into the rice and meat, creating a golden, slightly crispy topping and lending a luscious richness to the entire dish.

Step 6: Cover and Bake

Cover the baking dish tightly with foil and slide it into the oven. Let it bake for 30 minutes, allowing the rice to steam gently and the flavors to mingle. After that, peel off the foil for the remaining 30 minutes so the top can get those lovely caramelized edges reminiscent of classic French onion soup.

Step 7: Fluff and Serve

Once the timer dings, your kitchen will be filled with the inviting aroma of the French Onion Ground Beef and Rice Casserole. Let it sit for a minute, then lightly fluff the rice with a fork before serving. Every spoonful is layered with savory beef, soft rice, and those subtle onion flavors that make this casserole so memorable.

How to Serve French Onion Ground Beef and Rice Casserole

Garnishes

A sprinkle of chopped fresh parsley or thyme can brighten up your casserole just before serving. For a cheesy flair, try tossing some shredded Gruyere or Swiss over the hot casserole and let it melt in — just like your favorite bowl of French onion soup.

Side Dishes

Pair your French Onion Ground Beef and Rice Casserole with a crisp green salad tossed in vinaigrette, buttery green beans, or a loaf of crusty French bread to mop up every last bit of goodness. The richness of the casserole is perfectly balanced by sides that add a little freshness and crunch.

Creative Ways to Present

For a fun twist, scoop portions into individual ramekins for a dinner party, or stuff leftovers into hollowed-out bell peppers and bake until tender. You could also serve this casserole family-style at the center of the table, letting everyone dig in for a true crowd-pleaser.

Make Ahead and Storage

Storing Leftovers

If you find yourself with leftovers, simply transfer them to an airtight container once cooled. The flavors continue to deepen overnight, making for an even tastier lunch the next day. Store in the refrigerator for up to 4 days.

Freezing

French Onion Ground Beef and Rice Casserole freezes beautifully. Spoon cooled portions into freezer-safe containers, label, and freeze for up to 3 months. Just remember, the texture of the rice may become a little softer after thawing, but the flavor remains fantastic.

Reheating

Reheat portions in the microwave, covered, with a splash of broth or water to keep things moist. For larger amounts or a crisper top, cover with foil and heat in a 350°F oven until hot. Either way, give it a good fluff before serving to bring everything back to life.

FAQs

Can I use brown rice instead of white rice?

You can swap in long grain brown rice, but keep in mind it will require a longer baking time and perhaps a bit more liquid. Check after the full hour and add extra warm broth if needed until the rice is perfectly tender.

What’s the best way to add cheese for a true French onion flavor?

Sprinkle shredded Gruyere or Swiss cheese over the casserole during the last 10 minutes of baking, uncovered. It will melt beautifully and give you that irresistible, traditional French onion soup topping.

Can I prep French Onion Ground Beef and Rice Casserole ahead of time?

Absolutely! Assemble the casserole up to the point of baking, cover well, and refrigerate for up to 24 hours. When ready to bake, let it sit at room temperature for about 15 minutes before putting it in the oven.

Is it possible to use ground turkey or chicken instead of beef?

Yes, ground turkey or ground chicken can be used as a lighter alternative to beef. You might want to add an extra pinch of seasoning since turkey and chicken are milder in flavor, but the end result will still be delicious.

How can I make this casserole gluten free?

Check that your canned soups are labeled gluten-free, and use gluten-free broth if needed. Some canned French onion soups contain wheat, so always read the label to ensure your French Onion Ground Beef and Rice Casserole is safe for everyone at your table.
