How to Make French Onion Ground Beef and Rice Casserole Recipe

Step 1: Caramelize the onions

Start by heating olive oil in a large skillet over medium heat. Add the thinly sliced onions and cook slowly for 10 to 12 minutes until they turn a rich, golden brown color. This step is crucial because these caramelized onions bring that iconic French onion sweetness and deep flavor that create the backbone of this casserole.

Step 2: Brown the ground beef

Next, add the ground beef to the skillet with the onions. Break the meat apart as it cooks for about 5 to 7 minutes until fully browned. Be sure to drain any excess grease—this keeps the casserole from becoming too oily while locking in the savory essence of the beef.

Step 3: Prepare the rice

While the beef cooks, rinse your long-grain white rice under cold water to remove excess starch. You can either cook it partially according to package instructions or add it uncooked directly with the beef broth to the casserole, where it will slowly absorb the savory flavors during baking.

Step 4: Combine the casserole mixture

In a large mixing bowl, combine the caramelized onion and beef mixture with the rice and beef broth. Add garlic powder, onion powder, dried thyme, salt, and pepper to taste. Stir everything gently until the ingredients are evenly mixed. This blend sets the stage for a rich, flavorful casserole that’s bursting with comfort at every spoonful.

Step 5: Bake the casserole

Transfer the combined mixture to a greased 9×13-inch baking dish. Cover tightly with aluminum foil and bake in a preheated oven at 350°F (175°C) for 30 minutes. This allows the rice to cook thoroughly while absorbing the robust beef and onion flavors.

Step 6: Add the cheese and finish baking

Remove the foil and sprinkle a generous layer of shredded Swiss cheese over the top. Return the casserole to the oven and bake for another 10 to 15 minutes until the cheese is melted, bubbly, and slightly golden. This melted Swiss cheese layer adds creamy richness that’s utterly irresistible.

Step 7: Top with crispy fried onions

Just before serving, sprinkle the crispy fried onions over the cheese and bake uncovered for an additional 5 minutes. This final step delivers a wonderful crunchy texture and enhances the classic French onion soup experience packed into every bite of this hearty casserole.

Make Ahead and Storage

Storing Leftovers

Once cooled to room temperature, transfer any leftovers to an airtight container. Store in the refrigerator for up to 3 to 4 days. This casserole reheats beautifully and the flavors actually deepen the next day.

Freezing

For longer storage, freeze the casserole in portion-sized containers or the entire dish tightly covered. It can be kept frozen for up to 2 months. Thaw in the refrigerator overnight before reheating to maintain the best texture and flavor.

Reheating

Reheat leftovers covered in the microwave or in the oven at 350°F until warmed through. To revive the crispy onion topping, add fresh fried onions or briefly broil the casserole uncovered for a crisp finish.

FAQs

Can I use other types of cheese instead of Swiss?

Absolutely! Gruyère, mozzarella, or even a sharp white cheddar can work nicely, depending on your taste preferences. Just keep in mind Swiss cheese offers that nutty, mild flavor that complements the onions perfectly.

Is it necessary to caramelize the onions first?

Yes, caramelizing the onions slowly brings out their natural sweetness and depth, which is essential to this casserole’s signature French onion flavor. Skipping this step will result in a less rich and flavorful dish.

Can I make this casserole gluten-free?

Yes! Just ensure you use gluten-free beef broth and gluten-free crispy fried onions for topping. The rest of the ingredients are naturally gluten-free.

What type of rice works best in this recipe?

Long-grain white rice is perfect because it cooks evenly and remains fluffy. You can experiment with brown rice, but you’ll need to adjust cooking time and liquid amounts accordingly.

Can I add vegetables to the casserole?

Definitely! Diced mushrooms, bell peppers, or peas make wonderful additions and add extra color, flavor, and nutrition. Just fold them in along with the rice before baking.
