How to Make French Onion Ground Beef and Rice Casserole

Step 1: Caramelize the Onions

Start by slicing your yellow onions thinly. Heat butter or olive oil in a large skillet over medium-low heat and cook the onions slowly, stirring occasionally, until they turn golden brown and sweetly fragrant. This process usually takes about 30-40 minutes but is key for that signature French onion flavor.

Step 2: Cook the Ground Beef

In a separate pan, brown the ground beef over medium heat. Break it up with a spoon and cook until no longer pink. Season with salt, pepper, and a pinch of thyme for a fragrant touch. Drain any excess fat if desired.

Step 3: Combine Rice and Broth

Prepare your rice according to package instructions, but use beef broth instead of water to add savory depth. You want slightly undercooked rice since it will finish cooking in the casserole.

Step 4: Mix Everything Together

In a large bowl, combine the caramelized onions, cooked ground beef, and rice. Add minced garlic, a bit of butter, and a pinch of salt and pepper to round out the flavors. Stir everything until evenly distributed.

Step 5: Assemble and Bake

Transfer the beef, rice, and onion mixture to a greased casserole dish. Top generously with shredded Swiss or Gruyere cheese. Bake in a preheated 350°F (175°C) oven for 20-25 minutes or until the cheese is melted and bubbly with slight golden browning.

Pro Tips for Making French Onion Ground Beef and Rice Casserole

• Patience Matters for Onions: Don’t rush caramelizing—they develop the dish’s signature sweetness and depth.
• Use Warm Broth for Rice: Cooking rice in warm broth aids faster absorption and better flavor integration.
• Cheese Choice is Key: Swiss and Gruyere melt well and offer authentic tangy notes essential to the recipe.
• Don’t Overcook Rice Initially: Slightly underdone rice finishes perfectly baked and prevents mushiness.
• Let It Rest Before Serving: Letting the casserole sit for 5-10 minutes after baking helps it set and slice cleanly.

How to Serve French Onion Ground Beef and Rice Casserole

Garnishes

Fresh herbs like chopped thyme or parsley add a burst of color and fresh aroma. A light sprinkle of cracked black pepper or a few thinly sliced green onions can also enhance presentation and flavor contrast.

Side Dishes

Complement the casserole with a crisp green salad dressed in a tangy vinaigrette or steamed green vegetables such as broccoli or green beans to balance the richness of the dish.

Creative Ways to Present

Serve individual portions in small ramekins for a quaint, personalized dinner experience or top the casserole with crispy onions or crushed toasted nuts for added texture and visual interest.

Make Ahead and Storage

Storing Leftovers

Allow the casserole to cool completely before transferring leftovers to an airtight container. Refrigerate for up to 3-4 days to preserve freshness and flavor.

Freezing

French Onion Ground Beef and Rice Casserole freezes beautifully. Portion it into freezer-safe containers and freeze for up to 3 months. Thaw in the fridge overnight before reheating.

Reheating

Reheat individual servings in the microwave or warm the entire casserole in a 350°F oven for 15-20 minutes, covering with foil to prevent over-browning. Add a sprinkle of cheese on top before reheating for a melty finish.

FAQs

Can I use instant rice instead of regular rice?

Instant rice cooks much faster and absorbs liquids differently, so it isn’t recommended for this casserole as it may become mushy during baking.

Is this recipe suitable for keto or low-carb diets?

Swap traditional rice with cauliflower rice to make this casserole low-carb and keto-friendly without losing texture or flavor.

Can I make this recipe dairy-free?

Yes, using dairy-free butter substitutes for caramelizing onions and dairy-free cheese alternatives will make the dish suitable for those avoiding dairy.

How do I get the onions to caramelize without burning?

Cook them over low to medium heat, stirring frequently, and be patient. Adding a splash of water during cooking can help prevent burning while allowing caramelization.

Can I prepare this casserole ahead and bake it later?

Absolutely! Assemble the casserole, cover tightly, and refrigerate for up to 24 hours before baking. Just add a few extra minutes to the baking time if baking straight from the fridge.
