How to Make French Onion Ground Beef and Rice Casserole

Step 1: Caramelize the Onions

Start by heating butter and olive oil in a large skillet over medium heat. Add thinly sliced yellow onions and cook slowly, stirring often, until they turn golden brown and sweetly fragrant—this can take about 20 minutes but is the heart of the flavor.

Step 2: Brown the Ground Beef

Push the onions to the side and add ground beef to the skillet. Cook until well browned and cooked through, making sure to break it up into crumbles for even texture.

Step 3: Add Aromatics and Liquids

Mix in minced garlic and thyme, then pour in Worcestershire sauce and beef broth. Let everything simmer for a few minutes so the flavors meld and the broth slightly reduces.

Step 4: Combine with Rice

Stir in uncooked rice, ensuring each grain is coated with the savory mixture. Season with salt and pepper, and allow the liquid to absorb slightly before transferring to a baking dish.

Step 5: Bake with Cheese

Top the mixture with shredded Swiss or Gruyere cheese, then bake in a preheated oven at 350°F (175°C) until the rice is tender and the cheese is bubbly and golden—usually around 25 to 30 minutes.

Pro Tips for Making French Onion Ground Beef and Rice Casserole

• Take your time with onions: Slow caramelization builds the deep flavor essential to this dish’s success.
• Don’t rinse your rice: Keeping the starch helps achieve a creamier texture in the casserole.
• Use a tight-fitting lid or foil: Cover the casserole while baking to prevent the rice from drying out.
• Let it rest before serving: Allow 5-10 minutes after baking for flavors to settle and the casserole to firm up.
• Choose quality broth: Using a flavorful beef broth significantly enhances the overall taste.

How to Serve French Onion Ground Beef and Rice Casserole

Garnishes

Fresh herbs such as chopped parsley or thyme add a bright contrast and a pop of color, while a sprinkle of freshly cracked black pepper gives a little extra kick.

Side Dishes

This casserole pairs beautifully with a crisp green salad dressed with a tangy vinaigrette, or roasted vegetables like asparagus or broccoli to add freshness and balance the richness of the main dish.

Creative Ways to Present

Serve it straight from the casserole dish for a cozy family-style meal, or plate individual portions topped with a dollop of sour cream or a drizzle of caramelized onion jam for an elegant twist.

Make Ahead and Storage

Storing Leftovers

Allow the casserole to cool completely, then store in an airtight container in the refrigerator for up to 3-4 days. The flavors deepen as it rests, making leftovers a delightful second meal.

Freezing

You can freeze the baked casserole in portions or whole. Wrap tightly in foil or use freezer-safe containers, and it will keep well for up to 3 months. Thaw overnight in the refrigerator before reheating.

Reheating

Reheat leftovers in the oven at 350°F (175°C) until warmed through to keep the crispy cheese topping intact. Alternatively, microwave individual servings, stirring halfway through for even heating.

Can I freeze the casserole before baking?
