Ingredients
- 1 pound ground beef (80/20 or leaner)
- 1 ½ cups long-grain white rice (uncooked)
- 1 large onion, thinly sliced
- 2 cups beef broth
- 1 cup French onion soup (canned or homemade)
- 1 cup shredded mozzarella cheese
- ½ cup shredded cheddar cheese
- 2 tablespoons unsalted butter
- 1 teaspoon Worcestershire sauce
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- ½ teaspoon black pepper
- ½ teaspoon salt (adjust as needed)
- 1 tablespoon fresh parsley (for garnish)
Step-by-Step Instructions
Step 1: Prepare the Onions
In a large skillet, melt the butter over medium heat. Add the thinly sliced onions, stirring occasionally, and let them cook slowly. Caramelizing onions properly takes about 15-20 minutes, but patience is key! You want them to turn golden brown and develop that rich, sweet flavor. If they start to burn, reduce the heat slightly and stir more frequently.
Step 2: Brown the Ground Beef
Once the onions are caramelized, push them to the side of the skillet and add the ground beef. Cook over medium-high heat, breaking it apart with a spoon, until it’s fully browned and no longer pink. Drain any excess grease, then stir the onions and beef together to combine their flavors.
Step 3: Add the Rice and Seasoning
Sprinkle the garlic powder, onion powder, black pepper, and salt over the beef and onions. Stir well to coat everything evenly. Next, add the uncooked long-grain white rice and stir again, allowing the rice to absorb some of the flavorful fat from the beef and onions.
Step 4: Add Liquids and Simmer
Pour in the beef broth, French onion soup, and Worcestershire sauce, stirring everything together. Bring the mixture to a gentle simmer, then reduce the heat to low. Cover the skillet with a lid and let it cook for about 20 minutes, or until the rice has fully absorbed the liquid and is tender. Avoid stirring too often to prevent the rice from becoming mushy.
Step 5: Transfer to a Baking Dish
Once the rice is cooked and the mixture is thickened, transfer everything into a lightly greased 9×13-inch baking dish. Spread it out evenly with a spatula.
Step 6: Add Cheese and Bake
Sprinkle the mozzarella and cheddar cheese evenly over the top of the casserole. Preheat your oven to 375°F (190°C) and bake uncovered for 15-20 minutes, or until the cheese is melted and bubbly. If you prefer a crispy golden top, you can switch the oven to broil for the last 2-3 minutes, but keep a close eye to prevent burning.
Step 7: Garnish and Serve
Remove the casserole from the oven and let it sit for 5 minutes to allow the flavors to settle. Sprinkle freshly chopped parsley over the top for a pop of color and freshness. Serve warm and enjoy!
Ingredient Background
The magic of this French Onion Ground Beef & Rice Casserole comes from a handful of humble ingredients that, when combined, create an explosion of flavor. Let’s take a deeper look at some of the key components.
Onions – The Star of the Show
Onions have been a staple in cooking for centuries, prized for their ability to add depth and sweetness to dishes. When caramelized, they transform into a rich, golden delicacy, intensifying the overall taste of the casserole. The natural sugars in onions break down during slow cooking, resulting in a sweet and savory flavor profile that defines French onion soup—and this casserole.
Ground Beef – The Protein Powerhouse
Ground beef is one of the most versatile proteins in the kitchen. It provides a meaty, hearty base for this dish, absorbing the flavors of the onions and seasoning. For a healthier version, you can opt for lean ground beef (90/10) or ground turkey, but a little fat (like in 80/20 beef) helps create a richer taste.
Rice – The Comforting Foundation
Rice serves as the backbone of this casserole, soaking up all the flavors from the broth, onions, and beef. Long-grain white rice works best because it stays fluffy and separate rather than becoming mushy. Brown rice can be substituted for a nuttier taste and added fiber, though it requires a longer cooking time.
Technique Tips for French Onion Ground Beef & Rice Casserole
Perfecting Caramelized Onions
The key to caramelized onions is patience. Cooking them too fast on high heat will burn them before they develop their characteristic deep golden hue. Instead, keep the heat medium-low and stir occasionally. If they start to stick, a splash of broth or water will help deglaze the pan.
Preventing Mushy Rice
To achieve fluffy, separate rice, avoid stirring too often while it’s cooking in the broth. Stirring activates the starches, which can result in a sticky or gummy texture. Instead, let the rice absorb the liquid naturally and fluff it gently with a fork before transferring to the baking dish.
Getting the Perfect Cheese Crust
For a truly irresistible cheesy topping, mix mozzarella and cheddar. Mozzarella melts smoothly, creating that gooey pull, while cheddar adds sharpness and depth. If you like a crispy top, turn on the broiler for the last two minutes of baking. Just be sure to watch closely, as cheese can burn quickly.
Alternative Presentation Ideas
Mini Casserole Servings
Instead of a large baking dish, try making individual portions in ramekins or small oven-safe bowls. This is a great way to serve this dish at dinner parties or family gatherings while keeping presentation elegant and portion sizes controlled.
Stuffed Bell Peppers
For a creative twist, scoop out the seeds from large bell peppers and fill them with the cooked beef, onion, and rice mixture. Top with cheese and bake until the peppers are tender. This adds color to your dish and provides extra vegetable goodness.
Crispy Topping Variation
If you enjoy a bit of crunch, sprinkle buttered breadcrumbs or crushed crispy onions on top before baking. This adds a delightful crispy texture that contrasts beautifully with the creamy, cheesy casserole.
Freezing and Storage
Refrigeration Tips
Once cooled, store leftovers in an airtight container and refrigerate for up to 4 days. When reheating, use the oven at 350°F (175°C) for about 15 minutes to maintain the texture, or microwave in smaller portions for quick meals.
Freezing for Later
This casserole is perfect for meal prep! To freeze, allow the dish to cool completely before wrapping it tightly in plastic wrap and aluminum foil. It can be frozen for up to 3 months. When ready to eat, thaw overnight in the fridge and reheat in the oven at 375°F (190°C) until warmed through.
Best Way to Reheat
For leftovers that taste fresh, reheat in a covered dish in the oven to prevent drying out. Adding a small splash of beef broth before reheating can help retain moisture.
Healthier Twist Ideas
Swap White Rice for Brown Rice or Quinoa
Brown rice adds fiber and nutrients while giving the casserole a nuttier flavor. Quinoa is another fantastic substitute, offering extra protein and a slightly firmer texture.
Use Ground Turkey or Chicken Instead of Beef
For a leaner alternative, substitute ground turkey or chicken for beef. This cuts down on saturated fat while keeping the dish just as flavorful, especially when seasoned well.
Reduce the Cheese or Use a Low-Fat Version
While cheese is delicious, using a light sprinkle of reduced-fat cheese or opting for part-skim mozzarella can lower the calorie count without compromising flavor.
Serving Suggestions for Events
Family Dinners
This dish is ideal for weeknight meals because it’s simple, filling, and made in one pan. Serve with a side of roasted vegetables or a fresh green salad for a balanced dinner.
Holiday Potlucks
Casseroles are always a hit at potlucks, and this one is no exception. To make it travel-friendly, bake it in a disposable aluminum pan and cover it tightly with foil to keep it warm.
Game Night or Movie Night
This casserole is great for casual get-togethers. Serve it in small bowls with toasted bread on the side, allowing guests to scoop up the cheesy goodness.
