Short Description

This French Onion Ground Beef and Rice Casserole features layers of savory ground beef, caramelized onions, and tender rice topped with melted cheese. A perfect cozy meal for any occasion.

Key Ingredients

For the Casserole:

• 1 tablespoon olive oil (or butter)
• 2 large onions (thinly sliced)
• 1 lb ground beef
• 2 cloves garlic (minced)
• 1 cup uncooked long-grain white rice
• 2 cups beef broth
• 1 teaspoon Worcestershire sauce
• 1 teaspoon dried thyme
• Salt and pepper (to taste)

For the Topping:

• 1 1/2 cups shredded mozzarella cheese (or Gruyère for a French onion twist)
• 1/2 cup grated Parmesan cheese

Optional Garnish:

• Fresh parsley (chopped, for brightness)

Tools Needed

• Large skillet or oven-safe pan
• Wooden spoon or spatula
• Oven
• Baking dish (if using instead of skillet)

Cooking Instructions

Step 1: Caramelize the Onions
Start by heating the olive oil in a large skillet over medium heat. Add the thinly sliced onions and cook, stirring occasionally, for about 15-20 minutes.

Keep an eye on them to avoid burning. Once they’re caramelized, remove the onions from the pan and set them aside.

Step 2: Cook the Ground Beef
In the same skillet, add the ground beef and cook it over medium heat. Break it into small pieces with a wooden spoon. Cook until browned, about 5-7 minutes. Drain any excess fat.

Stir in the minced garlic and cook for an additional minute, allowing the garlic to become fragrant and infuse the beef with its savory aroma.

Step 3: Build the Casserole
Return the caramelized onions to the skillet with the beef. Add in the uncooked rice, beef broth, Worcestershire sauce, dried thyme, and salt and pepper.

Stir everything together, making sure the rice is evenly distributed in the mix. Bring the mixture to a simmer, then reduce the heat to low and cover.

Let it cook for 15-20 minutes, or until the rice is tender and the liquid is mostly absorbed.

Step 4: Add the Cheese
Preheat your oven to 375°F (190°C). Once the rice is cooked and the casserole has come together, sprinkle the shredded mozzarella and Parmesan cheese over the top.

Step 5: Bake the Casserole
Transfer the skillet (or the casserole mixture to a baking dish) into the preheated oven. Bake for 15-20 minutes or until the cheese is melted, bubbly, and slightly browned on top.

Step 6: Serve and Enjoy
Let the casserole cool slightly before serving. Garnish with freshly chopped parsley for a burst of color and freshness. Dig in and enjoy the cheesy, savory goodness!

Why You’ll Love This Recipe

Rich Flavor: The caramelized onions and beef provide deep, savory flavors, while the cheese topping adds richness and texture.

Versatile: It’s the perfect dish for a family dinner, meal prep, or even a cozy gathering with friends.

Comforting: This casserole hits all the right notes with its satisfying layers and creamy cheese topping—perfect for any comfort food craving.

Mistakes to Avoid & Solutions

Onions not caramelizing properly: Make sure you’re cooking the onions low and slow. If the heat is too high, they might burn before they caramelize properly. Stir them regularly and give them time to develop that rich, sweet flavor.

Rice not cooking fully: Ensure you let the casserole simmer covered for the full 15-20 minutes. If the rice seems too firm, add a splash of extra beef broth and let it cook longer.

Cheese not melting evenly: If you notice the cheese isn’t melting as smoothly as you’d like, pop the casserole under the broiler for 1-2 minutes at the end of baking to achieve that golden, bubbly crust.

Serving and Pairing Suggestions

Serve as a main: This casserole is hearty enough to stand alone as a meal. Pair it with a light side salad or some roasted vegetables for a balanced dinner.

Pairing Drinks: A glass of red wine, like Cabernet Sauvignon or a lighter Merlot, complements the richness of the beef and cheese.

Family-style: Serve it directly from the skillet for a rustic, family-style dinner.

Storage and Reheating Tips

Storage: Leftovers can be stored in an airtight container in the fridge for up to 3 days.

Reheating: To reheat, simply cover the casserole with foil and bake at 350°F (175°C) for 15-20 minutes or until heated through. You can also microwave individual servings for 1-2 minutes, but the oven method keeps the crust intact.

FAQs

1. Can I use ground turkey instead of beef? Yes, you can swap ground beef for ground turkey for a leaner option. The flavor will be slightly milder, but still delicious!

2. Can I make this casserole ahead of time? Absolutely! You can prepare everything up to the point of baking, cover it, and refrigerate it for up to 24 hours. Just bake it when you’re ready to serve.

3. Can I use brown rice instead of white rice? Yes, but keep in mind that brown rice takes longer to cook, so you’ll need to increase the simmer time and potentially add more broth.

4. Can I use a different cheese? Sure! Gruyère or Swiss cheese would give it a lovely French onion twist. You can also mix in cheddar for a different flavor profile.

5. Can I freeze this casserole? Yes! Let it cool completely before covering tightly and freezing for up to 3 months. Thaw it in the fridge overnight and reheat as directed.

Tips & Tricks

For extra flavor: Add a dash of balsamic vinegar or a splash of red wine when caramelizing the onions. It brings out an additional layer of depth.

Cheese swap: If you prefer a sharp flavor, Gruyère or a combination of Gouda and cheddar will create a unique flavor profile.

Recipe Variations

Vegetarian version: Replace the ground beef with lentils or mushrooms for a hearty vegetarian option.

Spicy twist: Add a pinch of crushed red pepper flakes when cooking the ground beef to give the casserole a little heat.

One-pan option: If you prefer to keep it all in one pan, use a deep oven-safe skillet, and skip transferrin
