Recipe Info

Ingredients You’ll Need

• 1 lb (450 g) ground beef
• 1 medium onion, chopped
• 2 cloves garlic, minced
• 1 cup uncooked white rice
• 2 cups beef broth
• 1 (10.5 oz) can French onion soup
• 1 tsp dried thyme
• ½ tsp black pepper
• ½ tsp salt (adjust to taste)
• 1 cup shredded Swiss or mozzarella cheese
• 2 tbsp butter
• 2 tbsp all-purpose flour

Step-By-Step Instructions

1. Preheat the Oven:
   Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish lightly with butter or cooking spray.
2. Cook the Beef and Onions:
   In a large skillet, melt butter over medium heat. Add chopped onion and cook for 5–6 minutes until soft and translucent.
   Add garlic and cook 30 seconds until fragrant. Stir in ground beef and cook until browned, breaking up large chunks. Drain excess fat if needed.
3. Make the Onion Sauce:
   Sprinkle flour over the beef mixture and stir for 1–2 minutes to remove the raw flour taste. Slowly stir in French onion soup and beef broth, bringing to a gentle simmer. Cook for 3–5 minutes until slightly thickened.
4. Combine with Rice:
   Stir in uncooked rice, thyme, salt, and pepper. Mix well to evenly distribute rice and seasonings.
5. Assemble the Casserole:
   Transfer the mixture into the prepared baking dish. Cover with foil and bake for 30 minutes. Remove foil and sprinkle shredded cheese over the top. Bake uncovered for an additional 10 minutes, until cheese is melted and bubbly.
6. Serve Warm:
   Let the casserole rest for 5 minutes before serving. Scoop generous portions onto plates and enjoy the cozy, comforting flavors.

Helpful Notes & Tips

• Rice Tips: Use long-grain white rice for fluffy results; brown rice will need slightly more liquid and extra cooking time.
• Cheese Swap: Swiss, mozzarella, or Gruyère all work beautifully for a melty, flavorful topping.
• Storage: Keep leftovers in an airtight container in the fridge for up to 3 days. Reheat gently in the oven or microwave.
• Flavor Boost: Add a splash of Worcestershire sauce or a pinch of smoked paprika for extra depth.

Recipe Variations

• Ground Turkey: Substitute lean ground turkey for a lighter, healthier option.
• Vegetable Boost: Add mushrooms, bell peppers, or spinach for extra nutrition and color.
• Spicy Kick: Stir in ¼ tsp crushed red pepper flakes or cayenne for a subtle heat.

Serving Suggestions

Pair your French Onion Ground Beef and Rice Casserole with:

• A crisp side salad with tangy vinaigrette
• Garlic bread or warm baguette slices
• Steamed green beans or roasted broccoli for a balanced meal

This cozy casserole is perfect for weeknight dinners or a comforting family lunch.
