Ingredients for this French Onion Beef Rice Casserole Recipe

• 1 pound ground beef
• 1 cup long-grain white rice, uncooked
• 2 ½ cups beef broth
• 1 can (10.5 oz) condensed French onion soup
• 1 tablespoon Worcestershire sauce
• ½ teaspoon garlic powder
• 1 teaspoon onion powder
• 1 cup shredded mozzarella cheese (optional topping)
• Fresh parsley for garnish (optional)
• Salt and black pepper to taste

Step 1: Brown the Ground Beef

In a large skillet over medium heat, cook the ground beef until it’s fully browned and no longer pink. Use a wooden spoon to break the meat into crumbles as it cooks. Once done, drain excess grease to avoid a greasy casserole.

---

Step 2: Mix the Casserole Base

Preheat your oven to 350°F (175°C). In a large mixing bowl, combine the browned ground beef, uncooked white rice, beef broth, condensed French onion soup, Worcestershire sauce, garlic powder, onion powder, salt, and pepper. Stir until everything is well incorporated.

Step 3: Transfer to a Baking Dish

Pour the mixture into a greased 9×13-inch baking dish. Spread it out evenly using a spatula. If you’re using cheese, save it for later in the baking process to avoid burning.

---

Step 4: Bake Covered

Cover the dish tightly with aluminum foil and bake in the preheated oven for 50 to 55 minutes. This allows the rice to fully cook by absorbing the flavorful liquid while locking in moisture.

---

Step 5: Add Cheese and Finish Baking

If using shredded mozzarella cheese, remove the foil and sprinkle the cheese evenly over the top. Return the casserole to the oven, uncovered, and bake for an additional 5–10 minutes, or until the cheese is melted and lightly golden.

Step 6: Garnish and Serve

Once baked, let the casserole rest for 5 minutes. This helps the rice set and makes serving easier. Sprinkle with freshly chopped parsley for a burst of color and freshness before serving.

Frequently Asked Questions

1. Can I use brown rice instead of white rice?

Yes, but keep in mind brown rice takes longer to cook. Increase baking time by about 15–20 minutes and check for doneness.

2. Is it okay to use ground turkey instead of beef?

Absolutely. Ground turkey works well as a leaner alternative and still absorbs all the flavors beautifully.

3. Can I make this casserole in advance?

Yes! You can assemble it ahead, cover tightly, and refrigerate for up to 24 hours before baking.

4. What can I use instead of French onion soup?

You can use homemade French onion soup or mix a beef broth base with sautéed onions and seasoning if you prefer less processed options.

5. How do I make it spicier?

Add red pepper flakes, cayenne pepper, or diced jalapeños to the beef mixture to turn up the heat.

6. Can I add vegetables?

Definitely. Mushrooms, peas, or bell peppers make great additions without altering the base flavors too much.

7. What cheese substitutes work well?

Try provolone, Gruyère, or Swiss cheese if you’re not a fan of mozzarella.

8. How do I avoid mushy rice?

Be sure to use long-grain rice and measure liquids carefully. Overcooking can also cause mushiness—stick to the recommended time.
