French Onion Ground Beef and Rice Casserole Ingredients
•
- For the Casserole
- Ground Beef – Provides protein and savory flavor; use lean beef or turkey for a lighter version.
- Onions – Adds sweetness when caramelized for a rich base; sweet or yellow onions work best for that deep flavor.
- Rice (long-grain) – Serves as the carb component that absorbs flavors; do not substitute with instant rice, as it may become mushy.
- Cream of Mushroom Soup – Acts as a binder and adds creaminess; can be replaced with a gluten-free version for dietary needs.
- Beef Broth – Enhances the overall richness and moisture; vegetable or chicken broth can be used if preferred.
Step‑by‑Step Instructions for French Onion Ground Beef and Rice Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This step is crucial as it ensures your French Onion Ground Beef and Rice Casserole cooks evenly. While the oven warms up, grab a large sauté pan and get ready to brown the ground beef.
Step 2: Brown the Ground Beef
In your skillet over medium heat, add the ground beef and cook for about 5-7 minutes, stirring occasionally. You’ll know it’s done when there’s no pink remaining and it’s nicely browned. Drain any excess fat, leaving approximately one tablespoon in the pan to add flavor to your onions.
Step 3: Caramelize the Onions
Reduce the heat to medium-low and add butter with sliced onions to the pan. Sauté for 10-15 minutes until the onions become golden and caramelized, stirring frequently. The sweetness of the onions will complement the savory beef beautifully and fill your kitchen with a delightful aroma.
Step 4: Combine All Ingredients
Stir in the uncooked long-grain rice, cream of mushroom soup, beef broth, and seasonings to the pan. Mix thoroughly until everything is well combined, and the mixture looks soupy. This flavorful blend is the heart of your casserole, bringing comfort to every bite.
Step 5: Transfer to Baking Dish
Pour the mixture into a greased 9×13-inch baking dish, spreading it evenly. This casserole will need to be covered tightly with foil to retain moisture during baking. Place it in the preheated oven and bake for 25 minutes, allowing the rice to absorb all the delicious flavors.
Step 6: Add Cheese and Finish Baking
After 25 minutes, remove the foil and sprinkle shredded cheddar cheese generously over the top of your casserole. Place it back in the oven uncovered for an additional 10 minutes, watching closely until the cheese is melted and bubbly. For an extra touch, you can broil it for the last minute to achieve a beautiful golden crust.
Step 7: Let it Rest Before Serving
Once your French Onion Ground Beef and Rice Casserole is finished baking, let it sit for about 5 minutes before serving. This resting time allows the flavors to deepen and the casserole to set just right, ensuring each portion is hearty and delicious.

Expert Tips for French Onion Ground Beef and Rice Casserole
-
Meat Choice Matters: Use a lean ground beef or turkey for a lower-fat option. This helps keep the casserole light while still flavorful.
-
Onion Caramelization: Take your time when caramelizing the onions to achieve that deep sweetness—a rushed job could lead to uneven flavors.
-
Rice Tips: Always use long-grain rice rather than instant. Instant rice can become mushy and won’t absorb the delicious broth properly.

Cheese Options: Experiment with different cheeses! While shredded cheddar is a classic choice, swapping in Gruyère or Monterey Jack can elevate the flavors of your French Onion Ground Beef and Rice Casserole.
-
Cover Tightly: Be sure to cover the baking dish tightly with foil during the initial bake. This preserves steam, ensuring the rice cooks perfectly fluffy.
-
Add Veggies: Don’t hesitate to fortify your casserole with sautéed veggies like bell peppers or zucchini for added nutrition and color.
