The History Behind the Flavor

French Onion Beef & Rice Casserole

French Onion Soup has a long and delicious history, with its roots tracing back to ancient Roman times. The modern version we know and love, with its rich broth, caramelized onions, and melted cheese, became popular in 18th-century Paris.

This French Onion Beef Rice Casserole takes inspiration from these classic flavors. I kept the key ingredients like beef broth and caramelized onions (hello, French onion soup!), which work together to create a truly comforting dish.

Ingredients for French Onion Beef Rice Casserole

  • 1 pound ground beef (lean)
  • ½ to 1 tsp garlic salt (or to taste)
  • 2 (10.5 ounce) cans beef consume
  • 2 (10.5 ounce) cans french onion soup
  • ¾ cup water
  • 2 cups long grain white rice (uncooked (not minute rice))
  • ¾ cup butter (1 ½ stick, cut into slices)

Ingredient Notes & Recommendations

I prefer using beef consume because it has a richer, more concentrated flavor than regular beef broth. However, if you can’t find beef consume, beef broth will work just fine.

Also, to elevate the French onion flavor, I sometimes add a splash of sherry or balsamic vinegar to the beef mixture. Swanson’s beef consume is my go-to brand for this recipe, and I find it at most grocery stores.

Essential Equipment

To make this casserole, you’ll need a few essential pieces of equipment. A 9×13 inch baking dish is a must, as it provides the perfect size for the casserole to bake evenly. You’ll also need a large skillet to brown the ground beef.

As an alternative to the skillet, a Dutch oven, like one from Le Creuset, works wonders because you can brown the beef and then bake the whole casserole in the same pot.

How to Make French Onion Beef Rice Casserole

Here are the simple steps to making my French Onion Beef Rice Casserole:

Step 1: Getting Started

Preheat oven to 425°F. Spray a 9X13 inch baking dish with cooking spray.

Step 2: Brown the Ground Beef

In a large skillet, add ground beef and garlic salt to season. Cook and crumble ground beef until browned and cooked through.

Step 3: Combine Ingredients

In a prepared baking dish add rice and ground beef. Pour in soup, broth, and water and stir until combined.

Step 4: Add Butter

Cut butter into slices and place on top of the mixture.

Step 5: Bake Covered

Cover with foil and bake for 30 minutes.

Step 6: Bake Uncovered

Remove foil and bake for 30 minutes more. * see the notes section for a cheesy and crispy topping version.

Step 7: Fluff and Serve

Once done fluff with a fork and serve.

Variations and Substitutions

VariationDescription
Mushroom MedleyAdd sliced cremini, shiitake, or oyster mushrooms for an earthy flavor. Sauté them with the onions for best results.
Cheesy DelightUse Gruyere, Swiss, or provolone cheese on top during the last 15 minutes of baking for a bubbly, melted cheese topping.
Spicy KickAdd a pinch of red pepper flakes or a dash of hot sauce to the beef mixture. Consider using pepper jack cheese for extra heat.
Healthier OptionSubstitute ground turkey for ground beef. Use low sodium beef broth and soups to reduce sodium intake. Use brown rice instead of white rice.

Kid-Friendly Adaptations

To make this casserole more appealing to kids, I sometimes cut the beef into smaller pieces so it’s easier for them to eat. Using a milder cheese, like Monterey Jack, is another great way to make it more kid-friendly. A fun twist is to add a layer of mashed potatoes on top before baking; kids love mashed potatoes!

Serving Suggestions

This casserole is a meal on its own, but I love serving it with a simple green salad to add some freshness to the meal. Roasted vegetables, such as broccoli or carrots, are also a great complement to the rich flavors of the casserole. It is really nice to have something healthy with the casserole.

For another healthy option, you can try the Italian Penicillin Soup Recipe to pair with this casserole.

Make it Spicy

If you’re like me and enjoy a bit of heat, there are several ways to spice up this casserole. A pinch of red pepper flakes added to the beef mixture can provide a subtle kick. Diced jalapeños are also a great addition for those who like a bit more heat. And for a bold flavor, a dash of your favorite hot sauce will definitely do the trick!

Consider looking in the snacks & drinks section for your favorite hot sauce.

Storing and Reheating French Onion Beef Rice Casserole

To store leftovers, allow the casserole to cool completely before transferring it to an airtight container. Store it in the refrigerator for up to 3-4 days. For longer storage, you can freeze the casserole for up to 2-3 months. To prevent freezer burn, wrap the casserole tightly in plastic wrap before placing it in a freezer-safe container.

When reheating, thaw the casserole in the refrigerator overnight if frozen. To reheat, bake in a preheated oven at 350°F (175°C) until heated through, about 20-30 minutes. I like to add a splash of beef broth to keep the rice moist. You can also reheat individual portions in the microwave, but the texture may be slightly different.

Troubleshooting

ProblemSolution
Rice is UndercookedAdd ¼ cup of water, cover with foil, and bake for another 15-20 minutes.
Casserole is Too DryAdd a little more beef broth or water during the last 15 minutes of baking.
Top is Not BrownedBroil for the last 2-3 minutes, watching carefully to prevent burning.
Rice is StickingEnsure the baking dish is well-greased. Next time, try adding a thin layer of cheese to the bottom of the dish before adding the rice.

Frequently Asked Questions

Can I use a different type of onion?

While French onion soup traditionally uses yellow onions, you can experiment with other types of onions in this casserole. Sweet onions, like Vidalia, can add a sweeter flavor, while red onions can provide a sharper bite. Just remember that different onions have different cooking times, so adjust accordingly.

How do I prevent the rice from sticking to the dish?

To prevent the rice from sticking, make sure to grease your baking dish thoroughly with cooking spray. As mentioned in the troubleshooting table, you can also try adding a thin layer of shredded cheese to the bottom of the dish before adding the rice. The cheese creates a barrier and helps to prevent sticking.

Can I use pre-caramelized onions to save time?

Yes, you can definitely use pre-caramelized onions to save time! Many grocery stores sell pre-caramelized onions in the refrigerated section. Just be sure to adjust the amount of French onion soup you use, as the pre-caramelized onions may already have a lot of flavor.

Can you use brown rice or instant rice to make this rice casserole?

While I personally prefer long grain white rice for this recipe, you can substitute brown rice if you prefer. Keep in mind that brown rice will require a longer cooking time and more liquid, so you’ll need to adjust the recipe accordingly.
I don’t recommend using instant rice, as it can become mushy during baking. If you opt for brown rice, keep in mind that a serving of ground beef with rice prepared this way <a href="https://www.snapcalorie.com/nutrition/ground<em>beef</em>with<em>ricecontains about 411.8 calories.

Can rice casserole be made in a rice cooker or Instant Pot?

I haven’t personally tried making this casserole in a rice cooker or Instant Pot, but it’s definitely possible! You’ll need to adjust the cooking times and liquid amounts accordingly.
