This French Onion Soup Rice transforms a beloved soup flavor into a comforting side dish that pairs beautifully with almost any protein. The rice absorbs all those rich, caramelized onion flavors while baking to tender perfection.

I first made this recipe during a particularly hectic week when I needed something effortless yet impressive. My family was so enamored with the rich, savory flavor that it's now in our regular rotation for both everyday meals and special occasions.

Ingredients

  • Long grain rice ensures the grains remain separate and fluffy after baking, creating the perfect texture
  • Campbells French Onion Soup provides the signature caramelized onion flavor and rich color without hours of onion-cooking
  • Beef broth enhances the savory depth and helps create the perfect liquid ratio for properly cooked rice
  • Butter creates a luxurious richness and helps the rice develop a delicious golden crust on top

Step-by-Step Instructions

Prep Your Baking Dish
Pour the uncooked long grain rice into your 8×8 baking dish, spreading it in an even layer across the bottom. Make sure you're using a dish with enough depth to accommodate the liquid and allow the rice to expand during cooking.
Combine The Liquids
Open both cans and pour the French onion soup and beef broth directly over the rice. Gently stir to ensure all rice grains are submerged in the liquid mixture. This even distribution ensures the rice will cook uniformly.
Add The Butter
Slice the butter into thin pats and arrange them evenly across the top of the rice mixture. As the dish bakes, the butter will melt and create pockets of richness throughout the rice while also helping to form a delicious crust on top.
Initial Baking Phase
Cover the baking dish tightly with aluminum foil. This traps steam during the first cooking stage, which is essential for proper rice hydration. Place in your preheated 425°F oven and bake for 25 minutes.
Final Baking Phase
Carefully remove the foil (watch for hot steam) and return the dish to the oven. This uncovered phase allows excess moisture to evaporate and creates that beautiful texture contrast between the tender rice below and the slightly crisp top layer. Bake for an additional 20-25 minutes until the rice is tender and has absorbed all the liquid.

The magic of this dish truly lies in how the French onion soup transforms ordinary rice into something extraordinary. When I first served this to my grandmother, she insisted I must have spent hours caramelizing onions. The convenience of using prepared soup brings that same depth of flavor with minimal effort.

Storage and Reheating

This rice dish stores exceptionally well in the refrigerator for up to four days in an airtight container. When reheating, I recommend adding a small splash of beef broth or water to restore moisture, then covering with a damp paper towel when microwaving. For best results, reheat in a 325°F oven covered with foil until warmed through. The flavor actually deepens overnight, making it perfect for meal prep or planned leftovers.

Flavor Variations

While the classic version is perfect on its own, this recipe welcomes creative additions. Try stirring in sautéed mushrooms before baking for an earthy dimension. Adding a half cup of grated Gruyère or Swiss cheese during the final 10 minutes of baking creates a French onion soup inspired experience. For an elegant twist, stir in a tablespoon of brandy or sherry with the broth ingredients. Each variation maintains the ease of preparation while offering new flavor profiles.

Perfect Pairings

This rich, savory rice complements numerous main dishes. Serve alongside a simple roasted chicken or grilled steak where its oniony depth enhances the meat without competing. For a lighter option, pair with a bright green salad dressed with vinaigrette the acidity balances the rice's richness. I particularly love serving this alongside pork tenderloin with a mustard sauce where the flavors create a perfect harmony reminiscent of French bistro cuisine.

Frequently Asked Questions

→ Can I use brown rice instead of white rice?

Yes, you can substitute brown rice, but you'll need to increase the baking time by approximately 15-20 minutes and may need to add an extra 1/4 cup of liquid. Brown rice requires longer cooking to become tender.

→ Can I make this dish ahead of time?

Absolutely! Prepare as directed, allow to cool, then refrigerate in an airtight container for up to 3 days. Reheat covered in a 350°F oven for 15-20 minutes or microwave individual portions with a splash of broth.

→ What can I serve with French onion rice?

This versatile side pairs wonderfully with grilled or roasted meats like chicken, steak, or pork chops. It also complements roasted vegetables or a simple green salad for a complete meal.

→ Can I add vegetables to this dish?

Yes! Consider adding sautéed mushrooms, peas, or diced carrots before baking. Pre-cook firmer vegetables slightly to ensure they're tender when the rice is done.

→ Is there a way to make this dish vegetarian?

Substitute the beef broth with vegetable broth and check that your French onion soup is vegetarian (or use a vegetarian version). The flavor profile will be slightly different but still delicious.

→ Can I add cheese to this rice dish?

Absolutely! For a true French onion experience, sprinkle 1/2 cup of grated Gruyère or Swiss cheese over the rice during the last 5 minutes of baking for a wonderful cheesy topping.
