French Onion Soup Rice (Printable Version)
Savory casserole of caramelized onions, broth, Gruyère and tender rice, baked until bubbly and golden.
# What You Need:
→ Vegetables
01 - 2 large yellow onions, thinly sliced
02 - 2 cloves garlic, minced
→ Grains
03 - 1 cup long-grain white rice, rinsed
→ Dairy
04 - 2 tablespoons unsalted butter
05 - 1 cup shredded Gruyère cheese
06 - 1/4 cup grated Parmesan cheese
→ Liquids
07 - 2 1/4 cups low-sodium beef or vegetable broth
08 - 1/4 cup dry white wine (optional)
→ Pantry Staples
09 - 1 tablespoon olive oil
10 - 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
11 - 1/2 teaspoon kosher salt, or to taste
12 - 1/4 teaspoon freshly ground black pepper
→ Topping
13 - 1 cup French bread croutons or cubes, toasted
# Directions:
01 - Preheat oven to 375°F (190°C). Grease a 2-quart casserole dish and set aside.
02 - In a large skillet, heat olive oil and butter over medium-low heat. Add the sliced onions with a pinch of salt and cook, stirring frequently, until deeply golden brown and caramelized, about 25 minutes.
03 - Stir in the minced garlic and thyme leaves. Cook for 1 minute until fragrant.
04 - Pour in the dry white wine if using, scraping up any browned bits from the bottom of the pan. Let simmer for 2 to 3 minutes to reduce slightly.
05 - Add the rinsed rice to the skillet, stirring to coat each grain with the onion mixture. Cook for 2 minutes to lightly toast the rice.
06 - Transfer the onion-rice mixture to the prepared casserole dish. Pour in the broth, season with salt and pepper, and stir gently to combine.
07 - Cover the dish tightly with aluminum foil and bake for 30 minutes until the rice has absorbed most of the liquid.
08 - Remove the foil and fluff the rice with a fork. Sprinkle the shredded Gruyère and grated Parmesan evenly over the top, then scatter the toasted croutons. Bake uncovered for an additional 10 to 12 minutes until the cheese is melted and bubbling.
09 - Let the casserole stand for 5 minutes before serving to allow the flavors to settle.
# Expert Tips:
01 -
- It captures every bit of that deeply caramelized, cheesy magic of French onion soup but requires zero delicate bowl handling or broiler acrobatics.
- The rice soaks up the rich broth and wine until every single grain tastes like it was cooked with intention and care.
02 -
- Do not crank the heat to speed up the onions because burnt edges will make the whole casserole taste bitter instead of sweet and deep.
- Covering the dish tightly with foil is non-negotiable since that trapped steam is what cooks the rice evenly.
03 -
- Slice your onions as evenly as possible so they caramelize at the same rate and you do not end up with some burnt and some still raw.
- Let the casserole rest the full 5 minutes because serving it too early means the rice is slightly wet and the cheese has not set into that perfect gooey layer.
