French Onion Soup Rice (Printable)

Caramelized onions and Gruyère meld with tender rice and savory broth in a cheesy, bake-topped casserole.

# What You'll 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)
11 - 1/2 teaspoon salt, or to taste
12 - 1/4 teaspoon black pepper

→ Topping

13 - 1 cup French bread croutons or cubes, toasted

# Directions:

01 - Preheat oven to 375°F. 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 caramelized and golden brown, approximately 25 minutes.
03 - Stir in the minced garlic and thyme leaves. Cook for 1 minute until fragrant.
04 - Pour in the white wine if using, scraping up any browned bits from the bottom of the pan. Let simmer for 2–3 minutes to reduce slightly.
05 - Add the rinsed rice to the onion mixture, stirring to coat each grain. Cook for 2 minutes, allowing the rice to lightly toast and absorb the flavors.
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 10–12 minutes until the cheese is melted and bubbling.
09 - Let the casserole stand for 5 minutes before serving to allow the flavors to settle and the cheese to set slightly.

# Expert Tips:

01 -
  • All the deeply savory, cheese pulled magic of French onion soup without babysitting a pot of liquid for hours.
  • It uses pantry staples and turns them into something that tastes like you tried much harder than you actually did.
02 -
  • If you cranked the heat on those onions and they turned dark brown in ten minutes, they are burnt, not caramelized. Low and slow is the only path to true sweetness.
  • Skipping the foil cover was my biggest early mistake because uncovered rice dries out before it ever gets tender, so seal that dish tightly.
03 -
  • A pinch of sugar sprinkled over the onions in the first five minutes helps them caramelize more evenly and deeply without any detectable sweetness in the final dish.
  • Let the casserole rest that full five minutes because serving it too hot means the rice releases steam onto your plate and the cheese slides right off instead of settling into each bite.
