Ingredients

2 large yellow onions, thinly sliced (about 5 cups)
3 tablespoons unsalted butter (plus 1 tablespoon olive oil, optional, to prevent scorching)
1 cup long-grain white rice (jasmine or basmati work; rinse until water runs clear)
2 cups broth (beef for classic French onion flavor; chicken or vegetable also work)
2 cloves garlic, minced
1–2 teaspoons fresh thyme leaves (or 1/2 teaspoon dried)
1 tablespoon Worcestershire sauce or 2 tablespoons dry sherry (optional but clutch)
1 bay leaf
1 teaspoon kosher salt, plus more to taste
1/2 teaspoon black pepper
1/2 cup shredded Gruyère or Swiss cheese (optional, for melty top)
2 tablespoons grated Parmesan (optional, for savory finish)
Fresh chives or parsley, chopped, for garnish

How to Make It – Instructions

Preheat and prep: Heat your oven to 350°F (175°C). Rinse the rice in cold water until clear; drain well.
Caramelize the onions: In a large oven-safe skillet or Dutch oven, melt butter (and olive oil, if using) over medium heat.
Add sliced onions and 1/2 teaspoon salt. Cook 20–25 minutes, stirring every few minutes, until deep golden and jammy. If they brown too fast, lower heat and splash in a tablespoon of water to deglaze.
Add aromatics: Stir in garlic and thyme; cook 1 minute until fragrant.
Add Worcestershire or sherry and scrape up any browned bits.
Toast the rice: Add rinsed rice to the onions. Stir 1–2 minutes to coat the grains in buttery goodness. This boosts texture and flavor.
Add liquid: Pour in broth, add bay leaf, remaining salt, and pepper.
Stir to combine, bring to a gentle simmer.
Bake: Cover tightly with a lid or foil and bake 18–22 minutes, until rice is tender and liquid is absorbed.
Cheesy finish (optional but amazing): Remove lid, sprinkle Gruyère and Parmesan on top, and bake uncovered 5 minutes until melted and lightly browned. Broil 1–2 minutes if you want extra bubbly edges—watch closely.
Rest and fluff: Let rest 5–10 minutes off heat. Remove bay leaf, fluff with a fork, and garnish with chives or parsley.
Serve: Pair with roast chicken, seared steak, garlicky mushrooms, or a crisp salad if you’re pretending to be balanced.

Preservation Guide

Storage: Cool completely, then refrigerate in an airtight container for up to 4 days.
Freezing: Portion into freezer bags or containers, press flat, and freeze up to 2 months.
Thaw overnight in the fridge.
Reheating: Add a splash of broth or water. Microwave covered in 60–90 second bursts, fluffing between, or reheat on the stovetop over low heat with a lid.
Make-ahead tip: Caramelize onions a day ahead and refrigerate. Assembly the next day takes minutes, and your future self will high-five you.

Benefits of This Recipe

Time-smart flavor: You get soup-level depth in under an hour thanks to concentrated onions and a quick bake.
Versatile side or main: Add rotisserie chicken, mushrooms, or white beans and it becomes a one-pan dinner.
Comfort without heavy lifting: Rich, cozy, and crowd-pleasing with minimal chopping and cleanup.
Budget and pantry friendly: Onions + rice + broth = elite value.
Your wallet says merci.
Scalable: Double it in a larger pan for gatherings. It disappears—consider that your only problem.

Common Mistakes to Avoid

Rushing the onions: Pale onions = bland rice. Go for deep golden-brown.
Adjust heat and take your time.
Skipping the rinse: Unrinsed rice can get gummy. Rinse until the water runs mostly clear.
Wrong pan size: A too-small pan creates uneven cooking. Use a wide, oven-safe skillet or a Dutch oven.
Lid leaks: If the lid isn’t tight, steam escapes and rice cooks unevenly.
Use foil under the lid if needed.
Too much stirring after baking: Stir gently to fluff. Aggressive mixing mashes grains—no thanks.

Different Ways to Make This

Mushroom French Onion Rice: Sauté 8 oz sliced cremini with the onions for umami overload. Finish with a splash of soy sauce.
Chicken Dinner Version: Nestle seasoned chicken thighs on top before baking; increase bake time 10–15 minutes until chicken hits 165°F.
One pan, done.
Vegetarian Classic: Use vegetable broth and double the Gruyère or sub smoked provolone. Add white beans for protein.
Brown Rice Swap: Use 1 cup brown rice to 2.25 cups broth; bake 45–50 minutes, checking at 40. Still stellar, just slower.
Pressure Cooker Hack (FYI): After caramelizing on Sauté, add rice and liquid, then cook on High Pressure for 4 minutes (white rice), natural release 10 minutes.
Stir in cheese after.
Gluten-Free and Dairy-Free: Ensure Worcestershire is gluten-free or use tamari + a splash of balsamic. Swap butter for olive oil and skip cheese or use a melty dairy-free option.

Can I use pre-cooked rice?

Yes—turn this into a skillet version. Caramelize onions, add garlic and seasonings, then stir in 3 cups cooked rice and 1/3 cup broth.

Simmer until absorbed, finish with cheese, and serve.

What onions are best?

Yellow onions strike the perfect balance of sweetness and savor. White onions can work but are sharper; sweet onions caramelize faster but can be a bit one-note, so boost with extra thyme and a pinch of salt.

Do I have to use cheese?

Nope. It’s still rich and aromatic without it.

If you want a dairy-free pop, finish with toasted breadcrumbs tossed in olive oil and garlic—crunchy and satisfying.

Why is my rice mushy?

Likely too much liquid or overbaking. Measure carefully, rinse rice, and bake just until liquid is absorbed. Resting 5–10 minutes post-bake helps the grains set.

Can I make it on the stovetop only?

Yes.

After toasting the rice and adding liquid, cover and simmer on low 15–18 minutes. Keep the lid on—peeking vents steam and messes with the texture, IMO.

The Bottom Line

French onion rice is the weeknight flex that tastes like a weekend project. Caramelized onions, cozy herbs, and fluffy rice team up for an outrageously satisfying dish with almost no drama.

Dress it up with Gruyère, keep it simple and veggie-friendly, or make it a full meal—either way, it’s a guaranteed repeat. One bite and you’ll wonder why you ever settled for plain rice.
