Why You’ll Love This Recipe

I love this dish because it transforms a few pantry staples into something truly crave-worthy. The French onion soup mix gives it that deep, slow-cooked flavor without the time, and the butter adds richness that makes every bite melt-in-your-mouth good. It’s hands-off, budget-friendly, and goes with just about anything. Once I made it, I knew it would become a permanent favorite in my kitchen.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

Long grain white rice (uncooked)
French onion soup (canned or homemade)
Beef broth
Unsalted butter
Optional: sliced mushrooms, minced garlic, fresh parsley, shredded cheese

Directions

I preheat the oven to 350°F (175°C) and lightly grease a 9×9-inch baking dish.
I pour the uncooked rice evenly into the dish.
I add the French onion soup and beef broth over the rice, stirring gently to combine.
I place slices or cubes of butter evenly over the top.
I cover the dish tightly with foil and bake for 30 minutes.
I uncover and continue baking for another 25–30 minutes, or until the rice is tender and the top is golden.
I fluff with a fork and garnish with parsley or cheese before serving, if desired.

Servings and timing

This recipe makes about 4–6 servings and takes around 1 hour total to prep and bake.

Variations

I sometimes add sautéed mushrooms or onions for even more depth.
Swapping beef broth for vegetable broth works great if I want a lighter flavor.
I’ve stirred in shredded mozzarella or Swiss cheese for a cheesy twist.
A dash of Worcestershire sauce or soy sauce adds extra umami.

Storage/Reheating

I store leftovers in an airtight container in the fridge for up to 4 days. To reheat, I use the microwave or warm it in the oven with a splash of broth to bring back the moisture. It also freezes well—I portion it into freezer bags for easy sides later on.

FAQs

Can I use brown rice?

Yes, but I increase the liquid slightly and bake it longer—up to 90 minutes, covered the whole time.

Is this dish vegetarian?

It can be if I use vegetarian French onion soup and broth. The flavor is still amazing.

Do I need to rinse the rice?

I usually don’t for this recipe, since the starch helps give the dish a creamy texture—but I can if I prefer fluffier grains.

Can I make this in advance?

Yes, I assemble it ahead and bake it when ready, or I fully bake it and reheat it later—it holds up great.

What should I serve this with?

I love serving it with roasted chicken, grilled meat, or even just a green salad for a simple, satisfying meal.

French Onion Butter Rice is a cozy, flavorful side dish I can count on any time I want something warm, rich, and easy. With minimal prep and bold flavor, it’s the kind of recipe that turns basic ingredients into something irresistible.
