Why You’ll Love This Buttery Onion Rice

You’ll love this buttery onion rice because it combines the best of both worlds: comfort and elegance. It’s quick to put together, budget-friendly, and packed with flavor. The caramelized onions give it a subtle sweetness and depth while butter coats each grain of rice in a delicate richness. It’s a side dish you’ll come back to time and time again.

Can I Use Brown Rice Instead?

You absolutely can use brown rice if you prefer. Just keep in mind that brown rice takes longer to cook and may need more liquid. The nutty taste of brown rice pairs beautifully with the onions and butter, making it a wholesome yet still indulgent option.

Ingredients for the Buttery Onion Rice

Rice is the foundation of this dish, offering fluffy, tender texture that soaks up all the buttery flavor. You’ll need onions, which add sweetness and depth after being slowly sautéed. Butter is what makes this rice truly irresistible, creating richness and a silky mouthfeel. A bit of salt enhances all the flavors while broth (chicken or vegetable) gives the rice more dimension than water alone.

How To Make the Buttery Onion Rice

Step 1: Prepare the Onions

Start by thinly slicing your onions. In a large skillet or saucepan, melt butter over medium heat. Add the onions and sauté them slowly until they’re golden and caramelized, about 10–15 minutes.

Step 2: Toast the Rice

Once the onions are soft and fragrant, add your uncooked rice to the pan. Stir it into the onions and butter, letting it toast for 1–2 minutes. This adds a nutty flavor to the rice.

Step 3: Add Broth and Simmer

Pour in warm broth, stir, and bring the mixture to a gentle boil. Lower the heat, cover the pan, and let it simmer until the rice is tender and the liquid is absorbed. This usually takes about 15–20 minutes for white rice.

Step 4: Fluff and Serve

Remove from heat and let the rice sit covered for a few minutes. Then fluff it with a fork, sprinkle with a bit more melted butter if you’d like, and serve warm alongside your favorite main course.
