Rinse the rice under cold running water until the water runs mostly clear (about 20–30 seconds). This removes excess surface starch so the cooked grains stay separate and not gluey.

Thinly slice the onion and mince the garlic. Keep ingredients ready near the stove: caramelizing onion and toasting rice happen quickly at key moments and having everything prepped prevents burning.

In a medium saucepan over medium heat, melt 2 tablespoons of the butter. Add the sliced onion and a pinch of salt. Cook, stirring occasionally, for 12–16 minutes until the onion is deep golden brown and sweet. Reduce heat if the edges start to burn. Slow, patient cooking develops caramelization (Maillard reaction) that gives the rice a rounded, savory-sweet backbone.

Push the caramelized onion to the side, add the remaining 2 tablespoons butter and, once melted, add the minced garlic. Sauté for 20–30 seconds until fragrant—do not brown the garlic or it will taste bitter. The warm butter captures the garlic aroma and carries it through the dish.

Add the drained rice to the pan and increase heat to medium-high. Stir and cook the rice for 1–2 minutes, coating every grain in the butter and lightly toasting them. Toasting drives off residual surface moisture and develops a nutty flavor and firmer texture in the finished rice.

Pour in the broth, add the bay leaf (if using), the 1 tsp kosher salt and 1/2 tsp black pepper. Stir once to distribute, then bring to a gentle boil. Turning the boil down to a steady simmer avoids violent bubbling that can break grains apart.

Cover the saucepan with a tight-fitting lid, reduce heat to the lowest setting, and simmer for 15 minutes without lifting the lid. Cooking undisturbed lets steam do the final work—lifting the lid releases heat and steam, which lengthens cooking time and can make rice gummy.

After 15 minutes, remove the pan from heat and let it rest, still covered, for 8–10 minutes. This resting period allows trapped steam to finish cooking the rice gently and for moisture to redistribute for fluffy separate grains.

Remove the bay leaf, then gently fluff the rice with a fork to separate grains. Taste and adjust seasoning. If you like, stir in an extra 1 tablespoon of butter for a glossy finish and richer mouthfeel.

Transfer to a warm serving bowl, garnish with chopped parsley, and serve. The contrast of sweet caramelized onion, mellow garlic, and buttery finish elevates simple rice into a centerpiece side.
