Note: I’ve bumped up the amount of broth based on comments from people who found their rice undercooked.
Heat a large sauté pan, preferably one with a lid, over medium-high heat for one minute. Once the pan is very hot, add 1 tablespoon olive oil and 1 tablespoon butter, and heat them together for another full minute. Arrange chicken skin side down and cook until deeply brown underneath, about 4 to 5 minutes. [Don’t crowd the chicken; depending on the size of your pan, you might need to do this in two batches.] While it browns, season what is now the top side with additional salt and pepper. Once browned, flip the pieces over and brown on the second side, about another 3 to 4 minutes. Don’t skimp on the color, please. Transfer the chicken to a plate.
Prepare the buttered onions: Leave the pan on medium-high and add 2 tablespoons butter to fat and juices in it. Once melted, add the onions and season with 1 teaspoon kosher salt. Cook the onions for about 15 minutes total, or until golden throughout and darker brown at the edges, stirring every couple minutes. In the beginning, the onions are watery; once the water has cooked off and the onions begin to pick up color, I reduce the heat to medium for the remaining time. Carefully taste and season with more salt, if desired, and lots of freshly ground black pepper. Remove 1/3 cup of onions and set aside until the end.
Finish the chicken and rice: Add thyme and dried rice and cook with the onions for 1 minute. Add the wine, if using, and cook until it disappears, about 1 to 2 minutes. Scrape down the pan sides, pushing any dried rice and onions back to the bottom. Return the chicken thighs to the pan skin side up, spacing them out. Carefully pour 2 cups (updated amount) of the broth around chicken. Bring the pan to a simmer then reduce to the lowest simmer and cover. Cook rice and chicken together for 25 minutes, or until rice is tender. If rice is not tender at 25 minutes, add remaining 1/4 cup broth and return to the heat for another 5 to 10 minute4s.
To finish and serve: Off heat, rest the dish for 5 to 10 minutes before serving. Scatter with reserved buttered onions and scoop it onto plates.
Do ahead: This keeps so well. I reheat it covered in an oven-safe dish at 350 degrees for 15 to 30 minutes, until the chicken is warm. To freeze, well, I’m just going to say it: I’ll pack it ingloriously in a freezer bag and press out the extra air. Defrost in the fridge for a day, if you have time, then rewarm as written above.
Notes/anticipated questions:
- Can I use different bone-in, skin-on chicken parts? Yes. Larger chicken breasts can take longer to cook. Look for ones on the smaller side (8 ounces). If they’re larger, I’ll sometimes split them in half so that they cook through by the time the rice is done.
- Can I use boneless, skinless chicken cutlets? Yes. I’d use thighs since they’re less likely to dry out, and even though it won’t be as pretty, I’d probably skip browning them so they don’t overcook by the time the rice is done.
- What can I use instead of wine? I’d use 2 tablespoons white wine vinegar and 1/4 to 1/2 teaspoon sugar.
- Can I make chicken rice with buttered onions without butter? Yes, olive oil or another fat will work fine, but of course a key part of the flavor will be different.
- How do I make this even more buttery? When the chicken and rice are done but haven’t rested yet, dot the dish with 1 to 2 additional tablespoons butter, cut into small bits, then replace the lid and let it rest for the 5 to 10 minutes suggested.
- A better than bouillon concentrate hack: The best chicken broth is homemade. My second favorite comes from Better Than Bouillon. The jar instructions are to add 1 teaspoon per 1 cup of hot water before using it but I am lazy and add the concentrate directly to aromatics in the pan — here, along with the thyme and dried rice — and cook it in for a minute to distribute the blob of concentrate. Then I add measured water when the recipe calls for broth.
- Note: The thyme inside the dish is for flavor; the thyme on top is for aesthetics on a very brown dish.
