Chicken Rice Casserole with Tender One-Pan Rice

• Rinsing long-grain rice removes loose surface starch. The grains stay more distinct instead of forming a sticky layer beneath the chicken.
• Hot stock begins hydration immediately, while tight foil prevents moisture loss. Together they make the stated bake time more dependable than cold liquid and a loose cover.
• Chicken thighs sit above the rice rather than being mixed through it. Their juices season the grains, and the exposed tops can brown during the uncovered finish.

Ingredient notes

• Long-grain rice: Use regular white long-grain rice, not instant, parboiled, or brown rice. Different processing changes both the liquid requirement and cooking time. Weigh it before rinsing for an accurate stock ratio.
• Chicken thighs: Boneless skinless thighs tolerate the long covered bake and remain tender. Choose pieces near 140 g each so the six portions cook at the same pace.
• Stock: Heat the stock before pouring it into the dish. Lower-sodium stock gives you control because the seasoned chicken contributes salt to the rice below.
• Onion and garlic: Dice the onion finely so it softens fully among the grains. Grated garlic disperses without leaving firm pieces after baking.
• Paprika butter: Melted butter carries paprika across the chicken and adds richness to the lean rice base. Brush it on after arranging the thighs to keep seasoning off the foil seal. Spread it thinly so no spice paste falls into one patch of rice.

1. 1Rinse and level the rice

   Heat the oven to 375°F (190°C). Rinse the rice in a fine sieve under cold water until the runoff looks nearly clear, then drain for 2 minutes. Spread rice, onion, garlic, thyme, and salt evenly in a 9-by-13-inch baking dish. Pour in the hot stock and stir once, making sure no dry grains cling above the liquid line.

   

2. 2Season and seal

   Arrange the thighs in one layer over the rice. Mix melted butter, paprika, garlic powder, salt, and pepper, then brush it over the exposed chicken. Cover the dish tightly with foil, crimping every edge. The seal matters more than a heavy lid because small gaps allow liquid to escape before the center grains soften.

3. 3Bake covered, then uncover

   Bake for 45 minutes without lifting the foil. Uncover carefully and check a spoonful of rice from the center. The grains should be almost tender with only a small amount of liquid visible. Bake uncovered for 10 to 15 minutes, until the chicken reaches 175°F (80°C), its top browns, and no broth pools along the sides.

   

4. 4Rest and fluff around the chicken

   Remove the dish and rest it uncovered for 10 minutes. Transfer the thighs briefly to a clean plate. Fluff the rice from the edges toward the center with a fork, separating any compacted spots without mashing the grains. Return the chicken, scatter with parsley, and divide into 6 servings, giving each plate both edge and center rice.

• Measure rice and liquid by weight. A casual scoop of rice can shift the ratio enough to leave hard grains.
• Drain rinsed rice well. Water held in the sieve is unmeasured liquid and can make the casserole soft.
• Use a metal or ceramic dish with straight sides. Very thick glass can extend the time needed for center rice.
• Crimp foil against the rim. A loose tent allows moisture to escape and leaves the top layer undercooked.
• Check rice from the center, not the edge. Outer grains soften first and can hide a firm middle until the final uncovered bake begins.

Add a green salad with a sharp vinaigrette or roast a tray of green beans on the lower rack during the uncovered finish. Each of the 6 portions already includes a substantial starch, so bread is unnecessary. Spoon parsley-flecked rice beside the thigh rather than covering the browned surface, and offer lemon wedges for anyone who wants extra brightness.
