One-Pan Chicken with Mushrooms and Onions

Watch the Full Step-by-Step
- Large pan
- Chef's knife
INGREDIENTS
- 2.2 pounds/1 kilogram boneless chicken thighs
- 3 medium yellow onions, thinly sliced
- 8 ounces/225 grams mushrooms, sliced
- 2 tablespoons olive oil, plus more as needed
- 1½ tablespoons paprika
- ½ teaspoon ground turmeric
- 1 teaspoon black pepper
- 1 tablespoon salt
- 3 tablespoons date syrup
- 3 cups water, or as needed to just cover the chicken
INSTRUCTIONS
- Heat the olive oil in a large Dutch oven or heavy pot over medium-high. Add the chicken and cook until lightly browned on both sides, 2 to 3 minutes per side. Sprinkle with ½ teaspoon of the paprika, the turmeric and a pinch of the black pepper. Transfer to a plate.
- Reduce the heat to medium. Add a little more oil, if needed, then add the onions and mushrooms. Cook, stirring occasionally, until the onions are very soft and lightly caramelized and the mushrooms have released their liquid, 12 to 15 minutes.
- Return the chicken and any accumulated juices to the pot. Stir in the remaining paprika, the remaining black pepper, the salt and the date syrup. Pour in enough water to just cover the chicken and bring to a gentle simmer.
- Cover, reduce the heat to low and cook until the chicken is tender and the sauce has reduced slightly, 30 to 40 minutes. Taste and adjust the seasoning before serving.
- Serve over rice, mashed potatoes or with crusty bread.

FAQ
How do you keep chicken with mushrooms and onions from drying out?
Chicken thighs contain more fat and connective tissue, which helps them stay tender during simmering. Browning the chicken briefly at the beginning develops flavor without fully cooking the meat, allowing it to finish gently in the sauce. Avoid boiling the stew vigorously, as rapid boiling can tighten the meat fibers and make the chicken less juicy.
Keeping the chicken partially submerged in the cooking liquid also helps maintain moisture throughout the cooking process. Covering the pot traps steam and reduces evaporation, while cooking over low heat allows the chicken to become tender without overcooking. If using an instant-read thermometer, remove the chicken once it reaches an internal temperature of 165°F (74°C). Letting the finished dish rest for a few minutes before serving also allows the juices to redistribute throughout the meat.
Can I make chicken with mushrooms and onions in a slow cooker?
Yes, chicken with mushrooms and onions adapts well to a slow cooker. For the best flavor, brown the chicken and cook the onions and mushrooms in a skillet before transferring everything to the slow cooker. This extra step develops caramelization that cannot be achieved inside the slow cooker alone and results in a much richer finished dish.
Cook on Low for 5 to 6 hours or High for 2½ to 3½ hours, depending on the size of the chicken pieces. Since slow cookers trap moisture, you may need less water than the stovetop version. If the sauce is thinner than desired at the end, remove the lid during the final 20 to 30 minutes or transfer the liquid to a saucepan and simmer until slightly reduced.

Can I use chicken breasts instead of thighs?
Chicken breasts are much leaner and cook more quickly, so they require closer attention to prevent them from becoming dry. Boneless, skinless breasts should be browned lightly, then simmered only until they reach an internal temperature of 165°F (74°C), which may take significantly less time than thighs.
For even cooking, slice large breasts in half horizontally or use smaller breasts of similar size. Reducing the simmering time to about 20 to 25 minutes is often sufficient, depending on thickness. Because breasts contain less fat, the sauce may also benefit from a drizzle of olive oil before serving for additional richness. If tenderness is the priority, boneless thighs remain the better choice for this recipe.
How do I know when the chicken is fully cooked?
The most reliable way to determine whether chicken with mushrooms and onions is fully cooked is by using an instant-read thermometer. Insert the thermometer into the thickest part of the chicken without touching the pot. The chicken is safe to eat once it reaches an internal temperature of 165°F (74°C). This method is much more accurate than relying solely on cooking time.
Visually, the chicken should no longer appear pink inside, and the juices should run mostly clear when pierced. Boneless thighs become especially tender after simmering and should be easy to cut with a fork while still remaining juicy. Cooking much longer than necessary is unlikely to harm thighs significantly, but it can eventually reduce the amount of sauce through evaporation.
Can I use dried mushrooms instead of fresh mushrooms?
Dried mushrooms can be used in chicken with mushrooms and onions, although they should be rehydrated before cooking. Place the dried mushrooms in hot water for about 20 to 30 minutes until softened, then drain and slice them if necessary. The soaking liquid can also be strained through a fine sieve or coffee filter and added to the pot for extra mushroom flavor.
Because dried mushrooms have a more concentrated taste, you typically need much less than fresh mushrooms. A small amount of dried porcini or shiitake can provide a deep, earthy flavor that complements the onions and paprika particularly well.

What type of mushrooms work best?
Cremini mushrooms are an excellent choice for chicken with mushrooms and onions because they have a rich, earthy flavor that holds up well during simmering. White button mushrooms are another good option and produce a milder flavor while remaining widely available and affordable. Baby bella mushrooms, which are simply younger cremini mushrooms, also work very well and develop a deep savory taste as they cook.
For a more complex flavor, you can combine several mushroom varieties such as shiitake, oyster, and cremini. Shiitake mushrooms add an especially meaty texture, although their stems should be removed because they remain tough after cooking. Slice mushrooms evenly so they cook at the same rate, and avoid overcrowding the pot if increasing the quantity, since excessive moisture can prevent proper browning before simmering.
Can I make chicken with mushrooms and onions without date syrup?
The date syrup adds a subtle sweetness that balances the savory spices and onions, but the recipe will still be successful without it. If you prefer a similar flavor profile, honey or maple syrup can be substituted in equal amounts, although each brings its own distinct taste.
Brown sugar can also be used by dissolving it into the cooking liquid. If you prefer a completely savory dish, simply omit the sweetener altogether. The onions naturally become sweeter as they caramelize, providing some balance without additional sugar. Taste the finished sauce before serving and adjust the seasoning if needed to maintain a well-rounded flavor.
Can I use bone-in chicken for chicken?
Yes, bone-in chicken works very well in chicken with mushrooms and onions and often produces an even richer sauce. Bone-in, skin-on thighs or drumsticks release collagen as they cook, adding body and depth to the cooking liquid. Brown the chicken well before simmering to develop additional flavor and crisp some of the skin.
Because bone-in pieces are larger, they generally require a longer cooking time than boneless thighs. Plan for 40 to 50 minutes of gentle simmering, or until the meat reaches an internal temperature of 165°F (74°C) and pulls easily from the bone. If using skin-on chicken, keep the skin above the liquid whenever possible to help it retain some texture.

What should I serve with chicken with mushrooms and onions?
Chicken with mushrooms and onions pairs well with a variety of simple side dishes that absorb the flavorful sauce. Steamed white rice is one of the most popular choices because its neutral flavor complements the savory chicken without competing with the spices. Mashed potatoes are another excellent option, creating a rich and comforting meal. Crusty bread can also be served alongside for dipping into the sauce.
For lighter sides, consider roasted green beans, steamed broccoli, asparagus, or a crisp green salad dressed with lemon vinaigrette. Buttered egg noodles also work well because they hold the sauce nicely. If serving for a larger gathering, roasted carrots or cauliflower provide additional vegetables while keeping the meal balanced and hearty.
Can I freeze chicken with mushrooms and onions?
Yes, chicken with mushrooms and onions freezes very well. Allow the dish to cool completely before transferring it to freezer-safe containers or heavy-duty freezer bags. Leave a small amount of space at the top of each container to allow for expansion during freezing. Properly stored, it will maintain its best quality for up to three months.
To thaw, place the container in the refrigerator overnight rather than thawing at room temperature. Reheat gently on the stovetop over medium-low heat until the chicken reaches 165°F (74°C). The mushrooms may become slightly softer after freezing, but the overall flavor remains excellent. If the sauce separates slightly during reheating, simply stir it until it becomes smooth again.
Why are my mushrooms watery?
Mushrooms naturally contain a high percentage of water, so releasing moisture during cooking is completely normal. To help them brown rather than steam, cook them over medium heat without overcrowding the pot. If too many mushrooms are added at once, they release moisture faster than it can evaporate, resulting in a softer texture.
Avoid washing mushrooms under running water for extended periods, as they absorb moisture quickly. Instead, wipe them clean with a damp paper towel or rinse them briefly and dry thoroughly. Continue cooking until most of the released liquid evaporates before moving on to the next step. This concentrates the mushroom flavor and prevents the finished sauce from becoming overly thin.
