Ingredients for chicken rice mushroom soup onion soup
Fourteen ingredients blend umami richness with comforting textures for a restaurant-worthy one-pot meal.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless, Skinless Chicken Thighs 🍗 | 1 ½ lb | Trimmed of excess fat |
| Yellow Onions 🧅 | 3 whole | Thinly sliced for caramelization |
| Cremini Mushrooms 🍄 | 8 oz | Sliced for earthy depth |
| Jasmine Rice 🍚 | 1 cup | Uncooked, long-grain preferred |
| Chicken Broth 💧 | 4 cups | Low-sodium preferred |
| Garlic Cloves 🧄 | 4 cloves | Minced for aromatic base |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For sautéing onions/mushrooms |
| Fresh Thyme 🌿 | 2 sprigs | Or 1 tsp dried thyme |
| Bay Leaves 🌿 | 2 whole | For subtle herbal complexity |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly cracked for brightness |
| Fresh Parsley 🌿 | ¼ cup | Chopped for garnish |
| Dry Sherry 🍷 | ½ cup | Or substitute white wine |
| All-Purpose Flour 🌾 | 1 tbsp | For velouté thickening |
The onions and mushrooms form the flavor foundation—yellow onions should be sweet, not bitter, and cremini mushrooms add meaty texture. Whole Foods or local farmers markets often carry the freshest varieties, but grocery store brands work fine if they're firm and vibrant. For the chicken, thighs stay juicier than breasts during long cooking. Costco or butcher shops typically offer the best price per pound for bone-in cuts, though boneless thighs save prep time. The jasmine rice should be long-grain for optimal texture, and Daybreak or Calrose varieties are ideal for soups.
No sherry? Dry white wine or extra chicken broth maintains the depth. Fresh thyme is preferable, but dried thyme at one-third the amount works in a pinch. The flour for thickening should be all-purpose, not cake flour—it creates a smoother velouté. For mushrooms, shiitake or oyster varieties add extra umami, while cremini provides a balanced earthiness. The garlic should be freshly minced, not pre-minced from jars, which can be rancid. If you're using pre-sliced mushrooms, pat them dry to avoid a watery broth.
Store any leftovers in an airtight container for up to 4 days—the flavors actually improve overnight as everything melds. For freezing, portion into single-serving containers and thaw in the fridge for even reheating. The rice will firm up when reheated, so add a splash of broth when warming. This soup reheats beautifully—simmer gently for 5-7 minutes on the stove or microwave for 2-3 minutes with a damp paper towel covering to retain moisture.

Step-by-step instructions for chicken rice mushroom onion soup
Transform simple ingredients into a rich, umami-packed soup where each element harmonizes perfectly.
Sear the Chicken Thighs for Deep Flavor
Pat the 1.5 lb boneless, skinless chicken thighs dry with paper towels and season generously with 1 tsp salt and 0.25 tsp black pepper. Heat 2 tbsp extra-virgin olive oil in a large Dutch oven over medium-high heat until shimmering. Add the chicken and sear for 6-8 minutes per side until golden brown and cooked through to 165°F internally.
Remove the chicken and set aside on a plate. The rendered fat in the pot will form the flavor base for your soup—don't wipe it out. This step creates the rich foundation that carries through every spoonful. If the oil smokes excessively, reduce heat slightly to maintain even browning without burning.
Caramelize Onions and Mushrooms for Umami Depth
In the same Dutch oven, add the 3 whole yellow onions sliced into thin rounds and 8 oz cremini mushrooms sliced into even pieces. Cook over medium heat for 12-15 minutes, stirring occasionally, until the onions turn deep golden brown and the mushrooms release their moisture and caramelize. This slow cooking process develops their natural sweetness and umami.
After 8 minutes, add the 4 minced garlic cloves and 2 sprigs fresh thyme to the pot. Cook for an additional 1 minute until fragrant—this prevents the garlic from burning while infusing its aromatic oils into the mixture. The onions should be soft enough to pierce with a fork but still maintain some texture.
Build the Velouté Base with Rice and Broth
Sprinkle the 1 tbsp all-purpose flour evenly over the onion-mushroom mixture and stir vigorously for 1 minute to coat all the ingredients. This creates a roux that will thicken your soup beautifully. Immediately pour in the 4 cups chicken broth and 0.5 cup dry sherry, scraping up any browned bits from the bottom of the pot.
Bring the mixture to a gentle simmer over medium heat, then add the 1 cup jasmine rice and 2 whole bay leaves. Stir once to distribute the rice evenly. The rice will absorb the liquid as it cooks, creating a creamy texture without requiring separate thickening. Simmer uncovered for 15 minutes, stirring occasionally, until the rice is tender but still has a slight bite.
Finish with Chicken and Seasoning
Return the seared chicken thighs to the pot, breaking them into bite-sized pieces with two forks. Add the remaining 0.5 tsp salt and 0.25 tsp black pepper to balance the flavors. Simmer for an additional 5 minutes to ensure the chicken absorbs the rich soup flavors and reaches a safe internal temperature throughout.
The soup should now have a velvety consistency with distinct layers of flavor—sweet caramelized onions, earthy mushrooms, aromatic thyme, and tender chicken. Taste and adjust seasoning if needed, remembering that the rice will continue to absorb liquid as it rests. Remove and discard the bay leaves before serving.
Pro Tips For Making Chicken Rice Mushroom Soup Onion Soup
- Sear Chicken First: I learned this the hard way—skipping the sear means flavorless broth. Pat those chicken thighs very dry, then hit them with a screaming-hot pan (no oil needed—the fat will render). Let them brown for 4-5 minutes per side before pulling them out; that crust is where the soup’s depth lives.
- Slice Onions Thinly: Thick onion chunks turn mushy in broth. Grab a sharp knife and cut those yellow onions into paper-thin half-moons—almost translucent. They’ll soften beautifully without disappearing into the soup, and the texture stays pleasant. (Yes, even if you’re impatient like me.)
- Don’t Overcrowd the Mushrooms: After burning three batches of cremini mushrooms, I finally figured out: cook them in batches. A crowded pan steams them instead of searing, and you end up with sad, waterlogged mushrooms. Work in two batches, 3-4 minutes each, until they’re golden and the liquid’s mostly evaporated—then toss them into the soup.
- Toast the Rice Separately: This isn’t the prettiest method, but it’s the tastiest. Toast your jasmine rice in a dry pan for 2-3 minutes until fragrant—it’ll deepen the nutty flavor and prevent a gummy texture later. Then rinse it thoroughly before adding to the broth. (Your future self will thank you.)
Flavor customization for chicken rice mushroom soup onion soup
Sweet vs. Spicy
Balance the caramelized onions' natural sweetness with a touch of heat by adding ½ tsp smoked paprika when searing mushrooms. For a sweeter profile, stir in 1 tbsp honey during the final 5 minutes of simmering.
I find a ½ tsp cayenne sprinkled on top adds just enough kick without overpowering the umami depth. 🌶️
Umami Boosters
Elevate the earthy notes with 1 tbsp soy sauce or 1 tsp fish sauce (for vegetarians, use 1 tsp mushroom powder). Add these with the broth to amplify the savory depth.
I also love adding 2 slices of bacon, crisped separately and crumbled in at the end for smoky richness. 💛
Herbal Variations
Swap thyme for 1 sprig rosemary (finely chopped) for a piney aroma or add ½ tsp ground coriander for a citrusy twist. Fresh basil at the end brightens the dish—just toss in ¼ cup chopped basil during the final 2 minutes of simmering.
The herbs should complement, not compete, with the dominant umami flavors.
Texture Contrasts
Add crunch with toasted bread croutons (½ cup) or crispy fried shallots (2 tbsp) for texture. For creaminess, stir in ¼ cup coconut milk during the last 5 minutes—it blends beautifully with the velouté base. I also like adding ½ cup cooked quinoa for extra heartiness and protein. ✨
Regional Twists
For a Thai-inspired version, add 1 tbsp red curry paste with the broth and garnish with cilantro and lime wedges. A French bistro twist uses ½ cup Gruyère cheese stirred in at the end for a rich, melty finish.
The key is adjusting seasonings to match the new flavor profile while keeping the core technique intact.
Vegetarian Adaptations
Replace chicken with 14 oz extra-firm tofu (pressed and cubed) or 12 oz king oyster mushrooms (sliced thick). Boost umami with 1 tsp miso paste added to the broth. The mushrooms will absorb flavors beautifully, creating a satisfying "meaty" texture. 💪

Frequently asked questions
Can I use chicken breasts instead of thighs?
Chicken breasts will work, but thighs stay juicier during the long simmer. If using breasts, cut them into 1-inch cubes and sear them for only 4-5 minutes per side to avoid drying out. Add them back to the pot during the final 5 minutes of cooking to maintain tenderness.
How do I prevent the rice from turning mushy?
Use jasmine rice (or long-grain white rice) and stir it just once after adding to the broth. The rice should cook in 15 minutes—if it feels too soft, reduce simmering time slightly. For extra insurance, rinse the rice before adding it to the pot to remove excess starch.
What can I do if my soup is too thin?
Mix 1 tbsp flour with 2 tbsp cold water to create a slurry, then stir it into the simmering soup. Let it cook for 3-5 minutes until thickened. Alternatively, mash a few cooked rice grains against the pot's side to release starch and naturally thicken the broth.
Can I make this soup in an Instant Pot?
Yes! Sauté the chicken, onions, and mushrooms as directed, then add all remaining ingredients (including rice) and cook on high pressure for 8 minutes. Quick-release the pressure, then let it sit for 5 minutes before opening. The rice may need an extra 2-3 minutes of off-heat resting to finish cooking.
What's the best way to reheat leftovers?
Reheat gently on the stove over low-medium heat for 5-7 minutes, stirring occasionally and adding 2-3 tbsp broth or water if needed. For microwave reheating, cover with a damp paper towel and heat for 2-3 minutes at 50% power. Never fully reheat rice to 165°F—just warm through to 140°F for safety.
