This one pot creamy chicken and mushroom soup is my secret weapon for turning a dreary Tuesday into something special. It’s the kind of meal that makes everyone wander into the kitchen, drawn by the smell of herbs and browning chicken. My daughter, who usually pushes mushrooms to the side of her plate, asked for a second bowl last week. Here’s why this recipe works: we build layers of flavor right in the pot, starting with golden chicken and ending with a silky, herb-infused broth that feels rich without being heavy.
It’s a true one-pot wonder. You get that slow-simmered taste without the hours of waiting or the mountain of dishes. The key is patience in the first few steps—letting the chicken get a proper sear and the mushrooms release all their earthy juices. That liquid gold becomes the base of your soup. Trust me, it makes all the difference.

Why You’ll Love This One Pot Chicken and Mushroom Soup
First, the cleanup is practically non-existent. Everything happens in one sturdy pot. No juggling multiple pans or creating a sinkful of dishes. That alone makes it a weeknight hero.
Second, the texture is pure comfort. The soup is creamy and luxurious, but it doesn’t rely on a ton of heavy cream. A bit of flour and milk thicken it beautifully, creating a velvety base that clings to every piece of chicken and mushroom.
Finally, it’s incredibly adaptable. Don’t have fresh thyme? Use dried. Want it thicker? Let it simmer a few minutes longer. I’ll share my favorite variations below, including a fantastic way to use up leftover rice that turns this soup into a hearty meal.
Ingredients for Your One Pot Creamy Chicken and Mushroom Soup
- 1.5 lbs boneless, skinless chicken breasts, cut into 1-inch pieces
- 1 tbsp olive oil
- 1 tbsp butter
- 1 medium yellow onion, diced
- 3 cloves garlic, minced
- 1 lb cremini mushrooms, sliced (baby bellas work great)
- 1/3 cup all-purpose flour
- 4 cups chicken broth
- 1 cup whole milk
- 1/2 cup heavy cream
- 2 tsp fresh thyme leaves (or 3/4 tsp dried thyme)
- 1 tsp onion powder
- Salt and freshly ground black pepper to taste
- Chopped fresh parsley for garnish
A note on the mushrooms: Cremini mushrooms have a deeper, earthier flavor than white button mushrooms, which really elevates this one pot creamy chicken and mushroom soup. Don’t wash them under water—just wipe them clean with a damp paper towel to keep them from getting soggy.
Substitution tip: Out of heavy cream? You can use an additional 1/2 cup of whole milk mixed with 1 tablespoon of cornstarch. Add it at the very end and simmer for 2-3 minutes to thicken. For more simple ingredient swaps, I often turn to the guides over at Lilly’s Bites.
How to Make This One Pot Creamy Chicken and Mushroom Soup
- Brown the chicken. Pat your chicken pieces very dry with paper towels—this is crucial for getting a good sear. Heat the olive oil and butter in a large Dutch oven or heavy-bottomed pot over medium-high heat. Season the chicken generously with salt and pepper. Add it to the pot in a single layer, working in batches if needed. Let it cook undisturbed for 3-4 minutes per side, until you get a beautiful golden-brown crust. The sizzle should be steady and confident. Remove the chicken to a plate. It won’t be cooked through yet, and that’s perfect.
- Sauté the aromatics. In that same pot, you’ll now build the foundation for your one pot creamy chicken and mushroom soup. Add the diced onion. Cook for 3-4 minutes, stirring occasionally, until it starts to soften and turn translucent. The bottom of the pot will have lovely browned bits from the chicken—that’s flavor. Add the garlic and cook for just 30 seconds until fragrant. Don’t let it burn.
- Cook the mushrooms. Add all the sliced mushrooms to the pot. They’ll seem like a lot, but they’ll shrink down. Season with a pinch of salt. Cook, stirring occasionally, for 6-8 minutes. You want them to release their liquid and become deeply browned. This step is where the soup gets its soulful, umami depth. The kitchen will smell incredible.
- Make the roux. Sprinkle the flour over the mushroom mixture. Stir constantly for about 1 minute. The flour will coat everything and start to smell a bit nutty. This cooks out the raw flour taste and will thicken our soup beautifully.
- Simmer it all together. Slowly pour in the chicken broth while stirring constantly to avoid lumps. Scrape up any remaining browned bits from the bottom of the pot. Add the thyme and onion powder. Bring the mixture to a gentle boil, then reduce the heat to a simmer. Return the browned chicken (and any juices from the plate) to the pot. Let your one pot creamy chicken and mushroom soup simmer uncovered for 10-12 minutes, until the chicken is cooked through and tender, and the soup has thickened slightly.
- Finish with cream. Stir in the milk and heavy cream. Warm it through over low heat for another 3-4 minutes. Do not let it boil after adding the dairy. Taste and adjust seasoning with more salt and pepper if needed. The soup should be creamy, savory, and deeply satisfying. Ladle into bowls and garnish with a sprinkle of fresh parsley.
Tips & Variations for the Best Soup
Storage & Reheating: This soup keeps beautifully. Store cooled leftovers in an airtight container in the fridge for up to 4 days. The flavors meld and get even better. Reheat gently on the stovetop over low heat, stirring often. If it thickens too much in the fridge, add a splash of broth or milk when reheating.
Make it Heartier: Stir in 1 to 1.5 cups of cooked wild rice or egg noodles during the last 5 minutes of simmering in step 5. It transforms the soup into a complete, filling meal. If you love the chicken and wild rice combo, you must try my Creamy Chicken and Wild Rice Soup next.
For a Lighter Version: Substitute the heavy cream with an equal amount of additional whole milk or even half-and-half. The soup will be a little less rich but still wonderfully creamy.
Freezing: You can freeze this one pot creamy chicken and mushroom soup for up to 3 months. Cool completely and store in freezer-safe containers. Thaw overnight in the fridge before reheating. Note: The texture of the cream may separate slightly upon thawing, but a good stir during reheating will bring it right back together.
