Chicken and Mushroom Pot Pie Soup

Ingredients

• 1 pound of chicken breast cut into bite-size pieces
• 1 tablespoon neutral oil
• 1 pound of oyster mushrooms pulled apart in small bunches
• 4 tablespoons of butter, plus 1 tablespoon for brushing;
• 3 carrots - chopped
• 4 ribs of celery - chopped
• 1 large yellow onion - chopped
• 4 cloves of garlic - sliced
• 1 teaspoon of fresh thyme - chopped
• 1/3 cup All-Purpose flour
• 6 cups of chicken stock at room temperature
• 1/2 lb gold Peewee potatoes;
• 1/2 cup frozen peas
• 1/2 cup heavy cream
• 1 small punch of parsley chopped (roughly 1/4 to 1/2 cup)
• 1 puff pastry sheet
• Flaky sea salt
• Salt and pepper to taste

Directions

1. Preheat the oven to 450 degrees F.
2. Season the chicken with salt and pepper. In your All-Clad D3 Weeknight Pan, heat 1 tablespoon of neutral oil over medium heat. When the oil is hot, add the chicken and sear the pieces for 3 to 4 minutes per side. Remove and reserve. Add the oyster mushrooms and repeat this process. After the mushrooms are golden, season with salt and pepper and put to the side.
3. Lower the heat of the pan to medium-low. Add the butter and melt. Add the carrots, celery, and onion. Saute for 5 minutes until softened and onions are translucent. Add the garlic and thyme and continue to cook for an additional minute or until very fragrant.
4. Add the mushrooms back to the pan, add the flour, and mix to combine with all the ingredients in the pan. Pour in the room temperature stock, stirring as you pour. Season with salt and pepper. Add the potatoes and chicken back to the pan. Bring to a boil then reduce to a simmer. Cover and cook for 15 minutes or until the potatoes are tender.
5. Remove lid and taste, adjusting the salt and pepper if needed. Add the frozen peas, heavy cream, and 1/4 cup of parsley. Let simmer for an additional 5 minutes.
6. Roll the puff pastry over the pan. Using a fork, poke holes into the pastry. Brush the pastry with the melted butter and bake for 5 to 10 minutes or until the pastry is cooked and golden brown. Remove from the oven. Garnish with flaky sea salt and serve.

Pro Tips

You can skip the pastry part if desired. The soup will be thick and creamy, just like the inside of a chicken pot pie.  Replace the oyster mushrooms for other traditional style of mushrooms such as the cremini or button mushroom.  Freeze the leftovers in single portions for your next quick weeknight meal. 

How do you Make the Best Chicken Pot Pie Soup? Key Ingredients and Flavor Tips

The best chicken pot pie soup starts with building layers of flavor. Begin by searing the chicken and mushrooms to develop depth, then sauté aromatics like onion, carrot, celery, and garlic until softened and fragrant. This creates a rich base before adding stock and letting everything simmer together.

A few key elements make the difference:

• Use a good-quality chicken stock for a fuller, more developed flavor
• Add flour at the right moment to create a smooth, lightly thickened texture
• Simmer until the potatoes are tender so the soup feels hearty and balanced
• Finish with cream, butter, and fresh herbs for richness and brightness

When these components come together, the result is a soup that captures everything you love about chicken pot pie—comforting, creamy, and deeply flavorful.

How do you Cook Chicken Pot Pie Soup With or Without Cream? Gluten-Free, Keto, and Lighter Variations to Try

Chicken pot pie soup is naturally rich and comforting, but it’s also easy to adapt based on your preferences. For a classic version, adding heavy cream toward the end of cooking creates a smooth, velvety texture that brings all the flavors together. If you prefer a version without cream, the soup can still feel hearty and satisfying thanks to the combination of sautéed vegetables, flour, and a well-developed stock.

You can also adjust the recipe to fit different needs without losing its signature comfort:

• Without cream: Let the soup simmer a bit longer to thicken naturally, or finish with a small amount of butter for added richness
• Lighter option: Use milk or half-and-half instead of heavy cream, and slightly reduce the butter for a more balanced feel
• Gluten-free: Substitute the flour with a gluten-free blend or a cornstarch slurry to maintain a smooth, thick consistency
• Keto-friendly (without milk): Skip the flour and rely on reduction or a small amount of cream cheese for body, focusing on chicken, mushrooms, and lower-carb vegetables

You can also:

• Let the soup reduce slightly longer for a thicker texture
• Add a small amount of extra butter for a rounded finish

With a few simple adjustments, you can tailor this recipe to your cooking style while still enjoying the same warm, homemade flavors that make chicken pot pie soup so satisfying.

Can You Use Turkey Instead of Chicken? Easy Substitutions for the Recipe

Yes—turkey is an excellent substitute for chicken in this recipe and works especially well if you have leftovers on hand. Its mild flavor and tender texture pair naturally with the creamy broth, vegetables, and herbs, creating a result that feels just as comforting and satisfying.

A few simple adjustments can help you get the best results:

• Use cooked turkey: Since it’s already prepared, add it toward the end of cooking to prevent it from drying out
• Adjust seasoning as needed: Turkey can be slightly leaner, so a touch more salt, butter, or herbs can help round out the flavor
• Keep the same cut size: Chop or shred the turkey into bite-sized pieces so it blends evenly with the vegetables and broth

This swap makes the recipe especially versatile—perfect for turning leftover turkey into a warm, homemade meal that feels just as rich and flavorful as the original.
