Why You’ll Love This Recipe

The real game-changer here is the puff pastry croutons. They deliver the essential flaky, buttery texture of a real pie crust that’s often missing from other soup recipes.

Ingredients Needed

Here is exactly what you’ll need for this recipe. For best results, I recommend using the quantities and ingredients as listed below.

• 4 tablespoons salted butter
• 1 cup small-diced carrot
• 1 cup small-diced celery
• 1 cup small diced onion
• 2 cloves garlic, minced
• ¼ cup all-purpose flour
• 4 cups chicken stock
• 1 ½ cups small diced Yukon gold potatoes
• 1 bay leaf
• ½ teaspoon dried thyme
• ½ teaspoon black pepper
• 2 cups cooked diced or shredded chicken
• ½ cup heavy cream
• 1 cup frozen peas
• ½ cup frozen corn
• Biscuits for serving
• fresh chopped parsley for garnish ((optional))

Ingredient Notes & Substitutions

Chicken: A store-bought rotisserie chicken is a fantastic time-saver for this recipe! You can also use leftover cooked chicken, or quickly poach or bake a couple of chicken breasts. I’ve included simple instructions for that below.

Potatoes: I highly recommend Yukon Gold potatoes for this soup. Their waxy texture holds its shape well during cooking and contributes to the creamy consistency. If you don’t have them, Russet potatoes are a good substitute.

Heavy Cream: For that signature rich and creamy texture, heavy cream is best. For a lighter version, you can substitute half-and-half or even whole milk, though the soup will be slightly less decadent.

Vegetables: The classic mirepoix of carrots, celery, and onion creates the perfect flavor base. Feel free to add other vegetables like chopped green beans or pearl onions along with the frozen peas and corn at the end.

For a Gluten-Free Soup: To make this soup gluten-free, you can easily substitute the all-purpose flour with a 1-to-1 gluten-free flour blend. Alternatively, you can thicken the soup with a cornstarch slurry. See the “Variations” section for detailed instructions.

How to Make Chicken Pot Pie Soup

This simple stovetop soup comes together in a single pot, making both cooking and cleanup a breeze.

1. Build the Flavor Base

In a large Dutch oven or stockpot, melt the butter over medium heat. Add the carrot, celery, and onion. It’s important to let this mirepoix cook for a full 10 minutes, stirring occasionally, until the vegetables are truly softened and just beginning to brown. This step builds a deep, savory foundation. Add the minced garlic and cook for just 30 seconds more, stirring constantly until it’s wonderfully fragrant.

2. Create the Roux

Sprinkle the all-purpose flour over the vegetables and stir continuously for about one minute. The flour will coat the vegetables and form a thick paste, which is called a roux. Cooking the flour is a crucial step to eliminate any raw, starchy taste and is the key to a perfectly thick soup.

3. Add Liquids and Simmer

Slowly pour in the chicken stock while stirring to prevent any lumps from forming. Add the diced potatoes, bay leaf, dried thyme, and black pepper. Bring the mixture to a boil, then reduce the heat to low, cover, and let it simmer for about 15 minutes. Stir it every so often to make sure nothing sticks to the bottom.

4. Finish the Creamy Soup

Once the potatoes are tender (a fork should pierce them easily), it’s time to finish the soup. Stir in the cooked chicken, heavy cream, frozen peas, and frozen corn. Bring the soup back to a gentle simmer and cook for another 5 minutes, just until everything is heated through. Be sure to find and discard the bay leaf before serving!

5. Season to Perfection

Once the soup is finished, give it a taste. The saltiness of chicken stock can vary widely by brand, so now is the perfect time to add salt and more pepper until the flavors are just right for you.

How to Prepare Chicken & Recipe Variations

This section covers the most common questions about preparing the chicken and adapting the recipe to your needs.

Three Easy Ways to Get Cooked Chicken

• Rotisserie Chicken: This is the fastest and easiest method! Simply pull the meat from a store-bought rotisserie chicken and shred or dice it. You’ll need about 2 cups.
• Poached Chicken: Place two boneless, skinless chicken breasts in a saucepan and cover with water or chicken broth. Bring to a simmer and cook for 15-20 minutes, or until cooked through. Remove and shred or dice.
• Baked Chicken: Preheat your oven to 400°F (200°C). Season two chicken breasts with salt, pepper, and olive oil. Bake for 20-25 minutes, or until the internal temperature reaches 165°F (74°C). Let rest before dicing.

Slow Cooker & Gluten-Free Options

Slow Cooker Instructions: For a hands-off approach, you can adapt this for a slow cooker. Sauté the mirepoix and make the roux on the stovetop as directed in steps 1 and 2. Transfer this mixture to your slow cooker. Stir in the chicken stock and potatoes. Cook on low for 4-6 hours or on high for 2-3 hours, until the potatoes are tender. During the last 30 minutes of cooking, stir in the heavy cream, cooked chicken, and frozen vegetables.

How to Make Gluten-Free Chicken Pot Pie Soup: You have two great options. First, you can replace the all-purpose flour with your favorite 1-to-1 gluten-free flour blend to make the roux. Second, you can skip the flour entirely and thicken the soup at the end. To do this, mix 2 tablespoons of cornstarch with 2 tablespoons of cold water to create a slurry. Stir the slurry into the simmering soup and cook for a minute or two until it thickens.

Pro Tips & Troubleshooting

Here are a few of my favorite tips and tricks from my kitchen to yours, ensuring your soup turns out perfectly every time.

Pro Tips for the Best Soup

• Deeper Flavor Base: Don’t rush sautéing the carrots, celery, and onion. Letting them get truly soft and slightly browned builds a huge amount of foundational flavor for the entire soup.
• For an Extra-Thick Soup: If you prefer your soup almost as thick as a pie filling, create a cornstarch slurry (2 tbsp cornstarch + 2 tbsp cold water) and stir it in at the end while the soup is simmering.
• Creamy Potatoes: Stick with Yukon Gold potatoes if you can. Their waxy, buttery texture holds up well in the soup and adds to the overall creaminess without becoming mealy.
• Puff Pastry Perfection: For the best croutons, make sure your puff pastry is very cold before cutting and baking. This helps it achieve the maximum, most impressive puff.

Common Mistakes to Avoid

• Forgetting the Bay Leaf: It adds a lovely, subtle background flavor, but it’s not meant to be eaten. Always remember to find and discard the bay leaf before you serve the soup.
• Raw Flour Taste: Be sure to cook the flour for at least a full minute after adding it to the pot. This crucial step cooks out any starchy, raw flavor from the roux.
• Burnt Garlic: Garlic can go from fragrant to burnt in seconds. Add it only in the last 30 seconds of sautéing the vegetables, just until it becomes aromatic.

Serving & Storage

This soup is a complete meal in a bowl, especially with the right toppings. Here’s how I love to serve and store it.

Serving Ideas

The absolute best way to serve this chicken pot pie soup is with homemade puff pastry croutons. They are incredibly easy to make!

1. Cut one sheet of thawed puff pastry into 1-inch squares.
2. Brush the squares with a beaten egg wash and sprinkle with flaky sea salt and a little dried thyme.
3. Bake at 400°F (200°C) for 10-12 minutes, or until golden brown and puffed up.

Of course, classic biscuits (canned or homemade) are always a wonderful choice. You can also serve it with pie crust crackers or simply garnish with a sprinkle of fresh chopped parsley for a touch of freshness.

Storage, Freezing, and Reheating

To Store: Let the soup cool completely, then transfer it to an airtight container. It will keep beautifully in the refrigerator for up to 4 days.

To Freeze: While you can freeze this soup, be aware that dairy-based soups can sometimes have a slight change in texture upon thawing. For the best results, let it cool completely and freeze in an airtight container for up to 3 months. Thaw overnight in the refrigerator before reheating.

To Reheat: Gently reheat the soup on the stovetop over medium-low heat, stirring occasionally until it’s warmed through. It’s best to avoid boiling, as this can sometimes cause the cream to separate.
