Creamy Chicken Pot Pie Soup with Puff Pastry Crackers
This chicken pot pie soup delivers all the comfort of the classic casserole in a velvety, thyme-flecked broth topped with shattered puff pastry crackers.
This chicken pot pie soup is the liquid embodiment of a warm hug. It captures everything you love about the classic baked casserole—the tender poultry, the sweet peas, and that silky gravy—but reimagines it as a bowl of pure, unadulterated comfort that comes together much faster than a traditional pie.
By using a roux-thickened broth and a splash of heavy cream, we create an easy chicken pot pie soup that feels decadent without being heavy. To solve the problem of the missing crust, we bake off shattered shards of puff pastry seasoned with flaky salt, providing that essential buttery crunch in every spoonful.
Whether you are looking for a cozy weeknight dinner or a crowd-pleasing lunch, this creamy chicken pot pie soup hits the mark. It’s a one-pot wonder that skips the fussy dough-crimping but keeps the soul-satisfying flavor profile of a Sunday roast.
Ingredients
Puff Pastry Toppers
- 1 sheet frozen puff pastry (approx. 245g), thawed but cold
- 1 large egg, beaten with 1 teaspoon water
- 1/2 teaspoon flaky sea salt
The Soup Base
- 4 tablespoons (56g) unsalted butter
- 1 large yellow onion, finely diced
- 3 medium carrots, peeled and sliced into 1/4-inch coins
- 2 stalks celery, diced
- 3 cloves garlic, minced
- 1/4 cup (32g) all-purpose flour
- 4 cups (960ml) low-sodium chicken stock
- 1 pound (450g) cooked chicken (rotisserie or poached), shredded
- 1 cup (150g) frozen peas
- 1 teaspoon dried thyme (or 1 tablespoon fresh)
- 1/2 cup (120ml) heavy cream
- Salt and freshly cracked black pepper to taste
Instructions
- 1
Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
- 2
Unfold the puff pastry sheet and cut it into irregular 2-inch shards or squares. Place them on the baking sheet, brush with the egg wash, and sprinkle with flaky salt. Bake for 10-12 minutes until golden brown and puffed, then set aside.
- 3
Melt the butter in a large Dutch oven or heavy-bottomed pot over medium heat.
- 4
Add the onion, carrots, and celery. Cook for 6-8 minutes, stirring occasionally, until the vegetables begin to soften and the onions are translucent.
- 5
Stir in the garlic and thyme, cooking for 1 minute until fragrant.
- 6
Sprinkle the flour over the vegetables and stir constantly for 2 minutes to cook out the raw flour taste; do not let it burn.
- 7
Slowly pour in the chicken stock while whisking or stirring vigorously to prevent lumps from forming.
- 8
Bring the soup to a gentle simmer and cook for 10 minutes, or until the carrots are fork-tender and the broth has thickened.
- 9
Fold in the shredded chicken and frozen peas. Stir for 2-3 minutes until the peas are bright green and the chicken is heated through.
- 10
Lower the heat and stir in the heavy cream. Season generously with salt and black pepper to taste.
- 11
Ladle the soup into bowls and top with several shattered puff pastry crackers immediately before serving.
Tips
- → Use a rotisserie chicken to save at least 20 minutes of prep time and add extra depth of flavor.
- → If the soup gets too thick upon standing (the flour continues to hydrate), simply thin it with a splash of chicken stock or milk.
- → Don't skip the thyme; it is the specific herb that gives the broth that nostalgic 'pot pie' aroma.
- → Wait to add the puff pastry crackers until the very second you serve to keep them from getting soggy.
FAQ
Can I make chicken pot pie soup in a slow cooker?
Yes. Add all ingredients except the flour, cream, peas, and puff pastry to the slow cooker. Cook on low for 6 hours. Thirty minutes before serving, whisk the flour with some cream to create a slurry, stir it in with the peas, and cook on high until thickened.
How do I store and reheat leftovers?
Store the soup in an airtight container in the fridge for up to 4 days. Store the puff pastry crackers in a dry container at room temperature. Reheat the soup on the stovetop over low heat, adding a splash of broth if needed.
Why does my chicken pot pie soup look curdled?
This usually happens if the soup is boiling vigorously when the cream is added. Always lower the heat to a bare simmer before stirring in dairy to ensure a smooth, velvety texture.
