A creamy chicken pot pie soup with cooked chicken, mushrooms, mixed vegetables, potatoes, and a lightly thickened milk broth.
Chicken pot pie soup keeps the creamy filling idea of a pot pie but skips the pastry. This version uses cooked chicken, mushrooms, mixed vegetables, potatoes, and a milk-based broth thickened with cornstarch.
It is a practical weeknight soup because the chicken is already cooked and the vegetables are straightforward. The result is creamy and filling without needing a heavy roux or a long simmer.
Cornstarch thickens the broth quickly, which keeps the method simple. The milk adds body, while chicken broth and bouillon give the soup enough savoury depth to carry the vegetables.
Mushrooms help the soup taste fuller, and thyme gives it the familiar pot pie flavour. Potatoes add body and make the soup feel like a complete bowl rather than a thin chicken soup.
Rotisserie chicken or leftover roast chicken both work well. If using salted store-bought chicken or broth, taste before adding extra salt because the bouillon cubes also bring seasoning.
Frozen mixed vegetables keep this quick, but fresh carrots, peas, green beans, or corn can be used if you have them. Red potatoes hold their shape well; dice them small so they cook through quickly.
Whisk the broth, cornstarch, and milk in the pot before the soup gets too hot. This helps prevent lumps and gives the base an even texture.
Add the cooked chicken, celery, onion, mushrooms, bouillon, thyme, seasoning, and frozen vegetables. Simmer until the vegetables begin to soften, then add the potatoes and cook until tender.
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat gently over medium-low heat and add a splash of milk or broth if the soup has thickened too much.
Freezing is possible, but the potatoes and milk base can change texture. If you plan to freeze it, leave out the potatoes and add freshly cooked potatoes when reheating.
One bowl gives a high-protein main with vegetables and potatoes already built in. Serve it with whole-grain toast, biscuits, or a green salad depending on how substantial you want the meal to be.
For a lighter bowl, use 2% milk and keep the bread side small. For a richer version, use whole milk or finish with a small splash of cream.
