This low carb chicken and mushroom soup is a comforting and hearty dish perfect for any season. It's packed with flavor and nutrition, making it an ideal choice for those looking to maintain a healthy lifestyle without sacrificing taste. The combination of tender chicken breast, earthy mushrooms, and a creamy broth creates a satisfying meal that will warm you from the inside out.
If you don't usually stock heavy cream or dried thyme in your pantry, you might need to pick these up at the supermarket. Heavy cream adds a rich, velvety texture to the soup, while dried thyme brings a subtle, aromatic flavor that complements the other ingredients beautifully.

Ingredients For Low Carb Chicken And Mushroom Soup
Olive oil: Used for sautéing the chicken and vegetables, adding a rich flavor and healthy fats.
Chicken breast: Provides lean protein and becomes tender and flavorful when cooked in the soup.
Mushrooms: Adds an earthy, umami flavor and a meaty texture to the soup.
Onion: Adds sweetness and depth of flavor to the soup.
Garlic: Enhances the overall flavor with its aromatic and savory notes.
Chicken broth: Forms the base of the soup, providing a rich and savory liquid.
Heavy cream: Adds creaminess and a luxurious texture to the soup.

Pro Tip for Perfecting This Soup
When browning the chicken breast, make sure not to overcrowd the pot. Overcrowding can cause the chicken to steam rather than brown, which will affect the overall flavor of the soup. Cook the chicken in batches if necessary to ensure each piece gets a nice, golden-brown sear. This caramelization adds depth and richness to the final dish.

How to Store or Freeze This Soup
- Allow the soup to cool completely before storing. This helps prevent condensation, which can lead to a watery texture.
- Transfer the soup to airtight containers. For best results, use containers that are specifically designed for freezing to avoid freezer burn.
- Label each container with the date and contents. This will help you keep track of how long the soup has been stored.
- Store the soup in the refrigerator for up to 4 days. Make sure the temperature is set to 40°F (4°C) or below.
- For longer storage, place the soup in the freezer. It can be frozen for up to 3 months without losing its flavor and texture.
- When ready to use, thaw the soup in the refrigerator overnight. This slow thawing process helps maintain the quality of the soup.
- Reheat the soup on the stovetop over medium heat, stirring occasionally to ensure even heating. Avoid boiling, as this can cause the cream to separate.
- If reheating in the microwave, use a microwave-safe container and heat in short intervals, stirring in between to ensure even heating.
- Adjust seasoning if necessary after reheating, as flavors can sometimes mellow during storage.
How to Reheat Leftovers
On the stovetop: Pour the leftover soup into a pot. Heat over medium-low, stirring occasionally, until the soup is warmed through. This method helps maintain the creaminess and texture of the heavy cream.
In the microwave: Transfer the soup to a microwave-safe bowl. Cover with a microwave-safe lid or a microwave-safe plate to prevent splatters. Heat on high for 2-3 minutes, stirring halfway through to ensure even heating. Adjust the time as needed depending on your microwave's power.
In the oven: Preheat your oven to 350°F (175°C). Pour the soup into an oven-safe dish and cover with aluminum foil. Heat for about 20-25 minutes, or until the soup is hot throughout. This method is great if you're reheating a large batch.
In a slow cooker: Pour the leftover soup into the slow cooker. Set it to low and heat for 1-2 hours, stirring occasionally. This method is perfect for reheating while you go about your day.
Using a double boiler: Fill the bottom pot of a double boiler with water and bring it to a simmer. Place the soup in the top pot and heat, stirring occasionally, until warmed through. This gentle method helps prevent the cream from curdling.
