• 16 ounces (450 g) mushrooms, sliced
• 1 medium onion, finely chopped
• 3 cloves garlic, minced
• 4 cups (960 ml) chicken broth

• 1 tablespoon olive oil
• 1 teaspoon dried thyme
• ½ teaspoon dried rosemary

How to Make Creamy Slow Cooker Chicken and Mushroom Soup

Step 1: Prepare the Vegetables

Clean the mushrooms with a damp paper towel and slice them evenly. Chop the onion and mince the garlic.

If you have a few extra minutes, sauté the mushrooms and onion in butter and olive oil in a skillet until the mushrooms begin to brown. Add the garlic during the final minute.

This step is optional, but browning the mushrooms adds a deeper, richer flavor to the finished soup. If you’re short on time, you can add the ingredients directly to the slow cooker.

Step 2: Add the Ingredients to the Slow Cooker

Place the chicken breasts or thighs in the bottom of the slow cooker. Add the sliced mushrooms, onion, garlic, thyme, rosemary, black pepper, and chicken broth.

Stir gently to distribute the seasonings. The broth should surround the chicken and vegetables, allowing everything to cook evenly.

Hold off on adding the cream for now. Adding it near the end helps preserve its smooth texture.

Step 3: Let Everything Cook Slowly

Cover the slow cooker and cook on LOW for approximately 4–6 hours or on HIGH for 2–3 hours.

Cooking times vary depending on the thickness of the chicken and your appliance. Check the chicken with a food thermometer and make sure it reaches an internal temperature of 165°F (74°C).

Once the chicken is cooked and tender, remove it from the slow cooker and place it on a plate.

Step 4: Shred the Chicken

Using two forks, shred the chicken into bite-sized pieces. It should pull apart easily when properly cooked.

Return the shredded chicken to the slow cooker and stir it into the mushroom broth.

At this stage, the soup should already smell wonderfully savory, with the garlic, herbs, and mushrooms blending into the chicken broth.

Step 5: Make the Soup Creamy

Pour the heavy cream into the slow cooker and stir gently.

For a thicker soup, whisk the optional flour with a little cold water until smooth, then stir it into the soup. Alternatively, mix the flour with softened butter to make a paste before incorporating it into the hot broth.

Let the soup cook on HIGH for another 10–20 minutes, stirring occasionally, until it reaches your preferred consistency. Avoid allowing the soup to boil vigorously after adding the cream.

If you’d like an extra savory finish, stir in the grated Parmesan cheese.

Step 6: Add the Finishing Touches

Taste the soup and adjust the salt and black pepper as needed. A small squeeze of lemon juice can brighten the creamy broth and balance its richness.

Sprinkle freshly chopped parsley over the top just before serving.

Ladle the soup into bowls and serve while warm. Every bowl should have a generous helping of tender chicken, mushrooms, and creamy broth.

My Best Tips for Perfect Chicken and Mushroom Soup

Brown the mushrooms first. This optional step gives the mushrooms a deeper, more savory flavor and adds extra character to the broth.

Use chicken thighs for extra richness. Chicken breasts are lean and work beautifully, while thighs tend to remain moist and have a slightly richer flavor.

Add cream near the end. This helps keep the soup smooth and reduces the chance of the cream separating during prolonged cooking.

Slice the mushrooms evenly. Similar-sized slices cook at a more consistent rate and make the soup easier to eat.

Season gradually. Chicken broth and Parmesan can contain plenty of sodium, so taste the soup before adding extra salt.

Adjust the consistency to your liking. For a lighter soup, add a little extra broth. For a thicker, more luxurious texture, use the optional thickener or add a little more cream.

Delicious Variations to Try

Garlic Parmesan Chicken Mushroom Soup

Add extra garlic and a little more Parmesan cheese for a deeper, savory flavor. Finish with fresh parsley for a lovely contrast.

Chicken and Spinach Soup

Stir in a few handfuls of fresh spinach during the final 5 minutes of cooking. It wilts quickly and adds color and extra nutrients.

Low-Carb Creamy Chicken Soup

Skip the flour and use a little less onion if desired. You can also add extra mushrooms or chopped spinach for a satisfying, lower-carbohydrate meal.

Dairy-Free Chicken and Mushroom Soup

Replace the butter with olive oil and use an unsweetened, unflavored dairy-free cream alternative. Choose a product suitable for savory cooking, as some alternatives can change the flavor and thickness.

Extra-Mushroom Soup

Use a mixture of cremini, button, and shiitake mushrooms for a more complex, earthy flavor.

What to Serve With Creamy Chicken and Mushroom Soup

This soup is hearty on its own, but a few simple sides can turn it into a lovely meal.

• Crusty bread: Perfect for dipping into the creamy broth.
• Garlic bread: Adds a delicious garlic flavor and a little crunch.
• Fresh green salad: A light salad with cucumber, tomatoes, and lemon dressing balances the richness of the soup.
• Roasted vegetables: Carrots, broccoli, or green beans make a colorful side.
• Buttered toast: A simple option for a quick and comforting lunch.

For a cozy dinner, serve a generous bowl of soup with warm crusty bread and a small side salad. It’s an easy combination that feels complete without requiring much extra cooking.

Storage and Reheating

Refrigerator: Allow the soup to cool slightly and refrigerate it in an airtight container within two hours of cooking. Enjoy within 3–4 days.

Freezer: Cream-based soups can change texture when frozen, so freezing is best done before adding the cream. Freeze the chicken and mushroom broth in airtight containers for up to 2–3 months for best quality. Thaw in the refrigerator, reheat thoroughly, and add fresh cream at the end.

Reheating: Warm the soup gently on the stovetop over medium-low heat, stirring occasionally. Add a splash of broth if it has thickened too much. Avoid vigorous boiling after the cream has been added.

Nutritional Information

The following values are estimates per serving, assuming the recipe makes six servings using chicken breasts, mushrooms, chicken broth, heavy cream, butter, olive oil, and no optional flour or Parmesan.

Nutritional values are approximate and vary with the type of chicken, cream, broth, and portion size. Adding flour, Parmesan, or other ingredients will change the totals.

Frequently Asked Questions

Can I use frozen chicken in the slow cooker?

It’s safest to thaw chicken completely in the refrigerator before adding it to a slow cooker. Frozen chicken can remain at an unsafe temperature for too long while the appliance heats.

Can I use milk instead of heavy cream?

Yes, but the soup will be thinner and less rich. Whole milk is a better choice than skim milk. For a thicker texture, use a suitable thickener and add the milk near the end.

How do I keep the cream from curdling?

Add the cream toward the end of cooking and avoid boiling the soup vigorously afterward. Stir it in gradually for a smooth, creamy finish.

Can I make this soup on the stovetop?

Absolutely. Sauté the mushrooms, onion, and garlic in a large pot. Add the chicken, herbs, and broth, then simmer gently until the chicken reaches 165°F (74°C). Remove and shred the chicken, return it to the pot, and stir in the cream. Simmer gently until heated through.

Why is my soup too thin?

You can simmer it uncovered in a saucepan to reduce some of the liquid, or stir in a flour or cornstarch slurry. Allow a little time for the thickener to work before adding more.

Can I make this soup ahead of time?

Yes. The chicken, mushrooms, and broth can be prepared ahead and refrigerated. For the best creamy texture, add the cream when reheating the soup.
