Essential Ingredients For The Perfect Low Carb Chicken Mushroom Soup
Crafting this delicious soup begins with selecting fresh, high-quality ingredients. Each component plays a vital role in building the layered flavors and rich texture that define this dish, contributing to its comforting and healthy profile. Here’s what you’ll need to create this culinary delight:
- Unsalted Butter: The foundational fat for sautéing, adding a luxurious, creamy base and rich flavor. Butter helps caramelize the vegetables beautifully.
- Sweet Onion: Provides a foundational sweetness and aromatic depth that mellows beautifully during cooking, enhancing the overall savory profile.
- Chopped Celery: A classic aromatic vegetable that offers a subtle crunch and a delicate, earthy flavor, forming part of the essential mirepoix base.
- Garlic Cloves: Indispensable for its pungent, savory notes that infuse the entire soup, elevating all other flavors. Freshly minced garlic delivers the most vibrant taste.
- Sliced Mushrooms: The undisputed star of the show! We highly recommend using a mix of varieties like cremini (baby bellas), shiitake, and even oyster mushrooms for the most complex, earthy, and umami-rich notes. Different mushrooms bring unique textures and depths of flavor.
- Fresh Chopped Rosemary: Infuses the soup with its distinctive, piney, and slightly peppery aroma and flavor, which pairs exceptionally well with both chicken and mushrooms.
- Dried Thyme: A classic companion to chicken and mushrooms, offering an earthy, slightly minty undertone that complements the rosemary and garlic.
- Dry Sherry: Crucial for deglazing the pot, adding a layer of sophisticated, nutty sweetness and complexity that truly enhances the umami of the mushrooms and caramelized bits. It’s a secret ingredient for a gourmet touch.
- Boneless Chicken Breast: Lean and tender protein that becomes incredibly succulent when cooked directly in the flavorful broth, absorbing all the wonderful spices and aromatics.
- Chicken Broth: The essential liquid base, providing a savory depth that ties all the ingredients together. Opt for a high-quality, low-sodium chicken broth or bone broth for added nutritional benefits.
- Heavy Cream: Essential for achieving that luxurious, velvety creamy texture and rich mouthfeel, making the soup incredibly satisfying. It’s particularly important for boosting the fat content in a ketogenic diet.
- Cornstarch (or Arrowroot for Ketogenic): A natural thickening agent used to give the soup its perfect, slightly viscous consistency. For a strictly ketogenic version, arrowroot powder is an excellent carb-friendly alternative.
- Chopped Fresh Parsley: Used as a vibrant garnish, offering a burst of fresh, herbaceous flavor and a beautiful contrasting color that brightens the dish.
- Salt and Pepper: To taste, these fundamental seasonings are used throughout the cooking process to enhance, balance, and fine-tune all the exquisite flavors of the soup.

Expert Tips for a Perfectly Creamy Low Carb Chicken Mushroom Soup
- The Art of Poaching Chicken for Flavor & Tenderness: A true secret to achieving genuinely flavorful and tender chicken in soup is to poach whole chicken breasts directly in the broth. This gentle cooking method not only enriches the chicken broth with deeper, more savory flavors but also meticulously protects the chicken from overcooking, ensuring it remains incredibly juicy and succulent. Once perfectly cooked, simply remove the breasts, chop them into your desired bite-sized pieces, and return them to the simmering soup. This technique guarantees juicy, tender chicken every single time.
- Effortless Chopping for Ideal Texture: You’ll find that cooked chicken is significantly easier to cut into uniform, aesthetically pleasing chunks compared to raw chicken. After poaching, use tongs to carefully remove the breasts from the hot liquid, allow them to cool slightly (just enough to handle comfortably), then effortlessly chop them before reintroducing them into your luxurious mushroom and chicken soup. This maintains the chicken’s integrity and prevents shredding.
- Achieving Ketogenic Balance with Cream: The judicious addition of heavy cream is not merely for its delightful flavor and rich texture; it’s a vital component for precisely balancing the macronutrients of this Low Carb Creamy Chicken Mushroom Soup, making it perfectly suited and compliant for a ketogenic diet. Its significant fat content helps achieve the desired fat-to-protein ratio essential for ketosis.
- Delicious Dairy-Free Option: While this recipe is undeniably incredible with dairy, we understand dietary preferences. You can certainly enjoy a wonderful dairy-free version if preferred. Omitting the heavy cream will naturally result in a thinner broth, and the soup will technically no longer be considered “ketogenic” due to the reduced fat content. However, it will still be delightfully low carb, exceptionally high in protein, and wonderfully flavorful, making it tantalizing to the tastebuds for those with specific dietary restrictions or preferences.
- Embrace Mushroom Variety: Don’t limit your culinary adventure to just one type of mushroom! Experiment with various fungi like cremini, shiitake, oyster, or even a blend of wild mushrooms for an even richer, more complex, and multi-dimensional umami profile. Each variety brings its own unique texture and subtle flavor notes.
- The Unrivaled Impact of Fresh Herbs: While dried herbs offer convenience, fresh rosemary and parsley truly elevate the aroma and vibrancy of this soup to a gourmet level. Their bright, pungent notes make a significant difference. If you must use dried herbs, remember that they are more potent and concentrated, so typically use about half the amount specified for fresh herbs.
Serving Suggestions and Complementary Side Dishes
This healthy mushroom chicken soup is incredibly satisfying and wholesome on its own, easily serving as a complete meal.

- Traditional (Non-Low Carb) Options: For those not strictly adhering to low-carb or keto, these classic pairings offer added comfort and indulgence.
- Fluffy Southern Cat Head Biscuits: For a truly comforting, soulful, and undeniably indulgent pairing, these light and airy biscuits are unbeatable.
- Homemade Yeast Rolls: Soft, warm, and slightly sweet, these rolls are ideal for soaking up the rich and savory broth.
- Classic Garlic Bread: A timeless and incredibly popular choice that adds a wonderful garlicky crunch and complements the soup’s robust flavors perfectly.
- Gourmet Grilled Cheese Sandwich: The ultimate comfort food duo; a crispy, cheesy sandwich dipped into creamy soup is pure bliss.
- Crusty artisanal bread, such as a baguette or sourdough, is excellent for dipping and savoring the broth.

Frequently Asked Questions About Low Carb Creamy Chicken Mushroom Soup
What does “deglaze” mean, and why is it important for this soup?
Deglazing is a crucial and flavor-enhancing cooking technique that involves pouring a liquid, in this case, dry sherry, into a hot pan and allowing it to simmer vigorously. This action helps to loosen and lift any highly flavorful, browned, crusty particles (often called “fond”) that have stuck to the bottom of the pan during initial sautéing. Gently scraping the pan with a wooden spoon aids this process significantly. Deglazing not only prevents these flavorful bits from burning and becoming bitter, but more importantly, it incorporates all those intensely caramelized flavors back into the soup, profoundly intensifying its overall depth, richness, and umami profile. It’s a simple step that yields immense flavor rewards.
Can I make this chicken mushroom soup in a crockpot or slow cooker?
Absolutely! This delectable recipe adapts beautifully to a slow cooker, making it perfect for busy days. For the absolute best results and maximum flavor development, it is highly recommended to sauté the initial vegetables (onions, celery, garlic, mushrooms) on the stovetop in a separate pan first. This crucial sautéing step is vital for developing those deep, rich, umami flavors that truly make the soup shine. After sautéing, transfer them to your slow cooker pot with the chicken and broth. Cook on low for 4-6 hours, or until the chicken is fork-tender. About 30-60 minutes before you plan to serve, stir in the cream mixture (heavy cream whisked with cornstarch or arrowroot) and allow it to simmer gently in the slow cooker to thicken. The result will be a wonderfully creamy, homemade chicken mushroom soup with minimal active effort!
What can I use as a substitute if I don’t have dry sherry?
Dry sherry plays a surprisingly significant role in enhancing the flavor profile of this soup, offering a complex, nutty, and slightly sweet note that perfectly complements the earthy mushrooms and savory chicken. It truly adds an invaluable layer of sophistication and depth. However, if you prefer not to use alcohol or simply don’t have it on hand, you can certainly substitute it with an equal amount of additional high-quality chicken broth. While the soup will still be delicious and comforting, you might notice a slight difference in the overall aromatic complexity and depth of flavor. Small bottles of cooking sherry are often readily available in the international or condiments aisle of most grocery stores if you decide to try it in the future.
Is this chicken mushroom soup suitable for freezing?
Yes, this creamy chicken mushroom soup freezes surprisingly well and is an excellent option for convenient meal prepping! It can be stored in an airtight, freezer-safe container for an extended period, typically up to 6 months, without significant loss of quality. To ensure the best results when reheating, it’s highly recommended to allow the soup to thaw gradually in the refrigerator overnight or at room temperature for a few hours. Then, gently reheat it on the stovetop over medium-low heat, stirring frequently to prevent the cream from separating and maintaining its smooth, luxurious consistency once warmed through. Avoid vigorous boiling during reheating.
How long does this soup keep fresh in the refrigerator?
When stored properly in an airtight container, this Low Carb Creamy Chicken Mushroom Soup will maintain its peak freshness, flavor, and quality in the refrigerator for a generous period of 4 to 6 days. In fact, many find that the soup’s flavors meld and deepen even further after a day or two, making it an excellent candidate for making ahead for lunches or easy dinners throughout the week.
Can I make this soup vegetarian or vegan?
While this recipe prominently features chicken, you can absolutely adapt it to be vegetarian! Simply replace the boneless chicken breast with an equivalent amount of extra mushrooms (consider hearty options like sliced portobello or more oyster mushrooms for a ‘meaty’ texture) and ensure you use a rich vegetable broth instead of chicken broth. For a completely vegan version, in addition to the above, replace the butter with olive oil or a plant-based butter alternative, and substitute the heavy cream with a full-fat coconut milk or another dairy-free cream alternative. You might also consider adding some sautéed chickpeas or white beans for added protein and substance, though this would slightly increase the overall carb count.

Ingredients
(Units are US Customary)
- 2 tablespoons unsalted butter
- 1 large sweet onion, peeled and chopped
- 1 cup chopped celery
- 5-6 cloves garlic, peeled and minced
- 18 ounces sliced mushrooms (mixed varieties recommended)
- 1 teaspoon fresh chopped rosemary
- 1 teaspoon dried thyme
- 1/3 cup dry sherry
- 1 pound boneless chicken breast
- 8 cups chicken broth
- 2/3 cup heavy cream
- 1 tablespoon cornstarch (or arrowroot for ketogenic)
- 1/4 cup chopped fresh parsley
- Salt and pepper, to taste
Instructions
- Add the butter to a large 6-8 quart soup pot and set over medium heat. Once melted, add the chopped onions, celery, and minced garlic. Sauté for 2-3 minutes until fragrant and slightly softened.
- Stir in the sliced mushrooms, fresh rosemary, and dried thyme. Continue to sauté, stirring occasionally, until the mushrooms have softened, released their moisture, and significantly cooked down, which typically takes about 5-7 minutes.
- Deglaze the pot with the dry sherry, scraping the bottom of the pot vigorously with a wooden spoon to loosen any browned bits. Allow the sherry to simmer for about 1 minute until slightly reduced.
- Add the whole boneless chicken breasts, chicken broth, 1 teaspoon salt, and 1/4 teaspoon black pepper to the pot. Bring the mixture to a gentle boil, then immediately reduce the heat to a low simmer. Cover and cook for 15 minutes, or until the chicken breasts are thoroughly cooked through and reach an internal temperature of 165°F (74°C).
- Once the chicken is fully cooked, carefully remove the breasts from the soup using tongs. Transfer them to a cutting board and allow them to cool slightly. Once cool enough to handle, chop the cooked chicken into bite-sized pieces. Set aside.
- While the soup is simmering, in a small separate bowl, whisk the cornstarch (or arrowroot) into the heavy cream until no clumps remain, creating a smooth, lump-free slurry.
- Gradually whisk the heavy cream mixture into the simmering soup pot. Continue to cook gently, stirring occasionally, for another 5-10 minutes, allowing the soup to thicken to your desired creamy consistency.
- Return the chopped chicken pieces to the soup. Stir in the fresh chopped parsley.
- Taste the soup and adjust seasoning with additional salt and pepper as needed to achieve your perfect flavor balance. Serve hot and enjoy immediately!
Notes
This soup is wonderfully rich with dairy. However, if you prefer a dairy-free version, simply omit the heavy cream. The broth will be thinner but still incredibly flavorful and delightful! For a strictly ketogenic version, ensure you use arrowroot powder instead of cornstarch if you choose to thicken the soup, as arrowroot is generally lower in carbs.
