Keto Gluten-Free Mushroom Soup with Turkey Recipe

This Keto Gluten-Free Mushroom Soup with Turkey has become an absolute staple in our household, especially as the cooler months roll in.

Yields: 6-8 servings
Prep time: 25 minutes
Cook time: 45-50 minutes

Ingredients:

• 2 tablespoons unsalted butter
• 1 tablespoon olive oil
• 1 large yellow onion, finely chopped (about 1.5 cups)
• 2 cloves garlic, minced
• 1 pound mixed mushrooms (e.g., cremini, shiitake, oyster), sliced or roughly chopped
• 8 ounces button mushrooms, finely chopped (for texture)
• 1 teaspoon dried thyme (or 1 tablespoon fresh thyme leaves)
• 1/2 teaspoon dried rosemary, crushed (or 1 teaspoon fresh, minced)
• Salt and freshly ground black pepper to taste
• 4 cups chicken or turkey broth (ensure gluten-free)
• 1.5 – 2 cups cooked turkey, shredded or diced (leftover Thanksgiving turkey works perfectly!)
• 1 cup heavy cream
• 4 ounces cream cheese, softened and cut into cubes
• 1 teaspoon xanthan gum (optional, for extra thickness if desired)
• 2 tablespoons fresh parsley, chopped (for garnish)
• 1 tablespoon fresh chives, chopped (for garnish, optional)
• A squeeze of fresh lemon juice (optional, to brighten flavors)

Instructions

Follow these steps carefully to achieve a perfectly creamy and flavorful Keto Gluten-Free Mushroom Soup with Turkey.

1. Sauté Aromatics and Mushrooms:
   • In a large Dutch oven or heavy-bottomed pot, melt the butter with olive oil over medium heat.
   • Add the chopped onion and cook until softened and translucent, about 5-7 minutes, stirring occasionally.
   • Add the minced garlic, dried thyme, and dried rosemary. Cook for another 1-2 minutes until fragrant, being careful not to burn the garlic.
   • Increase the heat slightly to medium-high. Add all the mushrooms (both the mixed variety and the finely chopped button mushrooms). Cook, stirring occasionally, until the mushrooms release their liquid and then begin to brown, about 10-15 minutes. This browning step is crucial for developing a deep, umami flavor. Don’t overcrowd the pan; if necessary, brown the mushrooms in batches. Season generously with salt and pepper.
2. Deglaze and Build the Broth:
   • Pour in about 1/2 cup of the chicken or turkey broth and scrape up any browned bits from the bottom of the pot with a wooden spoon. This process, called deglazing, adds immense flavor.
   • Add the remaining broth to the pot. Bring the mixture to a gentle simmer.
3. Simmer and Blend (Optional):
   • Reduce the heat to low, cover the pot, and let the soup simmer for 15-20 minutes to allow the flavors to meld together.
   • If you prefer a smoother soup, you can now partially blend it. Use an immersion blender directly in the pot to blend about one-third to one-half of the soup, leaving some chunky bits for texture. Alternatively, carefully transfer a portion of the soup to a regular blender (ensure the lid is vented and cover with a towel), blend until smooth, and then return it to the pot. Be cautious when blending hot liquids. If you prefer a fully chunky soup, skip this step.
4. Add Turkey and Creaminess:
   • Stir in the cooked, shredded, or diced turkey.
   • In a small bowl, whisk together the heavy cream and the xanthan gum (if using) until smooth. This prevents the xanthan gum from clumping when added to the hot soup.
   • Gradually stir the cream mixture into the simmering soup.
   • Add the softened cream cheese cubes to the soup, stirring gently until they melt completely and the soup becomes creamy and slightly thickened.
5. Final Seasoning and Serve:
   • Continue to simmer for another 5-10 minutes, allowing the soup to thicken slightly more and the flavors to fully incorporate. Do not let it come to a rolling boil after adding the cream.
   • Taste the soup and adjust seasoning with salt and pepper as needed. A small squeeze of fresh lemon juice at this stage can brighten the overall flavor profile wonderfully.
   • Ladle the hot Keto Gluten-Free Mushroom Soup with Turkey into bowls. Garnish with fresh chopped parsley and chives, if desired.

Additional Tips

To make your Keto Gluten-Free Mushroom Soup with Turkey even more spectacular, consider these five tips:

1. Mushroom Magic – Maximize Flavor:
   Don’t be afraid to use a variety of mushrooms. Cremini mushrooms (baby bellas) provide a good, earthy base. Shiitake mushrooms add a deeper, almost smoky umami flavor. Oyster mushrooms contribute a delicate, slightly savory note. The key to great mushroom flavor is to brown them properly. Don’t overcrowd the pan, as this will cause them to steam rather than sear. Cook them in batches if necessary, allowing them to release their moisture and then caramelize. This step is crucial for developing the rich, savory backbone of the soup.
2. Building a Flavor Base:
   Take your time when sautéing the onions. Allowing them to become soft and translucent, or even lightly caramelized, builds a sweet and savory foundation that significantly enhances the overall taste. Similarly, toasting the dried herbs (thyme, rosemary) with the garlic for a minute before adding liquids helps to wake up their aromatic compounds, making them more potent and flavorful in the final soup.
3. Creaminess Control & Alternatives:
   While heavy cream and cream cheese are excellent for a keto-friendly creamy texture, you can adjust the amounts to your preference. For an even richer soup, increase the cream cheese slightly. If you find the soup too thick after adding xanthan gum (which is optional), you can thin it with a little more broth or water. For those who might be sensitive to dairy or looking for a different profile, full-fat canned coconut milk (the thick part) can be used as an alternative to heavy cream, though it will impart a subtle coconut flavor. Ensure your cream cheese is well-softened to prevent lumps.
4. Turkey Talk – Best Practices:
   This soup is a fantastic way to use leftover roasted turkey, especially after holidays like Thanksgiving or Christmas. Both white and dark meat work well. If you don’t have leftovers, you can quickly cook some turkey tenderloins or ground turkey. If using ground turkey, brown it separately, drain any excess fat, and then add it to the soup. Shredding the turkey rather than dicing it can provide a more pleasant texture that integrates well into the creamy soup.
5. Storage and Reheating Savvy:
   This soup stores wonderfully and often tastes even better the next day as the flavors meld. Cool the soup completely before transferring it to an airtight container. It can be refrigerated for up to 3-4 days. When reheating, do so gently over low to medium heat on the stovetop, stirring occasionally to prevent scorching, especially due to the cream content. Avoid boiling. If the soup has thickened too much upon refrigeration, you can add a splash of broth or water to reach your desired consistency. Freezing is also an option, though cream-based soups can sometimes experience a slight change in texture upon thawing (they might separate a bit). If freezing, thaw in the refrigerator overnight and whisk well while reheating gently. Adding a touch more fresh cream when reheating can help restore its texture.

FAQ Section

Here are answers to some frequently asked questions about this Keto Gluten-Free Mushroom Soup with Turkey:

Q1: Can I make this soup vegetarian or vegan?
A1: Yes, with modifications. For a vegetarian version, simply omit the turkey and use a good quality vegetable broth. You might want to add more mushrooms or other hearty vegetables like diced celery root or cauliflower florets (cooked until tender) to maintain substance. For a vegan version, replace the butter with vegan butter or more olive oil, use vegetable broth, omit the turkey, and substitute the heavy cream and cream cheese with dairy-free alternatives. Full-fat canned coconut milk (use the solid cream part) can replace heavy cream, and there are several good brands of vegan cream cheese available. The flavor profile will change, but it can still be delicious.

Q2: What other types of mushrooms can I use?
A2: You have a lot of flexibility! While cremini, shiitake, and oyster mushrooms are recommended for their flavor profiles, feel free to experiment. Portobello mushrooms (remove the dark gills to prevent the soup from becoming too dark), chanterelles (if you can find them and they fit your budget), or even simple white button mushrooms will work. A mix is always best for complexity. Dried mushrooms like porcini can also be rehydrated (save the soaking liquid to add to the broth!) and added for an intense umami boost.

Q3: My soup isn’t as thick as I’d like. How can I thicken it further?
A3: There are several keto-friendly ways to thicken it. First, ensure your cream cheese was fully incorporated, as it contributes to thickness. The xanthan gum is specifically for this purpose; you can add a tiny bit more (make a slurry with a little cold water or oil first to prevent clumping) if needed, but use it sparingly as too much can result in a slimy texture. Another method is to simmer the soup uncovered for a longer period to allow more liquid to evaporate and reduce naturally. You can also blend a larger portion of the soup, as blended vegetables naturally thicken liquids.

Q4: Can I prepare any parts of this soup ahead of time?
A4: Absolutely! To save time, you can chop the onions and mushrooms a day in advance and store them in airtight containers in the refrigerator. If you’re cooking turkey specifically for this soup, that can also be done ahead of time and stored shredded or diced. Having these components prepped will make the actual soup-making process much quicker on the day you plan to serve it.

Q5: Is this soup suitable for meal prepping for the week?
A5: Yes, this soup is excellent for meal prepping. As mentioned in the tips, it stores well in the refrigerator for 3-4 days and its flavors often improve over time. Portion it out into individual containers for easy grab-and-go lunches or quick dinners throughout the week. Reheat gently on the stovetop or in the microwave (if using microwave, cover to prevent splatters and stir partway through). It’s a satisfying and nutritious option that will keep you on track with your keto and gluten-free goals.
