3. Secure the lid on the Instant Pot, ensuring the steam release valve is set to the ‘Sealing’ position.

6. Stir the soup one last time, serve warm, and enjoy!

Pro Tips

• For a deeper flavor profile, use the ‘Sauté’ function to brown the sausage and soften the onions and mushrooms before adding the other and pressure cooking.
• If you prefer a thicker, chowder-like consistency, create a slurry with 1 teaspoon of xanthan gum and 1 tablespoon of olive oil and whisk it into the soup after pressure cooking.
• Stir in a few large handfuls of fresh spinach or kale at the end, after pressure cooking. The residual heat will wilt the greens perfectly.
• For a spicy kick, use hot ground sausage or add a pinch of red pepper flakes with the other seasonings.
• Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stovetop, avoiding boiling to prevent the cream from separating.

FAQ

Q: Is this sausage and mushroom soup keto-friendly
A: Yes, this Creamy Instant Pot Sausage and Mushroom Soup is perfectly keto-friendly. With only 3g of net carbs per serving, it’s a delicious and satisfying low-carb meal packed with healthy fats and protein.

Q: What can I use instead of daikon radish
A: If you don’t have daikon radish, you can substitute it with other low-carb vegetables like chopped turnips, celery, or cauliflower florets to maintain the soup’s hearty texture without adding significant carbs.

Q: Can I make this soup on the stovetop instead of an Instant Pot
A: Absolutely. To make this on the stovetop, sauté the sausage, onions, and mushrooms in a large pot. Add the broth and seasonings and simmer for 20 minutes. Reduce the heat and stir in the heavy cream and Parmesan cheese at the end, heating gently without boiling.

Q: How can I make this soup thicker
A: For a thicker, chowder-like consistency, the pro tips suggest creating a slurry with 1 teaspoon of xanthan gum and 1 tablespoon of olive oil. Whisk this mixture into the soup after it has finished pressure cooking until it reaches your desired thickness.
