Ingredients
Main Ingredients
- 1 tablespoon Olive oil or avocado oil
- 1 pound Italian sausage (mild or hot; remove casings if using links)
- 1 small Onion, diced
- 4 cloves Garlic, minced
- 4 cups Chicken broth (low sodium) Try homemade bone broth for richer flavor.
- 3 cups Cauliflower florets (bite size) Potato stand-in that keeps it keto.
- 1/3 cup Sun-dried tomatoes, chopped Packed in oil and patted dry.
- 1 teaspoon Italian seasoning
- 1/4 to 1/2 teaspoon Crushed red pepper flakes To taste.
- 3/4 cup Heavy cream Can substitute with coconut cream for dairy-free version.
- 1/2 cup Parmesan, finely grated Plus more for topping.
- 3 to 4 cups Baby spinach or chopped kale
- Salt and black pepper To taste.
- 3 slices Bacon, chopped and crisped (optional for topping)
Instructions
Sauté for Flavor
- Set the Instant Pot to Sauté and add oil. Brown the sausage, breaking it up as it cooks. Take your time here.
- Add onion and cook until soft, about 2 to 3 minutes. Stir in garlic for 30 seconds until fragrant.
Pressure Cook to Tender
- Pour in the broth, then scrape the bottom of the pot to get up all the browned bits.
- Stir in cauliflower, sun-dried tomatoes, Italian seasoning, and red pepper flakes.
- Lock the lid, set to High Pressure for 3 minutes, then quick release.
Finish Creamy and Bright
- Stir in heavy cream and Parmesan. Switch back to Sauté if you want a gentle simmer to thicken slightly.
- Add spinach or kale and stir until it wilts. Taste and season with salt and pepper.
- Ladle into bowls, top with extra Parmesan and bacon if used.
Notes
For best flavor, brown the sausage adequately, deglaze the pot fully, and use quality broth. Adjust heat with crushed red pepper flakes to taste. This soup can be made dairy-free using coconut cream instead of heavy cream, with a squeeze of lemon for brightness. Store in fridge for up to 4 days or freeze (without cream and greens) for longer durability.
