It’s cozy, comforting, and ready in about 30 minutes, the perfect weeknight dinner that’s keto, gluten-free, and irresistibly satisfying.

Ingredients

Scale

  • 1 lb (450 g) Italian sausage (mild or spicy)

  • 4 slices bacon, chopped

  • 1 tbsp olive oil

  • 1 small onion, diced

  • 4 cloves garlic, minced

  • 4 cups (1 L) chicken broth, low-sodium

  • 1 small head cauliflower, cut into florets

  • 2 cups kale, chopped (stems removed)

  • 1 cup heavy cream

  • ½ cup grated Parmesan cheese

  • Salt and pepper, to taste

  • Optional garnish: chopped parsley, extra Parmesan, red pepper flakes

Instructions

  • Sauté bacon:
    Set Instant Pot to Sauté (Normal). Add chopped bacon and cook 3–4 minutes until crispy. Remove and set aside, leaving about 1 tbsp fat in the pot.

  • Brown sausage:
    Add Italian sausage and cook 4–5 minutes, breaking into crumbles until browned.

  • Add onion and garlic:
    Stir in diced onion and cook 2 minutes until softened. Add garlic and cook 30 seconds until fragrant.

  • Deglaze:
    Pour in ½ cup broth and scrape up any brown bits from the bottom.

  • Pressure cook:
    Add remaining broth and cauliflower florets. Lock lid, set valve to Sealing, and cook on High Pressure for 5 minutes. Quick release when done.

  • Add cream and kale:
    Switch to Sauté (Low). Stir in kale, heavy cream, and Parmesan. Simmer 3–5 minutes until kale is wilted and soup thickens slightly.

  • Season and serve:
    Taste and adjust with salt and pepper. Stir bacon back in. Serve hot, topped with extra Parmesan and parsley.

Notes

  • Dairy-Free: Substitute coconut cream and nutritional yeast for heavy cream and Parmesan.

  • Vegetable Swaps: Try spinach or broccoli instead of kale; both work beautifully.

  • Storage: Keeps 4 days refrigerated, 3 months frozen. Add cream after reheating if freezing.

  • Thickness Tip: For a creamier texture, mash a few cauliflower florets into the soup before serving.

  • Slow Cooker Option: Cook on Low 6 hrs or High 3 hrs, adding cream and kale at the end.
