Ingredients You’ll Need

For the “Tortellini”

  • 8 oz mozzarella cheese (shredded)
  • 2 tbsp almond flour
  • 1 large egg yolk
  • ½ tsp Italian seasoning

For the Soup

  • 1 lb Italian sausage (ground or removed from casings)
  • 2 tbsp olive oil
  • 4 cups chicken broth (use low-sodium if you prefer)
  • 1 cup heavy cream
  • 1 small onion (diced)
  • 2 cloves garlic (minced)
  • 1 cup spinach (chopped, fresh or frozen)
  • ½ cup sun-dried tomatoes (chopped)
  • ½ tsp red pepper flakes (optional, for a little kick)
  • Salt and pepper to taste
  • Fresh basil or parsley (optional, for garnish)

How to Make Keto Sausage Tortellini Soup

Step 1: Make the Tortellini

  • Melt the cheese: Add the shredded mozzarella to a microwave-safe bowl and heat it in 20-second intervals until it’s fully melted. Stir to make it smooth.
  • Mix the dough: Stir in the almond flour, egg yolk, and Italian seasoning until the mixture forms a dough. It’ll be sticky, but that’s normal.
  • Shape the tortellini: Roll the dough into small circles (about 2 inches wide). Place a tiny pinch of mozzarella in the center of each circle, fold it over into a half-moon shape, and pinch the edges to seal. Then, fold the corners together to form the tortellini shape. Set them aside.

Pro tip: If the dough gets too stiff to work with, pop it back in the microwave for 10 seconds to soften it.

Step 2: Cook the Sausage

  • Heat the olive oil in a large soup pot over medium heat.
  • Add the sausage and cook it until it’s browned, breaking it into crumbles with a spatula.
  • Remove the sausage from the pot and set it aside. Leave the drippings in the pot for extra flavor.

Step 3: Sauté the Vegetables

  • In the same pot, toss in the diced onion and garlic. Cook until the onion is soft and translucent—about 3 minutes.
  • Stir in the sun-dried tomatoes and red pepper flakes (if using), letting the flavors combine for a minute.

Step 4: Build the Broth

  • Pour in the chicken broth and heavy cream. Stir everything together.
  • Add the cooked sausage back into the pot and bring the soup to a gentle simmer.

Step 5: Add the Spinach and Tortellini

  • Stir in the chopped spinach and let it wilt.
  • Gently drop in your keto tortellini and let them cook in the soup for about 3–5 minutes. They’ll firm up slightly as they heat.

Step 6: Taste and Finish

  • Give the soup a taste and adjust the seasoning with salt and pepper as needed.
  • Ladle the soup into bowls, garnish with fresh basil or parsley, and serve hot.

Recipe Tips & Tricks

  • Make it spicy: Add more red pepper flakes or use hot Italian sausage if you love a little heat.
  • Storage: Keep leftovers in an airtight container in the fridge for up to 3 days. Reheat gently on the stovetop to avoid overcooking the tortellini.
  • Freezer-friendly: The soup base (without tortellini) freezes beautifully. Just thaw it, reheat, and add freshly made tortellini before serving.
  • Substitutions: Not into spinach? Kale works just as well. You can also swap sun-dried tomatoes for diced fresh ones.

Why This Soup Works for Keto

The star of this recipe is the tortellini hack—turning cheese and almond flour into tender, cheesy bites that mimic the real deal. Plus, the heavy cream and sausage give you a hearty dose of fat, while the spinach and tomatoes keep things fresh and nutritious. It’s the perfect balance of indulgent and healthy, and it won’t knock you out of ketosis.

Perfect Pairings

This soup is a meal on its own, but if you want to make it feel extra fancy, try serving it with one of these keto-friendly sides:

  • Cheddar biscuits: Low-carb and perfect for soaking up the broth.
  • Garlic butter zucchini noodles: A lighter option if you’re really hungry.
  • Cauliflower rice: For a rice-soup combo that’s surprisingly filling.

Conclusion

Keto Sausage Tortellini Soup isn’t just a recipe; it’s proof that eating low-carb doesn’t mean giving up on comfort food. With creamy broth, flavorful sausage, and cheesy tortellini, it’s the kind of dish that makes you forget you’re even on a diet.

Whether you’re meal prepping for the week or just need something easy and delicious, this soup hits all the right notes. Bookmark it, pin it, or print it out—because you’re going to want this one in your regular rotation.

Frequently Asked Questions (FAQs)

Can I use store-bought keto pasta?

Absolutely! If making the tortellini feels like too much work, look for low-carb pasta options at your local grocery store. Just keep an eye on the carb count.

Is this soup gluten-free?

Yep! All the ingredients are naturally gluten-free, making it a safe choice for anyone avoiding gluten.

Can I make this dairy-free?
