Wholesome Ingredients for This Creamy Italian Sausage Soup

Each ingredient in this keto Italian sausage soup recipe was chosen with both flavor and nutrition in mind. Here’s why these standouts are key:

Italian sausage: This is the star of the soup, offering bold, savory flavor and plenty of protein. Choose hot sausage for a spicy kick or mild if you prefer it subtle. Need a substitution? Try ground turkey sausage and ramp up the seasoning yourself.
Spinach: Fresh baby spinach wilts beautifully into the hot broth, delivering a subtle flavor and a hefty dose of iron and antioxidants. Swap for kale if desired for an earthier taste.
Zucchini: This versatile veggie keeps the dish light while offering added texture and fiber. Select firm zucchinis with smooth skin for the best results. Can’t find zucchini? Yellow squash works beautifully too.
Cream cheese: This is the secret to the luxurious, creamy broth while keeping the soup keto-friendly. Be sure to use full-fat cream cheese, or substitute Neufchâtel for a lighter option.

Ingredients for Creamy Italian Sausage Soup

2 tbsp butter

2 tsp minced garlic
1 lb ground Italian sausage (try hot if you like it spicy!)
6 cups chicken bone broth
1 14oz can diced fire-roasted tomatoes

How to Make Creamy Italian Sausage Soup

Melt butter in a large soup pot over medium-high heat.
Add chopped onions, garlic, and sausage to the pot. Cook, stirring and breaking the meat apart with a spoon, until the onions are soft, translucent, and the sausage is browned.
Pour in the chicken bone broth and add the fire-roasted tomatoes. Stir in the cream cheese until fully melted and the broth is smooth.
Add the zucchini, basil, oregano, and black pepper. Bring the mixture to a boil, then reduce heat to a simmer. Allow it to cook for 15-20 minutes, or until the zucchini is tender.
Add the spinach and let it wilt into the soup, about 3 minutes.
Serve hot, garnished with fresh shredded Parmesan cheese if desired. Enjoy!

Nutritionist-Approved Tips for Creamy Italian Sausage Soup

Use quality Parmesan: Shredding your own parmesan at home not only boosts the flavor but also avoids unnecessary additives found in pre-shredded varieties.
Opt for fresh spinach: While frozen spinach can work in a pinch, fresh baby spinach has the best texture and taste for this soup.
Spicy or mild: Use hot sausage if you love a kick of heat, or balance it with a light drizzle of olive oil for extra richness.
Make it ahead: This soup stores well! Refrigerate in an airtight container for up to 3 days and reheat gently on the stove.
Thinning it out: If the soup thickens too much while cooling, just add a splash of broth or water when reheating.
