Cooking Instructions
-
Prepare The Ingredients
- Start by chopping the cauliflower into florets, which will mimic the texture of potatoes. Set them aside.
- Chop the kale or spinach into smaller pieces for easy cooking and a better texture.
- Dice the onion and mince the garlic. These aromatics will form the flavor base for your soup.
-
Cook The Sausage
- Heat a large pot over medium heat and add the olive oil.
- Add the ground Italian sausage to the pot and break it apart with a wooden spoon. Cook until browned and fully cooked through, about 5-7 minutes. Be sure to drain any excess fat if necessary.
-
Sauté The Aromatics
- Add the diced onion and minced garlic to the pot. Sauté for 2-3 minutes until the onions are translucent and the garlic is fragrant.
-
Simmer The Soup
- Add the cauliflower florets, chicken broth, red pepper flakes, salt, and black pepper to the pot. Stir to combine, then bring everything to a boil.
- Reduce the heat to a simmer and cook for about 10 minutes, or until the cauliflower is tender.
-
Add The Cream And Greens
- Once the cauliflower is soft, pour in the heavy cream and stir to combine. Add the chopped kale or spinach, and let it cook for an additional 5 minutes, until the greens are wilted and tender.
-
Final Adjustments
- Taste the soup and adjust seasoning if needed. You might want to add a pinch more salt, pepper, or red pepper flakes depending on your taste preference.
-
Serve And Garnish
- Ladle the soup into bowls, and if desired, sprinkle with grated parmesan cheese for an extra touch of flavor and richness. Serve hot!
Ingredient Insights
- Ground Italian Sausage: The sausage adds depth of flavor with its combination of spices, fennel, and garlic. It’s the perfect choice for this soup, but you can easily substitute with turkey sausage for a leaner version.
- Cauliflower: In this keto version of Zuppa Toscana, cauliflower is your potato stand-in. It mimics the texture of potatoes without the carbs, and when simmered in the broth, it takes on the flavors of the soup beautifully.
- Kale or Spinach: Both greens bring vitamins, minerals, and fiber to the dish. Kale is hearty and holds its shape well during cooking, while spinach wilts down more quickly and has a milder flavor.
- Heavy Cream: The creamy base gives this soup its signature richness. Heavy cream is the key to making it decadent, and a little goes a long way in giving you that luxurious mouthfeel.
Expert Tips
- Sausage Variations: If you’re looking for a different flavor profile, you can experiment with sweet sausage or even add a bit of ground pork for variation.
- Make it Spicy: For those who enjoy a spicy kick, increase the amount of red pepper flakes or even add a bit of crushed chili pepper for extra heat.
- Use Bone Broth: Swap the chicken broth for bone broth for additional nutrients, especially if you’re looking for a soup that’s not only tasty but also packed with collagen and other gut-friendly benefits.
- Low and Slow Simmering: Let the soup simmer on low heat for longer if you have the time. The longer it cooks, the more the flavors will meld together, giving you a richer, more complex taste.
- Freezing Tip: This soup freezes really well. Just leave out the cream if you’re planning to freeze it. When you reheat, add the cream to ensure the soup maintains its creamy texture.
Recipe Variations
- Dairy-Free Version: To make this soup dairy-free, swap the heavy cream for coconut cream or a non-dairy milk alternative like almond milk. You can also omit the cheese or use a dairy-free parmesan substitute.
- Vegetarian Version: For a vegetarian take, substitute the sausage with a plant-based sausage or hearty vegetables like mushrooms or tempeh. Use vegetable broth instead of chicken broth for a fully vegetarian option.
- Low-Sodium Version: If you’re trying to reduce sodium intake, go for low-sodium chicken broth and skip adding extra salt at the end. You can also use fresh herbs to boost the flavor without the salt.
- Slow Cooker Method: If you prefer a hands-off approach, you can throw all the ingredients (except the cream and kale) into a slow cooker and let it cook on low for 6-8 hours. Add the cream and kale in the last 20 minutes before serving.
