Whether you’re meal prepping for the week or need a last-minute dinner idea, this soup is versatile and foolproof.

The Magic of the Instant Pot ✨

Before diving into the recipe, let’s talk about why the Instant Pot is a game-changer for busy cooks. It combines the functions of a pressure cooker, slow cooker, and sauté pan, making it perfect for soups like this one. The sauté function lets you brown the sausage and onions to deepen the flavor, while the pressure cooking feature ensures everything cooks evenly and quickly.

Step-by-Step Guide to Making Keto Tuscan Soup

1. Gather Your Ingredients 🍽️

First, let’s talk about the stars of this soup. Each ingredient plays a role in building the rich, creamy, and savory profile.

Italian Sausage: Use ground Italian sausage (mild or spicy) for robust flavor.
Onion and Garlic: Aromatic staples that provide a fragrant base.
Cauliflower: The perfect low-carb substitute for potatoes.
Sun-Dried Tomatoes: For a tangy, umami punch.
Spinach or Kale: Adds vibrant color and nutrients.
Chicken Broth: Forms the savory backbone of the soup.
Heavy Cream: The key to that luscious, creamy texture.
Parmesan Cheese: Enhances the soup with nutty, salty richness.

Each of these ingredients is keto-friendly and contributes to the overall flavor and texture.

2. Sauté for Maximum Flavor

Using the sauté function on your Instant Pot, brown the Italian sausage until fully cooked. This step is crucial because browning the sausage adds depth to the soup. As the sausage cooks, it releases flavorful oils that will infuse the soup base.

Pro Tip: Break the sausage into small crumbles as it cooks to ensure even browning.

Once the sausage is done, transfer it to a plate and set it aside. Add diced onions to the pot and sauté until they’re soft and translucent, about 3-4 minutes. Toss in minced garlic and cook for an additional 30 seconds to release its aroma.

3. Deglaze the Pot 🍷

Here’s where the magic happens. Add a splash of chicken broth to the pot and scrape up any browned bits stuck to the bottom. These caramelized bits are flavor gold, so don’t skip this step!

4. Build the Soup Base

Now it’s time to add the rest of the ingredients. Toss in cauliflower florets, sun-dried tomatoes, and the remaining chicken broth. Season with salt, pepper, and a pinch of red pepper flakes if you like a little heat.

5. Pressure Cook to Perfection

Seal the Instant Pot lid and set it to Manual (High Pressure) for 5 minutes. Yes, you read that right—just 5 minutes! The pressure cooking process allows the cauliflower to become tender while infusing the broth with all those wonderful flavors.

6. Add Creamy Goodness

Once the cooking cycle is complete, perform a quick release to safely release the steam. Open the lid, and take a moment to inhale the incredible aroma. Stir in the heavy cream and cooked sausage, then switch the Instant Pot to the sauté function again.

Let the soup simmer for 2-3 minutes to thicken slightly. Toss in fresh spinach (or kale) and let it wilt into the soup.

Pro Tip: Add the spinach just before serving to keep it bright and tender.

7. Garnish and Serve

Ladle the soup into bowls and top with a generous sprinkle of grated Parmesan cheese. For an extra burst of flavor, drizzle with a touch of olive oil or a sprinkle of red pepper flakes.

Tips for Success 🌟

1. Use Quality Sausage

The flavor of this soup hinges on the sausage, so opt for a high-quality brand with no added sugar or fillers.

2. Don’t Skip the Deglazing

Those browned bits stuck to the pot are essential for flavor—don’t let them go to waste!

3. Customize Your Greens

If you’re not a fan of spinach, kale or Swiss chard are excellent alternatives.

Storage and Meal Prep 🥣

This soup stores beautifully, making it ideal for meal prep. Simply let the soup cool completely, then transfer it to airtight containers.

Refrigerator: Store for up to 4 days.
Freezer: Freeze in portions for up to 3 months. Thaw overnight in the fridge before reheating.

Reheat the soup gently on the stove or in the microwave, stirring occasionally to prevent the cream from separating.

Delicious Variations to Try 🥄

Mushroom Lover’s Twist: Add sliced mushrooms for an earthy touch.
Cream Cheese Boost: Stir in 2 ounces of cream cheese for an ultra-creamy texture.
Herb Explosion: Add fresh basil or thyme for a fragrant finish.
