🛠️ Step-by-Step Instructions
1. Brown the Sausage
In a large skillet, cook the Italian sausage over medium-high heat, breaking it up with a spoon, until it is fully browned. Drain off most of the excess grease, leaving about 1 tablespoon in the skillet.
Add the chopped onion to the skillet and sauté for 3 minutes until softened. Stir in the minced garlic and red pepper flakes and cook for 1 minute until fragrant.
2. Combine Ingredients in Slow Cooker
Transfer the cooked sausage and sautéed aromatics to the slow cooker insert.
Add the sliced potatoes, chicken broth, dried oregano, and dried thyme. Season generously with salt and pepper.
3. Cook Low and Slow
Cover the slow cooker and cook on LOW for 7–8 hours or on HIGH for 4–5 hours, or until the potatoes are completely fork-tender.
4. Finish the Soup
About 10 minutes before serving, remove the lid. Stir in the heavy cream and the chopped kale.
Cover the slow cooker again and cook for an additional 10 minutes, or until the kale has wilted and softened but still retains its vibrant green color.
5. Serve
Ladle the Crock-Pot Tuscan Sausage Soup into bowls. Serve piping hot, garnished with a generous sprinkle of grated Parmesan cheese and crusty bread for dipping.
💡 Expert Tips
- Don’t Skip the Browning: Searing the sausage first is crucial. This step develops deep, caramelized flavor (the Maillard reaction) that you won’t get by simply adding the raw sausage to the slow cooker.
- Timing the Cream: Always add the cream and kale right at the end. Dairy can curdle if cooked for hours on high heat, and adding the kale late keeps its bright color and prevents it from becoming too soggy.
- Spice Adjustment: If using mild sausage, the 1/2 teaspoon of red pepper flakes adds a nice little kick. If you use hot Italian sausage, you may want to reduce or omit the red pepper flakes.
❓ FAQs
Q: The soup is too thin. How can I thicken it?
A: You have two easy options:
- Mash Potatoes: Scoop out about 1/2 cup of the cooked potatoes, mash them into a paste, and stir them back into the soup. The starch acts as a natural thickener.
- Cornstarch Slurry: Whisk 1 tablespoon of cornstarch with 2 tablespoons of cold water. Stir this slurry into the simmering soup during the final 10 minutes of cooking.
Q: Can I use spinach instead of kale?
A: Yes, you can. Spinach wilts much faster than kale, so add it along with the heavy cream and let it wilt for only 2–3 minutes before serving.
Q: Can I use dried herbs?
A: Yes, dried herbs work perfectly in the slow cooker as the long cooking time allows their flavors to fully permeate the soup. Just be sure to reduce the quantity compared to fresh herbs.
