Step‑by‑Step Instructions for Sausage and Lentil Soup

Step 1: Fry the Bacon
In a large skillet over medium-high heat, add diced bacon and cook for about 10 minutes, or until crispy and golden brown. Stir occasionally to ensure even cooking. Once done, transfer the crispy bacon to a plate lined with paper towels to drain excess fat while keeping the rendered fat in the skillet for added flavor in the soup.

Step 2: Brown the Sausage
In the same skillet with the remaining bacon fat, add Italian sausage over medium heat. Cook for 7-8 minutes, breaking it into bite-sized pieces as it browns. Look for a nice golden color on the sausage, which enhances the flavor. Once browned, remove the sausage and place it on the same plate as the bacon.

Step 3: Sauté the Vegetables
Using the residual fat in the skillet, add diced onions, celery, and red bell pepper. Sauté for 5-7 minutes, stirring often, until the vegetables are softened and fragrant. They should be translucent but still maintain some texture. This step builds the flavorful base for your sausage and lentil soup.

Step 4: Add Garlic
Toss in the minced garlic with the sautéed vegetables and cook for an additional 30 seconds. Stir frequently to release the garlic’s aromatic essence without burning it. The combination of garlic with the sautéed veggies will create an irresistible fragrance that signals flavor and warmth, perfect for the hearty soup.

Step 5: Transfer to Slow Cooker
Carefully transfer the sautéed vegetable mixture and the browned sausage to a slow cooker. Make sure to scrape the skillet to get all those flavorful bits that will enhance the sausage and lentil soup. This mix creates the cozy and savory base that will simmer together to build a rich flavor.

Step 6: Add Remaining Ingredients
Into the slow cooker, pour in the chicken broth, tomato sauce, rinsed lentils, dried oregano, and crushed red pepper flakes. Season the mixture generously with salt and pepper to taste. Stir well to combine everything, ensuring the lentils are submerged in the liquid, which allows them to cook evenly.

Step 7: Slow Cook to Perfection
Set your slow cooker to cook on high for 3-4 hours or on low for 6-8 hours. The soup is done when the lentils are tender and the flavors meld beautifully. Towards the end of cooking, you may choose to blend a portion of the soup for a creamier texture, adding a delightful twist to your sausage and lentil soup.

Step 8: Serve and Enjoy
Once cooking is completed, ladle the hearty sausage and lentil soup into bowls. For an additional touch, serve with a sprinkle of fresh herbs or a side of crusty bread. This soup is best enjoyed warm, enveloping you in its comforting flavors, making it the perfect dish for cozy nights in.

What’s the best way to store leftover sausage and lentil soup?
Store leftover soup in an airtight container in the refrigerator for up to 4 days. Ensure it cools completely before sealing the container. Reheat gently on the stovetop, adding a little chicken broth or water if it appears too thick.

What should I do if my lentils aren’t cooking properly?
Very! If your lentils seem too firm after the cooking time, it could be that they weren’t rinsed thoroughly, leading to texture issues. Next time, make sure to rinse them well before adding to the soup. If they still aren’t tender, extend the cooking time by 30-minute intervals until they reach your desired softness.
