Step-by-Step Instructions for Hearty Lentil and Sausage Soup
Now that you have all your ingredients ready, let’s dive into the simple yet rewarding process of making this soup. Follow these steps, and you’ll have a delicious, comforting dish ready in no time.
1. Prepare the Lentils
First, rinse the lentils thoroughly under cold water. This step is important to remove any dust or impurities. Once they’re rinsed, place the lentils directly into your slow cooker. The lentils will absorb the flavors of the broth and seasonings as they cook, making them the perfect base for this hearty soup.
2. Sauté the Vegetables and Sausage
While the lentils are waiting, heat olive oil in a skillet over medium-high heat. Add the finely chopped onion and diced celery, sautéing for about 3-4 minutes until they soften. Then, toss in the minced garlic and cook for an additional minute. This will release the garlic’s fragrance and deepen the flavor of the soup base.
Next, add the sausage to the skillet. Break it up into smaller pieces as it cooks. You want the sausage to be fully browned and cooked through. Once the sausage is ready, transfer the entire mixture (sausage, vegetables, and all) into your slow cooker with the lentils.
3. Add the Broth, Tomatoes, and Seasonings
To your slow cooker, add the 4 cups of broth—beef or chicken broth works wonderfully. Then, pour in the diced tomatoes and fire-roasted tomatoes for an added layer of texture and flavor. Toss in the bay leaves, Italian seasoning, kosher salt, black pepper, and red pepper flakes to taste. Stir everything to combine, ensuring that the lentils are fully coated with the seasonings.
4. Slow Cook the Soup
Cover the slow cooker and let it cook on low for 7-8 hours or on high for 4-5 hours. You’ll know the soup is done when the lentils are tender but not mushy. The slow cooking process allows the flavors to blend together, making every spoonful a savory delight.
5. Add the Spinach
When you’re ready to serve, turn the slow cooker to high and stir in the roughly chopped fresh spinach. If the soup feels too thick, add up to 2 more cups of broth to reach your desired consistency. Let it cook for another 10-15 minutes until the spinach is wilted and tender.
6. Serve and Enjoy
Now, it’s time to enjoy your creation! Ladle the soup into bowls and, if desired, top with grated Parmesan cheese, fresh parsley, or a slice of crusty bread. The rich flavors and comforting texture will make each bite a delightful experience.
