Gathering Your Ingredients
To create this delightful slow cooker minestrone, you’ll need a foundational liquid base of 4 cups (880g) of reduced-sodium vegetable broth. Complementing
this are two 14.5-oz. (411g) cans of no-salt-added diced tomatoes, which provide a rich tomato flavor without excessive sodium. For protein and texture, incorporate two 15-oz. (425g) cans of reduced-sodium Cannellini beans, rinsed and drained. The essential mirepoix forms with two medium (120g) carrots, two medium (80g) celery stalks, and one small (70g) white or yellow onion, all finely chopped. Aromatic depth comes from 2 tsp of Italian seasoning and two bay leaves, seasoned with 1/4 tsp salt and 1/2 tsp black pepper. For the final cooking stage, you'll add 2 cups (480g) of water, 1/2 cup (50g) of uncooked elbow macaroni, one medium (200g) zucchini, and 2 cups of coarsely chopped fresh spinach. Optional garnishes like Parmesan cheese and fresh basil can elevate the finished dish.
Slow Cooker Assembly
Initiate the minestrone-making process by combining the fundamental elements directly within your slow cooker. Pour in the 4 cups (880g) of reduced-sodium vegetable broth, followed by the two cans of no-salt-added diced tomatoes, ensuring their juices are included. Add the two cans of reduced-sodium Cannellini beans, which contribute a creamy texture and substantial protein. Next, introduce the chopped vegetables: the two medium carrots (120g), two medium celery stalks (80g), and one small white or yellow onion (70g). For seasoning and aroma, sprinkle in the 2 tsp of Italian seasoning, place in the two bay leaves, and add 1/8 tsp each of salt and black pepper. Once all these ingredients are in the slow cooker, cover it securely. This mixture will then cook gently, allowing the flavors to meld beautifully.
Cooking and Finishing Touches
Allow the combined ingredients in the slow cooker to cook for either 6–8 hours on the low setting or 3–4 hours on the high setting. This extended, gentle cooking period is crucial for developing a deep flavor profile and tenderizing the vegetables. About thirty minutes before you plan to serve the soup, it's time to add the final components. Stir in 2 cups (480g) of water to adjust the consistency, followed by the 1/2 cup (50g) of uncooked elbow macaroni, the chopped medium zucchini (200g), and the 2 cups of coarsely chopped fresh spinach. Cover the slow cooker again and let these ingredients cook for the remaining thirty minutes, ensuring the pasta is tender and the spinach has wilted. Before serving, remember to remove the two bay leaves. Taste the soup and adjust the seasoning with additional salt and black pepper as needed. Ladle the hot minestrone into bowls and, if desired, garnish with grated Parmesan cheese and fresh basil for an extra burst of flavor and color.
