Ingredients

To prepare this Sausage and Pesto Minestrone Soup, gather the following:

• 16 ounces mild Italian sausage
• 1 medium onion, chopped
• 1 1/2 cups celery, chopped
• 1 1/2 cups carrots, chopped
• 1 6-ounce can tomato paste
• 2 tablespoons garlic, minced
• 1 tablespoon dried oregano
• 1 15-ounce can Italian-style diced tomatoes
• 5 cups chicken broth
• 1 15-ounce can cannellini beans, drained and rinsed
• 1 15-ounce can red kidney beans, drained and rinsed
• 1 cup zucchini, chopped
• 1 cup yellow squash, chopped
• 1/2 cup dry ditalini pasta
• 2 cups baby spinach
• Basil pesto, to garnish
• Grated Parmesan cheese, to garnish

Optional substitutions

For a plant-based version, substitute vegan Italian sausage or omit the sausage and add extra beans or sautéed mushrooms for texture. If you need gluten-free, use a gluten-free pasta or omit the pasta and serve the soup over cooked rice or farro.

How to Make Sausage and Pesto Minestrone Soup

Follow these steps to make a flavorful, well-balanced minestrone:

1. In a large soup pot over medium heat, brown the Italian sausage until cooked through. Drain any excess fat.
2. Add the chopped onion, celery, carrots, garlic, tomato paste, and oregano. Sauté about 5 minutes until the vegetables begin to soften and the tomato paste darkens slightly to build flavor.
3. Stir in the diced tomatoes and chicken broth. Bring the mixture to a boil, then reduce heat and simmer for 30–45 minutes, until the carrots are tender and flavors have melded.
4. Add the cannellini beans, red kidney beans, zucchini, yellow squash, and the dry ditalini pasta. Simmer another 8–12 minutes until the pasta is al dente and the vegetables are tender.
5. Remove the pot from heat and stir in the baby spinach; the residual heat will wilt it quickly.
6. Season with salt and freshly ground black pepper to taste.
7. Ladle into bowls and garnish each serving with a teaspoon of basil pesto and a sprinkle of grated Parmesan cheese.

Slow cooker instructions

Brown the sausage and sauté the vegetables and tomato paste on the stovetop (steps 1–2), then transfer everything to a slow cooker. Add broth and tomatoes and cook on low for 4–6 hours. Stir in beans, zucchini, squash and pasta during the last 10–15 minutes so the pasta does not overcook. Add spinach just before serving and garnish as directed.

Helpful Tips

• Adjust the heat: Swap mild Italian sausage for hot if you prefer a spicier soup.
• Pasta tips: If you plan to reheat leftovers, cook the pasta separately and add portions to bowls when serving to prevent it from turning mushy.
• Consistency: Add extra chicken broth or water if the soup thickens as it sits; simmer briefly to combine.
• Pesto and cheese: A spoonful of fresh pesto at the table brightens the soup and Parmesan adds savory depth—both are optional but recommended.

Cooking Tips

• Build flavor early: Browning the sausage and caramelizing the tomato paste with the vegetables is essential for a deep, rich base.
• Use a heavy pot: A Dutch oven or large soup pot helps distribute heat evenly for steady simmering.
• Fresh pesto: While store-bought pesto is convenient, fresh basil pesto made at home will lift the overall flavor if you have time to make it.

Serving Suggestions

Serve this Sausage and Pesto Minestrone Soup with crusty Italian bread or garlic bread for dipping. A simple green salad with a light vinaigrette balances the richness of the soup. For a heartier meal, offer grated Parmesan and extra pesto on the side so everyone can customize their bowl.

Storage and Leftovers

Refrigerate: Store leftovers in an airtight container in the refrigerator for 3–4 days.

Freeze: The soup freezes well if you leave out the pasta. Freeze in meal-sized portions for up to 3 months; thaw overnight in the refrigerator before reheating.

Reheat: Warm gently on the stovetop over medium-low heat, stirring occasionally. If the soup is too thick after chilling, add a splash of broth or water when reheating.

Leftover ideas: Turn leftovers into a baked pasta casserole by adding cooked pasta and topping with mozzarella before baking, or use the soup as a flavorful base for risotto.

Frequently Asked Questions (FAQs)

Can I use other types of beans?

Yes. Chickpeas, black beans or lentils work well and will change the texture and flavor slightly—choose what you prefer or what you have on hand.

Can I freeze this soup?

Yes. Freeze without pasta for best results. Add cooked pasta when reheating for optimal texture.

What can I substitute for sausage?

Ground turkey or beef are good alternatives. For a vegetarian option, use plant-based sausage, extra beans, or a mix of mushrooms and lentils for added heartiness.
