Ingredients

1 cup (100 g) diced celery
2 cups (300 g) chopped onion
2 cups (200 g) red bell pepper, diced (about 1 large pepper)
2 cloves garlic, minced
A pinch (0.2 g) red pepper flakes
¼ cup (60 g) tomato paste
2 lbs (900 g) zucchini, cut into bite-sized pieces

5 fresh plum tomatoes, diced (about 500 g)
½ tsp (1 g) freshly ground black pepper
2 quarts (2 L) low-sodium chicken broth or vegetable broth
1 cup (100 g) coarsely grated Parmesan cheese
1 tbsp (5 g) Parmesan rind (optional)
2 tbsp (6 g) chopped fresh basil
1 fresh thyme sprig
1 tbsp (5 g) Parmesan cheese for garnish (optional)

Step-by-Step Directions

In a large pot or Dutch oven, heat olive oil over medium-high heat. Add sausage and cook 5 minutes, breaking it into small pieces until browned.
Add onion, celery, and bell pepper. Sauté 4 minutes until starting to soften.
Push sausage and veggies to the side. Lower heat to medium. In the center, add garlic, red pepper flakes, and tomato paste. Cook 2 minutes until fragrant.

Stir in tomatoes, zucchini, black pepper, broth, Parmesan rind, grated Parmesan, basil, and thyme. Mix well.
Bring to a gentle simmer. Cover and cook 10–15 minutes until zucchini is tender.
Remove thyme sprig, adjust seasoning, and serve hot with extra Parmesan.

Olivia’s Cooking Tips

For a lighter version, swap sausage for ground turkey or chicken.
If you want a creamier texture without cream, blend half the soup and stir it back in.
Fresh tomatoes give the best flavor, but canned can work in a pinch.

The Parmesan rind is optional, but it’s the secret weapon for deep, savory flavor.

A Little Kitchen Story

I created this vegetable sausage soup on a Sunday when my fridge was full of zucchini from the farmer’s market. My husband peeked into the pot and said, “Looks healthy.” (Translation: “Will I like it?”) Fast forward to him ladling a third bowl, declaring it “restaurant-worthy.” That’s when I knew I’d struck gold—a soup that makes you feel virtuous while tasting indulgent. Now, it’s in heavy rotation whenever zucchini season hits.
