Minestrone Soup Ingredients
- Fresh Veggies: You can also use seasonal veggies or whatever you have on hand, like celery, carrots, zucchini, yellow onion, spinach, garlic, and parsley. Other veggies that go well are green beans, potatoes, squash, yellow zucchini, and kale.
- Beans: You can use any canned beans you have on hand – red kidney beans, white kidney beans(cannellini), and northern beans. Chickpeas will also work. In this recipe, I pre-cooked the kidney beans in the instant pot. Soak the beans insufficient hot water for 2 hours and cook them for 25 minutes at high pressure in the instant pot. Then used them in this recipe.
- Pasta: I have used shell pasta here, but you may use elbow macaroni or any small pasta. You can use gluten-free if you’d like.
- Diced tomatoes: I have used fresh diced tomatoes in this recipe. But you can also use one 14 oz can of diced tomatoes which is about 2 cups.
- Tomato Sauce: To make the soup thicker and tomato-based, I have used store brought one 8 oz can of tomato sauce which is about 1 cup. But you can either skip it or just blanch & puree 2 tomatoes and then add.
- Vegetable Broth: Try using low sodium store brought vegetable broth or simply use water.
- Dried herbs: I have used dried Italian seasoning, or you can also use a mix of basil, oregano, rosemary, thyme
- Parmesan, for serving (skip if vegan) and use nutritional yeast instead.
The best part about this vegetarian minestrone soup recipe is its versatility! Traditionally minestrone is a little thicker, but again you adjust as per your preference and taste.
