A hearty vegetarian meal that’s ready in less than 30 minutes- this Instant Pot Minestrone Soup with Kale is a healthy weeknight hero. This soup is loaded with fresh veggies and fiber-rich kale and beans, and can be made vegan by using vegan pesto, and omitting the parmesan cheese topping, or replacing it with a vegan parmesan, such as this one from Love and Lemons.

This vegetarian minestrone soup is so richly flavored and comforting, and is a huge favorite among friends and family. And how can you beat a soup that from prep to plate is ready in UNDER 30 MINUTES?!

Prepping the ingredients

This quick minestrone soup comes together very quickly, and it helps to have all of your ingredients prepped and read to go. You could even do this the night before, so it’s all waiting for you when you get home from work.

I like to chop up all of my veggies in advance, so they are ready to add to the pot quickly. The carrots, celery and onion will go in first, followed by the garlic, then the zucchini or squash, and last but not least- the kale. So if doing the prep work in advance, separate the veggies accordingly.

To make the soup, you will need:

  • Olive oil.
  • 2 ribs of celery with leaves, finely chopped. The leaves are packed with flavor!
  • A small onion.
  • 3 medium carrots. You can dice them or slice them.
  • Dried oregano, dried basil, dried thyme, smoked paprika, red pepper flakes and bay leaves.
  • Garlic.
  • Tomato paste.
  • White wine, such as Pinot Grigio or Sauvignon Blanc. No sweet wines.
  • Diced zucchini or yellow squash.
  • A can fire roasted diced tomatoes.
  • Vegetable broth.
  • Prepared pesto (homemade or jarred).
  • Chopped fresh parsley, plus more for serving.
  • A can of cannellini beans and a can of kidney beans.
  • Mini shell pasta, or ditalini pasta.
  • Chopped kale, tough stems removed.
  • Apple cider vinegar.

Cooking the Italian Minestrone Soup

Once all your ingredients are prepped and ready to go, you’ll start by setting the Instant Pot to sauté, and briefly sweating the celery, onion and carrots until the onions are translucent.

Building the flavor in the quick minestrone soup

Sautéing the vegetables first helps to give them a nice texture, and bring out their flavor. And to build the flavor even more, once the veggies are softened, the next step is cooking out the spices, tomato paste and garlic briefly to intensify their flavors. This soup cooks FAST- so building flavor is key.

Final steps for great Instant Pot Minestrone Soup

Once you’ve briefly cooked the spiced, tomato paste and garlic with the veggies, it’s time to deglaze the pan with some white wine. If you’re not a fan of cooking with wine, you could skip it- but I highly recommend adding the wine. It give the soup great depth of flavor.

Once the wine cooks a few minutes and absorbs into the veggies, you’ll add; a couple bay leaves, fire roasted diced tomatoes, pesto, beans, pasta and zucchini or squash.

Set the Instant Pot to High Pressure, then do a quick release. Set it back to sauté, and cook the kale for about 5-7 minutes, and that’s it!

Making the soup on the stovetop

For the stovetop version, you’ll follow almost all the steps, identically, with the exception of the high pressure simmer. The stovetop version takes about 15 minutes.
