What is Minestrone Soup?

It is a tomato-based dish that originated in Italy, which includes pasta and beans and vegetables like celery and carrots as the key ingredients. It initially started as a staple food that utilizes leftover veggies and was somehow regarded as a poor man’s food.

But throughout the centuries, it remained to be a favorite not only among the Italians but people all over the world. And you may use fresh vegetables, of course!

What vegetables go into it?

Tomato, carrots, celery, and aromatics like garlic and onion are the typical ones. This recipe calls for an addition of zucchini, butternut squash, and baby spinach. The beans are green and pink. Aside from the diced tomato, tomato paste is also added.

You can vary this line-up as long as you have the basic ones. Then, you can add in any vegetables that you have on hand like potatoes or those in season.

How to make Slow Cooker Vegetarian Minestrone Soup:

  1. Sauté: Heat up the olive oil and sauté the garlic and onions.
  2. Combine: In the crockpot, put the rest of the veggies along with the spices and seasonings except for the spinach and parsley.
  3. Cook: Cook for 6 to 8 hours on low or 3 to 4 hours on high.
  4. Add the pasta and other veggies: In the last thirty minutes or so, add in the pasta and spinach and cook on high.
  5. Serve: Garnish with parsley and parmesan cheese if you like. Then, serve warm!
