Who says soup is only for cold weather?
This Slow Cooker Summer Minestrone is loaded with fresh vegetables, chickpeas, tomatoes, zucchini and herbs, but unlike the hearty minestrone I crave in winter, I often enjoy this version at room temperature, just as many Italians do.
A drizzle of good olive oil.
A sprinkle of grated Parmesan.
Maybe a slice of crusty bread on the side.
Simple perfection.
And while it tastes wonderful served hot, I find it especially refreshing during the warmer months when I want something nourishing without feeling weighed down.

Ingredients and Substitutions
Tomatoes
Fresh garden tomatoes are wonderful here. But canned crushed tomatoes work beautifully too and are often what I use.
Chickpeas
Chickpeas add protein and fiber.
Not a fan?
Substitute:
- Cannellini beans
- Great Northern beans
- Kidney beans
- Pinto beans
Carrots, Potatoes, Celery and Onion
The classic soup foundation. No need to be exact here. Add a little more or a little less depending on what you have.
Red Bell Pepper
Adds sweetness and color. Yellow or orange peppers work just as well.
Zucchini
A summer favorite. Yellow squash can easily be substituted.
Vegetable Broth (affiliate link) or Water
Either works. Broth adds more flavor, but I’ve made this soup both ways.
Rice
A little rice helps give the soup body. White rice cooks quickly at the end. Brown rice can be substituted if you prefer whole grains.
Fresh Basil
Stirred in at the end for freshness and bright flavor.

Had lots of fresh vegetables from garden so I doubled the recipe except for adding a cup of rice instead of 1/2 a cup and turned it into stewuop (stew/soup). Added chicken broth to thin it out. It was sooo good after adding the olive oil & parm cheese. Thought I was back in Italy.
I wasn’t too sure about room temperature soup, but this one’s a keeper, especially on warm summer evenings! My kids actually liked it too, which is always a plus. Thanks for sharing!
Love this recipe Itโs so easy and delicious
Can I freeze this? Thanks!
Hi Olivia, I’ve never frozen this but believe it will be fine. ~Martha
This is so yummy, and a hit with my husband. The fresh basil is rocks it. It is on the “make again” list.
Thanks for letting me know Charlene! It’s on my list to make this week too ๐ ~Martha
