Homemade Minestrone Soup (Slow Cooker)

Homemade Minestrone Soup (Slow Cooker)

An easy to make, Minestrone soup recipe that tastes 1000 times better than the Olive Garden’s version! My minestrone soup is loaded with good for you veggies, like spinach and zucchini. It’s also protein packed with red kidney beans and great northern beans. You’ll be full for hours from this healthy, nutritious soup!

How about I throw a bunch of ingredients (say, veggies, beans, and pasta) into a crockpot and call it dinner? This slower cooker minestrone soup is probably going to be the easiest thing you’re ever going to cook. And the best part? You didn’t even need to turn on the stove!

I wonder if it’s even legal for me to call this a minestrone soup recipe? It’s ingredients that get tossed into the slow cooker and a few hours later, they come out in the form of a soup. Don’t you just love lunches and dinners like that? This gal right here is a big fan of those kinda meals.

So guys, I have news. I ♥ vegetables. And you already knew that. And now you know it even more.

My hope for you with this soup → that you make this on a really chilly and busy October night. It’s absolutely perfect for those days/nights when you have only 3,018,857 things to get done, and the fact that the crockpot is adulting for you and taking on the dinner responsibilities for the evening means you have the 30 minutes you would’ve spent making dinner to do what. ever. you. like.

Real excitement right there. Ideally, that would happen in a big, comfy chair with a good book and a warm blanket. These oh so rare, picture-perfect moments are brought to you by my slow cooker minestrone soup recipe.

Why this is the best minestrone soup recipe:

Shall I dare say my minestrone soup recipe is better than the Olive Garden’s version? Yes, I think I will. Don’t get me wrong; I first fell in love with Minestrone soup at the Olive Garden. It actually set the expectation of what a minestrone should be for me. The canned stuff was absolutely no good at all. And after researching the interweb until there weren’t any more recipes left to research, I decided to develop my own recipe.

So what makes my recipe unique and so much better? Well, I’ve got a secret ingredient. Any guesses? Okay, I’ll give you a hint. It’s in the picture above. And it’s a red blob. No, not the diced tomatoes, the other red blob.

*ShhhI’m only sharing this with you because we’re friends. Ready for it?

Homemade Sun-dried tomato pesto!

That super concentrated flavor of tomato pesto is exactly what minestrone soup needs. Plus, the basil, parmesan, and pine nuts in the pesto add such a great, full-bodied flavor to the soup.

Also, since we’re sharing secret ingredients and all, toss in a few parmesan rinds into the minestrone soup. For herbs, I used dried oregano, fresh rosemary (because I had fresh on hand, dried is fine too), and a few bay leaves.

TIPI should mention that this does make quite a batch of soup. So if you’re planning on making this for weekly lunches, I suggest cooking and keeping the pasta separately. Then you can add some to each serving before reheating.

This slower cooker minestrone soup is exactly what you need to warm up on a chilly evening. I served it with a few slices of baguette, toasted and rubbed down with a garlic clove.

We dipped, we dunked, and sipped, slurped soup (say that 3x fast) like it was our job. Garlic bread pairs beautifully with minestrone soup! It was a good evening. 🙂
