I love the smell of this Italian soup cooking in the slow cooker. If you have time in the morning, do a bit of chopping and toss it all into the cooker. Set on low for 8 hours or high for 4 and you’ll have a delicious soup waiting for you when you get home.

This is one of the easiest ways to get more veggies into your life. And, I almost always have these basic ingredients in my pantry (so should you). Canned tomatoes, veggie broth, beans, and basic vegetables… potatoes, carrots, celery, and pepper. The addition of spinach kicks it up a notch because we like to get our greens in every day.
You could also up the protein by adding your favorite seitan sausage links, cut into pieces or crumbled. For last night’s meal, I was inspired to add a bit of homemade soy yogurt that I’d made a few days ago. It added a nice tang and creaminess to the soup and was delicious.
Putting together these soup recipes are easy:
- Mulligatawny Soup
- Mary’s Vegetable Soup with Farro
- Hearty Vegetable Soup
- Creamy Curried Cauliflower Soup
I made this in my older Cuisinart slow cooker, but I also have an Instant Pot which is all the rage these days because it’s also a pressure cooker. There are different sizes of the Instant Pot. For my purposes, the 6 quart is plenty big. You can also purchase a clear lid to use when you’re done and just move the ceramic pot into the fridge to store leftovers.

Would love to make the slow cooker Italian soup with spinach but could you break this down to just 4 servings? I am a single person with a small crockpot.
Hi, There is actually a way to adjust the servings on the recipe and the number of ingredients will change. Give it a try, it’s inside the number of servings where little arrows show up if you scroll over it. Probably 1 serving is too small but try 2 servings. I realize that it’s kind of hard to figure .3 of a 14.5 ounce can of tomatoes, but luckily with soup, the exact measurements don’t matter. If you don’t mind freezing extra, you could save that for later when you don’t feel like cooking. Or would cutting the recipe in half work for your crockpot? That seems the simplest to me. I hope that helps.
