Trick & Hearty Minestrone Soup
This hearty minestrone soup is thicker than most minestrone soups. Brimming with colorful vegetables, protein-rich beans, and aromatic herbs, it’s as delicious as it is satisfying. Feel free to add rice or pasta to the soup, too, and serve it with a slice of rustic homemade bread for a filling vegetarian meal. You’ll love this soup’s uniquely rich texture—every spoonful is different!
We’ve loved it on cold winter days, especially served in giant homemade bread bowls or topped with homemade croutons. It’s a soul-warming vegetarian soup that can easily be vegan by using vegetable broth and skipping the optional parmesan cheese topping.
This Is a Thick Minestrone Soup
This minestrone soup is much heartier than what we’re used to—almost like a chili—which is why I love it so much. The pasta/rice soaks up a lot of liquid, which helps thicken it up. I add a 6-ounce can of tomato paste (not the double-concentrated kind), which is more than most minestrone soup recipes. I also throw in fresh zucchini, carrots, celery, and spinach, plus lots of canned beans. There’s also garlic, onion, diced tomato, and a hefty dose of seasoning. There’s so much color and texture in 1 spoonful, how can you not be satisfied?!
Substitution Suggestions
This soup is pretty forgiving. Just as we do when making this biscuit vegetable pot pie or vegetarian shepherd’s pie, play around with the vegetables you use based on what you like. Here are the substitutions I’ve tried over the last several years, so I know they work wonderfully.
- Zucchini: You can leave this out, or use another squash instead. I’ve also used chopped mushrooms in its place.
- Kidney Bean & Butter Beans: I love this blend of beans, but you can use all kidney or all butter beans instead. Or substitute one or both for chickpeas, cannellini, borlotti, or great northern beans. Or substitute one for a drained can of corn.
- Green Beans: You can use chopped fresh green beans or frozen green beans instead. When I do this, I usually use around 1 and 1/2 cups. Add it when you add the other beans—they have enough time to cook and soften. No need to thaw if using frozen.
- Skip the Pasta/Rice: You can skip the pasta/rice. No changes needed. The soup will be a little more broth-y.
- Spinach: Feel free to use chopped fresh kale instead, or leave it out. If you want to use frozen spinach, add it in 10 minutes before the end of cooking instead of 5.
- Add Meat: Feel free to add 1 lb. of ground chicken, turkey, or beef. Cook it with the celery/carrots in step 1. Skip 1 can of the beans, and you may want to add another 1 cup (240ml) of broth. Or add 1–2 cups pre-cooked meat, such as chopped/shredded rotisserie chicken or ham, when you stir in the spinach. Sometimes I even add thinly sliced chicken sausage.
Whichever vegetables you use, I recommend sticking with the seasonings, tomato paste, and broth; these all make up the flavorful tomato base of the soup.
How to Freeze Minestrone Soup
This soup freezes wonderfully! Freeze in a large freezer container for up to 3 months. Thaw in the refrigerator the day before eating, then reheat on the stove until warm.
Can I Make This in a Slow Cooker?
If you want the minestrone soup to cook all day, here are the slow cooker directions. I also included these in the recipe card below. Prepare the soup through step 1 on the stovetop. Transfer to a slow cooker, then add everything else except for the rice/pasta and spinach. Allow to cook for 2 hours on low, then add the rice/pasta and spinach. Cook on low for 1 more hour.
Thick & Hearty Minestrone Soup
Ingredients
Method
- Heat the olive oil over medium heat in a large stockpot or dutch oven. Add the onion, carrots, celery, zucchini, garlic, Italian seasoning, salt, pepper, and thyme. Cook, stirring occasionally, for 6–7 minutes as the vegetables soften up and let out some juices.
- Add broth, water, red wine vinegar, bay leaf, all the beans, diced tomatoes, and tomato paste. Bring to a boil, then add uncooked rice or pasta. Cover and simmer for 35 minutes. Stir in the chopped spinach and simmer for 5 more minutes. Remove bay leaf.
- Serve soup warm in homemade bread bowls (or regular bowls, of course!) and top with fresh parmesan cheese, if desired.
- Keep leftovers in a large covered container in the refrigerator for up to a week. To reheat, simply pour into a pot over medium heat and cook until warm. Feel free to add more broth to the leftovers as it cooks if it is too thick—I always do. (It thickens in the refrigerator as the veggies and rice/pasta soak up the liquid.)
Notes
- Make Ahead Instructions—Freezing: Soup freezes wonderfully! Freeze for up to 3 months. Thaw in the refrigerator the day before eating, then reheat on the stove until warm.
- Special Tools (affiliate links): Large Pot or Dutch Oven (such as this Le Creuset Dutch Oven or Lodge Dutch Oven)
- Zucchini: You can leave this out, or use summer squash instead. I’ve also used chopped mushrooms in its place.
- Italian Seasoning: If you don’t have Italian seasoning, you can use any combination of Italian spices that you like. Dried basil, rosemary, oregano, etc.
- Broth: Anywhere between 6–7 cups (about 1.5L) of broth is great. I use 7, and then add a little more when I reheat leftover soup. The rice or pasta soaks up a lot of liquid.
- Vinegar: The vinegar balances out all the flavors. A few splashes of a dry-ish red wine works too!
- Kidney Bean & Butter Beans: I love this blend of beans, but you can use all kidney or all butter beans instead. Or substitute one or both for chickpeas, cannellini, borlotti, or great northern beans. Or substitute one with a drained can of corn.
- Green Beans: You can use chopped fresh green beans or frozen green beans instead. When I do this, I usually use around 1 and 1/2 cups. Add it when you add the other beans—they have enough time to cook and soften. No need to thaw if using frozen.
- Rice/Pasta: Use brown or white rice or any dry pasta you like best. Stick with smaller-shaped pasta so it fits on your spoon—I usually use orzo. You can also skip the rice/pasta. The soup will be thinner.
- Spinach: Feel free to use chopped fresh kale instead, or leave it out. If you want to use frozen spinach, add it 10 minutes before the end of cooking instead of 5.
- If You Want to Add Meat: Feel free to add 1 lb. of ground chicken, turkey, or beef. Cook it with the celery/carrots in step 1. Skip 1 can of the beans, and you may want to add another 1 cup (240ml) of broth. Or add 1–2 cups pre-cooked meat, such as chopped/shredded rotisserie chicken or ham, when you stir in the spinach.
