Ingredients for Kidney Bean Soup
For this recipe you will simmer in a large stockpot:
- Yellow onion: Or substitute white onion or sweet onion.
- Carrot: These are one of the richest vegetable sources of carotenoids, which help support vision and the immune system. They also provide powerful antioxidant protection as well and contain vitamin A, vitamin K, vitamin C, and dietary fiber.
- Fresh garlic cloves: Or simply use dried garlic powder instead if desired.
- Red kidney beans: You will need two 15-ounce cans of cooked beans for this recipe. Or substitute a different bean of choice such as white kidney beans (cannellini beans), etc.
- Canned diced tomatoes: Either regular or fire-roasted diced tomatoes.
- Vegetable broth: Be sure to use low sodium if desired.
- Orzo pasta: Orzo is a type of small pasta that is shaped like a large grain of rice. Most orzo is not gluten-free as it's typically made from semolina, which is a flour made from high-protein durum wheat. (But there are a couple brands that carry a gluten-free orzo made with rice flour and corn flour if you need a gluten-free option.) Otherwise feel free to substitute with rice, quinoa, or a gluten-free pasta if needed.
- Fresh baby spinach: Or you can substitute fresh kale.
- Dried oregano
- Dried basil
Veggies: Try it with other vegetables such as leeks, zucchini, yellow summer squash, celery, green peas, sweet corn, etc.
Herbs + spices: Change up the dried herbs and use an Italian seasoning blend, parsley, ground cumin, smoked paprika, thyme, bay leaves, etc.
Make it spicy: Include black pepper, red pepper flakes, cayenne pepper, chipotle in adobo sauce, or simply top with hot sauce to taste.
Make it "meaty": Stir in your favorite vegan ground beef crumbles or vegan sausage. I suggest cooking these separately according to package instructions. Then stir them in towards the end of cooking time.
Thickness: You can also add a couple tablespoons tomato paste or puree for a thicker, richer broth.
Garnish your bowl with fresh parsley, cilantro, or other herbs before serving for added flavor.
Store any leftovers in an airtight container in the refrigerator. We find they keep well for about 4-5 days.
So it's a great choice to make-ahead for meal prep, take-along lunches, etc.

Tried this soup for the first time this week. Very easy to put together and inexpensive, too, which is a bonus given the dramatic increase in grocery costs. Absolutely loved this dish, as did my husband and daughter (she ate all three of the leftovers!!). Thanks for sharing this delicious recipe. I followed it exactly, with no substitutions or variations, but would like to try it with brown rice as well.
Hi Jennifer! Wonderful to hear you three enjoyed this recipe. And definitely agree with finding more budget-friendly meals with these rising grocery costs. Thanks for sharing your kind feedback! Hope you enjoy it with the brown rice if you give that a try too! 🙂
Loved this! It was so comforting.
Wonderful to hear, Kathleen! Thanks so much for giving it a try and sharing your kind feedback!
Made this for lunch and used kale instead of spinach. Loved it!
So great to hear!
Could you substitute any type of bean for the kidney beans?
Hi Steph! Sure, feel free to substitute your own favorite bean here. Hope you enjoy if you give it a try! -Kaitlin
This looks very good!!! Can I freeze it?
Hi Natasha! You could, but I would suggest making & freezing it without the orzo (as pasta tends to turn quite mushy when freezing & reheating). Then cook the orzo separately and add it in when you're ready to thaw and reheat. Hope you enjoy if you give it a try!
Have you try doing this recipe in the instant pot? I wonder about how long it would take?
Good question - I've never made it in the instant pot, but I bet it'd work well! (I'm guessing maybe 10 minutes?)
Going to try this with a little pesto added.
I want to make this with real orzo (barley) instead of pasta orzo. Any tips for cooking? Should I cook the barley and then add it to the soup?

Hi Kira! Barley takes about twice as long to cook (and soaks up a bit more water) so I'd suggest cooking it separately and stirring it in. Or if you're cooking it with the soup, add another cup of broth (or more as needed). Hope you enjoy!
This was a total winner! Super easy, thick, hearty & yummy. I added 2 tbsp of tomato paste, made it twice in one week. Thank you! I have loved all of the recipes I have made from your blog
