Ingredients for Kidney Bean Soup

For this recipe, you'll simmer in a large stockpot on the stove:

Yellow onion: Or you can substitute white onion or sweet onion.
Carrot
Fresh garlic cloves: I like the taste of fresh, but you can use dried garlic powder instead if desired.
Red kidney beans: You'll need two 15-ounce cans of cooked kidney 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 work great.
Vegetable broth: Be sure to use low sodium if desired.
Orzo pasta: Orzo is a type of small pasta that's shaped like a large grain of rice. Most orzo isn't gluten-free as it's typically made from semolina, which is a flour made from high-protein durum wheat. (See below for gluten-free options if needed!)
Fresh baby spinach: Or you can substitute fresh kale (or a combination of both!) if you prefer.
Dried oregano and basil: You can also add salt and black pepper to taste.
Vinegar: This is completely optional, but you can stir in one tablespoon of apple cider vinegar or balsamic vinegar at the end of cooking time. This helps season the soup and deepens the flavor. It gives it that something "extra"!

Customizing

Veggies: Swap in other vegetables such as leeks, zucchini, yellow summer squash, celery, green peas, sweet corn, green beans, potato, sweet potatoes, red bell pepper, 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.

Make it gluten-free: Use gluten-free orzo, such as Barilla's chickpea orzo, or a rice & corn orzo. Banza also makes a chickpea "rice" that's roughly the same size and shape as orzo. Or you can simply substitute the orzo altogether with rice, quinoa, or a small gluten-free pasta instead.

Thickness: You can also add a couple tablespoons tomato paste or puree for a thicker, richer broth.

Serving

Fresh herbs: Garnish your bowl with fresh parsley, cilantro, or other herbs before serving for added flavor.

Storing

After it cools completely, store leftovers in an airtight container in the refrigerator. I find it keeps well for about 4-5 days. (So it's a great choice for make-ahead meal prep, take-along lunches, etc.)

Course: Main Dish, Soup

Cuisine: Gluten-Free Option, Oil-Free, Vegan

Servings: 5

Ingredients

1 yellow onion
2 carrots
4 cloves garlic
30 oz. canned kidney beans*
15 oz. can diced tomatoes
6 cups vegetable broth
3/4 cup orzo pasta
3 cups baby spinach
1 tsp. dried basil
1/2 tsp. dried oregano

Stir-in (optional):

1 Tbsp. apple cider vinegar or balsamic vinegar
3 Tbsp. fresh parsley, cilantro, or basil

Instructions

Dice onion and carrot.
In a stockpot over medium-high heat, sauté onion and carrot for 7-8 minutes. (I use 3 Tbsp. water/broth for no-oil sauté method, adding more as needed.)
Meanwhile, mince garlic.
When onion is translucent, add garlic, basil, and oregano. Stir and sauté 1-2 minutes until garlic is fragrant.
Add broth, tomatoes, and kidney beans (rinsed and drained). Bring to a light boil.
Then add orzo and stir well. Cover, reduce heat, and simmer for about 10-12 minutes, or until orzo is tender. Stir occasionally to prevent orzo from sticking to the bottom. (Take care not to overcook the orzo. Be aware it will continue to expand and soak up the broth as it sits.)
Roughly chop spinach and stir in during the last couple minutes of cooking. Salt and pepper to taste.
Stir in the optional vinegar and fresh herbs before serving if desired.

Notes

*Kidney beans: 30 oz. equals two regular 15 oz. cans.

For gluten-free: Orzo typically isn't gluten-free. So use a GF orzo, such as Barilla's chickpea orzo, or a rice & corn orzo. Banza also makes a chickpea "rice" that's roughly the same size and shape as orzo. Or you can simply substitute the orzo altogether with rice, quinoa, or a small gluten-free pasta instead.

Vegetables: Add in whatever else sounds good like kale, leeks, zucchini, celery, potato, green beans, bell pepper, etc.
