Dried Rattlesnake Bean and Vegetable Soup

I had the pleasure last summer of growing rattlesnake beans for the first time. I had never heard of them and was intrigued because they can be eaten just like green beans when they’re young or eaten as dried beans when left to grow and dry on the vine. Anyone who’s grown green beans knows how quickly they can grow, so the advantage to growing rattlesnake beans is that if they go past their young, tender stage, you can let them go to dried beans and still enjoy them. Genius, I say! If you’ve been wondering how to grow rattlesnake beans, they’re easy to grow and delicious.

I ordered my beans from Territorial Seed Company and planted them in early May. Rattlesnake beans are pole beans, so you need to give them a fence or support to grow on and boy do these things grow. I did not have the foresight to take a picture of them on the vine but here’s a shot of them while they’re young:

Aren’t they beautiful? The dark purple striping makes a stunning contrast to the green pod and these really are delicious when harvested at this stage. If you’re wondering how to cook young rattlesnake beans, they can be cooked any way you cook regular green beans. They’re wonderful steamed, roasted and added to soups and other dishes. We had a very healthy harvest of these before I let them go to the drying stage.

Growing them here in Zone 5 was very easy for me. I planted the seeds against a garden fence with some compost and manure mixed in. These are very fast growers and occasionally I had to train the vines around the fence, to make sure they had some much-needed support. I harvested them as green beans until late July or early August and then let the rest of them mature and dry on the vine, picking them as they became fully dry. Then I shelled them and stored them in a storage container in my pantry, where they’ve kept well as I work my way through them.

As you can see, the dried beans are just as gorgeous as the green ones – their distinctive markings make it easy to see why they’re called rattlesnake beans.

So here we are, in the middle of a cold Midwestern winter, and what’s the best way to cook these dried rattlesnake beans? In soup, of course! Packed full of veggies, this is a great version of a clean-out-your-fridge recipe. Mine here simply reflects what I had on hand for veggies, so please don’t be afraid to use whatever you love and/or have on hand. There are no rules to veggie and bean soup, except that you make it with the veggies you enjoy. And if you don’t have dried rattlesnake beans, then use whatever beans you like. Don’t like beans? This is still a great vegetable soup recipe, so don’t be afraid to omit or change things up. Be prepared, this is a long list of veggies but don’t be daunted…I’m just cleaning out my fridge for soup…

Dried Rattlesnake Bean and Vegetable Soup Recipe

• 1 cup of dried rattlesnake beans
• 1 cup of small pasta, such as ditalini
• 1 tablespoon olive oil
• 3 cloves garlic, chopped
• 1/2 large white onion, diced
• 8-10 baby carrots, sliced
• 2 celery stalks, sliced
• 5 small sweet peppers, diced
• 4-5 medium-size turnip greens, tough stem removed and chopped
• 1 cup small spinach leaves, torn or chopped
• 1 small zucchini, diced
• 15 asparagus spears, tough ends removed and sliced
• 2 medium tomatoes, diced
• 1/4 teaspoon crushed red pepper flakes (optional)
• 1 teaspoon kosher salt
• 1/2 teaspoon black pepper
• 6 cups vegetable broth
• 4 cups water
• 1 cup bean broth
• 1 2-inch piece of Parmesan rind (optional)

In a medium saucepan, add dried rattlesnake beans and fill with water. Bring to a boil for 2 minutes, cover and remove from heat. Let sit, covered, for 1 hour. In the meantime, cook the pasta, prepare the veggies and start the soup.

In a medium saucepan, cook the ditalini or other small pasta for 10 minutes or just until al dente. Drain and rinse with cold water. Let sit until ready to use.

In a large stockpot, heat the olive oil over medium heat. Add garlic, onions, and carrots and cook just until they start to sweat, stirring a few times, about 5 minutes.

Add the rest of the veggies and continue to cook until they all start to wilt and soften, about 7 more minutes.  Season with pepper flakes (if using), salt and pepper and stir well. Add vegetable broth, water, bean broth, and Parmesan rind (if using).

Add the rattlesnake beans. You will not add the pasta until the soup is almost done. Bring to a boil, partially cover and reduce heat to a slow simmer.

Simmer for one hour or until beans are tender. Add pasta and bring back to a simmer. Remove from heat and serve.

We had a good 2 bowls of this before we sat back and wondered at the incredible flavor of these beans. Rattlesnake beans have a meaty, hearty flavor but cook quickly and stay tender. I love these beans and will definitely add them to my “things you should definitely grow in your vegetable garden” list.

Happy soup season everyone…here’s hoping for an early spring!
