Arugula Cannellini Bean Barley

Why You’ll Love This Recipe

Cannellini beans make this barley filling for a vegetarian side dish or main dish. Between the beans and grains, this is a hearty recipe that you can make in less than 20 minutes.

Pesto is the best no-cook sauce ever. With so much flavor and not much effort, you can make the arugula pesto for this barley recipe. As I always say, pesto, no matter the base ingredient, is an instant flavor boost. That’s why I use it so much in my cooking.

You can eat this white bean barley warm, at room temperature or cold, so it is very helpful for meal planning. You can even add more arugula and turn it into a grain salad.

The Ingredients

Barley, cannellini beans, arugula, almonds, parmesan, olive oil, salt and pepper.

This is what you need:

  • Barley: I simmer the grains in water on the stove. You also can use low-sodium vegetable broth. Instead of pearled barley, you can substitute with brown rice or farro, which both have grains similar in size to barley. I prefer them over quinoa.
  • White beans: I like cannellini beans, but you can use smaller beans such as great northern beans or navy beans instead. When they are smaller, they will be more distributed throughout the barley.
  • Baby arugula leaves are the base of the pesto. From there, the ingredients are similar to what you would find in classic basil pesto. You can substitute with baby spinach.
  • Almonds are the nuts in this pesto, and I also stir chopped almonds into the barley and beans. You can substitute with walnuts.
  • Parmesan cheese: Just like the almonds, I include parmesan in the pesto and fold it into the final dish.
  • Garlic is a must-have pesto ingredient.
  • Scallions add mild green onion flavor to the overall dish. You can substitute with finely chopped red onions.
  • Lemon: The pesto calls for the juice of one lemon. Always use fresh juice and never bottled. 
  • Olive oil: Extra virgin olive oil has the best flavor.
  • Salt & pepper in the pesto season this barley recipe.

How To Make White Bean Barley with Arugula Pesto

1. Cook the barley. Combine the barley and water in a pot. Bring them to a boil, reduce heat and simmer until the grains are tender but chewy, about 12 minutes. Let stand for 2-3 minutes and fluff with a fork. Drain any excess water from the pot.

2. Combine the pesto ingredients in the bowl of a food processor or a blender. That includes the garlic, arugula, whole almonds, Parmesan, lemon juice, salt and pepper.

Serving

As mentioned, you can think of this as a vegetarian side or main. It would be great with grilled halloumi and vegetables, barbecue veggie tofu skewers or sheet pan baked feta.  Recipes with grains and vegetables are simple and satisfying. There are so many ways to approach them depending on the season. Arugula pesto goes with Mediterranean and Italian dishes that can include proteins such as chicken, salmon or shrimp. 

Leftovers & Storage

You can store leftovers in an airtight container in the fridge up to 3 days. Either warm them in the microwave or eat them cold. You can add more arugula or another type of leafy green to turn it into a salad with a splash of balsamic vinaigrette or lemon vinaigrette.

Make-Ahead Tips

You can make both the barley and pesto up to 2 days in advance. Store them in separate airtight containers in the refrigerator. Before you are ready to assemble the recipe, let the cooked barley and arugula pesto sit out at room temperature for 20 minutes, so they aren’t as cold.
