Classic Three Bean Salad

A salad this simple has no business being so delicious, but it just is. This Classic Three Bean Salad has minimal ingredients, the most basic of basic dressings, and yet I can’t seem to get enough of it. The creamy beans are the perfect contrast to the tangy-sweet dressing, and there’s just enough savory crunch from the red onion to keep the flavors grounded. It’s the perfect summer side dish for all of your BBQs and potlucks, or on those busy weeknights when you don’t want to spend a lot of time fixing dinner.

What Beans Go In Three Bean Salad

My three bean salad has dark kidney beans, cannellini beans, and green beans. You can also try other beans like chickpeas, wax beans, purple hull peas, or black eyed peas.

Three bean salad is really flexible, so you can swap out the beans, and you can even add more than three beans if you’d like. The most important thing to remember when choosing your beans is that you want to have a variety of colors, textures, and shapes. Make sure to have at least one creamy bean, too.

What is the Dressing Like?

The dressing for this classic three bean salad is a very basic, slightly sweet vinaigrette with just enough Dijon to give it a little zing. If you don’t want to make your own dressing, you could potentially swap it out for something like a bottled Italian dressing, although that will have a different flavor.

What to Serve with Three Bean Salad

The sweet-tart flavor of this three bean salad makes it go perfectly with other sweet-savory flavors, like BBQ sauce. This week I served it with my BBQ Cheddar Baked Chicken and potato salad. It would also be a great side to something like Honey Mustard Wings, Brown Sugar Roasted Pork Loin, or BBQ Tofu Sliders.

How Long Does it Last?

Three bean salad is one of those recipes that actually gets better with time in the fridge. As it refrigerates the beans begin to absorb the flavors in the dressing and everything get SUPER tasty. This salad will probably stay good in the fridge for about four days (if you don’t eat it all by then).
