Easy Classic Bean Salad for a Crowd
A big-batch, no-fuss bean salad that’s bright, tangy, and lightly sweet with a simple vinegar-and-olive-oil dressing. It holds well in the fridge, actually tastes better after a rest, and stays naturally gluten-free. Serve it as a cookout side, potluck dish, or make-ahead lunch prep. The texture is crisp-tender from celery and bell pepper, with herbs to freshen everything up.

Instructions
Mix
Drain and rinse all the beans well, then let them sit in the colander 5 minutes so they don’t water down the dressing.
In a very large bowl (or a clean stockpot), combine the beans, bell peppers, celery, red onion, and parsley.
Dress
In a bowl or large measuring cup, whisk together the vinegar, olive oil, sugar, Dijon, salt, pepper, and garlic until the sugar mostly dissolves and the dressing looks slightly thickened.
Pour the dressing over the bean mixture and toss thoroughly for 1–2 minutes, scraping the bottom, until everything is evenly coated.
Rest (makes it better)
Cover and refrigerate at least 2 hours (overnight is best). The flavors should taste brighter and more “marinated,” and the onions should soften.
Before serving, toss again and taste. If it needs a lift, add 1–2 Tbsp more vinegar. If it tastes too sharp, add 1–2 tsp more sugar. If it tastes flat, add a pinch more salt.
Tip: If you’re transporting this, keep it cold. It’s safe at room temp for serving, but don’t let it sit out longer than 2 hours (1 hour if it’s hot outside).
Notes
Make-ahead: Best after an overnight chill; keeps 4–5 days refrigerated. Onion note: If you want a milder onion bite, rinse the diced onion under cold water, drain well, then add. Variations: Add 1–2 cups halved cherry tomatoes right before serving; or swap parsley for dill. No Dijon? Use 2 Tbsp prepared yellow mustard.
