Salads
This three bean salad recipe with wax beans delivers the perfect balance of textures and flavors—crisp wax beans, tender kidney beans, and buttery lima beans all tossed with fresh greens and a bright vinaigrette.
The secret to its staying power lies in the dressing, which keeps the beans vibrant and the greens crisp even after days in the fridge. I developed this recipe after realizing most store-bought versions rely on mayo, which turns soggy and dull within hours.
The beauty of this salad is its simplicity—just four types of beans, fresh herbs, and a quick lemon-herb dressing come together in 15 minutes of prep.
Unlike traditional versions, this one skips the heavy mayo in favor of a tangy vinaigrette that enhances the beans' natural sweetness while adding a refreshing crunch. The wax beans bring delicate crispness, while the kidney and lima beans add hearty texture and earthy depth.
What makes this salad truly special is how it evolves over time. The flavors meld beautifully after 24 hours, making it ideal for meal prep.
The dressing clings to the beans, keeping them moist without sacrificing freshness, while the greens stay crisp enough to cut through the rich bean flavors. Serve it chilled as a side dish, or pile it high on a sandwich for a satisfying vegetarian meal.
For best results, use canned beans (rinsed thoroughly) or pre-cooked dried beans to save time. The dressing should be made just before tossing to preserve its brightness, and adding fresh herbs at the last minute ensures maximum flavor. This salad is the ultimate make-ahead dish—easy to assemble, impossible to resist.
Ingredients for three bean salad recipe with wax beans
Four beans, fresh greens, and a tangy dressing—this salad is the ultimate make-ahead meal.
| Ingredient | Amount | Notes |
|---|---|---|
| Wax Beans 🥦 | 1 ½ cups | Trimmed, cut into 1-inch pieces |
| Kidney Beans 🌿 | 1 cup | Canned, drained and rinsed |
| Lima Beans 🌿 | 1 cup | Canned, drained and rinsed |
| Baby Spinach 🥬 | 4 cups | Fresh, loosely packed |
| Red Onion 🧅 | ¼ cup | Thinly sliced, about 1/4 cup |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | High quality, fruity |
| Lemon Juice 🍋 | 3 tbsp | Freshly squeezed |
| Dijon Mustard 🌶️ | 1 tbsp | Mild or regular |
| Fresh Parsley 🌿 | ¼ cup | Chopped, loosely packed |
| Fresh Dill 🌿 | 2 tbsp | Chopped, loosely packed |
| Salt 🧂 | ½ tsp | Sea salt preferred |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground |

Wax beans are the star here—their crisp texture holds up beautifully. Look for bright green, firm beans at the grocery store, preferably organic if you can find them. Whole Foods or local farmers markets often have the freshest wax beans, but even the regular produce section at Kroger or Safeway will do. The kidney and lima beans? Canned is totally fine—just drain and rinse them well. I always grab the no-salt-added versions to control the seasoning myself. Baby spinach is a must for that tender crunch, but arugula or mixed greens work too if that's what you've got.
No wax beans? Green beans or asparagus can step in, but they won't have that same delicate crunch. The dressing is where the magic happens—Dijon mustard adds depth, while the honey balances the lemon's acidity. Substitute maple syrup if you're avoiding honey. Fresh herbs are ideal, but dried parsley at one-third the amount works in a pinch. The red onion adds a sharp bite, but if you're sensitive to raw onions, cook them down first to mellow the flavor. For extra protein, toss in some chickpeas or white beans—they blend right in.
This salad tastes even better the next day, so make it ahead and store it in an airtight container. Keeps for 4-5 days in the fridge, and the dressing keeps the greens crisp. I always double the batch—one for lunch, one for dinner. The wax beans stay crunchy if you keep them separate until just before serving. For a heartier meal, pile it high on toasted bread with a sprinkle of vegan cheese. Trust me, it's a game-changer for sandwiches too.

Step-by-step instructions for three bean salad with wax beans
Here's how to build a vibrant, crunchy salad that keeps its texture for days.
Prepare the Bean Base
Start by rinsing the 1 cup kidney beans and 1 cup lima beans under cold water to remove any canned residue. Drain them thoroughly in a colander and transfer to a large mixing bowl. Add the 1.5 cups wax beans (already trimmed and cut into 1-inch pieces) and toss everything together gently.
I like to give them a quick massage with my hands to break up any clumps—this ensures even distribution later. The wax beans will add that delightful crunch, while the kidney and lima beans provide hearty texture. Don't skip rinsing the canned beans, even if they look clean—it removes that metallic taste that can ruin the fresh flavor.
Add Spinach and Onion
Gently fold in the 4 cups baby spinach and 0.25 cup thinly sliced red onion using a large spoon or your hands. The spinach should wilt slightly from the contact with the beans, but that's okay—it'll perk right back up when we add the dressing. Distribute the onion evenly throughout the mixture.
Here's the thing—don't overmix. We want those ingredients to stay in their own pockets for visual appeal and texture contrast. The spinach should look like it's nestled among the beans rather than completely blended in. This is where the salad gets its beautiful layered look that makes it so inviting.
Whisk Together the Dressing
In a small bowl, whisk together the 0.25 cup extra-virgin olive oil, 3 tbsp lemon juice, 1 tbsp Dijon mustard, 1 tbsp honey, 0.5 tsp salt, and 0.25 tsp black pepper until fully combined. The dressing should look emulsified—smooth with no visible oil separation. If it does separate, whisk a bit longer or add a splash of water to help it come together.
Taste a small spoonful of the dressing before adding it to the salad. You might find it needs a touch more salt or lemon—adjust to your preference. The honey helps balance the acidity from the lemon while adding subtle sweetness that complements the beans beautifully. This is your flavor foundation, so don't rush this step.
Combine Everything
Pour the dressing over the bean mixture and toss gently but thoroughly to coat all ingredients evenly. Add the 0.25 cup chopped fresh parsley and 2 tbsp chopped fresh dill, then toss again. The herbs should be distributed throughout rather than clumped in one area—this ensures every bite has that fresh, herby brightness.
Let the salad sit for 10-15 minutes at room temperature before serving. This gives the flavors time to meld together and the dressing to fully penetrate the ingredients. If you're making this ahead, this resting time is especially important—it helps the salad develop its full flavor profile.
Chill and Serve
Transfer the salad to an airtight container and refrigerate for at least 1 hour before serving. The chilling time allows the flavors to really come together and the textures to settle. When you're ready to serve, give it one final gentle toss to redistribute any ingredients that may have separated during chilling.
This salad keeps beautifully in the refrigerator for up to 5 days. The wax beans maintain their crunch, the spinach stays vibrant, and the dressing doesn't separate. Serve it as a side dish, stuff it into sandwiches, or enjoy it as a light main course with some crusty bread. The contrast of textures and flavors makes every bite satisfying and refreshing.
Pro Tips For Making Three Bean Salad Recipe With Wax Beans
- DRESS BEANS IMMEDIATELY: Wax beans and spinach wilt into sad mush if you toss them in dressing too early. Wait until all beans are cooled—about 20 minutes after draining—and only add dressing right before serving. This keeps the wax beans crisp and the spinach bright, not soggy. (Yes, even if you’re impatient like me.)
- TRIM WAX BEANS LIKE A PRO: Skip the messy snipping—just snap off the ends by hand where they naturally break. This is faster, cleaner, and leaves the beans looking uniform. For wax beans with tough strings, give them a quick rub with a kitchen towel before trimming to make the job easier.
- SOAK KIDNEY BEANS OVERNIGHT: I used to skip soaking and wonder why my kidney beans stayed mealy. Soak them in cold water for 8–12 hours, then drain and rinse before cooking. This cuts down on cooking time and guarantees they’ll hold their shape in the salad, not turn to mush when mixed with the dressing.
- SAUTE ONIONS LOW AND SLOW: Red onions caramelize best at a steady simmer—not a fast sear. Cook them in a little olive oil over medium-low heat for 8–10 minutes until soft and golden, stirring occasionally. This adds depth to the salad without burning them, and it’s the difference between bland and actually flavorful.

Frequently asked questions
Can I substitute wax beans with another vegetable?
Yes! If you can't find wax beans, try green beans or asparagus for a similar crunch. For extra tenderness, use sugar snap peas or shredded carrots. Just keep in mind that wax beans' delicate crispness is unique—other veggies may alter the texture slightly.
How do I keep the wax beans from getting soggy?
Store the wax beans separately in the fridge until just before serving to maintain their crunch. When ready, toss them with the other ingredients right before eating. The lemon dressing also helps preserve crispness—its acidity prevents wilting better than mayo-based dressings.
Can I make this salad ahead of time?
This salad tastes even better after 24 hours as flavors meld together. Store in an airtight container for up to 5 days. Keep the wax beans separate until serving to preserve their texture. The dressing will help maintain freshness longer than traditional mayo-based versions.
What if I don't have fresh herbs?
No problem! Use dried parsley (one-third the amount) or dried dill. For extra flavor, add 1 tsp dried basil or oregano. Fresh herbs brighten the salad, but dried versions work well in a pinch. The lemon dressing will still provide plenty of zing.
Is this salad gluten-free?
Yes, this recipe is naturally gluten-free! All ingredients are gluten-free by default. Just double-check your canned beans for potential cross-contamination warnings if you're highly sensitive. The dressing ingredients are all gluten-free as well. Perfect for gluten-free diets!
