Why I Love This Recipe

The first time I made this was during a really hot summer week when turning on the oven felt like a terrible idea. I had pasta, cucumbers, and some vegan mayo sitting in the fridge. I tossed everything together, added dill and lemon, and hoped for the best.

It turned out way better than expected. The cucumbers stayed crisp, the dressing was creamy but light, and the lemon gave it a bright flavor that made the whole dish pop.

Now it’s one of those recipes I go back to again and again because it’s:

• Fresh and cooling
• Super quick to make
• Perfect for meal prep
• Great for BBQs and potlucks
• Creamy without any dairy

It’s simple food, but it really hits the spot.

What You’ll Need

• 12 oz rotini pasta
• 2 cups cucumber, diced
• 1/3 cup red onion, thinly sliced
• 1/3 cup vegan mayonnaise
• 1 tablespoon lemon juice
• 1 tablespoon fresh dill, chopped
• 1/2 teaspoon garlic powder
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper

Tools Required

• Large pot
• Colander
• Cutting board
• Sharp knife
• Large mixing bowl
• Small mixing bowl
• Measuring cups
• Measuring spoons
• Spoon or spatula

Recipe Instructions

Step 1: Cook the Pasta

Bring a large pot of water to a boil. Add 12 oz rotini pasta and cook according to the package directions (usually about 9–10 minutes) until tender. Drain the pasta in a colander and rinse with cold water to stop the cooking. Let it drain well so the salad doesn’t get watery.

Step 2: Prep the Vegetables

While the pasta cooks, dice 2 cups cucumber, thinly slice 1/3 cup red onion, and chop 1 tablespoon fresh dill.

Step 3: Make the Dressing

In a small bowl, combine 1/3 cup vegan mayonnaise, 1 tablespoon lemon juice, 1/2 teaspoon garlic powder, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Stir until smooth and creamy.

Step 4: Combine the Salad

In a large bowl, add cooled rotini pasta, 2 cups diced cucumber, 1/3 cup sliced red onion, and 1 tablespoon chopped dill.

Pour the dressing over everything and toss well so the pasta is fully coated.

Step 5: Chill and Serve

Let the pasta salad chill in the fridge for at least 15 minutes so the flavors blend. Give it a quick stir and serve in a round bowl.

Pro Tips

• Cool the pasta fully. Warm pasta can thin the dressing and make the salad watery.
• Salt the pasta water well. This is the main chance to season the pasta itself.
• Use firm cucumbers. Soft cucumbers release more water.
• Chill before serving. The flavor gets much better after resting for 15–30 minutes.

Substitutions and Variations

• Swap rotini for bowtie, penne, or shells
• Add chickpeas for extra protein
• Add cherry tomatoes for color and sweetness
• Replace dill with parsley if you prefer
• Use vegan Greek yogurt instead of mayo for a tangy dressing

Make Ahead Tips

This salad actually tastes better after sitting for a while.

Make it up to 24 hours ahead and store it in the fridge. If it thickens too much, stir in 1–2 tablespoons of plant milk or lemon juice before serving.

Why This Recipe Works (Quick Science)

Pasta salads work best when the starch in the pasta cools down. As pasta cools, the starch firms up slightly, helping it hold onto dressing instead of absorbing it too quickly.

The lemon juice adds acidity, which balances the richness of the vegan mayo. Meanwhile, cucumbers add water and crunch, keeping the dish fresh and light.

That combo—fat, acid, and crunch—is what makes every bite satisfying.

Common Mistakes

Using warm pasta
Warm pasta melts the dressing and makes the salad watery.

Not draining cucumbers well
Extra water can dilute the dressing.

Not seasoning enough
Pasta needs enough salt or it can taste bland.

Skipping the chill time
The flavor improves a lot after resting.
