Marinated Zucchini Salad
This marinated zucchini salad is basically summer on a plate, and it’s about to become your new obsession for impressing people without breaking a sweat.

Picture paper-thin ribbons of zucchini and yellow squash soaking up a bright lemon vinaigrette that makes everything taste like it came from a fancy restaurant instead of your kitchen counter.

The magic happens when those vegetables sit in that tangy marinade for just 20 minutes, transforming from regular garden vegetables into something that tastes like you actually know what you’re doing in the kitchen.

Sweet corn kernels add little pops of sunshine, while crumbled feta brings that creamy, salty contrast that makes your taste buds do a happy dance.

Fresh herbs scattered throughout make every bite taste different, and those toasted walnuts add the perfect crunch that elevates this from “side salad” to “the star of the show.”

Best part? It gets better as it sits, which means you can make it ahead and watch people lose their minds over how fresh and vibrant everything tastes.

Ingredients
For the lemon vinaigrette
- Juice and zest of 1 lemon – freshly squeezed for maximum brightness
- 2 tablespoons apple cider vinegar – adds tangy depth
- 1 tablespoon honey – balances the acidity perfectly
- 2 tablespoons olive oil – extra virgin for best flavor
- 1 /2 teaspoon salt – enhances all the flavors
- 1 /4 teaspoon black pepper – freshly ground preferred
For the salad
- 2 large zucchinis – thinly sliced on a mandoline slicer
- 2 medium yellow squash – thinly sliced on a mandoline slicer
- 1 ear corn – kernels removed (about 3/4 cup)
- 1 /4 cup chopped fresh herbs – such as basil, chives, oregano and mint
- 1 /4 cup feta cheese – crumbled into bite-sized pieces
- 1 /4 cup walnuts – chopped and lightly toasted
- Sea salt – to taste for final seasoning
- Freshly ground black pepper – to taste
Instructions
Prepare the vinaigrette
- 1 In a large mixing bowl, whisk together the fresh lemon juice, lemon zest, 2 tablespoons apple cider vinegar, and 1 tablespoon honey until the honey is completely dissolved and the mixture is well combined. The honey should distribute evenly without any clumps remaining.
- 2 Slowly drizzle in the 2 tablespoons olive oil while whisking continuously to create a proper emulsion. Add 1/2 teaspoon salt and 1/4 teaspoon black pepper, whisking until the vinaigrette is smooth and well-blended.
Marinate the vegetables
- 3 Using a mandoline slicer set to the thinnest setting, carefully slice the 2 large zucchinis and 2 medium yellow squash into paper-thin ribbons. If you don’t have a mandoline slicer, use a sharp knife or vegetable peeler to create the thinnest slices possible – this ensures the vegetables absorb the marinade properly.
- 4 Add the zucchini and yellow squash ribbons to the bowl with the vinaigrette, tossing gently with clean hands or tongs to ensure every piece is coated. Cover the bowl and refrigerate for 20-30 minutes, allowing the vegetables to soften slightly and absorb the bright flavors of the marinade.
Finish and serve
- 5 While the vegetables are marinating, remove the corn kernels from the cob using a sharp knife, cutting close to the cob to get full kernels. Toast the 1/4 cup chopped walnuts in a dry skillet over medium heat for 2-3 minutes until fragrant and lightly golden.
- 6 Remove the marinated vegetables from the refrigerator and gently fold in the corn kernels, 1/4 cup chopped fresh herbs, toasted walnuts, and crumbled feta cheese. Taste and adjust seasoning with sea salt and freshly ground black pepper as needed before serving immediately.
