Light and gorgeous, this Egg Zucchini Noodle Salad is a perfect quick salad. Made with just a few fresh ingredients and dressed in a tangy mustard and flaxseed oil vinaigrette, it’s a flavorful way to enjoy raw spiralized zucchini all season long.

I used to fill my cabinets with kitchen gadgets—mixers, waffle makers and more—until I realized I wasn’t using most of them. When I moved, I decided to keep only what I use daily. One small exception was an electric spiralizer, and it turned out to be the best kitchen investment I ever made. It produces fresh vegetable noodles in seconds and inspired my love of zucchini noodles.
Zucchini noodles are easy to make, refreshing, and a healthy substitute for pasta. They’re the base of this Egg Zucchini Noodle Salad—simple, colorful, and satisfying. It’s a great option for a quick lunch, a light dinner side, or a dish to take to potlucks and picnics. Below you’ll find the ingredients, an easy method, and a few tips to make this salad shine.

Egg Zucchini Noodle Salad Ingredients
Simple, fresh ingredients make this salad bright and nutritious. You’ll need:
- Hard-boiled eggs: Whole eggs add protein and satiety. Use free-range or organic eggs if possible.
- Zucchini: One medium zucchini spiralized into noodles. Keep the skin for texture and nutrients.
- Cherry tomatoes: A handful, halved, for sweetness and color.
For the mustard flaxseed oil vinaigrette:
- Flaxseed oil: Cold-pressed flaxseed oil lends omega-3s and a rich, nutty flavor. If you prefer, extra virgin olive oil can also be used.
- Dijon mustard: Adds tang and balances the oil.
- Apple cider vinegar: Brightens the dressing.
- Water: A tablespoon to thin the dressing slightly.
- Dill: Fresh or dried, it pairs beautifully with eggs and the vinaigrette.
- Red pepper flakes: Optional, for a touch of heat.
- Lemon juice and salt: To finish and adjust seasoning.
Dill and red pepper flakes elevate the flavors, while a squeeze of lemon brightens the whole salad.

How to make Egg Zucchini Noodle Salad
- Make the zucchini noodles. Wash and dry one medium zucchini, trim the ends, and spiralize it. Leave the skin on for structure and nutrients.
- Hard-boil the egg. Place one cold egg in boiling water and cook for 8–10 minutes. Cool in cold water, peel, and chop.
- Prepare the tomatoes. Wash and halve a handful of cherry tomatoes.
- Make the vinaigrette. In a small jar or bowl, combine 2 tablespoons cold-pressed flaxseed oil (or extra virgin olive oil), 2 tablespoons apple cider vinegar, 1 tablespoon water, 1 teaspoon Dijon mustard, a pinch of salt, and a pinch of dill. Close and shake or whisk until emulsified. Taste and adjust seasoning. Add a pinch of red pepper flakes if you like a little heat.
- Assemble the salad. In a salad bowl, combine the zucchini noodles, chopped hard-boiled egg, and halved tomatoes. Pour the vinaigrette over the salad and gently toss to coat. Finish with a squeeze of lemon and more salt if needed. Sprinkle fresh dill on top.
- Serve. Serve immediately at room temperature, or refrigerate for a chilled salad.
Useful tips:
- Store leftovers in an air-tight container in the refrigerator for up to 3 days. A little lemon juice helps keep ingredients fresh.
- Make extra vinaigrette and keep it refrigerated in a sealed jar for up to two weeks. Shake before using.
- If you don’t have a spiralizer, thinly slice the zucchini with a peeler to create ribbons instead.

This Egg Zucchini Noodle Salad is an easy, nutrient-packed way to enjoy fresh zucchini. The combination of high-quality protein from the egg, heart-healthy oils in the dressing, and vibrant vegetables makes it a balanced and satisfying meal. It’s flexible, fast to put together, and perfect any time you want a light but filling dish.
