Charred Zucchini Salad With Lemon Basil Pistachio Oil tastes smoky, bright, nutty, and a little fancy without trying too hard. It works perfectly for weeknight dinners or casual cookouts and takes about 30 minutes from start to finish. I first made a version of this on a Tuesday when my fridge only held zucchini, herbs, and a questionable lemon, and it still tasted restaurant-level good.
Why Charred Zucchini Salad With Lemon Basil Pistachio Oil Is Worth It
Charred zucchini brings out a sweet, almost buttery flavor that plain sautéed zucchini never hits. The lemon basil pistachio oil adds citrusy freshness, herby perfume, and crunchy richness in every bite. You get a salad that feels light but still satisfies, with enough texture and flavor to stand on its own.
This recipe works well for meal prep, backyard grilling, or a quick side that looks impressive. You can serve it warm or at room temperature, so timing stays flexible when guests arrive late or kids move at kid speed. The whole thing uses simple ingredients that taste special when you treat them right.

Ingredients You Need
Zucchini and salad base
- 4 medium zucchini, firm and glossy
- 1 small red onion, very thinly sliced
- 1 cup cherry or grape tomatoes, halved
- 1 small handful fresh basil leaves, torn
- 1 small handful fresh parsley leaves, roughly chopped
- 1 teaspoon kosher salt, plus more to taste
- ½ teaspoon freshly ground black pepper
I like smaller zucchini because they stay tender and less watery. If you only have larger zucchini, scoop out some of the seedy center before slicing. Use any color tomato you like; mixed colors look pretty and taste slightly different, which adds interest.
Lemon basil pistachio oil
- ⅓ cup extra virgin olive oil
- ½ cup shelled roasted pistachios, unsalted or lightly salted
- Zest of 1 large lemon
- Juice of 1 large lemon (about 3 tablespoons)
- 1 packed cup fresh basil leaves
- 1 small garlic clove, minced or grated
- ½ teaspoon honey or maple syrup
- ¼ teaspoon red pepper flakes, or to taste
- ¼ teaspoon fine sea salt, plus more as needed
Use good olive oil here since it carries the flavor; California Olive Ranch or Kirkland organic both work nicely as pantry staples. If you only have salted pistachios, reduce added salt and taste as you go. Honey softens the acidity, but maple syrup keeps it vegan and tastes just as good.
Optional toppings
- Extra chopped pistachios for crunch
- Shaved Parmesan or pecorino
- Crumbled feta or goat cheese
- Extra basil or parsley leaves
You can skip cheese for a lighter or dairy free version. I like a mix of chopped pistachios and a small sprinkle of cheese for contrast. Keep toppings simple so the charred zucchini and lemon basil pistachio oil stay in the spotlight.
Equipment list
- Grill pan, cast iron skillet, or outdoor grill
- Large mixing bowl
- Small food processor or high speed blender
- Microplane or fine grater for lemon zest and garlic
- Tongs
- Cutting board and sharp knife
If you do not own a food processor, you can chop the basil and pistachios very finely and whisk the oil by hand. A grill pan on the stove gives nice char marks without firing up an outdoor grill. Cast iron works well because it holds heat and gives good color.
Quick Tips & substitutions
- Slice zucchini lengthwise into planks about ¼ inch thick so they char nicely without turning mushy.
- Pat zucchini dry before seasoning so the surface chars instead of steaming.
- Preheat your pan or grill until it feels very hot; high heat gives good color and flavor.
- Use avocado oil to cook the zucchini if you prefer an oil with a higher smoke point, then finish with olive oil in the dressing.
- Swap basil with a mix of basil and mint if you like a cooler, brighter flavor.
- Use almonds, walnuts, or sunflower seeds instead of pistachios if that is what you have.
- Replace honey with maple syrup or agave for a vegan version.
- Use yellow squash in place of some or all of the zucchini for more color.
- Add a can of drained chickpeas or white beans to turn this into a more filling main dish.
- Taste the lemon basil pistachio oil before you dress the salad and adjust salt, lemon, and sweetness so it hits your personal sweet spot.
How to Make Charred Zucchini Salad With Lemon Basil Pistachio Oil
Step 1: Prep the vegetables
Slice the zucchini lengthwise into long planks about ¼ inch thick. Lay them on a tray or cutting board and pat both sides dry with a clean towel. Sprinkle both sides with kosher salt and black pepper, then drizzle lightly with olive oil and rub to coat.
Thinly slice the red onion and place the slices in a bowl of cold water while you cook the zucchini. This quick soak takes away harsh bite and keeps the onion crisp. Halve the cherry tomatoes and set them aside in a large mixing bowl.
Step 2: Make the lemon basil pistachio oil
Add pistachios, basil leaves, lemon zest, lemon juice, garlic, honey or maple syrup, red pepper flakes, and salt to a small food processor. Pulse a few times to break everything down. Stream in the olive oil while you pulse until the mixture looks loose and spoonable, with small bits of pistachio still visible.
Taste and adjust with more salt, lemon juice, or honey as needed. The flavor should taste bright, slightly tangy, and nutty with a gentle kick from the red pepper flakes. If it feels too thick, add a splash of water or a bit more olive oil to loosen it.
Step 3: Char the zucchini
Heat a grill pan, cast iron skillet, or outdoor grill over medium high heat until very hot. Lay the zucchini planks in a single layer without crowding; they need space so they char instead of steaming. Cook each side for about 2 to 3 minutes until you see deep golden brown spots and the edges soften.
Flip with tongs and cook the second side for another 2 to 3 minutes. Taste one piece to check seasoning and texture; it should feel tender but not limp. Move finished zucchini to a plate and repeat with remaining slices, adding a tiny drizzle of oil to the pan if it looks dry.
Step 4: Build the salad
Drain the red onion slices and pat them dry. Add them to the large bowl with the tomatoes. Slice the warm charred zucchini planks into thick strips or bite sized pieces and add them to the bowl.
Spoon a few tablespoons of the lemon basil pistachio oil over the vegetables. Toss gently so you keep the zucchini pieces mostly intact. Add the torn basil and chopped parsley, then toss again and taste.
If the salad needs more brightness, add another spoonful of the pistachio oil or a squeeze of lemon. Adjust salt and pepper until every bite tastes seasoned and lively. You can serve the salad slightly warm or at room temperature.
Step 5: Finish and serve
Transfer the salad to a shallow serving platter. Drizzle a bit more lemon basil pistachio oil over the top so it looks glossy and inviting. Sprinkle with extra chopped pistachios for crunch.
Add shaved Parmesan, pecorino, or crumbled feta if you like cheese. Finish with a few extra basil or parsley leaves. Serve right away while the zucchini still holds a little warmth and the herbs smell fragrant.

Storage Success
Store leftover Charred Zucchini Salad With Lemon Basil Pistachio Oil in an airtight container in the fridge for up to 3 days. The zucchini softens a bit, but the flavors deepen and taste even more garlicky and lemony on day two. Keep extra lemon basil pistachio oil in a separate small jar in the fridge for up to 5 days and stir before using. If the oil firms up, let it sit at room temperature for 10 to 15 minutes and loosen it with a tiny splash of water or lemon juice.
