Roasted Zucchini With Lemon Herb Tahini

Last summer my neighbor dropped off a basket of garden zucchini that sat on my counter mocking me with its abundance. I'd been roasting zucchini for years, always the same way, until I decided to whisk together whatever was in my pantry and see what happened. That tahini sauce transformed everything—my husband actually asked if there was cheese in it. Now it's the first thing I make when summer vegetables start taking over my kitchen.

I made this for a dinner party where two guests were vegan and one was gluten-free, expecting to also grill chicken as backup. Everyone went back for seconds of the zucchini instead, and the platter looked absolutely gorgeous with that pale cream sauce against the golden rounds. My friend asked for the recipe before she even finished her first serving.

Ingredients

• 4 medium zucchinis: Look for ones that feel heavy for their size with firm, unblemished skin—thats how you know theyre fresh and will hold their shape when roasted
• 2 tbsp olive oil: This helps the zucchini caramelize instead of steam, so dont skip it or the texture wont be quite right
• 1/2 tsp sea salt: Table salt works too but sea salt gives a cleaner taste and you can actually use slightly less since it has more flavor
• 1/4 tsp black pepper: Freshly ground makes a noticeable difference here—pre-ground loses its punch pretty quickly
• 1/3 cup tahini: The natural oils separate so give it a really good stir before measuring, or youll end up with too much sesame paste
• 3 tbsp fresh lemon juice: Bottled lemon juice has this weird aftertaste, so please use fresh lemons for that bright, clean acid
• 2 tbsp cold water: Start with less and add more as needed—different tahini brands thicken differently
• 1 small garlic clove: Minced super fine so nobody bites into a raw garlic chunk, which happens more often than youd think
• 2 tbsp fresh parsley: Flat-leaf parsley has more flavor than curly, and it adds this fresh green note that cuts through the rich tahini
• 1 tbsp fresh dill: Dried dill works in a pinch but fresh dill makes the sauce taste brighter and more special
• 1/2 tsp ground cumin: Toast the cumin in a dry pan for 30 seconds before using—it unlocks this warm, nutty flavor
• 1/4 tsp salt: The tahini sauce needs its own seasoning since the tahini itself is pretty bland on its own
• 1/8 tsp cayenne pepper: Totally optional but just enough heat to make things interesting without overwhelming the other flavors
• 1 tbsp toasted sesame seeds: Toast them yourself in a small pan over medium heat—they become so much more fragrant

Instructions

Get your oven ready:

Preheat to 425°F and line a baking sheet with parchment—cleanup becomes so much easier and nothing sticks

Prep the zucchini:

Slice them into half-inch rounds and arrange on the sheet, then drizzle with olive oil and season with salt and pepper, using your hands to toss everything together

Roast until golden:

Bake for 20 to 25 minutes, flipping halfway through, until the bottoms are nicely browned and the zucchini feels tender when pierced

Make the magic sauce:

Whisk together the tahini, lemon juice, water, garlic, herbs, cumin, salt, and cayenne until smooth and creamy, adding more water if its too thick

Bring it all together:

Arrange the roasted zucchini on your serving platter and drizzle that tahini sauce all over it

Finish with flair:

Sprinkle toasted sesame seeds and any extra fresh herbs on top, then serve with lemon wedges on the side

My sister-in-law visited last month and claimed she hated zucchini, then ate three servings of this. She texted me the next day saying her husband was already asking when shed make it again. Sometimes the simplest ingredients surprise us in the best ways.

Making It Your Own

Once I made this with mint instead of dill because thats what I had, and it was completely different but equally delicious. The tahini sauce is incredibly forgiving—you can swap in whatever fresh herbs speak to you or even add a spoonful of yogurt for extra tang. I've also sprinkled smoked paprika over the zucchini before roasting when I wanted something with a bit more depth.

What To Serve With It

This works beautifully alongside grilled fish or chicken, but honestly I've eaten it as a main dish more times than I can count. The tahini makes it feel substantial enough that you dont necessarily need anything else. It's also perfect as part of a mezze spread with hummus, warm pita, and some olives—the flavors all play so nicely together.

Make Ahead Tips

The tahini sauce keeps in the fridge for at least a week and actually gets better as the flavors meld together. You can roast the zucchini ahead of time too, though it's best served warm or at room temperature rather than cold from the fridge.

• Store the sauce in a glass jar and give it a good stir before using since it thickens in the fridge
• If roasting zucchini ahead, reheat at 350°F for about 10 minutes to revive some of that texture
• The sauce thins out at room temperature, so adjust with water right before serving

Hope this becomes one of those go-to recipes you make without even thinking about it. There's something so satisfying about turning simple vegetables into something people cant stop eating.

Recipe FAQs

→ How do I know when the zucchini is done roasting?

The zucchini is ready when it's tender throughout and has developed golden-brown edges. This typically takes 20–25 minutes at 425°F. Flip the slices halfway through for even cooking.

→ Can I make the tahini sauce ahead of time?

Yes, the sauce keeps well in the refrigerator for up to 5 days. Store it in an airtight container. It may thicken when cold—simply whisk in a teaspoon of water to restore the creamy consistency.

→ What herbs work best in this sauce?

Fresh parsley and dill provide classic Mediterranean flavors, but you can substitute mint, cilantro, or basil based on preference. Use about 3 tablespoons total of fresh herbs for optimal flavor.

→ Is this dish suitable for meal prep?

Absolutely. Store roasted zucchini and sauce separately in the refrigerator for 3–4 days. Reheat the zucchini in a 350°F oven for 10 minutes, then drizzle with sauce before serving.

→ Can I grill the zucchini instead?

Yes, grilling adds a smoky dimension. Brush zucchini slices with olive oil and grill over medium-high heat for 3–4 minutes per side until charred and tender. The tahini sauce complements the grilled flavor beautifully.

→ How do I prevent the tahini sauce from separating?

Whisk the tahini vigorously with lemon juice first before adding water. This emulsion creates a stable base. If separation occurs, simply whisk again or add a teaspoon of warm water while stirring.
