Introduction
These Summer Squash Sheet-Pan Tacos are a fresh and flavorful way to enjoy seasonal vegetables. Roasted squash and zucchini are paired with tangy pickled shallots and a creamy tahini sauce, all wrapped in warm corn tortillas. Perfect for a quick, satisfying meal.

Ingredients
- 2 medium yellow squash, cut into 1/2″ pieces (5 to 6 cups)
- 2 medium zucchini, cut into 1/2″ pieces (5 to 6 cups)
- 2 tablespoons extra-virgin olive oil
- Kosher salt
- 3 small shallots, very thinly sliced
- 1 cup red wine vinegar
- 2 tablespoons granulated sugar
- 1/2 teaspoon za’atar
- 1/4 cup tahini
- 2 tablespoons chopped fresh parsley
- 2 tablespoons fresh lime juice
- 1 teaspoon smoked paprika
- 1/2 teaspoon granulated garlic
- 8 (6″) corn tortillas
- 1/2 cup homemade or store-bought hummus
Instructions
- Step 1: Preheat the oven to 450°F (230°C). On a baking sheet, toss the yellow squash and zucchini with olive oil and season with kosher salt. Roast the vegetables, stirring halfway through, until softened and beginning to caramelize, about 25 to 30 minutes.
- Step 2: While the squash roasts, place the thinly sliced shallots in a small heatproof bowl. In a small saucepan over medium heat, combine the red wine vinegar, sugar, za’atar, and a pinch of salt. Warm the mixture until it is hot and steam rises, but do not let it simmer. Pour this hot liquid over the shallots and let them sit for 10 to 15 minutes to pickle gently.
- Step 3: In a medium bowl, whisk together tahini, chopped parsley, fresh lime juice, smoked paprika, granulated garlic, and salt. Gradually add 4 to 5 tablespoons of cold water until the sauce is thin and smooth.
- Step 4: During the last 5 minutes of roasting the squash, place the corn tortillas on a separate sheet tray or wrap them in foil. Bake until warmed through and pliable.
- Step 5: To assemble the tacos, spread about 1 tablespoon of hummus in the center of each tortilla. Top with the roasted squash and zucchini, then add the pickled shallots. Drizzle with the tahini sauce and serve immediately.
Tips & Variations
- For added heat, sprinkle chopped fresh chili or a dash of hot sauce over the tacos.
- Swap za’atar with cumin or smoked paprika for a different flavor profile.
- Use flour tortillas if you prefer a softer texture.
- Add crumbled feta or cotija cheese for extra richness.
- If you don’t have tahini, plain Greek yogurt can be a creamy substitute in the sauce.
Storage
Store leftover roasted squash and pickled shallots separately in airtight containers in the refrigerator for up to 3 days. The tahini sauce can also be refrigerated for up to 2 days. Reheat the squash in a skillet or oven before assembling tacos again. Tortillas are best warmed fresh but can be wrapped in foil and gently reheated.

- 2 tbsp. extra-virgin olive oil
- Kosher salt, to taste

- 1 cup red wine vinegar
- 2 tbsp. granulated sugar
- 1/2 tsp. za’atar
Tahini Sauce
- 1/4 cup tahini
- 2 tbsp. chopped fresh parsley
- 2 tbsp. fresh lime juice
- 1 tsp. smoked paprika
- 1/2 tsp. granulated garlic
- Kosher salt, to taste
- 4 to 5 tbsp. cold water
Assembly
- 8 (6″) corn tortillas
- 1/2 cup homemade or store-bought hummus
Instructions
- Preheat and Roast Squash: Preheat your oven to 450°F. On a baking sheet, toss the cut yellow squash and zucchini with extra-virgin olive oil and season generously with kosher salt. Roast the vegetables, stirring once halfway through, until they are softened and beginning to caramelize, about 25 to 30 minutes.
- Pickle Shallots: While the squash roasts, place the thinly sliced shallots in a small heatproof bowl. In a small saucepan over medium heat, combine the red wine vinegar, granulated sugar, za’atar, and a pinch of kosher salt. Warm the mixture just until it is hot and steaming, but not simmering. Pour this pickling liquid over the shallots and let them sit for 10 to 15 minutes to develop flavor.
- Make Tahini Sauce: In a medium bowl, whisk together the tahini, chopped fresh parsley, fresh lime juice, smoked paprika, granulated garlic, and kosher salt. Gradually whisk in 4 to 5 tablespoons of cold water until the sauce reaches a thin, smooth, and pourable consistency.
- Warm Tortillas: During the last 5 minutes of the vegetable roasting time, place the corn tortillas on a separate sheet tray or wrap them in foil and bake in the oven until warmed through and pliable.
- Assemble Tacos: Spread about 1 tablespoon of hummus in the center of each warm tortilla. Top with a generous portion of the roasted squash and zucchini, followed by a spoonful of the pickled shallots. Drizzle the prepared tahini sauce over the tacos before serving.
Notes
- You can prepare the pickled shallots ahead of time for a more intense flavor.
- For a spicier kick, add a sprinkle of chili flakes or hot sauce to the tahini sauce.
- Leftover roasted vegetables and sauce can be refrigerated and enjoyed for several days.
- Use gluten-free tortillas if you need to keep this recipe gluten-free.
