1-First Step: Preparation and Mise en Place Start by gathering all your ingredients to make the process smooth. Thinly slice the zucchini, yellow squash, new potato, and red onion using a mandoline for uniform pieces this helps them cook evenly and become flexible. For dietary tweaks, if you’re going vegan, have your silken tofu ready as a substitute. This step takes about 15 minutes and sets the stage for a great summer squash tart.

2-Second Step: Crust Preparation Now, focus on the crust: combine 1 cup of flour and 1/4 teaspoon of salt in a food processor, then pulse in 5 tablespoons of cold butter until it’s crumbly. Drizzle in 5 tablespoons of cold water while pulsing until the dough forms a lump don’t overmix! Shape it into a disk, wrap it, and refrigerate for at least one hour to ensure a flaky texture. If you’re using a gluten-free flour, mix it the same way but check for adaptations like adding xanthan gum.

3-Third Step: Slicing and Salting the Squash Once your dough is chilling, slice the vegetables thinly as mentioned. Lightly salt the zucchini and yellow squash slices to draw out excess moisture, letting them sit for about 10 minutes before patting them dry this prevents a soggy summer squash tart. For low-calorie versions, skip extra oil here and use a paper towel to absorb any liquid. This technique works great for vegan swaps too, keeping the filling light and fresh.

4-Fourth Step: Assembly of the Tart Roll out the chilled dough between parchment paper into a 12-inch circle, then spread 2 1/2 ounces of goat cheese evenly over it, leaving a border for folding. Layer the sliced vegetables and onion on top, seasoning with salt and pepper as you go. Drizzle with olive oil and brush the crust edges with melted butter if desired. For dairy-free needs, swap the cheese for a plant-based option and ensure even heat distribution by arranging veggies uniformly this step adapts easily to different preferences for your summer squash tart.

5-Fifth Step: Baking Instructions Bake the tart in your preheated 400°F (204°C) oven for 33 to 35 minutes, placing it on the middle rack for even cooking. Keep an eye on it; the crust should turn golden brown, and the veggies will become translucent. Test doneness by gently pressing the center it should feel set. This baking time works for most variations, including those with added proteins like ham for a heartier summer squash tart.

6-Sixth Step: Resting and Cooling Let the tart rest for about 10 minutes after baking to cool slightly, which makes slicing easier and lets flavors meld. If you want more color, pop it under the broiler for 1-2 minutes, but watch closely to avoid burning. This step is crucial for all dietary versions to retain texture and freshness in your summer squash tart.

7-Final Step: Finishing Touches and Serving Serve the tart hot or at room temperature, slicing it into 10 pieces for sharing. Add a simple garnish like fresh herbs if you like, and for reheating, use the oven to keep that crisp crust. This summer squash tart pairs great with a side like our grilled vegetables recipe, making it a complete meal for any occasion.
