Zucchini Ricotta Tart with Lemon Herbs and Crispy Crust

Zucchini Ricotta Tart with Lemon Herbs

A wet, doughy bottom kills the whole experience of a savory tart. Most people just slice the zucchini and toss it on top, but that's a mistake because zucchini is mostly water. As it bakes, that moisture leaks into the ricotta and the dough, leaving you with a mushy mess instead of a crisp bite.

This recipe fixes that with a simple salting step. By drawing the water out first, you get a tart where the crust stays flaky and the filling stays light. It's a bright, fresh dish that tastes like a garden in the middle of July.

You'll get a contrast of textures here. The buttery base supports a silky lemon ricotta cream, topped with tender, slightly charred zucchini ribbons. It's simple, budget-friendly, and doesn't require fancy equipment.

The Trick to Dry Veggies

• Osmosis at Work: Salting the zucchini eliminates excess moisture. This stops the filling from becoming watery while in the oven.
• Fat and Acid Balance: Lemon juice and zest brighten the rich flavors of the butter and ricotta. This keeps the taste profile fresh rather than overly heavy.
• Temperature Control: Keeping the dough cold prevents the butter from melting too soon. This generates the steam pockets that give the crust its flakiness.

What Each Ingredient Does

The Shopping List

• 1½ cups (190g) all-purpose flour
• ½ cup (115g) cold unsalted butter, cubed Why this? Cold fat is what makes the crust flaky.
• ½ tsp (3g) salt
• 4 tbsp (60ml) ice cold water
• 15 oz (425g) whole milk ricotta cheese, drained Why this? Whole milk version is richer and holds its shape.
• 1 tbsp (15ml) lemon juice
• 1 tbsp (6g) lemon zest, finely grated
• 2 tbsp (8g) fresh thyme leaves, chopped
• ¼ tsp (1.5g) black pepper
• ¼ tsp (1.5g) salt
• 2 medium (450g) zucchini Why this? Medium ones have fewer seeds and less water.
• 2 tbsp (30ml) extra-virgin olive oil
• 1 tsp (5g) flaky sea salt
• 1 tbsp (3g) fresh parsley, chopped

Necessary Gear

You'll need a 9 inch tart pan, ideally one with a removable bottom so you can slice it easily. A food processor makes the crust quickly, but a pastry cutter works too. A mandoline or a vegetable peeler is the best way to get those thin zucchini ribbons.

Step-by-step Assembly

Drawing Out Excess Moisture

Use a peeler or mandoline to create thin, long ribbons of zucchini. Toss them in a bowl with 1 tsp (5g) of flaky sea salt and let them rest for 30 minutes to purge extra liquid. This step is necessary given the high water content of zucchini, as documented by USDA FoodData Central. Use paper towels to pat the ribbons thoroughly dry until they are tacky to the touch.

Making the Buttery Base

In a food processor, pulse 1½ cups (190g) all-purpose flour and ½ tsp (3g) salt. Add ½ cup (115g) of cold, cubed butter and pulse until the mixture reaches a coarse crumb consistency. Slowly stir in 4 tbsp (60ml) ice-cold water until the dough just begins to clump together.

Press the dough evenly into the bottom and sides of a 9-inch tart pan. Prick the base with a fork and refrigerate for 15 minutes.

Filling and Baking

In a medium bowl, combine 15 oz (425g) drained ricotta, 1 tbsp (15ml) lemon juice, 1 tbsp (6g) lemon zest, 2 tbsp (8g) chopped thyme, ¼ tsp (1.5g) salt, and ¼ tsp (1.5g) black pepper, folding until smooth.

Spread the ricotta mixture evenly over the chilled dough, leaving a 0.5-inch border. Arrange the dried zucchini ribbons on top in an overlapping fan pattern. Finish with a drizzle of 2 tbsp (30ml) extra-virgin olive oil and a pinch of black pepper.

Heat your oven to 375°F (190°C). Bake for 25 minutes until the crust edges are deep golden and the zucchini is tender. Garnish with 1 tbsp (3g) chopped fresh parsley immediately after removing from the oven.

Fixing Common Issues

If your crust feels soft, you likely skipped the salting step or didn't pat the zucchini dry enough. This is the most common reason for a soggy base. Make sure the ribbons feel tacky, not wet.

If the edges are browning too fast but the center is still pale, you can cover the rim with a strip of foil for the last 10 minutes. This protects the pastry from burning while the middle finishes.

Troubleshooting Guide

Fresh Flavor Twists

For a different profile, try Pesto Infused Ricotta by stirring 2 tbsp of basil pesto into the ricotta mixture before spreading it on the crust. This adds a bold hit of garlic and parmesan that complements the lemon.

For another way to enjoy your summer produce, a classic zucchini bread serves as a wonderful sweet contrast to this savory meal.

Storage and Leftovers

Store any leftovers in a covered glass dish in the refrigerator for a maximum of 3 days.

Skip the microwave for reheating to keep the crust from turning rubbery. To restore that crisp texture, heat a slice in an air fryer or oven at 350°F (175°C) for 5 minutes. Freezing is not advised, as the zucchini and ricotta weep water when thawed, ruining the consistency.

To avoid waste, keep your zucchini ends and grate them into a frittata or stir-fry.

Making It Look Great

The visual appeal of this dish is all in the zucchini placement. Instead of piling them on, lay them in a tight spiral or a fan pattern.

I like to serve this with a side of arugula tossed in a simple lemon vinaigrette. The bitterness of the greens balances the richness of the cheese. Slice the tart into 6 equal wedges using a serrated knife to avoid crushing the delicate crust.
