Step‑by‑Step Instructions for Summer Tomato Tart
Step 1: Caramelize Onions
In a large skillet, melt 2 tablespoons of butter over medium-low heat. Add 2 sliced onions, seasoning them with salt and pepper. Cook the onions slowly for about 20-25 minutes, stirring occasionally, until they become a beautiful golden brown and fragrant. This rich, caramelized goodness will lay the perfect foundation for your Summer Tomato Tart.
Step 2: Prep Cheese
While the onions are caramelizing, prepare the cheese for your tart. Grate ½ cup each of fontina, parmesan, and gruyère cheese, combining them in a bowl. Set this cheesy mixture aside, as it will add a delightful creamy texture and intense flavor to your tart.
Step 3: Roll Out Pie Crust
Preheat your oven to 450°F (232°C). If you’re using store-bought dough, roll it out gently on a floured surface until it reaches a uniform thickness. Fit the crust into a 9-inch tart pan, ensuring it covers the bottom and sides well. Prick the bottom with a fork to prevent bubbling while baking. This crust will cradle all the goodness of your Summer Tomato Tart.
Step 4: Assemble Tart
Once the onions are perfectly caramelized, start layering your tart. Spread a generous layer of the cheese mixture evenly over the chilled pie crust. Next, add the caramelized onions on top, followed by 1 ½ cups of whole cherry tomatoes, halved if you prefer a more vibrant look. This visually stunning assembly creates a base of rich flavors for your tart.
Step 5: Brush & Bake
In a small bowl, whisk together 1 egg and 2 tablespoons of milk until combined. Brush this mixture over the exposed crust of the tart, adding a beautiful shine when baked. Place the tart in your preheated oven and bake for about 25-30 minutes, or until the crust is golden brown and the cheese is bubbling. Enjoy the aroma filling your kitchen!
Step 6: Cool & Garnish
After baking, remove the Summer Tomato Tart from the oven and let it cool for about 5 minutes. This allows the cheese to set slightly. Finely slice fresh basil and sprinkle a generous amount over the tart for a fragrant finishing touch. Slice into wedges and serve warm, or let it cool completely for a delightful cold dish packed with summer flavors.

Summer Tomato Tart Recipe FAQs
How do I select the best tomatoes for my tart?
When choosing cherry tomatoes, look for plump, firm ones that are brightly colored and free from blemishes. The fragrance should be sweet and fresh, indicating ripeness. Avoid any with dark spots all over, as these may be overripe.
What’s the best way to store leftover Summer Tomato Tart?
To store the tart, place it in an airtight container in the refrigerator for up to 3 days. If reheating, pop individual slices back into the oven at 350°F for about 10-15 minutes to maintain its crispy crust.
Can I freeze the Summer Tomato Tart?
Absolutely! To freeze, let the tart cool completely, then wrap it tightly in plastic wrap followed by aluminum foil. You can keep it in the freezer for up to 3 months. When you’re ready to enjoy it, simply thaw it in the fridge overnight and reheat it in the oven.
What should I do if my onions start burning while caramelizing?
If your onions are browning too quickly, lower the heat and add a splash of water or broth to the pan. This will help to deglaze the skillet and prevent them from sticking or burning, allowing them to soften and caramelize properly over the next 20-25 minutes.
My tart crust is soggy; how can I prevent this?
To avoid a soggy crust, make sure to prick the bottom with a fork before baking. Additionally, pre-baking the crust for about 5 minutes before adding the filling can create a firmer base, helping to keep it crispy.
Is this Summer Tomato Tart suitable for vegans?
Definitely! To make it vegan, substitute the egg with a flax egg (1 tablespoon of flaxseed meal mixed with 2.5 tablespoons of water), and use plant-based dairy products instead of regular milk and cheese. There are plenty of great vegan cheese options available in stores that will work perfectly!
