Ingredients
Here’s what you’ll need to make this savory tart:
Onions: Sweet onions work best for this tart. Caramelizing them will bring out their natural sweetness and create that delicious, melt-in-your-mouth texture.
Cottage Cheese: The star of the filling! Cottage cheese adds a rich creaminess without being too heavy. It’s the perfect partner for the onions.
Eggs: These help bind the filling together and give it a custard-like texture.
Heavy Cream: Adds richness and smoothness to the filling. It helps balance the tanginess of the cottage cheese.
Parmesan Cheese: A little grated parmesan gives the tart an extra boost of umami flavor.
Butter: For sautéing the onions and greasing the tart pan. It adds richness to the filling and crust.
Flour: You’ll need some flour to make the crust—either regular all-purpose flour or whole wheat for a nuttier flavor.
Olive Oil: For cooking the onions, adding a bit of extra richness.
Salt and Pepper: To season the tart filling and crust to perfection.
Herbs: Fresh thyme or rosemary pair wonderfully with the onions and give the tart an aromatic flavor.

Instructions
Let’s get started and turn these simple ingredients into a delicious tart:
Make the Tart Crust: Start by making the crust. In a bowl, mix flour and a pinch of salt. Cut in cold butter until the mixture resembles coarse crumbs. Add a few tablespoons of cold water, one at a time, until the dough comes together. Press the dough into the base of a tart pan, and chill it in the fridge for 20 minutes to firm up.
Preheat the Oven: While the crust is chilling, preheat your oven to 375°F (190°C).
Caramelize the Onions: Heat olive oil and butter in a skillet over medium heat. Add the sliced onions and cook them slowly, stirring occasionally until they are golden brown and caramelized. This should take about 15-20 minutes. Season with salt, pepper, and fresh herbs like thyme or rosemary, and set aside to cool.
Prepare the Filling: In a bowl, combine cottage cheese, eggs, heavy cream, grated parmesan, salt, and pepper. Mix until smooth and well-combined. Fold in the caramelized onions and stir until evenly distributed.
Assemble the Tart: Take the chilled tart crust and spoon the onion and cottage cheese mixture into it, spreading it out evenly.
Bake the Tart: Place the tart in the preheated oven and bake for about 30-35 minutes, or until the filling is set and slightly golden on top. The crust should also be golden and crisp.
Cool and Serve: Let the tart cool for about 10 minutes before slicing. Serve warm or at room temperature for the best flavor.

Additional Tips
Here are some tips to get the most out of your Onion Cottage Cheese Tart:
Use a Tart Pan: A tart pan with a removable bottom makes it easy to remove the tart and serve it without the crust breaking.
Caramelize the Onions Slowly: Patience is key when caramelizing onions. Slow cooking them over medium heat allows the natural sugars to develop, creating that deep, sweet flavor.
Chill the Crust: Don’t skip the step of chilling the dough—it helps prevent shrinkage when baking.
Add Extra Herbs: Fresh herbs like thyme, rosemary, or even a bit of garlic can elevate the flavor of this tart. Feel free to experiment!
Freeze the Tart: This tart can be made ahead and frozen for up to 3 months. To bake from frozen, add about 10 extra minutes to the cooking time.
