Ingredients You’ll Need
The beauty of this Onion Cottage Cheese Tart lies in its straightforward ingredients. Each component is essential, contributing layers of flavor, texture, and color that blend harmoniously in the final dish. From the tangy cottage cheese to the delicate pearl onions, every ingredient tells a part of the tart’s delicious story.
- 250 g cottage cheese: Provides a creamy, slightly tangy base that keeps the tart light yet rich.
- 50 g grated parmigiano: Adds a nutty, savory depth and a touch of saltiness to the filling.
- 1 egg: Binds the filling together for a smooth, custard-like texture when baked.
- 40 g pearl onions (3-4 onions): These small onions offer sweetness and subtle sharpness, beautifully mellowed by roasting.
- 1/3 tsp salt: Brings out the flavors of all the other ingredients without overpowering.
- 2 tbsp olive oil: Used to brush the onions, helping them caramelize and develop a luscious finish.
- Black pepper, to taste: Adds a gentle spiciness that enhances the dish’s complexity.
- 1 pie crust (store-bought or homemade): A buttery foundation that provides a flaky, golden base for the filling.
How to Make Onion Cottage Cheese Tart
Step 1: Prepare the Tart Crust
Start by lining your tart pan with the pie crust. Press it down gently, then prick the bottom and sides with a fork to prevent air pockets while baking. Pop it into a preheated oven at 200°C for about 10 minutes to pre-bake until it’s just starting to set but not browned. This step ensures a crisp crust that won’t get soggy once the filling is added.
Step 2: Mix the Filling
While the crust bakes, whisk the egg lightly in a bowl. Add the cottage cheese, grated parmigiano, and salt, stirring until everything is well combined. This mixture is the creamy heart of the tart, so mixing it thoroughly guarantees even texture and flavor.
Step 3: Prepare the Onions
Peel the pearl onions carefully and slice them lengthwise into thin, even pieces. Then, brush the exposed top side with olive oil. This little touch helps the onions develop a beautiful caramelized glaze while baking, enhancing their natural sweetness and aroma.
Step 4: Assemble the Tart
Take the pre-baked crust from the oven and spread the cottage cheese filling evenly across the base. Next, layer the prepared onion slices on top, making sure the oiled sides face upwards to catch the heat. Finish by sprinkling freshly cracked black pepper over the entire tart to add an inviting peppery kick.
Step 5: Bake to Perfection
Return the assembled tart to the oven and bake at 200°C for 30 to 35 minutes. Keep an eye out for a golden brown top with the filling set firm in the center. This baking time lets the flavors meld beautifully, while creating a luscious, melt-in-your-mouth texture you’ll adore.
How to Serve Onion Cottage Cheese Tart

Garnishes
Add a sprinkle of fresh thyme or finely chopped chives for a pop of color and herbaceous brightness. A light drizzle of extra virgin olive oil or a few flakes of sea salt right before serving can elevate the flavors spectacularly, making every bite feel special.
Side Dishes
This tart shines when paired with crisp, fresh greens like arugula or a simple mixed salad dressed lightly with lemon and olive oil. Roasted vegetables or a bowl of warm tomato soup also complement the rich cheesiness and sweet onions wonderfully.
Creative Ways to Present
Try serving the Onion Cottage Cheese Tart as individual mini tarts or tartlets for elegant entertaining. Alternatively, slice it into squares and serve warm or at room temperature on a rustic wooden board alongside artisanal bread and a glass of crisp white wine for a festive touch.
Make Ahead and Storage
Storing Leftovers
The Onion Cottage Cheese Tart keeps well in an airtight container in the refrigerator for up to three days. Simply cover the tart tightly with foil or plastic wrap to preserve moisture and freshness without losing the crispness of the crust.
Freezing
If you want to keep this tart longer, wrap it well with plastic wrap and foil, then freeze for up to two months. Defrost in the fridge overnight before reheating. Keep in mind, the crust may lose some crispness after freezing but the flavors remain wonderfully intact.
Reheating
Reheat slices gently in a preheated oven at 175°C for 10 to 15 minutes to restore warmth and bring back a little crunch in the crust. Avoid microwaving if possible, as it tends to make the crust soggy and the texture less enjoyable.
FAQs
Can I use regular onions instead of pearl onions?
Absolutely! While pearl onions provide a sweet and delicate flavor, thinly sliced regular onions can work well too. Just sauté them lightly beforehand to soften their sharpness for a similar effect.
Is it possible to make the tart crust from scratch?
Yes, a homemade tart crust can add a lovely personal touch. A simple butter-based pastry with flour and a pinch of salt works perfectly, and you can adjust the thickness to your liking for an extra flaky base.
Can I substitute parmigiano with another cheese?
Parmigiano offers a unique nutty flavor but you can swap it with pecorino, grana padano, or even a sharp cheddar for different flavor profiles. Just choose a cheese that melts well and complements cottage cheese.
How do I ensure the filling sets properly?
Whisking the egg well and pre-baking the crust are key steps. Baking at the recommended temperature and time allows the filling to firm up while remaining creamy without being runny.
Is this tart suitable for vegetarians?
Yes, the Onion Cottage Cheese Tart is vegetarian-friendly as it contains no meat products. Just be sure to use a vegetarian-friendly cheese if this is a concern, as some cheeses may contain animal rennet.
Final Thoughts
Making and sharing the Onion Cottage Cheese Tart is like passing along a little piece of culinary sunshine. It’s a wonderful dish that feels special but takes little effort, perfect for impressing friends or treating yourself. Once you experience the tender crust marrying the creamy cheese and sweet onions, I’m certain this tart will become one of your go-to recipes for any occasion.
