Leek Burrata Triangoli Lemon Butter

The afternoon I burned through an entire batch of breadcrumbs learning this dish, my kitchen smelled like Campari and regret, but those sad little triangles of pasta got me hooked on something I still crave on rainy Tuesdays. There is a quiet kind of magic in folding dough around burrata and watching it disappear into something elegant. Leek Burrata Triangoli with Lemon Butter Breadcrumbs is one of those recipes that rewards your patience with every silky, crunchy bite.

I made a double batch of these triangoli for my neighbors last spring when their newborn finally started sleeping through the night, and we stood around the kitchen island eating them off paper plates because nobody had the energy for real dishes. They barely lasted ten minutes.

Ingredients

• 00 flour (250 g plus extra for dusting): This finely milled Italian flour creates a silkier dough than all purpose, and the difference is noticeable when you roll it thin enough to see your hand through.
• 2 large eggs: Room temperature eggs incorporate more smoothly into the flour, saving your arms a few minutes of kneading.
• Olive oil (1 tbsp): Just a small splash in the dough keeps it pliable and easier to roll without springing back.
• Salt (pinch for dough, to taste for filling): Even a pinch in the pasta dough sharpens the flavor considerably compared to leaving it out.
• Leeks (2 medium, white and light green parts): Slice them thin and wash thoroughly, because grit hiding between the layers is the fastest way to ruin a delicate filling.
• Burrata (200 g, well drained): Drain it on paper towels for at least fifteen minutes or the filling turns wet and slips right out of your triangles.
• Unsalted butter (2 tbsp for leeks, 2 tbsp for breadcrumbs, 60 g for sauce): Three separate applications, each one doing something completely different for the final dish.
• Lemon zest (zest of 1/2 lemon for filling, zest of 1 whole lemon for breadcrumbs, zest of 1/2 lemon for sauce): Use a microplane and zest only the bright yellow layer, because the white pith underneath will make everything bitter.
• Sourdough breadcrumbs (50 g, fresh): Tear real sourdough into pieces and pulse in a food processor for crumbs that actually taste like something when they toast.
• Fresh parsley (1 tbsp, finely chopped): Flat leaf parsley adds a clean, grassy note that ties the breadcrumbs to the rest of the dish.
• Lemon juice (from 1/2 lemon): Fresh only, since the bottled stuff tastes flat and metallic next to real butter.
• Freshly cracked black pepper: Crack it coarse and generous, especially in the sauce where it becomes a noticeable flavor rather than background seasoning.

Instructions

Build the Dough:

Mound the flour on your cleanest counter and carve a deep well in the center like a tiny volcano, then drop in the eggs, olive oil, and salt before gently beating the wet ingredients with a fork and slowly pulling in flour from the walls. Knead the shaggy mass for eight to ten minutes until it feels smooth and springs back when you press it with your thumb, then wrap it tightly in plastic and let it nap for thirty minutes.

Cook Down the Leeks:

Melt two tablespoons of butter in a wide pan over medium heat and add the chopped leeks, stirring occasionally for six to eight minutes until they collapse into soft, sweet ribbons without taking on any color. Let them cool completely before folding in the drained burrata, lemon zest, salt, and pepper so the cheese stays creamy rather than melting into a puddle.

Roll and Shape the Triangoli:

Halve the rested dough and roll each portion through a pasta machine or with a rolling pin until you can almost see your fingers through it, then cut into roughly eight centimeter squares. Spoon a teaspoon of filling into the center of each square, fold corner to corner into a triangle, and press the edges firmly with damp fingers to seal, arranging them on a generously floured tray as you go.

Toast the Breadcrumbs:

Melt two tablespoons of butter in a skillet over medium heat, scatter in the sourdough crumbs, and stir almost constantly for three to four minutes until they turn a deep even gold and smell like a bakery at dawn. Kill the heat and fold in the lemon zest, parsley, and a pinch of salt, then set aside in the pan so they stay crunchy.

Cook and Sauce the Pasta:

Slide the triangoli into a large pot of gently boiling salted water and cook for three to four minutes until they float and the edges feel tender but still have a slight bite, while simultaneously melting the remaining butter in a large skillet with lemon juice, zest, and pepper. Transfer the pasta directly from the water into the bubbling sauce with a slotted spoon and toss gently so each triangle gets glossed, then plate and shower with those golden breadcrumbs before serving.

Save

Somewhere between the second and third time I made these, I stopped measuring the breadcrumbs and started toasting them by sound and smell alone, which is when I knew the recipe had genuinely become mine.

Getting the Pasta Dough Right

The dough should feel like the soft heel of your hand when it is properly kneaded, supple and just barely tacky without sticking to the surface. If it feels dry and reluctant, wet your palms slightly during kneading rather than adding more oil, which can make the final texture dense. Humidity plays a bigger role than most recipes acknowledge, so trust your fingers over the clock when deciding if the dough needs more or less resting time.

Choosing and Prepping Leeks

Leeks are sneaky vegetables that trap soil in every layer, so slice them first and then soak the rounds in a bowl of cold water, lifting them out with your hands and leaving the grit behind. Only the white and pale green portions belong in this filling because the darker greens are fibrous and will create tough strings through the creamy burrata. Cook them low and patient, since browning introduces a nutty flavor that clashes with the gentle sweetness you want here.

Serving and Pairing Suggestions

These triangoli are best eaten immediately while the contrast between the silky sauce and the crunchy breadcrumbs is at its peak, so have everything else on the table ready before you start plating. A chilled glass of Pinot Grigio or a crisp Vermentino alongside turns a weeknight dinner into something that feels deliberately special.

• Scatter a few chili flakes into the breadcrumbs if you want a subtle heat that plays beautifully against the rich butter.
• A light arugula salad with lemon vinaigrette on the side gives the meal a fresh, peppery counterpoint.
• Call people to the table before you drop the pasta, because waiting even five minutes softens those breadcrumbs you worked so hard to crisp.

Save

There is a particular kind of happiness that comes from watching someone bite into food you folded by hand, and these little triangles deliver that feeling every single time. Make them once and you will find yourself looking for excuses to roll out dough again.

Common Recipe Questions

→ Can I make the pasta dough ahead of time?

Yes, you can prepare the dough up to 24 hours in advance. Wrap it tightly in plastic wrap and refrigerate. Let it come to room temperature for about 30 minutes before rolling out, as cold dough can crack and become difficult to work with.

→ What can I substitute for burrata in the filling?

Ricotta is the best substitute, but make sure to drain it thoroughly in a fine-mesh sieve for at least an hour to avoid a watery filling. You could also use a mix of ricotta and mascarpone for added richness, though the texture will differ from the signature burrata creaminess.

→ How do I prevent the triangoli from opening while cooking?

Make sure to press the edges firmly when sealing, using a tiny dab of water or egg wash as glue. Avoid overfilling — one teaspoon per square is plenty. Also, keep the cooked triangoli in a single layer on a floured surface so they don't stick together and tear.

→ Can I freeze assembled triangoli before cooking?

Absolutely. Arrange the uncooked triangoli in a single layer on a floured baking sheet and freeze until solid, then transfer to an airtight container or freezer bag. They'll keep for up to 2 months. Cook directly from frozen, adding about 1–2 minutes to the boiling time.

→ Why do the leeks need to be cooked before filling the pasta?

Raw leeks contain too much moisture and have a harsh, sharp flavor that would overpower the delicate burrata. Cooking them slowly in butter until soft concentrates their natural sweetness and removes excess water, ensuring your filling stays creamy rather than soggy.

→ What type of breadcrumbs work best for the topping?

Fresh sourdough breadcrumbs give the best texture and flavor — they toast up crispy on the outside while staying slightly chewy inside. If you only have store-bought dried breadcrumbs, use them sparingly as they can become overly hard. Panko is a decent middle-ground alternative.
