My aunt taught me this brilliant 4-ingredient trick back when I first started juggling a full-time job and trying to eat something other than takeout. It’s basically the ultimate lazy spring meal: everything bakes together on one well-loved sheet pan, the pasta cooks right in the oven, and you end up with glossy, sauce-coated penne, crispy pancetta bits, and sweet roasted leeks. No separate pot of boiling water, no fancy steps—just toss, pour, bake, and eat. It’s perfect for those nights when you’re tired but still want something that feels like a real home-cooked dinner.
This sheet pan leek and pancetta penne is pretty much a one-pan wonder, but you can round it out with a simple green salad (mixed greens, lemon, olive oil, and salt) or some roasted asparagus to keep the spring vibes going. A glass of crisp white wine or sparkling water with lemon pairs nicely with the salty pancetta and sweet leeks. If you want to stretch it for more people, serve it with warm crusty bread to soak up the light, glossy sauce from the pan.
Oven-Baked Sheet Pan Leek and Pancetta PenneServings: 4
Ingredients
12 oz (340 g) dry penne pasta
8 oz (225 g) diced pancetta
3 medium leeks, white and light green parts only, thinly sliced and well rinsed
3 cups (720 ml) low-sodium chicken broth (or vegetable broth)
1 tbsp olive oil (for greasing the pan, optional)
1/2 tsp kosher salt, plus more to taste
1/2 tsp freshly ground black pepper
Directions
Preheat your oven to 400°F (200°C). Lightly grease a large, rimmed aluminum sheet pan with olive oil if it’s not already well-seasoned. Make sure the pan is large enough so the pasta can sit mostly in a single layer.
Spread the dry penne evenly over the sheet pan. It’s fine if some pieces overlap, but try not to pile them too high in one spot so they cook evenly.
Scatter the diced pancetta evenly over the dry pasta. As it bakes, the pancetta will crisp up and its fat will help flavor the pasta and leeks.
Add the sliced, well-rinsed leeks on top of the pasta and pancetta. Spread them out in an even layer. The leeks should be damp from rinsing but not dripping.
Season everything with the kosher salt and black pepper. Go light on the salt at this stage because the pancetta and broth both add saltiness.
Carefully pour the chicken broth over the entire pan, making sure most of the pasta is at least just-barely submerged or touching the liquid. Gently shake the pan or nudge the pasta with a spoon so the broth is evenly distributed.
Cover the sheet pan tightly with aluminum foil, crimping the edges to seal. This traps steam so the pasta can cook through in the oven without drying out.
Bake covered for 25 minutes. During this time, the pasta will absorb the broth and start to soften while the leeks turn tender.
Remove the foil carefully (watch for steam). Stir everything gently, making sure to scrape up any bits from the bottom so the pasta, leeks, and pancetta are well combined and the pasta is coated in the glossy broth.
Return the pan to the oven, uncovered, and bake for another 10–15 minutes, stirring once halfway through, until the pasta is al dente, most of the liquid has been absorbed into a light sauce, and the pancetta is browned and crisp in spots. The leeks should be soft with some lightly caramelized edges.
If the pasta looks too dry before it’s fully cooked, splash on an extra 1/4–1/2 cup of hot broth or water, stir, and continue baking for a few more minutes. If there’s still a bit of loose liquid at the bottom when the pasta is done, let the pan rest for 5 minutes; the pasta will soak it up and become nicely glossy.
Taste and adjust seasoning with a bit more salt and pepper if needed. Serve straight from the well-loved sheet pan for peak lazy-night energy, making sure everyone gets plenty of crispy pancetta bits and sweet roasted leeks.
Variations & Tips
To keep this close to the original 4-ingredient magic, the main players are penne, pancetta, leeks, and broth, but you can still tweak it a bit without adding much effort. For a slightly richer version, sprinkle a small handful of grated Parmesan or Pecorino over the top during the last 5 minutes of baking so it melts into the light sauce. If you want it creamier, stir in a splash of heavy cream or a spoonful of mascarpone after baking, while the pasta is still hot. To make it vegetarian, swap the pancetta for roughly chopped marinated artichokes or sun-dried tomatoes and use vegetable broth; you’ll lose the crisp pork bits, but still get big flavor. You can also switch up the pasta shape—other short, sturdy shapes like rigatoni or ziti work, but avoid very tiny pasta, which can overcook. If you’re meal prepping, this reheats well with a splash of broth or water to loosen the sauce; cover and warm in a low oven or microwave in short bursts, stirring in between. Food safety tips: Make sure the pancetta is kept refrigerated until you’re ready to cook and wash your hands and any surfaces after handling it. Leeks can trap dirt between their layers, so slice them first and then rinse thoroughly in a bowl of cold water, lifting them out so the grit stays behind. Leftovers should be cooled and refrigerated within 2 hours of baking and eaten within 3–4 days, reheating until steaming hot before serving.
