One-Pan Roasted Tomato and Zucchini Tagliatelle with Mozzarella

This roasted tomato and zucchini tagliatelle is the ultimate one-pan pasta dinner. Sweet, caramelized tomatoes and tender zucchini are simmered into a rich, chunky sauce, then tossed with silky tagliatelle and a generous handful of mozzarella and parmesan. The result is a creamy, cheesy pasta that feels indulgent but comes together in under 30 minutes. Perfect for busy weeknights when you crave something comforting and satisfying without a pile of dishes.

This recipe celebrates the simplicity of ripe tomatoes and fresh zucchini, transformed into a luscious sauce right in the skillet. The vegetables are sautéed until caramelized, then crushed to release their natural sweetness.

A splash of starchy pasta water helps the sauce cling to every strand of tagliatelle, while mozzarella and parmesan melt into a creamy, stretchy finish. The entire dish cooks in one pan (plus a pot for the pasta), making cleanup a breeze. Serve it as a hearty weeknight dinner or a casual weekend favorite.

Ingredients

Why this recipe works

Sautéing the tomatoes and zucchini until caramelized concentrates their flavors and brings out their natural sugars. Crushing them with a wooden spoon creates a rustic, chunky sauce without the need for a blender or food processor — less equipment, less fuss. The starchy pasta water acts as a binder, helping the sauce adhere to the noodles and giving it a silky, cohesive texture. This method builds layers of flavor in a single pan, proving that great pasta doesn't require a dozen pots and a long simmer.

Adding the cheeses off the heat and tossing gently allows them to melt slowly into the sauce, creating a creamy emulsion without breaking or turning greasy. The combination of fresh mozzarella and aged parmesan delivers both stretch and depth of flavor — mozzarella for that glorious cheese pull, parmesan for its nutty, salty bite.

The result is a sauce that coats each strand of pasta evenly, with a luxurious mouthfeel that feels rich but not heavy. This technique ensures every bite is as creamy and satisfying as the last.

Notes and substitutions

Use ripe, in-season plum tomatoes for the best flavor — they are meaty and sweet, ideal for cooking down into a sauce. If plum tomatoes are not available, cherry tomatoes or Roma tomatoes work well. Zucchini should be firm and fresh; slice them into half-moons so they cook evenly and soften without turning mushy.

Fresh mozzarella is preferred for its stretch, but low-moisture mozzarella can be substituted — just shred it yourself for better melting. Grated parmesan from a wedge melts more smoothly than pre-shredded varieties, which often contain anti-caking agents.

Tagliatelle is the classic choice, but fettuccine, pappardelle, or any long pasta will work. Cook the pasta until al dente — it will finish cooking briefly in the sauce, so a firm bite is ideal. The starchy pasta water is crucial: it thickens the sauce and helps it cling.

Reserve a full cup, even if the recipe calls for less, so you can adjust the consistency at the end. If you prefer a spicier dish, add a pinch of red pepper flakes with the garlic. Fresh basil is a must for garnish — its bright, aromatic flavor cuts through the richness beautifully.
