Roasted Vegetable Pipe Rigate Pasta

This is the pasta dish that stops the scroll: whole eggplants, sweet red peppers, ripe tomatoes, and onions are roasted until they collapse into a velvety, jammy sauce, then tossed with pipe rigate shells and a generous handful of melted mozzarella.

The result is a deeply savory, slightly sweet, and utterly comforting dinner that tastes like it simmered for hours — but comes together in under an hour. Every shell traps a bit of the chunky vegetable sauce and a long, gooey string of cheese.

Pipe rigate are short, curved pasta tubes with ridges that are ideal for catching thick, chunky sauces. Here, they're paired with a sauce made from whole roasted vegetables — no chopping, no peeling, no fuss. The vegetables are simply placed in a pan with a little oil and water, roasted until tender, then mashed into a rustic puree.

The natural sugars in the peppers and tomatoes caramelize as they roast, giving the sauce a deep, complex sweetness. A handful of mozzarella melts into the pasta, creating long, satisfying cheese pulls. This is a one-pan wonder that delivers big flavor with minimal effort.

Ingredients

Why this recipe works

Roasting the vegetables whole is the secret here. It allows them to cook in their own steam, which keeps them moist and tender while concentrating their flavors. The high heat caramelizes the natural sugars in the peppers and onions, while the tomatoes burst and release their juices, creating a rich, savory base. Because the vegetables are not cut, they don't dry out or burn — they simply soften and meld together into a silky, jammy texture.

Mashing the vegetables, rather than pureeing them, gives the sauce a hearty, rustic consistency that clings beautifully to the pasta. The starchy pasta water helps to bind the sauce and cheese, creating a glossy, emulsified coating. The mozzarella adds a mild, milky richness that balances the acidity of the tomatoes. The result is a sauce that is both robust and velvety, with every bite offering a different texture and flavor.

Notes and substitutions

Choose eggplants and peppers that are firm and glossy, with no soft spots. Ripe, in-season tomatoes will give the best flavor, but canned whole tomatoes can be substituted in a pinch — just drain them well.

The recipe calls for whole vegetables, so there's no need to peel or seed anything; the skins soften during roasting and add texture to the sauce. If you prefer a smoother sauce, you can remove the pepper skins after roasting, but the rustic version is part of the charm.

Pipe rigate are the classic choice here because their shape traps the sauce and cheese, but any short, ridged pasta like rigatoni or penne will work. For a gluten-free version, use your favorite gluten-free pasta and adjust the cooking time accordingly.

The fresh dill adds a bright, herbaceous note that cuts through the richness; if you don't have dill, fresh basil or parsley are excellent alternatives. This dish is vegetarian as written, and you can easily make it vegan by using a dairy-free cheese alternative.
