When it comes to smooth or ridged pasta, opinions are often formed too quickly. Many people consider ridged pasta better suited to holding sauce, while smooth pasta is sometimes seen as simpler or even less refined.
Ridges are a geometrical feature: they increase the surface area in contact with the sauce and are particularly effective with structured sauces, such as ragù. Yet they are not enough, on their own, to define the value of a pasta. High-quality pasta is the result of a carefully selected blend of durum wheat semolina for each shape and of a precise production method. This is what ultimately appears on the plate: from cooking resistance to the ability to create a harmonious relationship with the sauce.
For this reason, a smooth pasta that is bronze-drawn and slow-dried at low temperature can offer a very different result from what many imagine. Its surface remains rough and porous, naturally “open” to absorbing the sauce.
Today, it may sound surprising to say that the highest-quality pasta has traditionally often been smooth — when bronze-drawn and produced gently at low temperature. Think of Paccheri, Ziti and Maccheroni, a shape that had already become a familiar presence on Italian tables from the seventeenth century onward. Historically, ridges were introduced also to compensate for structural limits in the dough, often linked to the use of wheat with weaker proteins. The ridge acted as a structural reinforcement, giving the shape the firmness that the raw material alone could not provide.
Smooth pasta is therefore a pasta of great quality when it comes from a method designed to preserve structure, chewiness and the ability to blend with sauce. Among the many types of pasta, smooth shapes are those that most clearly reveal the value of the production process: without ridges to rely on, they allow thickness, texture and even cooking to speak more directly.
In the case of Benedetto Cavalieri pasta, the Delicate Method is based on precise steps: prolonged kneading, slow mixing and pressing, bronze drawing and low-temperature drying. It is the coherence of this entire process that allows the pasta to preserve its wheat flavour, natural texture and great ability to blend with sauce.
Ridges can certainly be useful in creating a different sensation on the palate — and diversity is part of the pleasure of pasta — but they cannot replace the method. Ridged pasta produced without due care may lack character; smooth pasta made with precision has a full bite, and its surface, capable of welcoming the sauce, gives the dish remarkable pleasure and balance.
The point is not to decide, in absolute terms, whether smooth pasta is better than ridged pasta. It is to understand how smooth pasta and ridged pasta respond differently.
Smooth pasta is ideal with creamy and dense sauces that spread evenly across the whole surface.
Penne Lisce are especially interesting with a roasted pepper cream, basil and toasted breadcrumbs, or with a sweet tomato sauce, well reduced and blended with a drizzle of extra virgin olive oil. In these cases, the smooth surface gives the bite a more even texture and allows the consistency of the pasta to come through more clearly.
Maccheroni are worth trying “alla Genovese”, with onions slowly stewed until sweet and almost melted, together with a meat sauce — traditionally beef — cooked gently until exceptionally tender.
Small smooth short pasta shapes, such as Tubetti Lisci, are also ideal in preparations where pasta, legumes and vegetables need to come together: pasta with chickpeas, a thick potato soup, or a cream of beans finished with olive oil and rosemary.
Ridged pasta is particularly suitable when the sauce needs more grip. The grooves help “capture” the sauce more effectively, especially with full-bodied sauces, diced vegetables or ragù.
Penne Rigate are a classic example: their ridged surface and oblique cut make them highly versatile, particularly suited to pasta alla Norma, where creamy elements and more substantial pieces alternate in the same dish.
Rigatoni hold sauce through their ridges and welcome it inside their generous diameter. Mezzi Rigatoni are also perfect with ragù and meat sauces: a very balanced choice when looking for a short, structured shape for an important sauce. Rigatoni and Mezzi Rigatoni are especially well suited to classic Roman recipes such as Amatriciana and Carbonara.
The comparison between Penne Lisce and Penne Rigate is perhaps the most meaningful one. They have a similar shape — tubular, with an oblique cut — but they behave differently on the palate. Penne Lisce enhance continuity: they accompany creamy, silky, well-emulsified sauces. Penne Rigate, on the other hand, enhance grip: they are better suited to dense, rich, irregular sauces.
The difference is not a hierarchy. Smooth or ridged, each shape has its own “character” and its ideal use. It is a matter of pairing, gastronomic tradition and, sometimes, personal taste.
Penne Lisce ask for a precise and “correct” finishing in the pan; Penne Rigate are more forgiving with less homogeneous sauces. But when the pasta is truly high quality, both can deliver extraordinary results.
There are also smooth pasta shapes with a very strong geometry. Paccheri and Mezzi Paccheri show that a smooth surface can have extraordinary expressive power. Here, it is not the ridge that holds the sauce. It is the diameter, the thickness, the hollow centre and the delightful chewiness that make the dish stand apart.
Paccheri are well suited to seafood sauces, fresh tomato, swordfish, shellfish or delicate white ragù. Mezzi Paccheri have the same thickness and diameter as Paccheri, but they are more practical to eat in a single bite, without needing to be cut. They are a more manageable shape on the plate, while preserving the thickness and pleasure of Paccheri.
