Vegan interpretation of the Roman classic Spaghetti alla Carbonara (Lazio, Italy, c. mid-20th century); the vegan method is a modern adaptation with no traditional precedent.
Carbonara without eggs and cheese is an act of creative interpretation — the original, made exclusively with guanciale, eggs, Pecorino Romano, and black pepper, is one of the least adaptable classics in Italian cooking. A vegan version should not attempt to reproduce carbonara directly but to create a dish that achieves the same textural and flavour goals through different means: a silky, savoury, fatty coating on pasta with contrasting crispy-smoky bits and black pepper heat. The approach: cashews soaked and blended with nutritional yeast, miso, garlic, and pasta water achieve the silky, savoury coating; smoked tofu or mushroom bacon (thin-sliced mushrooms dried until chewy and crisped in oil with smoked paprika) provides the textural contrast. The result is not carbonara — it is a vegan pasta with a silky umami sauce, which is excellent on its own terms and should be framed as such.
Cashews soaked 4 hours minimum then blended smooth with nutritional yeast (for cheese depth) and white miso (for fermented complexity) form the sauce base Pasta water is essential — starchy, salty pasta water loosens the cashew sauce and helps it cling to the pasta Smoked protein substitute: smoked tofu pan-fried until crisp, or shiitake mushrooms dried and crisped with smoked paprika and soy sauce Black pepper must be fresh and generous — this is the characteristic spice element and cannot be reduced Sauce goes in off heat or over very gentle heat — cashew sauce can break if overheated Toss thoroughly until every strand is coated — the sauce should not pool at the bottom
A teaspoon of kala namak (black salt, from South Asian grocers) adds a sulphurous, egg-like note that is astonishing in its effectiveness for vegan applications For the mushroom bacon: thin-slice king oyster mushrooms, brush with a marinade of soy sauce, smoked paprika, maple syrup, and oil, and bake at 200°C for 20 minutes until chewy-crisp Nutritional yeast flakes scattered over at service give a slightly cheesy, nutty note that works as a Pecorino suggestion
Under-soaking cashews — insufficiently softened cashews produce a gritty sauce that won't blend smooth Forget the pasta water — the sauce will be too thick without it; add gradually until it coats the pasta smoothly Overheating after adding the sauce — the cashew emulsion can break under high heat Too little black pepper — the pepper is structural; be as generous as the Roman original Presenting it as carbonara — this is a vegan pasta with cashew sauce; calling it carbonara sets an expectation that will disappoint
