Miso Pesto with Extra Fine Pasta

This is a clever vegan pesto that swaps the traditional Parmesan for miso paste, and the result is fuller and more savory than you might expect. Miso brings salt, umami, and a fermented backbone that replicates what cheese normally does in classic Genovese pesto.

Dry-toasting the pine nuts before grinding is the flavor-unlocking step most home cooks skip. Raw pine nuts taste waxy and flat, but a few minutes in a dry skillet until they go golden brown wakes up their oils and turns them sweet and buttery. Watch them closely, they burn fast.

A half cup of water blended into the sauce keeps this pesto pourable and silky instead of thick and pasty. Hot pasta drinks it up and the whole thing turns glossy on the plate.

Use a fine pasta like capellini, angel hair, or spaghettini, the thin strands grab the sauce where thicker shapes would feel under-dressed. Pour the pesto over hot pasta immediately after draining.

Chef Tips

• Use white or yellow miso for a sweeter, milder profile, red miso is too strong here.
• Reserve some pasta water for thinning, starch helps the sauce cling.
• Blend in two stages as directed, nuts last for the creamiest emulsion.
• Store leftover pesto under a film of olive oil in the fridge, keeps a week.

Variations

• Swap pine nuts for toasted walnuts or almonds.
• Mix half basil, half arugula for a peppery lift.
• Stir in a squeeze of lemon juice for brightness.
