Miso Butter Mushroom Pasta

Umami-packed mushrooms tossed with pasta in a miso-butter sauce. Meat-free, deeply savory, quietly luxurious.

Mushroom pasta with herbs in a creamy miso butter sauce

Method

Instructions

  1. 1

    Cook the pasta

    10 min

    Cook the pasta in generously salted boiling water until al dente. Reserve a cup of the cooking water before draining.

  2. 2

    Brown the mushrooms

    7 min

    Heat the olive oil and 1 tablespoon of butter in a large skillet over medium-high heat. Add the mushrooms in a single layer and cook, undisturbed, until deeply browned, 4–5 minutes, then toss and cook 2 minutes more. Season lightly.

    Tip: Leave the mushrooms alone while they brown — moving them too soon makes them steam instead.

  3. 3

    Build the sauce

    2 min

    Lower the heat to medium, add the remaining butter and the garlic, and cook until fragrant, 1 minute. Stir in the miso and 120 ml of pasta water, scraping up the fond, until smooth.

  4. 4

    Toss and finish

    2 min

    Add the pasta to the skillet and toss until every strand is coated, adding more pasta water if needed. Taste and season, then finish with chives.

    Tip: The sauce should coat the pasta loosely — add pasta water a splash at a time.

Cooking Tips

  • Tear, don’t slice, the mushrooms — ragged edges brown better and catch the sauce.
  • Miso is salty, so taste before adding extra salt.
  • White miso is mellow; brown/red miso is stronger — adjust the amount if you swap.

Good to know

Common Questions

What does miso do in a pasta sauce?

It adds deep, salty umami — like parmesan, but from fermented soy. It dissolves into the butter for a silky, savory sauce.

Can I use any mushrooms?

Yes, but a mix of cremini and shiitake gives the best depth. Button mushrooms work too; just brown them properly.

Is this recipe vegan?

Nearly — swap the butter for olive oil or vegan butter and it is fully plant-based.
