Why This Works

Cooking the minced mushrooms in a dry pan first drives off all their moisture before any fat goes in — add the butter too early and they steam instead of brown. What's left concentrates into a dark, jammy paste that's pure umami.

Ingredients

  • 8-12 oz mushrooms, finely chopped (cremini, button, or mixed)
  • 2-3 tbsp butter or olive oil
  • 1 small shallot or onion, minced
  • 1-2 cloves garlic (optional)
  • Fine salt, to taste
  • Black pepper, to taste
  • 1 tsp fresh thyme leaves (optional)

Method

  1. Chop: finely chop the mushrooms (food processor or knife) — minced but not pureed, consistent in size so they cook evenly.
  2. Cook dry: add the mushrooms to a dry skillet over medium-high heat and cook, stirring occasionally, until all their liquid releases and then evaporates, 10-15 minutes. Keep going until the pan is nearly dry.
  3. Add fat and aromatics: add the butter or oil, then the shallot (and garlic if using). Cook until the shallot is soft, 3-5 minutes. Season with salt, pepper, and thyme.
  4. Cook until jammy: keep cooking, stirring frequently, until the mixture is dark, concentrated, and thick enough to spread. Taste and adjust.

Notes

  • Spread on toast or crostini, mix into risotto or pasta, top a steak, fill puff pastry, or stir into soups for an umami boost.
  • Keeps 4-5 days refrigerated or up to 3 months frozen — an ice cube tray makes easy portions. Flavor improves with time.
  • If it turns dry or crumbly after refrigerating, stir in 1-2 tbsp crème fraîche to loosen it.
  • For a very large batch, oven-roast the chopped mushrooms at 400°F on sheet pans first (20-30 minutes) to drive off the moisture, then finish on the stovetop with the butter and aromatics.
  • Variations: a splash of brandy or sherry at the end, all butter for the richest version, mixed mushroom varieties, or fresh parsley to finish.
