Recipe ingredients

Labeled ingredients for marinated mushrooms

Ingredient notes

  • Mushrooms: I love the flavor of cremini mushrooms, but white button mushrooms or baby bellas are fine too. If the mushrooms are small, you don’t need to cut them in half.
  • Red onion: Or substitute ¼ cup minced shallot.
  • Oregano: Or substitute 1 ½ teaspoons minced fresh oregano.
  • Crushed red pepper flakes: These are optional, but I love the kick just a pinch adds to these mushrooms.

Step-by-step instructions

  1. In a Dutch oven or large pot, bring 8 cups water and 2 tablespoons salt to a boil. Add mushrooms and cook until tender, about 3 to 4 minutes. Remove mushrooms from water and drain well.

Recipe tips and variations

  • Yield: This recipe makes about 4 cups marinated mushrooms, enough for 4 as a side dish or more as part of an antipasto platter.
  • Storage: Store covered in the refrigerator for up to 4 days.
  • Make ahead: While they can be eaten after just 5 minutes of chilling, these mushrooms are best made ahead and chilled for at least 8 hours. Make them up to 3 days ahead, especially for parties and holidays when you’re way too busy anyway.
  • Canning: Because mushrooms are a low-acid food, these marinated mushrooms are not safe for home canning.
  • Pairing ideas: Marinated Mushrooms are remarkably versatile. Try them on or alongside lemon pepper chicken, grilled pork tenderloin, or prime rib, stuffed inside an omelet or baked potato, or as part of a Midwest Charcuterie Board.
