Umami Bomb Stuffed Mushrooms

Stuffed mushrooms are the cutest appetizer out there.

So round, so poppable, and so delicious. I absolutely love stuffed mushrooms. They’re easy to make (and make ahead if you need to) and they’re always a hit.

I love stuffed mushrooms and how infinitely customizable they are. They’re kind of like the vegetarian version of a deviled egg! I’m all about tiny bite-sized stuffed things and stuffed mushrooms fit the bill perfectly. These cheesy miso stuffed mushrooms are particularly good because they’re triple umami: mushrooms, miso, and parmesan cheese! They’re so full of flavor and satisfying.

How to Make Stuffed Mushrooms

  1. Prep the Mushrooms: Wash your mushrooms, trim the stems, and gently break the stems from the caps. Place the caps on a parchment paper-lined baking sheet.
  2. Sauté the Stems: Mince the stems and sauté them in butter until golden, then let cool.
  3. Mix the Filling: While the stems are cooling, mix together cream cheese, mayo, and a bit of white miso. Stir in the sautéed stems, then stuff the mushrooms, topping them with parmesan.
  4. Bake: Bake until golden and piping hot, then enjoy!

Helpful Hints

  • Washing Mushrooms: Wash mushrooms right before use. Place whole mushrooms in a sieve and spray off any dirt with cold water. Spin or pat dry with paper towels. Use immediately.
  • Choosing Mushrooms: Select mushrooms that are about the same size so they cook evenly. They should be whole, intact, and feel springy and light.
