Why It Works

  • Using mushrooms that are at least 1 1/2-inch in diameter allows you to stuff them with a generous amount of filling.
  • Baking the mushrooms in a cast iron skillet at a high temperature cooks them quickly and prevents them from becoming soggy.

I was vegetarian for almost a decade. What I remember most from that time—besides people constantly asking if there was enough protein in my diet—is the sheer amount of mushrooms I ate. (Which was great, since mushrooms are extremely delicious!) At restaurants, vegetarian options almost always included a risotto or creamy pasta with mushrooms. At dinner parties, friends whipped up meat-free versions of beouf Bourguignon packed with creminis, shiitakes, and oyster mushrooms for me. And at cook-outs, I grilled hefty portobello mushrooms to sandwich between burger buns with lettuce and tomatoes.

Though I am no longer vegetarian, I still frequently fold mushrooms into soups, stews, and salads for their savory depth of flavor. They are also the star of one of my favorite appetizers: stuffed mushrooms. At their best, stuffed mushrooms pack a lot of flavor into a small package, hitting savory, sweet, and especially umami notes all at once. They combine textures—a creamy filling, crispy topping, and a tender, never soggy, and perfectly browned exterior—and are small enough to eat in one bite, making them the ideal party food. At their worst, they’re soggy, bland, and rubbery, and probably the last thing you want to eat. Luckily for us (and you!), our Birmingham, Alabama-based test kitchen colleague Renu Dhar has a stellar recipe for vegetarian stuffed mushrooms.

Renu’s stuffed mushrooms tick all the boxes: They have cream cheese and Parmigiano-Reggiano for richness, chopped mushroom stems for a meaty bite, and sun-dried tomatoes that bring a touch of sweetness. Panko breadcrumbs provide a satisfying crunch, and a clever method prevents the mushrooms from getting soggy. Instead of having you bake your mushrooms on a sheet pan or in a baking dish, she has you use a cast iron skillet, which retains heat well and effectively browns the bottom of the mushrooms. “Between the high heat [of the oven] and the heat from the cast iron, the mushrooms get cooked really fast,” says Renu, “which guarantees they don’t turn soggy.”

The result? Delicious, savory stuffed mushrooms that two testers separately described as having “marry me” vibes. You certainly don’t have to be a vegetarian to enjoy these, nor do you need to have a special occasion to make them. With just 20 minutes of prep time and another 25 minutes in the oven, you could have a spectacular mushroom feast for you and your family in less than an hour, which is a party in itself.

Ingredients

  • 12 large cremini mushrooms (12 ounces; 340g), cleaned and stemmed, stems reserved

  • 1/4 cup julienned sun-dried tomatoes packed in oil (1 3/4 ounces; 50g), drained and finely chopped, plus 2 tablespoon (30ml) oil from jar, divided

  • 1/4 teaspoon Diamond Crystal kosher salt; for table salt, use half as much by volume

  • 3 tablespoons cream cheese (1 1/2 ounces; 42g), at room temperature

  • 1/4 cup Parmigiano-Reggiano (1 ounce; 28g), finely grated

  • 1/4 cup panko breadcrumbs (1 ounce; 28g)

  • 1 teaspoon dried oregano

  • 1/2 teaspoon garlic powder

  • 1/2 teaspoon freshly ground black pepper

Directions

  1. Adjust oven rack to middle position and preheat oven to 425°F (220ºC). Finely chop reserved mushroom stems; set aside. In a 10-inch cast iron skillet, heat 1 tablespoon sun-dried tomato oil over medium heat until just shimmering, about 3 minutes. Add mushroom stems and salt; cook, stirring, frequently, until mushroom stems are browned, about 3 minutes. Transfer mushroom stems to a medium bowl; let cool for 5 minutes. Wipe skillet clean.
