Stuffed Mushroom Caps

seafood stuffed mushrooms

Stuffed mushrooms make a wonderful appetizer and can even fill in as a main course. At their best, stuffed mushrooms are savory and delicious. However, if you don't prepare them properly, they can be slimy and tasteless. With the right prep work, recipe and mushroom selection, you'll have tasty, well-made stuffed mushrooms every time.

Choosing Mushrooms

It's important to choose mushrooms that are large enough to accommodate stuffing without being so huge that they move beyond bite-sized. Mushrooms shrink during cooking, so you should select large, white button mushrooms or crimini mushrooms. Crimini mushrooms will add a hearty, almost meaty mushroom flavor, while white button mushrooms tend to have a more mild flavor.

Preparing the Mushrooms

After you have selected appropriately-sized mushrooms, you need to prepare them before you stuff.

  1. Use a mushroom brush or paper towel and gently remove any debris. Never wash or submerge mushrooms. The fungus acts like a small sponge, soaking up as much liquid as it can. If you wash or submerge your mushrooms, they will become mushy and watery.
  2. Remove the entire stem of the mushroom and make room for a little additional filling by using a melon baller to further hollow out the mushroom if needed.
  3. Pre-brown your mushrooms on a lightly oiled baking sheet at 350F in the oven. Mushrooms should be hollowed-side up. Brown them for five to eight minutes, until the mushrooms begin to release their liquid. When they are slightly brown, remove them from the oven and cool. Once they are cool you can use a paper towel to remove any extra liquid.

  1. Preheat oven to 450 degrees.
  2. Crumble sausage into a sauté pan and cook about four minutes.
  3. In a food processor, combine garlic, mushroom stems, celery, onion, pepper and spinach. Pulse six or seven times to chop.

Consider the following for successful mushrooms.

  • Err on the side of dry stuffing. Even with pre-browning, the mushrooms will release additional moisture. A drier stuffing will soak up the excess.
  • Don't skip the pre-browning process, or your mushrooms will wind up mushy.
  • Mix cheese into fillings instead of sprinkling on top. If you want an extra brown topping, sprinkle with bread crumbs and broil for a few minutes.
