Tips for making stuffed baked mushrooms

These mushrooms are pretty easy to make, but we do have a few tips:

  1. Be careful with the mushrooms, as they can fall apart easily. Gently wipe them down with a paper towel to clean.
  2. Use a spoon to pop out the stem of the mushrooms. Then, scrape out the sides to remove any ribs and make room for the sausage.
  3. Only cook the stuffed mushrooms for the 7-10 minutes as indicated. Watch them carefully at the end and pull them out before they get too soft.
  4. If needed, you can prep these in advance and bake them later. Just follow the steps and fill up the mushrooms with sausage. Cover and refrigerate until you’re ready to bake them.
