I make these all the time, they are an excellent recipe! They do freeze well, I let mine sit out for about ten minutes before I put them in the oven (from the freezer). If you like mushrooms, I highly recommend this recipe!!

  1. First, make the croustades: generously butter small muffin tins, then cut a 3-inch round from each slice of bread and carefully fit into the muffin tins.
  2. Bake in preheated 400F oven for 10 minutes, or until rims are lightly browned; remove from tins and cool (may be frozen at this point).
  3. Now make filling.
  4. In a skillet, melt butter, then saute onions and mushrooms; stir and cook until all the moisture is evaporated.
  5. Sprinkle with flour, then stir thoroughly.
  6. Add cream, stirring constantly until it boils.
  7. Add wine, reduce heat, and simmer a few minutes longer.
  8. Remove from heat; stir in salt, cayenne, parsley and green onion.
  9. Transfer to a bowl; cover and refrigerate until needed.
  10. To serve, preheat oven to 350F; spoon mushroom filling into croustades; lightly sprinkle with parmesan and place on cookie sheet.
