Mushroom Pesto Toasts – Wonderful Appetizer to Please the Crowd
These Mushroom Pesto Toasts were inspired by the dish that I once saw on Food Network: Grilled French Bread Pizza with Mushroom Pesto and Fontina Cheese I where Bobby Flay was making it on the outdoor grill. I made these Mushroom Peto Toasts for some house guests in the middle of a brutal New York winter.
Given the frigid temps, obviously, this means no outside grill. Instead of grilling I decided to sautee my mushrooms in a pan, and use the oven to bake my toasts. Let me tell you my version of these mushroom pesto toasts came out so delicious that my guests and I were in heaven.
The richness of the pesto, with a hint of Pecorino Romano – with its smooth texture – and then the gooey fontina…..mmmm….it created a happy dance in my mouth. My guests totally favored these over any other dishes that I’d made that day and they couldn’t get enough.
So if you’re looking for a crowd-pleasing appetizer, look no further. Make these amazing Mushroom Pesto Toasts with Fontina Cheese and you will see how pleased your crowd will be.:)
