This portobello mushroom pizza is a perfect appetizer for a crowd, using the largest, flattest, mushroom caps you can find. These portabello mushroom pizzas are a crowd pleasing appetizer or even a family friendly vegetarian option. The beurre blanc, adds a taste of dining in a fine restaurant and is really super easy to make, I recommend using only the finest organic products you can find to make this little wonder. Grab a print and serve up some pizza at your next party or meatless family meal!

- 4 ( approximately 6-inch) portobello mushrooms, stems removed
- Cooking spray
- 2 cup chopped roma tomato
- 1 cup panko (Japanese) breadcrumbs
- 1 cup (4 ounces) preshredded part-skim mozzarella cheese
- ¼ cup chopped fresh chives
- ¼ teaspoon salt
- ¼ teaspoon black pepper
- 1 cup dry white wine
- ½ cup white wine vinegar
- 1 Tbsp finely chopped shallot
- 1 cup unsalted butter, cold
- Kosher salt, to taste
- Preheat broiler.
- Remove brown gills from the undersides of mushrooms using a spoon; discard gills
- Place mushrooms, gill sides down, on a foil-lined baking sheet coated with cooking spray.
- Broil the mushrooms for 5 minutes.
- While mushrooms broil, combine the tomatoes, panko breadcrumbs, cheese, and chives.
- Remove mushrooms from broiler.
- Turn mushrooms over, and sprinkle evenly with salt and pepper. Divide tomato mixture evenly among mushrooms.
- Return to broiler for approximately 5 minutes or until cheese melts.
- Swirl Beurre Blanc on to serving plate, placing mushrooms on top.
- Top warm mushrooms with remaining Beurre Blanc
- Heat wine, vinegar and shallots in a saucepan until the liquid boils, then lower the heat a bit and continue simmering until the liquid has reduced down to about 2 tablespoons.
- While the liquid reduces you can cut the butter into medium (½-inch) cubes, but either leave this until the reduction is nearly finished or return the butter cubes to the refrigerator to keep them cold while the liquid finishes reducing.
- Once the wine-vinegar mixture has reduced to 2 tablespoons, reduce the heat to low and start adding the cubes of butter, one or two at a time, and whisk rapidly with a wire whisk.
- As the butter melts and incorporates, add more butter and keep whisking. Continue until you only have 2-3 cubes remaining. Remove from heat while whisking in the last few cubes, and whisk for a moment or two more. The finished sauce should be thick and smooth.
- Pour through strainer to remove shallots. (You could leave these but your sauce will be lumpy)
- Season to taste with Kosher salt.
