Shrimp-Stuffed Baby Portobellos

I love stuffed mushrooms, but I never order them in restaurants because, well, five is simply not enough and when you're out in public, you have to play nice and share. The thought of eating only one stuffed mushroom makes me immensely sad. But LOOK, if you make them yourself, you can eat twenty of them, drink a bottle of wine, and then roll straight into bed. It's a win-win...winwinwin situation. Granted, you'll feel like a sack of melty potatoes for the rest of the evening, but it's a pleasurable pain and perfect for a special occasion.
Like a Wednesday.

Shrimp-Stuffed Portobello Mushrooms
Bon Appetit

1/4 cup olive oil
1/2 cup chopped onion
1/4 cup chopped fresh basil
3 large garlic cloves, chopped
1/2 teaspoon chopped fresh rosemary
6 ounces cooked bay shrimp [chopped shrimp works just great as well]
2/3 cup fresh breadcrumbs from French bread
1/2 cup grated Parmesan cheese
1/4 cup mayonnaise
24 baby portobello mushrooms, stems & gills removed

(Breadcrumbs can be made easily by cutting the crust off a few slices of slightly stale or aired-out bread and popping them in the food processor. I thought I could be clever and shorten the process by grating the bread on a cheese grater. This, I promise you, is most definitely not easier or quicker.)

Heat the oil in heavy skillet over medium-high heat.

Add in the onion, basil, garlic, and rosemary. Sauté until onion softens (approximately 5 minutes), and transfer to medium-sized bowl.

Mix in the shrimp, breadcrumbs, cheese, and mayonnaise. Season to taste with salt and pepper.

Preheat oven to 350°F. Arrange the mushrooms, top down, on lighoiled baking sheet. Mound shrimp filling in mushrooms, pressing filling to compact slightly. Bake mushrooms until tender and filling begins to brown, about 35 minutes. Serve hot. (Not a problem because they're so delicious you'll want to eat them all before you even get them onto a plate.)

[These can be made 6 hours ahead of time, just cover and refrigerate until ready to bake. MAGIC.]
