Italian Seafood Portobellos

SHRIMP-STUFFED PORTOBELLO MUSHROOMS

Steps:

• Heat oil in heavy large skillet over medium-high heat. Add onion, basil, garlic, and rosemary. Sauté until onion softens, about 5 minutes. Transfer to medium bowl; mix in shrimp, breadcrumbs, cheese, and mayonnaise. Season filling to taste with salt and pepper. Arrange mushrooms, rounded side down, on oiled baking sheet. Mound shrimp filling in mushrooms, pressing filling to compact slightly. (Can be made 6 hours ahead. Cover and refrigerate.)
• Preheat oven to 350°F. Bake mushrooms until tender and filling begins to brown, about 35 minutes. Serve hot.

PESTO-STUFFED GRILLED PORTOBELLOS

Steps:

• Remove stems from mushrooms and finely chop stems.
• Heat olive oil in a skillet over medium heat; cook and stir chopped mushroom stems, shallot, and garlic until softened, about 5 minutes. Pour wine into the skillet; cook and stir mixture using a wooden spoon until liquid is evaporated, 1 to 2 minutes. Cool mixture to room temperature, about 10 minutes.
• Preheat an outdoor grill for medium heat and lightly oil the grate.
• Brush the olive oil mixture over the top each mushroom and place, top-side up, on a grilling pan. Mix pesto and pine nuts with the mushroom stem mixture together in a bowl; spoon into each mushroom. Sprinkle Italian cheese blend over the filling.
• Grill mushrooms on the preheated grill until edges are blackened and stuffing is bubbling, about 10 minutes.
