1. Heat oil in a medium saucepan over medium heat. Add onion to pan; cook 8 minutes or until tender, stirring occasionally. Add flour and garlic; cook 1 minute, stirring constantly. Stir in milk and bay leaf; bring to a boil. Cook 2 minutes or until thick, stirring constantly with a whisk. Add Gorgonzola, 1/2 cup Parmigiano-Reggiano, and salt; stir until cheeses melt. Discard bay leaf.

2. Preheat oven to 375°.

3. Cook pasta in boiling water 5 minutes or until almost tender, omitting salt and fat; drain well. Add pasta to cheese mixture, stirring well. Place about 1/2 cup pasta mixture into each of 6 (1-cup) ramekins coated with cooking spray. Sprinkle evenly with mozzarella. Top evenly with remaining pasta mixture. Combine remaining 1/4 cup Parmigiano-Reggiano and panko; sprinkle evenly over pasta mixture. Spray lightly with cooking spray; sprinkle with black pepper. Bake at 375° for 25 minutes or until heated.
