slat
- 8 tablespoon butter cut into 1 inch pieces
- 1/2 c panko bread crumbs
- 2 c finely grated parmesan cheese
- 1 tsp fresh lemon zest
- pepper
- 1 lb pasta
- 1 bunch broccoli rabe trimmed then cut into 1/2 inch pieces
- 1 c cream
- 1 small garlic clove minced
- 6 oz fresh mozzarella cut into 1/2 inch pieces
Heat the oven to 260c. Bring a large pot of generously salted water to a boil. Place the butter in a 9-by-13-inch/3-quart pan or baking dish and transfer it to the oven to melt while the oven heats; remove it from the oven once it’s melted.
In a small bowl, stir together the panko, 1/4 cup Parmesan and the lemon zest. Add 1 tablespoon of the melted butter from the baking pan, stir until the panko is moistened with butter, then season with salt and pepper.
When the water’s boiling, add the pasta and cook until al dente, about 2 minutes less than the package instructions suggest. During the last minute of cooking, add the broccoli rabe. Reserve 1/2 cup pasta water, then drain the pasta and broccoli rabe.
Whisk the cream, garlic and pasta water into the melted butter in the baking dish until smooth. Add the remaining Parmesan in large handfuls, vigorously whisking until smooth and combined. Add the pasta, broccoli rabe and half the mozzarella. Taste, and season well with salt and pepper. Stir until very combined.
Top with the remaining mozzarella, then sprinkle evenly with the panko mixture. Bake until the mozzarella has melted and the panko is golden brown, 10 to 15 minutes.
