Grilled Chicken-and-Bacon Mac 'n' Cheese

Preheat oven to 375 F. Arrange the bacon on a slotted broiler pan or on a rack placed over a baking sheet and bake until crisp, about 15 minutes. Chop and reserve. Switch on the broiler and position the rack in the center of the oven.

Bring a pot of water to boil, salt it, add pasta and cook 1 minute less then instructions indicate, or until just shy of al dente. Drain and return to the pot.

While pasta is working, heat grill pan or cast-iron griddle over medium-high heat. Drizzle chicken with EVOO to coat lightly then season evenly with paprika, salt and pepper. Grill chicken for about 10 minutes, turning occasionally. Transfer to a cutting board and halve the pieces lengthwise, then thinly slice crosswise.

While the chicken cooks, melt the butter in a medium saucepan over medium heat. Add the onion and cook until light golden brown and very soft, 15 to 20 minutes. Sprinkle in the flour and stir for 1 minute. Whisk in cider (or stock), then add milk. Bring to a boil and cook, whisking, until the sauce coats the back of a spoon, 3 to 4 minutes. Add thyme and season with salt, pepper and nutmeg. Stir in the cheese until melted.

Add the chicken, bacon and sauce to the pasta and transfer to a casserole. Broil until bubbling and browned, about 5 minutes. Garnish with parsley or celery greens.
