Cook the macaroni in salted water according to the directions on the package.
In a medium saucepan, melt the butter over medium heat. Stir in the flour, salt, and pepper. Slowly add milk. Cook and stir until bubbling. Stir in horseradish and dill. Add the cheese and stir until melted. Fold in the lobster meat.
Drain the macaroni, add it to the cheese sauce and stir well to coat. Divide between 4 (12oz.) or 6 (8oz.) lightly greased ramekins.
Beat together the egg and milk to make an egg wash. Cut the puff pastry into 6 circles, slightly larger than the top of ramekins. Brush the outer edge of each circle with the egg wash. Place each crust egg-wash-side down on the filled dishes, lightly pressing the pastry onto the edge of the dish. Brush the crust with additional egg wash and sprinkle with quinoa if using. Cut a slit in the top of each crust so the steam can escape.
Place the ramekins on a baking sheet and bake for 20 minutes, or until the crust is golden brown and the filling is hot.
Allow to cool slightly before serving. Enjoy!
You can substitute lobster with crab meat. It'll be just as delicious!
If you like it spicy, you can add more horseradish or a pinch of crushed red pepper flakes.
I highly recommend smoked cheddar, but regular sharp cheddar can be used instead.
Always use freshly grated cheese for all cheesy recipes, as it melts better than prepackaged, and you'll get that gooey stringy effect with each bite.
Depending on the cheese you're using, you might have to add more salt - do it before you put macaroni mixture into ramekins.
You can use any small pasta instead of elbow macaroni.
Bake the whole thing as one pie if you don't have ramekins.
Place your ramekins upside-down on rolled out puff pastry (leaving about 1-inch space between them, then remove - they will leave a small indent in your pastry. Cut about ½-inch around the indent with a sharp knife. It doesn't have to be perfect; you're just trying to cut it larger than your ramekin.
This dish reheats well but the pastry, although it holds its shape, won't be as crisp. I'm sure you won't have any leftovers anyway.
