This lobster mac and cheese pie, Irish-style, is completely irresistible. It’s the kind of comfort food you order when you want something special—and once you try it, you’ll understand why.

Homemade mac and cheese is easy to make and far superior to the boxed version. You can keep it simple or elevate it with quality ingredients—this pie leans toward the luxurious, thanks to smoked cheddar, fresh dill, horseradish, and tender lobster.

Every first Tuesday of the month, Bobbi of Healthy World Cuisine and I share a noodle-inspired recipe from somewhere around the globe. If you create your own noodle dishes, tag them with #noodleswithoutborders on Instagram for a chance to be featured.
If you’re nervous about making a more advanced recipe but still want to impress, lobster mac and cheese pie is an excellent place to start. Make small individual pies to serve at a party, or bake one large pie for a family meal—both versions are delicious.
🔪 Instructions

This recipe is quick to assemble, especially if you keep cooked lobster and puff pastry on hand. Follow these straightforward steps for a reliable result:
- Preheat the oven to 400°F (200°C).
- Cook the macaroni in salted water according to package directions, then drain.
- In a saucepan over medium heat, melt the butter. Stir in the flour, smoked salt, and black pepper to form a roux. Slowly whisk in the milk and cook, stirring, until the sauce bubbles and thickens.
- Stir in the horseradish and fresh dill. Add the shredded smoked cheddar and stir until melted, then fold in the lobster meat.
- Combine the drained macaroni with the cheese and lobster sauce, mixing until well coated. Spoon the mixture into lightly greased ramekins (or a single baking dish).
- Beat the egg with 1 tablespoon of milk to make an egg wash. Cut puff pastry into circles slightly larger than your ramekin tops. Brush the edges of each pastry circle with egg wash and place them over the filled ramekins, pressing gently to seal. Brush the tops with more egg wash and cut a small slit to allow steam to escape. Optionally sprinkle with quinoa for texture.
- Place the ramekins on a baking sheet and bake for about 20 minutes, until the pastry is golden and the filling is hot. Allow to cool briefly before serving.
- Substitute crab meat for lobster if preferred—results are excellent.
- Add more horseradish or a pinch of red pepper flakes if you like heat.
- Smoked cheddar gives the best flavor, but a sharp cheddar will also work.
- Always grate your own cheese—the melt is superior to pre-shredded varieties.
- Taste the sauce before filling ramekins and adjust salt if needed.
- Any small pasta can replace elbow macaroni.
- If you don’t have ramekins, bake this as a single pie in a baking dish.
- For individual pies, place ramekins upside down on rolled puff pastry to mark and cut circles slightly larger than each ramekin.
- Leftovers reheat well, although the pastry won’t be as crisp as when freshly baked.
- Pairs nicely with a light red such as pinot noir.
Each bite delivers creamy, smoky cheese, delicate lobster, and a flaky, golden pastry top. This is grown-up comfort food at its best—rich, satisfying, and perfect for special occasions or an indulgent weeknight meal.
