This dish is super easy and incredibly tasty.
Split the langoustines and remove their shells and intestines.
Place them in a tea towel and dry them thoroughly.
Peel the garlic and press it through a garlic press into the butter.
Stir well in the mixture so the garlic pieces are evenly distributed.
If you don't have a clove of garlic, you can easily use garlic powder. Another alternative could also be store-bought/homemade garlic butter.
Distribute 8 langoustine tails in two ramekins and add half of the butter on top of each.
Finally, sprinkle grated cheese over and place it in a hot oven.
Cook it for 10-15 minutes at 200 degrees Celsius (392 degrees Fahrenheit) with fan.
The goal is for the cheese on top to turn golden.
When the cheese is golden, they are ready to serve - but be careful, they are piping hot.
