We eat alot of leeks here in Belgium. This has to be one of my favorite ways to prepare and eat them. The cheese sauce doesn't overpower or mask their flavor, it simply complements it.
- Pre-heat oven to 200°C.
- Cut the root-ends from the leeks, and cut them in 5 cm (2 inch) pieces, keeping only the white parts and the tender green inner parts; wash well in water.
- Place the leeks in boiling water and simmer for 10 minutes; drain well, then arrange in a baking dish (I use a 1 1/2 liter size that is 14 1/2 cm square).
- As your leeks are simmering, put the milk, flour, butter, and bay leaf in a saucepan, and mix well.
- Bring to the boil, whisking continuously; simmer for 2 to 3 minutes, until the mixture thickens.
- Add garlic powder, salt, mustard powder and nutmeg, then 3/4 of the grated cheese, whisking until it is completely melted.
- Remove the bayleaf, then pour the cheese sauce over the leeks.
- Top with remaining cheddar, and bake 20-30 minutes, until golden.
- If possible, let stand 5-10 minutes before serving to allow the cheese sauce to further"set" and to avoid burning your mouth.
Gorgeous receipe and easy to follow
I loved the cheese sauce, it was perfect. This was my first time eating leeks au gratin and I quite liked it, but found the leeks a bit stronger tasting than I thought they would be. I will certainly make this again and I thank you for the recipe.
I used leeks from my garden and they were on the small side so I had much more sauce than leeks. The sauce was very good and I agree it would be good with any vegetable. I also think I would saute the leeks next time for just a little extra flavor.
