WOW! This was soooo delicious! I reduced the quantity of potatoes for 2 persons (2 medium potatoes for each of us) but made the same quantity of sauce.
I saved half of the sauce for my green asparagus and both, potatoes gratins and asparagus turned out soooo delicous!

I substituted the thyme by fresh (4 tablespoons) savory; as mustard I used the Dijon mustard with whole seeds!

Ingredients (for 4 persons):

  • 800 grams potatoes (peeled)
  • 50 grams butter
  • 2 spring onions (scallions, finely sliced or 1 small brown onion, finely chopped)
  • 2 garlic cloves (crushed or minced)
  • 2 tablespoons all-purpose flour (plain)
  • 1 cup milk (warmed)
  • 2 teaspoons coarse grain mustard
  • 1 teaspoon thyme leaves (fresh and chopped)
  • 1 cup grated cheese (tasty cheese)
  • 1/4 cup dried breadcrumbs, I forgot this ingredient!
