Hachis Flamand

5 from 1 review

This is seriously decadent, rich, delicious dish. It should serve 4. We (2) had it for dinner with enough leftover for 1 lunch. I did the nutrition info for 3 servings.


  • 2 medium onions, thinly sliced
  • 2 medium leeks, thinly sliced
  • 10oz (300gr) ground beef
  • 2oz (60gr) bacon, roughly chopped
  • 5oz (150gr) strong munster cheese, shredded
  • 5oz (150gr) crème fraîche
  • 2 tbs Dijon-style mustard
  • 1 tbs whole grain mustard
  • 2 tbs olive oil


  • Sauté the onions in 1 tbs olive oil until very soft and tender.
  • Add beef and brown, breaking it up as it cooks.
  • Add salt and pepper to taste.
  • Remove from skillet and set aside.
  • In same skillet sauté leeks and bacon in 1 tbs olive oil until leeks are soft and bacon is cooked.
  • In medium bowl stir together half the crème fraîche and both mustards.
  • Add beef, onions, mix well and put into a deep baking dish just large enough to hold everything.
  • Cover with leeks and bacon.
  • Combine the rest of the crème fraîche and cheese. Spread evenly over the top.
  • Bake at 400F (200C) until nicely browned, about 30 minutes.


Substitute sour cream for the crème fraîche.
