Ground Beef and Melting Cheddar Potato Gratin

Hamburger casserole is that dish people order in American diners without ever thinking of making it at home. Too complicated, too heavy, too many dishes — or so we think. In reality, it’s probably the simplest meal you’ll make this week.

Ingredients :

  • Ground beef — Go for ground beef with 15-20% fat content. Lean beef dries out during cooking and you lose all the juices that flavor the potatoes. Beef with a little fat is what gives this naturally savory sauce its depth without having to add a thousand spices.
  • Potatoes — Waxy potatoes — Charlotte, Monalisa, or any variety labeled ‘steaming’. Absolutely avoid: Bintje or floury types, as they fall apart and the casserole loses its structure. Slice to about 3mm, with a mandoline if you have one, or a knife otherwise — consistency is key.
  • Condensed soup — Cream of mushroom, cream of chicken, whatever you can find. It’s the base of the sauce and brings a creaminess that would be tedious to recreate otherwise. Don’t dilute it too much — half a cup of milk is enough to keep it nice and coating.
  • Cheddar — Mature for character, mild if you’re making it for kids. Crucial tip: grate it yourself. Pre-shredded bagged cheese contains anti-caking starch that prevents it from melting properly — you’ll end up with a grainy layer instead of a real golden crust.
