Ground beef and potato gratins often get a bad reputation — too heavy, too bland, too much like school cafeteria food. Wrong. When done right, it’s one of the most satisfying dishes you can pull out of an oven. And doing it right doesn’t take much.

Ingredients :
- Yukon Gold Potatoes — Not just any variety. Yukon Golds have a firm flesh that holds up to long cooking without disintegrating. If you can’t find them, use Charlotte or Amandine — same logic. Avoid floury varieties like Bintje; they will turn into mush before the end.
- Canned Cream of Mushroom Soup — It does almost all the work for the sauce and provides a very useful umami base. If you prefer to avoid canned goods, a light béchamel with some blended mushrooms works — but honestly, the can gives a very good result here.
- Ground Beef — Use ground beef with at least 15% fat. Leaner meat stays dry and grainy after long cooking. You drain the excess fat released in the pan, but you need that fat base so the meat stays juicy in the gratin.
- Grated Cheddar — Grate it yourself if you can — bagged cheese contains anti-caking agents that block that beautiful stringy melt. A 12-month aged cheddar will provide much more character than a mild one.
