Minced beef in gravy under mashed potatoes, the oldest casserole here. Ours is the weeknight version: Beef base from the freezer, a bag of frozen vegetables, and stock thickened into gravy in the same pan, so the only real cooking is the potatoes.
Picks
Savoury and rich, under a soft, browned lid.
- The starch: Mashed potatoes on top, stiff enough to ridge
- The filling: Beef base and frozen peas, corn, and carrots
- The sauce: Stock thickened into a beef gravy in the pan
- The top and the bake: Mash ridged with a fork and a little cheddar, browned under the broiler
Where it comes from
“Cottage pie” is first recorded in 1791, and “shepherd’s pie” in the 19th century; the two names have been used for the same dish since (Wikipedia). Before refrigeration, a Sunday roast was cooked to last the week, and what was left of it was minced and baked under potato.
| Constraint | Pick it explains |
|---|---|
| Leftover roast, and no fridge to keep it | Cooked meat, minced and stretched in gravy |
| Potatoes are cheap and filling | A thick lid of mash |
| One oven, one dish | Baked, not served in parts |
Some say cottage pie is beef and shepherd’s pie is lamb, but that distinction came later; in Canada either name can mean any meat under mash.
Why these picks
- Beef base. It’s already braisedBraiseBrown, then cook slowly in a covered pot, part-way submerged in liquid, until a tough cut turns tender. and seasoned, so the filling is ready in the time the potatoes take.
- Frozen vegetables. They go in frozen, cook in the bake, and stretch the beef.
- Steamed potatoes. Drier than boiled, so the mash holds its ridges and browns.
How it fails
- The mash sinks: the filling was too thin. Simmer it until thick before it goes in the dish.
- Pale top: no broiler. The ridges are what brown.
Variations
- Shepherd’s pie: lamb in place of the beef.
- Vegetarian: a lentil base, or chili, in place of the beef.
