Common Questions
Is this technically cottage pie or shepherd’s pie?
Classic shepherd’s pie uses lamb. Beef versions are often called cottage pie. Most of us call it shepherd’s pie anyway. Use whichever name makes your kitchen happiest.
What pan size should I use?
For the amounts listed here (1 pound beef, 2 pounds potatoes), a 2-quart dish gives you the best layers: think 8x8, 9x9, or 11x7 inch. A 9x13 will work, but it will be thinner and can bake faster, so keep an eye on it.
How do I make the mashed potatoes extra smooth?
Drain the potatoes well, then return them to the hot pot for 1 minute to steam off moisture. Mash first, then whip in warm milk and butter. If you want truly silky, use a potato ricer or food mill. Avoid a food processor, which can turn potatoes gluey.
My filling seems runny. What happened?
Usually it is one of two things: you did not simmer long enough after adding broth, or your heat was too low to thicken properly. Simmer until it looks glossy and coats a spoon. Also, let the baked pie rest 10 minutes so it can set.
Can I make it ahead?
Yes. Assemble, then let it cool briefly so it is not steaming hot, cover, and refrigerate up to 24 hours. Bake from cold at 375°F, adding 10 to 20 minutes depending on your dish depth, until it is bubbling and hot in the center.
What vegetables work best?
Peas and carrots are classic, but corn, green beans, chopped mushrooms, or chopped spinach all work. Just avoid watery veggies unless you cook off the moisture first.
Can I swap the beef?
Absolutely. Ground turkey, chicken, lamb, or a plant-based ground all work. If your protein is lean, add a touch more butter or olive oil for richness.
