Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Assemble the pie
In a meat pie dish, layer the sliced roast meat, wet it with gravy, and season with salt and pepper.
If desired, sprinkle chopped onion over the meat.
Pour stewed tomatoes over the meat and add more pepper.
Top with a thick layer of mashed potatoes.
Bake
Bake until the top is light brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Roast meat
- Forms the main filling and provides savory, meaty flavor.
- Gravy
- Adds moisture so the meat stays juicy during baking.
- Stewed tomatoes
- Contributes acidity and moisture to the filling.
- Mashed potatoes
- Forms a topping that browns in the oven and seals in moisture.
The step that matters
Top with a thick layer of mashed potatoes. A thick, even layer keeps the filling covered so it stays moist, and it gives the topping enough body to brown rather than dry out.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (beef, pepper, tomato, potato):
- Capsicumfits better
- Carrotfits about as well
- Onionthe original
- Okrafits about as well
Fit is the average pairing score against beef, pepper, tomato, potato. Candidates are from the same food group and used in at least 100 recipes.
