Ingredients
Directions
Prepare the potatoes
Prepare instant potatoes according to the package.
Peel whole potatoes and cut them into 1" cubes.
Boil the cubes until ready to mash.
Mash the potatoes until soft and the cubes crumble when poked with a fork.
Add salt, butter, and milk to the mashed potatoes.
Add pepper and garlic powder to the potatoes.
Make the beef layer
Brown the ground beef over medium heat in a large frying pan.
Drain most of the fat from the browned beef.
Mix flour and cold water in an 8‑ounce cup until blended.
Stir the flour mixture into the drained beef over low heat, coating evenly.
Assemble and bake
Spread the beef mixture evenly in a 9" glass casserole dish or cake pan.
Drain the corn or peas and layer them on top of the beef.
Spread the mashed potatoes over the pea layer.
Sprinkle cheese on top, if desired.
Cook in a microwave on high for 5 minutes or bake at 350°F for 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ground beef
- Forms the savoury, meaty base layer of the pie.
- Potatoes
- Form the mashed topping, giving a soft, fluffy crust when cooked.
- All-purpose flour
- Thickens the drained meat juices so the beef layer holds together.
- Butter or margarine
- Adds fat and richness to the mashed potatoes.
- Milk
- Adds moisture and softness to the mashed potatoes.
- Cheddar or parmesan cheese
- Melts over the top and adds savoury flavour and light browning.
The step that matters
Stirring the flour mixture into the beef. Flour must be fully blended in cold water first and stirred over low heat so it thickens evenly without lumps, keeping the beef layer from becoming watery under the potatoes.
