Quick and Easy Shepherd's Pie uses instant mashed potatoes, seasoned ground beef, mixed vegetables, tomato soup, and cheddar to build a practical 9×13-inch casserole. The shortcuts keep preparation manageable while preserving the familiar layers of savory filling, creamy potatoes, and browned cheese.
The recipe makes one large casserole, or 8 servings, in 50 minutes: 20 minutes of preparation and 30 minutes of cooking. Bake uncovered at 400°F, then wait 5–10 minutes before cutting so the hot layers settle.
Quick Shepherd's Pie Ingredients
For the topping, use about ½ of a 13-ounce box instant mashed potatoes, or more if you prefer extra potatoes. Prepare them with butter, milk, and salt in the amounts required by that package's directions.
The filling needs 1 pound ground beef, one 12-ounce bag frozen mixed vegetables, one 10.75-ounce can tomato soup, one 1.5-ounce packet beef stew seasoning, and ½ cup water. Finish with 1–2 cups shredded cheddar.
