Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
4 cups leftover meatloaf, crumbled
3 cups leftover mashed potatoes
1 bag (12 ounces) frozen mixed vegetables, such as carrots, peas, corn, and green beans
2 teaspoons olive oil
Directions
Preheat the oven to 350°F.
Heat the olive oil in a large skillet over medium-high heat.
Add the crumbled leftover meatloaf and the frozen mixed vegetables to the skillet.
Break up the meatloaf with a spoon and cook everything together for 5 to 8 minutes, stirring occasionally, until the vegetables are heated and the mixture is well combined.
Transfer the meat and vegetable mixture to a medium baking dish and spread it into an even layer.
Spoon the mashed potatoes over the top and gently spread them to cover the filling completely.
Bake for 20 to 25 minutes, or until the filling is hot and the mashed potatoes are lightly golden around the edges.
You can easily adjust this dish based on what you have in the kitchen. Swap the mixed vegetables for peas and carrots, corn, or chopped green beans. Add a little shredded cheddar to the mashed potato topping for extra richness. For a more savory filling, stir in a spoonful of gravy or a splash of broth while warming the meatloaf mixture. You can also bake the casserole in individual ramekins for single-serving portions.
Storage/Reheating
Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place a portion in the microwave and heat until warmed through, or reheat the casserole in a 350°F oven for about 15 to 20 minutes. If reheating in the oven, covering it loosely with foil helps keep the filling from drying out while the center warms.
