- 2 cloves garlic, minced
- 1 cup frozen mixed vegetables (peas, carrots, corn)
- 2 tbsp tomato paste
- 1 cup beef broth
- 1 tsp Worcestershire sauce
- Salt and pepper to taste

- Transfer the savory filling to a casserole dish, evenly spreading it out.
- Scoop the prepared mashed potatoes on top, smoothing them to create an even layer. Dot the surface with small pats of butter and sprinkle cheese over the top if desired.

Best Ways to Enjoy It
When it comes to serving your Shepherd’s Pie Casserole, bringing it straight from the oven to the table can create a wonderful dining experience. Pair it with a simple side salad for a refreshing contrast, or serve with crusty bread to soak up the delicious filling. It can also work perfectly alongside steamed green beans or a light vegetable medley for a balanced meal.
Storage and Reheating Tips
Leftovers are a delight! Store any extra casserole in an airtight container in the refrigerator, where it will keep for up to 3-4 days. For longer storage, consider freezing it; just be sure to wrap it tightly in plastic wrap and aluminum foil to prevent freezer burn. When you’re ready to enjoy it again, you can reheat portions in the microwave or bake the whole dish at 350°F (175°C) until heated through.

For a perfect Shepherd’s Pie Casserole, consider these pro tips:
- Use homemade mashed potatoes for the best texture, but store-bought works well too if you’re short on time.
