What you’ll need

To create this flavorful casserole, gather the following ingredients:

  • 1 cup beef broth
  • 1 teaspoon Worcestershire sauce
  • Salt and pepper to taste
  • 3 cups mashed potatoes (prepared from about 3 large potatoes)
  • 2 tablespoons butter

Feel free to substitute ground turkey or chicken for the beef if you’re looking for a lighter option. You can also use fresh vegetables if you prefer, but frozen ones are a quick and easy choice.

  9. Allow the casserole to cool for 5 minutes before serving.

Best ways to enjoy it

This Shepherd’s pie casserole is best enjoyed fresh from the oven, but it pairs wonderfully with a simple side salad, crusty bread, or even steamed green beans for an extra touch of color and nutrition. If you’re feeling adventurous, a dollop of sour cream or a drizzle of barbecue sauce can add an exciting twist to each bite!

Storage and reheating tips

Once you’ve made this delicious casserole, you might have leftovers! Store any uneaten portions in an airtight container in the refrigerator for up to 3 days. To reheat, simply place it in the oven at 350°F (175°C) until heated through, or pop individual portions in the microwave for a quick meal. You can also freeze the casserole before baking it for up to 3 months; just let it cool completely and wrap it well.

Helpful cooking tips

To enhance the flavors, consider sautéing the onions and garlic longer for a deeper caramelization. If you’re short on time, you can use store-bought mashed potatoes or even frozen mashed potatoes to save on prep. And don’t skimp on the seasoning—this dish shines with just the right amount of salt and pepper.

Creative twists

Looking to switch things up? Try adding different vegetables, like spinach or mushrooms, or using a different protein like shredded chicken or lentils for a vegetarian option. For a touch of elegance, consider topping the mashed potatoes with fresh herbs like thyme or rosemary before baking.
