Substitutions: While lamb is traditional, ground beef is a popular swap. You can also use ground turkey or chicken for a lighter version of this dish.
Vegetable Variations: Feel free to experiment with vegetables. Swap out the peas and carrots for your favorite veggies like green beans, mushrooms, or even diced sweet potatoes.
Make It Ahead: Shepherd’s pie can be prepared a day in advance. Assemble it completely, cover it with foil, and refrigerate. When you’re ready to bake, just pop it in the oven (you may need to add a few extra minutes of baking time).
Cheese Lovers: If you adore cheese, go ahead and add some to the mashed potatoes or even sprinkle some on top for a golden, bubbly finish.
Gluten-Free Option: If you need to make this gluten-free, simply replace the flour with cornstarch or a gluten-free flour blend.
