Can I make Easy Shepherd's Pie Casserole ahead of time?

Yes. Assemble the casserole and refrigerate for up to 24 hours before baking. Bring it to room temperature for 20 minutes before baking.

Can I use pre-made mashed potatoes?

Absolutely. Use store-bought or instant mashed potatoes for speed. Warm them slightly before spreading to avoid chilling the filling.

Use gluten-free beef broth and check Worcestershire sauce for gluten. If you need a thicker filling, use cornstarch instead of wheat flour.

Preheat oven to 400°F (200°C).
In a large skillet, cook ground beef over medium heat until browned; drain excess fat.
Add chopped onion and minced garlic to the skillet; cook until softened, about 3-4 minutes.
Stir in frozen mixed vegetables, tomato paste, beef broth, Worcestershire sauce, salt, and pepper.
Simmer the mixture for 5-7 minutes until slightly thickened.
Transfer the beef mixture to a casserole dish, spreading evenly.
Top with prepared mashed potatoes, spreading to cover the filling completely.
Dot the mashed potatoes with butter and sprinkle with shredded cheddar cheese if using.
Bake in the preheated oven for 20-30 minutes until the top is golden and bubbly.
Let cool for 5 minutes before serving.

For perfect results, use warm mashed potatoes so they spread easily. If you make potatoes ahead, warm them gently with a splash of milk.
