PREPARATION:
Preheat your oven to a solid 400°F.
Boil the potatoes in a pot until they’re soft. Post draining, introduce milk, butter, and your seasonings. Mash these until you get a smooth texture.
Moving to a skillet, brown the beef over a medium flame. Introduce the garlic and onion and sauté until the onions are translucent.
Mix in your frozen veggies and let them cook for about 5 minutes.
Evenly dust your skillet contents with flour, mixing continuously.
Blend in the beef stock and Worcestershire sauce, stirring until you have a thickened gravy.
Sprinkle in the thyme, giving it another couple of minutes of mixing.
Transfer this hearty beef filling to a baking dish.
Layer the beef with your creamy mashed potatoes.
As a crowning glory, sprinkle the shredded cheddar atop.
Bake this for roughly 20-25 minutes, waiting for that golden-brown perfection on top.
Let it rest for a moment and then, dig in!
