Ingredients
Method
- In an oven-safe skillet over medium-high heat, cook ground beef until no pink remains, about 5 minutes. Drain all but 1 tbsp fat (add oil if lean). Add onion, cook 4 minutes, then garlic for 30 seconds.
- Sprinkle flour blend over beef, stir 1 minute. Add tomato paste, cook 1 minute. Pour in broth and Worcestershire, scraping pan. Add thyme, salt, pepper. Simmer until thickened, about 5 minutes. Fold in peas and carrots, remove from heat.
- Boil potatoes in salted water until tender, 12–15 minutes. Drain, steam dry 1 minute. Mash with butter, warm milk, and salt. Stir in egg yolk if using, until creamy.
- Preheat oven to 400°F (200°C). Spread filling in a 9-inch square dish, top with potatoes, seal edges, and drag fork for ridges. Bake 25–30 minutes until bubbly.
- Broil on high, 6 inches from heat, 2–4 minutes until golden. Rest 10 minutes before serving.
Notes
Letting the pie rest for 10 minutes after baking helps the filling set so it doesn’t run when you scoop. If you skip the egg yolk, the topping will still be creamy but slightly less rich.
