Prepare the Beef Mixture
In a non-stick pan, cook the onions over medium heat until soft. Add garlic and cook for 1 minute more. Add the lean mince and brown it thoroughly. -

Assemble the Casserole

Top with Cheese

Bake
Bake in the oven for 20 minutes or until the top is golden and bubbling. Let cool slightly before serving.

🥘 Step-by-Step Cooking Guide
🥔 Make the Mash
- Boil chopped potatoes in a pot of water with a veg stock cube.
- Once soft, drain and mash with fat-free Greek yogurt.
- Mash until smooth and season to taste.
Tip: Don’t add butter or cream—Greek yogurt adds creaminess without extra fat.

- Sauté onions in a dry non-stick pan or with a spray of low-calorie cooking spray.
- Add garlic, then beef. Cook until no pink remains.
- Stir in tomato purée, chopped tomatoes, herbs, Worcestershire sauce, and beef stock.
- Let it simmer uncovered to reduce slightly and develop rich flavour.
Tip: If it looks too watery, simmer longer or stir in 1 tsp of cornflour dissolved in water.
🧀 Layer & Bake
- Layer mash and beef alternately in a baking dish.
- Finish with a generous sprinkle of reduced-fat cheese.
- Bake until bubbling and golden.
Tip: Use a glass or ceramic dish so the golden layers show beautifully.
