Delicious Cottage Pie with Lean Mince and Creamy Mash

Instructions:

1. Heat a large nonstick pan with cooking spray over high heat.
2. Add the ground beef and cook for 8-10 minutes or until browned, breaking up any clumps. Drain any fat and set aside.
3. Reduce heat to medium and add the onion, carrot, celery, garlic, and 2 tablespoons of water to the pan.
4. Cook for 10 minutes, adding a little more water if necessary to prevent sticking.
5. Return the ground beef to the pan and add the bouillon cube, tomato paste, Worcestershire sauce, thyme, Marmite (if using), and 400ml of boiling water.
6. Bring to a simmer and cook for 20 minutes or until the sauce thickens, stirring occasionally. Adjust seasonings to taste.
7. While the sauce simmers, prepare the topping. Boil the potatoes and parsnips in a pot of salted water until tender, about 15 minutes.
8. Preheat your oven to 200°C (fan 180°C/gas 6).
9. Spoon the ground beef mixture into an ovenproof dish. Mash the drained potatoes and parsnips, and season with salt and pepper.
10. Top the beef mixture with the mash and smooth the surface with a fork.
11. Bake in the oven for 25 minutes. Serve hot with your favorite vegetables.
