# How to Make It:
01 - Preheat the oven to 400°F (200°C).
02 - Boil peeled and chopped potatoes in salted water for 15 to 20 minutes until tender. Drain thoroughly.
03 - Mash potatoes with butter and milk until smooth and creamy. Season with salt and pepper. Stir in cheddar cheese if desired. Set aside.
04 - Heat olive oil in a large skillet over medium-high heat. Sauté chopped onions and diced carrots for 3 to 4 minutes until softened.
05 - Add minced garlic and cook for 1 minute. Incorporate ground beef or lamb and cook, breaking up meat until browned and cooked through. Drain excess fat if necessary.
06 - Stir in tomato paste, Worcestershire sauce, thyme, rosemary, salt, and pepper. Sprinkle flour over the mixture and stir to coat evenly.
07 - Pour in broth and simmer for 5 minutes until thickened. Add peas and corn, stir well, and cook an additional 2 to 3 minutes. Adjust seasoning as necessary.
08 - Transfer the meat filling evenly into a 9x13-inch (23x33 cm) baking dish.
09 - Spoon the mashed potatoes over the filling and spread smoothly to cover. Use a fork to create ridges for a crispier finish.
10 - Bake in the preheated oven for 25 to 30 minutes until the topping is golden and the filling bubbles.
11 - Allow the casserole to rest for 5 to 10 minutes before serving.
