  • 2 tbsp olive oil or vegetable oil

• To assemble:

  • 1 cup shredded cheddar cheese (for topping)

Instructions:

1. Make the mashed potatoes:

   • Boil the peeled and cubed potatoes in salted water until tender (about 15 minutes).

   • Drain and mash with butter and milk until smooth and creamy.

   • Stir in 1 cup shredded cheddar cheese.

   • Season with salt and pepper. Set aside.

2. Prepare the beef filling:

   • In a large skillet, heat oil over medium heat.

   • Add the chopped onion and garlic; sauté until translucent and fragrant (about 3-4 minutes).

   • Add ground beef, breaking it up with a spoon, and cook until browned and no longer pink.

   • Stir in peas and carrots if using.

   • Mix in tomato paste (or ketchup), Worcestershire sauce, thyme, salt, and pepper.

   • Pour in beef broth and let simmer for 5-7 minutes, until slightly thickened.

   • Taste and adjust seasoning.

3. Assemble the casserole:

   • Preheat oven to 375°F (190°C).

   • In a baking dish (about 9×13 inches), spread the beef mixture evenly.

   • Layer the cheesy mashed potatoes on top of the beef mixture, spreading it evenly.

   • Sprinkle extra shredded cheddar cheese on top.

4. Bake:

   • Bake uncovered for 20-25 minutes or until the top is golden and bubbly.

   • If you want an extra crispy top, you can broil for an additional 2-3 minutes (watch carefully to avoid burning).

5. Serve:

   • Let the casserole cool for a few minutes.

   • Garnish with chopped parsley or chives if desired.

   • Serve warm and enjoy!
