Instructions:
1. Make the Mashed Potatoes
Boil potatoes in salted water until fork tender (about 15 minutes).
Drain and mash with butter, cream, salt, and pepper. Stir in cheddar if using. Set aside.
2. Cook the Filling:
Heat olive oil in a large skillet over medium heat.
Add onion and carrots and cook about 5 minutes until softened.
Add garlic and cook another 30 seconds.
3. Brown the Beef:
Add ground beef and cook until browned. Drain excess grease if needed.
4. Build the Sauce:
Stir in tomato paste and cook for 1 minute.
Sprinkle flour over the mixture and stir well.
Pour in Guinness and beef broth, stirring to combine.
Add Worcestershire sauce, thyme, rosemary, salt, and pepper.
Simmer about 8–10 minutes until thickened.
Stir in frozen peas.
5. Assemble the Pie:
Preheat oven to 400°F.
Spread beef mixture evenly in a baking dish.
Top with mashed potatoes, spreading evenly. Use a fork to create ridges for crispy edges.
6. Bake:

For extra color, broil for 2–3 minutes at the end.
Helpful Tips & Tricks:
- Let the filling cool slightly before topping with potatoes so they stay fluffy.

- A splash of balsamic vinegar deepens the gravy flavor.
- For extra richness, stir a tablespoon of butter into the beef mixture before baking.
