Ingredients

Instructions

1. 1Preheat the oven to 375 degrees F (190 degrees C).
2. 2Place olive oil and butter in a Dutch oven over medium heat. Stir in ground lamb and onion; cook and stir until meat is brown and crumbly, about 10 minutes.
3. 3Stir in flour until incorporated. Mix in garlic, ketchup, rosemary, paprika, cinnamon, salt, and pepper; cook and stir until garlic is fragrant, 2 to 3 minutes.
4. 4Stir in water, scraping up any brown bits from the bottom of the Dutch oven. Reduce heat to medium-low and bring mixture to a simmer; cook and stir until thick, 5 to 6 minutes.
5. 5Remove lamb mixture from heat, then stir in peas and carrots until combined.
6. 6Spread lamb mixture into the bottom of a 9x13-inch baking dish; set aside.
7. 7Place potatoes into a large pot of salted water. Bring to a boil, reduce heat to medium, and cook until tender, about 15 minutes. Drain well and return potatoes to the pot.
8. 8Mash Irish cheese, cream cheese, butter, and cayenne pepper into potatoes until smooth. Season with salt and black pepper.
9. 9Whisk together egg yolk and milk in a small bowl; stir into mashed potato mixture.
10. 10Top lamb mixture in the baking dish with mashed potatoes; spread evenly to cover.
11. 11Bake in the preheated oven until the top is golden brown and sauce is bubbling up around the edges, 25 to 30 minutes.
