Seasoned minced beef is cooked down into a rich filling, then topped with mashed potato and finished under the broiler until lightly golden — a streamlined take on classic Irish comfort food. Using a skillet keeps prep and cleanup minimal, and the whole dish is ready in roughly 30 minutes. It's hearty, filling, and straightforward on a weeknight.
Heat the olive oil in a large pan over medium heat. Add the chopped onions and sauté until they turn translucent, about 3 minutes.
Add the minced garlic and continue to sauté for another minute until fragrant.
Increase the heat to medium-high and crumble in the minced beef. Cook, stirring occasionally, until it browns evenly, about 5 minutes.
Stir in the tomato paste and thyme, cooking for an additional minute to meld the flavors.
Pour in the beef stock and bring to a simmer. Reduce the heat and let it cook for about 10 minutes, or until the liquid slightly reduces.
Meanwhile, in a separate pot, boil the potato cubes in salted water until tender, approximately 10 minutes. Drain and return to the pot.
Add butter and milk to the potatoes and mash until smooth. Season with salt and pepper to taste.
Preheat the oven's grill (broiler) to high. Spoon the beef mixture into an ovenproof dish and top with the mashed potatoes, spreading evenly.
Place the dish under the grill for 5 minutes, or until the potato peaks turn golden brown and crisp.
Notes
For an extra depth of flavor, consider adding a splash of Worcestershire sauce to the beef mixture. Substitute minced turkey for a lighter version. Ensure to season the mashed potatoes adequately to enhance their creamy flavor.
