6 servings · 30 minutes preparation · 50 minutes cooking · 15 minutes cooling, chilling or resting

Ingredients

• 1.5 pounds halal ground beef (85% lean) (use halal-certified ingredients)
• 2.5 pounds Yukon Gold potatoes, peeled and cut into 1-inch chunks
• 4 tablespoons unsalted halal-certified butter, divided
• 0.5 cup whole milk, warmed
• 1 cup grated sharp cheddar cheese (made with microbial/halal rennet) (use halal-certified cheese with suitable rennet)
• 1 large yellow onion, finely diced
• 2 medium carrots, peeled and diced into 0.25-inch cubes
• 2 ribs celery, finely diced
• 3 cloves garlic, minced
• 2 tablespoons all-purpose flour
• 2 tablespoons halal-certified tomato paste
• 1.5 cups halal-certified beef broth
• 1 tablespoon halal-certified Worcestershire-style sauce (anchovy-based, alcohol-free)
• 1 teaspoon fresh thyme leaves, chopped
• 1 cup frozen sweet green peas, thawed
• 1.5 teaspoons fine sea salt, divided
• 0.5 teaspoon freshly ground black pepper

Step-by-step instructions

1. Place the peeled Yukon Gold potato chunks into a large pot, cover with cold water, add 1 teaspoon fine sea salt, bring to a boil over high heat, and cook for 15 to 18 minutes until completely tender when pierced with a fork.
2. Drain the potatoes thoroughly in a colander, return them to the warm dry pot, and mash until smooth with 3 tablespoons halal-certified butter, 0.5 cup warmed whole milk, and 0.25 teaspoon black pepper; set aside.
3. In a deep 12-inch oven-safe skillet or Dutch oven, heat 1 tablespoon butter over medium heat, add 1.5 pounds halal ground beef, and cook for 6 to 8 minutes, breaking it into small crumbles until browned.
4. Add the diced onion, carrots, and celery to the beef; cook for 6 to 7 minutes until the vegetables soften.
5. Stir in the minced garlic, 2 tablespoons tomato paste, and chopped fresh thyme; cook for 2 minutes while stirring constantly.
6. Sprinkle 2 tablespoons all-purpose flour over the meat mixture and stir continuously for 1 minute to coat and cook the raw flour taste.
7. Pour in 1.5 cups halal beef broth and 1 tablespoon alcohol-free Worcestershire sauce, scraping up any browned bits from the pan bottom; simmer over medium-low heat for 8 to 10 minutes until the gravy thickens into a glossy sauce.
8. Stir in 1 cup thawed green peas, the remaining 0.5 teaspoon salt, and 0.25 teaspoon black pepper, then remove the skillet from heat (or transfer the filling to a 9x13-inch baking dish).
9. Preheat the oven to 400°F (204°C); spoon the warm mashed potatoes over the beef filling, spread evenly with a spatula, use the tines of a fork to create textured ridges across the top, sprinkle with 1 cup grated halal sharp cheddar cheese, bake at 400°F (204°C) for 20 minutes until bubbling, broil on high for 2 to 3 minutes to brown the cheese crust, and rest for 15 minutes before serving. Before serving, verify the center of the ground-meat filling or meatballs reaches at least 160 F (71 C) on a food thermometer; extend cooking as needed.

Kitchen notes

Creating ridges on the mashed potato topping with a fork is essential for achieving crisp golden peaks. Those small raised edges catch the direct heat under the broiler, developing deep flavor and textural contrast against the soft potato beneath. Make sure the beef gravy is thickened before topping with potatoes; a watery filling will boil up violently around the edges and dilute the mashed potato crust during baking.

Storage & make-ahead

Cool leftovers and refrigerate in an airtight container within 2 hours of baking. Store in the refrigerator for up to 3 days. Reheat individual portions in an oven preheated to 350°F (177°C) for 20 minutes until heated through to an internal temperature of 165°F (74°C). Reheating in an oven preserves the crisp cheddar topping much better than a microwave.
