Ingredients

• 1½ lbs (700 g) ground beef (80/20)
• ½ cup (60 g) breadcrumbs
• 1 large egg
• 1 small onion, finely chopped (about 75 g), divided
• 2 cloves garlic, minced
• 1 tsp Worcestershire sauce
• 1 tsp Dijon mustard
• 1 tsp salt
• ½ tsp black pepper
• 2 tbsp olive oil (for searing)
• 2 cups (480 ml) beef gravy (store-bought or homemade)
• ½ cup (120 ml) heavy cream or whole milk (optional)
• 2 cups (200 g) shredded cheddar or mozzarella (plus extra for topping)
• 2 tbsp chopped fresh parsley (optional, for garnish)

Instructions

1. Preheat: Oven to 375°F (190°C). Grease a 9×13-inch (23×33 cm) baking dish.
2. Make the patties: In a bowl, combine ground beef, breadcrumbs, egg, half the onion, garlic, Worcestershire sauce, Dijon, salt and pepper. Mix gently—don’t overwork.
3. Form patties: Divide into 8 equal portions and form flattened patties. (Optional: press a small well in center for extra cheese.)
4. Sear: Heat oil in a skillet over medium-high heat. Sear patties 1–2 minutes per side until browned. Transfer to the baking dish.
5. Make gravy: In the same skillet sauté remaining onion 2–3 minutes, then add beef gravy and cream (if using). Bring to a simmer and scrape browned bits.
6. Assemble: Pour gravy over the patties, sprinkle shredded cheese evenly over the top.
7. Bake: Bake 25–30 minutes until cooked through and cheese is melted. Broil 1–2 minutes for browned top if desired.
8. Rest & serve: Let rest 5 minutes. Garnish with parsley and serve with mashed potatoes, rice or bread.
