Golden, buttery puff pastry wrapped around savory beef, deeply caramelized onions, and rich gravy. A comforting, elegant dish perfect for cozy dinners.

Ingredients

A. Caramelized Onion & Beef Filling

1 lb (450g) ground beef
3 large onions, thinly sliced
2 tbsp butter
1 tbsp olive oil
3 cloves garlic, minced
1 tbsp Worcestershire sauce
1 tsp thyme
1/2 tsp black pepper
1/2 tsp salt
2 tbsp flour
1 cup beef broth
1 tbsp tomato paste (optional)

B. Pastry Assembly

1 sheet puff pastry, thawed
1 egg (for egg wash)
Sesame seeds (optional)

Instructions

Caramelize the Onions:
Heat butter and olive oil in a large skillet over medium heat. Add onions and cook slowly for 18–25 minutes, stirring often, until soft, golden, and caramelized.
Cook the Beef:
Add ground beef to the onions and cook until browned. Add garlic, salt, pepper, and thyme. Cook 1 minute to release aroma.
Make the Gravy:
Sprinkle flour over the mixture and stir to coat. Add Worcestershire sauce and tomato paste. Pour in beef broth and simmer 5–7 minutes until thick and glossy. Let filling cool slightly.
Assemble the Pie:
Preheat oven to 400°F (200°C). Place puff pastry on a parchment-lined baking sheet. Spoon filling into the center and shape into a rectangle, leaving space around the edges. Fold edges slightly over the filling or leave open for a rustic look. Brush pastry with egg wash and sprinkle with sesame seeds if desired.
Bake:
Bake 22–28 minutes, or until puff pastry is puffed, crisp, and golden. Let rest 5 minutes before slicing.

Tips

Cool filling before adding to the pastry to prevent sogginess.
A splash of balsamic vinegar enhances onion sweetness.
For added heat, mix in chili flakes or diced jalapeños.
For a fully enclosed pie, use two pastry sheets.

Serving Ideas

Serve with mashed potatoes, roasted vegetables, green beans, or a light salad. A drizzle of gravy or balsamic glaze pairs well with the rich flavors.
