Bistro Beef Tart Recipe French Onion Beef Mince Delight

Instructions:

1. Make the Dough: Combine flour and salt. Cut in butter until mixture resembles coarse crumbs. Gradually add ice water until dough comes together. Form into a disc, wrap in plastic wrap, and chill.
2. Caramelize the Onions: Heat olive oil in a large skillet over medium-low heat. Add onions and cook slowly, stirring occasionally, until deeply golden brown and caramelized. This takes time - be patient, like waiting for the next series of Bridgerton to drop.
3. Cook the Beef: Add ground beef to the skillet with the onions. Break it up and cook until browned. Drain any excess grease.
4. Add Flavors: Stir in garlic, thyme, salt, and pepper. Cook for 1 minute more.
5. Make the Sauce: Sprinkle flour over the beef mixture and cook for 1 minute. Gradually whisk in beef broth until slightly thickened. Stir in Dijon mustard. Remove from heat.
6. Assemble the Tart: Roll out the dough on a lightly floured surface to a 12-inch circle. Transfer to the tart pan, pressing into the bottom and up the sides. Trim excess dough and crimp edges.
7. Fill the Tart: Spread the beef and onion mixture evenly into the tart shell. Sprinkle with Gruyère cheese, if using.
8. Bake: Brush the edges of the tart with egg wash. Bake in a preheated oven at 400°F (200°C) for 35-45 minutes, or until the crust is golden brown and the filling is bubbling. Let cool slightly before slicing and serving.
