The gravy on those smothered pork chops — dark, thick, built from the fond left in the cast-iron after a hard sear — was the whole point. It was the thing Mama tasted and said nothing about, which meant everything. That same foundation, those same slow-cooked onions breaking down into something richer than they started, is what drives this French Onion-Beef Strudel. Different shape, different occasion, same truth: when you take your time with the onions, the rest of the dish knows it.
French Onion-Beef Strudel
Prep Time: 20 min | Cook Time: 40 min | Total Time: 1 hr | Servings: 6
Ingredients
- 1 lb ground beef (80/20)
- 2 large yellow onions, thinly sliced
- 2 tbsp unsalted butter
- 1 tsp granulated sugar
- 1 tsp Worcestershire sauce
- 1/2 cup beef broth
- 1 tsp fresh thyme leaves (or 1/2 tsp dried)
- 1/2 tsp garlic powder
- Salt and black pepper to taste
- 1 sheet frozen puff pastry, thawed
- 1 cup shredded Gruyère or Swiss cheese
- 1 large egg, beaten (for egg wash)
- 1 tsp flaky sea salt, for finishing
Instructions
- Caramelize the onions. Melt butter in a large skillet over medium-low heat. Add sliced onions and sugar. Cook, stirring occasionally, for 20–25 minutes until onions are deeply golden and soft. Don’t rush this step — the color is the flavor.
- Brown the beef. Push the onions to one side of the skillet and increase heat to medium-high. Add ground beef and cook, breaking it apart, until no pink remains, about 6–8 minutes. Drain excess fat.
- Build the filling. Combine beef and onions in the skillet. Add beef broth, Worcestershire sauce, thyme, and garlic powder. Stir and simmer over medium heat until the liquid reduces by half and the mixture is thick, about 5 minutes. Season generously with salt and pepper. Remove from heat and let cool 10 minutes.
- Assemble the strudel. Preheat oven to 400°F. On a lightly floured surface, unfold the puff pastry sheet. Spread the beef and onion filling lengthwise down the center third of the pastry, leaving a 1-inch border at each end. Scatter the shredded cheese evenly over the filling.
- Roll and seal. Fold the long sides of the pastry up and over the filling, overlapping in the center to seal. Pinch the ends closed and tuck them under. Transfer seam-side down onto a parchment-lined baking sheet.
- Egg wash and bake. Brush the entire surface of the strudel with beaten egg. Score the top lightly with a sharp knife in a diagonal pattern (do not cut all the way through). Sprinkle with flaky sea salt. Bake for 25–30 minutes until the pastry is deep golden brown and crisp.
- Rest and slice. Let the strudel rest on the baking sheet for 5 minutes before slicing. Cut into 6 portions with a serrated knife and serve warm.
