- 3 tbsp butter
- 2 large yellow onions, thinly sliced
- 1 tbsp all-purpose flour
- 1½ cups (360ml) beef broth
- ½ cup (120ml) dry red wine (optional; sub with more broth)
- 1 tsp thyme (fresh or dried)
- Pinch of sugar (to help caramelize onions)
For Topping:
- 4 slices baguette, toasted
- 1½ cups (6 oz) shredded Gruyère or Swiss cheese
💡 Pro Tips:
- Caramelize onions slowly—30+ minutes = deep, sweet flavor.
- Don’t skip the wine—it adds complexity (alcohol cooks off).
- Use freshly shredded cheese—pre-shredded won’t melt as smoothly.
Step-by-Step Instructions (Rich, Savory, Foolproof)
1. Make the Patties
- In a bowl, combine ground beef, breadcrumbs, egg, Worcestershire, Dijon, garlic powder, salt, and pepper.
- Mix gently; form into 4 oval patties.
- Sear in a skillet over medium-high heat: 3–4 minutes per side. Remove and set aside.
2. Caramelize the Onions
- In the same skillet, melt butter over medium-low heat.
- Add onions and pinch of sugar; cook 25–30 minutes, stirring occasionally, until deep golden brown.
- Stir in thyme; cook 1 minute.
3. Make the Gravy
- Sprinkle flour over onions; cook 1 minute.
- Gradually whisk in beef broth and wine. Simmer 5–7 minutes until thickened.
4. Assemble & Broil
- Return patties to skillet; nestle into gravy.
- Top each with a toasted baguette slice and Gruyère.
- Broil on high 2–3 minutes until cheese is bubbly and golden.

Make-Ahead & Storage Tips

- Not ideal for freezing—cheese and texture suffer.
