Preparation
- French Onion Sauce: Melt butter in large skillet set over medium-low heat. Add onions and cook, stirring frequently for 20 to 25 minutes, or until deep golden brown and tender.
- Stir in tomato paste; cook for 1 minute. Sprinkle flour over onions. Cook, stirring for an additional minute, or until onions are evenly coated.
- Deglaze pan with brandy; reduce by half. Pour in wine; simmer until slightly reduced.
- Whisk beef stock with demi-glace and Dijon mustard; stir into pan. Simmer until sauce is smooth, thickened and reduced to 8 cups (2 L). Season with salt and pepper. Cool, cover and refrigerate or hold for service.
- Cheesy Garlic Toast: Beat butter with garlic, olive oil, garlic powder, salt and pepper. Spread evenly on one side of each baguette slice. Arrange on parchment paper-lined sheet pan in single layer.
- Toss mozzarella with Swiss, parsley and thyme. Sprinkle evenly over bread. Cover and refrigerate.
Service
- Season steak with salt and pepper. Heat 2 tbsp (30 mL) oil in skillet set over medium-high heat. Sear steak on both sides.
- Add 2 tbsp (30 mL) butter, 2 sprigs thyme and 2 cloves garlic. Cook, basting with fat, until evenly browned and cooked to preferred doneness. Let rest for 5 minutes before slicing across the grain.
- Meanwhile, bake 2 slices of Cheesy Garlic Toast until bread is golden brown around the edges and cheese is melted.
- Plate steak with ½ cup (125 mL) French Onion Sauce (warmed) and Cheesy Garlic Toast.
Chef's Tip
If the pan gets dry while caramelizing onions, add a splash of water to prevent scorching.
Pinot Noir or Cabernet Sauvignon are good choices for the French Onion Sauce. Serve with choice of classic steakhouse sides, such as house-cut fries, baked potato, roasted tomato halves, Caesar salad, sautéed mushrooms or creamed spinach.
