Elevate your next barbecue with succulent bone-in beef rib steaks grilled to perfection and served with a rich, velvety béarnaise sauce. This classic combination of smoky meat and buttery, tarragon-infused sauce creates a restaurant-quality dining experience at home.
Prepare your barbecue by lighting the coals; you want them to be glowing hot and covered in a light layer of grey ash before you start cooking.
Clarify the butter for the sauce: Melt the unsalted butter in a small saucepan over very low heat. Once melted, skim off any white foam from the surface. Carefully pour the clear yellow liquid (the clarified butter) into a bowl, leaving the milky solids at the bottom of the pan to be discarded.
Prepare the flavor reduction: In a separate small saucepan, combine the chopped tarragon, finely chopped shallots, white wine vinegar, 1 tablespoon of water, and 1/2 teaspoon of black pepper. Boil the mixture rapidly until the liquid has reduced to approximately 1 tablespoon, then set aside.
Make the sauce base: Place the egg yolks and 1 tablespoon of water in a heatproof bowl. Set the bowl over a pan of gently simmering water, ensuring the bottom of the bowl does not touch the water. Whisk vigorously until the mixture becomes thick, pale, and voluminous.
Emulsify the béarnaise: Remove the bowl from the heat. While whisking constantly, gradually pour in the warm clarified butter in a slow, steady stream until the sauce is thick and creamy. Stir in the tarragon and shallot reduction, season with salt to taste, and keep the sauce warm in a serving bowl in a low oven.
Grill the beef: Season the rib steaks generously with salt and pepper on both sides. Place on the hot barbecue and grill for 9–10 minutes per side for rare (internal temperature of 55°C) or 11–13 minutes per side for medium-rare (60–65°C).
Rest and serve: Remove the steaks from the grill and let them rest for 10 minutes to allow the juices to redistribute. To serve, cut the meat away from the bone and carve into thin slices. Serve immediately with the warm béarnaise sauce and your choice of sides.
For a perfectly emulsified béarnaise, ensure your clarified butter is warm but not boiling hot when adding it to the egg yolks. If the sauce begins to separate, whisk in a teaspoon of cold water to bring it back together. Always rest your steaks; it is the secret to tender, juicy meat.
