Ingredients
Ingredients
- 2 bone-in striploin steaks
- Olive oil
- Kosher salt
Sides
- 1 ½ pounds fingerling potatoes
- 1 tablespoon Bomba sauce
- 2 tablespoons olive oil
- 16 asparagus ends trimmed
- Freshly ground pepper
Mushroom Cream Sauce
- 2 tablespoons butter
- 1 tablespoon olive oil
- 3 cloves garlic minced
- ½ cup beef broth no salt added
- ½ cup heavy cream
- 2 teaspoon Dijon mustard
- 1 teaspoon Worcestershire sauce
- ¼ teaspoon salt
- ½ teaspoon freshly cracked black pepper
- 1 teaspoon fresh thyme
- 1 tablespoon lemon juice
- ½ cup mascarpone
Instructions
Prepare the Steaks
- Remove the steak from the refrigerator and let it sit at room temperature for about 30 minutes.
Preheat the grill to medium-high.
- Drizzle the steak with olive oil, then generously season with Kosher salt. Repeat on the other side.
Bomba Potatoes
- Boil the fingerling potatoes for 11 minutes. When they are cool enough to handle, slice each potato on a diagonal into three pieces. Toss the potatoes with the Bomba Sauce. Heat a sauté pan or skillet with oil then toss in the potatoes until they are golden and crispy on the edges, about 5-7 minutes.
Grill the Steaks
- While the potatoes are cooking, sear the steaks over high heat, flipping the steaks halfway. Approximately 5 minutes or until the steak reaches an internal temperature of 124°F to 128°F, for medium rare. The internal temperature will continue to rise as the steak rests.
- Loosely tent the steaks to rest. While the steaks are resting make the mushroom sauce.
Mushroom Cream Sauce
- Melt the butter with the oil in a skillet over medium-high heat.
- Add the mushrooms and sauté for 3-4 minutes until they start to brown. Add the garlic and sauté for another minute.
- Pour in the beef broth, cream, Dijon mustard, Worcestershire sauce, salt, pepper, and thyme while continuing to stir. Cook for another 6-8 minutes until the liquid has reduced and the sauce becomes creamy.
- Lower the heat to keep warm.
- Just before serving add in the lemon juice and the mascarpone. Serve immediately.
Asparagus
- Drizzle with olive oil and sprinkle with salt and pepper. Grill the asparagus directly over high heat for a slight char and tender-crisp texture, about 3 minutes.
Serve
- Slice the steaks against the grain for maximum tenderness. Arrange the asparagus and potatoes neatly on the plate, then top with steak slices and generously spoon over the mushroom cream sauce. Garnish with fresh thyme, optional.

Notes
Recipe Tips:
- Quality of Meat: Choose high-quality, well-marbled striploin steaks for the best flavour and tenderness.
- Proper Seasoning: Generously season the steaks with kosher salt to enhance their natural flavours.
- Grill Temperature: Ensure your grill is preheated to medium-high before searing the steaks to achieve a perfect crust.
- Internal Temperature: Use a meat thermometer to check the steaks' internal temperature. For medium-rare, aim for 124°F to 128°F before resting.
- Resting the Meat: Let the steaks rest, tented loosely with foil, for about 5-10 minutes after grilling. This helps the juices redistribute, making the steak more tender and flavourful.
- Sauce Consistency: Cook the mushroom sauce until it reduces and thickens to a creamy consistency. Stir frequently to prevent it from sticking to the pan.
- Mascarpone Addition: Add the mascarpone cheese just before serving to ensure it melts smoothly into the sauce, providing a rich and creamy texture.
