Ingredients
For the Steak:
- 2 boneless beef steaks (ribeye, strip steak, or sirloin), about 8 ounces each
- Salt and black pepper, to taste
- 1 teaspoon garlic powder
- 1 tablespoon olive oil
- 1 tablespoon unsalted butter
For the Creamy Mustard Sauce:
- 1 tablespoon unsalted butter
- 2 cloves garlic, minced
- 1 teaspoon Dijon mustard
- 1 teaspoon whole grain mustard
- 3/4 cup heavy cream
- 1/2 cup beef broth
- 1/4 teaspoon dried thyme
- 1 tablespoon fresh dill or parsley, chopped
- Freshly cracked black pepper, to taste
For the Sides:
- 12 ounces baby potatoes
- 1 tablespoon olive oil
- Salt and black pepper, to taste
- 1/2 teaspoon garlic powder
- 8 ounces green beans, trimmed
- 1 teaspoon butter
Instructions
1. Roast the Potatoes
Preheat your oven to 425°F (220°C). Toss the baby potatoes in a bowl with olive oil, salt, black pepper, and garlic powder until they’re evenly coated. Spread them out on a baking sheet in a single layer. Roast for 25-30 minutes, shaking the pan halfway through, until they’re golden and tender. The crispy edges will make each bite irresistible!
2. Cook the Green Beans
While the potatoes are roasting, bring a small pot of salted water to a boil. Add the green beans and cook for 3-4 minutes until they’re crisp-tender. Drain them and toss with 1 teaspoon butter and a pinch of salt. Set them aside, keeping them warm and ready to serve.
3. Season the Steaks
Pat the steaks dry with paper towels (this helps them sear beautifully). Season both sides generously with salt, black pepper, and garlic powder. This will add flavor to the outside while keeping the steak tender on the inside.
4. Sear the Steaks
Heat the olive oil and 1 tablespoon of butter in a skillet over medium-high heat. Once the pan is hot, add the steaks and cook for 3-5 minutes per side, depending on the thickness of your steaks and your preferred level of doneness. After searing, remove the steaks from the skillet and transfer them to a plate. Let them rest for a few minutes while you make the sauce.
5. Make the Sauce Base
In the same skillet, reduce the heat to medium. Add 1 tablespoon of butter and the minced garlic. Let it cook for about 30 seconds, until the garlic becomes fragrant, filling your kitchen with a wonderful aroma.
6. Prepare the Creamy Mustard Sauce
Stir in the Dijon mustard, whole grain mustard, beef broth, heavy cream, and dried thyme. Let it simmer for 3-4 minutes, stirring occasionally, until the sauce thickens slightly. You’ll notice the sauce turning a beautiful golden color, ready to coat the steaks.
7. Finish the Sauce
Add the fresh dill or parsley and a few cracks of black pepper. Taste and adjust the seasoning if needed. The sauce should have a rich, tangy flavor with just a touch of creaminess to balance it all out.
8. Serve
Slice the steaks against the grain and arrange them on plates. Spoon the creamy mustard sauce generously over the top. Serve alongside the roasted baby potatoes and green beans. You’ll have a plate full of perfectly balanced flavors, each bite better than the last.
Presentation
For a beautiful presentation, arrange the sliced steaks on a plate with the sauce drizzled over them. Place the roasted potatoes and green beans around the steak, and garnish with a sprinkle of fresh dill or parsley to brighten up the dish. The golden potatoes and vibrant green beans will contrast beautifully with the rich sauce and deep color of the steak, making for a meal that looks as good as it tastes.
