How to Make Sirloin and Mustard Shallot Cream Sauce
-
Preheat the oven: Start by preheating your oven to 450 °F (232 °C) to ensure it’s hot and ready for roasting those delicious potatoes!
-
Prepare the potatoes: Cut the Yukon Gold potatoes into ½-inch wedges. Toss them with olive oil, salt, and your fry seasoning before placing them on a baking sheet. Roast for about 10 minutes, just until they start to turn golden.
-
Add vegetables: While the potatoes are getting crispy, wash the carrots and green beans. After the potatoes have roasted for 10 minutes, add your veggies to the baking sheet. Continue roasting everything together until the potatoes are crispy and vegetables are tender another 10-15 minutes will do!
-
Toast the almonds: In a small skillet over medium heat, toast the almonds until lightly golden, stirring occasionally to prevent burning. Once toasted, add the sugar and stir until it caramelizes, then set aside.
-
Cook the steak: In a hot skillet, add olive oil and let it heat. Sear the sirloin steak for about 3-4 minutes on each side until a crust forms. After cooking, let it rest for 5 minutes to retain those tasty juices.
-
Make the cream sauce: In the same skillet, saut the chopped shallots until soft and translucent. Then, stir in the beef stock concentrate and sour cream, allowing the mixture to simmer and thicken for about 2-3 minutes. Add the Dijon mustard and Herbes de Provence, stirring to combine.
-
Slice and serve: Slice the rested steak against the grain and plate it up with the roasted potatoes and vibrant vegetables. Drizzle that luscious mustard-shallot cream sauce over the top and finish with the toasted almonds for that delightful crunch.
Optional: Garnish with fresh herbs like parsley for an extra pop of flavor.

The vegetables can also be washed and prepped 1-2 days ahead; just keep them in an airtight container. When you’re ready to serve, roast the potatoes and veggies together for around 20-25 minutes. Sear and rest the steak just before serving, then whip up the sauce in a flash with ingredients heated on the stove. By prepping ahead, you ensure a delightful, hassle-free dining experience that s just as delicious!
