Step‑by‑Step Instructions for Creamy Mustard Roasted Potatoes
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). While the oven warms up, prepare a large baking sheet by lightly greasing it with a bit of olive oil. This will ensure your potatoes get that crispy, golden finish.
Step 2: Prepare the Potatoes
In a spacious mixing bowl, toss the baby potatoes with extra virgin olive oil, kosher salt, and freshly cracked pepper until they are evenly coated. Spread the seasoned potatoes in a single layer on your prepared baking sheet to ensure they roast evenly, enhancing the flavor and texture of your Creamy Mustard Roasted Potatoes.
Step 3: Roast the Potatoes
Place the baking sheet in the preheated oven and roast the potatoes for 35-40 minutes. Halfway through, give them a gentle stir to promote even browning. They are ready when they are tender and golden brown, with crispy edges begging to be paired with that creamy mustard sauce.
Step 4: Sauté Shallots
While the potatoes are roasting, heat a skillet over medium heat and add butter along with a drizzle of olive oil. Once melted, add diced shallots and sauté for about 3-4 minutes, or until they become soft and translucent. This step builds a flavorful base for the creamy sauce that will elevate the dish.
Step 5: Add Garlic
Next, stir in minced garlic and continue sautéing for an additional minute. The aroma of garlic will fill your kitchen, adding an irresistible layer of flavor. Make sure to stir frequently to avoid burning, as the garlic can turn bitter quickly.
Step 6: Simmer the Broth
Pour in chicken or vegetable broth and bring the mixture to a gentle simmer over medium heat. Once simmering, whisk in both Dijon and grainy mustard, along with a sprinkle of salt and pepper. This will form a tangy, luscious sauce that complements your roasted potatoes beautifully.
Step 7: Thicken the Sauce
After simmering for about 5-7 minutes, allow the broth to reduce by about one-third. Then, slowly stir in heavy cream, bringing the mixture back to a simmer. This adds the rich, creamy texture crucial for your Creamy Mustard Roasted Potatoes’ sauce.
Step 8: Create a Slurry
In a small bowl, combine cornstarch and water to create a slurry. Whisk this mixture into the simmering sauce, stirring continuously until it thickens, about 2-3 minutes. This step ensures your sauce clings beautifully to each potato, creating that comforting feel we all love.
Step 9: Add Final Touches
Finish your sauce by stirring in fresh lemon juice, adjusting seasoning according to taste. This brightens the flavors of the sauce, making it even more delightful. It’s time to bring together all the components of your Creamy Mustard Roasted Potatoes.
Step 10: Serve and Enjoy
Layer the roasted potatoes in a beautiful serving dish, pouring the creamy mustard sauce generously over the top. Optionally, sprinkle with freshly chopped dill for an extra burst of flavor. You can repeat layers for a more decadent presentation or serve immediately as a cozy side dish.
