Step‑by‑Step Instructions for Creamy Mustard Roasted Potatoes
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This temperature will ensure the perfect roast on your baby potatoes, creating tender insides and a delightful golden exterior. As the oven heats, gather your baking sheet and prepare to transform simple potatoes into creamy mustard roasted potatoes.
Step 2: Prepare the Potatoes
Next, spread the baby potatoes in a single layer on a baking sheet. Drizzle them generously with extra virgin olive oil, and sprinkle kosher salt and freshly cracked pepper for flavor. Toss the potatoes well, ensuring they are evenly coated, and prepare them for roasting in the oven.
Step 3: Roast the Potatoes
Place the baking sheet in the preheated oven and roast the potatoes for 35-40 minutes. Keep an eye on them, and when they become golden brown and fork-tender, they’re ready to be removed. This step is crucial for achieving the delicious, crispy texture that makes these creamy mustard roasted potatoes so satisfying.
Step 4: Sauté Aromatics
While the potatoes are roasting, heat a combination of butter and olive oil in a skillet over medium heat. Add the finely diced shallots and sauté for about 3-4 minutes until they soften and become translucent. Stir in minced garlic and sauté for an additional minute, releasing aromatic flavors into the oil, which will enhance the mustard cream sauce.
Step 5: Create the Mustard Sauce
Pour in your choice of chicken or vegetable broth into the skillet and bring it to a gentle simmer. Whisk in both Dijon mustard and grainy mustard, sprinkling in additional salt and pepper to taste. Allow the mixture to reduce slightly for a few minutes, melding the flavors together perfectly for your creamy mustard roasted potatoes.
Step 6: Thicken the Sauce
Add in the heavy cream, stirring to combine, and bring the sauce back to a simmer. To thicken, create a cornstarch slurry by mixing cornstarch with a little water, then pour it into the sauce while continuously stirring. Cook until the sauce thickens to a sumptuous consistency that will beautifully envelop the potatoes.
Step 7: Finish with Freshness
Once thickened, stir in the tangy lemon juice for a burst of brightness and adjust the seasoning as needed. This final touch will elevate your creamy mustard roasted potatoes, balancing the richness of the sauce while making the flavors pop.
Step 8: Serve and Garnish
In a serving bowl, layer the roasted potatoes and spoon the luscious mustard cream sauce over them. Repeat the layering to showcase that delectable sauce, and finish with a generous sprinkle of freshly chopped dill for a delightful herbaceous note. Enjoy your cozy comfort meal!
