Step‑by‑Step Instructions for Creamy Mustard Roasted Potatoes
Step 1: Preheat and Prepare
Preheat your oven to 400°F (200°C) while you prepare the baby potatoes. Wash and dry them thoroughly, and then cut larger potatoes in half if needed for even roasting. On a baking sheet, drizzle the potatoes with extra virgin olive oil, season generously with kosher salt and pepper, and toss until coated. Spread them out evenly and roast for 35-40 minutes, or until they are tender and golden brown.
Step 2: Sauté Aromatics
In a skillet, heat a tablespoon of butter and a drizzle of olive oil over medium heat. Once melted and bubbling, add the diced shallots and sauté for about 3-4 minutes until they become soft and translucent. Next, stir in the minced garlic and sauté for another minute until fragrant, ensuring not to burn the garlic, as it will add a bitter taste to your creamy mustard roasted potatoes.
Step 3: Build the Sauce
Pour in the chicken or vegetable broth into the skillet with the sautéed shallots and garlic, bringing the mixture to a gentle simmer. Whisk in the Dijon and grainy mustards along with additional salt and pepper to taste. Allow the sauce to simmer for around 5-7 minutes, stirring occasionally, until it has reduced by about a third, intensifying the flavors of your creamy mustard roasted potatoes.
Step 4: Create the Creamy Base
After reducing, stir in the heavy cream, returning the sauce to a gentle simmer. This will give your sauce that rich, creamy texture that’s perfect for coating the potatoes. In a small bowl, mix cornstarch with water to create a slurry, then slowly whisk it into the sauce. Cook for another minute, keeping an eye on it as it thickens to the desired consistency.
Step 5: Finish and Serve
Once the sauce is thickened, squeeze in some fresh lemon juice to brighten the flavors. Taste again to adjust seasoning if necessary. To serve your delectable creamy mustard roasted potatoes, layer the tender potatoes in a bowl, generously drench them with the creamy mustard sauce, and sprinkle with fresh dill for a touch of color and flavor. Repeat this layering as desired for a comforting, hearty dish!

How to Store and Freeze Mustard Roasted Potatoes
Fridge: Store your creamy mustard roasted potatoes in an airtight container for up to 3 days. This helps maintain their creamy texture and flavor.
Freezer: For longer storage, freeze the cooled potatoes in an airtight container or freezer bag for up to 2 months. Thaw in the fridge before reheating.
Reheating: To preserve the texture, reheat in the oven at 350°F (175°C) for about 15 minutes. Alternatively, you can gently microwave them, but the oven method keeps them crispy.
Avoid Sogginess: If freezing, consider freezing the sauce separately to maintain the creamy consistency of your mustard roasted potatoes upon reheating.
Make Ahead Options
These Creamy Mustard Roasted Potatoes are a fantastic option for meal prep! You can roast the baby potatoes up to 3 days in advance; simply allow them to cool and store them in an airtight container in the refrigerator. For the mustard cream sauce, you can prepare it up to 24 hours ahead; just keep it refrigerated and reheat on the stove while whisking to maintain its creamy consistency. When you’re ready to serve, gently mix the sauce with the roasted potatoes until everything is warmed through — your dish will be just as delicious and comforting, saving you valuable time on busy weeknights!
