Step‑by‑Step Instructions for Creamy Mustard Roasted Potatoes
Step 1: Preheat the Oven
To kick off your journey to making Creamy Mustard Roasted Potatoes, preheat your oven to 400°F (200°C). This temperature ensures that the potatoes will roast beautifully, developing a golden exterior while becoming tender on the inside. As the oven warms up, you can prepare the potatoes, setting the stage for a delicious side dish.
Step 2: Prepare the Potatoes
Wash and dry 1 to 2 pounds of baby potatoes, mixing in red and yellow varieties for color. Place them on a large baking sheet, drizzle generously with extra virgin olive oil, and season with kosher salt and pepper. Toss them to coat evenly, making sure each potato is seasoned. Roast in the preheated oven for 35-40 minutes, or until they are golden brown and fork-tender.
Step 3: Sauté Aromatics
While the potatoes are roasting, melt 2 tablespoons of butter with 1 tablespoon of olive oil in a skillet over medium heat. Add a finely diced shallot and sauté for about 3-4 minutes until softened and translucent. Then, stir in 2 minced garlic cloves and sauté for one more minute, releasing a wonderful aromatic scent that will enhance your sauce.
Step 4: Create the Cream Sauce
Pour in 1 cup of chicken or vegetable broth into the skillet, bringing it to a gentle simmer. Whisk in 2 tablespoons of Dijon mustard and 1 tablespoon of grainy mustard, stirring until well combined. Season the mixture with kosher salt and pepper to taste, allowing it to simmer until the sauce reduces by about one-third, which should take another 5-7 minutes.
Step 5: Thicken the Sauce
Once the broth is reduced, reduce the heat and stir in 1 cup of heavy cream. Bring the mixture back to a simmer, enhancing its richness. Meanwhile, mix 1 tablespoon of cornstarch with 2 tablespoons of water to create a slurry. Whisk this slurry into the sauce to thicken it, cooking for an additional 2-3 minutes until it reaches your desired consistency.
Step 6: Final Touches and Serve
Finish your luscious cream sauce by adding a splash of freshly squeezed lemon juice, adjusting the seasoning as needed. When the potatoes are roasted to perfection, layer them in a serving bowl and drizzle the creamy mustard sauce over the top. Garnish with chopped fresh dill for a bright touch. Serve your Creamy Mustard Roasted Potatoes warm, and enjoy this comforting side at your winter gatherings!

Creamy Mustard Roasted Potatoes Recipe FAQs
How do I choose the best baby potatoes for this recipe?
Absolutely! When selecting baby potatoes, look for ones that are firm and smooth without dark spots or wrinkles. The ideal choices are a mix of yellow and red-skinned potatoes, which not only provide a beautiful color contrast but also a range of flavors. Avoid any potatoes with green patches, as they can taste bitter and may be toxic.
How should I store leftovers of Creamy Mustard Roasted Potatoes?
To keep your leftovers fresh, store them in an airtight container in the refrigerator for up to 3 days. When ready to eat, gently reheat them in the oven to help maintain their texture. Preheat your oven to 350°F (175°C) and heat for about 15-20 minutes until warmed through and a bit crispy.
Can I freeze Creamy Mustard Roasted Potatoes?
Certainly! To freeze, first allow the potatoes to cool completely. Then, place them in a freezer-safe container, ensuring they are tightly sealed to prevent freezer burn.

What should I do if my mustard sauce is too runny?
If you find that your mustard sauce is a bit too runny for your liking, don’t worry! You can easily thicken it by making a cornstarch slurry.

Continue cooking while stirring for 2-3 minutes until the sauce reaches your desired thickness.
Are Creamy Mustard Roasted Potatoes suitable for everyone, including those with allergies?
It’s important to check ingredient labels, as this dish does contain dairy and may not be suitable for lactose-intolerant individuals. You can make a dairy-free version by substituting heavy cream with coconut milk or a dairy-free cream alternative, and using vegetable broth. If anyone is allergic to mustard, consider using a herbed sauce or a simple garlic and olive oil dressing instead.
