Step‑by‑Step Instructions for Creamy Mustard Roasted Potatoes
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (204°C). This temperature is perfect for transforming baby potatoes into crispy-tender delights. Preheating ensures that they roast evenly, allowing that golden-brown exterior to develop beautifully.
Step 2: Prepare the Potatoes
Wash and dry the baby potatoes, then place them on a baking sheet lined with parchment paper. Drizzle generously with extra virgin olive oil, followed by a sprinkle of kosher salt and freshly cracked pepper. Toss everything well with your hands until the potatoes are thoroughly coated, ensuring every piece gets that lovely flavor.
Step 3: Roast the Potatoes
Slide the baking sheet into your preheated oven and roast the potatoes for 35–40 minutes. About halfway through, give them a shake or stir to promote even browning. They are ready when they are fork-tender and boast a crispy, golden crust, inviting you to relish every bite of these mustard roasted potatoes.
Step 4: Sauté the Aromatics
While the potatoes roast, prepare the creamy mustard sauce. In a skillet over medium heat, combine butter and a splash of olive oil. Once melted, add finely diced shallot and sauté for 3–4 minutes until softened and fragrant. Toss in minced garlic and allow it to cook for an additional minute, stirring constantly to avoid burning.
Step 5: Create the Sauce Base
Pour in your choice of chicken or vegetable broth to the skillet, stirring well. Increase the heat slightly and bring the mixture to a gentle simmer. Whisk in the Dijon and grainy mustard, along with a pinch of salt and pepper, allowing the sauce to reduce by about one-third for more concentrated flavors.
Step 6: Incorporate the Cream
Once the broth has reduced, pour in the heavy cream, stirring to combine. In a small bowl, mix cornstarch with an equal amount of water to create a slurry. Add this to the skillet, stirring continuously until the sauce thickens, which should take about a minute. The creamy sauce will beautifully coat your mustard roasted potatoes.
Step 7: Finish with Lemon and Dill
Remove the skillet from heat, then stir in fresh lemon juice to brighten the flavors. Taste and adjust seasoning if needed. For a pop of freshness, fold in freshly chopped dill or substitute with parsley if desired. This adds a delightful herbal note to your comforting sauce.
Step 8: Serve the Dish
To serve, layer the crispy roasted potatoes in a serving bowl. Drizzle the velvety mustard sauce generously over the top, ensuring every bite is coated. Garnish with additional fresh dill for a touch of color and flavor, and enjoy the warm, comforting delight of your creamy mustard roasted potatoes.

Expert Tips for Mustard Roasted Potatoes
-
Even Spacing: Ensure the baby potatoes are spread out on the baking sheet to avoid overcrowding. This promotes even roasting and crispy edges.
-
Uniform Size: If using larger potatoes, chop them into similarly sized pieces. This helps achieve consistent cooking throughout the mustard roasted potatoes.
-
Fresh Herbs: Fresh dill is best for flavor, yet if you can’t find it, parsley can substitute nicely. Always taste before serving to adjust the herbiness.
-
Cream Care: Simmer the sauce gently to prevent the cream from curdling. It’s crucial for achieving a silky texture in your mustard roasted potatoes.
-
Flavor Boost: For an extra zing, consider adding a dash of cayenne or swapping mustards for a spicy kick. Adjust to personal taste and enjoy the depth!

Creamy Mustard Roasted Potatoes Recipe FAQs
What type of baby potatoes should I use for this recipe?
Absolutely! I recommend using a mix of yellow flesh and red-skinned baby potatoes. This combination not only adds visual appeal but also enhances the flavor profile, giving you the best of both worlds in every bite.
How should I store leftover mustard roasted potatoes?
After preparing your creamy mustard roasted potatoes, store any leftovers in an airtight container in the refrigerator. They will stay fresh for up to 3 days. A tip I often share is to reheat them in the oven to regain that lovely crispy texture—around 350°F (175°C) works best!
Can I freeze these mustard roasted potatoes?
Yes, you can! For freezing, allow the potatoes to cool completely, then transfer them into a freezer-safe container or bag. They can be frozen for up to 3 months. When ready to enjoy, simply thaw them overnight in the fridge before reheating in the oven.
What should I do if the cream sauce curdles during cooking?
Very! If your cream sauce curdles, it usually means the heat was too high or the cream was added too quickly. To fix it, reduce the heat and whisk vigorously until smooth. If it remains lumpy, you might want to blend the sauce with an immersion blender, which can help salvage the creamy texture.
Are there alternative ingredients for making this recipe gluten-free?
Definitely! To make your creamy mustard roasted potatoes gluten-free, ensure that you use gluten-free chicken or vegetable broth and replace cornstarch with a gluten-free thickening agent, like arrowroot powder. This way, you can cater to dietary needs without sacrificing flavor.
What can I do if I can’t find fresh dill?
If fresh dill isn’t available, don’t worry! Parsley is a great substitute. You can also use dried dill, using about a third of the amount, as it’s more concentrated. This will still provide that herbal freshness to your creamy mustard roasted potatoes, making them delicious in your absence!
