Creamy Mustard Roasted Potatoes Ingredients
For the Potatoes
• Baby Potatoes – Use a mix of yellow and red for a lovely color contrast and texture, or substitute with larger varieties, chopped.
• Extra Virgin Olive Oil – Drizzling this will enhance browning and moisture; adjust the amount to your preference.
• Kosher Salt – Season to taste; it’s key to bring out the natural flavors of the potatoes.
• Pepper – Freshly cracked provides warmth and depth; adjust based on your spice tolerance.
For the Creamy Sauce
• Butter – Adds a luxurious richness; swap with olive oil for a dairy-free alternative.
• Shallot – Brings a subtle sweetness; finely diced onion makes a perfect substitute if you’re out.
• Garlic Cloves – Fresh garlic is essential for its pungency; avoid garlic powder for the best flavor.
• Chicken or Vegetable Broth – Use vegetable broth for a vegetarian option; it serves as the base for the sauce.
• Dijon Mustard – This is where the tanginess comes from; whole grain mustard can be a delightful alternative for texture.
• Grainy Mustard – Adds an extra layer of tang; pick your favorite for a personal twist.
• Heavy Cream – Enriches the sauce; coconut cream is a delicious dairy-free option.
• Cornstarch – Essential for thickening the sauce; flour can be used if you prefer, just adjust cooking time.
• Water – Used to create a slurry with cornstarch; it ensures even thickening.
• Lemon Juice – Brightens the sauce beautifully; fresh juice is best for optimal flavor.
• Fresh Dill – Offers a fresh, aromatic finish; parsley can substitute if dill is unavailable.

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 is ideal for achieving that golden-brown crust on your baby potatoes. While the oven warms, gather your baking sheet and line it with parchment paper for easy cleanup and to prevent sticking.
Step 2: Prepare the Potatoes
In a large mixing bowl, combine your washed and halved baby potatoes with a drizzle of extra virgin olive oil, kosher salt, and freshly cracked pepper. Toss them well to ensure an even coating. Spread the seasoned potatoes in a single layer on your prepared baking sheet, making sure they have space to roast evenly.
Step 3: Roast the Potatoes
Place the baking sheet in the preheated oven and roast the baby potatoes for 35–40 minutes. Halfway through, give them a shake or flip them with a spatula for even browning. They are ready when they are crispy on the outside and tender when pierced with a fork.
Step 4: Sauté the Aromatics
While the potatoes are roasting, heat a skillet over medium heat and melt a tablespoon of butter along with a splash of olive oil. Add finely diced shallots and sauté for about 3-4 minutes, until they are translucent and softened. Then, stir in minced garlic and sauté for an additional minute until fragrant.
Step 5: Create the Sauce Base
Pour in your chicken or vegetable broth into the skillet, bringing it to a gentle simmer. Whisk in the Dijon and grainy mustard, along with a pinch of salt and pepper. Let the mixture simmer for about 5-7 minutes, allowing it to reduce by a third, which intensifies the flavors surprisingly well.
Step 6: Make It Creamy
Once reduced, stir in the heavy cream, bringing the sauce back to a simmer. In a small bowl, mix cornstarch with a bit of water to create a slurry, and then whisk it into the cream sauce. Continue to cook for 2-3 minutes until the sauce thickens; it should coat the back of a spoon beautifully.
Step 7: Add the Finishing Touches
Remove the creamy mustard sauce from heat and stir in fresh lemon juice and chopped dill for a pop of brightness and flavor. Taste and adjust seasoning as necessary; you want a balanced flavor that highlights the creamy mustard.
Step 8: Assemble and Serve
Layer the roasted baby potatoes in a serving bowl, generously drizzling the creamy mustard sauce over the top. For a visually appealing presentation, repeat the layers if you like. Serve warm and enjoy the delightful flavors of your Creamy Mustard Roasted Potatoes, perfect for any gathering or cozy dinner at home.

Make Ahead Options
These Creamy Mustard Roasted Potatoes are a fantastic choice for meal prep, allowing you to save time on busy weeknights! You can prepare the roasted potatoes up to 24 hours in advance by cooking and then storing them in an airtight container in the refrigerator. When ready to serve, simply reheat them in the oven until warmed through—this helps maintain their crispiness. For the creamy mustard sauce, cook it ahead of time, and hold it in the fridge for up to 3 days. Reheat gently on the stove before drizzling it over your potatoes, ensuring they remain just as delicious. This prep-ahead approach makes enjoying this comfort food even easier during the week!
Expert Tips for Creamy Mustard Roasted Potatoes
Even Coating: Ensure potatoes are evenly coated with olive oil for optimal roasting; this prevents uneven texture and enhances browning.
Watch the Sauce: Keep an eye on the sauce after adding the slurry, as it thickens rapidly; stir often to achieve the desired creaminess without clumps.
Optimal Roasting: Spread the potatoes in a single layer on the baking sheet; overcrowding can lead to steaming rather than roasting, affecting their tenderness.
Choosing Mustard: Experiment with different mustard varieties to find your perfect tangy flavor; each type brings its own unique character to the creamy sauce.
Fresh Ingredients: Always use fresh garlic and herbs to elevate the flavor of your dish; dried substitutes won’t provide the same aromatic punch.
Storage Tips for Creamy Mustard Roasted Potatoes
Fridge: Store leftover Creamy Mustard Roasted Potatoes in an airtight container for up to 3 days. This keeps them fresh and prevents odors from mingling.
Freezer: For longer storage, freeze the potatoes in a single layer on a baking sheet until solid, then transfer to a zip-top bag. They can last up to 3 months.
Reheating: Reheat in the oven at 350°F (175°C) for about 15-20 minutes until heated through; this will help restore their crispy texture. Avoid microwaving, as it can make them soggy.
Airtight Seal: Ensure containers are airtight to preserve flavor and prevent freezer burn, which can affect the creamy mustard sauce’s taste.

Creamy Mustard Roasted Potatoes Recipe FAQs
How do I choose the best baby potatoes?
Absolutely! When selecting baby potatoes, look for those that are firm, smooth, and evenly sized. Avoid any with dark spots or wrinkles. A mix of yellow and red-skinned varieties not only enhances the dish’s color but also adds different textures and flavors to your Creamy Mustard Roasted Potatoes.
How do I store leftover Creamy Mustard Roasted Potatoes?
To keep your delicious leftovers fresh, store them in an airtight container in the refrigerator for up to 3 days. This prevents them from absorbing other odors in your fridge. Reheating them in the oven at 350°F (175°C) for about 15-20 minutes will help maintain their crispy texture.
Can I freeze Creamy Mustard Roasted Potatoes?
Very much so! To freeze, spread the roasted potatoes in a single layer on a baking sheet and freeze until solid. Then, transfer them to a zip-top bag and label with the date. They can be stored for up to 3 months. When ready to enjoy, bake them straight from the freezer at 400°F (200°C) for 25-30 minutes until heated through.
What should I do if the cream sauce becomes too thick?
If your creamy mustard sauce thickens more than desired, don’t worry! Simply whisk in a little more broth or cream to reach your desired consistency. If you’re using cornstarch as a thickener, make sure to mix it with water first to avoid lumps and incorporate it gradually into the sauce while stirring.
Are these potatoes safe for my pet dog?
While baby potatoes can be safe in small amounts, it’s important to feed them plain without the cream sauce or seasonings, as many ingredients in the sauce can be harmful to dogs (like garlic and onions). Always consult your vet before introducing any new food to your pet’s diet.
Can I make this recipe gluten-free?
Absolutely! To make your Creamy Mustard Roasted Potatoes gluten-free, simply substitute regular cornstarch with a gluten-free variant or use a certified gluten-free thickener. Always double-check your mustard and broth labels to ensure they are gluten-free as well!
