Creamy Mustard Roasted Potatoes Ingredients
• Here’s what you’ll need to make this delicious comfort food!
For the Potatoes
• Baby Potatoes – Tender base that soaks up the creamy sauce; feel free to swap for larger potatoes cut into smaller pieces.
• Extra Virgin Olive Oil – Adds moisture and flavor while roasting; adjust to your taste preference.
• Kosher Salt – Enhances the flavors; you can tweak the amount according to your liking.
• Pepper – Adds just the right touch of heat; use freshly ground for the best taste.
For the Cream Sauce
• Butter – Richness for the sauce; substitute with additional olive oil for a dairy-free version.
• Shallot – Provides a gentle onion flavor; yellow onion works as an excellent replacement.
• Garlic Cloves – Brings a savory depth; mince for even distribution throughout the sauce.
• Chicken or Vegetable Broth – The sauce’s foundation; opt for vegetable broth to keep it vegetarian-friendly.
• Dijon Mustard – Adds tang; you can swap it for yellow mustard, but the flavor will differ.
• Grainy Mustard – Gives texture and extra mustard punch; omit if you don’t have it.
• Heavy Cream – Provides luxurious creaminess; feel free to use half-and-half or non-dairy cream for lighter alternatives.
• Cornstarch – Thickens the sauce; arrowroot can be used as a corn-free substitute.
• Water – Needed to create the cornstarch slurry.
• Lemon Juice – Brightens the sauce’s flavor; a little goes a long way for perfect balance.
• Chopped Fresh Dill – Adds a burst of freshness; switch to parsley for a different herbal note.
Step‑by‑Step Instructions for Creamy Mustard Roasted Potatoes
Step 1: Preheat and Prepare
Preheat your oven to 400°F (200°C). While the oven warms, wash and dry the baby potatoes thoroughly. Line a baking sheet with parchment paper for easy cleanup, then place the potatoes on it, ensuring they’re in a single layer for even roasting. This is the first step in creating your delightful creamy mustard roasted potatoes!
Step 2: Season and Roast the Potatoes
Drizzle the potatoes generously with extra virgin olive oil, making sure each one is well-coated. Sprinkle with kosher salt and freshly cracked pepper for added flavor. Roast them in the preheated oven for 35-40 minutes, or until they are golden brown and fork-tender, stirring halfway through to achieve an even roast.
Step 3: Sauté Aromatics
In a skillet over medium heat, melt 2 tablespoons of butter with an equal amount of olive oil. Add the finely chopped shallots and sauté for about 3-4 minutes, stirring occasionally, until they’re softened and fragrant. This aromatic base will enhance the richness of your creamy mustard sauce.
Step 4: Create the Sauce Base
To the softened shallots, add the minced garlic and cook for an additional minute until fragrant. Pour in your choice of chicken or vegetable broth, bringing the mixture to a simmer. Allow it to cook for a few minutes until slightly reduced, which will deepen the flavors for your creamy mustard roasted potatoes.
Step 5: Whisk in the Mustards
Once simmering, whisk in both the Dijon and grainy mustard into the broth, stirring well to combine. Season the mixture with a pinch of salt and pepper, then let it reduce further for about 5 minutes. This will create a robust sauce perfect for coating your roasted potatoes.
Step 6: Add Cream and Thicken
Stir in the heavy cream into the sauce, blending until smooth. In a small bowl, mix cornstarch with a bit of water to form a slurry, then slowly incorporate it into the simmering sauce. Continue to cook for 2-3 minutes, or until the sauce thickens and becomes velvety—this is the heart of your creamy mustard roasted potatoes!
Step 7: Finish with Lemon and Dill
Remove the skillet from the heat and stir in a splash of fresh lemon juice for brightness. Taste the sauce, adjusting seasoning if necessary, then toss in the chopped fresh dill right before serving. This will not only add a pop of color but also elevate the flavor profile of your creamy mustard roasted potatoes.

Expert Tips for Creamy Mustard Roasted Potatoes
• Evenly Spread Potatoes: Ensure the potatoes are spread out in a single layer on the baking sheet to promote even roasting and prevent steaming.
• Check for Doneness: Use a fork to test the potatoes after 35 minutes; they should be tender and lightly browned. Adjust roasting time if needed.
• Adjust Sauce Consistency: The creamy sauce may thicken as it sits; stir in a splash of broth or cream to reach your desired consistency before serving.
• Fresh Herbs Matter: For the best flavor, add fresh dill just before serving; it brightens the dish and enhances the overall taste of the creamy mustard roasted potatoes.
• Mind the Heat: Use fresh ground pepper for a subtle kick; pre-ground pepper may lose its freshness, diminishing flavor.
• Taste as You Go: Always taste the sauce while cooking to adjust seasonings—everyone’s palate is different, and this will ensure your creamy mustard roasted potatoes have the perfect flavor balance.

Creamy Mustard Roasted Potatoes Recipe FAQs
What type of potatoes are best for this recipe?
Absolutely! Baby potatoes are ideal for their tenderness and ability to soak up the creamy sauce. I recommend a mix of yellow flesh and red-skinned potatoes. If baby potatoes aren’t available, larger potatoes can be easily substituted by cutting them into smaller, uniform pieces to ensure they cook evenly.
How should I store leftover creamy mustard roasted potatoes?
After enjoying your delightful creamy mustard roasted potatoes, store any leftovers in an airtight container in the refrigerator, where they will stay fresh for up to 3 days. Just be sure to let them cool completely before sealing to avoid excess moisture. This way, you’ll preserve that luscious creaminess for your next meal!
Can I freeze creamy mustard roasted potatoes?
Very! For longer storage, you can freeze these creamy mustard roasted potatoes. Allow them to cool completely first, then place them in a freezer-safe container or resealable bag, removing as much air as possible. They can last up to 2 months in the freezer. When you’re ready to enjoy, simply thaw in the refrigerator overnight and reheat gently in the oven to maintain their delightful texture.
What if my sauce is too thick?
If your sauce thickens more than you like after cooking, it’s no problem! Simply stir in a splash of broth or cream to reach your desired consistency. This adjustment will help bring back that velvety texture that’s so signature to creamy mustard roasted potatoes. Remember, flavors meld beautifully when you taste as you go, so don’t hesitate to tweak it!
Are there any dietary considerations for this dish?
Absolutely! This recipe is vegetarian-friendly as written. For those with dietary restrictions, you can use vegetable broth instead of chicken broth. Additionally, if you’re catering to dairy-free diets, swapping the butter with extra olive oil and using non-dairy cream can keep this dish just as enjoyable for everyone!
Can I add different herbs or spices to the recipe?
The more the merrier! While fresh dill adds a nice touch of freshness, feel free to experiment with other herbs like parsley, thyme, or chives, depending on your taste preferences.
