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 ensures that your Creamy Mustard Roasted Potatoes will bake evenly and achieve that perfect golden brown exterior. While the oven heats up, gather your baking sheet and prepare the baby potatoes for roasting.
Step 2: Prepare the Potatoes
Spread the cleaned baby potatoes onto the prepared baking sheet. Drizzle with extra virgin olive oil, ensuring each potato is well-coated for maximum crispiness. Season generously with kosher salt and freshly ground pepper, then toss to combine. Roast the potatoes in the preheated oven for 35-40 minutes, turning halfway through until they are tender and golden brown.
Step 3: Sauté the Aromatics
In a medium skillet, heat a combination of butter and olive oil over medium heat. Add the diced shallots, sautéing for about 3-4 minutes until they become soft and fragrant. Introduce minced garlic to the skillet, and continue cooking for another minute, letting the flavorful aromas fill your kitchen.
Step 4: Create the Sauce Base
Pour in the chicken or vegetable broth into the skillet with the sautéed shallots and garlic. Bring this mixture to a gentle simmer, while whisking in both Dijon and grainy mustard along with a pinch of salt and pepper. Allow the broth to reduce by about one-third, concentrating the flavors of your creamy mustard sauce.
Step 5: Add the Cream
Once the broth has reduced, gently stir in the heavy cream, bringing the sauce back to a simmer. In a separate bowl, mix cornstarch with a little water to create a slurry. Slowly whisk this slurry into the simmering cream sauce, allowing it to thicken into a rich, velvety texture that will coat your roasted potatoes beautifully.
Step 6: Finish the Sauce
After the cream sauce has thickened to your desired consistency, remove it from heat. Squeeze in fresh lemon juice to enhance the sauce’s brightness, and taste for seasoning adjustments. This tangy touch elevates the Creamy Mustard Roasted Potatoes, ensuring each bite is bursting with flavor.
Step 7: Assemble and Serve
Layer the perfectly roasted baby potatoes in a serving dish and generously drizzle the mustard cream sauce over the top. For a pop of color and freshness, sprinkle chopped dill across the dish. Serve warm and enjoy the comforting flavors and creamy goodness of your Creamy Mustard Roasted Potatoes.

Storage Tips for Creamy Mustard Roasted Potatoes
Fridge: Store leftovers in an airtight container for up to 3 days to maintain freshness and flavor.
Freezer: While freezing is not ideal for creamy dishes, you may freeze the sauce separately for up to 2 months. Reheat gently on the stove before mixing with freshly roasted potatoes.
Reheating: For the best results, reheat in the oven at 350°F (175°C) to maintain crispiness, or use a microwave for a quick meal.
Serving Suggestions: Pair any reheated portions with fresh herbs to brighten the dish, ensuring your Creamy Mustard Roasted Potatoes taste great, even on day two!

Expert Tips for Creamy Mustard Roasted Potatoes

Creamy Mustard Roasted Potatoes Recipe FAQs
How do I choose the best baby potatoes for this recipe?
Absolutely! Look for baby potatoes that are smooth, firm, and free of any dark spots or blemishes. They should feel heavy for their size. The smaller, the better, for an ideal texture—if you can’t find baby potatoes, you can use larger potatoes but chop them into uniform bite-sized pieces for even cooking.
What is the best way to store leftovers?
Very! Store any leftovers in an airtight container in the refrigerator for up to 3 days. Allowing them to cool completely before sealing will help prevent moisture buildup. When reheating, I recommend using the oven at 350°F (175°C) to maintain their delicious crispiness, or use a microwave if you’re in a hurry!
Can I freeze Creamy Mustard Roasted Potatoes?
While I generally recommend enjoying this dish fresh, you can freeze the sauce separately for up to 2 months. Here’s how: Let the sauce cool completely, then pour it into a freezer-safe container. To reheat, gently warm it on the stove before mixing it with freshly roasted potatoes (not previously frozen) for the best results.
What if my sauce doesn’t thicken?
Don’t worry! If your sauce isn’t thickening as expected, it’s usually just a matter of simmering longer. After adding your cornstarch slurry, allow it to bubble for a few additional minutes, making sure to whisk occasionally. If it still appears too thin, you can mix up another small batch of slurry and add it in gradually until you reach your desired consistency.
Are these potatoes pet-friendly?
Great question! While the individual ingredients in Creamy Mustard Roasted Potatoes are not toxic to pets, it’s best to avoid feeding humans food to your furry friends, particularly due to the butter and seasoning content. If you want to share, do so without the sauce, and opt for plain roasted potatoes instead; they will surely love it!
Can I make this dish dairy-free?
Absolutely! To create a dairy-free version of Creamy Mustard Roasted Potatoes, simply swap the heavy cream for coconut cream or a rich plant-based milk like almond or oat, adjusting the thickness as needed with a little cornstarch slurry. Also, use olive oil instead of butter for the sauté. Enjoy delicious creaminess without the dairy!
