• 1.5 teaspoon kosher salt – helps elevate the overall taste and brings out the richness of the potatoes.
• 1 teaspoon freshly ground black pepper – adds a gentle kick that balances the creaminess of the mustard.
• 3 tablespoon olive oil – ensures crispy, golden edges while roasting.
For the Mustard Marinade
• 3 tablespoon Dijon mustard – provides a tangy, sharp flavor that's essential in our crispy roasted mustard potatoes.
• 1 tablespoon whole-grain mustard – adds texture and a slightly nuttier taste; substitute with more Dijon if needed.
• 1 teaspoon smoked paprika – delivers a warm depth of flavor; sweet paprika can be used for a milder taste.
• 1 teaspoon dried thyme – contributes a lovely herbal note; fresh thyme can add extra brightness if you have it.
• 1 teaspoon dried rosemary – infuses a piney aroma that complements the potatoes beautifully.
• 1 teaspoon onion powder (optional) – enhances the savory flavors and adds depth to the marinade.
• 1 teaspoon honey or maple syrup (optional) – balances out the tanginess of the mustard for a well-rounded flavor.

Step‑by‑Step Instructions for Crispy Roasted Mustard Potatoes
Step 1: Preheat the Oven
Begin by preheating your oven to 425°F (220°C). Place a large, heavy baking sheet or roasting pan inside as it heats, ensuring the surface gets very hot. This step is crucial for achieving that crispy texture in your Crispy Roasted Mustard Potatoes.
Step 2: Prepare the Potatoes
Wash and scrub 1.5 lbs of baby potatoes thoroughly, leaving the skins on for extra texture and flavor. Then, pat them very dry with a clean kitchen towel or paper towels; this will help prevent steaming during roasting.
Step 3: Cut the Potatoes
Slice the baby potatoes in half; for larger ones, cut them into even bite-sized wedges or quarters. Aim for uniform pieces to ensure even cooking, which is essential for perfectly roasted Crispy Roasted Mustard Potatoes.
Step 4: Make the Mustard Marinade
In a large mixing bowl, whisk together 3 tablespoon of Dijon mustard, 1 tablespoon of whole-grain mustard, 3 tablespoon of olive oil, 2 cloves of minced garlic, and seasonings including salt, pepper, smoked paprika, thyme, rosemary, onion powder (if using), honey (if desired), and lemon juice. Blend until smooth and emulsified for maximum flavor.
Step 5: Coat the Potatoes
Add the dried, cut potatoes to the bowl with your flavorful mustard mixture. Toss vigorously until every potato is thoroughly coated in the marinade, ensuring an even distribution of flavors across all your Crispy Roasted Mustard Potatoes.
Step 6: Marinate the Potatoes
Let the coated potatoes sit in the bowl for 5–10 minutes, allowing them to absorb the delicious marinade. This short resting period enhances their flavor and prepares them for roasting, while your oven finishes preheating.
Step 7: Prepare the Baking Sheet
Carefully remove the preheated baking sheet from the oven. Lightly drizzle or brush its surface with olive oil to prevent sticking and promote that lovely crispiness to your potatoes as they roast.
Step 8: Arrange the Potatoes
Transfer the marinated potatoes to the hot baking sheet, spreading them out into a single, even layer with the cut sides facing down where possible. This promotes even browning and crispness throughout your Crispy Roasted Mustard Potatoes.
Step 9: First Roast
Roast the potatoes for 20 minutes without stirring. This allows the cut sides to become beautifully browned and crispy, creating that satisfying texture everyone loves in roasted dishes.
Step 10: Flip the Potatoes
After 20 minutes, use a thin spatula to carefully flip the potatoes, scraping up any delicious browned bits from the pan. This step is essential to ensure all sides achieve that golden-brown hue and added flavor.
Step 11: Final Roast
Continue roasting for another 15–20 minutes until the potatoes are deep golden brown and crisp on the edges, yet tender inside. Keep an eye on them as they roast to prevent overcooking.
Step 12: Finish the Potatoes
Once roasted, remove the potatoes from the oven. Sprinkle them with flaky sea salt for added flavor if desired, enhancing the taste of your Crispy Roasted Mustard Potatoes.
Step 13: Toss and Garnish
In the baking tray or a serving bowl, gently toss the potatoes to distribute any pan drippings and seasonings. Finish by sprinkling with finely chopped fresh parsley for a vibrant touch.
Step 14: Serve
Serve your Crispy Roasted Mustard Potatoes hot, accompanied by extra lemon wedges on the side for those who enjoy a burst of citrus. This dish is bound to be a hit at your dining table!

Tips for the Best Crispy Roasted Mustard Potatoes
Dry is Key: Ensure the potatoes are patted very dry after washing; this prevents steaming and promotes a crispy texture in your roasted mustard potatoes.
Don't Overcrowd: Place the potatoes in a single, even layer on the baking sheet to allow for proper airflow and crispness; overcrowding can lead to soggy potatoes.
High Heat Essential: Roast at 425°F (220°C) for that perfect golden-brown finish. Lower temperatures can result in softer, less crispy potatoes.
Flipping Matters: Flip the potatoes halfway through roasting to ensure even browning on all sides; this step is crucial for achieving the ideal crispy exterior.
Taste and Adjust: Don't be afraid to tweak the seasoning; taste the mustard marinade before coating the potatoes, and adjust salt, pepper, or spices to suit your palate.

Crispy Roasted Mustard Potatoes Recipe FAQs
How do I select the best potatoes for this recipe?
Absolutely! When choosing potatoes, look for firm baby potatoes or small Yukon Golds that are free from dark spots or blemishes. Fresh potatoes will have smooth skins and feel heavy for their size. Avoid any that have sprouted or are soft, as they won’t yield the same delicious results.
How should I store leftover crispy roasted mustard potatoes?
Very easily! After they’ve completely cooled, store your leftover crispy roasted mustard potatoes in an airtight container in the refrigerator for up to 3 days. I recommend placing parchment paper between layers if you have a large batch; this helps maintain their crunchiness when reheating.
Can I freeze crispy roasted mustard potatoes?
Absolutely! To freeze, first arrange the potatoes in a single layer on a baking sheet and freeze them for 1-2 hours until solid. Then, transfer the frozen potatoes to a freezer-safe bag or container. They can be kept in the freezer for up to 3 months. When you're ready to enjoy them, you can reheat directly from frozen.
What should I do if my potatoes are not crispy after roasting?
No worries! If you find your crispy roasted mustard potatoes aren't as crispy as you'd like, it could be due to excess moisture or overcrowding on the baking sheet. Ensure your potatoes are completely dry before roasting, and try spreading them out in a single layer to allow proper airflow during cooking. If they need a little extra crisp, return them to the oven for an additional 5-10 minutes.
Are these potatoes safe for a gluten-free diet?
Very! The ingredients in crispy roasted mustard potatoes are inherently gluten-free, as long as you ensure the mustards you use do not contain any gluten additives. It's always wise to check labels to ensure no cross-contamination has occurred!
Can my dog enjoy these crispy roasted mustard potatoes?
While potatoes are safe for dogs in moderation, I recommend avoiding the mustard and seasonings. The spices and salt can upset their stomachs. If you'd like to share a treat with your furry friend, simply set aside a few plain cooked potato pieces and let them enjoy!
