Step‑by‑Step Instructions for Crispy Roasted Mustard Potatoes
Step 1: Preheat the Oven
Begin by preheating your oven to 425°F (220°C). For optimal crispiness, place a large, heavy baking sheet or roasting pan inside while it preheats. This ensures the baking surface is piping hot when the potatoes are added, promoting that beautiful golden crust for your Crispy Roasted Mustard Potatoes.
Step 2: Prepare the Potatoes
Thoroughly wash and scrub 1.5 lbs of baby potatoes or small Yukon Gold to remove any dirt. After washing, pat them very dry with a clean kitchen towel or paper towels, as any moisture can prevent them from crisping beautifully during roasting. Dry potatoes are key for achieving that desired crunch!
Step 3: Cut the Potatoes
Once dry, halve the baby potatoes lengthwise; if you have larger ones, cut them into even bite-sized wedges or quarters. This step ensures that your potatoes cook evenly, allowing all sides to perfect that crisp texture you’re after in your Crispy Roasted Mustard Potatoes.
Step 4: Whisk the Mustard Mixture
In a large mixing bowl, combine 3 tablespoon Dijon mustard, 1 tablespoon whole-grain mustard, and 3 tablespoon olive oil. Add in 2 finely minced garlic cloves, 1.5 teaspoon kosher salt, 1 teaspoon black pepper, 1 teaspoon smoked paprika, and the herbs: 1 teaspoon dried thyme and 1 teaspoon dried rosemary. If using, mix in 1 teaspoon onion powder, and optionally, 1 teaspoon honey or maple syrup, and 1 tablespoon lemon juice or vinegar. Whisk until the mixture is smooth and well-emulsified.
Step 5: Coat the Potatoes
Add the cut potatoes to the bowl with the mustard mixture and toss them well until every piece is beautifully coated. This step infuses your Crispy Roasted Mustard Potatoes with robust flavor. For enhanced taste, let them marinate in the mustard mix for 5–10 minutes before roasting.
Step 6: Prepare the Baking Sheet
Carefully remove the hot baking sheet from the oven. Drizzle or brush the surface with a little extra olive oil to create a non-stick surface and to promote browning. This small step can make a significant difference in texture, ensuring your potatoes crisp up wonderfully!
Step 7: Arrange the Potatoes
Transfer the coated potatoes onto the hot baking sheet, spreading them out into a single even layer. Aim to place them cut-side down to maximize browning, ensuring they have enough space between them to allow air circulation, which prevents steaming.
Step 8: Roast to Perfection
Roast the potatoes in your preheated oven for 20 minutes without stirring. This allows the bottoms to brown and crisp nicely. After 20 minutes, flip the potatoes gently using a spatula, scraping off any delicious browned bits stuck to the pan. Roast for an additional 15–20 minutes until they are deep golden brown and tender when pierced with a fork.
Step 9: Final Touches
Once your Crispy Roasted Mustard Potatoes are perfectly roasted, remove them from the oven. Immediately sprinkle with flaky sea salt if you wish for an extra flavor kick. Toss them gently to distribute any pan drippings and seasonings, then garnish with 2 tablespoon finely chopped fresh parsley, adding a burst of color and freshness.
Step 10: Serve and Enjoy
Serve the crispy roasted mustard potatoes hot, adding lemon wedges on the side for an optional zesty flavor enhancement. Whether as a stunning side for dinner or a flavorful addition to a gathering, these potatoes are sure to delight!

Expert Tips for Crispy Roasted Mustard Potatoes
• Choose the Right Potatoes: Baby potatoes or small Yukon Golds work best for achieving that crispy texture. They hold their shape and provide even cooking.

• Use Hot Baking Sheet: Preheating the baking sheet is crucial. This initial burst of heat helps to create a golden, crunchy crust that makes these potatoes irresistible.
• Flip for Even Roasting: Don’t forget to flip the potatoes halfway through the roasting time. This ensures that all sides get that delightful brown color and crispiness.
• Season Generously: Feel free to adjust the spices and herbs to your taste. A little extra salt or a splash of lemon juice can elevate the flavors of your Crispy Roasted Mustard Potatoes even more!

Crispy Roasted Mustard Potatoes Recipe FAQs

Absolutely! For the best results, I recommend using baby potatoes or small Yukon Golds, as they are particularly suited for achieving that delightful crispiness. They hold their shape well and cook evenly, providing a scrumptious texture.
How should I store leftover Crispy Roasted Mustard Potatoes?

If your potatoes aren't crisping up, it usually means there’s too much moisture. Be sure to dry your washed potatoes thoroughly with paper towels before they enter the oven.
