Ingredients:
- 1.5 lbs (about 700 g) baby potatoes or small Yukon Gold potatoes, halved (or quartered if large)
- 3 tbsp Dijon mustard
- 1 tbsp whole-grain mustard (or additional Dijon if unavailable)
- 3 tbsp olive oil (plus a little extra for the pan)
- 2 cloves garlic, finely minced or grated
- 1.5 tsp kosher salt (or 1 fine sea salt)
- 1 tsp freshly ground black pepper
- 1 tsp smoked paprika (or sweet paprika)
- 1 tsp dried thyme (or 2 fresh thyme leaves, chopped)
- 1 tsp dried rosemary, crushed (or 2 fresh rosemary, finely chopped)
- 1 tsp onion powder (optional but recommended)
- 1 tsp honey or maple syrup (optional, for balanced flavor)
- 1 tbsp lemon juice or apple cider vinegar
- 2 tbsp finely chopped fresh parsley (for garnish)
- Flaky sea salt, to finish (optional)
- Lemon wedges, for serving (optional)
Method:
Step 1: Preheat the Oven
Preheat your oven to 425°F (220°C) and place a large, heavy baking sheet or roasting pan inside while it preheats so it gets very hot. This helps the potatoes crisp on contact.
Step 2: Prepare the Potatoes
Wash and scrub the potatoes thoroughly; leaving the skins on not only adds color but also texture and flavor. Pat them very dry with a clean kitchen towel or paper towels—moisture is the enemy of crispiness! Cut the baby potatoes in half; if you’re using larger potatoes, cut them into even bite-sized wedges or quarters for even roasting.
Step 3: Make the Mustard Marinade
In a large mixing bowl, combine Dijon mustard, whole-grain mustard, olive oil, minced garlic, salt, black pepper, smoked paprika, thyme, rosemary, onion powder (if using), honey or maple syrup (if using), and lemon juice or vinegar. Whisk until the mixture is smooth, thick, and emulsified, creating a flavorful coat for your potatoes.
Step 4: Coat the Potatoes
Add the dried, cut potatoes to the bowl with the mustard mixture and toss very well. Use a spatula or your hands to ensure every surface of each potato piece is lovingly coated with the mustard mixture. Let them sit while the oven finishes preheating for 5–10 minutes to allow the flavors to infuse.
Step 5: Prepare the Hot Pan
Carefully remove the preheated baking sheet from the oven (make sure to use oven mitts, as it will be very hot!) and lightly drizzle or brush the surface with a thin layer of olive oil to prevent sticking and encourage browning.
Step 6: Arrange the Potatoes
Transfer the coated potatoes to the hot baking sheet, making sure to spread them out in a single, even layer. Place them cut-side down as much as possible, which helps to achieve a deeply caramelized, crisp surface. Remember to leave a bit of space between potatoes—crowding will lead to steaming instead of roasting.
Step 7: Roast the Potatoes
Place the baking sheet back into the oven on a middle rack and roast for 20 minutes without stirring, allowing the bottoms to brown and crisp. After 20 minutes, use a thin spatula to flip the potatoes, scraping up any browned bits from the pan. Continue roasting for another 15–20 minutes, or until the potatoes are deep golden brown and crisp on the edges, and tender in the center when pierced with a fork (total roasting time about 35–40 minutes).
Step 8: Finish and Season
Once roasted, remove the potatoes from the oven. Immediately sprinkle with a pinch of flaky sea salt for that extra crunch and flavor. Toss gently on the tray or in a serving bowl to distribute any delectable pan drippings. Sprinkle chopped fresh parsley over the top for a burst of color!
Step 9: Serve
Serve the crispy roasted mustard potatoes hot, with extra lemon wedges on the side for squeezing if you prefer a brighter flavor. They pair wonderfully with roasted chicken, grilled meats, sausages, fish, or as a bold-flavored vegetarian side with salads and roasted vegetables.
Serving Suggestions & Pairings
These crispy roasted mustard potatoes are incredibly versatile. Consider pairing them with:
- Grilled or roasted chicken

Storage & Leftovers Guide
Leftover roasted potatoes can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in a hot oven to restore their crispy texture. You can also toss them into a breakfast hash the following morning!
Kitchen Wisdom & Success Tips
- Ensure Potatoes Are Dry: This helps them crisp up better in the oven.
- Don’t Crowd the Pan: Overcrowding traps steam, leaving you with soggy potatoes instead of crispy bites.
- Experiment with Mustard: Feel free to mix up the mustards you use—adding whole-grain gives a lovely texture.
- Try Different Herbs: Fresh herbs can lend new flavors; try rosemary, oregano, or even dill for a fresh twist.
Flavor Variations & Adaptations
Feel free to get creative! You could add:
- Cheese: Sprinkle some grated Parmesan or feta on top in the last few minutes of roasting for an indulgent touch.
- Spicy Kick: Add crushed red pepper flakes or sriracha to the mustard mixture for a fiery flavor blast.
- Berry Fusion: Toss in some dried cranberries or walnuts for an extra layer of flavor and texture.
