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). Place a large, heavy baking sheet or roasting pan in the oven as it preheats, allowing it to get very hot. This ensures that the potatoes start crisping right away.

Step 2: Prepare the Potatoes

Wash and scrub the potatoes thoroughly, leaving the skins on for added texture and flavor. Pat them very dry with a clean kitchen towel or paper towels, as moisture can prevent them from crisping. Cut the baby potatoes in half; if using slightly larger potatoes, cut them into even bite-sized wedges or quarters so they roast evenly.

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 smooth, thick, and emulsified.

Step 4: Coat the Potatoes

Add the dried, cut potatoes to the bowl with the mustard mixture. Toss well, using a spatula or your hands to ensure every surface of each potato piece is coated. Let the potatoes sit in the marinade for 5–10 minutes while the oven finishes preheating.

Step 5: Prepare the Hot Pan

Carefully remove the preheated baking sheet from the oven (use oven mitts, it will be very hot). 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, spreading them into a single, even layer. Place them cut-side down as much as possible for maximum crispiness. Ensure there is a bit of space between potatoes to avoid steaming.

Step 7: Roast the Potatoes

Place the baking sheet back into the oven on a middle rack. Roast for 20 minutes without stirring to allow 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 if desired for extra texture and flavor. Toss gently on the tray or in a serving bowl to distribute any pan drippings and seasonings. Sprinkle with chopped fresh parsley over the top.

Step 9: Serve

Serve the crispy roasted mustard potatoes hot, with extra lemon wedges on the side 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 mustard potatoes are incredibly versatile. Serve them alongside your favorite roasted chicken for a classic meal or pair them with grilled sausages for a casual barbecue. For a vegetarian option, they shine as a side to hearty salads or roasted vegetables. Don’t forget to squeeze a bit of that fresh lemon juice over top to brighten their flavors!

Storage & Leftovers Guide

If you find yourself with leftovers (which is not very likely!), store them in an airtight container in the refrigerator. They will keep for about 3 days. To reheat, spread them out on a baking sheet and pop them back into the oven at 375°F (190°C) for about 10-15 minutes, which will help restore their crispiness.

Kitchen Wisdom & Success Tips

• Choose potatoes that are uniform in size to ensure even cooking.
• Make sure to dry the potatoes adequately before applying the marinade.
• Letting the potatoes marinate for a few minutes really helps to enhance the flavor.
• Don’t overcrowd the baking sheet; give the potatoes some space to roast and not steam.
• Always check the doneness with a fork; they should be tender inside and crispy outside.

Flavor Variations & Adaptations

Feel free to experiment with different herbs! Fresh rosemary and thyme add a lovely aroma, but consider adding herbs like oregano or basil for a different twist. You could even substitute the Dijon mustard for spicy mustard or add a kick of cayenne if you enjoy a bit of heat.

Reader Questions & Solutions

1. Why are my potatoes not getting crispy?
   Ensure they are dry before roasting and avoid overcrowding on the baking sheet.

2. Can I use other types of potatoes?
   Absolutely! Just be mindful of the cooking time; larger potatoes may take longer.

3. What if I don’t have Dijon mustard?
   You can use more whole-grain mustard or even a spicy brown mustard for a different taste.

4. How do I know when the potatoes are done?
   They should be golden brown and crispy on the outside, and you should be able to pierce them easily with a fork.

5. Can I make these potatoes in advance?
   While it’s best to eat them fresh, you can prepare them ahead and roast them just before serving.
