Step‑by‑Step Instructions for Crispy Roasted Mustard Potatoes

Step 1: Preheat the Oven
Begin by preheating your oven to 425°F (220°C). While it heats, place a large, heavy baking sheet or roasting pan in the oven; this will ensure the potatoes get that lovely crispy texture once they're added. This step is crucial for achieving perfectly roasted potatoes, so don't skip it!

Step 2: Prepare the Potatoes
Wash and scrub 1.5 lbs of baby potatoes or small Yukon Gold potatoes thoroughly, keeping the skins on for added texture and flavor. After rinsing, pat the potatoes very dry using a clean towel, as moisture can prevent them from crisping up nicely during roasting.

Step 3: Cut the Potatoes
Slice the potatoes in half. If you're using larger ones, quarter them into even bite-sized wedges. This ensures uniform cooking and enables all pieces to crisp up beautifully in the oven. Your goal is even sizes to achieve consistent doneness across the board.

Step 4: Make the Mustard Mixture
In a large mixing bowl, whisk together 3 tablespoons of Dijon mustard, 1 tablespoon of whole-grain mustard, 3 tablespoons of olive oil, 2 cloves of finely minced garlic, 1.5 teaspoons of kosher salt, 1 teaspoon of freshly ground black pepper, 1 teaspoon of smoked paprika, and 1 teaspoon each of dried thyme and dried rosemary. This tangy and aromatic mixture will coat your potatoes perfectly.

Step 5: Coat the Potatoes
Add the prepared potatoes to the mustard mixture, tossing well to coat every piece thoroughly. Make sure each potato is deliciously covered. Let them sit for about 5 to 10 minutes; this resting period helps the flavors penetrate and enhances the final taste of your crispy roasted mustard potatoes.

Step 6: Prepare the Baking Sheet
Carefully remove the preheated baking sheet from the oven using oven mitts, as it will be very hot. Lightly drizzle or brush some olive oil onto the sheet to prevent the potatoes from sticking; this step will contribute to that coveted crispness as they roast.

Step 7: Spread the Potatoes
Transfer the coated potatoes to the hot baking sheet, spreading them out into a single, even layer with the cut-side down. This arrangement allows for maximum exposure to the heat, setting the stage for those golden-brown, crispy edges that make these crispy roasted mustard potatoes irresistible.

Step 8: Roast the Potatoes
Roast the potatoes in the oven for about 20 minutes without stirring. After 20 minutes, gently flip them using a thin spatula and continue roasting for an additional 15 to 20 minutes until they achieve a beautiful golden brown color and are tender when pierced with a fork.

Step 9: Finishing Touches
Once roasted, remove the potatoes from the oven. Sprinkle with a bit of flaky sea salt for flavor and gently toss them to distribute any pan drippings and seasonings evenly. The salt adds a delightful crunch and elevates the overall taste of your crispy roasted mustard potatoes.

Step 10: Serve and Enjoy
Serve the crispy roasted mustard potatoes hot, garnished with 2 tablespoons of finely chopped fresh parsley for a splash of color. If desired, include lemon wedges on the side for an extra zesty kick. These golden delights are sure to impress alongside any meal!

Crispy Roasted Mustard Potatoes Variations

Feel free to get creative with these delicious potatoes; they can be customized to suit your palate and dietary preferences!

  • Herb-Infused: Swap out dried thyme and rosemary for a mix of fresh herbs like dill, parsley, and basil for an aromatic variation. The freshness adds a lovely twist that's perfect for spring gatherings.

  • Spicy Kick: Add a pinch of cayenne pepper or a dash of hot sauce to the mustard mixture for some heat. This fiery flavor will awaken your taste buds, offering a delightful contrast to the creamy potatoes.

  • Cheesy Delight: Sprinkle grated Parmesan or crumbled feta over the potatoes in the last 5 minutes of roasting. This gives a cheesy crust that melts beautifully and deeply enhances the overall dish.

  • Vegan Twist: Replace honey or maple syrup with agave nectar and make your dish plant-based. It’ll keep the sweetness while ensuring everyone at the table can indulge.

  • Garlic Lovers: Add even more minced garlic to the mustard mix for a garlicky flavor explosion. Each bite will be infused with rich, savory goodness, making it irresistible for garlic enthusiasts.

  • Sweet and Sour: Drizzle balsamic glaze over the finished potatoes for a sweet and tangy flavor burst. This additional step adds complexity that beautifully complements the mustard.

  • Lemon Zing: Replace lemon juice with lime juice for a zesty twist. This subtle flavor change will brighten the dish and bring a vibrant taste to your table.

  • Crunchy Topping: Toss some panko breadcrumbs with olive oil and herbs before roasting, then sprinkle them on top of the potatoes in the last 10 minutes. This creates a delightfully crispy topping that’s simply addictive!

Make Ahead Options

These Crispy Roasted Mustard Potatoes are perfect for meal prep enthusiasts looking to save time on busy weeknights! You can prepare the mustard mixture and coat the halved potatoes up to 24 hours in advance, storing them in an airtight container in the refrigerator to maintain freshness. When you're ready to serve, simply take them out, let them sit at room temperature for about 15 minutes to take the chill off, and carefully transfer them to your preheated baking sheet. Roast as directed for crispy potatoes that are just as delicious as if you made them fresh! This method not only saves you precious time but also allows those flavors to meld beautifully.

Expert Tips for Crispy Roasted Mustard Potatoes

Choose the Right Potatoes: Use baby potatoes or small Yukon Gold for the best results; their creamy texture enhances the crunchiness of your crispy roasted mustard potatoes.

Don’t Skip Drying: After washing, pat the potatoes dry thoroughly. Excess moisture can lead to soggy potatoes instead of achieving that desired crispy texture.

Rest the Coated Potatoes: Allow the tossed potatoes to sit for 5–10 minutes before roasting. This brief resting time helps the flavors meld beautifully, making each bite more delicious.

Hot Baking Sheet: Always preheat your baking sheet in the oven. This ensures that the potatoes begin cooking immediately, achieving that lovely golden-brown crust.

Use Quality Mustard: The combination of Dijon and whole-grain mustard creates layers of flavor that take your dish to the next level. Experiment with other mustards to find your perfect taste.

Check for Doneness: Make sure to pierce the potatoes with a fork; they should be tender inside and beautifully crisp outside. Avoid over-roasting, as they can become dry.

Crispy Roasted Mustard Potatoes Recipe FAQs

How do I choose the best potatoes for this recipe?
Absolutely! I recommend using baby potatoes or small Yukon Golds for that creamy texture which enhances the crunchiness of your crispy roasted mustard potatoes. Look for firm potatoes without any dark spots or blemishes. If you're opting for larger potatoes, make sure to quarter them to ensure even cooking.

What is the best way to store leftover roasted potatoes?
Very! Store any leftover crispy roasted mustard potatoes in an airtight container in the fridge for up to 3 days. To reheat, place them in the oven at 375°F (190°C) for about 10-15 minutes until they're heated through and regain their crispy texture. Avoid microwaving as this can make them soggy.

Can I freeze crispy roasted mustard potatoes?
Of course! To freeze, allow the potatoes to cool completely after roasting. Spread them in a single layer on a baking sheet and freeze for 1-2 hours. Once solid, transfer them to a freezer-safe bag or container, and they’ll keep well for up to 2 months. When you’re ready to enjoy, reheat them in the oven at 400°F (200°C) for 20-25 minutes until crispy and heated through.

What should I do if my roasted potatoes aren't crispy?
If your potatoes are not achieving that crispy exterior, it might be due to excess moisture or overcrowding on the baking sheet. Make sure to dry the potatoes thoroughly before tossing them in the mustard mixture. Additionally, ensure they’re spread out in a single layer on the baking sheet to allow for proper air circulation.

Are there any dietary considerations for this recipe?
Absolutely! If you're concerned about allergies, the mustard components could pose an issue for some. Opt for gluten-free Dijon if you need that alternative. Also, check the olive oil for any allergy compatibility. If you're cooking for pets, be cautious as garlic and onion can be harmful to dogs and cats; it's best to keep their portions separate from servings prepared for them.
