Ingredients You’ll Need
Gather these simple items from your pantry and fridge:
- 2 lbs small to medium potatoes (Yukon Gold or new potatoes work best)
- 3 tablespoons olive oil (or avocado oil)
- 2 tablespoons Dijon mustard
- 1 tablespoon whole grain mustard
- 2 cloves garlic, minced finely
- 1 teaspoon dried rosemary (or 1 tablespoon fresh, chopped)
- 1/2 teaspoon salt (plus more for finishing)
- 1/4 teaspoon black pepper
- Pinch of red pepper flakes (optional, for a little heat)
Step-by-Step Roasting Magic
Follow these steps closely, especially the parboiling and crushing, for maximum crispness!
Step 1: Prep and Boil the Potatoes
1. Preheat your oven to a hot 425°F (220°C). Line a large baking sheet with parchment paper for easy cleanup.
2. Wash your potatoes thoroughly. If using larger potatoes, cut them into roughly uniform 1.5-inch chunks. If using small new potatoes, you can leave them whole.
3. Place the potatoes in a large pot and cover them with cold, salted water. Bring the water to a boil and cook until the potatoes are fork-tender but not falling apart—about 10 to 15 minutes. You want them tender on the inside but still holding their shape.
4. Drain the potatoes very well in a colander. Let them sit for about 5 minutes to steam dry. This is crucial for crispiness!
Step 2: The Secret Crush
1. Carefully transfer the drained, slightly cooled potatoes onto your prepared baking sheet.
2. Using the bottom of a sturdy glass or a potato masher, gently press down on each potato until it is slightly flattened or “crushed.” Don’t mash them into oblivion; you want the edges to fray and break slightly—this creates extra surface area for crisping!
Step 3: The Tangy Mustard Coating
1. In a small bowl, whisk together the olive oil, Dijon mustard, whole grain mustard, minced garlic, rosemary, salt, pepper, and red pepper flakes (if using). Mix until it forms a smooth, emulsified coating.
2. Drizzle this gorgeous mustard mixture evenly over the crushed potatoes on the baking sheet.
3. Use your hands or a spatula to gently toss the potatoes right on the sheet until every crushed edge is lovingly coated in the mustard mixture. Make sure they are spread out in a single layer—no overcrowding!
Step 4: Roasting to Perfection
1. Place the baking sheet in the preheated oven. Roast for 35 to 40 minutes.
2. About halfway through (around the 20-minute mark), carefully flip the potatoes using a spatula so they brown evenly on the other side.
3. Continue roasting until they are deeply golden brown, wonderfully crunchy on the outside, and fluffy inside.
4. Remove from the oven, sprinkle with a little extra sea salt if desired, and serve immediately!
Serving Suggestions
These Crispy Roasted Mustard Potatoes are fantastic as they are, but here are a few ways to elevate the experience:
- Herbaceous Finish: Sprinkle with fresh parsley or chives just before serving for a pop of color.
- Cheesy Goodness: A light dusting of grated Parmesan cheese during the last 5 minutes of roasting adds salty sharpness.
- Dipping Fun: Serve alongside a simple lemon-dill yogurt dip or a bit of spicy aioli.
Tips for Customization & Variations
Want to mix it up? These potatoes are very forgiving!
- Spice Level: Swap out the Dijon for a spicy brown mustard or add a teaspoon of smoked paprika for a smoky depth.
- Herb Swap: Thyme pairs wonderfully with mustard. Try using dried thyme instead of rosemary.
- Vinegar Zing: For an extra bright flavor, toss the potatoes with 1 teaspoon of apple cider vinegar right after they come out of the oven.

Frequently Asked Questions (FAQs)
Q: Can I use sweet potatoes instead of white potatoes?
A: You certainly can! Sweet potatoes are delicious roasted, but they cook faster and caramelize more easily. Reduce the initial boiling time slightly, and check them after 25 minutes in the oven.
Q: Why do I need to crush the potatoes?
A: Crushing creates rough, jagged edges. When these edges hit the hot oven air and oil, they become incredibly crisp, giving you that amazing texture contrast between the crunchy outside and the soft inside.
Q: Can I use dried herbs instead of fresh?
A: Yes, absolutely! The recipe calls for dried rosemary. If you are using fresh rosemary, use about 1 tablespoon, roughly chopped.
Q: How do I store leftovers?
A: Store any leftovers in an airtight container in the refrigerator for up to 3 days. To revive the crispness, reheat them in a toaster oven or a hot oven (400°F) for 8-10 minutes, rather than microwaving, which will make them soggy.
Enjoy making these incredibly flavorful and crispy bites! Happy roasting!
