Step‑by‑Step Instructions for Crispy Whole30 Mustard Roasted Potatoes
Step 1: Preheat and Prepare
Begin by preheating your oven to 400°F (200°C). While it’s heating, prepare a baking sheet by lightly spraying it with oil or covering it with parchment paper. This will help achieve that coveted crispy exterior on your Roasted Herb Mustard Potatoes.
Step 2: Create the Flavor Mixture
In a mixing bowl, combine the ghee, stone-ground mustard, minced garlic, fresh rosemary, salt, and pepper. Stir these ingredients together until they form a well-blended mixture, ensuring that the aromatic garlic and zesty mustard are evenly distributed. This flavorful base will infuse your potatoes with incredible taste.
Step 3: Coat the Potatoes
Take your small potatoes and add them to the bowl with the ghee-mustard mixture. Toss the potatoes thoroughly, making sure each one is generously coated in the mixture. This step is crucial for ensuring that your Crispy Whole30 Mustard Roasted Potatoes absorb all the delicious flavors as they bake.
Step 4: Arrange on Baking Sheet
Transfer the coated potatoes to the prepared baking sheet, arranging them cut-side down for optimal crispiness. This allows the flat surfaces to get golden brown and crunchy in the oven. Spread them out evenly to prevent overcrowding, which ensures even roasting.
Step 5: Bake for Initial Cooking Time
Place the baking sheet in the preheated oven and bake the potatoes for 15 minutes. This initial cooking time allows them to soften while developing a lovely golden-brown crust on the cut sides, setting the stage for that perfect texture you desire.
Step 6: Flip and Continue Baking
After the first 15 minutes, carefully remove the baking sheet from the oven. Use a spatula or tongs to flip each potato to the other side. Return them to the oven for another 15 minutes, or until they are tender inside and nicely crisp on the outside, ensuring your Crispy Whole30 Mustard Roasted Potatoes are perfectly cooked.
Step 7: Garnish and Serve
Once the potatoes are done, remove them from the oven and allow them to cool for a couple of minutes. For a fresh touch, sprinkle chopped fresh parsley over the top before serving. These Roasted Herb Mustard Potatoes are now ready to be enjoyed as a delicious side dish, perfect for any meal!

Expert Tips for Roasted Herb Mustard Potatoes
Uniform Sizing: Ensure potatoes are cut into similar sizes for consistent cooking. Uneven pieces may result in some being overcooked while others remain underdone.
Opt for Fresh Ingredients: Use fresh garlic and rosemary for a more potent flavor. Dried herbs will work, but fresh brings a vibrant touch to your roasted potatoes.
Avoid Overcrowding: Spread potatoes evenly on the baking sheet. Overcrowding can lead to steaming instead of roasting, preventing those crispy edges you desire in roasted herb mustard potatoes.
Proper Storage: Store leftovers in an airtight container for up to 3 days. Reheat in the oven to maintain crispiness; microwaving may leave them soggy.
Double the Batch: If cooking for a crowd, don’t hesitate to double the recipe! Just use two separate baking sheets to maintain that heavenly, crispy texture.

Crispy Whole30 Mustard Roasted Potatoes Recipe FAQs
What type of potatoes should I use for this recipe?
Absolutely! For the best results, I recommend using small potatoes like fingerling, golden, or red potatoes. These types tend to be creamy and provide a delightful texture when roasted. Aim for 1 to 1.5 pounds to ensure a hearty serving.
How should I store leftover roasted potatoes?
Store your leftover roasted herb mustard potatoes in an airtight container in the fridge for up to 3 days. This keeps their flavor and freshness intact. When you’re ready to enjoy them again, simply reheat in the oven at 350°F (175°C) for about 10-15 minutes to crisp them back up.
Can I freeze these roasted potatoes?
Yes, you can freeze them! Start by letting the roasted potatoes cool completely. Then, lay them in a single layer on a baking sheet and place them in the freezer for about 2 hours until frozen solid. After that, transfer them to a freezer-safe bag. They can be stored for up to 3 months. When you’re ready to eat, thaw them in the fridge overnight and reheat in the oven to regain their delicious crispiness.
What should I do if my potatoes aren’t crispy?
If your potatoes end up soft or soggy, there are a couple of things you can do. First, ensure that you didn’t overcrowd the baking sheet, as this can lead to steaming. If you find yourself in this situation, try again by using multiple baking sheets for even roasting. Additionally, for next time, make sure to cut the potatoes into uniform sizes so they cook evenly. Lastly, always flip the potatoes halfway through baking to allow for crisping on both sides.
Are these potatoes safe for those with specific dietary restrictions?
Absolutely! These Crispy Whole30 Mustard Roasted Potatoes are not only Whole30 compliant but also paleo and gluten-free. That means they’re a great choice for anyone looking for a healthy side dish free from grains and dairy.
