Mustard Potato Poppers Ingredients
For the Poppers

Step‑by‑Step Instructions for Mustard Potato Poppers
Step 1: Preheat the Oven
Begin by preheating your oven to 425°F (220°C). This high temperature will help achieve the perfect golden crispiness for your Mustard Potato Poppers. While the oven is heating, gather all your ingredients and equipment, including a baking sheet and parchment paper, to ensure a smooth cooking process.
Step 2: Prepare the Baby Potatoes
Next, take your baby potatoes and halve them evenly. This step is crucial for ensuring uniform cooking, which leads to a delightful crispy texture on the outside and a creamy interior. Aim for similar sizes to make sure they all roast evenly, and set them aside in a mixing bowl.
Step 3: Whisk the Mustard Mixture
In a large bowl, whisk together the olive oil, Dijon mustard, whole grain mustard, garlic powder, onion powder, salt, and pepper. Blend these ingredients thoroughly until you achieve a smooth mixture. The vibrant aromas will start to come together, enhancing the flavor profile of your Mustard Potato Poppers.
Step 4: Coat the Potatoes
Add the halved potatoes to the mustard mixture, making sure to toss them thoroughly until every piece is well coated. This ensures that the zesty flavors seep into the potatoes, creating a delicious snack. Take a moment to admire the lovely golden color of the coated potatoes before moving on.
Step 5: Arrange on the Baking Sheet
Now, arrange the coated potatoes in a single layer on a parchment-lined baking sheet. Make sure there’s enough space between each potato piece to allow for even cooking and browning. This layout will help achieve that crispy exterior that makes these Mustard Potato Poppers simply irresistible.
Step 6: Roast in the Oven
Place the baking sheet in the preheated oven and roast for 25 to 30 minutes. About halfway through, give the potatoes a good stir to ensure they brown evenly. You’ll know they’re done when they turn a beautiful golden brown and crisp to perfection, enticing you with their irresistible aroma.
Step 7: Cool and Garnish
Once roasted, remove the Mustard Potato Poppers from the oven and allow them to cool slightly. This brief cooling period helps enhance their crispy texture. Before serving, garnish with fresh parsley to add a pop of color and a hint of freshness that perfectly complements the dish.

Mustard Potato Poppers Recipe FAQs
What type of baby potatoes should I use?
I recommend using creamer or fingerling baby potatoes, as they have a creamy interior that contrasts beautifully with the crispy exterior. Look for potatoes that are firm with smooth skin and free of dark spots or blemishes for the best results.
How do I store leftover Mustard Potato Poppers?
To keep your Mustard Potato Poppers fresh, allow them to cool completely, then store them in an airtight container in the refrigerator for up to three days. If you’d like to keep them longer, consider freezing—just make sure they are well-cooled before placing them in a freezer-safe bag.
Can I freeze Mustard Potato Poppers? What’s the best method?
Absolutely! To freeze your Mustard Potato Poppers, first let them cool completely. Then, spread them out on a baking sheet in a single layer and freeze until solid, about 1-2 hours. Once frozen, transfer them to a freezer-safe bag, squeezing out as much air as possible. You can keep them frozen for up to 3 months. When you’re ready to enjoy them, reheat them directly from the freezer in an oven at 400°F (200°C) for 10-15 minutes until crispy.
What should I do if my Potatoes are not crispy?
If your Mustard Potato Poppers don’t turn out crispy, there could be a few reasons. Ensure you are halving the potatoes uniformly to promote even cooking. Also, make sure they’re spread out on the baking sheet instead of overcrowded; this allows for proper browning. If they still don’t crisp up, increase the roasting time slightly, checking every few minutes. Tossing them halfway through roasting is key too!
Are Mustard Potato Poppers safe for pets?
While Mustard Potato Poppers can be a tasty vegan treat for humans, the spices and mustard may not be suitable for pets. It’s best to avoid giving any seasoned or spiced foods to pets. If you wish to share, keep it simple: plain, cooked potatoes without salt or spices are a safer option.
What are the dietary considerations for Mustard Potato Poppers?
This recipe is vegan-friendly, making it perfect for plant-based diets. However, when selecting mustards, it’s essential to check the label for any animal derivatives, particularly in specialty brands, to ensure they align with your dietary preferences.
