What Kind of Potatoes Should I Use for Mustard Potato Poppers?

For this recipe, baby Yukon Gold or small yellow potatoes work beautifully. Their creamy texture on the inside contrasts perfectly with their crisped, mustard-glazed exterior. You want a waxy potato that holds its shape during roasting—steer clear of russets, which can get too fluffy and fall apart.

Ingredients for the Mustard Potato Poppers

Baby Yukon Gold Potatoes: These small, golden spuds are creamy on the inside and get deliciously crispy on the outside—perfect for bite-sized poppers.

Whole Grain Mustard: Brings bold tang and texture. It sticks to the potatoes and adds that unmistakable zippy flavor.

Dijon Mustard: Adds a smooth, sharp heat that balances the earthiness of the potatoes.

Unsalted Butter: Helps carry the mustard flavors and gives the poppers a rich, glossy coating.

Garlic Powder: For warmth and depth without overpowering the mustard.

Paprika: Adds smokiness and a pop of color.

Salt and Black Pepper: Essential for seasoning the potatoes just right.

Chopped Fresh Parsley (optional): Sprinkled at the end for a touch of freshness and color.

How To Make the Mustard Potato Poppers

Step 1: Prep and Boil the Potatoes

Start by placing your baby Yukon Gold potatoes in a pot of salted water. Bring to a boil and cook until just fork-tender, about 10–12 minutes. Drain and let them cool slightly before proceeding. This helps them crisp better when roasted.

Step 2: Smash and Arrange

Using the bottom of a glass or a potato masher, gently smash each potato to flatten slightly without breaking it apart. Place them on a parchment-lined baking sheet, giving each one space so they roast evenly.

Step 3: Make the Mustard Butter Glaze

In a small bowl, mix together the unsalted butter (melted), whole grain mustard, Dijon mustard, garlic powder, paprika, salt, and black pepper. Whisk until combined into a thick, flavorful glaze.

Step 4: Brush and Roast

Generously brush each smashed potato with the mustard butter glaze, coating all sides. Roast in a preheated oven at 425°F (220°C) for 25–30 minutes, flipping once halfway through. They should be golden, crispy, and caramelized.

Step 5: Garnish and Serve

Remove from the oven and sprinkle with chopped fresh parsley if using. Serve immediately while hot and crisp—they’re irresistible straight off the pan!

How to Serve and Store These Mustard Potato Poppers

These mustard potato poppers are best served hot and fresh from the oven. Their crispy edges and tangy glaze make them perfect on their own, but they also shine alongside grilled meats, burgers, or as part of a vegetarian spread. Pair them with a creamy dip like ranch or a garlicky aioli for extra indulgence.

If you have leftovers (which is rare!), store them in an airtight container in the fridge for up to 3 days. Reheat in the oven at 375°F to bring back the crispiness—a microwave just won’t do them justice!

Frequently Asked Questions

What kind of mustard is best for these poppers?

A mix of whole grain mustard and Dijon creates the perfect flavor balance—textured, tangy, and just a little sharp.

Can I use regular potatoes instead of baby ones?

You can, but make sure to cut them into smaller chunks and keep the skin on. Baby potatoes are ideal for their size and texture.

Can I make these ahead of time?

You can parboil and smash the potatoes a few hours ahead, then glaze and roast them just before serving for best results.

Are these poppers spicy?

Not really. Dijon mustard adds a slight kick, but it’s mild and balanced by the butter and paprika.

Can I air fry these instead of roasting?

Absolutely! Air fry at 400°F for 15–18 minutes, flipping halfway through. Just don’t overcrowd the basket.

What dips go well with these?

Think creamy: ranch, sour cream and chive, or even a honey mustard dip will complement them beautifully.
