These Mustard Potato Poppers have totally rescued last-minute meals at my place more times than I can remember. This trusty trick flips little potatoes into crazy tasty bites using just pantry basics and a burst of heat in the oven.
I came across this one while emptying out my fridge and it blew everyone away. Now my buddies beg for it at every movie night. They look simple but wow, the flavor really brings everyone back for more.
Tasty Ingredients
- Fresh parsley: Ends things with a zippy, green spark. Just use the fresh stuff—it makes a real difference.
- Salt and pepper: Balances everything. If you have sea salt, all the better for a bit of crunch.
- Onion powder: Pairs up with the garlic, adding a mellow sweet kick. You’ll miss it if you skip it!
- Garlic powder: Brings a toasty, deep hit of flavor. Newer garlic powder always pops more.
- Whole grain mustard: Crunchy mustard bits bring bursts of fun. Find the ones packed with seeds for best results.
- Dijon mustard: This is where the zip comes from. Smooth, tangy Dijon unites it all for that signature punch.
- Olive oil: Glues it all together and sends the texture over the top. Pick a decent extra virgin bottle to really boost taste.
- Baby potatoes: Little guys for ultimate snacking. Pick them firm and fresh to nail the creamy-crunchy combo.
Easy Step-by-Step
- Top It Off and Dish Out:
- Wait a few minutes after pulling them from the oven, toss on loads of chopped parsley while still warm, and hand 'em out hot from the tray.
- Bake to Gold:
- Slide everything into the heated oven and roast for nearly half an hour. Flip potatoes about halfway for even crunch and color on both sides.
- Arrange on Tray:
- Pour potatoes onto a parchment-covered baking pan, spread so none are piled up, and make sure their flat sides are touching the pan for max browning.
- Cover Potatoes in Mustard Sauce:
- Drop in your split potatoes and use your hands or a big spoon to get them super well coated. You want each chunk glossy and soaked with flavor.
- Whip Up Mustard Blend:
- Mix together your oil, both mustards, and seasonings in a big bowl. Make sure you whisk until everything’s smooth and every bit shines.
- Fire Up Your Oven:
- Crank the oven up to 425 Fahrenheit (220 Celsius) and give it time to properly heat, because you need it hot going in.

Whole grain mustard is the real secret here. Those little seeds pop in your mouth, and I always think of a family reunion where everyone wanted to know how I made them taste so good.
How to Store
Keep any leftover poppers in a container with a lid in the fridge and eat within three days. For best crispy results, reheat on a baking tray in a hot oven—skip the microwave, or you’ll get mushy potatoes. Fresh parchment every time keeps things from sticking.
Swaps and Switches
If you don’t have baby potatoes, cut big ones into little chunks. Out of Dijon? Basic yellow mustard will work, though it’s not as zingy. No parsley? Grab some dill or chives instead and sprinkle over at the end.

Serving Ideas
Goes great with roasted chicken, grilled steak, or makes a fun brunch side. Try serving with a tangy yogurt dip or toss them right into a grain salad. For parties, poke a toothpick in each and you’ve got the ultimate hand-held snack.
Tiny Bit of History
Potatoes and mustard have teamed up for ages in both French and Eastern European kitchens. People have been mixing that zippy, sharp flavor with potatoes since they landed on European tables. You’ll spot them everywhere—from market stalls to big family feasts—there’s just no wrong way to eat them.
Common Questions
- → How do I get potatoes super crispy?
Don’t crowd the pan, pop the potatoes in one layer, and crank up your oven. Flip them over midway so they cook up golden all around.
- → Can I swap in other potatoes?
Small Yukon Golds or fingerlings will totally work if you can’t find baby potatoes. Just watch them in the oven—they might bake a bit longer or shorter.
- → What herbs mix well with this?
Chuck a little oregano, rosemary, or thyme into your mustard spread for a fresh boost and some aroma.
- → How do I tame or kick up the heat?
Want it gentler? Use honey mustard instead of Dijon. If you like spice, put in some red pepper flakes or a dash of cayenne.
- → Any way to make it vegan?
Just check your mustards are vegan (most are), and skip butter or any extra dairy. That’s all you have to do.
- → Can I prep these in advance?
Honestly, they taste best right out of the oven. But if you need to reheat, just use a really hot oven to get that crunch back.
