Ingredients for mormon potatoes

Six simple ingredients create this legendary buttery, tangy potato side that steals every dinner show.

The potatoes are the star—Russets are non-negotiable here. They’re waxy and hold shape perfectly, creating that signature fluffy interior. Buy them fresh from the grocery store’s produce section (not the pre-bagged bins) for the best texture. If you can’t find Russets, Yukon Golds work in a pinch, but they’ll be slightly creamier. The secret to the golden crust? Cold butter—don’t melt it first, or you’ll lose that crispy magic. I always grab Land O’Lakes unsalted because it’s consistent, but any good-quality butter works. For the vinegar, White House brand is my go-to—it’s reliable and affordable, and the flavor is clean.

No white vinegar? Apple cider vinegar works too, but it’ll add a slight sweetness that changes the flavor profile. Fresh rosemary is ideal, but dried rosemary at half the amount gets you close if you’re in a hurry. The garlic can be pre-minced from a jar (I won’t judge), but fresh has way more punch. For the olive oil, Kirkland Signature is my budget-friendly favorite—it’s high-quality without breaking the bank. If you’re feeling fancy, extra-virgin olive oil adds a fruity note that pairs beautifully with the vinegar. The butter should be cubed into 1/2-inch pieces—this ensures even coating and maximum crispiness.

These potatoes reheat like a dream—just pop them in a 350°F oven for 10 minutes to revive that crispy crust. They keep well in the fridge for 4-5 days in an airtight container, but honestly, they’re even better the next day as the flavors meld. For meal prep, I portion them into individual serving containers so they’re ready to grab and go. The vinegar aroma fades slightly over time, so if you’re making these ahead, add a splash of fresh vinegar when reheating to bring back that tangy kick.

Step-by-step instructions for buttery vinegar roast potatoes

This golden, crispy potato dish is all about the magic of acid and fat working together—here's how to nail it every time.

Start by cutting the 3 lb russet potatoes into 1-inch chunks—keep them uniform so they cook evenly. Place them in a large pot and cover with cold water by about 1 inch. Add the 1.5 tbsp kosher salt and bring to a boil over medium-high heat. Once boiling, reduce to a gentle simmer and cook for 8-10 minutes until the edges are just barely tender when pierced with a fork.

This parboiling step is crucial—it jumpstarts the cooking process and prevents the potatoes from turning mushy in the oven. Drain them well in a colander, then give them a vigorous shake to remove excess water. The drier they are, the crispier they'll become later. I like to spread them on a clean kitchen towel and pat them dry with another towel—this extra step makes all the difference for that perfect golden crust.

In a very large bowl (or the bowl of a stand mixer), combine the drained potatoes with the 0.25 cup white vinegar and 0.25 cup chopped fresh rosemary. Toss them thoroughly with your hands or a wooden spoon—you want every potato coated in that tangy, herby mixture. The vinegar might seem like an odd ingredient, but it's what creates that signature crispy exterior while keeping the insides fluffy.

Let the potatoes sit in the bowl for 10 minutes while you prep the oven. This gives the vinegar time to work its magic, breaking down the starches slightly and prepping them for that incredible texture. Don't skip this step—it's what separates good roasted potatoes from extraordinary ones. While you wait, preheat your oven to 425°F with the rack positioned in the middle position.

In a separate bowl, melt the 0.5 cup unsalted butter and 2 tbsp olive oil together. The butter should be fully melted but not hot—just warm enough to coat the potatoes. Add the 4 cloves minced garlic and 0.5 tsp ground black pepper to the melted butter mixture and stir well. This aromatic blend is what will infuse the potatoes with incredible flavor.

Now, transfer the potatoes from the vinegar mixture to the butter bowl and toss them until every surface is completely coated. You'll know it's working when the potatoes start looking glossy and golden. The butter and oil will create that legendary crispy crust while keeping the insides tender. Don't be shy with the tossing—get into those chunks and make sure they're all well-coated. This is where the magic happens!

Spread the buttery potatoes evenly on two large rimmed baking sheets in a single layer—this ensures maximum crispiness. Roast them in the 425°F oven for 40-45 minutes, flipping them halfway through (after 20-25 minutes) for even browning. The potatoes are done when they're deep golden brown with a crisp exterior and a fork slides in easily with just a little resistance.

Here's the secret: resist the urge to peek! Every time you open the oven door, you lose heat and steam, which can make your potatoes less crispy. If you're worried about burning, just give them a quick stir at the 30-minute mark instead of flipping. The aroma filling your kitchen will tell you they're ready—it's one of the most incredible smells in cooking! When they're done, transfer them to a serving platter immediately while they're still hot and crisp.

Wine and beer pairings for this mormon potatoes

Classic Wine Pairings

For these tangy, buttery potatoes, a crisp Sauvignon Blanc from New Zealand or France is my go-to choice. The bright acidity in wines like Cloudy Bay Sauvignon Blanc cuts through the richness while complementing the vinegar’s tang.

Look for notes of citrus and green apple—these flavors mirror the herbaceous rosemary and buttery crust. Serve it slightly chilled (45-50°F) to enhance its refreshing qualities. 🍷

Light Beer Matches

A Belgian witbier or German Helles Lager pairs surprisingly well with these potatoes. The citrusy, spicy notes in witbiers like Hoegaarden enhance the vinegar’s brightness, while a light lager like Weihenstephaner Original keeps the meal balanced without overpowering the dish.

For a local option, try a American pale ale with subtle hop bitterness—just avoid heavy IPAs that might clash with the delicate flavors. 🍺

Unexpected Cider Option

Don’t overlook dry hard cider as a pairing—especially if you prefer something fruity but not overly sweet. A French cider like Domaine Dupont with its crisp apple and pear notes bridges the gap between the potatoes’ tang and buttery richness.

The slight effervescence also cleanses the palate between bites. For a sweeter option, a dry sparkling cider works beautifully too. 🍏

Regional Utah Twist

If you’re serving these in Utah or the Intermountain West, a local apple wine from a small vineyard can be a fun surprise. The Utah Wine Company’s Riesling offers a balance of sweetness and acidity that pairs wonderfully with the potatoes’ savory depth.

For a non-alcoholic option, a sparkling apple cider from a local orchard adds a festive touch. 🗺️

Bold Red Alternatives

If you prefer red wine, a light Pinot Noir with bright acidity—like a Willamette Valley Oregon Pinot—works surprisingly well. The red fruit notes complement the rosemary, while the acidity matches the vinegar’s tang.

Avoid heavy Cabernets or Syrahs, as their tannins can overpower the dish’s delicate flavors. Decant for 30 minutes to soften any remaining tannins. 🍇
