Ingredients for mormon potatoes
Nine simple ingredients transform into golden, vinegar-kissed wedges that disappear at gatherings.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 3 lb | Cut into 1-inch wedges, skins on |
| Yellow Onions 🧅 | 1 whole | Sliced into 1/4-inch rounds |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for even coating |
| White Vinegar 💧 | ¼ cup | Distilled for best flavor |
| Kosher Salt 🧂 | 1 ½ tbsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground for brightness |
| Garlic Cloves 🧄 | 4 cloves | Minced for aromatic depth |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for fresh finish |
| Vegetable Oil 🫒 | 2 tbsp | High smoke point preferred |
| Granulated Sugar 🍚 | 1 tsp | Enhances caramelization |
The Russet potatoes are non-negotiable here—their high starch content gives you that perfect fluffy interior. Buy them fresh (not pre-cut) from the produce section at Whole Foods or your local grocery store, and cut them into even 1-inch wedges. Uneven pieces lead to uneven cooking. The onions? Sweet yellows like Vidalia caramelize best, but regular yellows work fine. I usually grab a bag from Trader Joe's—they're pre-sliced and ready to go, saving me time. For the butter, Plugrá or Land O'Lakes unsalted are my go-tos, but any cold, cubed butter will do. The key is keeping it cold until it hits the skillet.
No white vinegar? Apple cider vinegar works too—just use the same amount. Running short on fresh parsley? Dried parsley at one-third the amount gives a similar punch, though it won't be as vibrant. The sugar might seem odd, but it's what helps those edges get that deep golden caramelization. Brown sugar works in a pinch if you're out of granulated. For the garlic, I like to smash the cloves with the side of my knife before mincing—it releases more flavor. If you're prepping ahead, you can cut the potatoes and onions up to 24 hours early and store them in cold water in the fridge to keep them fresh.
The potatoes reheat beautifully—just pop them in a 350°F oven for 10-15 minutes until crispy again. They keep well in the fridge for 4 days if stored in an airtight container, but honestly, they rarely last that long. For meal prep, I portion them into individual containers with a sprinkle of salt so they stay crispy. The vinegar and butter combo means they won't get soggy, even after reheating. If you're making a big batch for a crowd, double the recipe—just use two large skillets to avoid overcrowding.

Step-by-step instructions for golden vinegar-roasted potatoes
This method transforms humble russets into crispy, tangy wedges with a buttery interior—no fuss, just flavor.
Prep and Parboil the Potatoes
Cut the 3 lb russet potatoes into 1-inch wedges, keeping the skins on for texture. Spread them on a baking sheet and toss with the 2 tbsp vegetable oil, 1.5 tbsp kosher salt, and 0.5 tsp black pepper. Roast at 425°F for 15 minutes to soften slightly—this prevents them from falling apart later.
While they roast, bring a large pot of salted water to a boil. Add the potatoes and parboil for 5 minutes until they're tender but still firm to the bite. Drain immediately and return them to the baking sheet. Here's the thing—parboiling ensures the centers stay fluffy while the edges crisp beautifully.
Build the Vinegar-Butter Glaze
In a small saucepan, combine the 0.25 cup white vinegar, 1 tsp granulated sugar, and sliced 1 whole yellow onion. Simmer over medium heat for 8-10 minutes until the liquid reduces by half and the onions soften. This creates a sweet-tangy base that caramelizes on the potatoes.
Remove from heat and stir in the 0.5 cup cold, cubed unsalted butter until melted. The butter should coat the back of a spoon—this is your glaze. Taste and adjust seasoning with more salt if needed. The sugar helps balance the vinegar's acidity while promoting browning.
Roast to Crispy Perfection
Return the parboiled potatoes to the oven and drizzle generously with the vinegar-butter mixture. Toss to coat evenly, then roast at 425°F for 25-30 minutes, stirring once halfway, until the edges are deep golden brown and crispy. You'll smell that buttery, tangy aroma filling your kitchen—this is your signal they're ready.
Watch for the caramelized spots forming on the edges. If they brown too quickly, tent with foil for the last 5 minutes to prevent burning. The potatoes should be tender inside with a crisp exterior that gives way slightly when pressed.
Finish with Aromatics and Serve
Remove the potatoes from the oven and immediately sprinkle with the minced 4 cloves garlic and chopped 0.25 cup fresh parsley. Toss gently to distribute evenly—the parsley adds freshness while the garlic infuses the final flavor. Let them rest for 2-3 minutes before serving to allow the juices to redistribute.
Serve immediately while still crispy. These potatoes deliver a perfect balance of tangy-sweet glaze, crispy edges, and creamy centers—each bite is a harmony of textures. The vinegar cuts through the richness of the butter, making every forkful bright and satisfying.
Pro Tips For Making Mormon Potatoes
- CUT POTATOES UNIFORM: Grab a knife and slice them all the same thickness—about ¼-inch thick. I learned this the hard way: uneven slices mean some potatoes turn to mush while others stay raw. A mandoline helps, but even a sharp knife works if you’re patient.
- SALT THE WATER: Add salt to the boiling water before the potatoes go in—about 1½ tablespoons for a big pot. I used to wait until later, and the potatoes always tasted bland. Salt early, and the flavor soaks in right from the start.
- BAKE COOL POTATOES: Let the potatoes cool for 10 minutes after boiling before baking. Sounds weird, but it works: hot potatoes steam instead of crisping. Cold potatoes brown faster and develop that perfect golden crust without turning soggy.
- VINEGAR LAST MINUTE: Drizzle the white vinegar right before serving—not while baking. The acid cuts through the richness of the butter, but if you add it too soon, the potatoes can turn bitter. A splash at the end keeps the balance sharp and bright.
Pro cooking tips for this recipe
Parboil for Perfect Texture
The key to foolproof fluffy centers is parboiling the potatoes for just 5 minutes before roasting. This step ensures they cook evenly without turning mushy. I use a large pot of boiling salted water—about 4 quarts—to fully submerge the wedges.
After draining, I pat them very dry with paper towels to remove excess moisture, which is critical for crispy edges. 🥔
Vinegar-Butter Glaze Magic
Don’t skip reducing the vinegar with onions and sugar—this creates the signature tangy-sweet glaze. Simmer until the liquid reduces by half (8-10 minutes) so the onions caramelize and the acidity mellows. Then, fold in cold cubed butter until it melts completely.
The sugar isn’t just for flavor; it helps the edges brown beautifully. I like to taste the glaze before drizzling—adjust salt here if needed. 💧
High Heat for Crispy Edges
Roast at 425°F for maximum crispiness, but don’t overcrowd the pan. I use a 12-inch cast-iron skillet for even heat distribution. Stir once halfway through cooking to ensure all sides get that golden crust.
If the potatoes brown too quickly, tent with foil for the last 5 minutes to prevent burning. The edges should be deep golden, almost caramelized, while the centers stay tender. 🔥
Rest Before Serving
Let the potatoes rest for 2-3 minutes after tossing with garlic and parsley. This allows the juices to redistribute, so every bite is creamy, not gummy. I also like to sprinkle a pinch of flaky sea salt (like Maldon) right before serving to elevate the flavors.
The contrast of crispy, creamy, and tangy makes these potatoes irresistible. ✨
Double Batch for Crowds
For gatherings, double the recipe but use two skillets to avoid overcrowding. I’ve learned the hard way—stuffing too many potatoes into one pan steams them instead of crisping.
If you’re short on time, parboil the potatoes ahead and store them in cold water in the fridge for up to 24 hours before roasting. Just drain and pat them dry before cooking. 💡
Reheating Like a Pro
Leftovers reheat best in a 350°F oven for 10-15 minutes until crispy again. Microwaving works in a pinch, but the texture suffers—it’ll be soft, not crispy. To keep them crispy longer, store them in a single layer in an airtight container with a paper towel to absorb moisture.
They’ll stay good for 4 days in the fridge. 🍽️

Frequently asked questions
Why do Mormon potatoes need to be parboiled?
The 5-minute parboil creates the perfect texture—fluffy centers and crispy edges. Without it, the potatoes can turn mushy or burn before cooking through. This step also helps them hold their shape during roasting.
Can I make this recipe without vinegar?
Yes, but the tangy flavor will be missing. Substitute with 1 tablespoon lemon juice or apple cider vinegar for a milder taste. The sugar is still important for caramelization—don't skip it! The potatoes will just taste less vibrant.
How do I keep these potatoes crispy when reheating?
Always reheat in a 350°F oven for 10-15 minutes—never microwave. Store in a single layer with a paper towel to absorb moisture. For extra crispiness, broil for 2-3 minutes at the end. Leftovers stay good for 4 days this way.
What's the best way to cut the potatoes for even cooking?
Use a sharp chef's knife and cut into 1-inch wedges with skins on. Keep pieces similar in size so they cook uniformly. For faster prep, buy pre-cut potatoes from stores like Trader Joe's. Uneven pieces lead to some bites being undercooked.
Can I make this recipe in an air fryer?
Toss parboiled potatoes with oil, salt, and pepper, then air fry at 400°F for 15-18 minutes, shaking halfway. After crisping, brush with the vinegar-butter glaze and air fry 5 more minutes. The texture will be slightly different but still delicious.
