Side Dishes
This Montana potatoes recipe delivers crispy herb-buttered wedges with a vinegar-kissed crust that's become a staple in my kitchen during Big Sky season. The secret lies in the balance of fresh rosemary, garlic, and a splash of apple cider vinegar that creates that signature tangy crunch.
I first made these after a long day hiking in Glacier National Park, when I needed something hearty yet simple to pair with grilled steak.
The technique is straightforward but precise: thick-cut potatoes are roasted until tender, then tossed in melted butter infused with herbs and vinegar while still piping hot. This ensures the crust forms instantly, locking in those aromatic flavors.
What sets these apart is the vinegar—it cuts through the richness while adding a bright, almost citrusy depth that's characteristic of Montana mountain cooking.
By the time these wedges emerge from the oven, you'll have golden-brown potatoes with crispy edges and tender centers, coated in a fragrant herb-butter glaze. The vinegar-kissed crust adds a satisfying crunch that disappears with each bite, revealing the warm, buttery potato underneath.
These are perfect for game day gatherings, summer picnics, or as a hearty side to any steakhouse-style meal.
Pro tip: For extra flavor, use local Montana huckleberries if you can find them—they add a subtle tartness that complements the vinegar beautifully. The recipe scales easily, so you can serve a crowd without sacrificing quality.
Let's get cooking with these Montana-style wedges that taste like a taste of the Rockies.
Ingredients for montana potatoes
Thick-cut potatoes meet herb butter and vinegar for crispy, tangy wedges that taste like Montana mountain cooking.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 2 ½ lb | Thick-cut, cut into 1.5-inch wedges |
| Unsalted Butter 🧈 | ½ cup | Cold, cut into 1-inch cubes |
| Fresh Rosemary 🌿 | ¼ cup | Finely chopped, stems removed |
| Garlic Cloves 🧄 | 4 cloves | Minced for butter infusion |
| Apple Cider Vinegar 🍏 | 2 tbsp | Raw, unfiltered preferred |
| Sea Salt 🧂 | 1 ½ tsp | Coarse grain for crust |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked for heat |
| Olive Oil 🫒 | 2 tbsp | Light, for tossing wedges |
| Montana Huckleberries 🍇 | ¼ cup | Optional, for extra tartness |
The potatoes are everything here. Russets are ideal—they're starchy enough to crisp but hold up to roasting. Grab the biggest ones at the store; you want those thick wedges. Local grocery stores often carry them in the fall, but if you're out of season, any russet will do. For the rosemary, farmers markets have the freshest, but the grocery store stuff works if it's green and fragrant. Skip the dried—it's not the same. And if you're near Glacier National Park, hit up a roadside stand for those Montana huckleberries—they're worth the hunt.
No apple cider vinegar? White wine vinegar or lemon juice works in a pinch, but it won't have that same rich, fruity depth. Short on rosemary? Fresh thyme or sage at half the amount adds a different but delicious twist. The butter needs to be cold when you cube it—take it out of the fridge 20 minutes before using so it softens just enough to melt into the potatoes. For extra crispiness, toss the wedges in a little cornstarch before roasting. Trust me, it's a game changer.
These wedges reheat beautifully—just pop them in a 350°F oven for 10 minutes until crispy again. Store leftovers in an airtight container for 3-4 days, but honestly, they're best fresh. The herb butter keeps well in the fridge for 1 week if you make extra—just press plastic wrap directly on top to keep it fresh. Freeze the wedges before tossing in the butter if you want to prep ahead; they'll crisp up just fine.

Step-by-step instructions for herb-buttered potato wedges
Here's how to create crispy, flavorful wedges that balance rich butter with bright vinegar and fresh herbs.
Prep and Parboil the Potatoes
Cut the 2.5 lb russet potatoes into 1.5-inch wedges, keeping the skin on for texture. Arrange them in a single layer on a rimmed baking sheet and toss gently with the 2 tablespoons olive oil and 1 teaspoon of the 1.5 teaspoons sea salt. This prevents sticking during cooking.
Bring a large pot of water to a boil and add the potatoes. Cook for 5 minutes until they're slightly tender but still firm to the bite. Drain immediately in a colander and return them to the baking sheet. Pat them dry thoroughly with paper towels—this is crucial for crispy skin later. I like to spread them out in one layer so they dry evenly.
Infuse the Butter with Garlic and Rosemary
In a small bowl, combine the 0.5 cup unsalted butter, 0.25 cup finely chopped fresh rosemary, and 4 minced garlic cloves. Mix well and let it sit at room temperature for 10 minutes while you finish prepping the potatoes. This allows the garlic to soften and infuse the butter with flavor.
Spread the butter mixture evenly over the dried potato wedges, pressing gently so it adheres to every surface. The butter should melt slightly from the residual heat of the potatoes, creating a flavorful coating. Sprinkle with the remaining 0.5 teaspoon sea salt and 0.5 teaspoon ground black pepper.
Roast Until Golden and Crispy
Preheat your oven to 425°F. Arrange the potato wedges in a single layer on a parchment-lined baking sheet, leaving space between them for airflow. Roast for 25 minutes, then flip each wedge carefully with tongs. Return to the oven and roast another 20-25 minutes until the edges are deep golden brown and the potatoes are tender when pierced with a fork.
Watch closely during the last 5 minutes—this is when they develop that perfect crispy crust. If they're browning too quickly, tent loosely with foil to prevent burning. The wedges should be fork-tender inside with a crisp exterior that shatters slightly when you press it.
Finish with Vinegar and Optional Huckleberries
Remove the wedges from the oven and immediately drizzle with the 2 tablespoons apple cider vinegar. Toss gently to distribute evenly—the acidity cuts through the richness of the butter and brightens all the flavors. The vinegar will sizzle slightly from the residual heat, creating a beautiful crust.
For extra tartness, sprinkle the 0.25 cup montana huckleberries over the top and toss again. The berries add a beautiful contrast in color and a burst of flavor that pairs perfectly with the herbed butter. Serve immediately while the wedges are still crispy and warm.
Pro Tips For Making Montana Potatoes
- CUT POTATOES EVENLY: Grab a chef’s knife and slice those Russets thin—about ¼-inch thick. I learned this the hard way: thicker slices stay undercooked inside while burning outside. If your knife’s not sharp, use a mandoline (safety first) or ask the butcher to slice them—yes, really.
- SALT THE WATER LIKE THE SEA: Toss in 2 tablespoons of salt before adding the potatoes—this recipe isn’t shy about flavor. Under-salted water means bland edges, and no one wants that. Trust me, the butter and vinegar won’t overpower it; they’ll just highlight the crisp.
- DON’T SKIP THE VINEGAR REST: After roasting, let those potatoes sit in the vinegar-butter-garlic mix for at least 10 minutes—longer if you’re patient. I used to rush this, and the acid never really penetrated. Now? The rosemary and garlic cloves marinate into the spuds, making every bite taste like a hug.
- USE COLD BUTTER FOR CRISP: Chill the butter before mixing it with the vinegar and garlic—just 15 minutes in the fridge does the trick. Cold butter coats the potatoes better and crisps up faster when roasted. Hot butter? It’ll steam the potatoes instead of browning them. (Yes, I’ve done that too.)
Troubleshooting perfect results
Potatoes Too Soft
If your wedges turn out mushy instead of crispy, you likely didn’t dry them thoroughly after parboiling. Pat them with paper towels until completely dry—even a little moisture will steam the potatoes instead of crisping them.
Another common mistake is overcrowding the baking sheet, which traps steam. Arrange wedges in a single layer with ½-inch gaps between them for proper airflow. 🥔
Butter Not Melting
Cold butter cubes won’t melt into the potatoes, leaving them bland. Take your unsalted butter out of the fridge 20 minutes before using so it softens but stays firm enough to hold shape.
For extra insurance, spread the butter mixture over the hot wedges right after parboiling—the residual heat will help it melt evenly. If it still doesn’t melt, try microwaving the butter for 10 seconds before spreading.
Uneven Browning
If some wedges brown faster than others, rotate the baking sheet halfway through roasting for even heat distribution. Another trick is to flip all wedges at once after the first 25 minutes—this ensures consistent browning.
If your oven runs hot, tent the tray with foil during the last 5 minutes to prevent burning while still achieving crispiness. A light-colored baking sheet also helps reflect heat more evenly than dark pans.
Vinegar Not Adding Tang
The apple cider vinegar should sizzle slightly when drizzled over hot wedges, but if it just sits there, your potatoes aren’t hot enough. Toss the wedges immediately after removing from the oven while they’re still piping hot.
For extra tang, use raw, unfiltered vinegar—it has more flavor depth than processed versions. If you’re short on time, a splash of lemon juice works in a pinch, though it won’t have the same rich complexity. 🍏
Herbs Tasting Bitter
Fresh rosemary should add aroma, not bitterness. If your herbs taste harsh, they’re likely overcooked. Remove rosemary stems before chopping and use only the needle-like leaves. For milder flavor, pulse the rosemary in a food processor for 3-4 seconds instead of chopping by hand—this releases oils without over-releasing bitterness.
If you’re using dried herbs, reduce to half the amount (¼ tsp instead of ½ tsp) and add them after roasting to preserve freshness.
Leftovers Losing Crisp
Reheating wedges in the microwave kills crispiness, but you can revive them in the oven. Spread leftovers on a baking sheet and bake at 400°F for 8-10 minutes until golden again. For extra crisp, toss cold wedges with 1 tsp cornstarch before reheating.
Store leftovers in an airtight container at room temp for up to 2 hours or refrigerate for 3-4 days—but honestly, they’re best eaten fresh while crispy. ⏰

Frequently asked questions
What makes these Montana-style wedges different from regular potato wedges?
The secret lies in the apple cider vinegar and fresh rosemary—the vinegar creates a tangy crust that cuts through the butter's richness, while the rosemary adds a piney aroma unique to mountain cooking. The parboiling step ensures crispy edges without drying out the centers, a hallmark of this recipe.
Can I use sweet potatoes instead of russets?
Sweet potatoes work, but they have a different texture and flavor. Their natural sweetness pairs well with the vinegar, but they won't crisp as dramatically as russets. If you try them, reduce the roasting time by 5-10 minutes since they cook faster. For best results, stick with russets for that classic Montana wedge experience.
How do I adjust this recipe for a crowd?
Double the ingredients and use two baking sheets. For 8 servings, increase potatoes to 5 lb, butter to 1 cup, and rosemary to 0.5 cup. Use two ovens if possible, or stagger roasting times in one oven. Keep the vinegar and salt ratios the same—2 tbsp vinegar per 2.5 lb potatoes and 1.5 tsp salt per 2.5 lb.
What’s the best way to serve these wedges?
These wedges pair perfectly with grilled steak, baked chicken, or even as a hearty appetizer with blue cheese dip. For a Montana twist, serve with huckleberry BBQ sauce or a side of local honey to balance the vinegar's tang. They're also great cold in salads or sandwiches the next day.
Can I make this recipe ahead of time?
Prep the wedges up to 24 hours ahead—parboil, dry, and store them in the fridge in an airtight container. Roast them straight from the fridge (add 5-10 extra minutes to the cooking time). For the butter mixture, make it 1 day ahead and store it in the fridge. Toss the wedges with the butter just before serving to keep them crispy.
