Ingredients for jimmy's harborside delmonico potatoes
Eight essential ingredients transform simple potatoes into a restaurant-worthy side dish.
| Ingredient | Amount | Notes |
|---|---|---|
| Yukon Gold Potatoes 🥔 | 2 ½ lb | Medium size, cut into 1-inch chunks |
| Unsalted Butter 🧈 | ½ cup | Cold, cut into 1-inch cubes |
| White Vinegar 💧 | ½ cup | Distilled preferred for tang |
| Heavy Cream 🥛 | ¼ cup | Full-fat for creaminess |
| Salt 🧂 | 2 tsp | Kosher or sea salt |
| Fresh Thyme Leaves 🌿 | 1 tbsp | Or 1 tsp dried thyme |
| Fresh Parsley Leaves 🌿 | 2 tbsp | Chopped, for garnish |
| Garlic Cloves 🧄 | 2 cloves | Minced for flavor base |
| Black Peppercorns 🌶️ | ½ tsp | Freshly cracked |
| Vegetable Oil 🫒 | 2 tbsp | For greasing baking dish |
| Water 💧 | 4 cups | For parboiling potatoes |
The Yukon Gold potatoes are non-negotiable here—their waxy texture holds up perfectly to the parboiling and baking process. Look for firm, medium-sized potatoes at your local market or grocery store; the Whole Foods or Trader Joe's sections often carry the best quality. Avoid potatoes with sprouts or soft spots, as these won't crisp properly. The key is cutting them into even 1-inch chunks—this ensures consistent cooking. If you're short on time, Costco often sells pre-cut potatoes in the frozen section, though fresh is always better for texture. Fresh thyme and parsley elevate the dish, so grab a small bunch from the produce section—Penzeys carries excellent dried options if fresh isn't available, but fresh is ideal for that bright, herbal note.
No white vinegar? Apple cider vinegar works in a pinch, though it adds a slightly sweeter tang. Short on heavy cream? Half-and-half or whole milk will work, though the texture won't be as rich. The butter must be unsalted—adding salt later gives you full control over the dish's seasoning. Diamond Crystal kosher salt is my go-to for even distribution, but any fine sea salt will do. The garlic and peppercorns can be swapped for garlic powder and ground black pepper if you're in a hurry, though fresh is always preferred. For a vegan twist, replace the butter with olive oil and use coconut cream instead of heavy cream—just note the texture will be slightly different. The vegetable oil for greasing? Any neutral oil (like canola or grapeseed) works, but avoid flavored oils like olive.
Parboiled potatoes keep in the fridge for up to 2 days before baking—this is perfect for meal prep. Store them in an airtight container with a paper towel to absorb excess moisture. The baked potatoes reheat beautifully in a 350°F oven for 10-15 minutes, though they're best served fresh. For longer storage, the vinegar-infused baking liquid can be saved in a jar in the fridge for up to 1 week—just reheat gently before using. The crispy crust softens when reheated, so it's best enjoyed straight from the oven. Garnish with extra parsley right before serving to keep it vibrant. This dish makes 6 servings if doubled, so consider scaling up for gatherings—just increase the baking time by 10-15 minutes for larger batches.
Why You'll Love This Recipe

Step-by-step instructions for jimmy's Harborside Delmonico potatoes
Master this classic technique for potatoes with a crisp vinegar crust and tender pink centers.
Parboil the Potatoes for Even Cooking
Place the 2.5 lb yukon gold potatoes in a large pot and cover with the 4 cups water. Add 1 tsp of the 2 tsp salt to the water. Bring to a rolling boil over high heat and cook for exactly 8 minutes until the potatoes are slightly tender but still firm to the touch. This parboiling step is crucial—it ensures the potatoes cook evenly and prevents them from falling apart during baking.
Drain the potatoes immediately in a colander and rinse them under cold water for 30 seconds to stop the cooking process. Pat them completely dry with a clean kitchen towel. Any remaining moisture will prevent the butter from crisping properly later. Work quickly here—damp potatoes will result in a soggy crust instead of that signature crispy exterior.
Create the Vinegar-Butter Mixture for Crispy Crust
In a large mixing bowl, combine the 0.5 cup white vinegar and the 0.5 cup unsalted butter (cut into 1-inch cubes). Add the 2 cloves minced garlic, the remaining 1 tsp salt, and the 0.5 tsp freshly cracked black peppercorns. Mix with a wooden spoon until the butter is completely melted and the mixture is smooth and well combined.
This vinegar-butter mixture is what creates the iconic crispy crust. The acidity in the vinegar helps break down the potato starches, while the cold butter cubes melt and create pockets of air that crisp during baking. The garlic and pepper infuse flavor throughout the dish. If your butter isn't completely melted at this stage, don't worry—the residual coldness will help create that perfect crust texture.
Toss Potatoes in the Vinegar-Butter Mixture
Add the drained potatoes to the bowl and toss them gently but thoroughly with the vinegar-butter mixture. You want each potato piece to be fully coated—press down lightly to ensure the mixture penetrates the crevices. Let the potatoes sit in the bowl for 5 minutes while you prepare your baking dish. This resting time allows the vinegar to penetrate slightly and the potatoes to absorb some of the flavor.
While waiting, preheat your oven to 425°F. Grease a 9x13-inch baking dish with the 2 tbsp vegetable oil, using a paper towel to spread it evenly. This prevents sticking and ensures easy removal later. The oil also helps create that perfect golden crust when combined with the vinegar-butter mixture.
Layer and Bake for Perfect Texture
Transfer the potatoes to the prepared baking dish, spreading them out in a single layer. You may need to work in batches if your dish isn't large enough. Sprinkle the 1 tbsp fresh thyme leaves evenly over the top. Bake for 35-40 minutes, stirring once halfway through, until the edges are deep golden brown and the potatoes are tender when pierced with a fork.
This stirring step is important—it prevents the top layer from over-browning while the bottom remains undercooked. You'll know they're done when the crust is crisp and the potatoes give slightly when pressed but still have a firm bite in the center. The vinegar aroma should be noticeable but not overpowering—this indicates proper cooking.
Finish with Cream and Fresh Herbs
Remove the potatoes from the oven and let them cool for 5 minutes. In a small saucepan, heat the 0.25 cup heavy cream over medium-low heat until it just begins to simmer. Pour this warm cream evenly over the hot potatoes and toss gently to coat. Return the dish to the oven for 2-3 minutes to let the cream soak in and create a glossy finish.
Remove from the oven and immediately sprinkle with the 2 tbsp chopped fresh parsley leaves. The cream adds richness that balances the vinegar's tang, while the parsley provides a fresh finish. Serve immediately while the crust is still crisp. These potatoes are best enjoyed right out of the oven when the contrast between the crisp exterior and fluffy interior is at its peak.
Pro Tips For Making Jimmy'S Harborside Delmonico Potatoes
- Slice Evenly, No Fuss: Grab a sharp chef’s knife and cut the Yukon Golds into uniform ¼-inch slices—no need for a mandoline. Thicker pieces stay dense, thinner ones turn to mush; consistency means even cooking. I used to eyeball it and ended up with a pot of unevenly done potatoes. Save yourself the stress and measure with a ruler if you’re skeptical.
- Vinegar First, Then Cream: Toss the sliced potatoes in vinegar before adding the heavy cream—this keeps them bright and crisp, not soggy. I learned this after a batch turned dull and watery; the acid needs a head start. Stir the vinegar in like you’re dressing a salad, then add the cream later when you’re ready to simmer.
- Salt the Butter Hard: Mix half the total salt into the melted butter before adding it to the potatoes—this distributes flavor evenly and cuts down on mid-cooking adjustments. I used to salt the butter lightly, then panic-season the potatoes afterward. Trust the math: if the recipe calls for 1 tsp salt total, put ½ in the butter now.
- Low and Slow After Boil: Once the potatoes hit a simmer, immediately drop the heat to the lowest setting that keeps tiny bubbles dancing. High heat after boiling turns the cream grainy and the potatoes gluey. I’ve ruined three batches by being impatient—this recipe rewards patience, not speed.
Regional styles of this recipe
New England Clam Chowder Twist
In coastal New England, Delmonico potatoes often star in clam chowder as a hearty, comforting side. Replace the vinegar with ½ cup clam juice (or fish stock) and fold in 1 cup chopped clams or ½ cup clam chowder base (like Knorr) into the final cream mixture.
Add ½ tsp smoked paprika for depth, and top with crumbled bacon and green onions. The result? A creamy, briny twist that pairs perfectly with lobster rolls or haddock. 🦪
Southern-Style Buttermilk Biscuit Topping
For a Southern-inspired variation, skip the vinegar crust and bake the potatoes as directed, then top with a buttermilk biscuit mixture.
Mix 1 cup biscuit dough (like Pillsbury Grands) with 2 tbsp melted butter and 1 tbsp honey, crumble over the baked potatoes, and broil for 2-3 minutes until golden. The sweet-tangy contrast is pure Southern comfort food magic. Serve with honey butter for dipping. 🍯
Midwest Cheddar & Jalapeño Crunch
In the Midwest, sharp cheddar and jalapeños take center stage. After baking, sprinkle the potatoes with ½ cup shredded cheddar and 2 tbsp diced jalapeños, then broil for 1-2 minutes until the cheese melts.
The heat from the jalapeños cuts through the richness, while the cheddar adds a gooey, savory finish. Garnish with chopped scallions for freshness. This version is a crowd-pleaser at tailgate parties or BBQ spreads. 🌶️
Pacific Northwest Smoked Salmon Version
On the West Coast, smoked salmon elevates these potatoes to gourmet heights. After baking, top with 4 oz thinly sliced smoked salmon, 2 tbsp crème fraîche, and 1 tbsp capers. The smoky, salty flavors complement the vinegar crust beautifully.
Serve with lemon wedges for a bright finish. This version is a seafood lover’s dream and pairs perfectly with seared scallops or grilled halibut. 🍣
Texas-Style BBQ Potato Hash
For a Texan twist, bake the potatoes as usual, then toss them with ½ cup BBQ sauce (like Stark’s) and ¼ cup chopped red onions. Top with crumbled bacon and pickled jalapeños for a smoky, tangy kick.
Broil for 1-2 minutes to caramelize the onions. This version is ideal for brunch buffets or as a side to smoked brisket. 🔥
Vegan Olive Oil & Lemon Adaptation
For a plant-based version, replace the butter with ½ cup extra-virgin olive oil and the heavy cream with ½ cup coconut cream. Use ½ cup white wine instead of vinegar for a brighter flavor.
After baking, drizzle with a lemon-olive oil mixture (2 tbsp each) and garnish with fresh parsley. The result is a lighter, citrusy take that still delivers that crispy crust. 🌱

Frequently asked questions
Why do these potatoes need to be parboiled before baking?
Parboiling for exactly 8 minutes creates the perfect foundation—it softens the potatoes slightly while keeping their structure intact. This prevents them from falling apart during baking and ensures even cooking. The cold water rinse afterward stops the cooking process, so you get that signature contrast of crispy exterior and fluffy interior.
Can I use russet potatoes instead of Yukon Gold?
While you can use russets, they won't yield the same creamy texture. Yukon Golds are waxy potatoes that hold their shape better and have a naturally buttery flavor. For a russet alternative, cut them into ½-inch slices instead of chunks and reduce the baking time by 5 minutes to avoid dryness. The crust will still crisp, but the interior will be drier.
What's the secret to getting that perfect crispy crust?
The vinegar-butter mixture is key! The acidity in the vinegar breaks down potato starches, while the cold butter cubes create steam pockets that crisp during baking. Always use cold butter (cut into 1-inch cubes) and pat the potatoes completely dry before tossing. If your crust isn't crisp enough, try increasing the oven temperature to 450°F for the last 5 minutes of baking.
How do I store leftovers without making them soggy?
Cool the potatoes completely, then store them in an airtight container with a paper towel on top to absorb moisture. They'll keep well in the fridge for 3-4 days. To reheat, spread them on a baking sheet and warm at 375°F for 10-12 minutes until crispy again. Microwaving will make them rubbery—avoid at all costs!
Can I make these potatoes ahead of time for a dinner party?
Parboil and toss the potatoes in the vinegar-butter mixture up to 2 days ahead, then store them in the fridge. When ready to bake, spread them on a baking sheet and bake at 425°F for 30-35 minutes (they'll need less time since they're partially cooked). This is perfect for stress-free entertaining. Just add the cream and herbs right before serving.
