Ingredients for jimmy's harborside delmonico potatoes
Thick potato slices, butter, vinegar, and herbs—just five key elements for restaurant-worthy Delmonico potatoes.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 2 ½ lb | Large, uniform size, peeled |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for frying |
| Fresh Thyme Leaves 🌿 | 1 tbsp | Finely chopped, stems removed |
| Fresh Parsley Leaves 🌿 | 1 tbsp | Finely chopped, stems removed |
| White Vinegar 💧 | ¼ cup | Distilled, for crisping |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | For boiling water |
| Diamond Crystal Kosher Salt 🧂 | 1 tsp | For seasoning after frying |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For pan-frying |
| Fresh Lemon Juice 🍋 | 1 tbsp | Brightens final flavor |
| Heavy Cream 🥛 | ¼ cup | Optional, for extra creaminess |
| Ground White Pepper 🌶️ | ¼ tsp | Freshly ground for elegance |
The potatoes are everything here. Russet potatoes are ideal—their high starch content creates that signature creamy interior. Grab the largest ones you can find at Whole Foods or your local market, where they're usually sold in the produce section near the onions. Skip the pre-cut bags; uniform slices are key for even cooking. If you're feeling fancy, organic Russets from a farm stand have even better flavor. Peeled and sliced into 1/2-inch thick rounds, these will transform into tender, fluffy slices with crispy edges. Trust me, the extra time peeling is worth it for that restaurant-quality look.
No fresh thyme? Dried thyme at one-third the amount works, but fresh is worth hunting down at Trader Joe's or even your grocery store's herb section. Running low on vinegar? Apple cider vinegar gives a slightly sweeter note, but distilled keeps it classic. The butter matters too—European-style unsalted butter like Plugrá or Kerrygold adds richness, but regular unsalted works fine. For the pan-fry, if you're short on olive oil, neutral oil like avocado or grapeseed keeps from overpowering the potato flavor. And that splash of lemon juice? Freshly squeezed makes all the difference—bottled just won't cut it.
These potatoes reheat beautifully—just 5 minutes in a 375°F oven with a splash of water to keep them moist. Store leftovers covered in the fridge for up to 3 days, though they're best served fresh. For a crowd, double the batch—they disappear fast. Pro tip: Make the vinegar-butter mixture ahead and store it in the fridge for up to 1 week. The herbs lose potency after that, so keep them fresh until you're ready to fry.

Step-by-step instructions for jimmy's harborside Delmonico potatoes
Here's the method that delivers those legendary crisp crowns over tender, creamy centers—every time.
Parboil the Potatoes for Structural Integrity
Place the 2.5 lb Russet Potatoes in a large pot and cover with cold water by about 2 inches. Add 1.5 tsp Diamond Crystal Kosher Salt and bring to a boil over high heat. Once boiling vigorously, reduce to a gentle simmer and cook for exactly 12 minutes. This initial cook builds structural integrity while keeping the centers firm for that signature creamy finish.
I use a timer and stir the potatoes once halfway through to prevent sticking. The key is maintaining an even gentle simmer—not a rolling boil, which would cook them unevenly. When done, drain immediately and let them rest in the colander for 2 minutes to evaporate excess surface moisture. This step prevents the potatoes from steaming in the butter later, which would make them soggy.
Fry in Butter for Crispy Crowns
In a 12-inch cast-iron skillet, melt 0.5 cup Unsalted Butter over medium heat until it foams but doesn't brown. Add the drained potatoes in a single layer, arranging them cut-side down in concentric circles. Cook for 15 minutes, turning them once when the bottoms develop golden-brown spots and the edges begin to crisp.
Here's where the magic happens: the butter should be foamy but not browned, and the potatoes should develop a deep golden crust on the bottom. If you see the butter starting to brown too quickly, reduce the heat slightly. The goal is crispy bottoms while maintaining tender centers. After turning, continue cooking for another 10-12 minutes until the tops are also golden brown and the potatoes are fork-tender when pierced.
Acid Bath for Tangy Crispness
Remove the skillet from heat and immediately pour 0.25 cup White Vinegar evenly over the potatoes. Let them sit for exactly 3 minutes—this acid bath neutralizes any bitterness from the butter and creates that signature tangy crispness on the crowns. Don't skip this step; it's what makes these potatoes truly special.
While they're steaming in the vinegar, use a fork to gently fluff the potatoes, creating those signature ruffled crowns. The vinegar will also help set the crisp texture. After the 3 minutes, carefully drain the vinegar (you can save it for dressings or marinades) and return the skillet to low heat for 2 minutes to evaporate any remaining moisture.
Finish with Herbs and Creamy Emulsion
Remove the skillet from heat and stir in 1 tbsp Fresh Thyme Leaves, 1 tbsp Fresh Parsley Leaves, and 1 tbsp Fresh Lemon Juice. The herbs should wilt slightly, releasing their aromatic oils. Then, off the heat, slowly whisk in 0.25 cup Heavy Cream and 0.25 tsp Ground White Pepper until fully incorporated. The residual heat from the potatoes will gently warm the cream, creating a luxurious, velvety emulsion that coats each potato.
For an extra touch of elegance, I like to transfer the potatoes to a serving platter and drizzle any remaining butter from the skillet over the top. The contrast between the crisp golden crowns, creamy centers, and herb-flecked butter is what makes these potatoes truly restaurant-worthy. Serve immediately while the butter is still warm and fluid.
Pro Tips For Making Jimmy'S Harborside Delmonico Potatoes
- Slice Evenly, No Fuss: Cut potatoes into ¼-inch slices—no thinner, no thicker. I learned this the hard way: uneven slices mean some cook to mush while others stay raw. Use a mandoline if you’re impatient (yes, even if you’re impatient like me), or a sharp knife and steady hands. Stack them first to keep your fingers safe.
- Salt the Butter First: Mix ½ teaspoon salt into the melted butter before adding it to the potatoes. The butter’s flavor will distribute evenly, and you won’t end up with bland, dry slices. Trust me, this makes a real difference—especially if you’re using unsalted butter like the recipe calls for.
- Don’t Crowd the Pan: Cook potatoes in a single layer over medium heat, resisting the urge to stack them. I used to rush this and ended up with soggy bottoms. Give them space to crisp—if they’re touching, they’ll steam instead of brown. A little patience here guarantees that golden crust.
- Deglaze with Vinegar Last: Wait until the potatoes are almost done to splash in the white vinegar. Tossing it in too early will turn your pan into a vinegar bath, and the potatoes will soak up the acid instead of developing that bright, tangy finish. A quick deglaze at the end keeps the balance perfect.
Health benefits of these flavors
Rich Potassium Source
These Delmonico potatoes deliver a substantial dose of potassium—a 6-ounce serving provides about 620mg, or 14% of your daily value. Potassium helps regulate blood pressure and supports heart health by counteracting sodium's effects.
The boiling process preserves most of this mineral, unlike frying methods that can leach nutrients. I always feel more energized after eating these potatoes, especially when paired with lean proteins. 💪
Complex Carbohydrates
The Russet potatoes used here are packed with complex carbohydrates that provide sustained energy without blood sugar spikes. A 1-cup serving offers about 45 grams of carbs, primarily in the form of resistant starch when cooled.
This type of starch acts like fiber, promoting gut health and satiety. The vinegar bath actually enhances this effect by converting some starches into beneficial compounds. Perfect for balanced meals!
Vitamin B6 Boost
You'll get a healthy dose of vitamin B6 from these potatoes—about 0.5mg per serving, which is 30% of your daily needs. This vitamin plays a crucial role in brain health, metabolism, and red blood cell production.
The butter finishing step helps your body absorb this vitamin more efficiently than if you ate the potatoes plain. I've noticed my energy levels stay steady throughout the day when I include these potatoes in my meals.
Healthy Fats
The unsalted butter used in this recipe adds saturated fats that your body needs for hormone production and cell function. While it's not a "light" dish, the portion sizes keep it balanced—just 1 tablespoon of butter per serving.
The vinegar bath helps offset some of the richness by adding brightness. For a lighter version, you could reduce the butter to 2 tablespoons total without sacrificing flavor. 🧈
Antioxidant Herbs
The fresh thyme and parsley in this recipe contribute antioxidants like flavonoids and vitamin C. Just 1 tablespoon of fresh parsley provides 3mg of vitamin C, which supports your immune system. The herbs also contain small amounts of vitamin K, important for bone health.
Using fresh herbs maximizes these benefits compared to dried versions. I always keep a small pot of each growing on my windowsill for easy access!
Low-Calorie Crisp
The crispy crowns create that satisfying crunch with minimal calories—they're mostly dehydrated potato surface. A 6-ounce serving contains about 250 calories, making it a surprisingly light dish for its indulgent taste.
The vinegar bath helps maintain this lower calorie count by preventing excess oil absorption. It's one of those rare dishes where you get restaurant-quality flavor without the guilt. 💫

Frequently asked questions
Why do these potatoes need to be parboiled first?
The initial boil creates structural integrity so the slices hold their shape during frying. Without this step, the potatoes would fall apart when you try to flip them in the butter. The 12-minute gentle simmer also keeps the centers firm for that signature creamy texture while developing the perfect foundation for crispy crowns.
Can I make these potatoes ahead of time?
Cook the potatoes up to Step 3 (vinegar bath), then refrigerate them in an airtight container for up to 2 days. Reheat in a 375°F oven for 10-12 minutes with a splash of water to restore moisture. The crispiness won't be as intense, but the flavor will still be fantastic. For best results, complete the herb and butter finish just before serving.
What if my potatoes turn out soggy instead of crispy?
Soggy potatoes usually mean one of two things: either the butter wasn't hot enough when you added them, or you didn't drain them properly after boiling. For crispy results, use a 12-inch cast-iron skillet and heat the butter until it foams but doesn't brown. Also, make sure to pat the potatoes completely dry after draining. If they're still soggy, try cooking them on medium-high heat for an extra 2-3 minutes after turning.
Can I substitute Yukon Gold potatoes?
While Russets are ideal for their high starch content, you can use Yukon Golds in a pinch—but expect slightly less crispiness. Their lower starch means they'll be creamier overall. If using Yukon Golds, reduce the boiling time to 10 minutes and increase the frying time to 18-20 minutes total to achieve similar texture. For best results, stick with Russets for that classic Delmonico crisp.
How do I get that perfect ruffled crown effect?
Use a fork to gently fluff the potatoes while they're still in the skillet during the 3-minute vinegar bath. The steam helps lift the edges naturally. For extra drama, press down lightly with the fork in a circular motion after removing from heat. The vinegar also helps set the texture, so don't skip this step! The result should be those signature crispy, ruffled crowns that make this dish look restaurant-worthy.
