Ingredients for jimmy's harborside delmonico potatoes

Six ingredients transform into restaurant-quality Delmonico potatoes with crispy crowns and velvety centers.

The potatoes are the foundation—Russet potatoes with their high starch content are non-negotiable for that signature crispy exterior. Look for firm, blemish-free potatoes at specialty grocers like Whole Foods or Harris Teeter, where they're typically sold in pre-washed bags. Slice them uniformly at 1/8-inch thickness using a mandoline for precision (the OXO Good Grips model is my go-to). Thin slices ensure even cooking and that perfect golden crust. The secret to restaurant-quality results lies in the cold chain—keep the sliced potatoes in ice water until ready to layer, which prevents browning and maintains texture.

No fresh parsley? Dried parsley at one-quarter the amount works in a pinch, though it lacks the vibrant freshness. Substituting Gruyère? Parmesan or sharp cheddar will alter the flavor profile but still deliver that creamy, melty finish. The heavy cream must be full-fat—half-and-half or light cream won't achieve the same luxurious texture. For the herb blend, fresh chives and garlic are essential; dried versions simply can't replicate the aromatic depth. If you're short on time, pre-minced garlic from a jar is acceptable, though freshly minced garlic adds an extra layer of complexity. The olive oil should be extra-virgin—its fruity notes complement the earthy potatoes without overpowering them.

Layer the potatoes in a 9x13-inch baking dish (the Le Creuset Stoneware dish is ideal for even heat distribution) and refrigerate uncovered for at least 30 minutes before baking. This chilling step ensures the potatoes crisp properly. Once baked, transfer to a wire rack for 10 minutes to prevent sogginess—this is critical for maintaining that golden crust. The dish reheats beautifully; cover with foil and warm in a 350°F oven for 15 minutes. For make-ahead convenience, assemble the dish up to 24 hours in advance, cover tightly, and refrigerate. The flavors deepen overnight, making it perfect for holiday gatherings where prep happens days ahead.

Step-by-step instructions for herb-infused Delmonico potatoes

Here's the precise method to achieve Jimmy's signature texture—crispy golden crowns with velvety interiors.

Using a mandoline or sharp knife, slice the 3 lbs russet potatoes into 1/8-inch rounds. I like to work in batches to maintain even thickness. Immediately place the slices in a cold water bath to prevent browning while you prepare the herb mixture.

Drain the potatoes and pat them completely dry with clean kitchen towels—moisture is the enemy of crispy exteriors. In a small bowl, combine the 2 tbsp all-purpose flour, 1.5 tsp diamond crystal kosher salt, 0.5 tsp freshly ground black pepper, 0.25 cup finely chopped fresh parsley, 0.25 cup thinly sliced fresh chives, and 4 minced garlic cloves. Toss the potato slices in this seasoned flour mixture until evenly coated.

Preheat your oven to 400°F and arrange two oven racks—one in the upper third and one in the lower third of the oven. This creates even heat circulation for perfect browning. Grease two 9x13-inch baking dishes with 2 tbsp extra-virgin olive oil to prevent sticking.

Begin layering the potatoes in the dishes, slightly overlapping each slice. Drizzle 1 tbsp extra-virgin olive oil between each layer, then dot with 2 tbsp cold cubed unsalted butter. Repeat until all potatoes are layered, finishing with butter on top. Bake for 45 minutes, then rotate the pans front to back and bake for another 15 minutes until the edges are deep golden brown and crispy.

While the potatoes bake, heat the 1.5 cups heavy whipping cream in a saucepan over medium-low heat until it just begins to simmer. Remove from heat and stir in the 1 cup shredded gruyère cheese until fully melted and smooth. Season with an additional 0.5 tsp diamond crystal kosher salt and 0.25 tsp freshly ground black pepper to taste. Keep warm until ready to use.

Remove the baked potatoes from the oven and immediately pour the creamy gruyère mixture evenly over each pan. Return to the oven for 5-7 minutes until the cheese has melted and the tops are bubbly and golden. Watch closely—the cheese should be fully melted but not browned.

Let the potatoes rest for 10 minutes before serving. This resting period allows the layers to set and the flavors to meld. The result should be crispy potato crowns with creamy, cheesy interiors that hold together perfectly. Garnish with additional fresh chives if desired, and serve immediately while still warm.

Pro cooking tips for this recipe

Layering Precision

Uniform layering is the foundation of perfect Delmonico potatoes. Use a mandoline slicer to achieve 1/8-inch thick slices—any thicker, and the centers won’t stay creamy. Arrange slices in concentric circles, slightly overlapping each piece, to maximize surface area for crisping.

I like to work in three layers per pan, with each layer getting a light drizzle of olive oil and cold butter cubes—this prevents sticking and promotes even browning. 🌡️

Butter Temperature Matters

Cold butter is non-negotiable for achieving that signature crispy exterior. Use room-temperature butter (softened but not melted) when layering, and finish with cold cubed butter on top. The cold butter melts during baking, creating steam that keeps the potatoes moist while the exterior crisps.

I recommend Plugrá European-style butter—its higher fat content (82%) delivers superior texture. Never skip this step; it’s what separates homemade from restaurant-quality results.

Herb Infusion Technique

Fresh herbs make all the difference in flavor. For maximum aroma, pulse the parsley and chives in a food processor for 3 seconds before mixing with flour—this releases essential oils that infuse the potatoes. Add the minced garlic last to preserve its freshness.

I also like to toast the herbs lightly in a dry pan for 30 seconds before mixing, which enhances their flavor profile. This technique ensures every bite is packed with herbal brightness. 🌿

Oven Rack Strategy

Place baking dishes on upper and lower oven racks simultaneously to create a convection effect. This ensures even heat distribution and prevents the top layer from browning too quickly. Rotate the pans front-to-back halfway through baking to eliminate hot spots.

If your oven runs hot, reduce the temperature to 375°F—this subtle adjustment prevents burning while maintaining crispiness. A thermometer probe in one pan helps monitor internal temperature accurately.

Cheese Melting Mastery

Gruyère’s lower melting point makes it ideal for Delmonico potatoes. Heat the cream to just simmering (not boiling) to avoid breaking the fat molecules, which would make the sauce grainy. Stir in the cheese off the heat to prevent clumping.

For extra richness, add 1 tbsp cold heavy cream at the end—this creates a silky finish. Watch the cheese closely during the final 5-7 minutes in the oven; it should be fully melted but not browned. 🧀

Resting for Perfection

Never skip the 10-minute rest after baking. This allows the layers to set and the flavors to meld. Transfer the dish to a wire rack (not the counter) to prevent sogginess from residual heat. For serving, use a spatula to lift the potatoes gently—this preserves the crispy crowns.

If reheating, cover loosely with foil and warm at 350°F for 10-15 minutes to restore texture without overcooking. The result? A dish that looks and tastes like it came straight from Jimmy’s Harborside.
