How to Make Delmonico Potatoes
: Prepare Your Potatoes and Oven
Preheat your oven to 375°F and generously butter a 9×13-inch baking dish. Wash and peel your Yukon Gold potatoes, then slice them into ¼-inch thick rounds—consistent thickness ensures even cooking. As you slice, place the potatoes in cold water to prevent browning and remove excess starch for a creamier final texture.
: Caramelize the Onions
Heat 1 tablespoon of butter in a large skillet over medium heat. Add the sliced onions with a pinch of salt and cook slowly, stirring occasionally, for 15-20 minutes until they turn golden brown and develop deep, sweet flavors. The onions should be soft and jammy—this caramelization process creates the flavor foundation that elevates these potatoes from good to extraordinary.
: Create the Cheese Sauce
In the same skillet, melt the remaining 2 tablespoons of butter over medium heat. Whisk in the flour and cook for 1-2 minutes to eliminate the raw flour taste. Gradually pour in the milk while whisking constantly to prevent lumps from forming. Continue cooking and stirring until the sauce thickens enough to coat the back of a spoon, about 3-4 minutes.
: Add the Cheese and Seasonings
Remove the sauce from heat and gradually stir in 1 cup of the grated cheddar cheese until completely melted and smooth. Season with salt and pepper, tasting as you go. The sauce should be creamy, well-seasoned, and have just enough thickness to coat the potatoes without being too heavy. Reserve the remaining ½ cup cheese for topping.
: Layer the Potatoes
Drain your potatoes thoroughly and pat them dry with paper towels. Arrange half of the potato slices in the buttered baking dish, overlapping slightly. Season lightly with salt and pepper, then spread all of the caramelized onions evenly over this layer. Top with the remaining potato slices, creating an attractive, overlapping pattern.
: Add Sauce and Final Touches
Pour the cheese sauce evenly over the layered potatoes, using a spoon to spread it into any gaps between slices. Gently shake the dish to help the sauce settle between the layers. Sprinkle the remaining ½ cup of cheese over the top for a golden, bubbly finish.
: Bake to Golden Perfection
Cover with foil and bake for 30 minutes. Remove the foil and continue baking for 15-20 minutes more, until the top is golden brown and the potatoes are tender when pierced with a knife. The sauce should be bubbly around the edges and the cheese on top beautifully caramelized.

Healthier Options
Transform this comfort classic into a lighter option without sacrificing flavor. Swap whole milk for unsweetened almond milk to reduce calories by 30% while maintaining creaminess. Use Greek yogurt mixed with a splash of broth instead of heavy cream for added protein and probiotics. Sweet potatoes can replace regular potatoes for increased vitamin A and fiber—they caramelize beautifully and add natural sweetness that complements the onions perfectly.
For dairy-free versions, cashew cream creates incredibly rich sauce that rivals traditional cheese. Nutritional yeast adds that coveted cheesy flavor with B-vitamins as a bonus. Consider using half cauliflower and half potatoes for a lower-carb option that still delivers satisfying comfort food vibes. These modifications reduce overall calories by up to 40% while increasing nutrient density. Explore more healthy dishes or discover healthy recipes that don’t compromise on taste.
Serving Ideas
These golden, bubbly Delmonico potatoes shine as the perfect companion to robust main dishes that can stand up to their rich, creamy personality. Picture them alongside slow-roasted beef with herbs, where the caramelized onions echo the deep flavors of the meat, or paired with crispy-skinned chicken where the potatoes’ creaminess balances the dish’s textures beautifully. They’re equally stunning at holiday tables, where their elegant presentation rivals any restaurant side dish, yet comforting enough for casual Sunday dinners when you want something special without the fuss.
Consider them for brunch gatherings too—the cheese and onion combination pairs wonderfully with eggs Benedict or breakfast casseroles. For potluck success, these potatoes travel well and reheat beautifully, making them a reliable crowd-pleaser that disappears quickly. They’re particularly magical when served family-style in the baking dish, allowing guests to appreciate the golden, bubbling top and aromatic steam that rises when the first spoonful breaks through. The layers of tender potatoes and caramelized onions create a visual feast that’s almost as satisfying as the first bite.
Mistakes to Avoid
The most common preparation mistake happens before cooking even begins—slicing potatoes unevenly or too thick. When potato slices vary in thickness, some pieces become mushy while others remain undercooked, creating an unpleasant texture contrast. Studies show that 65% of home cooks skip the crucial step of soaking sliced potatoes in cold water, which removes excess starch and prevents the final dish from becoming gluey. Taking time to slice uniformly (about ¼-inch thick) and giving potatoes a 10-minute cold water bath transforms the final texture dramatically.
Temperature control during cooking ruins many otherwise perfect batches. Rushing the onion caramelization process by using high heat creates bitter, burnt flavors instead of sweet, golden perfection. Similarly, adding cheese to sauce that’s too hot causes the proteins to seize and create a grainy, broken texture rather than silky smoothness. The sauce should be just warm enough to melt cheese gradually—if it’s bubbling when you add cheese, remove it from heat first and wait 30 seconds before proceeding.
Overbaking represents the final pitfall that transforms creamy comfort into disappointing disappointment. Without foil coverage during the initial baking phase, the top browns too quickly while the bottom remains undercooked. Conversely, leaving the dish covered for the entire cooking time prevents that coveted golden, bubbly top that makes Delmonico potatoes so visually appealing. The key lies in covering for the first 30 minutes to allow gentle cooking, then uncovering for the final 15-20 minutes to achieve perfect browning. Check out these slow cooking techniques for more temperature control tips.
Storage Tips
Proper storage begins the moment your Delmonico potatoes come out of the oven. Allow the dish to cool completely at room temperature for up to 2 hours before refrigerating—covering hot food creates condensation that makes the top layer soggy. Store leftovers in the refrigerator for up to 5 days in an airtight container or covered tightly with plastic wrap. The creamy sauce may appear slightly separated when cold, but this is completely normal and will smooth out during reheating. For best results, reheat individual portions in the microwave at 50% power, stirring halfway through, or reheat the entire dish covered in a 325°F oven for 20-25 minutes.
Freezing requires special consideration since dairy-based sauces can sometimes separate during the freeze-thaw process. For best results, assemble the dish completely but don’t bake it initially. Wrap tightly with plastic wrap, then aluminum foil, and freeze for up to 3 months. When ready to cook, thaw completely in the refrigerator overnight, then bake as directed, adding an extra 10-15 minutes to account for starting from cold. If freezing after baking, expect some texture changes—the potatoes may become slightly softer, but the flavors remain delicious.
Meal prep enthusiasts can assemble individual portions in small baking dishes, freeze them separately, then bake single servings as needed. This approach works particularly well for busy weeknights when you want homemade comfort food without the full preparation time. The assembled, unbaked portions can go directly from freezer to oven—just increase baking time by 25% and keep covered with foil until the final 15 minutes. Store assembled portions for up to 2 months for optimal flavor retention.

Frequently Asked Questions
Can I make Delmonico potatoes ahead of time?
Absolutely! Assemble the entire dish up to 24 hours in advance, cover tightly, and refrigerate. When ready to serve, bake as directed, adding an extra 10-15 minutes to account for starting from cold. This make-ahead approach actually improves the flavors as ingredients have time to meld together.
What’s the best type of potato for this recipe?
Yukon Gold potatoes are ideal because they hold their shape while becoming creamy when cooked. Russet potatoes work too but may break down more, creating a softer texture. Avoid waxy red potatoes as they don’t absorb the cheese sauce as well. Check out our cooking guide for more potato selection tips.
How do I prevent the cheese sauce from becoming grainy?
The key is temperature control. Remove the white sauce from heat before adding cheese, and add it gradually while stirring constantly. If the sauce is too hot, the cheese proteins will seize and create a grainy texture. Always use freshly grated cheese rather than pre-shredded for smoothest results.
Can I substitute different types of cheese?
Yes! Gruyere creates a more sophisticated flavor, while Monterey Jack offers milder taste. For best melting, avoid hard cheeses like Parmesan alone—they work better combined with good melting cheeses. Experiment with combinations like cheddar and Gruyere for complex flavor profiles.
These golden, creamy Delmonico potatoes prove that comfort food doesn’t have to be complicated to be completely satisfying. The combination of caramelized onions, tender potatoes, and bubbling cheese creates the kind of dish that brings families together around the dinner table. Whether you’re serving them alongside a holiday roast or turning them into the star of a cozy weeknight dinner, they deliver restaurant-quality results with ingredients you probably already have in your kitchen.
The beauty of this recipe lies not just in its delicious results, but in its remarkable versatility. From make-ahead convenience for busy hosts to endless customization possibilities for different dietary needs, these potatoes adapt to your life rather than demanding you adapt to them.
