How to Make Simply Delicious Potato Side Dishes Delmonico Style
Preheat oven: Arrange a rack in the top third of the oven and heat it to 400°F. Generously coat a broiler-safe 9×13-inch baking dish with butter for easy release later.
Boil potatoes: In a large pot, combine the peeled, diced gold potatoes and 2 tablespoons of kosher salt. Add cold water to cover by about 1 inch. Bring to a boil over high heat; then, reduce to a simmer, cooking for 7 to 10 minutes until just tender when pierced with a fork. Drain well.
Sauté garlic: In a medium saucepan over medium heat, melt 1 tablespoon of unsalted butter. Add the minced garlic, stirring until fragrant and light golden-brown, about 2 minutes.
Create the sauce: Pour in 2 1/2 cups of heavy cream, 2 teaspoons of Dijon mustard, the remaining 1 teaspoon of kosher salt, 1 teaspoon black pepper, and 1/4 teaspoon freshly grated nutmeg. Cook while stirring occasionally until the mixture starts to simmer.
Melt cheese: Reduce the heat to low. Add 4 ounces of the sharp white cheddar cheese and 3 ounces of the Parmesan cheese, stirring until melted and smooth. Remove from heat.
Assemble gratin: Spread the drained potatoes evenly in the prepared baking dish. Pour the creamy sauce over them, ensuring even coverage. Top with the remaining 4 ounces of sharp white cheddar cheese and 1 ounce of Parmesan cheese.
Bake: Place in the oven and bake until the sauce is bubbling at the edges and the cheese begins to brown, about 20 to 25 minutes.
Broil: Switch the oven to broil on high for an additional 2 to 4 minutes until the top is golden-brown. Allow to cool for 10 minutes before serving. If desired, garnish with chopped fresh chives or parsley.
Optional: Sprinkling extra cheese on top before broiling adds a glorious stretch!

Expert Tips for Simply Delicious Potato Side Dishes
- Choose the Right Potatoes: Gold potatoes retain creaminess; avoid waxy varieties which can result in a mushy texture in your gratin.
- Don’t Overcook: Boil potatoes until just tender; overcooking can lead to mushiness in your simply delicious potato side dish.
- Gradual Heating: When adding the cream mixture, ensure you slowly heat it to avoid curdling; stir continuously for creamy perfection.
- Layer for Flavor: For deeper taste, layer your potatoes with more cheese in between; this enhances the cheesy goodness throughout.
- Watch the Broil: Be vigilant while broiling; a minute too long can turn your golden crust to charred bits.
- Garnish with Freshness: Always opt for fresh chives or parsley as garnish; it elevates your dish visually and quickly enhances flavor!

Simply Delicious Potato Side Dishes Delmonico Style Recipe FAQs
How do I choose the best potatoes for this recipe?
Absolutely! For making this simply delicious potato side dish Delmonico style, I recommend using medium to large gold potatoes. They are perfect because they break down slightly while cooking, which creates a creamy texture. Look for firm potatoes without dark spots or blemishes, as these signs can indicate they are past their prime and might affect the quality of your gratin.
How long can I store leftover potato gratin in the fridge?
Very! Your leftover potato gratin can be stored in an airtight container in the refrigerator for up to 3 days. Just make sure it has cooled completely before sealing it up to preserve that fresh taste and avoid excess moisture, which can lead to sogginess.
Can I freeze potato gratin, and if so, how?
The more the merrier! You can definitely freeze your potato gratin. First, allow it to cool completely. Then, wrap individual portions tightly in plastic wrap followed by aluminum foil to prevent freezer burn. It can be frozen for up to 2 months. When you’re ready to enjoy it again, simply thaw it overnight in the fridge, then reheat in the oven at 350°F for about 20 minutes or until it’s warmed through—a delightful treat!
What if my potato gratin is too runny?
If your gratin is too runny, it could be due to a few factors, such as undercooking the potatoes or not using enough cheese. To remedy this, you can return it to the oven and let it bake for an additional 5-10 minutes to reduce the liquid. If you’re still concerned, you can thicken the cream sauce with a cornstarch slurry: mix 1 tablespoon of cornstarch with 2 tablespoons of cold water until smooth, then stir it into the sauce and heat until thickened.
Is this potato gratin recipe suitable for people with dietary restrictions?
Absolutely! This gratin is rich and indulgent, but if you have dietary considerations, you can make some adjustments. For dairy-free options, you could use cashew cream or coconut cream in place of heavy cream and choose dairy-free cheeses. Always check ingredient labels to ensure they meet your specific dietary needs. Just be aware, if serving to pets, ingredients like garlic and cheese might not be suitable for them!
How do I reheat leftover potato gratin without it getting rubbery?
Great question! To reheat your leftovers without sacrificing texture, avoid using a microwave. Instead, preheat the oven to 350°F, place the gratin in an oven-safe dish, and cover it with foil to preserve moisture. Heat for about 20 minutes or until warmed through. This method helps maintain the creamy texture and delicious flavor of your simply delicious potato side dish Delmonico style!
