👩‍🍳 Instructions

1. Parboil the Potatoes

Place diced potatoes in a large pot of salted water. Bring to a boil and cook for 6–8 minutes until just tender but not falling apart. Drain and set aside.

2. Make the Cheese Sauce

In a medium saucepan, melt 2 tablespoons of butter over medium heat. Whisk in the flour and cook for 1 minute to make a roux. Gradually whisk in the milk and cream until smooth. Cook, stirring frequently, until thickened — about 5–7 minutes.

3. Season and Add Cheese

Stir in Dijon mustard (if using), garlic powder, onion powder, salt, and pepper. Remove from heat and mix in the shredded cheddar cheese until melted and smooth.

4. Assemble the Dish

Preheat oven to 375°F (190°C). Lightly butter or spray a 9x13-inch baking dish. Spread the parboiled potatoes evenly in the dish. Pour the cheese sauce over the potatoes and gently stir to coat.

5. Add Topping

In a small bowl, combine Parmesan, breadcrumbs, and 1 tablespoon melted butter. Sprinkle the topping evenly over the potatoes.

6. Bake

Bake uncovered for 25–30 minutes, or until the top is golden brown and bubbling.

7. Rest and Serve

Let rest for 5–10 minutes before serving. Garnish with chopped parsley if desired.

✨ My Personal Touch

Delmonico Potatoes are a nostalgic dish for me — I grew up enjoying them at Sunday dinners and always loved that cheesy crust! This version strikes the perfect balance of creaminess and crunch, and I often pair it with grilled chicken or even a simple salad for a decadent midweek meal. It’s one of those sides that quietly steals the show.
