Step-by-Step Instructions

Step 1: Prepare the Baking Dish

Preheat your oven to 425°F (220°C).

Grease an 8×8-inch baking dish with butter to prevent sticking.

Step 2: Sauté Aromatics

In a large saucepan, melt 2 tablespoons of butter over medium heat.

Add ½ minced white onion and cook until translucent, about 5 minutes.

Stir in 2 minced garlic cloves, 1½ teaspoons salt, and ½ teaspoon black pepper.

Cook for an additional 30 seconds until fragrant.

Step 3: Simmer Potatoes

Pour in ½ cup chicken stock and 1¼ cups heavy cream, stirring to combine.

Add 1½ pounds of peeled and thinly sliced russet potatoes to the mixture.

Bring to a gentle simmer (do not boil), cover, and cook for 15–20 minutes until potatoes are just tender.

Step 4: Assemble the Dish

Transfer the potato mixture into the prepared baking dish, spreading evenly.

Top with 2 cups shredded cheddar cheese, ¾ cup shredded provolone cheese, and ½ cup grated Parmesan cheese.

Step 5: Bake

Place the dish in the preheated oven and bake uncovered for 10–15 minutes, or until the cheese is bubbly and golden brown.

Step 6: Garnish and Serve

Remove from the oven and let it rest for 5–10 minutes.

Garnish with chopped fresh parsley before serving.

Serving Suggestions

Main Courses: Perfect alongside grilled steaks, roasted chicken, or baked ham.

Vegetables: Complement with steamed green beans, roasted asparagus, or a fresh garden salad.

Beverages: Pair with a crisp white wine or a light-bodied red for a balanced meal.

Variations & Substitutions

Potatoes: Substitute russet potatoes with Yukon Gold for a creamier texture.

Cheeses: Experiment with Gruyère or Fontina for different flavor profiles.

Herbs: Incorporate fresh thyme or rosemary into the cream mixture for added aroma.

Vegetarian Option: Use vegetable stock instead of chicken stock.

Lighter Version: Replace heavy cream with half-and-half for a lighter sauce.

Storage & Leftovers

Refrigerate: Store leftovers in an airtight container in the refrigerator for up to 3 days.

Reheat: Warm in a 350°F (175°C) oven until heated through, or microwave individual portions.

Freeze: Not recommended, as the cream sauce may separate upon thawing.

FAQs

Can I prepare this dish ahead of time?
Yes, assemble the dish without baking, cover, and refrigerate. When ready to serve, bake as directed, adding a few extra minutes if needed.

What if I don’t have all three cheeses?
You can use just cheddar or a combination of any melty cheeses you have on hand.

How do I prevent the sauce from curdling?
Ensure you simmer the cream mixture gently and avoid boiling to maintain a smooth sauce.

Can I add other ingredients like bacon or herbs?
Absolutely! Cooked bacon bits or fresh herbs like thyme can enhance the flavor.

Is it necessary to peel the potatoes?
Peeling is recommended for a smoother texture, but you can leave the skins on for a more rustic dish.

Can I use milk instead of heavy cream?
Using milk will result in a thinner sauce; for best results, stick with heavy cream or half-and-half.

What type of baking dish works best?
An 8×8-inch glass or ceramic baking dish is ideal for even cooking and presentation.
