Ingredients You’ll Need

For the Potato Layers

2 pounds Yukon Gold potatoes – Thinly sliced; their waxy texture holds shape while releasing enough starch to thicken the sauce naturally.
1 medium onion – Finely chopped to distribute sweetness evenly throughout the dish.

For the Cream Sauce

2 cups heavy cream – Forms the base of the sauce, providing richness and moisture during baking.
2 cloves garlic – Minced; adds aromatic depth without overpowering the potatoes.
1 teaspoon salt – Enhances overall flavor and balances the dairy.
½ teaspoon black pepper – Provides gentle warmth and seasoning.
½ teaspoon paprika – Adds subtle smokiness and color.
¼ teaspoon cayenne pepper (optional) – Introduces mild heat for contrast.

For the Cheese & Finish

1 cup shredded sharp cheddar cheese – Contributes bold flavor and meltability.
1 cup shredded Gruyère cheese – Adds nutty complexity and smooth texture.
2 tablespoons fresh parsley – Chopped; used as a fresh, herbaceous garnish.

Step-by-Step Instructions

Preheat and Prepare the Potatoes

Preheat the oven to 375°F (190°C). Wash, peel, and slice the potatoes into uniform ⅛-inch slices using a mandoline or sharp knife for even cooking.

Sauté the Aromatics

In a medium saucepan over medium heat, melt 2 tablespoons of butter. Add the chopped onion and cook for about 5 minutes until translucent, then add the garlic and cook for 1 minute until fragrant.

Build the Cream Sauce

Pour in the heavy cream and stir in salt, black pepper, paprika, and cayenne if using. Bring the mixture to a gentle simmer, then remove from heat to prevent scorching.

Layer the Components

Grease a 9×13-inch baking dish. Arrange half of the potatoes evenly, pour over half the cream sauce, and sprinkle with half of both cheeses. Repeat with remaining potatoes, sauce, and cheese.

Bake Covered

Cover the dish tightly with aluminum foil and bake for 45 minutes, allowing the potatoes to steam and soften fully.

Brown and Finish

Remove the foil and continue baking for 15–20 minutes until the top is golden and bubbling and a fork slides easily into the potatoes.

Rest and Garnish

Let the dish rest for 5–10 minutes before serving, then sprinkle with chopped parsley to finish.

Recipe Notes & Tips

Uniform Slicing Matters – Even potato thickness ensures consistent cooking and prevents underdone centers.
Avoid High Heat on Cream – Gentle simmering prevents separation and graininess in the sauce.
Cheese Placement Is Key – Layering cheese throughout prevents dry pockets and improves cohesion.
Foil Seal Technique – Tightly sealing the foil traps steam, critical for tender potatoes.
Resting Time Improves Structure – Cooling slightly allows the sauce to set for cleaner slices.
Season Gradually – Taste the cream sauce before layering to adjust salt and spice levels.

Storage & Serving Tips

Refrigeration: Store leftovers covered for up to 3 days.
Reheating: Warm gently in the oven at 325°F to preserve texture.
Freezing: Not recommended, as cream-based sauces may separate.
Serving Temperature: Best served warm, not piping hot, for optimal flavor.

Creative Variations to Try

Smoked Cheese Blend – Replace part of the cheddar with smoked Gouda for deeper flavor.
Herb-Infused Cream – Add thyme or rosemary to the cream while simmering.
Lighter Version – Substitute half-and-half for part of the cream and reduce cheese slightly.
Add Protein – Thin slices of ham or cooked bacon can be layered in for a heartier dish.

Troubleshooting Common Issues

Potatoes Are Still Firm – Cover again and bake an additional 10–15 minutes.
Sauce Is Too Thin – Let the dish rest longer; it thickens as it cools.
Top Is Browning Too Fast – Tent loosely with foil and continue baking.
Greasy Texture – Reduce cheese slightly or use freshly grated cheese instead of pre-shredded.

Why This Recipe Works

This recipe succeeds because it relies on classic scalloped potato principles: thin slicing for even heat transfer, starch release from Yukon Gold potatoes to naturally thicken the sauce, and controlled dairy heating to prevent separation. Layering cheese ensures even distribution and proper melt, while the two-stage baking method balances tenderness and browning. At roughly 400 calories per serving, it’s indulgent yet reasonable for a special side dish.

Final Thoughts

Blue Bayou Scalloped Potatoes deliver everything expected from a comfort-food classic: creamy texture, balanced seasoning, and reliable results. While rich by design, lighter adjustments are easily achievable without sacrificing structure or flavor. Whether served at a holiday table or alongside a simple roast, this dish remains a timeless, satisfying addition to any meal.
