Ingredients

2 tablespoons unsalted butter
2 large yellow onions, thinly sliced
1 teaspoon granulated sugar (optional, for faster caramelizing)
1 tablespoon olive oil (optional, if onions look dry)
2 cups heavy cream
1 cup finely grated Parmesan cheese, plus 2 tablespoons for topping
1 1/2 teaspoons kosher salt, divided
1 teaspoon freshly ground black pepper
2 teaspoons fresh thyme leaves, chopped (or 1 teaspoon dried thyme)
3 pounds russet or Yukon Gold potatoes, peeled (if desired) and thinly sliced
1 tablespoon unsalted butter or cooking spray, for greasing the glass casserole dish

Instructions

Step 1: Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch glass casserole dish with 1 tablespoon butter or cooking spray. Set aside.
Step 2: Caramelize the onions by melting 2 tablespoons butter in a large skillet over medium heat. Add the sliced onions and 1/2 teaspoon salt. Cook, stirring occasionally, for 20–25 minutes, lowering heat if they brown too quickly. If dry or starting to scorch, add 1 tablespoon olive oil and a splash of water. Optionally sprinkle 1 teaspoon sugar to speed caramelizing. Cook until onions are soft, golden, and fragrant. Remove from heat and let cool slightly.
Step 3: Whisk together the heavy cream, 1 cup grated Parmesan, remaining 1 teaspoon salt, black pepper, and thyme in a medium bowl or large measuring cup. Stir in the warm caramelized onions until combined to create your creamy pour-over mixture.
Step 4: Peel the potatoes if desired and slice into thin, even rounds about 1/8-inch thick using a sharp knife or mandoline.
Step 5: Arrange the sliced potatoes evenly in the greased casserole dish, spreading them out to avoid clumps and allow the cream to reach all slices.
Step 6: Give the creamy mixture a quick stir, then slowly pour it evenly over the potatoes, distributing onions and herbs carefully. Gently shake the dish or use a spoon to help the cream seep between the slices.
Step 7: Sprinkle the remaining 2 tablespoons grated Parmesan over the top. Cover the dish tightly with foil to steam and soften the potatoes.
Step 8: Bake covered on the middle rack for 45–55 minutes, until potatoes are fork-tender.
Step 9: Remove the foil and bake uncovered for another 15–20 minutes until the top is bubbly, golden, and edges are crisp in spots.
Step 10: Let rest for at least 10 minutes so the sauce thickens slightly. Serve warm for a satisfyingly creamy, cozy meal.

Tips & Variations

Use Yukon Gold potatoes for a creamier texture or russets for a fluffier bite.
Adding a pinch of nutmeg to the cream mixture enhances the flavor’s warmth.
Fresh thyme is preferred, but dried thyme works well if fresh is unavailable.
For a lighter option, substitute half-and-half for heavy cream, but the dish will be less rich.
Try adding cooked bacon or sautéed mushrooms between layers for extra savoriness.

Storage

Store leftover baked potatoes in an airtight container in the refrigerator for up to 3 days. To reheat, cover with foil and warm in a 350°F (175°C) oven until heated through, about 15-20 minutes, to preserve creaminess and texture. Avoid microwaving to keep the top crisp.

FAQs

Can I prepare this dish ahead of time?

Yes, you can assemble the dish a few hours ahead, cover it, and refrigerate before baking. Just add extra baking time if baking directly from cold.

Why should the potatoes be sliced thin?

Thin slices ensure even cooking and allow the creamy pour-over to soak into every layer, resulting in tender, flavorful potatoes.

Ingredients

Scale

For the Potatoes and Dish

3 pounds russet or Yukon Gold potatoes, peeled (optional) and thinly sliced (about 1/8-inch thick)
1 tablespoon unsalted butter or cooking spray, for greasing the casserole dish

For the Caramelized Onions

2 tablespoons unsalted butter
2 large yellow onions, thinly sliced
1 teaspoon granulated sugar (optional, for faster caramelizing)
1 tablespoon olive oil (optional, if onions look dry)
1/2 teaspoon kosher salt

For the Creamy Pour-Over Mixture

2 cups heavy cream
1 cup finely grated Parmesan cheese, plus 2 tablespoons for topping
1 teaspoon kosher salt
1 teaspoon freshly ground black pepper
2 teaspoons fresh thyme leaves, chopped (or 1 teaspoon dried thyme)

Instructions

Preheat and Prepare Dish: Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch glass casserole dish with 1 tablespoon butter or cooking spray and set aside.
Caramelize the Onions: In a large skillet over medium heat, melt 2 tablespoons butter. Add the sliced onions and 1/2 teaspoon salt. Cook, stirring occasionally, for 20–25 minutes until soft and golden brown. If onions dry out or scorch, add 1 tablespoon olive oil and a splash of water. Optionally sprinkle 1 teaspoon sugar to speed caramelizing. Remove from heat and let cool slightly.
Make Creamy Pour-Over: In a medium bowl or large measuring cup with a spout, whisk together 2 cups heavy cream, 1 cup grated Parmesan, 1 teaspoon salt, black pepper, and chopped thyme. Stir in the warm caramelized onions until thoroughly combined.
Prepare Potatoes: Peel potatoes if desired and slice into thin rounds about 1/8-inch thick, using a sharp knife or mandoline. Try for uniform slices to ensure even cooking.
Layer Potatoes: Arrange the sliced potatoes evenly in the greased casserole dish in an even layer or two, making sure there are no large clumps so the cream mixture can permeate the slices.
Pour Cream Mixture: Stir the creamy pour-over again briefly and pour it evenly over the raw potatoes, distributing the onions and herbs evenly. Gently shake the dish or use a spoon to nudge potatoes so the cream seeps between the slices.
Top and Cover: Sprinkle the remaining 2 tablespoons grated Parmesan over the top. Cover the dish tightly with foil to allow the potatoes to steam and soften without drying.
Bake Until Tender: Place the covered casserole dish in the preheated oven’s middle rack. Bake for 45–55 minutes until potatoes are fork-tender.
Brown the Top: Remove foil and continue baking for another 15–20 minutes until the top is bubbly, lightly golden, with browned and crisp edges.
Rest and Serve: Let the baked potatoes rest for at least 10 minutes to thicken the sauce before spooning onto plates and serving warm.

Notes

Peeling the potatoes is optional; leaving skins adds texture and nutrients.
Use a mandoline for uniformly thin potato slices to ensure even cooking.
Caramelizing onions slowly enhances their sweetness and depth of flavor.
Covering the dish while baking helps steam the potatoes, making them tender.
Resting the casserole after baking allows the sauce to thicken for better serving consistency.
This dish pairs well with roasted meats or a fresh green salad for a complete meal.
