Pour this 1 creamy pour-over over potatoes into a glass casserole dish for a cozy winter supper that’s absurdly satisfying

These Creamy Pour-Over Baked Potatoes are a rich, comforting cold-weather dish that transforms simple potatoes into a velvety, restaurant-style side. The process starts by slowly cooking sliced yellow onions in butter until they become soft and deeply golden, adding a natural sweetness that balances the savory, salty notes of finely grated Parmesan. With the “pour-over” method, thin slices of Russet or Yukon Gold potatoes are bathed in a seasoned cream mixture, allowing thyme, onions, and cream to infuse every layer as it bakes into a bubbling, golden-topped gratin.

Creamy Pour-Over Baked Potatoes

Ingredients:

• Russet or Yukon Gold potatoes — 3 lbs
• Heavy cream — 2 cups
• Parmesan cheese (finely grated) — 1 cup + 2 tbsp
• Yellow onions (thinly sliced) — 2 large
• Unsalted butter (divided) — 3 tbsp
• Fresh thyme (chopped) — 2 tsp
• Kosher salt (divided) — 1½ tsp
• Black pepper — 1 tsp
• Granulated sugar (optional) — 1 tsp
• Olive oil (optional) — 1 tbsp

Step-by-Step Directions:

Step 1: Caramelize the Onions
Preheat the oven to 375°F. In a large skillet, melt 2 tablespoons of butter over medium heat. Add the sliced onions and ½ teaspoon of salt. Cook for 20–25 minutes, stirring occasionally.

Tip: If the onions begin to dry out or brown too quickly, add a tablespoon of olive oil along with a splash of water. Aim for soft, golden, and fragrant onions—reduce the heat as needed to prevent burning, as true caramelization develops slowly.

Step 2: Prepare the Cream Mixture
In a medium bowl or large measuring cup with a spout, whisk together the heavy cream, 1 cup of Parmesan, the remaining 1 teaspoon of salt, black pepper, and chopped thyme. Stir in the warm caramelized onions until evenly combined.

Step 3: Slice the Potatoes
Peel the potatoes if desired, or leave the skins on. Slice them into thin rounds about 1/8-inch thick.

Tip: A mandoline helps keep slices uniform, which ensures the potatoes cook evenly throughout.

Step 4: Layer and Pour
Arrange the potato slices in a greased 9×13-inch glass casserole dish. Give the cream mixture a final stir, then slowly pour it over the potatoes. Gently move the dish so the liquid settles between all the layers.

Step 5: Bake
Sprinkle the remaining 2 tablespoons of Parmesan over the top. Cover the dish tightly with foil and bake for 45–55 minutes, until the potatoes are tender. Remove the foil and continue baking for another 15–20 minutes until the top is golden and bubbling.

Step 6: Rest Before Serving
Let the dish rest for about 10 minutes after removing it from the oven.

Tip: During this resting time, the starch from the potatoes helps thicken the cream into a silky sauce that coats each slice instead of pooling at the bottom.
