Rich and Creamy Baked Potatoes with Pour-Over Sauce

This dish is ultimate winter comfort: thinly sliced potatoes layered in a glass casserole and smothered in a rich cream sauce with caramelized onions, Parmesan, and thyme. It bakes into a golden, bubbling masterpiece somewhere between scalloped potatoes and gratin—the kind of meal that fills your kitchen with warmth and coziness on a chilly evening.

Serve it with roasted chicken, meatloaf, or baked pork chops. A crisp green salad or steamed vegetables cut through the richness, while crusty bread and a side of applesauce or citrus slices round out a family-friendly feast.

Creamy Baked Potatoes 🥔✨

Ingredients:

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

Directions:

1. Preheat Oven
   Heat oven to 375°F (190°C). Grease a 9×13-inch glass casserole with butter or cooking spray.
2. Caramelize Onions
   Melt 2 tbsp butter in a skillet over medium heat. Add onions and ½ tsp salt. Cook 20–25 minutes, stirring occasionally, until golden and sweet. Add olive oil or a splash of water if needed. Optional: sprinkle sugar to speed caramelizing.
3. Make the Creamy Pour-Over
   In a bowl, whisk together cream, 1 cup Parmesan, remaining salt, pepper, and thyme. Stir in the warm caramelized onions.
4. Prepare Potatoes
   Peel if desired and slice into ⅛-inch rounds (a mandoline helps keep slices even).
5. Layer & Pour
   Arrange potato slices evenly in the casserole. Pour the creamy onion mixture over, nudging slices so the sauce seeps through.
6. Top & Cover
   Sprinkle remaining 2 tbsp Parmesan over the top and cover tightly with foil.
7. Bake Until Tender
   Bake 45–55 minutes until potatoes are fork-tender.
8. Brown the Top
   Remove foil and bake 15–20 minutes more until golden and bubbling.
9. Rest & Serve
   Let the casserole rest 10 minutes so the sauce thickens slightly. Serve warm and enjoy!

Tips:

• Even slices cook more evenly.
• Resting time ensures a creamy texture.
• Experiment with herbs like rosemary or paprika for extra flavor.
• Ideal for cozy winter dinners or holiday gatherings.
