Ingredients

• 4 medium (about 600g) Yukon Gold potatoes
• 1 large (about 200g) Yellow onion
• 2 tablespoons Olive oil
• 1 teaspoon Garlic powder
• 1 teaspoon Dried thyme
• 0.5 teaspoon Salt
• 0.5 teaspoon Black pepper
• 1 as needed Cooking spray
• 0.25 cup Panko bread crumbs
• 2 tablespoons Parmesan cheese (optional for added flavor)

Directions

Step 1

Preheat your oven to 400°F (200°C). Lightly grease a medium-sized casserole dish with cooking spray.

Step 2

Wash and peel the potatoes. Slice them into very thin rounds (about 1/8 inch thick) using a sharp knife or mandoline slicer.

Step 3

Peel the onion and slice it into thin rings. Separate the rings and set aside.

Step 4

Heat 1 tablespoon of olive oil in a skillet over medium heat. Add the onion rings and cook for 5-7 minutes, stirring occasionally, until they are slightly caramelized and softened. Set aside.

Step 5

In a small bowl, mix the garlic powder, dried thyme, salt, and black pepper together.

Step 6

Layer half of the sliced potatoes evenly across the bottom of the casserole dish. Sprinkle half of the seasoning mixture over the potatoes.

Step 7

Spread the caramelized onions over the seasoned potato layer.

Step 8

Arrange the remaining potato slices on top of the onions and sprinkle the rest of the seasoning mixture over the top.

Step 9

Drizzle the remaining 1 tablespoon of olive oil evenly over the top of the casserole.

Step 10

In a small bowl, mix the panko bread crumbs with 1 tablespoon of olive oil. If using Parmesan cheese, mix it in as well. Sprinkle the breadcrumb mixture evenly over the top of the casserole for a crunchy topping.

Step 11

Cover the casserole dish with foil and bake for 25 minutes in the preheated oven.

Step 12

Remove the foil and bake an additional 15 minutes, or until the potatoes are tender and the top is golden brown and crispy.

Step 13

Allow the casserole to cool for 5 minutes before serving. Enjoy this wholesome, low-calorie comfort dish!
