Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with butter or non-stick cooking spray.
Peel the potatoes and slice them into thin rounds, about 1/8 inch thick. Use a sharp knife or mandoline slicer for uniform slices.
Thinly slice the yellow onion and mince the garlic cloves.
In a medium saucepan, melt the butter over medium heat. Add the sliced onion and garlic, and sauté until the onion is soft and translucent, about 5 minutes.
Reduce the heat to low and stir in the heavy cream. Add the salt, black pepper, dried thyme, and paprika. Cook for another 2-3 minutes, allowing the flavors to combine. Remove from heat.
Layer half of the potato slices evenly at the bottom of the prepared baking dish. Pour half of the cream mixture over the potatoes and sprinkle 3/4 cup of shredded cheddar cheese on top.
Add the remaining potato slices in an even layer, followed by the remaining cream mixture. Cover the dish with aluminum foil and bake for 30 minutes.
Remove the foil and sprinkle the remaining 3/4 cup of cheddar cheese over the potatoes. Return the dish to the oven, uncovered, and bake for an additional 10 minutes.
Sprinkle the crispy fried onions evenly over the top. Bake for another 5 minutes, or until the onions are golden and the dish is bubbling.
Remove from the oven and let the dish cool for 5-10 minutes. Garnish with chopped fresh parsley, if desired, before serving.
