👩🍳 Instructions
1️⃣ Prep & Preheat
Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
Slice the potatoes evenly (about 1/8 inch thick) using a mandoline or sharp knife.
Prepare and measure all ingredients before starting.
2️⃣ Make the Sauce Base
Heat 1 tablespoon olive oil in a saucepan over medium heat.
Add diced onion with a pinch of salt and cook for 3 minutes until softened.
Add garlic and cook for another 2–3 minutes until fragrant.
Stir in the remaining olive oil, then sprinkle in flour. Cook for about 1 minute, stirring constantly to form a roux.
Gradually whisk in the milk and cook for 5–7 minutes until thickened.
3️⃣ Finish the Sauce
Remove from heat and stir in cheddar cheese until melted.
Add broth, garlic powder, cayenne pepper, and Greek yogurt. Mix until smooth and creamy.
Taste and adjust seasoning with salt and pepper.
4️⃣ Assemble & Bake
Spread about ½ cup of sauce on the bottom of the baking dish.
Layer the sliced potatoes evenly, slightly overlapping.
Pour the remaining sauce over the potatoes, making sure everything is well coated.
Cover with foil and bake for 30 minutes.
Remove, gently stir or redistribute sauce if needed, then bake covered for another 15 minutes until nearly tender.
5️⃣ Finish & Serve
Remove foil and sprinkle parmesan cheese on top.
Increase oven temperature to 450°F (230°C) and bake uncovered for 5 minutes until golden.
Garnish with fresh thyme and let rest for 5 minutes before serving.
