Step-by-Step Instructions

1. Preheat the oven

Preheat your oven to 375°F (190°C).

Lightly grease a 9×13-inch baking dish with butter or cooking spray.

This prevents the potatoes from sticking during baking.

2. Prepare the potatoes

Wash and peel the potatoes if desired.

Slice them thinly using a sharp knife or mandoline.

Thin slices cook faster and absorb the sauce better.

3. Make the cheese sauce

In a medium saucepan, melt the butter over medium heat.

Add the minced garlic and cook for about 30 seconds until fragrant.

Stir in the flour and cook for 1 minute, stirring constantly.

Slowly pour in the milk while whisking to avoid lumps.

Continue cooking until the sauce thickens slightly.

4. Add cheese and seasoning

Add half of the cheddar cheese and half of the mozzarella cheese to the sauce.

Stir until the cheese melts and the sauce becomes smooth.

Add salt, black pepper, paprika, thyme, and onion powder if using.

Mix well.

Small tip: keeping the heat medium-low prevents the cheese from separating.

5. Layer the potatoes

Place half of the sliced potatoes in the bottom of the baking dish.

Pour some of the cheese sauce over the potatoes.

Spread it evenly.

Add the remaining potatoes on top.

Pour the rest of the sauce over the final layer.

6. Add the topping

Sprinkle the remaining cheddar and mozzarella cheese over the top.

Add Parmesan cheese if using.

This will create a golden and slightly crispy top.

7. Bake the dish

Cover the baking dish with aluminum foil.

Bake for 40 minutes.

Then remove the foil and bake for another 15–20 minutes until the top is golden and bubbly.

8. Let it rest

Remove the dish from the oven and allow it to rest for about 10 minutes.

This helps the sauce thicken and makes serving easier.
