For the Cheese Sauce
- 2 tablespoons unsalted butter (add an additional 2 tablespoons if skipping the bacon)
- 2 tablespoons all-purpose flour
- 2 cups whole milk
- 1/4 teaspoon sweet paprika
- 1 teaspoon dried thyme (chopped)
- 1 teaspoon dried rosemary (chopped)
- 12 ounces sharp cheddar cheese (shredded + more for topping as needed)

How to Make Cheesy Au Gratin Potatoes
Step 1: Preheat the Oven
Start by preheating your oven to 400°F. Slice off the tops of the bulb of garlic to expose the cloves. Drizzle with olive oil, wrap in foil, and bake for 30 to 35 minutes until soft and golden.
Step 2: Prepare Baking Dish
Once the garlic is finished baking, lower your oven temperature to 375°F (190°C). Grease a 9×13 inch baking dish with butter or oil.
Step 3: Cook the Bacon
In a large skillet over medium heat, cook the chopped bacon until crispy. Remove from heat, crumble it into pieces, and set aside. Reserve about 2–3 tablespoons of bacon fat in the skillet.
Step 4: Make the Roux
Add butter to the skillet with reserved bacon fat. Once melted, whisk in flour to create a roux. Cook for 1–2 minutes until golden brown.
Step 5: Thicken the Sauce
Gradually pour in whole milk while whisking constantly until the mixture thickens.
Step 6: Add Flavorings
Stir in roasted garlic (about 5–6 cloves), paprika, thyme, rosemary, salt, and pepper. Mix until well combined.
Step 7: Incorporate Cheese
Slowly add sharp cheddar cheese into the sauce while stirring until creamy.
Step 8: Layer Potatoes
Place thinly sliced potatoes in your greased baking dish. Pour cheese sauce evenly over potatoes and sprinkle crumbled bacon on top.
Step 9: Bake
Cover with aluminum foil and bake for 45 minutes. Uncover, add more sharp cheddar and white cheddar on top. Bake for an additional 15–20 minutes until potatoes are tender and top is golden brown.
