Equipment You Need
- Medium saucepan (2–3 qt) — for the roux and sauce.
- 9 × 13-inch baking dish — ceramic or glass works best for even heat and nice edges.

- Aluminum foil — to cover the casserole during the initial bake and trap steam.
- Instant-read thermometer — useful to check that the center reaches at least 165°F (74°C).
Step-by-Step Guide
This recipe takes roughly total, including prep and baking. Follow these steps for consistent, creamy results.
Prep & Sauce
Preheat oven and slice the potatoes. Set oven to 350°F (175°C) and place the rack in the center. Peel and slice potatoes about 1/8-inch thick; use a mandoline for the most consistent results. Keep slices submerged in cold water as you work to prevent browning. Grease a 9×13 baking dish with butter or non-stick spray.
Make the roux-based cream sauce. Melt butter in a medium saucepan over medium heat. Add minced garlic and cook 1 minute until fragrant. Stir in flour and cook, whisking constantly, about 2 minutes to remove the raw flour taste. Gradually whisk in warmed milk and heavy cream in a slow stream until smooth and slightly thickened. Season with salt, pepper, and nutmeg. Remove from heat and stir in 1 cup shredded cheddar until melted and glossy.
Layer & Bake
Layer potatoes and sauce. Drain and pat potato slices dry. Arrange one-third of the slices in overlapping rows in the baking dish, ladle one-third of the sauce over them, and sprinkle some Parmesan. Repeat twice, finishing with the remaining cheddar on top. Press layers gently to remove air gaps and ensure sauce covers exposed slices.
Bake covered, then uncover to brown. Tightly tent the dish with foil and bake for 45 minutes to steam the potatoes. Test a center slice with a thin knife; if it resists, bake an additional 10 minutes covered. Remove foil, increase oven to 375°F (190°C), and bake uncovered for 20–25 minutes until the top is deep golden and bubbly. Optionally broil on low for the final 2–3 minutes, watching closely to avoid burning.
Rest & Serve
Rest before serving. Remove from oven and let rest for 10 minutes to allow the sauce to set so slices hold their shape. Garnish with fresh parsley and serve warm. The casserole stays hot on a trivet for about 30 minutes for buffet service.

Expert Pro Tips
- Use a mandoline for uniform 1/8-inch slices to ensure even cooking.
- Warm milk and cream before adding to the roux to prevent lumps.
- Cook the roux for about 2 minutes to remove raw-flour taste.
- Press layers down as you assemble to remove air pockets and promote even sauce coverage.

Frequently Asked Questions
Can I make these scalloped potatoes ahead of time?
Yes — assemble up to 24 hours ahead and refrigerate. Allow about 20 minutes at room temperature before baking and add 10 minutes to the covered bake time if starting from cold.
Can I use different cheeses?
Absolutely. Gruyère, Fontina, or a blend of melting cheeses all work; avoid pre-shredded cheese with anti-caking agents for best melting results.
Why is my sauce lumpy?
Cold dairy added too quickly to a hot roux causes lumps. Warm milk and cream before adding and whisk constantly. If lumps form, strain the sauce before assembling.
What thickness should I slice the potatoes?
Shoot for a uniform 1/8-inch thickness. Consistency matters more than precise measurement — identical slices cook at the same rate.
My Final Take
This scalloped potatoes recipe produces a silky cheddar-Parmesan béchamel that bakes to golden, bubbly perfection in about 1 hour and 30 minutes. It’s dependable, economical, and adaptable — swap cheeses, add herbs, or fold in proteins to suit your menu. Leftovers keep well and reheat smoothly, making this a valuable recipe to have in your repertoire for weeknights and special occasions alike.
