Butter – For a silky base that brings all the flavors together with a luscious mouthfeel.
All-purpose flour – Creates the perfect thickener for the creamy cheese sauce without lumps.
Whole milk – Use full-fat for the creamiest, most indulgent bake.
Garlic – Mince finely to infuse subtle aromatic warmth throughout the dish.
Onion – Thinly sliced for sweetness and added depth in every bite.
Salt and black pepper – Essential seasonings to enhance the natural flavors of the Cheesy Scalloped Potato Bake.

How to Make Cheesy Scalloped Potato Bake

Preheat oven: Preheat to 375°F (190°C) and butter a 9×13-inch baking dish, ensuring even coating to prevent sticking and encourage golden edges during baking.
Slice potatoes: Thinly slice about 2 pounds of russet potatoes (⅛-inch thick) using a mandoline or sharp knife for uniform cooking and tender, creamy layers throughout.
Sauté aromatics: Melt butter over medium heat in a saucepan, then add thinly sliced onion and minced garlic. Cook until onions are soft and translucent, about 3–4 minutes.
Make sauce: Whisk in all-purpose flour to form a roux, then gradually pour in whole milk. Stir constantly until sauce is smooth and thickened, about 5 minutes.
Add cheese: Remove sauce from heat and stir in sharp cheddar until fully melted and silky, creating a glossy, amber-colored cheese sauce.
Layer layers: Arrange half the potato slices in the dish, pour half the cheese sauce evenly, sprinkle half the cheddar, then repeat for two luscious, creamy tiers.
Top bake: Finish with an extra layer of cheddar (and Parmesan if using), then bake uncovered at 375°F for 35–40 minutes, until bubbly and golden brown.
Rest & serve: Let the casserole rest 10 minutes before slicing; this helps the sauce set slightly for clean, decadent wedges that hold together beautifully.

Optional: Garnish with fresh thyme leaves for a fragrant, rustic finish.

Avoid Lumpiness: Whisk the flour and butter roux continuously before adding milk slowly to prevent lumps in your cheese sauce.
Patience Resting: Let the bake rest 10 minutes after coming out of the oven; this lets the sauce thicken for cleaner, sturdier servings.

Make Ahead Options

Preparing your Cheesy Scalloped Potato Bake ahead of time is a fantastic way to save precious minutes on busy weeknights!

When you’re ready to serve, simply reheat the sauce until warm, layer over the prepped potatoes, and bake as directed. This allows you to enjoy a comforting, homemade meal without any last-minute fuss!

Cheesy Scalloped Potato Bake Recipe FAQs

What type of potatoes work best for Cheesy Scalloped Potato Bake?
Russet potatoes are ideal because they are starchy and soften beautifully, creating those tender, creamy layers that define this dish. Avoid waxy potatoes, as they won’t achieve the same melt-in-your-mouth texture.

How should I store leftover Cheesy Scalloped Potato Bake, and how long will it keep?
Store leftovers in an airtight container in the refrigerator for up to 3 days. Covering it well prevents the potatoes from drying out. When reheating, add a splash of milk to revive the creamy texture and warm gently.

Can I freeze Cheesy Scalloped Potato Bake? If so, what’s the best method?
Absolutely! After baking, let the dish cool completely. Wrap it tightly first in plastic wrap, then in foil to prevent freezer burn. Freeze for up to 2 months. When ready to eat, thaw overnight in the refrigerator, then reheat in a 350°F oven for 25-30 minutes until evenly hot. Cover during reheating to keep moisture, uncover near the end for a crisp, golden top.

My cheese sauce turned out lumpy—how can I fix or avoid this?
Lumpiness usually happens if the flour-butter mixture (roux) isn’t whisked constantly before slowly adding milk. To fix lumps, whisk vigorously over medium heat until smooth or strain the sauce. Patience and steady stirring during sauce preparation are key to that silky, creamy cheese blend.

Is this recipe safe for pets or people with allergies?
This bake contains dairy, flour, and onions, which are not suitable for dogs or people with lactose intolerance or gluten allergies.
