Stouffer’s Cheddar Potato Bake Copycat Recipe: Loaded Cheesy Layers in One Pan

This copycat version brings the nostalgic comfort of cheesy potato layers right to your kitchen. My grandmother’s handwritten notes inspired this recreation of the classic Stouffer’s dish.

Thinly sliced potatoes bake between creamy cheddar sauce and crispy toppings, just like the original. The layers melt together into perfectly tender bites with golden edges.

I’ve tested this recipe multiple times to match that familiar taste and texture. The secret is in the sauce distribution and baking time.

One pan, simple ingredients, and the same satisfying results you remember. This is comfort food made exactly as it should be.

The potatoes are the foundation here. Russets give you that perfect flaky texture—avoid waxy varieties like red or Yukon Gold. I grab mine from Costco for consistent quality and size. The cheddar needs to be block cheese you shred yourself; pre-shredded has anti-caking agents that make the sauce grainy. For the milk, whole is essential (trust me on the full-fat version) for that creamy sauce.

No sharp cheddar? Colby or Monterey Jack work in a pinch but lack that tangy bite. Swap the corn flakes for crushed Ritz crackers or panko for extra crunch. If you’re out of dry mustard, a pinch of mustard powder does the trick. The vegetarian Worcestershire is key—Annie’s makes a great version. Fresh garlic is non-negotiable; jarred just doesn’t have the same punch.

Assemble this the night before and refrigerate—just add 10 minutes to the bake time. Leftovers keep 4-5 days in the fridge, but the topping loses its crunch. Reheat covered with foil to prevent drying out. Honestly, this tastes even better the next day (worth the extra minute).

Step-by-Step Instructions for Cheddar Potato Bake

Here’s how to layer and bake this dish to cheesy, creamy perfection in one pan.

Step 1: Prep the Potatoes and Make the Cheese Sauce

Peel and thinly slice the 2 lb Russet Potatoes into ⅛-inch rounds for even cooking. As you work, place the slices in a bowl of cold water to prevent browning. Meanwhile, melt the 4 tbsp Unsalted Butter in a saucepan over medium heat.

Add the finely diced Yellow Onion and cook for 3-4 minutes until translucent. Stir in the minced 2 cloves Garlic Cloves and cook for 30 seconds until fragrant. This builds the aromatic base for your sauce.

Whisk in the 0.25 cup All-Purpose Flour, 0.5 tsp Dry Mustard, 1.5 tsp Salt, and 0.5 tsp Black Pepper, creating a smooth roux. Gradually pour in the 2 cups Whole Milk and 1 tsp Worcestershire Sauce, whisking constantly until thickened to the consistency of heavy cream.

Step 2: Layer Potatoes and Sauce

Drain the potato slices and pat them dry with a clean towel. Lightly grease a 9×13-inch baking dish and begin layering. Start with a third of the potato slices, slightly overlapping them. Pour a third of the sauce over the top, then sprinkle with 1 cup of the 3 cups Sharp Cheddar Cheese.

Repeat with another layer of potatoes, sauce, and cheese. Finish with the remaining potatoes, then pour the rest of the sauce evenly over the top. Reserve the final 1 cup Sharp Cheddar Cheese for the topping. This layering ensures every bite is packed with cheesy flavor.

Step 3: Add the Crispy Topping and Bake

In a small bowl, crush the 1 cup Corn Flakes into coarse crumbs. Mix with the remaining 1 cup Sharp Cheddar Cheese and the 2 tbsp Melted Butter. Sprinkle this mixture evenly over the top of the casserole, pressing down lightly so it adheres.

Cover the dish with foil and bake at 375°F for 45 minutes. Then, remove the foil and bake for another 20-25 minutes until the top is golden brown and the potatoes are tender when pierced with a knife.

Step 4: Rest and Serve

Let the casserole rest for 10 minutes after removing it from the oven. This allows the sauce to thicken and the layers to set, making it easier to serve neat portions. The edges should be bubbling, and the topping should have a satisfying crunch.

Scoop onto plates while still warm. Each serving should showcase the creamy sauce, tender potatoes, and crispy, cheesy topping. The flavors meld beautifully during baking, delivering that nostalgic, comforting taste in every bite.

Storing and Reheating This Dish

Refrigerator Storage

Let this dish cool for no more than 2 hours before transferring to airtight containers. I use glass dishes with tight lids for best results. Store in the fridge at 40°F or below for up to 4-5 days. The flavors actually improve overnight. ❄️

Freezer Storage

For longer storage, wrap individual portions tightly in plastic wrap then foil. Freeze for up to 3 months without quality loss. I recommend labeling with the date—trust me, you’ll forget. Thaw overnight in the fridge before reheating.

Oven Reheating

Preheat oven to 350°F. Cover the dish with foil and bake for 20-25 minutes until heated through. For that crispy topping, uncover for the last 5 minutes. This method keeps the potatoes tender and the sauce creamy. 🔥

Microwave Method

Place a single portion on a microwave-safe plate, cover with a damp paper towel, and heat on 70% power for 2-3 minutes. Stir halfway through. Add a splash of milk if it looks dry. Not as good as oven, but quick.

Make-Ahead Tip

Assemble the casserole the night before and refrigerate. Add 10 minutes to the bake time. This is perfect for busy weeknights. Honestly, it tastes even better the next day—worth the extra minute.
