Betty Crocker Au Gratin Potatoes Recipe: Cheesy Layers of Homemade Comfort

There’s nothing like the homemade warmth of cheesy potatoes bubbling straight from the oven. This dish brings layers of tender slices smothered in a creamy sauce, topped with golden breadcrumbs for that perfect crunch.

I developed this version to capture that classic comfort food feeling without complicated techniques. The secret lies in layering thin potato slices with a rich cheese sauce that bakes into creamy perfection.

What emerges is a side dish with crispy edges, creamy centers, and that nostalgic flavor we all crave. The cheese melts into every layer, creating a dish that’s as satisfying as it is simple.

Perfect alongside roasted meats or as a vegetarian main. Here’s how to make this timeless favorite.

Ingredients for Betty Crocker Au Gratin Potatoes

Pantry staples and fresh potatoes come together for this comforting, cheesy bake.

The potatoes are the star here. Russets give you that perfect fluffy texture—don’t swap for waxy varieties. Most grocery stores carry them year-round. I grab mine from Kroger when they’re on sale, but any supermarket works. Look for firm potatoes with smooth skin (no sprouts or green spots). For the cheddar, block cheese shredded at home melts way better than pre-shredded.

No sharp cheddar? Monterey Jack or Colby work great—similar melt, milder flavor. Out of whole milk? Half-and-half at half the quantity keeps it creamy. Skip the Dijon? A pinch of dry mustard gets you close. The panko can be regular breadcrumbs (toasted first for crunch). If you’re short on time, pre-sliced potatoes from the grocery store save a step.

Assemble and refrigerate up to 24 hours before baking. Leftovers keep 3-4 days in the fridge—reheat covered to prevent drying. Freezes beautifully for 2 months (thaw overnight before reheating).

Step-by-Step Instructions for Cheesy Au Gratin Potatoes

Here’s how I make this creamy, comforting dish with perfectly crispy topping every time.

Step 1: Prepare the Potato Slices and Cheese Sauce Base

Peel the 2 lb Russet Potatoes and slice them into ⅛-inch thick rounds using a sharp knife or mandoline. I like to soak the slices in cold water for 5 minutes to remove excess starch, then pat them completely dry with a clean towel.

In a saucepan, melt the 4 tbsp Unsalted Butter over medium heat. Add the 0.25 cup All-Purpose Flour and whisk constantly for 1-2 minutes until the mixture turns light golden brown and smells nutty. This creates a smooth roux that will thicken your sauce perfectly.

Step 2: Build the Creamy Cheese Sauce

Slowly pour in the 1.5 cups Whole Milk while whisking continuously to prevent lumps. Add the 1 tsp Dijon Mustard, 1 tsp Salt, 0.5 tsp Black Pepper, and 0.5 tsp Onion Powder. Cook for 3-4 minutes, stirring constantly, until the sauce thickens enough to coat the back of a spoon.

Remove the sauce from heat and stir in 1.5 cups of the 2 cups Sharp Cheddar Cheese until fully melted and smooth. I always reserve some cheese for the topping. The sauce should be thick but pourable—if it’s too thick, add a splash more milk.

Step 3: Layer the Potatoes and Sauce

Grease a 9×13-inch baking dish and start layering. Spread a thin layer of sauce on the bottom, then add a single layer of potato slices, slightly overlapping. Repeat with sauce, potatoes, and minced 2 cloves Garlic Cloves until all potatoes are used, ending with sauce on top.

Sprinkle the remaining 0.5 cup Sharp Cheddar Cheese evenly over the top. At this point, you can cover and refrigerate for up to 24 hours before baking, or proceed immediately to the next step.

Step 4: Add the Crispy Topping and Bake

In a small bowl, mix the 0.75 cup Panko Breadcrumbs with the 0.5 cup Parmesan Cheese. Sprinkle this mixture evenly over the cheesy potatoes, pressing down lightly so it adheres. This creates that irresistible crispy crust that contrasts with the creamy layers below.

Bake uncovered at 375°F for 45-50 minutes until the top is golden brown and the sauce is bubbling around the edges. If the top browns too quickly, tent with foil for the remaining cooking time.

Step 5: Rest and Garnish Before Serving

Let the dish rest for 10 minutes after removing from the oven. This allows the layers to set so you get clean, beautiful servings rather than a runny mess. The potatoes should be tender enough to cut with a fork and the sauce should be creamy, not watery.

Just before serving, sprinkle with the 2 tbsp Fresh Parsley for a pop of color and freshness. This dish is best served hot from the oven, with each portion showcasing those perfect cheesy layers and crispy topping.

Perfect Pairings for These Flavors

Protein Pairings

I love serving these potatoes with a simple roasted chicken—the crispy skin and juicy meat complement the creamy layers beautifully. A 4 lb whole chicken roasted at 425°F for 1 hour 15 minutes gives you perfect timing to bake them together.

Vegetable Sides

A bright green salad with a tangy vinaigrette cuts through the richness. I toss 6 cups mixed greens with 3 tbsp olive oil and 1 tbsp balsamic vinegar. Or try roasted Brussels sprouts—toss 1 lb halved sprouts with 2 tbsp olive oil and roast at 400°F for 20-25 minutes. 🥗

Bread Options

A warm crusty baguette or sourdough loaf soaks up any extra cheesy sauce. I grab mine from the local Italian deli—look for one with a crisp crust and airy interior. Toast slices lightly before serving for extra crunch.

Wine Pairings

A crisp Chardonnay with its buttery notes mirrors the dish’s creaminess. For red lovers, a light Pinot Noir won’t overpower the flavors. I always serve wine slightly chilled, even reds—about 10 minutes in the fridge. 🍷

Comfort Meal Upgrade

Turn this into a full meal by adding a simple protein like baked ham or meatloaf. The potatoes also pair well with grilled sausages—I love Italian sweet sausage for that family-dinner feel.
