Betty Crocker Au Gratin Potatoes and Ham Recipe: One-Pan Holiday Showstopper

Betty Crocker's au gratin potatoes with ham bring that cozy holiday aroma to your dinner table with minimal effort. 💛 This one-pan classic combines tender potatoes, savory ham, and a rich cheese-cream sauce that browns beautifully in the oven.

I've perfected the layering technique to ensure every bite delivers creamy texture and crispy edges—just like your grandmother's famous version.

The secret lies in properly browning the ham and slicing the potatoes evenly for even cooking. You'll start with a flavorful base of cooked ham, then layer thinly sliced potatoes in a single layer before pouring the creamy sauce over the top.

The result is a dish that's restaurant-quality but simple enough for any home cook to master.

By the time it emerges from the oven, you'll have golden-brown potatoes with bubbling cheese sauce on top and crispy edges that hold their shape. The savory ham adds depth, while the creamy sauce ties everything together into one comforting, holiday-worthy side dish.

This recipe serves 6-8 and takes just 45 minutes to prepare.

Perfect for Thanksgiving, Christmas dinner, or any special occasion when you want to impress without stress. The best part? It all goes into one pan, making cleanup a breeze. Let's create this timeless holiday classic together.

Ingredients for betty crocker au gratin potatoes and ham

Holiday flavors in one pan—creamy, cheesy, and packed with ham aroma. Simple staples, big comfort.

The potatoes are the star, so pick Russets—they hold up best to slicing and baking. Trader Joe's or Costco usually have them pre-bagged for easy slicing. If you're slicing by hand, use a mandoline for even thickness (about 1/8-inch). The ham? Black Forest or honey-glazed adds that sweet-savory holiday touch. I always buy pre-sliced to save time, but if you're ambitious, thinly slice it yourself for better presentation. For the cheeses, freshly shredded is key—pre-shredded gets clumpy and lacks flavor. Grab a block of sharp cheddar and Gruyère at Whole Foods or your local deli counter if you want to splurge.

No heavy cream? Half-and-half plus a splash of milk works in a pinch, but the texture won't be as rich. Short on Gruyère? Swiss cheese is a decent stand-in, though it's milder. The flour is just for thickening—if you're gluten-free, use cornstarch instead. For the garlic, fresh is non-negotiable—jarred minced has a metallic taste. Love thyme but forgot to buy it? Dried oregano at half the amount gives a similar earthy note. The panko topping? Toast it lightly in the oven first for extra crunch—trust me on this. And if you're watching calories, you can cut the butter by half and use olive oil instead.

This dish reheats beautifully—just cover with foil and warm in the oven for 10 minutes. Keeps for 3-4 days in the fridge, though it's best served fresh. For make-ahead convenience, assemble the dish (without baking) and refrigerate overnight. The flavors meld even better the next day. Leftovers? Portion into containers and freeze for up to 3 months. The sauce might separate when frozen, so stir it well before reheating. And if you're serving at a holiday gathering, make it in a 9x13-inch baking dish—it's the perfect size for sharing.

Step-by-step instructions for holiday au gratin potatoes and ham

This one-pan masterpiece delivers restaurant-quality comfort with minimal effort—perfect for your holiday table.

Preheat your oven to 375°F and grease a 9x13-inch baking dish with the 1 tablespoon extra-virgin olive oil. Peel and thinly slice the 3 lb russet potatoes (about ⅛-inch thick) using a mandoline or sharp knife. I like to slice them while holding the potato against the cutting board—this gives you more control and safer cuts.

Arrange the potato slices in overlapping rows in the prepared baking dish, slightly offsetting each layer like brickwork. This creates a stable base that won't collapse when you add the ham and cheese. You should have about 4-5 layers of potatoes. Sprinkle each layer with ⅓ of the 1.5 tsp salt and ⅓ of the 0.5 tsp ground black pepper as you go. This ensures even seasoning throughout the dish.

In a medium saucepan, melt the 0.5 cup unsalted butter over medium heat. Whisk in the 0.25 cup all-purpose flour and cook for 1-2 minutes until bubbly but not browned. This creates a roux that will thicken your sauce beautifully. Slowly pour in the 1.5 cups heavy cream and 0.5 cup whole milk while whisking constantly to prevent lumps.

Bring the mixture to a gentle simmer and cook for 3-4 minutes until it thickens enough to coat the back of a spoon. Stir in the 4 minced garlic cloves, 1 tsp dried thyme, and remaining 1 tsp salt and 0.25 tsp ground black pepper. Remove from heat and fold in the 1 lb thinly sliced black forest ham. Pour this creamy ham mixture evenly over the layered potatoes, pressing down gently to help it settle between the slices.

Sprinkle the 2 cups shredded sharp cheddar cheese and 0.5 cup shredded gruyère cheese evenly over the ham mixture. The cheddar will melt into a rich, tangy sauce while the gruyère adds nutty depth—trust me, this combo is unbeatable. Cover the baking dish tightly with aluminum foil and bake for 45 minutes.

Here's where the magic happens: the foil traps steam, creating a tender interior while preventing the top from browning too quickly. After 45 minutes, remove the foil and bake for another 15-20 minutes until the top is golden brown and bubbly. You'll know it's ready when the edges pull away slightly from the pan and the cheese has formed a delicious crust.

While the potatoes finish baking, mix the 0.25 cup panko breadcrumbs with 1 tablespoon melted unsalted butter in a small bowl. The panko should look evenly coated and slightly clumpy—this creates that perfect crispy texture we're after. Spoon the buttered breadcrumbs evenly over the top of the au gratin just as it comes out of the oven.

Return the dish to the oven for 5-7 minutes on broil high until the breadcrumbs are deep golden brown and the cheese underneath is fully melted. Watch it closely—the broiler works fast, and you want that topping to be crispy, not burnt. The moment the breadcrumbs turn golden and the cheese bubbles vigorously, it's time to remove from the oven.

Let the au gratin rest for 10-15 minutes before serving. This resting period allows the layers to set slightly and makes it much easier to slice cleanly. The potatoes should be tender enough to pierce easily with a fork, and the ham should be warm throughout. If you're serving this as a side dish, you might want to slice it into squares for neat presentation.

Here's my pro tip: serve immediately with a dollop of sour cream or a sprinkle of fresh parsley. The contrast of cool sour cream against the warm, creamy potatoes is pure comfort food magic. And if you have leftovers (unlikely, but possible), reheat them covered in the oven at 350°F until warmed through—they'll be just as delicious the next day.

Health benefits of this dish

Protein-Packed Comfort

This dish delivers a satisfying 15-20 grams of protein per serving thanks to the ham and cheese combination. The 1 lb Black Forest ham provides lean protein while adding savory depth, while the 2.5 cups of shredded cheese contributes casein protein that digests slowly, keeping you full longer.

Perfect for holiday meals when you need hearty sides that satisfy without weighing you down. 💪

Creamy Goodness

The heavy cream and butter create a rich sauce that delivers healthy fats your body needs, particularly monounsaturated fats from the butter that support heart health. These fats also help your body absorb the fat-soluble vitamins (A, D, E, K) from the cheese.

I always use full-fat dairy because the flavor and texture are worth the extra calories.

Vitamin Boost

Potatoes are nutritional powerhouses in this dish, providing vitamin C (about 30% daily value per serving) and potassium (essential for blood pressure regulation). The Gruyère cheese adds vitamin B12 and calcium, while the thyme contributes antioxidants.

Together, they create a surprisingly balanced side dish that feels indulgent but actually nourishes you.

Holiday Stress Relief

Comfort foods like this release serotonin and dopamine, the "feel-good" neurotransmitters that reduce stress. The warm, creamy texture and familiar flavors trigger these chemical responses, making it an excellent dish for holiday gatherings when emotions run high.

Plus, the one-pan preparation means less stress for you in the kitchen! ✨

Low-Carb Adaptation

For a lighter version, replace half the potatoes with cauliflower florets (about 1.5 cups) layered between the potato slices. The cream sauce and cheese will still provide richness while cutting carbs.

I've tested this adaptation and found it works beautifully—just add the cauliflower in the final layer so it doesn't get soggy.

Meal Prep Benefits

This dish reheats beautifully, making it perfect for meal prepping holiday leftovers. The cheese sauce helps lock in moisture, so portions stay creamy even after reheating. I recommend storing in glass Pyrex containers with tight lids to preserve texture.

The flavors actually improve overnight as the spices meld together—perfect for busy weeknights after the holidays! 📅
