This step-by-step guide will walk you through prepping, layering, and baking your gratin to cheesy bliss. From crafting a smooth roux to assembling the layers with care, you’ll learn how to get those potatoes perfectly tender and the top irresistibly golden.
1. Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with butter or cooking spray so the gratin won’t stick.
2. In a large skillet over medium heat, melt 4 tablespoons unsalted butter. Add the minced garlic and sauté for about 1 minute until fragrant.
3. Stir in the flour and cook for 1–2 minutes, creating a roux. Gradually whisk in the heavy cream and whole milk, ensuring no lumps remain. Continue to cook for about 5 minutes until the sauce thickens and coats the back of a spoon.
4. Add the onion powder, salt, black pepper, and cayenne pepper (if using) to the sauce. Stir well, then remove from heat.
5. In the prepared baking dish, layer half of the potato slices evenly across the bottom. Top with half of the diced ham and sprinkle with half of the shredded cheddar cheese.
6. Pour half of the cream sauce over this first layer, making sure the potatoes are mostly submerged.
7. Repeat the layering process with the remaining potatoes, ham, and cheese. Finish by pouring the rest of the cream sauce over the top.
8. Cover the dish with aluminum foil and bake in the preheated oven for 40 minutes to allow the potatoes to soften.
9. After 40 minutes, remove the foil and bake uncovered for an additional 20 minutes, or until the top is golden brown and bubbling.
10. Let the gratin rest for about 10 minutes before serving. Garnish with chopped parsley for a fresh pop of color.

Here are some quick answers to common questions about preparing, customizing, and storing your Ham and Potato Au Gratin.
A: Yes. You can assemble the layers up to step 7, cover the baking dish with foil, and store it in the refrigerator for up to 24 hours. When ready to bake, remove from the fridge, let it sit at room temperature for 15–20 minutes, then proceed with the 40-minute covered bake and 20-minute uncovered bake, adding an extra 5–10 minutes if needed for a hot, bubbly top.
A: Use a sharp knife or a mandoline to cut the russet potatoes into uniformly thin (about 1/8-inch) slices. Even thickness ensures they cook at the same rate, preventing undercooked centers or overly soft edges.
A: You can substitute low-fat milk for whole milk, but the sauce may be thinner and less rich. If you reduce the heavy cream, the gratin won’t be as creamy or hold together as well. For best results, stick with the original ratios or consider using half-and-half instead of all heavy cream.
A: Remove the foil for the last 20 minutes of baking to let the cheese brown. If the top starts to brown too quickly, lower the oven temperature by 25°F or tent loosely with foil for the final 5–10 minutes. You can also switch to the broiler for 1–2 minutes, watching closely.
A: Absolutely. Fold in 1–2 cups of cooked, chopped broccoli, spinach, or mushrooms between the layers to add color and nutrients. Ensure any added veggies are well drained to avoid excess moisture in the gratin.
A: Cover leftovers and refrigerate for up to 3 days. To reheat, place individual portions in a microwave for 2–3 minutes until hot, or return the entire dish to a 350°F oven, covered, for 15–20 minutes, then uncover for 5 minutes to crisp the top.
A: Letting the gratin rest for about 10 minutes after baking allows the sauce to thicken and the layers to set. This makes it easier to cut clean portions and prevents the cream from running off the slices.
