I like to pair this Ham and Potato Au Gratin with a crisp green salad tossed with a light vinaigrette or steamed green beans to add a pop of color and some freshness to the meal.

Step 3: Layer the Au Gratin

1. In the prepared baking dish, arrange half of the sliced potatoes in an even layer.
2. Sprinkle half of the diced ham over the potatoes.
3. Pour half of the cheese sauce over the potatoes and ham.
4. Repeat with the remaining potatoes, ham, and cheese sauce.
5. Top with the remaining shredded cheese, Parmesan, and a light sprinkle of paprika for a golden finish.

Step 4: Bake the Au Gratin

1. Cover the dish with aluminum foil and bake for 30 minutes.
2. Remove the foil and bake for an additional 20–25 minutes, until the potatoes are tender and the top is golden and bubbly.
3. Allow to rest for 5–10 minutes before serving.

Step 5: Prepare the Crisp Green Salad

1. In a large salad bowl, combine the mixed greens, cucumber, cherry tomatoes, and red onion.
2. Drizzle with olive oil and balsamic vinegar (or lemon juice).
3. Toss gently to coat evenly and season with salt and pepper to taste.

Step 6: Steam the Green Beans (Optional)

1. Bring a pot of salted water to a boil.
2. Add the trimmed green beans and cook for 3–4 minutes until tender-crisp.
3. Drain and toss with butter or olive oil, if desired.

Step 7: Plate and Serve

1. Serve a generous portion of the ham and potato au gratin alongside a crisp green salad or a side of steamed green beans.
2. Enjoy the contrast of creamy, cheesy richness with fresh, bright vegetables that add color, texture, and a refreshing balance.

Tips for Perfection

• Even slicing: Use a mandoline or sharp knife to slice potatoes evenly, ensuring uniform cooking.
• Make ahead: The au gratin can be assembled a day ahead and baked just before serving.
• Cheese variations: Gruyère, Fontina, or Swiss can add a nutty depth to the dish.
• Extra flavor: Sprinkle a few fresh thyme leaves over the top before baking for an herbal aroma.

This Ham and Potato Au Gratin paired with a crisp green salad or steamed green beans is a comforting yet balanced meal that’s perfect for family dinners or special occasions. The creamy potatoes and ham contrast beautifully with the light, fresh vegetables, making every bite satisfying and vibrant.

If you want, I can also create a shortcut one-pan version that combines everything for a quicker, minimal-cleanup dinner without losing any flavor. Do you want me to do that?
