Recipe for Smoked Ham and Sweet Potato Bake: Slow-Cooked Sweetness With Crispy Top

A smoked ham and sweet potato bake transforms simple ingredients into a showstopping centerpiece that smells like holiday dinner all day long. The secret lies in glazing the ham with just enough sweetness to caramelize beautifully while roasting the sweet potatoes until their edges turn crispy and golden.

I developed this recipe after years of perfecting the balance between tender ham, perfectly caramelized sweet potatoes, and that irresistible crispy top layer.

This dish is designed for effortless elegance—no fussy techniques required. You’ll start by scoring the ham and brushing it with a honey-mustard glaze that develops a sticky, caramelized crust. Meanwhile, the sweet potatoes roast until their flesh becomes tender and their edges develop that coveted crispy texture.

The combination of smoky ham and naturally sweet potatoes creates a flavor profile that’s both comforting and impressive.

By the time it emerges from the oven, you’ll have a dish that’s rich with flavor and visual appeal—a golden-brown ham surrounded by caramelized sweet potatoes with that perfect crispy top.

The aroma alone will have everyone gathering at the table, and each bite delivers a perfect balance of savory, sweet, and smoky notes. This is the kind of meal that feels special without requiring hours of prep.

The best part? This recipe scales beautifully for gatherings, and the leftovers reheat perfectly for sandwiches or hash the next day. Whether you’re hosting Thanksgiving or just craving a comforting Sunday dinner, this smoked ham and sweet potato bake delivers restaurant-quality results with minimal effort. Let’s get started!

The bone-in smoked ham is non-negotiable for that authentic, restaurant-quality flavor. Look for a center-cut piece with visible fat marbling—Costco or Whole Foods carry excellent options, but any quality grocery store should have one. If you can’t find skin-on, that’s okay, but the skin adds that extra crispy texture. Score the fat in a crosshatch pattern before roasting—this ensures the glaze penetrates deeply and creates those irresistible crispy pockets. For the sweet potatoes, medium-sized ones (about 6-8 oz each) roast evenly without turning mushy. Trader Joe’s often has the best selection of organic sweet potatoes, but any firm, unblemished ones will work.

No honey? Maple syrup works perfectly—just reduce it slightly to compensate for the extra moisture. Prefer a sharper glaze? Swap the Dijon for whole-grain mustard and add a pinch of smoked paprika. The butter in the glaze is crucial—full-fat, unsalted gives the best caramelization, but if you’re watching calories, use half butter and half Greek yogurt. Fresh herbs are ideal, but dried rosemary and thyme at half the amount will work in a pinch. For the garlic, roasted garlic adds a mellow sweetness that pairs beautifully with the smoky ham. If you’re short on time, jarred minced garlic is fine, but fresh is always better.

This dish reheats like a dream—5 minutes at 350°F brings it back to life, though it’s even better the next day when the flavors meld. Store leftovers in the fridge for up to 5 days, covered tightly to preserve that crispy top. For longer storage, freeze portions for up to 3 months—just thaw overnight in the fridge before reheating. The glaze can be made ahead and stored in the fridge for up to 1 week, so you can prep the night before and just brush it on fresh before roasting. The sweet potatoes can be peeled and cubed in advance, tossed with olive oil and a pinch of salt, then stored in the fridge for 24 hours before roasting.

Step-by-step instructions for smoked ham and sweet potato bake

Here’s how to achieve that perfect balance of slow-cooked sweetness and irresistibly crispy top.

Start by preheating your oven to 375°F. Peel the 3 lb sweet potatoes and cut them into 1-inch thick rounds, leaving the skin on for the first two rounds of each potato to help hold their shape. For the remaining rounds, peel completely to ensure even cooking.

In a large bowl, toss the sweet potatoes with 2 tbsp olive oil, 1½ tsp salt, and 1 tsp black pepper until they’re evenly coated. Spread them out on two parchment-lined baking sheets in a single layer. Roast for 25 minutes, flipping halfway through, until they begin to soften slightly and develop a faint golden color. This preliminary roasting ensures they’ll be tender when baked later while maintaining their shape.

While the sweet potatoes roast, prepare the glaze by combining ½ cup honey, ¼ cup brown sugar, 2 tbsp Dijon mustard, 1 tbsp apple cider vinegar, 4 minced garlic cloves, ¼ cup finely chopped fresh rosemary, and ⅛ cup finely chopped fresh thyme in a medium saucepan. Bring to a simmer over medium heat and cook for 5 minutes, stirring constantly, until the mixture thickens slightly and becomes fragrant.

Remove the 4 lb bone-in smoked ham from its packaging and place it fat-side up on a wire rack set over a baking sheet. Brush the entire surface of the ham generously with the glaze, making sure to get into all the crevices. This ensures even flavor distribution and that signature crispy bark we’re after. Set aside while you prepare the next layer.

In a large, deep baking dish (about 9×13 inches), create a base layer by placing half of the roasted sweet potatoes in an even layer. Arrange the 4 lb bone-in smoked ham on top of the sweet potatoes, fat-side up. This positioning allows the ham’s rendered fat to baste the sweet potatoes as they bake.

Add the remaining sweet potatoes around and on top of the ham, creating a snug arrangement. The sweet potatoes should be tightly packed but not forced. This ensures even cooking and prevents them from falling apart. In a small bowl, melt the ¼ cup unsalted butter and drizzle it evenly over the entire dish. This butter creates a luscious, golden crust on top while adding richness to the dish.

Cover the baking dish tightly with aluminum foil and bake at 375°F for 1 hour. This initial covered baking allows the sweet potatoes to cook through without drying out while the ham continues to render its fat. After 1 hour, remove the foil and increase the oven temperature to 425°F. This higher heat is crucial for developing that beautiful crispy top.

Return the dish to the oven and bake uncovered for an additional 20-25 minutes. You’ll know it’s done when the top is deep golden brown and the sweet potatoes are fork-tender. The ham should also be heated through with a crispy exterior. If the top starts browning too quickly, tent it loosely with foil for the last 5 minutes to prevent burning while still allowing it to crisp.

Remove the dish from the oven and let it rest for 10-15 minutes before serving. This resting period is essential—it allows the juices to redistribute throughout the ham and sweet potatoes, ensuring each bite is moist and flavorful. The crispy top will firm up slightly as it cools, making it easier to serve.

Slice the ham into ½-inch thick slices and arrange it on a serving platter with the sweet potatoes. The contrast of the crispy top on the sweet potatoes with the tender, juicy ham creates an unforgettable combination. Serve immediately with a simple green salad or crusty bread to soak up all those delicious juices.

Storing and reheating this dish

Fridge Storage Secrets

After baking, let your dish cool for 10 minutes before transferring to airtight containers—I use glass Pyrex with snap-on lids to preserve that crispy top. Store at 40°F or below for up to 5 days.

The flavors deepen overnight as the glaze continues to meld with the ham and sweet potatoes. Wrap any extra ham slices individually in foil to maintain moisture. 💫

Freezing Like a Pro

This dish freezes beautifully for up to 3 months without losing texture. I recommend quart-sized freezer bags for easy stacking and quick thawing. Place the dish in the bag, squeeze out excess air, and lay flat to save space.

Label with the date—this ensures you’ll use it before the flavors fade. Thaw overnight in the fridge for even reheating. ❄️

Reheating Without Ruining It

For stovetop reheating, pour leftovers into a heavy-bottomed skillet and add ¼ cup water or broth. Heat over medium-low for 10 minutes, stirring occasionally, until the crispy top regains its golden hue.

This prevents drying out while maintaining that perfect texture. Taste and adjust seasoning—sometimes a pinch of salt helps revive the flavors. 🔥

Microwave Rescue

When time is tight, microwave portions covered with a damp paper towel on 70% power for 2-3 minutes. Stir, then continue in 1-minute intervals until reaching 165°F internally. Add a splash of water if the top looks dry.

While not as crispy, this method works well for quick lunches. I avoid microwaving the entire dish—it ruins the crispy texture. 💡

Reviving the Crispy Top

If your leftovers lose their crispiness, don’t worry! Return them to the oven at 350°F for 5-7 minutes uncovered. The residual heat will revive that golden crust. For extra crispiness, brush with a little melted butter before reheating. This trick works wonders for both ham and sweet potatoes. 🍯

Leftovers Get-Up-and-Go Ideas

Repurpose leftovers into sweet potato hash by dicing and pan-frying with a little olive oil and thyme. Or make ham and sweet potato sandwiches with a smear of Dijon mustard and arugula. The flavors are even more concentrated after reheating—perfect for lunch the next day! 🥪
