Ingredients

2 boxes (4.7 oz each) Betty Crocker Au Gratin Potatoes or Scalloped Potatoes mix (including seasoning packets)
2 cups (about 12 oz) pre-diced cooked ham (such as Great Value or Creed Value Diced Ham, or leftover ham)
1 can (10.5 oz) Campbell’s Condensed Cream of Mushroom Soup (or Cream of Chicken)
1 jar (15 oz) Prego Creamy Alfredo Sauce
1 cup milk (whole or 2%)
1/2 cup water
2 cups shredded sharp cheddar cheese, divided
1 cup frozen or canned corn, drained (optional)
1/2 teaspoon black pepper
1/4 teaspoon garlic powder (optional)
Fresh parsley, chopped, for garnish (optional)

Instructions

Lightly grease the inside of a 6-quart or larger slow cooker with cooking spray.
In a large mixing bowl, combine the contents of both potato seasoning packets (from the au gratin/scalloped potato boxes), condensed cream of mushroom soup, Alfredo sauce, milk, water, black pepper, and garlic powder (if using). Whisk until well combined and smooth.
Add the thinly sliced potatoes from both boxes to the sauce mixture. Stir gently to ensure all potato slices are coated.
Add the diced ham and corn (if using) to the bowl with the potato mixture. Stir everything together until evenly distributed.
Pour half of the potato, ham, and sauce mixture into the prepared slow cooker. Spread it out evenly.
Sprinkle 1 cup of the shredded sharp cheddar cheese over the first layer.
Pour the remaining potato, ham, and sauce mixture over the cheese layer in the slow cooker, spreading it out evenly.
Cover the slow cooker and cook on LOW for 4-5 hours, or on HIGH for 2.5-3 hours, or until the potatoes are tender when pierced with a fork. Cooking times can vary based on your slow cooker, so check for doneness.
During the last 30 minutes of cooking, remove the lid and sprinkle the remaining 1 cup of shredded sharp cheddar cheese over the top of the casserole.
Replace the lid and continue cooking until the cheese is melted and bubbly.
Once cooked, turn off the slow cooker and let the casserole rest for 10-15 minutes before serving. This allows the sauce to thicken slightly.
Garnish with fresh chopped parsley, if desired, and serve hot.

Cooking Tips and Variations

Achieving the perfect Slow Cooker Cheesy Ham & Scalloped Potato Casserole is all about a few key tips and knowing how to adapt it to your taste. First and foremost, potato tenderness is paramount. Different slow cookers can have varying temperatures, so always check the potatoes by piercing them with a fork. If they’re not soft, give them another 30-60 minutes. Don’t rush this step, as undercooked potatoes can be unappetizing. For an even creamier result, you can stir in 1/4 cup of cream cheese or sour cream during the last hour of cooking, which adds a wonderful tang and richness.

Ingredient flexibility is a major advantage of this recipe. While we’ve specified convenience ingredients for ease, feel free to swap them out. If you have leftover ham from a holiday dinner, dice it up and use it instead of canned or pre-packaged ham. For the potato mixes, any brand of au gratin or scalloped potatoes will work; just ensure it’s the kind with the thinly sliced dried potatoes and seasoning packets. If you prefer a stronger cheese flavor, consider using a blend of sharp cheddar and Gruyere, or even a smoked Gouda. The Alfredo sauce can also be substituted with a cream of chicken or cream of celery soup for a slightly different flavor profile, though the Alfredo provides a unique richness.

To boost the nutritional value and add more color, incorporating extra vegetables is a fantastic idea. Frozen peas, diced bell peppers (red or green work well), or even a handful of chopped spinach can be stirred in with the ham and potatoes. If you enjoy a bit of heat, a pinch of cayenne pepper or red pepper flakes mixed into the sauce will add a pleasant kick. For a smoky twist, consider replacing some of the diced ham with diced smoked sausage or kielbasa, which adds a deeper, more robust flavor. Remember to adjust seasoning to taste – a little extra black pepper or a dash of onion powder can really make the flavors pop.

For those who love a crispy topping, you can transfer the cooked casserole to an oven-safe dish after the slow cooking is complete, sprinkle with extra cheese and a handful of panko breadcrumbs mixed with a tablespoon of melted butter, and broil for 3-5 minutes until golden brown and bubbly. This adds a delightful textural contrast. If your sauce seems a little thin after cooking, simply remove the lid for the last 30 minutes to allow some moisture to evaporate, or stir in a tablespoon of cornstarch mixed with a little cold water to thicken it up. Conversely, if it seems too thick, a splash of milk or broth can thin it out. Finally, always let the casserole rest for 10-15 minutes after cooking before serving; this allows the liquids to redistribute and the casserole to set, making it easier to scoop and preventing it from being too watery.

Storage and Reheating

This Slow Cooker Cheesy Ham & Scalloped Potato Casserole makes fantastic leftovers, perfect for meal prepping or quick lunches throughout the week. To store, allow the casserole to cool completely to room temperature first. This is crucial to prevent condensation from forming inside the container, which can make the casserole watery and promote bacterial growth. Once cooled, transfer the casserole to an airtight container. It can be stored in the refrigerator for up to 3-4 days. For longer storage, you can freeze individual portions. Place cooled casserole in freezer-safe airtight containers or heavy-duty freezer bags, removing as much air as possible to prevent freezer burn. It will keep well in the freezer for up to 2-3 months.

When reheating, there are several convenient options depending on whether it’s refrigerated or frozen. From the refrigerator, individual portions can be easily reheated in the microwave. Place a serving on a microwave-safe plate, cover loosely with a microwave-safe lid or plastic wrap, and heat on high for 1-2 minutes, stirring halfway through, until heated through. For a larger portion or if you prefer a less “microwaved” texture, reheat in the oven. Transfer the desired amount to an oven-safe dish, cover with foil, and bake at 300°F (150°C) for 15-20 minutes, or until warmed through. You can remove the foil for the last few minutes if you want to crisp up the cheese topping slightly.

If reheating from frozen, it’s best to thaw the casserole in the refrigerator overnight before reheating, especially if using the microwave or stovetop method. If reheating directly from frozen, the oven is your best bet. Place the frozen casserole (covered with foil) in an oven-safe dish and bake at 325°F (160°C) for 45-60 minutes, or until heated through to the center. Cooking time will vary significantly based on the portion size. For microwave reheating from frozen, this is best for smaller, individual portions. Heat on 50% power for 3-5 minutes, then increase to high power and continue heating in 1-minute intervals, stirring occasionally, until hot. Be patient, as heating from frozen in the microwave can take longer and may result in uneven heating. Always ensure the casserole reaches an internal temperature of 165°F (74°C) for food safety.

Frequently Asked Questions

Can I prepare this casserole ahead of time and cook it later?

Yes, you absolutely can! To prepare ahead, assemble all ingredients in the slow cooker as directed, but do not turn it on. Cover the slow cooker insert with plastic wrap or its lid and refrigerate for up to 24 hours. When you’re ready to cook, remove it from the refrigerator and let it sit at room temperature for about 30 minutes while your slow cooker preheats slightly. Then, cook as per the instructions, but you might need to add an extra 30-60 minutes to the total cooking time, especially if the ingredients are still very cold, to ensure the potatoes are fully tender.

What if my potatoes are still hard after the recommended cooking time?

Slow cooker temperatures can vary, leading to differences in cooking times. If your potatoes are still hard, simply continue cooking the casserole on LOW for an additional 30-60 minutes, or until they are fork-tender. Make sure there’s enough liquid in the slow cooker; if it looks dry, you can add a splash of milk or water. Always test a few pieces of potato from different areas of the casserole to ensure overall doneness before serving.

Can I use fresh potatoes instead of boxed mixes?

While this recipe is designed for the convenience of boxed scalloped or au gratin potato mixes, you can adapt it for fresh potatoes. You would need about 4-5 medium potatoes (like Russet or Yukon Gold), peeled and very thinly sliced (about 1/8-inch thick). You would also need to create a homemade cheese sauce to replace the seasoning packets and some of the liquid. This would significantly increase prep time and change the flavor profile, so it essentially becomes a different recipe. For this specific “slow cooker cheesy ham and scalloped potato casserole” recipe, the boxed mixes are key to its ease and texture.

What kind of ham is best for this recipe?

For convenience, pre-diced cooked ham (canned or vacuum-sealed) works wonderfully. It’s already cooked and seasoned, making prep a breeze. If you have leftover ham from a holiday roast, that’s an excellent choice too – just dice it into bite-sized pieces. Smoked ham or even a good quality deli ham cut into cubes would also be delicious. Avoid raw ham, and ensure whatever ham you use is fully cooked before adding it to the slow cooker.
