Ingredients

(Yields approximately 6-8 servings for a 6-quart slow cooker)

• 2.5 lbs (about 1.1 kg) Russet or Yukon Gold potatoes, peeled and thinly sliced (about 1/8 inch / 3 mm thick)
• 2 cups (about 340 g) cooked ham, diced into 1/2-inch (1.2 cm) cubes
• 1 small onion, finely diced (about 1/2 cup / 80 g)
• 2 cloves garlic, minced
• 1/4 cup (30 g) all-purpose flour
• 1.5 cups (360 ml) whole milk
• 1 cup (240 ml) chicken broth or vegetable broth
• 1/2 cup (120 ml) heavy cream
• 1.5 cups (150 g) shredded sharp cheddar cheese, divided
• 1/2 cup (50 g) shredded Gruyere cheese (or additional cheddar), divided
• 1 tsp salt
• 1/2 tsp black pepper
• 1/2 tsp smoked paprika
• Fresh parsley, chopped, for garnish (optional)

Ingredient Notes

• Potatoes: Russet potatoes are classic for scalloped dishes as they soften beautifully and absorb flavor well. Yukon Gold potatoes also work great and offer a slightly creamier texture. Aim for uniform 1/8-inch slices for even cooking. A mandoline slicer makes this quick and easy.
• Ham: Use pre-cooked ham, such as leftover holiday ham, a ham steak, or store-bought diced ham. Avoid raw ham, as it will not cook properly and may release too much liquid.
• Cheese: Sharp cheddar and Gruyere provide a fantastic flavor combination and melt smoothly. Feel free to experiment with other good melting cheeses like Monterey Jack, Fontina, or Colby.
• Liquid Base: The combination of milk, broth, and heavy cream creates a rich, flavorful, and creamy sauce. For a lighter version, you can reduce the heavy cream and use more milk or broth, but the richness will be slightly less intense.

Equipment You’ll Need

• 6-quart slow cooker
• Mandoline slicer or sharp chef’s knife
• Large mixing bowl
• Whisk

How to Make Easy Slow Cooker Scalloped Potatoes & Ham

Follow these simple steps to create a truly delicious and hands-off meal:

1. Prepare Your Ingredients

   Peel and thinly slice your potatoes to an even 1/8-inch (3 mm) thickness. Dice your cooked ham into 1/2-inch (1.2 cm) cubes, and finely dice the onion. Mince the garlic. Lightly grease the inside of your 6-quart slow cooker with cooking spray or butter to prevent sticking.

   

2. Whisk the Creamy Sauce

   In a large mixing bowl, whisk together the all-purpose flour, salt, black pepper, and smoked paprika. Gradually pour in the milk, chicken broth, and heavy cream, whisking continuously until the mixture is smooth and no lumps of flour remain. This creates the flavorful base for your scalloped potatoes.

3. Layer in the Slow Cooker

   Spread about one-third of the sliced potatoes evenly across the bottom of the prepared slow cooker. Sprinkle with half of the diced ham, half of the diced onion, and half of the minced garlic. Pour about one-third of the whisked cream sauce over this layer. Sprinkle with 1/2 cup (50 g) of the shredded cheddar cheese and 1/4 cup (25 g) of the Gruyere cheese.

   Repeat this layering process once more: another third of the potatoes, the remaining ham, onion, and garlic, another third of the sauce, and another 1/2 cup (50 g) each of cheddar and Gruyere cheese. Finish with the remaining potatoes and pour the last third of the cream sauce over the top, ensuring the potatoes are mostly submerged.

   

4. Cook Until Tender

   Cover the slow cooker and cook on the LOW setting for 4-5 hours, or on the HIGH setting for 2-3 hours, or until the potatoes are fork-tender and the sauce is bubbly and thickened. Cooking times can vary slightly depending on your slow cooker and potato thickness.

5. Add Final Cheese & Serve

   Once the potatoes are tender, carefully open the lid. Stir gently to ensure all potatoes are coated in the sauce. Sprinkle the remaining 1/2 cup (50 g) of shredded cheddar cheese over the top. Recover and cook for another 15-20 minutes, or until the cheese is melted and bubbly. If desired, garnish with fresh chopped parsley before serving hot.

Pro Tips for the Best Results

1. Uniform Potato Slices: Consistency is key! Thin, even slices ensure all potatoes cook at the same rate and become perfectly tender. A mandoline makes this task effortless.
2. Don’t Overcrowd: While this recipe uses a 6-quart slow cooker, avoid filling it to the very brim, especially if your slow cooker tends to cook hotter. Leave a little room for the sauce to bubble.
3. Check for Doneness: Potatoes should be easily pierced with a fork. If they’re still firm, continue cooking for another 30-60 minutes on low.
4. Avoid Lifting the Lid Too Often: Each time you lift the lid, heat escapes, and it adds about 15-20 minutes to your cooking time. Resist the urge to peek!
5. Pre-cooked Ham is Essential: Using raw ham can introduce too much moisture and change the overall texture and cooking time of the dish.
6. Adjust Seasoning: Ham can be salty, so taste your sauce mixture before adding excessive salt. You can always add more at the end.

Common Mistakes to Avoid

• Soggy Potatoes: This usually happens from uneven potato slices (some cook faster than others) or from too much liquid. Stick to the recommended liquid amounts.
• Soupy Sauce: If your sauce is too thin, it might be due to too much liquid or not enough flour. Ensure your flour is well incorporated into the cold liquids to prevent lumps and help thicken the sauce.
• Sticking to the Bottom: Always lightly grease your slow cooker insert, especially for creamy, starchy dishes like this.
• Over-stirring: While you’ll gently stir before adding the final cheese, excessive stirring can break down the tender potatoes and make the dish mushy.

Variations & Substitutions

• Cheesy Swaps: Experiment with different cheese combinations. Smoked gouda, white cheddar, or a Mexican blend would all be delicious.
• Add Vegetables: Stir in a cup of frozen peas or corn during the last 30 minutes of cooking for extra color and nutrition. Sautéed mushrooms or bell peppers could also be added with the ham layer.
• Spice It Up: A pinch of cayenne pepper or red pepper flakes can add a subtle kick to the sauce.
• Herbaceous Twist: Fresh thyme or rosemary sprigs added to the slow cooker can infuse a wonderful aroma and flavor. Remove before serving.
• Different Proteins: While ham is classic, you could use cooked, shredded chicken or even browned crumbled sausage for a different take on the dish.

Serving Suggestions

This Easy Slow Cooker Scalloped Potatoes & Ham is a complete meal on its own, but it pairs wonderfully with simple sides that complement its richness:

• A fresh, crisp green salad with a light vinaigrette to cut through the richness.
• Steamed or roasted green beans, broccoli, or asparagus.
• Crusty bread for soaking up every last bit of that delicious sauce.
• For a heartier meal, serve alongside a simple roasted chicken or pork loin.

Storage & Reheating

• Refrigerator: Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days.
• Freezer: Freezing scalloped potatoes with a cream sauce is not ideal, as the potatoes can become mealy and the sauce may separate upon thawing. If you must freeze, thaw completely in the refrigerator before reheating.
• Reheating: For best results, reheat individual portions in the microwave until warmed through. For larger quantities, transfer to an oven-safe dish, cover with foil, and bake at 300°F (150°C) for 20-30 minutes, or until heated through. Add a splash of milk or broth if it seems dry.

FAQ

Can I use raw ham in this recipe?

No, this recipe requires cooked ham. Raw ham would not cook thoroughly or release the right flavors and textures in the same way as pre-cooked ham, and it may affect the liquid balance of the dish.

What’s the best way to slice potatoes thinly and evenly?

A mandoline slicer is your best tool for achieving perfectly thin and uniform potato slices. If you don’t have one, a very sharp chef’s knife and careful, steady hands will also work.

My potatoes are still hard after the recommended cooking time, what should I do?

Cooking times can vary based on your slow cooker model, the thickness of your potato slices, and even the potato variety. If your potatoes are still firm, simply continue cooking on low for another 30-60 minutes, checking periodically. Ensure your slow cooker lid forms a tight seal to retain heat.

Can I make this recipe ahead of time?

You can prepare the sauce mixture and slice the potatoes a day in advance. Store the potatoes submerged in cold water in the refrigerator (to prevent browning) and the sauce in a separate airtight container. Assemble and cook fresh on the day you plan to serve it.

Why is my sauce too thin/soupy?

This can happen if the flour wasn’t fully incorporated, if too much liquid was added, or if the lid was lifted too often during cooking, preventing proper thickening. Make sure to whisk the flour thoroughly into the cold liquids before adding to the slow cooker.

Is this recipe freezer-friendly?

While technically possible, scalloped potatoes with cream sauces don’t tend to freeze and thaw very well. The potatoes can become mealy, and the sauce may separate or become grainy. It’s best enjoyed fresh or from the refrigerator within a few days.
