Watch us show you how easy it is to make this crowd-pleasing dish!
HOW TO MAKE THE MUSHROOM SAUCE
We have to say that the homemade mushroom sauce for this Slow-Cooker Ham and Potatoes au Gratin is what we think puts the dish over the top.
Start by sautéing 1 lb. of sliced mushrooms. We use good ole white button mushrooms. You will create a roux by adding flour, then build the sauce with chicken stock (or vegetable), cream, and Worcestershire sauce.
EXPERT TIP: If you are in a real pinch for time, you can use two cans of condensed cream of mushroom soup in place of the mushroom sauce. But, as mentioned, we strongly feel the homemade sauce is so much more flavorful, and it can also be made in advance.
HOW TO PREP THE INGREDIENTS
This recipe feeds a crowd, without doubt. Here’s what you’ll need on hand, and how to prep them:
- 5 to 7 large russet potatoes – We use our trusty mandolin to slice them into 1/8″ rounds, but you could certainly just slice them with a sharp knife.
- 2 12 oz. ham steaks – There are usually several varieties of ham steaks in your meat department. We go with the smoked, bone-in ham steak, and then cube the meat, cutting away excess fat and the bone.
- 1 lb. Swiss cheese – If you can’t find shredded, purchase two 8 oz. blocks and use the medium shredder with your food processor, or use a box grater to shred the cheese.
- 2 medium yellow onions – Chop them evenly with a sharp knife, or, purchase pre-chopped onion.
EXPERT TIP: Because this makes a lot, we season each layer with salt and pepper. It may seem like a lot, but remember, you’re seasoning several pounds of potatoes and ham.
HOW TO LAYER SLOW-COOKER HAM AND POTATOES AU GRATIN
If you know much about us, you know how much we love Crock-Pot. One of the amazing features of our 7qt Slow Cooker is how easy it is to clean. It’s ‘Easy Clean’ nonstick ceramic coating requires less effort to clean vs. traditional stoneware (when cleaned by hand). NICE!
Now, it’s time to start layering the ingredients.
We begin with a layer of potatoes, then cheese, ham, onions, and then salt and pepper. Repeat until you’ve reached about 1 inch from the top of the vessel.
POUR THE MUSHROOM SAUCE ON TOP OF THE CASSEROLE
Now, it’s time to top everything off with that incredible mushroom sauce!
If you made it ahead of time, no need to re-heat.
Just transfer the sauce right on top of the layered ingredients. This Slow-Cooker Ham and Potatoes au Gratin is the ultimate comfort food!
It’s now time to let our beloved Crock-Pot do its magic!
We love that the digital countdown control lets us program cook times anywhere from 30 minutes up to 20 hours.
EXPERT TIP: We almost always use the ‘LOW’ setting when cooking a dish in a slow-cooker. But honestly, this Slow-Cooker Ham and Potatoes au Gratin cooks beautifully on HIGH in just 4 hours. Of course, you can cook it on LOW for 8 to 10 hours, it’s up to you! Once the cooking time is completed, the slow-cooker automatically shifts to WARM setting to keep food at the perfect serving temperature.
