Ingredient Notes
Boneless, skinless chicken breasts are what you want here. If yours are enormous, like the kind that look as if they came from a chicken with a gym membership, slice them horizontally so they cook more evenly. Smaller breasts can stay whole.
For the ham, use thin deli ham—nothing fancy, just a good basic package from the grocery store. Lower-sodium ham is a good option because the soup and cheese bring plenty of salt already. But regular ham is perfectly fine. This is not a recipe that requires a special trip across town, thank heavens.
Swiss cheese is the classic choice and has that mild, nutty flavor that makes this taste like actual chicken cordon bleu. Provolone works too, especially if Swiss is not a favorite.
Cream of chicken soup makes the easy creamy sauce. Yes, it comes from a can. There is no need to make a béchamel. Milk thins it enough to pour over the layers and keeps the whole thing from becoming too gloppy. That is a technical culinary term.
Ingredients
- 4 boneless, skinless chicken breasts
- 4 to 6 slices thin deli ham, enough to cover the chicken
- 4 to 6 slices Swiss cheese, or provolone if that’s what your people will eat
- 1 (10.5-ounce) can cream of chicken soup
- 1/2 cup milk
- Nonstick cooking spray for the slow cooker
- Salt and pepper, for the table if needed—I usually wait because ham and Swiss can be salty enough already
Instructions
Lightly spray the inside of your slow cooker with nonstick cooking spray. Do not skip this if you value an easy cleanup. Life is short and dish soap is not a character-building activity.
Arrange the 4 chicken breasts in a single layer across the bottom of the slow cooker. If they are very thick, slice them in half horizontally first so they cook more evenly. You do not need to pound them or roll them up or perform any kind of poultry origami.
Lay 4 to 6 slices of thin deli ham over the chicken, folding or tearing the slices as needed so each breast gets covered. It does not have to look perfect. Once it cooks, nobody can tell whether you arranged it with care or not.
Place 4 to 6 slices of Swiss cheese over the ham, making sure each piece of chicken gets a nice blanket of cheese. If you are using provolone instead, go right ahead. It melts beautifully and is a little gentler, flavor-wise.
In a small bowl, whisk together the can of cream of chicken soup and 1/2 cup milk until mostly smooth. A few tiny lumps are not the end of civilization. Pour the mixture evenly over the chicken, ham, and cheese.
Cover the slow cooker and cook on LOW for 4 to 5 hours or on HIGH for 2 to 3 hours, until the chicken is tender and cooked through to 165°F in the thickest part. Try not to lift the lid every half hour out of curiosity. Each peek lets out heat and slows things down.
Carefully remove the chicken with a wide spatula or large spoon, making sure to scoop up the ham, melted cheese, and some of that creamy sauce with each serving. The layers may slide around a little. Serve hot over mashed potatoes, egg noodles, or rice, then taste the sauce at the table before adding salt and pepper.
Variations
Mozzarella is another mild option if you have picky eaters, though it turns the dish into more of a creamy ham-and-cheese chicken situation than traditional cordon bleu. Still good. Nobody is handing out medals.
If you want a little extra zip, stir a teaspoon of Dijon mustard into the soup and milk before pouring it over the chicken. It gives the sauce that old-school cordon bleu flavor without making it taste like a mustard sandwich. Use the teaspoon.
For a crunchy topping, toast crushed butter crackers or seasoned breadcrumbs in a skillet with a little butter while the chicken finishes cooking, then scatter them over each serving right before it goes to the table. Do not put them in the slow cooker at the beginning. They will turn into a soft, mysterious paste.
You can also tuck in a handful of frozen peas or add baby spinach during the last 30 minutes.
Storage & Reheating
Leftovers keep well in a covered container in the refrigerator for up to 3 days. Store the chicken with plenty of sauce, because that sauce helps keep everything from drying out. The ham and cheese may not look quite as tidy the next day, but everything will still reheat well.
Reheat individual portions gently in the microwave, covered loosely, until hot. Add a spoonful of milk if the sauce has thickened up too much overnight. You can also warm it in a covered skillet over low heat, but keep an eye on it; chicken breast goes from tender to sad in a hurry if you bully it with high heat.
Freezing is not ideal because creamy canned-soup sauces can separate a bit after thawing. Not inedible, just a little odd-looking.
Final Notes
This is the sort of dinner that makes the house smell like somebody took care of things, even if the mail is piled up by the door and there are three cups in the living room for reasons nobody can explain. There is comfort in that.
Just serve it with something to catch the sauce, don’t over-salt it before you taste it, and let the slow cooker handle the fancy part.
