Ingredients Overview

Chicken Breasts
The foundation of the dish. Boneless, skinless chicken breasts cook up tender and juicy in the slow cooker.

Ham
Adds salty, savory depth and gives the dish its classic cordon bleu character.

Swiss Cheese
Mild, nutty, and perfectly melty—Swiss cheese brings creamy richness to every bite.

Cream Soup
Creates the luxurious sauce base. Cream of chicken works best, but mushroom is also great.

Milk
Thins the sauce just enough to keep it silky and spoonable.

Dijon Mustard
The signature flavor booster—adds subtle tang and sophistication without overpowering.

Italian Seasoning
A gentle blend of herbs that enhances the sauce and chicken.

Garlic Powder
Adds warmth and depth without overwhelming the delicate flavors.

Salt & Pepper
Essential seasonings to balance everything.

Breadcrumbs (Optional)
For that classic crispy topping reminiscent of baked cordon bleu.

Butter (Optional)
Mixed with breadcrumbs to create a golden, crunchy finish.

Step-by-Step Cooking Instructions

Step 1: Prep the Slow Cooker

Lightly grease the slow cooker with nonstick spray or butter to prevent sticking.

Step 2: Season the Chicken

Season both sides of the chicken breasts with salt, pepper, and garlic powder.

Step 3: Layer the Chicken

Place the chicken in the slow cooker in an even layer.

Step 4: Add Ham & Cheese

Top each piece of chicken with a slice of ham, followed by Swiss cheese.

Step 5: Make the Sauce

In a bowl, whisk together the cream soup, milk, Dijon mustard, and Italian seasoning until smooth.

Step 6: Pour the Sauce

Pour the sauce evenly over the chicken, making sure everything is well coated.

Step 7: Slow Cook

Cover and cook on LOW for 4–5 hours, or until the chicken is tender and cooked through.

Step 8: Optional Crunchy Topping

About 20 minutes before serving, sprinkle breadcrumbs mixed with melted butter evenly over the top.

Step 9: Finish Cooking

Cover again and continue cooking until the sauce is creamy and the topping is lightly crisped.

Step 10: Serve

Serve hot, spooning plenty of sauce over the chicken. Pair with your favorite sides.
