Ingredient Notes + Variations

This recipe uses simple ingredients that bring big flavor. It’s the easiest way to get that Chicken Cordon Bleu fix without all the extra steps.

• Chicken breasts – Boneless and skinless. Cut into bite-sized chunks so they cook evenly. You could also use boneless, skinless chicken thighs.
• Ham – Fully cooked and chopped. Go for deli ham or leftover spiral ham, whatever you have on hand.
• Swiss cheese – Shredded for easy melting. Gruyère works too if you want to be fancy.

Step 3: Layer Ham + Cheese

Layer the chopped ham over the chicken. Sprinkle 1 cup of the Swiss cheese over the ham.

Cover and cook on low for 5–6 hours or on high for 3–4 hours, or until the chicken reaches an internal temperature of 165° F.

Step 4: Finish with Breadcrumb Topping

In a small bowl, combine the bread crumbs, the remaining 1/2 cup of Swiss cheese, and melted butter. 

About 10–15 minutes before serving, sprinkle breadcrumb mixture overtop top and cover again to melt. Garnish with fresh chopped parsley, serve warm and enjoy!

Recipe Tips for Success

• Use freshly shredded cheese for the best melt.
• Don’t skip the Dijon. It makes the sauce taste way more complex.
• Keep the lid on! Lifting it slows everything down.
• Use stuffing mix instead of plain breadcrumbs for a little extra flavor.

Notes

Storage + Make Ahead

Yes, you can absolutely make this ahead. Assemble everything in the slow cooker insert the night before, pop it in the fridge, then start it the next day. Leftovers keep in an airtight container in the fridge for up to 4 days. Reheat in the microwave or oven. You can freeze it, but the texture of the sauce and cheese might change slightly. For best results, freeze before adding the breadcrumb topping.
