Keto Chicken Cordon Bleu Casserole Recipe

Living in the Dominican Republic with two teens still at home means dinner needs to hit the trifecta: hearty, healthy, and easy. This Keto Chicken Cordon Bleu Casserole checks every box. It’s a recipe I turn to when we need something warm and comforting that still works with my type 2 diabetes. With food imports being hit or miss, I’ve adapted this to work with what we have—using local queso suizo instead of Swiss and sometimes baking it in our toaster oven during power outages. It’s a dish that brings the whole family to the table with smiles and full plates.

Imagine tender chicken pieces layered with savory ham and topped with gooey melted cheese, all baked to perfection. This casserole is not just another keto recipe; it’s a delightful twist on the traditional cordon bleu, making it a family favorite that satisfies both taste buds and dietary needs.

This casserole quickly became our Sunday evening go-to. After church, when we’re all worn out and hungry, I prep it during breakfast and pop it in the oven later. No stress, all comfort.

Layered Comfort: The Essence of Cordon Bleu

This casserole brings together the comforting tastes of traditional cordon bleu in a keto-friendly format.

Rich layers of juicy chicken and savory ham are enveloped in gooey melted Swiss cheese, creating a satisfying meal that doesn’t compromise on flavor.

When we couldn’t get Swiss cheese, I used a blend of queso de freír and a little provolone. It changed the flavor slightly but kept the gooey, melty top that makes this dish irresistible.

With its creamy sauce and golden brown top, it’s the perfect centerpiece for a cozy family dinner.

I first made this when I had leftover roasted chicken and a half pack of jamón de pierna from the corner colmado. It came together so quickly, and my youngest declared it better than pizza night.

The Perfect Combination of Ingredients

At the heart of this dish lies a blend of carefully selected ingredients that work harmoniously together.

Tender chicken, which can be shredded or diced, serves as the backbone of the casserole, while the smoky ham adds a depth of flavor that enhances each bite.

Topped with two cups of shredded Swiss cheese, this dish promises a cheesy experience that will leave everyone wanting more.

Creating the Creamy Sauce

The sauce is what elevates this casserole to a new level of deliciousness.

A mix of heavy cream and chicken broth creates a rich base, while eggs provide structure and creaminess.

Seasoned with garlic powder, onion powder, and a hint of Dijon mustard, the sauce not only binds the ingredients together but also infuses the entire dish with flavor.

The Dijon mustard adds a surprising tang. I once forgot it, and the whole dish tasted flatter. Now I double-check that little yellow jar before I start.

Assembly: Layering for Success

Putting together this casserole is a simple yet rewarding process.

Start by laying down the cooked chicken and diced ham in a greased casserole dish, ensuring even coverage for maximum flavor in every bite.

Next, pour the creamy sauce over the top, followed by a generous sprinkle of Swiss cheese to finish it off. This layering technique is key to achieving that gooey, cheesy top that everyone loves.

Cooking to Perfection

Baking the casserole allows the flavors to meld beautifully while achieving the perfect texture.

As it cooks, the cheese melts and turns a beautiful golden brown, while the sauce bubbles enticingly.

After about 30-35 minutes in the oven, the aroma wafting through your kitchen will surely make it hard to wait!

My kids hover when this is baking, opening the oven door just to take a peek. I tell them it needs to be bubbly and golden before it’s ready—no shortcuts!

A Warm and Inviting Presentation

Once out of the oven, allowing the casserole to rest for a few minutes enhances its ability to hold together when served.

Garnish with fresh chopped parsley for a pop of color and freshness that complements the dish beautifully.

Plated in a rustic casserole dish, this keto chicken cordon bleu casserole not only tastes amazing but also looks inviting enough to impress family and guests alike.

• Total Time: 45 minutes

Pro Tips

1. Use rotisserie chicken to save time and boost flavor.
2. Warm the cream sauce slightly before pouring—it helps everything cook evenly.
3. Cover with foil for the first 20 minutes to prevent the cheese from browning too fast.
4. Let the casserole rest for 10 minutes before cutting to avoid a runny mess.
5. Add a sprinkle of nutmeg or paprika to the top before baking for extra depth.

Ingredient Substitutions:

• Use provolone or mozzarella instead of Swiss if you prefer a milder cheese.
• Swap cooked turkey for chicken—great for holiday leftovers.
• Replace heavy cream with full-fat coconut milk for a dairy-free version.
• Add steamed broccoli or cauliflower rice between layers for extra veggies.
• Use Greek yogurt (1/4 cup) in place of one egg if you’re out of eggs.

Tip from Grammie Shirley:

If you’re making this ahead of time, layer everything except the sauce and cheese. Keep those separate until just before baking so your casserole doesn’t get soggy.

Q: Can I freeze this casserole?

A: Yes! Assemble, wrap tightly, and freeze unbaked. Thaw overnight and bake as directed.
