This casserole takes inspiration from traditional Chicken Cordon Bleu but eliminates the tedious pounding, rolling, and breading steps. Instead, we've deconstructed those classic flavors into a layered dish that's both easier to prepare and more suitable for a ketogenic lifestyle. The almond flour topping provides just enough texture to mimic the traditional breadcrumb coating, while the creamy sauce ties everything together into a cohesive, indulgent experience.

• 4 cups cooked chicken breast, cubed or shredded
• 6 oz ham, diced
• 8 oz Swiss cheese, shredded (divided)
• 4 oz cream cheese, softened
• 1/2 cup heavy cream
• 1/4 cup grated Parmesan cheese
• 2 tbsp Dijon mustard
• 1/2 tsp garlic powder
• 1/2 tsp onion powder
• 1/2 tsp black pepper
• 1/4 tsp salt
• 2 tbsp almond flour
• 1 tbsp melted butter
• 1 tbsp chopped fresh parsley (optional)

Prepare the oven and dish

Preheat oven to 375°F (190°C). Lightly grease a 9x13-inch casserole dish.

Create the base layer

In a large bowl, combine cooked chicken, diced ham, and half of the shredded Swiss cheese. Spread mixture evenly in the prepared casserole dish.

Make the sauce

In a medium bowl, whisk together cream cheese, heavy cream, Dijon mustard, garlic powder, onion powder, black pepper, and salt until smooth.

Assemble the casserole

Pour the sauce evenly over the chicken and ham. Sprinkle with the remaining Swiss cheese and Parmesan cheese.

Prepare the topping

In a small bowl, mix almond flour and melted butter. Sprinkle over the top of the casserole.

Bake to perfection

Bake uncovered for 25–30 minutes, or until bubbly and golden brown.

Finish and serve

Garnish with chopped parsley, if desired. Serve hot.

The key to this casserole's rich flavor lies in properly layering the ingredients. Start with evenly distributing the chicken and ham mixture, ensuring there are no empty spots in your baking dish. When preparing the cream sauce, make sure your cream cheese is properly softened to avoid lumps—room temperature works best. If needed, microwave it for 15-20 seconds to soften. Whisk vigorously until the sauce is completely smooth before pouring over the meat layer.

This versatile recipe can be adapted in several ways while keeping it keto-friendly. For a more pronounced flavor, substitute Gruyère for the Swiss cheese—it adds a deeper, nuttier taste profile. If you prefer a different protein, turkey works wonderfully in place of chicken. To add more vegetables, consider mixing in 1 cup of steamed, well-drained spinach or 1/2 cup of diced roasted red peppers to the chicken mixture. For a spicier version, add 1/4 teaspoon of cayenne pepper to the sauce.

This hearty casserole pairs perfectly with simple keto-friendly sides. Serve alongside roasted broccoli or asparagus spears for added fiber and nutrients. A crisp garden salad with a high-fat dressing complements the creaminess of the dish beautifully. For a complete meal that will impress dinner guests, present the casserole in a rustic serving dish alongside a bowl of zucchini noodles or cauliflower rice to soak up the delicious sauce.

Recipe FAQs

→ Can I make this ahead of time?

Yes, assemble the entire casserole up to 24 hours in advance and refrigerate. Add 5-10 minutes to the baking time if baking straight from the refrigerator.

→ What can I use instead of almond flour?

Pork panko, crushed pork rinds, or grated Parmesan mixed with melted butter work well as low-carb alternatives for the crispy topping.

→ Is this freezer-friendly?

Absolutely. Wrap the unbaked casserole tightly and freeze for up to 3 months. Thaw overnight in the refrigerator before baking as directed.

→ Can I use uncooked chicken?

You'll need to cook the chicken first—cubed breasts typically take 10-12 minutes sautéed until cooked through, or use poached/rotisserie chicken for convenience.

→ How do I get the topping extra crispy?

Broil for 2-3 minutes at the very end of cooking, watching closely to prevent burning. The almond flour browns beautifully for extra crunch.
