Cheesy Chicken Cordon Bleu Bake

ADVERTISEMENT
Chicken Cordon Bleu may have French roots, but it found its real fame in American supper clubs and home kitchens in the mid‑20th century. Traditionally, it’s a rolled, breaded chicken breast stuffed with ham and Swiss, then fried or baked—a little fussy and heavy on carbs. This casserole version keeps the spirit of the original (salty ham, nutty Swiss, juicy chicken, and creamy sauce) but streamlines the technique. No pounding, rolling, or breading—just layers baked together into a rich, weeknight‑friendly dish that feels company‑worthy while staying low carb.

Because it’s so hearty, I like to balance the plate with lighter sides: buttered green beans almondine, roasted asparagus with lemon, or a crisp salad with mustard vinaigrette. For mixed crowds, you can add a starch like egg noodles, roasted potatoes, or wild rice. A dry white wine—Sauvignon Blanc or unoaked Chardonnay—pairs beautifully with the Swiss cheese and ham.
