Ingredients

2½ pounds chicken breasts (bone‑in or boneless)

½ cup mayonnaise

2 cloves garlic, minced

1 packet onion soup mix or ½ cup caramelized onions

½ cup shredded Parmesan cheese

½ cup breadcrumbs (panko or regular)

Salt and pepper, to taste

Fresh thyme or parsley (optional, for garnish)

Instructions

Preheat oven to 375°F (190°C). Lightly grease a 9×13‑inch baking dish.

Arrange chicken breasts in the dish; season with salt and pepper.

In a small bowl, mix mayonnaise, garlic, and half of the onion soup mix (or caramelized onions).

Spread the mayo mixture evenly over the chicken breasts.

In another bowl, combine breadcrumbs, Parmesan, and the remaining onion mix.

Sprinkle breadcrumb mixture over chicken, pressing gently to adhere.

Bake uncovered for 30–40 minutes, until chicken reaches 165°F (74°C) and topping is golden brown.

Garnish with fresh thyme or parsley before serving.

Notes

Swap in boneless thighs for extra juiciness.

Add a layer of caramelized onions under the chicken for more depth.

Mix Dijon mustard into the mayo for a tangy upgrade.

Use Gruyère or Swiss cheese instead of Parmesan for a more traditional French onion profile.

Add a splash of white wine to the pan before baking for extra flavor.
