Professional secrets

• Use butter and olive oil together for a balanced, glossy finish.
• Deglaze the pan with a splash of broth to capture all the browned bits.
• Cover with foil halfway through baking to prevent over‑browning.

Common mistakes to avoid

• Skipping the low‑heat caramelization results in bland onions.
• Adding too much broth makes the casserole soupy.
• Over‑baking can dry out the chicken.

Substitutions

• Chicken breast: Turkey breast or firm tofu. Adjust cooking time for tofu – press well first.
• Parmesan cheese: Nutritional yeast. Provides a cheesy flavor while keeping it dairy‑free.

Variations

• Spicy Version: Add a pinch of cayenne and a drizzle of sriracha for a gentle heat.
• Mediterranean Style: Stir in chopped olives, sun‑dried tomatoes, and feta before baking.

Storage

Store leftovers in an airtight container in the refrigerator for up to three days; reheat gently on the stovetop with a splash of broth.

Make ahead

You can dice the chicken and slice the onions up to a day ahead; store them separately in the refrigerator.

Leftovers

Reheat gently in a skillet with a splash of broth, stirring until warmed through.
