Tips & Tricks for the Perfect Bake

Bakeware matters: A glass dish gives even browning, while ceramic keeps heat longer for serving.
Meal prep hack: Cook, cool, and portion into containers. Lasts 3–4 days in the fridge.

Substitutions & Variations

Keto-friendly swaps: Use chicken thighs for extra fat and flavor.
Dairy-free option: Replace cream with coconut cream, use vegan mozzarella.
Vegetable swaps: Try kale, zucchini, or broccoli if spinach isn’t your favorite.
Leftover hack: Use pre-cooked chicken. reduce bake time to ~20 minutes just to heat through.
