Tips

Pan Selection: A well-seasoned cast iron skillet is ideal, but any oven-safe pan works. No oven-safe handle? Wrap in foil.

Chicken Options: Use rotisserie chicken to save time, or substitute with cooked Italian sausage for extra flavor.

Mushroom Technique: Don't overcrowd mushrooms or they'll steam. Cook in batches if needed for proper browning.

Egg Consistency: Frittata should be creamy, not dry. Remove from oven while center still jiggles slightly - it continues cooking from residual heat.

Cheese Variations: Try goat cheese, fontina, or sharp cheddar. Add fresh mozzarella for extra creaminess.

Make-Ahead: Cook vegetables and chicken the night before. Morning of, just add eggs and bake.

Serving Temperature: Delicious hot, warm, or at room temperature, making it perfect for entertaining.

Storage: Refrigerate leftovers up to 3 days. Reheat gently in microwave or enjoy cold in sandwiches.
