Made with eggs, zucchini, peppers, onion, and a sprinkle of Parmesan, this recipe reminds me of the kind of dish you’d see in a 1980s church cookbook — wholesome, flexible, and perfect for using up what’s in the fridge.

Frequently Asked Questions about Oven Skillet Fritatta
What is the difference between a frittata and an omelet?
A frittata is cooked slowly and finished in the oven, while an omelet is folded and cooked quickly on the stovetop.
Can you make a frittata ahead of time?
Yes! Frittatas reheat beautifully and are great for meal prep. Store covered in the fridge up to 4 days.
Can you freeze a frittata?
Yes. Slice into portions, wrap tightly, and freeze up to 2 months. Reheat in the oven or microwave.
Why is my frittata watery?
This usually comes from high-moisture vegetables like zucchini or tomatoes. Lightly sautéing them first prevents this.
What pan is best for a frittata?
A cast iron or oven-safe skillet is ideal so it can go from stovetop to oven.
