First Watch’s Frittata Rustica Recipe Tips

  • Use fresh ingredients: Fresh veggies and eggs make a noticeable difference in flavor.
  • Even chopping: Dice vegetables uniformly so they cook evenly throughout the frittata.
  • Air fryer-safe dish: Make sure your dish fits comfortably in your air fryer basket for even cooking.
  • Check doneness: Insert a toothpick in the center; it should come out clean.
  • Customize your mix-ins: Swap spinach for kale, cherry tomatoes for roasted peppers, or add cooked sausage for a heartier dish.
  • Cheese timing: Add shredded cheese in the last 2 minutes to melt without overcooking.
  • Let it rest: Allow 2–3 minutes after cooking before slicing to keep it firm and easier to serve.

Storing Instructions

  • Refrigerator: Allow the frittata to cool completely. Wrap tightly in plastic wrap or place in an airtight container. It will keep in the fridge for up to 4 days.
  • Freezer: For longer storage, wrap individual slices in plastic wrap and place them in a freezer-safe bag or container. Freeze for up to 2 months.
  • Reheating: Reheat slices in the air fryer at 325°F for 3–5 minutes, or in the microwave for 1–2 minutes until warmed through. Avoid overheating to keep it from drying out.
