Pasta types: Long pasta slices most cleanly. Short pasta works but needs slightly more egg to hold together.
Sauced pasta: Leftovers with meat sauce or tomato sauce work well. Reduce added salt since the sauce already provides seasoning.
The flip: Confirm the frittata releases cleanly from all sides before flipping. Move the pan over the sink as a precaution.
Storage: Refrigerate up to 3 days. Excellent cold or at room temperature. Freezes for up to 1 month.
