Sausage and Peppers Frittata
A rustic, oven-finished frittata loaded with savory Italian sausage, sweet bell peppers, and caramelized onions. Eggs are whisked with a touch of milk for a creamy, fluffy texture, then baked until golden and puffed. Perfect for brunch, lunch, or a quick weeknight dinner, this one-pan dish comes together in about 30 minutes and tastes just as good at room temperature.

Bake until puffed and just set in the center.
Transfer skillet to the preheated oven. Bake for 13-16 minutes until the edges are puffed and lightly golden, and the center is just set with a slight jiggle. The frittata will continue cooking from residual heat after you pull it.
TIPA slight wobble in the center is perfect — it finishes setting outside the oven. Overbaking makes it rubbery. - rest · ~5 min
Rest briefly before slicing.
Remove skillet from oven and let the frittata rest for 5 minutes. Run a spatula around the edge to loosen, then slide onto a cutting board or slice directly in the skillet.

What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Use a well-seasoned 10-inch cast-iron skillet for even browning and a non-stick finish.
- 2Let the eggs sit at room temperature for 10 minutes before whisking for a fluffier texture.
- 3Avoid over-whisking the eggs — just until smooth and slightly frothy to keep the frittata tender.
- 4Slide a thin spatula around the edge right after baking to prevent sticking as it cools.
- 5The frittata keeps well in the fridge for up to 3 days; reheat gently in a low oven or microwave.
- 6For cleaner slices, let the frittata rest the full 5 minutes and use a sharp, serrated knife.
