Chef John's Spinach and Feta Pie

1 . Stage

Preheat oven to 350 degrees F (175 degrees C).

2 . Stage

Heat butter in a large oven-safe skillet over high heat. Toss spinach in hot butter until wilted, about 30 seconds. Drain spinach well and squeeze it as dry as possible. Transfer to a cutting board and chop.

3 . Stage

Beat eggs in a bowl with salt, black pepper, and cayenne pepper until thoroughly combined.

4 . Stage

Place bacon in the same skillet used to cook spinach and cook over medium-high heat, stirring occasionally, until bacon has rendered its fat and is almost crisp, 5 to 8 minutes. Use a paper towel held in a tongs to remove excess bacon grease. Reduce heat to medium; saute onion with bacon and a pinch of salt until onion is translucent, about 5 more minutes.

5 . Stage

Saute chopped spinach with bacon and onion until spinach is hot; pour in eggs. Use a wooden spoon to distribute spinach evenly throughout the eggs. Sprinkle feta cheese over mixture.

6 . Stage

Bake in the preheated oven until eggs are set, 10 to 15 minutes. Top may still be a little wet.

7 . Stage

Turn on oven's broiler. Broil pie until top is lightly golden brown, 2 to 3 minutes.
