Heat 1 tablespoon oil in a large skillet over medium heat until shimmering. Add chopped onion; cook, stirring occasionally, until softened and translucent, about 3 minutes.

Transfer ½ cup of the spinach mixture to a medium bowl. Add softened cream cheese, ¾ cup feta, ¼ teaspoon pepper and the remaining 1 tablespoon oil; stir with a rubber spatula until smooth and evenly combined.

In a large bowl, whisk 12 eggs, 1 cup half-and-half, the remaining spinach mixture and ¼ teaspoon each salt, pepper, crushed red pepper and black pepper until combined.

Pour the egg mixture into the prepared baking dish. Spread the cream cheese mixture over cut sides of 6 English muffin halves (about ¼ cup each); nestle them, cut-sides down, in the egg mixture, forming 2 rows of 3 muffins. Cover the dish tightly with foil.
