Preheat the ovenPreheat your oven to 375°F (190°C). Line a 9 x13 baking sheet with parchment paper and lightly grease or spray it with olive oil.
Make the batterIn a large bowl, whisk the eggs until smooth. Add the Parmesan cheese, flour, parsley, baking powder, salt, and black pepper. Mix until a thick, uniform batter forms.
Spread the mixturePour the batter onto the prepared 9 x13 baking sheet and spread it into an even layer, about ½ inch thick. Use a spatula to smooth the top.
BakeBake for 20–25 minutes, or until the top is firm, lightly golden, and set in the center.
Cut into croutonsRemove from the oven and let cool for 5 minutes. Transfer to a cutting board and cut into small cubes or “little bites,” depending on how your mama made them.
Optional crispingFor extra crisp croutons, return the cut pieces to the baking sheet and bake for 5–7 more minutes.
ServeEnjoy in soups, salads, or straight from the tray — classic, simple, and comforting.
