3. Step-by-Step Cooking Instructions & Crisping Secrets
The key to making this casserole a success is to not overmix the egg mixture and to not overbake the casserole.
I like to use a cast-iron skillet or air fryer basket to ensure even cooking and a crispy crust.
To check for doneness, insert an instant-read thermometer into the center of the casserole. If it reads 160°F (71°C), it’s done.

Step-by-Step Culinary Timeline
1. Preheat oven to 375°F (190°C). In a large bowl, whisk together eggs, cottage cheese, parsley, and basil.
2. Add chopped spinach, bell peppers, zucchini, and feta cheese to the bowl. Mix well to combine.
3. Pour the egg mixture into a greased cast-iron skillet or air fryer basket.
4. Bake for 25-30 minutes or until the casserole is set and the edges are golden brown.
5. Let it rest for 5 minutes before slicing and serving.
Meal-Prep Storage & Crispy Air-Fryer Reheating Guide
• Cool Before Sealing: Let cooked portions cool for 10 minutes before sealing in glass containers so steam never softens the crust (keeps 4 days in the fridge).
• Sauce on the Side: Store dips, drizzles, and fresh herbs separately until right before serving.
• 3-Minute Crispy Reheat: Reheat in a 380°F (193°C) air fryer or dry cast-iron skillet for 3–4 minutes to restore shatteringly crisp edges.
