My mother always insisted that the secret to perfect egg casseroles was patience during the cooling period. Following her advice of waiting 10 minutes allows proteins to set properly, resulting in beautiful slices that hold together perfectly.

Frequently Asked Questions
- → Can I prepare this egg casserole the night before?
- Absolutely! You can prepare everything up to the baking step, cover tightly with plastic wrap, and refrigerate overnight. In the morning, remove from the fridge while preheating the oven, then bake as directed, adding about 5-10 extra minutes to the cooking time.
- → Can I use frozen spinach instead of fresh?
- Yes, frozen spinach works well in this recipe. Use about 2 cups of thawed frozen spinach, but be sure to squeeze out ALL excess moisture first using a clean kitchen towel or paper towels. Otherwise, your casserole might become watery.
- → How do I know when the egg casserole is fully cooked?
- The casserole is done when the eggs are completely set and no longer jiggly in the center. A knife inserted into the middle should come out clean, and the edges will be slightly golden brown. If the top starts browning too quickly before the center is set, cover loosely with foil.
- → What can I serve with this Spinach Artichoke Egg Casserole?
- For breakfast or brunch, try serving it with fresh fruit, toast, or breakfast potatoes. For dinner, pair it with a simple green salad and crusty bread. It's quite versatile and pairs well with many side dishes.
- → Can I add other vegetables to this casserole?
- Definitely! Bell peppers, mushrooms, zucchini, or cherry tomatoes would all work beautifully. Just make sure to sauté any additional vegetables until tender before adding them to the casserole to remove excess moisture.
- → What's the best way to reheat leftovers?
- Individual portions reheat well in the microwave for 1-2 minutes. For best texture, you can also reheat in an oven at 325°F for about 10 minutes until warmed through. Avoid overheating as this can make the eggs tough.
