Step‑by‑Step Instructions for Spinach Egg Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While the oven warms up, take a moment to butter a 9×13-inch baking dish thoroughly. This will ensure that your delicious spinach egg casserole doesn’t stick once it’s baked, making for a smooth serving experience later on.
Step 2: Sauté the Onion
In a large skillet set over medium heat, add a drizzle of olive oil. Once heated, toss in the diced onion and sauté it for about 4-5 minutes until it turns translucent and fragrant. This step builds a lovely flavor base for your casserole, enhancing the overall taste of the spinach egg casserole.
Step 3: Add the Garlic
Add minced garlic to the skillet with the onions, stirring continuously for about 30 seconds, just until it’s aromatic. This quick cooking enhances the flavor profile, making your spinach egg casserole irresistible. Keep an eye on it to prevent burning, which could overpower the dish.
Step 4: Incorporate the Spinach
Gradually add the chopped spinach to the skillet, stirring to combine the mixture evenly. Cook for just about 3-4 minutes, or until the spinach wilts down significantly. Season the mixture with salt and pepper, ensuring every layer of flavor enhances your spinach egg casserole.
Step 5: Mix the Eggs
In a mixing bowl, whisk together the eggs and milk until you achieve a smooth, homogenous mixture. Add a pinch of nutmeg, along with more salt and pepper to taste. This creamy egg base will bind all the ingredients in your spinach egg casserole together beautifully.
Step 6: Assemble the Casserole
Spread the sautéed spinach mixture evenly across the bottom of your prepared baking dish. Then, sprinkle your choice of cheese over the top. Finally, pour the egg mixture gently over everything, allowing it to fill in the gaps and coat the filling thoroughly, making every bite flavorful.
Step 7: Bake
Place the assembled spinach egg casserole into the preheated oven. Bake for 35-40 minutes, or until the top is golden brown and a knife inserted into the center comes out clean. This visual cue ensures your casserole is set and ready for slicing.
Step 8: Cool and Serve
After baking, let your spinach egg casserole cool for 10 minutes before slicing. This resting time allows the casserole to firm up slightly, making for cleaner, more manageable slices. Once cooled, serve warm and enjoy the delectable flavors while they last!

- Fridge: Store your spinach egg casserole tightly covered in the refrigerator for up to 4 days to maintain freshness and flavor.

Spinach Egg Casserole Recipe FAQs
How do I select the best spinach for this casserole?
Absolutely! Look for fresh spinach with vibrant green leaves and no dark spots or signs of wilting. If you’re using frozen spinach, ensure it’s fully thawed and well-drained to avoid introducing excess moisture into your casserole.
What’s the best way to store leftovers of the spinach egg casserole?
Very good question! Store your spinach egg casserole in an airtight container in the refrigerator for up to 4 days. It’s ideal to allow it to cool completely before covering to prevent condensation, which could make it soggy.

What if my casserole doesn’t set properly while baking?
Not to worry! If your spinach egg casserole is still jiggly in the center after the baking time, simply cover it loosely with foil and return it to the oven for an additional 5-10 minutes. Be sure to check with a knife in the center; it should come out clean when the casserole is fully cooked.
Are there any dietary considerations I should keep in mind?
Absolutely! If you have allergies, this spinach egg casserole can be made gluten-free by ensuring the milk and cheese options are certified gluten-free. For dairy-free alternatives, you can substitute regular milk with almond milk and cheese with nutritional yeast or dairy-free cheese. Always check ingredient labels if cooking for someone with food sensitivities.
How can I ensure my spinach egg casserole doesn’t get watery?
Very important! To prevent a watery casserole, make sure to thoroughly drain any excess moisture from the spinach before adding it to the mix.
