Spinach Feta Breakfast Casserole Ingredients
• This flavorful dish requires simple yet delicious components to create a breakfast masterpiece!
For the Base

For Seasonings
• Garlic Powder – Elevates the overall taste; adjust according to your preference.
• Onion Powder – Complements the other flavors nicely; use sparingly for a subtle hint.

Step‑by‑Step Instructions for Spinach Feta Breakfast Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This is a crucial first step to ensure that your Spinach Feta Breakfast Casserole bakes evenly and thoroughly. While the oven heats, you can prepare your baking dish and ingredients, making the cooking process smooth and efficient.
Step 2: Prepare the Baking Dish
Spray a 9×13-inch baking dish with non-stick cooking spray. Then, layer half of the frozen Potatoes O’Brien at the bottom of the dish. This creates a hearty base that will absorb flavors and provide a delightful texture. Make sure the potatoes are evenly spread to ensure thorough cooking.
Step 3: Sauté the Spinach
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Once hot, add the fresh baby spinach and sauté for about 3-5 minutes, stirring frequently until the spinach is wilted and vibrant green. This step enhances the flavor, which is a key element of your Spinach Feta Breakfast Casserole.
Step 4: Whisk the Egg Mixture
In a mixing bowl, crack in the eggs and add 1 cup of whole milk along with your desired seasonings, including garlic powder, onion powder, dried thyme, white pepper, salt, and black pepper. Whisk everything together until the mixture is homogenous, ensuring a light and fluffy texture in your casserole.
Step 5: Assemble the Casserole
Evenly distribute the sautéed spinach over the layer of Potatoes O’Brien in the prepared baking dish. Next, pour the egg mixture over the spinach and potatoes, making sure it’s evenly coated. This will bind the ingredients together as it bakes, resulting in a cohesive Spinach Feta Breakfast Casserole.
Step 6: Add the Feta Cheese
Sprinkle the crumbled feta cheese generously over the top of the casserole. This not only adds a lovely creamy and tangy element but also enhances the overall flavor profile. Be sure to distribute the feta evenly for the best results.
Step 7: Bake the Casserole
Place the baking dish in the preheated oven and bake for about 40 minutes. Look for the eggs to be fully set, and a light golden-brown color on the top. If you’re using a glass dish, allow it to cool slightly to avoid temperature shock when serving.
Step 8: Garnish and Serve
Once baked, remove the casserole from the oven and let it sit for a few minutes. For an added touch of freshness, sprinkle with chopped chives and serve with hot sauce on the side, if desired. Enjoy your hearty and delicious Spinach Feta Breakfast Casserole, perfect for any breakfast or brunch!

Cheese Choice: Adjust the salt in the recipe based on the feta cheese’s saltiness. A milder feta can reduce the need for additional seasoning.

Spinach Feta Breakfast Casserole Recipe FAQs
What should I look for when selecting fresh spinach?
Absolutely! When choosing fresh spinach, look for vibrant green leaves that are not wilted or yellowing. Avoid any bags with dark spots all over or slimy textures. Fresh spinach should feel crisp and perform well when sautéed.
How should I store leftovers from my casserole?
Very! To store leftovers, place them in an airtight container in the refrigerator. They’ll be good for 3-4 days. Just make sure to let the casserole cool completely before storing to maintain its texture and flavor.
Can I freeze my Spinach Feta Breakfast Casserole?
Absolutely! To freeze your casserole, first allow it to cool completely. Then wrap it tightly in plastic wrap and then in aluminum foil. It can stay in the freezer for up to 3 months. When you’re ready to eat, thaw it overnight in the fridge and reheat in the oven at 350°F (175°C) for 20-25 minutes.
What if my casserole comes out watery or not set properly?
No worries! If your casserole turns out watery, it’s often because of excess moisture from either using frozen spinach that wasn’t properly drained or not letting the dish set long enough after baking. Make sure to sauté the spinach fully and allow the casserole to cool for a few minutes before serving, which helps it firm up for easier slicing.
Are there any dietary considerations for pets, allergies, or special diets?
Yes, definitely! This Spinach Feta Breakfast Casserole is vegetarian-friendly but be mindful if anyone has a dairy allergy; you can substitute feta with a dairy-free cheese. Additionally, while spinach is safe for dogs, it should be given in moderation. Always check with a vet for your pet’s specific dietary requirements.

Very much so! I often prepare this casserole the night before. Simply assemble everything in the baking dish, cover it tightly with plastic wrap, and refrigerate overnight.
