Preparing Spinach Feta Breakfast Casserole
Creating a Spinach Feta Breakfast Casserole is a delightful way to kickstart your morning. With layers of flavor and wholesome ingredients, this dish can easily become a weekly staple. Let’s walk through the preparation steps together!
Gather and prepare the ingredients
Before diving into cooking, organization is key. Collect the following ingredients:
- ½ of a 28 oz. bag of frozen Potatoes O'Brien
- 1 tablespoon of olive oil
- 5 ounces of fresh baby spinach
- 10 eggs
- 1.5 cups of whole milk
- Seasonings: ¼ teaspoon garlic powder, ¼ teaspoon onion powder, ¼ teaspoon dried thyme, dash of white pepper, salt, and black pepper to taste
- 3 tablespoons of sliced scallions
- 1.5 cups of feta cheese crumbles
- Optional: crushed red pepper flakes for some heat, along with chives and hot sauce for garnishing
Having everything laid out not only streamlines your cooking process but also adds to the pleasure of food preparation.
Cook the Potatoes O'Brien
To achieve that crispy base, start by cooking the Potatoes O'Brien. In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the frozen potatoes and let them cook for about 10-15 minutes until they are tender and golden brown. This step will establish a hearty foundation for your casserole.
Sauté the fresh spinach
Once the potatoes are ready, it’s time to enhance the flavor profile of your casserole with fresh spinach. In the same skillet (after removing the potatoes), add a drizzle more of olive oil if necessary, and toss in the spinach. Sauté it for about 3-5 minutes until just wilted. Not only does fresh spinach offer an impressive array of vitamins, but it also contributes a vibrant color and unique taste to your dish.
Make the egg mixture
In a large mixing bowl, whisk together the eggs, whole milk, garlic powder, onion powder, thyme, and both salts and peppers. This will be the custard-like base that binds everything together. The combination of milk and eggs adds a rich creaminess that elevates the casserole’s texture.
Assemble the casserole
Now, it’s time to put everything together! Spray a 9x13 baking dish with cooking spray. Spread the cooked Potatoes O'Brien across the bottom, followed by the sautéed spinach. Pour the egg mixture over the top, carefully ensuring an even distribution. Finally, sprinkle the feta cheese crumbles throughout. Each bite will be a blissful blend of flavors!
Bake to perfection
Preheat your oven to 350°F (175°C) and bake the casserole for 40 minutes, or until the eggs are fully set. When the edges begin to brown slightly, you’ll know it’s ready! Let it rest for a few minutes, then garnish with your choice of chives or hot sauce before diving in. This Spinach Feta Breakfast Casserole not only looks impressive but also fills your home with a delicious aroma—perfect for impressing guests or enjoying a cozy morning at home!

Variations on Spinach Feta Breakfast Casserole
Mediterranean Twist with Sun-Dried Tomatoes
Why not give your Spinach Feta Breakfast Casserole a delightful Mediterranean flair? By adding chopped sun-dried tomatoes, you can enhance the flavor profile and add a burst of color. These tangy gems infuse the dish with richness and complement the feta beautifully. Just mix in about half a cup before baking, and you’ll be surprised at how a small change can make a big difference!
Adding Protein Options like Turkey Bacon or Chicken Ham
For those who crave a bit of protein, consider incorporating turkey bacon or chicken ham into your Spinach Feta Breakfast Casserole. Both options bring a savory depth that balances the dish well. Simply cook and crumble the turkey bacon or chicken ham before layering it in the baking dish. Not only does this add satisfying texture, but it also makes your breakfast even more filling, perfect for fueling your busy mornings.
Cooking tips and notes for Spinach Feta Breakfast Casserole
Finding the right bake time
Getting the perfect bake time for your Spinach Feta Breakfast Casserole is essential for ensuring a delightful texture. Start checking around the 35-minute mark; the casserole is done when the egg mixture is set and no longer jiggly in the middle. Every oven is different, so don’t hesitate to adjust the time slightly! If you find that the top is browning too quickly, a sheet of foil can help prevent over-browning while the center finishes cooking.
Substitutions for dietary restrictions
If you have dietary restrictions, worry not! The Spinach Feta Breakfast Casserole is highly versatile. For a gluten-free option, you can swap frozen Potatoes O'Brien for fresh potatoes or use gluten-free hash browns. For dairy-free eaters, simply replace the whole milk with almond or oat milk and use a plant-based feta. Additionally, feel free to experiment with egg substitutes, such as aquafaba, if you're looking for a vegan alternative. Your breakfast casserole is sure to be a hit with these adjustments!
