There is something undeniably chaotic about Sunday mornings in my house. Between hunting for missing soccer cleats and brewing that second cup of coffee, the idea of standing over a stove flipping individual omelets for everyone feels like a marathon I didn’t sign up for. That’s exactly how this recipe was born.
I wanted the creamy, salty richness of my favorite Greek diner omelet—stuffed with spinach and feta—but I needed it in a format that let me actually sit down with my family. This spinach feta breakfast bake is my answer to the “short order cook” syndrome. It captures all those vibrant Mediterranean flavors in a single dish that slides right out of the oven, golden and bubbling.
Why This Mediterranean Breakfast Casserole Shines
What I love most about this dish is how it transforms humble ingredients into something that feels indulgent. We are using whole-wheat English muffins as the base, but instead of just toasting them, we press them into a savory custard. They soak up the egg mixture on the bottom while getting crispy on the edges, creating a texture that reminds me of a savory bread pudding.
The flavor profile is robust. By sautéing sun-dried tomatoes and garlic with the spinach first, we build a depth of flavor that raw veggies just can’t provide. And let’s be honest, feta cheese makes everything better. It adds that signature tang that cuts through the richness of the eggs.
This is also the ultimate easy make ahead spinach feta bake. You can assemble the entire thing on a Tuesday night, pop it in the fridge, and bake it Wednesday morning while you’re getting ready for work. It’s a lifesaver for busy weeks.
Balancing Your Morning Fuel
When I’m developing recipes, I’m always thinking about how the meal will make me feel two hours later. Many sweet breakfast casseroles leave me crashing by mid-morning, but this savory version is different. It is packed with high-quality protein from the eggs and cheese, and fiber from the spinach and whole grains.
For those of us mindful of our intake, this dish aligns beautifully with balanced eating principles. The combination of protein and fat helps slow down digestion, which can support steadier energy levels compared to a bagel or pastry. I often recommend pairing a slice of this with some fresh berries or a side salad to round out the meal.

How to Make Spinach Feta Breakfast Casserole
The secret to the creamy texture here is a little technique I call “the smear.” Instead of just crumbling cheese on top, we mix softened cream cheese with the sautéed spinach and feta to create a thick, savory paste. Spreading this directly onto the English muffins ensures that every single bite has a pocket of creamy goodness.
Here is a quick look at the prep flow:
- Sauté the Veggies: Getting the moisture out of the frozen spinach is key—nobody likes a watery casserole!
- Mix the Cheeses: Blend that warm spinach with your cream cheese.
- Layer Up: Place the muffin halves cheese-side down into the egg custard.

Serving Suggestions & Swaps
I usually serve this hot right out of the oven, but the leftovers reheat surprisingly well. A quick zap in the microwave brings the English muffins back to life. If you want to add a fresh element, top your slice with some diced avocado or a sprinkle of fresh dill.
Looking for a beverage pairing? Since this is a hearty, savory main, I love balancing it with something light and refreshing, like The 5-Minute Mediterranean Smoothie. It’s a great way to double down on those nutrient-dense greens!

Description
This hearty, savory casserole brings the flavors of a favorite Greek omelet into an easy-to-slice breakfast bake. By swapping heavy cream for milk and relying on the robust flavors of sun-dried tomatoes and garlic, this version stays rich and satisfying. It features whole grains and high-quality proteins, making it a delicious way to start the morning, and the leftovers reheat beautifully for busy weekdays.
Ingredients
The Savory Vegetable Base
- 1 (10-ounce) package frozen chopped spinach, thawed and squeezed very dry
- 1 small yellow onion, finely diced
- ½ cup sun-dried tomatoes packed in oil, drained well and chopped
- 1 tablespoon extra-virgin olive oil
- 1 tablespoon garlic, minced (fresh or jarred)
The Cheesy Layers
- 3 whole-wheat English muffins, split in half (6 halves total)
- 6 ounces reduced-fat cream cheese, softened to room temperature
- 1 cup feta cheese, crumbled (divided use)
The Egg Custard
- 12 large eggs
- 1 cup 1% or 2% milk
- ½ teaspoon ground black pepper, divided
- ¼ teaspoon salt
- ¼ teaspoon crushed red pepper flakes (optional, for a gentle kick)
- 1 pinch ground nutmeg (optional, adds depth to the spinach)
Instructions
- Prep the oven and dish: Preheat your oven to 350°F. Spray a 9×13-inch baking dish generously with nonstick cooking spray and set it aside.
- Sauté the aromatics: In a large skillet, heat the olive oil over medium heat. Toss in the diced onion and cook for about 3-4 minutes until it becomes soft and translucent. Stir in the chopped sun-dried tomatoes and minced garlic, cooking for just another 30 seconds until fragrant.
- Finish the vegetables: Add the dried spinach to the skillet. Cook while stirring frequently for 1-2 minutes to evaporate any lingering moisture. Remove the pan from the heat.
- Mix the spread: Transfer roughly ½ cup of the hot spinach mixture into a medium mixing bowl. Add the softened cream cheese, ¾ cup of the crumbled feta, and ¼ teaspoon of black pepper. Stir vigorously with a spatula until the heat from the veggies helps blend everything into a smooth, savory paste.
- Whisk the custard: In a large bowl, whisk together the eggs, milk, the remaining spinach mixture from the skillet, salt, crushed red pepper, nutmeg (if using), and the remaining ¼ teaspoon black pepper until fully combined.
- Assemble the bake: Pour the egg mixture directly into your prepared baking dish. Spread the cream cheese mixture generously over the cut sides of the 6 English muffin halves. Place the muffins, cheese-side down, into the egg mixture in the baking dish (arrange them in 2 rows of 3).
- Bake covered: Cover the dish tightly with aluminum foil. Bake for 25 minutes.
- Finish and serve: Remove the foil. Sprinkle the remaining ¼ cup of feta cheese over the top between the muffins. Return to the oven (uncovered) and bake for another 15 to 18 minutes, or until the eggs are set in the center and no longer jiggle. Let the casserole rest for 10 minutes to firm up before slicing.
Notes
- Allergy Alert: This recipe contains eggs, wheat/gluten, and dairy. For a gluten-free version, substitute with certified gluten-free English muffins (check carb counts as they may vary).
- Make-Ahead Tip: You can assemble the entire dish the night before (through Step 6), cover, and refrigerate. When ready to bake, let it sit on the counter while the oven preheats and add about 5-10 minutes to the covered baking time.
- Diabetes-Friendly Tip: This recipe offers excellent carbohydrate quality from whole grains and vegetables, providing a very low glycemic load (roughly 10% of daily net carb guidelines). Since the saturated fat and sodium levels are moderate to high due to the cheese and eggs, this dish pairs best with a day of meals that are otherwise lower in sodium and saturated fats to maintain a healthy balance.
