Spinach Feta Sun Dried Tomato Cups

The smell of spinach hitting a hot skillet at six in the morning is oddly comforting, like the kitchen is already awake before you are. These little egg muffin cups came out of a chaotic Tuesday when I needed something portable and found a half empty tub of feta staring back from the fridge. They have since become the most reliable thing in my weekly rotation, disappearing from the container faster than anything else I meal prep.

My neighbor Lisa once knocked on my door holding a plate of cookies around the time I had a fresh batch cooling on the counter, and we ended up trading half the cookies for four muffin cups. She texted me the recipe the same afternoon, which I thought was bold since I had just invented it in my kitchen that morning.

Ingredients

• 2 cups fresh spinach, chopped: Fresh is key here because frozen releases too much water and makes the cups soggy at the bottom.
• 1/2 cup sun dried tomatoes packed in oil, drained and finely chopped: The oil packed variety has a richer, deeper flavor than the dry ones and chops more evenly.
• 1 cup feta cheese, crumbled: Use block feta and crumble it yourself for the best texture since pre crumbled tends to be dry.
• 1/4 cup milk: Dairy or non dairy both work, and a splash of cream makes them slightly more luxurious.
• 8 large eggs: Room temperature eggs blend more smoothly into the mixture and produce a lighter texture.
• 1/2 teaspoon salt: Feta is already salty so taste your batter before adding more.
• 1/4 teaspoon black pepper: Freshly cracked makes a noticeable difference in such a simple recipe.
• 1/4 teaspoon dried oregano: Optional but it ties the Mediterranean flavors together beautifully.
• 1 tablespoon olive oil: Just enough to wilt the spinach and add a subtle fruity note.

Instructions

Prepare the oven and tin:

Preheat your oven to 350 degrees F and grease a 12 cup muffin tin generously or line it with silicone cups for the easiest removal.

Wilt the spinach:

Warm the olive oil in a skillet over medium heat and toss in the chopped spinach, stirring until it collapses into a dark green pile, about 2 to 3 minutes, then set it aside to cool.

Whisk the base:

Crack all eight eggs into a large bowl, pour in the milk, and add salt, pepper, and oregano, whisking until the yolks disappear and everything looks uniform.

Fold in the fillings:

Gently stir the cooled spinach, chopped sun dried tomatoes, and crumbled feta into the egg mixture until evenly distributed without overmixing.

Fill the cups:

Divide the mixture among the muffin cups, filling each about three quarters full to leave room for puffing without overflowing.

Bake until set:

Slide the tin into the oven and bake for 18 to 22 minutes, watching for slightly golden tops and centers that spring back when touched.

Cool and serve:

Let them rest in the tin for 5 minutes before gently loosening the edges with a butter knife and lifting them out to serve warm or at room temperature.

Save

There is something about pulling a tray of these golden cups from the oven that makes a random Wednesday feel like you have your life together.

Storing and Reheating

Let the muffin cups cool completely before transferring them to an airtight container in the refrigerator, where they stay good for up to four days. Reheat one or two at a time in the microwave for about 30 seconds, or eat them cold straight from the fridge if you are running late and do not care about temperature anymore.

Swaps and Variations

Goat cheese melts into the eggs differently than feta and creates a creamier center, which some people actually prefer. Chopped fresh basil or parsley stirred in at the last minute brightens everything up, and a pinch of red pepper flakes gives them a quiet heat that builds with each bite.

Getting the Texture Right

Silicone muffin liners are the single best investment for this recipe because nothing sticks and you never have to scrub baked egg off metal again. The cups will puff up dramatically in the oven and then sink slightly as they cool, which is completely normal and not a sign you did anything wrong.

• Let them cool in the tin for the full five minutes or they may collapse when you try to remove them too soon.
• A toothpick inserted in the center should come out clean when they are done.
• Always grease the tin even if you think it is nonstick because egg is stubborn and will find a way to stick.

Save

Keep a batch in the fridge and your future self will thank you on those mornings when cooking feels impossible but eating well still matters.

Recipe FAQs

→ Can I make these egg muffin cups ahead of time?

Absolutely. These Mediterranean-style cups store exceptionally well in an airtight container for up to 4 days in the refrigerator. They reheat beautifully in the microwave for 30-45 seconds, making them perfect for batch cooking and grab-and-go breakfasts throughout the week.

→ What's the best way to prevent sticking?

Lightly grease your muffin tin thoroughly with olive oil or butter, or use silicone muffin cups for easy release. Letting them cool in the tin for 5 minutes after baking also helps them set properly before removing, ensuring they come out cleanly without breaking apart.

→ Can I use frozen spinach instead of fresh?

Yes, frozen spinach works well if thoroughly thawed and squeezed to remove excess moisture. Use about 10 ounces frozen spinach (equivalent to 2 cups fresh chopped) and press it firmly in a sieve or colander to prevent the mixture from becoming watery during baking.

→ What can I substitute for feta cheese?

Goat cheese offers a similar creamy tang and works wonderfully as a direct substitute. For a dairy-free option, try crumbled firm tofu seasoned with nutritional yeast and lemon juice, or omit entirely and increase the sun-dried tomatoes for extra flavor intensity.

→ How do I know when the egg muffins are done baking?

The muffins are ready when they're set in the center—no liquid egg should remain when gently jiggled—and the tops are lightly golden. A toothpick inserted into the center should come out clean. They'll continue cooking slightly as they cool, so remove them while they still look slightly moist on top.
