• Spinach adds a fresh, nutritious touch without overpowering
• Feta cheese gives a creamy, tangy note that pairs well with eggs
• Milk keeps the egg cups moist and tender, preventing dryness

Ingredients

• 6 large eggs
• 1 cup (30 g) baby spinach, chopped
• 1/2 cup (75 g) crumbled feta cheese
• 2 tablespoons (30 ml) milk
• 2 tablespoons (15 g) chopped green onion

Ingredient Notes

Baby spinach is mild and soft, which cooks quickly in these egg cups. You can swap frozen chopped spinach if you prefer—just be sure to thaw and squeeze out excess moisture first to avoid watery cups. Feta adds a salty, tangy element that balances the eggs nicely. If you’re not a fan, goat cheese or a mild shredded cheese works well, but expect a different flavor profile. Fresh green onions brighten the dish and add a subtle oniony aroma—you can substitute with chives or shallots for a milder option. The milk helps keep the eggs fluffy and tender during baking, so don’t skip it.

Kitchen Tools Needed

• 6-cup muffin pan
• Whisk or fork for beating eggs
• Mixing bowl
• Measuring cups and spoons
• Spatula or spoon for stirring
• Oven mitts

Step-by-Step Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease a 6-cup muffin pan with cooking spray or butter to prevent sticking.

2. In a medium bowl, whisk together the 6 eggs and 2 tablespoons (30 ml) of milk until fully combined and slightly frothy. This helps create a light texture.

3. Stir in the chopped spinach, crumbled feta, and chopped green onions until evenly distributed throughout the egg mixture.

4. Pour the egg mixture evenly into the prepared muffin cups. Each cup should be about 3/4 full to allow space for the egg cups to puff up slightly as they bake.

5. Bake for 18 to 20 minutes. Around 18 minutes, start checking by gently wobbling a cup—if the centers no longer jiggle and the tops are lightly golden, they’re done. Avoid overbaking, which can make them dry or rubbery.

6. Let the egg cups cool for about 5 minutes before removing from the pan to prevent sticking and to let the texture set.

7. Serve warm, or cool completely before storing if you’re prepping ahead.

Pro Tips

• Chop spinach finely for even distribution and to avoid large leafy bites that can release excess moisture.
• Whisk the eggs vigorously for a fluffier texture.
• Use a non-stick spray or brush the muffin pan well—the feta’s salty moisture can make these stick more than usual.
• Don’t skip the cooling step; the egg cups firm up nicely and are easier to remove without breaking.
• For an extra burst of flavor, sprinkle a little black pepper or dried herbs on top before baking.

Common Mistakes

• Overfilling the muffin cups—they’ll puff and spill over in the oven. Fill no more than 3/4 full.
• Using frozen spinach without thawing and draining well, resulting in watery, soggy egg cups.
• Baking too long, which dries them out and toughens the texture.
• Not greasing the muffin pan thoroughly—these cups can stick and break apart when you try to remove them.
• Forgetting to check for doneness around 18 minutes; the centers can remain undercooked if you go straight to the max time.

Variations

• Swap green onions for diced red onions, shallots, or chives.
• Add diced sun-dried tomatoes or roasted red peppers for a sweeter, tangy twist.
• Mix in cooked and crumbled bacon, sausage, or ham for extra protein.
• Use kale or swiss chard instead of spinach for a heartier green.

Serving Suggestions

These egg cups work well warm right out of the oven, paired with a side of fresh fruit or toast. They’re also great for packing in lunchboxes or enjoying cold as a snack. A light drizzle of hot sauce or a dollop of Greek yogurt can add a nice contrast when serving.

Storage Instructions

Store leftovers in an airtight container in the refrigerator for up to 3 days. You can keep them whole or slice them for easier snacking.

Reheating Tips

Reheat individual egg cups in the microwave for about 30 to 40 seconds until warmed through. Avoid overheating as it can make eggs rubbery.
