Bake a small batch of egg cups for breakfast sandwiches or a quick savory snack. Grease the muffin pan carefully and let the cups rest briefly before removing them.

Yield and time: 6 egg muffins · about 30 minutes

Spinach feta egg muffin ingredients

6 large eggs
¼ cup milk
1 cup finely chopped spinach
⅓ cup crumbled feta
¼ cup finely diced red pepper
¼ teaspoon black pepper
Oil for greasing the pan

Method

Heat oven to 350°F. Grease six standard muffin cups generously.
Whisk eggs and milk until evenly combined. Stir in spinach, feta, pepper, and red pepper.
Divide mixture among the six cups, leaving space at the top.
Bake about 18–24 minutes, until the centers reach 160°F on a food thermometer. Timing depends on the pan and oven.
Rest 5 minutes, then loosen the edges gently. Serve warm or cool promptly for storage.

Make it work for you

Use cooked, well-drained spinach in place of fresh spinach; squeeze out excess water so the cups do not become soggy. Muffin size varies, so temperature is a better doneness check than time alone. Serve two cups with toast and fruit for a breakfast idea. Contains eggs and milk. Freeze individually for easier portions, then thaw in the refrigerator and reheat to 165°F.

Storage and serving

Refrigerate perishables promptly in shallow containers. Use refrigerated leftovers within 3–4 days or freeze earlier. Reheat cooked leftovers to 165°F; keep cold meals chilled during transport. Follow ingredient labels if they require a shorter storage time.

Prepare the pan before mixing the eggs

Have the oven heating and the muffin cups greased before you whisk the filling. Egg mixture can cling to pan corners, so pay attention to the sides as well as the base. Follow the care instructions for your pan or liners. A silicone mold and a metal tin can behave differently; neither eliminates the need to check that the centers are cooked safely.

Cut vegetables small and manage moisture

Finely chopped spinach and small pepper pieces distribute more evenly among six cups than large strips. Wet cooked vegetables can release liquid and make the cups less pleasant. Drain them well and allow hot additions to cool appropriately before mixing. Do not pack the muffin cups with vegetables and then assume the eggs will fill every space; stir the mixture before dividing so the portions are more consistent.

Use temperature as the doneness check

The time range helps you plan, but oven behavior, pan material, and cup size all affect cooking. Check the centers with a suitable thermometer rather than relying on browned edges. A deeply browned top can coexist with a center that needs more time. Let the muffins rest briefly, then loosen the edges gently so they come out more cleanly.

Plan breakfast portions before freezing

Freeze cooled portions individually or separate them so you can take only what you need. Label the date and contents. Thaw in the refrigerator when appropriate and reheat cooked leftovers thoroughly. Pair the muffins with bread, fruit, or another side according to appetite. Keep a few breakfasts varied by rotating the side rather than preparing a completely different egg mixture every morning.

Frequently asked questions

Can I double the recipe?

Yes, using enough cups and checking each batch for doneness. Avoid overfilling cups; extra mixture should go into another prepared cup rather than being forced into the same tin.

Why do the muffins sink?

Some settling after baking is normal for this style of egg cup. Excess vegetable moisture or undercooking can worsen the texture. Check the centers and drain wet additions.

Can I leave out feta?

You can omit it or choose a suitable alternative, but flavor and saltiness change. If avoiding milk, check the milk ingredient as well as the cheese.
