Vegetable Egg Muffins

Vegetable Egg Muffins

These individual baked egg cups combine eggs, vegetables, and cheese in a portable breakfast. Briefly cooking watery vegetables first prevents soggy centers and helps the muffins release cleanly. They can be prepared ahead and reheated one serving at a time.

Equipment and timing

• Standard 12-cup nonstick muffin pan
• Medium skillet
• Mixing bowl and whisk
• Instant-read thermometer
• Thin silicone spatula

Yield: 12 egg muffins, 6 servings
Preparation: 15 minutes
Cooking: 22 to 27 minutes total
Oven: 350°F/175°C

Ingredients

• 1 teaspoon olive oil
• 1/2 cup finely diced red bell pepper
• 1/2 cup finely chopped mushrooms
• 2 cups baby spinach, chopped
• 10 large eggs
• 1/4 cup milk
• 1/2 teaspoon fine salt
• 1/4 teaspoon black pepper
• 1/2 teaspoon garlic powder
• 1/2 cup shredded cheddar cheese
• 2 tablespoons sliced scallions
• Nonstick cooking spray

Method

1. Heat the oven to 350°F/175°C and coat every muffin cup generously with nonstick spray, including the top surface.
2. Heat olive oil in a skillet over medium heat. Cook bell pepper and mushrooms for 4 to 5 minutes, until their moisture has evaporated. Add spinach and stir just until wilted. Cool for several minutes.
3. Whisk eggs, milk, salt, pepper, and garlic powder until the whites and yolks are fully blended. Stir in the vegetable mixture, cheese, and scallions.
4. Divide evenly among the 12 cups, filling each about three-quarters full. Stir the bowl between pours so the vegetables stay evenly distributed.
5. Bake 18 to 22 minutes, until the centers are set and register at least 160°F/71°C. Rest in the pan for 5 minutes, loosen the edges with a thin silicone spatula, and transfer to a rack.

Texture cues and troubleshooting

Egg muffins puff in the oven and settle as they cool; that is normal. A wet or rubbery center can result from uncooked vegetables, excess milk, or overbaking. Remove visible liquid from cooked vegetables before adding them. Begin checking early and rely on both a set center and temperature rather than deep browning.

Silicone liners release easily, but paper liners often stick to eggs. A well-greased nonstick metal pan gives browned edges. Letting the cups rest briefly helps them firm, but leaving them in the pan too long traps steam and dampens the bottoms.

Substitutions and storage

Use cooked broccoli, zucchini, or asparagus in place of the listed vegetables, keeping the total quantity similar and draining moisture. Feta, Swiss, or Monterey Jack can replace cheddar. Cooked diced ham may be added, but raw meat must be cooked safely before entering the egg mixture.

Refrigerate within 2 hours in a covered container and use within 4 days. Reheat until steaming hot, about 20 to 30 seconds per muffin in a microwave, checking between intervals. Freeze cooled muffins for up to 2 months and thaw overnight in the refrigerator before reheating.
