Omelet Cups Recipe for Easy Meal Prep

Omelet cups are a portable, protein-packed breakfast made by baking a whisked egg mixture with your favorite fillings in a muffin tin. They are perfect for busy mornings, meal prep, or a quick brunch, and they are endlessly customizable. This recipe delivers fluffy, flavorful cups that hold together well and are easy to grab on the go.

Ingredients

  • 8 large eggs
  • 1/4 cup (60 ml) milk (any kind, or water)
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/2 cup (50 g) shredded cheddar cheese
  • 1/2 cup (75 g) diced cooked ham or crumbled cooked sausage
  • 1/4 cup (40 g) diced bell pepper
  • 2 tablespoons (20 g) diced onion
  • 1 tablespoon (15 ml) olive oil or butter, for greasing the muffin tin

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 12-cup muffin tin with olive oil or butter, or line with silicone muffin cups.
  2. In a large bowl, whisk the eggs, milk, salt, and pepper until well combined and slightly frothy.
  3. Stir in the cheese, ham, bell pepper, and onion until evenly distributed.
  4. Pour the egg mixture into the prepared muffin cups, filling each about 3/4 full. Use a ladle or measuring cup for even distribution.
  5. Bake for 18–20 minutes, until the eggs are set and the tops are lightly golden. The internal temperature of the egg cups should reach 160°F (71°C) as the safe minimum for egg dishes, per USDA FSIS guidelines. Check with a food thermometer inserted into the center of a cup.
  6. Remove from the oven and let cool in the pan for 5 minutes. Run a knife around the edges to loosen, then gently lift out with a fork or spatula.
  7. Serve warm, or let cool completely and store for later.

Tips

  • Don’t overfill: Fill cups only 3/4 full; eggs puff up as they bake and will overflow if too full.
  • Customize your add-ins: Use any combination of cooked vegetables, meats, or cheeses. Avoid raw watery veggies like tomatoes or zucchini unless you sauté them first to remove excess moisture.
  • Use silicone liners: They make removal effortless and cleanup a breeze. If using metal, grease generously.
  • Make them dairy-free: Swap milk for water or unsweetened plant milk, and omit cheese or use dairy-free shreds.

Serving Suggestions

Serve omelet cups with a side of fresh fruit, toast, or a simple green salad for a complete meal. They also pair well with roasted potatoes or a dollop of salsa or hot sauce for extra flavor. For brunch, arrange them on a platter with yogurt parfaits and coffee.

Variations

  • Vegetarian: Omit meat and add sautéed mushrooms, spinach, or zucchini.
  • Southwest: Add black beans, corn, and a pinch of cumin; top with salsa and avocado.
  • Mediterranean: Use feta, sun-dried tomatoes, and olives; add a sprinkle of oregano.
  • Bacon and chive: Use cooked bacon bits and fresh chives instead of ham and onion.

Storage and Reheating

Store cooked omelet cups in an airtight container in the refrigerator for up to 4 days. To freeze, place them in a single layer on a baking sheet, freeze until solid, then transfer to a freezer bag for up to 3 months. Reheat refrigerated cups in the microwave for 30–60 seconds, or in a 350°F (175°C) oven for 5–10 minutes. Frozen cups can be reheated directly in the microwave for 1–2 minutes, or thaw overnight in the fridge.

Frequently Asked Questions

Can I make omelet cups ahead of time? Yes, they are ideal for meal prep. Bake them, cool completely, and store in the fridge for up to 4 days. Reheat as needed.

Why are my omelet cups sticking to the pan? This usually happens if the pan isn’t greased well enough. Use a generous amount of butter or oil, or use silicone liners. Let them cool for a few minutes before removing—they release more easily when slightly cooled.

Can I use egg whites only? Absolutely. Use 8 egg whites (about 1 cup / 240 ml) instead of whole eggs. The texture will be slightly less rich, but they will still be delicious. Add a little extra cheese or veggies for flavor.

How do I know when they are done? The centers should be set and not jiggle. A food thermometer should read 160°F (71°C). If they start to brown too much on top, cover with foil for the last few minutes.

Can I make them without a muffin tin? Yes, you can use ramekins or a small baking dish. Adjust baking time accordingly—ramekins may need a few extra minutes, and a dish will need about 25–30 minutes.

What can I substitute for milk? Water, cream, or unsweetened plant milk all work. Milk adds a bit of creaminess, but water keeps them lighter. Use the same amount.
