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
- 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.
- In a large bowl, whisk the eggs, milk, salt, and pepper until well combined and slightly frothy.
- Stir in the cheese, ham, bell pepper, and onion until evenly distributed.
- Pour the egg mixture into the prepared muffin cups, filling each about 3/4 full. Use a ladle or measuring cup for even distribution.
- 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.
- 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.
- 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.
