These Baked Egg Breakfast Cups are a tasty way to kickstart your day! They are packed with eggs and your favorite veggies or meats, baked to perfection in a muffin tin.
Perfect for busy mornings, you can make a batch ahead of time and grab one on your way out. I love to add cheese on top—it makes them even yummier! 🧀😋
Key Ingredients & Substitutions
Eggs: Eggs are the star of this dish. Large eggs provide the best structure and flavor. If you’re vegan or looking to lower cholesterol, consider using egg substitutes like silken tofu or a flaxseed mixture (1 tablespoon ground flaxseed with 2.5 tablespoons water).
Bell Pepper: Red bell pepper adds sweetness and color. You can swap it for green bell pepper if you prefer a stronger taste, or even zucchini or mushrooms for a different flair!
Onion: Red onion is milder and adds flavor. If you want a sweeter option, use yellow onions. You can also skip onions altogether if you’re not a fan!
Leafy Greens: Spinach adds nice nutrition. You can substitute kale or Swiss chard, or omit greens if you’re not into them, but they’re packed with benefits!
Cheese: I love using sharp cheddar, but feel free to experiment! Mozzarella, feta, or a dairy-free cheese are all solid substitutes.
How to Prevent Sticking to the Muffin Tin?
Nobody likes it when breakfast cups stick! Here’s how to ensure they slide out easily:
- Spray the muffin tin generously with non-stick cooking spray or brush it with olive oil. Don’t skip this step!
- Let the egg cups cool for a few minutes after baking. They will firm up slightly as they cool.
- Run a plastic or silicone spatula around the edges. This will help loosen them without damaging the tin.
Using these tips, you’re sure to have perfectly cooked cups that pop right out!

How Much Time Will You Need?
This delicious recipe will take about 10 minutes of prep time and 15-20 minutes of baking time, so you can have these tasty breakfast cups ready to enjoy in about 30 minutes!
Step-by-Step Instructions:
1. Preheat the Oven and Prepare Your Muffin Tin:
Start by preheating your oven to 375°F (190°C). While it’s warming, lightly grease a 6-cup muffin tin with non-stick cooking spray or a little olive oil to ensure your breakfast cups don’t stick.
2. Beat the Eggs:
In a medium bowl, crack open 4 of the eggs. Add a pinch of salt and pepper. Beat them together until they are just blended and a pretty yellow color.
3. Add the Veggies:
Next, take your diced red bell pepper, red onion, chopped spinach or kale, and parsley. Evenly divide them among the 6 muffin cups. This will give your breakfast cups a colorful and nutritious base.
4. Pour in the Egg Mixture:
Now, pour the beaten eggs over the veggie mix in each muffin cup. Fill each one about 2/3 full, leaving a little room for the egg to rise as it bakes.
5. Add an Egg on Top:
For a delicious finish, crack an egg on top of each filled muffin cup. Try to keep the yolk intact for that lovely look when you serve them!
6. Sprinkle the Cheese:
Finally, sprinkle your choice of shredded cheese over each muffin cup. This will melt beautifully and add extra flavor!
7. Bake to Perfection:
Place the muffin tin in your preheated oven and bake for 15-20 minutes. Keep an eye on them until the egg whites are set and the edges are golden brown. You want them fully cooked but still soft on the inside.
8. Cool and Remove:
Once they’re done, take the muffin tin out of the oven and let them cool for a few minutes. Then, gently run a knife around the edges to help ease the egg cups out.
9. Serve and Enjoy:
Serve your warm Baked Egg Breakfast Cups right away. You can season them with extra salt and pepper, if you like, and sprinkle some more parsley on top for a bit of color!
Enjoy your hearty, nutritious Baked Egg Breakfast Cups—perfect for busy mornings or a cozy breakfast at home!
Can I Use Egg Whites Only in This Recipe?
Absolutely! You can substitute the whole eggs with egg whites for a lighter version. Just use about 1/4 cup of egg whites per egg, so you’ll need 1.5 cups total for this recipe.
How Do I Store Leftover Baked Egg Breakfast Cups?
Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, simply warm them in the microwave for 30-45 seconds or until heated through.
Can I Customize the Fillings?
Definitely! Feel free to mix and match your favorite vegetables, such as zucchini, mushrooms, or even cooked bacon or sausage for added flavor. Just be sure to keep the total volume around 1.5 cups.
Can I Freeze These Breakfast Cups?
Yes! Baked Egg Breakfast Cups freeze well. Allow them to cool completely, then wrap each cup individually in plastic wrap and place them in a freezer-safe bag. They will keep for about 2 months. To reheat, thaw in the fridge overnight and warm in the oven or microwave.
