Zucchini, Red Pepper & Cherry Tomato Baked Egg Cups
Tender individual baked egg cups studded with finely diced zucchini, sweet red bell pepper, and halved cherry tomatoes, brightened with sliced scallions and a hint of dried oregano and baked until just set.
Why You'll Love This Recipe
These are portable, hand-held egg cups built for a busy morning, made almost entirely from summer vegetables and eggs. They suit anyone who wants a warm, savory start to the day without a stack of dishes or a long stovetop watch, and they are just as welcome as a light lunch or a protein-rich snack. Because each cup bakes in its own well, everyone gets an even share of vegetables and a neat, self-contained portion.
Dice the zucchini fine, and divide the vegetables before the eggs go in. Zucchini holds a lot of water, so cutting it small lets it cook through and shed moisture into the small space rather than leaving a raw, wet bite. Whisking the eggs until frothy beats in a little air, which gives the cups their gentle puff, and pouring the eggs only until they just cover the vegetables keeps each cup from overflowing as it rises. The short rest after baking lets the set eggs firm up so they lift out in one piece.
The eggs carry the protein and the vegetables carry the sweetness and the color. Red bell pepper and cherry tomatoes turn jammy and sweet in the heat, scallions add a mild savory note, and dried oregano ties it together with a warm, herbal edge. The result is filling without being heavy, with real texture from the vegetables and enough protein to carry you to your next meal.
Ingredients
- 6 large eggs
- 1 cup zucchini, finely diced
- 1/2 cup red bell pepper, diced
- 1/2 cup cherry tomatoes, halved
- 2 scallions, thinly sliced
- 1 tsp dried oregano
- 1 tbsp avocado oil
- 1/2 tsp salt
Instructions
- Preheat and oil the tin: Preheat the oven to 350°F (175°C). Brush the inside of each cup of a muffin tin with the avocado oil, coating the bottom and sides well so the baked eggs release cleanly.
- Prep the vegetables: Finely dice the zucchini into small pieces so it softens fully in the baking time. Dice the red bell pepper. Halve the cherry tomatoes. Trim and thinly slice the scallions, using both the white and green parts.
- Fill the cups with vegetables: Divide the diced zucchini, red bell pepper, halved cherry tomatoes, and sliced scallions evenly among the cups, filling each a little over halfway with vegetables.
- Season and whisk the eggs: Crack the eggs into a bowl or large measuring cup, add the dried oregano and salt, and whisk vigorously until the yolks and whites are fully blended and the mixture looks slightly frothy on top.
- Pour the eggs over the vegetables: Pour the whisked eggs into each cup until they just cover the vegetables, leaving a little room at the top since the eggs puff as they bake.
- Bake until set: Bake for 18 to 20 minutes, until the eggs are puffed and the centers no longer jiggle when you gently nudge the tin. Let the cups rest in the tin for 5 minutes, then run a thin knife or small spatula around each one and lift them out.
Variations
- Add a savory meat: Fold cooked, crumbled breakfast sausage or diced ham into the vegetables before pouring in the eggs for a heartier, more filling cup. This adds meat.
- Smoky and warm: Whisk a pinch of smoked paprika and a little black pepper into the eggs along with the oregano for a deeper, gently smoky flavor without changing the makeup of the dish.
- More greens: Add a handful of finely chopped spinach or baby kale to the vegetable mix; it wilts down as it bakes and adds color and an earthy note.
- Fresh herb finish: Swap the dried oregano for chopped fresh basil or dill, stirring it into the eggs just before pouring for a brighter, garden-fresh taste.
- A little heat: Sprinkle red pepper flakes or a small amount of finely diced fresh chile over the vegetables before adding the eggs for a warming kick that plays well with the sweet tomatoes.
Storage & Leftovers
Keep the cooled egg cups in an airtight container in the refrigerator for up to four days. Let them cool completely before sealing so condensation does not collect and make them soggy.
To reheat, warm a cup or two in the microwave in short bursts of about 20 to 30 seconds until just heated through; longer bursts overcook the eggs and turn them rubbery. For a fresher texture, reheat them in a 300°F (150°C) oven for a few minutes instead.
For a make-ahead breakfast, bake a full batch at the start of the week and refrigerate them. You can also dice the vegetables a day ahead and store them in a covered container so all that is left in the morning is whisking the eggs and filling the tin.
Notes & Tips
- Blot the zucchini: Zucchini is watery, so after dicing it, press it between paper towels or a clean kitchen towel to squeeze out some moisture. Drier zucchini keeps the finished cups from turning weepy.
- Grease generously: Eggs stick, so do not skimp when brushing the cups with avocado oil, and be sure to coat the sides all the way up. If your tin tends to grab, silicone liners or a well-oiled silicone tin make release effortless.
- Do not overfill: Stop pouring the eggs once they just cover the vegetables. The whisked eggs puff as they bake, and cups filled to the brim will spill over the edges and stick the tops together.
- Check doneness by the center: The edges set before the middle. Give the tin a gentle nudge, and if the center of each cup still jiggles like liquid, give it another minute or two; you want it puffed and just firm, not sloshing.
- Choose ripe tomatoes: Sweet, ripe cherry tomatoes make a real difference here since they concentrate and turn jammy in the oven. Halve them rather than leaving them whole so they release moisture as they bake instead of bursting.
- Serve them warm or cold: These are good straight from the oven, but they also hold up well eaten cold from the fridge, which makes them handy to pack for a portable breakfast or a light snack later in the day.
Nutrition & Mindful Eating
- Eggs and vegetables in the same cup is the whole trick. The eggs set into a tender custard, the zucchini and pepper keep them from turning dense, and the cherry tomatoes burst as they bake and season everything around them.
- Eggs are what hold these together and what makes them worth eating at seven in the morning, carrying a complete protein and the choline in the yolks that the body uses for brain and cell health.
- Red bell pepper turns sweeter and softer in the oven than it is raw, and it stays brightly colored all the way through the bake, bringing along the vitamin C it is unusually rich in.
- Zucchini gives up its water as it bakes, which is what keeps the cups tender, and it sits in the background as texture more than flavor while adding gentle fiber.
- Dried oregano, scallions and salt are the seasoning, and they matter more than they sound. The oregano goes herbal and slightly bitter against the sweet tomato, the scallion greens stay sharp, and the salt is what stops eggs from tasting flat.
- As you eat, wait for the moment a baked tomato gives way and floods the cup, and take these sitting down so breakfast is something you have rather than something you finish standing at the counter.
Frequently Asked Questions
Why did my egg cups come out watery on the bottom?
That is almost always from the zucchini, which releases a lot of water as it bakes. Dice it finely and blot it dry before it goes into the tin, and make sure you bake until the centers are fully set rather than still jiggling.
Can I use a different oil to grease the tin?
Yes. Any neutral, oven-stable oil works for coating the cups. Just coat the sides well so the eggs release cleanly, since that is the main job of the oil here.
How do I get them to release without breaking?
Two things: grease the cups generously, and let them rest in the tin for about five minutes after baking so they firm up. Then run a thin knife or small spatula around the edge of each cup before lifting it out.
Can I make these ahead for the week?
They are ideal for it. Bake a batch, cool them completely, and refrigerate in an airtight container for up to four days, then reheat a cup or two in short microwave bursts or briefly in a low oven when you want one.
