High-Protein Pepperoni Breakfast Cups

I discovered these breakfast cups by accident on a Tuesday morning when I was frantically searching for something I could grab before a long commute. My usual scrambled eggs felt boring, and toast wasn't cutting it anymore—I wanted real sustenance. That's when it hit me: what if I baked all those pizza flavors I loved into portable little cups? The first batch came out golden and warm, and suddenly breakfast felt less like a rushed obligation and more like something I actually wanted to eat.

I made these for my brother last summer when he was staying with me, trying to get back into shape before his wedding. He was skeptical about breakfast cups until he tried one straight from the fridge—still good, still satisfying. By day three, he was asking if he could take the remaining batch home. That's when I knew this recipe had real staying power.

Ingredients

• 6 large eggs: Use the freshest ones you can find; they whisk smoother and bind everything together without any rubbery texture creeping in.
• 1/2 cup plain Greek yogurt (unsweetened): This is your secret weapon for creaminess and extra protein—don't skip it or substitute it with regular yogurt, which changes the whole texture.
• 1/4 cup milk: Whole milk creates a silkier custard, but any milk works in a pinch.
• 1/4 tsp salt and 1/4 tsp black pepper: Season generously because the filling adds richness; you need enough seasoning to shine through.
• 1/2 tsp dried oregano and 1/2 tsp dried basil: These dried herbs are the backbone of that pizza flavor—don't reduce them or the whole thing tastes like plain eggs.
• 3/4 cup shredded mozzarella cheese: Low-moisture mozzarella works better than fresh mozzarella, which releases too much water and makes the cups watery.
• 1/2 cup mini pepperoni slices: Mini pepperoni stays distributed; regular pepperoni tends to sink or clump, so chop it if that's all you have.
• 1/4 cup finely diced red bell pepper: The brightness cuts through the richness and adds a subtle sweetness that balances the salt.
• 2 tbsp finely diced red onion: Dice small or it becomes too sharp; the goal is a whisper of onion flavor, not a bite.
• 2 tbsp grated Parmesan cheese: Adds a salty, umami punch that makes people ask what that incredible flavor is.
• 2 tbsp pizza sauce: Use a good one with actual herbs, not just tomato; this makes the difference between tasting like pizza and tasting like leftovers.

Instructions

Heat your oven and prep your vessel:

Preheat to 375°F and grease your muffin tin well or line it with silicone cups, which honestly makes removal so much easier and less anxiety-inducing. If you're using paper liners, they tend to stick to the edges, so skip them.

Whisk the egg base until it's completely smooth:

Combine eggs, Greek yogurt, milk, salt, pepper, oregano, and basil in a bowl and whisk for about a minute until there are no lumps of yogurt hiding in corners. This is the texture base for everything, so smooth matters.

Combine all your filling ingredients in a separate bowl:

Mix mozzarella, pepperoni, bell pepper, red onion, Parmesan, and pizza sauce together so every element is evenly distributed. This prevents you from ending up with one cup that's all cheese and another that's all pepperoni.

Layer filling into each muffin cup:

Divide the filling evenly among the six cups, pressing it down slightly so it doesn't float when you add the egg mixture. This step takes about two minutes and genuinely matters for even cooking.

Pour the egg mixture carefully over the filling:

Fill each cup about three-quarters full, then use a fork to gently stir the egg mixture into the filling so everything mingles together. You'll see the cheese and pepperoni start to rise through the custard, which is exactly what you want.

Bake until the centers are just set:

Slide into the oven for 18 to 20 minutes until the tops are lightly golden and the centers don't jiggle when you gently shake the tin. Overbaking makes them rubbery, so pull them out when they're just barely set.

Cool briefly before releasing:

Let them rest for five minutes in the tin—this helps them firm up slightly and makes removal infinitely easier. Run a thin knife around the edges if you didn't use silicone liners.

Pin It

My coworker Marcus brought up that he'd been eating the same boring protein bar every morning for three years. I sent him home with four of these cups, and something shifted for him—suddenly breakfast was the best part of his day, something he looked forward to instead of something to endure. That's the moment I realized this recipe was about more than macros and convenience.

Storage and Make-Ahead Magic

These keep beautifully in the refrigerator for up to four days, which means you can batch them on Sunday and genuinely forget about breakfast planning for the rest of the week. Reheat gently in the microwave for about 60 to 90 seconds, and they taste nearly as good as fresh-baked. I've also frozen them successfully for up to three months, though they take a couple of extra minutes to reheat from frozen.

Variations That Still Feel Like Pizza

The beauty of this recipe is how adaptable it is without losing that pizza essence. I've made vegetarian versions with sautéed mushrooms and spinach that are just as satisfying, swapped the mozzarella for sharp cheddar or provolone when I wanted a different flavor profile, and even added a pinch of red pepper flakes for heat. The structure is forgiving as long as you keep the egg-to-filling ratio roughly the same.

Why These Work When Nothing Else Does

High-protein breakfasts are supposed to be boring—grilled chicken and sad vegetables, protein shakes, egg white omelets—but these prove that satisfying nutrition doesn't have to taste like punishment. They're portable enough to eat at your desk, flavorful enough that you won't crave donuts two hours later, and simple enough that you can make them without thinking. They've become my answer to almost every breakfast question.

• Make them the night before if you're rushing: They reheat just as well the next morning and give you five extra minutes of sleep.
• Serve with extra pizza sauce on the side: A tiny dish of sauce transforms them from great to something people actually talk about.
• Double the batch because they disappear fast: You'll make twelve thinking you're set for a week, and they'll be gone by Wednesday.

These breakfast cups became the thing I make for people when they're starting a health kick or just exhausted with typical meal prep. There's something about biting into one and getting that burst of melted cheese, pepperoni, and herbs that makes healthy eating feel like a choice instead of a chore.

Recipe FAQs

→ Can I make these breakfast cups ahead of time?

Absolutely. These cups meal prep beautifully—store them in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave for 30-60 seconds until warmed through.

→ What can I substitute for the pepperoni?

For a vegetarian option, replace pepperoni with sautéed mushrooms, spinach, or sun-dried tomatoes. You could also use cooked bacon bits, diced ham, or crumbled sausage for different protein variations.

→ Can I freeze these breakfast cups?

Yes, freeze cooled cups in a single layer on a baking sheet, then transfer to a freezer bag for up to 2 months. Thaw overnight in the refrigerator and reheat in the microwave or oven at 350°F until hot.

→ Why use Greek yogurt in the egg mixture?

Greek yogurt adds extra protein while creating a lighter, fluffier texture. The tanginess also complements the savory pizza flavors. Unsweetened plain yogurt works perfectly without affecting the taste profile.

→ Can I double this recipe?

Certainly. Simply use a standard 12-cup muffin tin and double all ingredients. The baking time remains the same—18-20 minutes until centers are set. You may need to rotate the pan halfway through for even cooking.

→ What's the best way to remove the cups from the tin?

Let them cool for 5 minutes before removing—this helps them set and release easily. Run a thin knife around the edges if needed, then gently lift using a spoon or fork. Silicone liners make removal even simpler.
