Welcome to your new favorite brunch star: a Parmesan Herb Frittata that is delightfully fluffy, packed with savory cheeses, and brightened by fresh herbs. This simple yet elegant dish is perfect for any meal, from a quick weekday breakfast to a leisurely weekend brunch with friends. Serve it alongside a crisp green salad, a generous portion of roasted potatoes, or your favorite breakfast sides for a truly satisfying experience.

Imagine this: a golden slice of frittata, its edges lightly caramelized, a forkful of crispy seasoned potatoes, and a refreshing bite of salad. Could there be a more perfect brunch meal? I truly don’t think so. Frittatas are a culinary marvel – effortlessly elegant, incredibly versatile, and surprisingly simple to prepare, making them a fantastic choice for both novice and experienced cooks alike.
One of the many reasons I adore frittatas is their inherent flexibility. They offer a blank canvas for a myriad of flavors, allowing you to experiment with various cheeses, add your preferred meats, or incorporate an abundance of seasonal vegetables. Think of a frittata as a versatile, crustless quiche or a quick, wholesome breakfast casserole. The best part? Most frittata recipes, including this one, typically begin on the stovetop to build a flavor base, then transition seamlessly into the oven to bake to fluffy perfection. For this reason, I highly recommend using a cast iron skillet, as it performs beautifully in both environments, significantly cutting down on that post-meal dirty dish pile – a win-win in my book!
While my blog features several delicious frittata creations, this particular Parmesan Herb Frittata recipe holds a special place in my heart. It’s a testament to how much flavor can be achieved with minimal effort. The robust saltiness of the Parmesan cheese truly shines through, complementing the creamy eggs and fragrant herbs. The result is nothing short of heavenly – a dish that tastes complex and gourmet, but is a breeze to whip up.

Key Ingredients for Your Fluffy Frittata
This recipe calls for a straightforward list of ingredients, most of which you likely already have in your pantry or refrigerator. The full detailed list and instructions are provided in the recipe card below, but here’s a glimpse of what you’ll need to create this delightful dish:
- **Olive or Avocado Oil:** For sautéing and adding a rich base.
- **Onion & Minced Garlic:** The aromatic foundation for incredible flavor.
- **Jarred Roasted Red Peppers:** Adds a subtle sweetness and vibrant color.
- **Fresh Eggs:** The core of our frittata, providing that light, fluffy texture.
- **Milk of Choice:** Any milk works, adding to the frittata’s creamy consistency.
- **Shredded Mozzarella & Grated Parmesan:** A dynamic duo for cheesy goodness and savory depth.
- **Fresh Parsley:** For a burst of fresh, herbaceous flavor.
- **Essential Seasonings:** A blend of salt, pepper, dried oregano, dried basil, cayenne pepper, and ground mustard to elevate the taste.
Simple Steps to Frittata Perfection
Creating this frittata is a simple process, beginning with building a flavorful base. First, you’ll sauté the diced onion in your trusty cast iron skillet over medium-high heat until it begins to soften and become translucent. Towards the end of the onion’s cooking time, add the minced garlic and continue to sauté for about one minute, or until the garlic is fragrant and lightly golden. Be careful not to burn the garlic, as it can turn bitter.
While your aromatics are cooking, in a separate bowl, whisk together the eggs, milk, and all the specified seasonings until thoroughly combined and slightly frothy. This ensures an even distribution of flavor and a lighter texture.
Once the onion and garlic are tender and golden, turn off the heat. Spread them evenly across the bottom of the skillet. Next, dice the jarred roasted red peppers and scatter them over the onion and garlic mixture. Then, layer the shredded mozzarella cheese, grated Parmesan cheese, and finally, sprinkle the chopped fresh parsley generously over the top. Gently pour your whisked egg mixture over all the ingredients in the skillet, ensuring everything is submerged.
Now, it’s time for the oven! Transfer the skillet to a preheated oven and bake until the center is just set and the frittata is puffed and golden brown. The frittata might bubble quite a bit in the oven, but don’t worry – it will settle beautifully as it rests. Allow it to rest for a few minutes after removing it from the oven before slicing and serving. This resting period helps the frittata firm up and makes for cleaner slices.

Choosing the Right Cast Iron Skillet for Frittatas
Cast iron skillets are available in various sizes, but the 10-inch and 12-inch versions are the most common. For frittata recipes, I consistently find that a 10-inch cast iron skillet yields the best results. While my 12-inch skillet is fantastic for larger tasks like frying bacon for a crowd, it can cause your frittata to spread too thinly, leading to a less substantial and potentially overcooked outcome. Sticking with a 10-inch skillet ensures a perfectly thick, fluffy frittata with a delightful rise.
Essential Cast Iron Skillet Care Tips
A well-maintained cast iron skillet boasts a naturally nonstick surface. If yours has been seasoned correctly and cared for, you should have no issues with food sticking. However, if your cast iron skillet hasn’t been regularly seasoned or feels a bit rough, a quick preventative step can save you trouble. Before adding any ingredients for this frittata, wipe the inside of your skillet with a very thin layer of olive oil. This extra bit of oil creates a barrier, helping to ensure your frittata slides out easily.
After each use, and after cleaning (ideally with hot water and a stiff brush, avoiding harsh soaps), it’s crucial to re-season your skillet. Wipe a very thin layer of olive oil over the entire inside surface – just enough to give it a glossy sheen without any pooling. Excess oil will become sticky over time. Proper care will not only prevent sticking but also build up that coveted nonstick seasoning, making you fall in love with your cast iron skillet all over again!
Can I Use a Pie Plate or Other Baking Dish?
The primary advantage of using a cast iron skillet for this frittata recipe is its dual functionality: it can go from stovetop to oven without skipping a beat, which means fewer dishes to wash! However, if you don’t own a cast iron skillet or prefer to use another type of bakeware, you absolutely can. A 9 or 10-inch pie plate or a 10×10-inch baking dish makes an excellent substitute. I do not recommend using a baking dish larger than 10×10 inches, as the egg mixture will spread too thin, resulting in a very flat and likely overcooked frittata.
Since most pie plates and standard baking dishes are not stovetop-safe, you’ll need to modify the initial steps slightly. Simply sauté the onion and garlic in a separate stovetop-safe pan first. Once cooked, transfer the aromatic mixture to your chosen baking dish, then proceed with layering the cheeses, peppers, and herbs, and finally pouring in the egg mixture before baking.

Make-Ahead Frittata: Can You Prep This in Advance?
Yes, absolutely! Frittatas are fantastic for meal prep. You can prepare the frittata entirely the night before, following all the steps up to the point of baking. Cover the skillet or baking dish tightly with a lid or aluminum foil and refrigerate it overnight. The next morning, simply remove the lid or foil and bake it according to the recipe instructions. This makes for a super convenient and delicious breakfast or brunch with minimal morning effort.
Freezing Your Parmesan Herb Frittata
Frittatas freeze exceptionally well, making them an ideal candidate for batch cooking and future meals. While some people are particular about the texture of reheated eggs, I personally find that the texture of a frittata remains excellent whether it’s fresh or reheated after freezing. If you choose to freeze this frittata, allow it to cool completely after baking. Once cooled, slice it into individual portions and store them in an airtight container or a freezer-safe bag. When you’re ready to enjoy a slice, simply thaw it (either overnight in the refrigerator or quickly in the microwave) and then reheat it in the microwave or in a preheated oven at 350 degrees Fahrenheit (175 degrees Celsius) until warmed through. This is perfect for grab-and-go breakfasts!
Storing Leftover Frittata
Any leftover frittata can be stored in an airtight container in the refrigerator for up to 4 days. It makes a wonderful quick breakfast or light lunch throughout the week. You can enjoy it cold or gently reheat it in the microwave or oven.
Serving Suggestions for Your Frittata
This Parmesan Herb Frittata is incredibly versatile and pairs well with a variety of sides. For a classic breakfast or brunch, consider serving it with crispy bacon, a medley of roasted potatoes, or a fresh fruit salad. For a lighter meal, a simple green salad with a vinaigrette dressing is perfect. You could also serve it with toasted artisan bread, a dollop of sour cream or Greek yogurt, or even a side of sautéed greens. The possibilities are endless, making it easy to tailor this dish to any occasion or preference.

Ingredients
- 1 tbsp olive oil, extra virgin
- 1/2 medium white or yellow onion, diced
- 1 tbsp garlic, minced
- 8 eggs
- 1/2 cup milk of choice
- 3/4 tsp salt
- 1/2 tsp dried oregano
- 1/2 tsp dried basil
- 1/4 tsp cayenne pepper
- 1/4 tsp ground mustard
- 1/4 tsp black pepper
- 2 roasted red peppers, jarred
- 3/4 cup shredded mozzarella
- 3/4 cup grated parmesan
- 2 tbsp fresh parsley, chopped
Instructions
-
Preheat oven to 425 degrees Fahrenheit (220 degrees Celsius).
-
Add olive oil to a 10-inch cast iron skillet over medium-high heat. Once hot, add diced onion and sauté, stirring with a spatula, until it begins to soften, about 5-7 minutes. Then, add minced garlic to the skillet and sauté for about one minute until fragrant and lightly golden.
-
Meanwhile, in a medium bowl, whisk together the eggs, milk, salt, oregano, basil, cayenne pepper, ground mustard, and black pepper until well combined.
-
When the onion and garlic are finished cooking, turn off the stove. Spread the cooked onion and garlic evenly across the bottom of the skillet. Dice the jarred roasted red peppers and distribute them over the onion and garlic. Layer the shredded mozzarella cheese, then the grated Parmesan cheese, and finally, sprinkle the chopped fresh parsley on top. Pour the whisked egg mixture carefully over all the ingredients.
-
Transfer the skillet to the preheated oven and bake until the center of the frittata is just set and the edges are lightly golden, typically 16 to 20 minutes. The center should not be overly jiggly. Remove from the oven and let it rest for a few minutes before slicing and serving. The frittata may puff up significantly during baking but will settle down as it rests.
