What Ingredients You Will Need

This loaded cast iron frittata calls for straightforward, wholesome ingredients that come together easily to pack big flavor and texture. Most are pantry or fridge staples, making it perfect for those last-minute brunch plans.

• Eggs: 8 large eggs (room temperature for best fluffiness)
• Milk or Cream: ½ cup whole milk or half-and-half (adds richness)
• Cheese: 1 cup sharp cheddar, shredded (I recommend Cabot for great melt and flavor)
• Roasted Vegetables: 1 cup mixed bell peppers and zucchini, chopped (use fresh or leftover roasted veggies)
• Onion: ½ medium yellow onion, finely diced (for sweetness and depth)
• Garlic: 2 cloves, minced (fresh garlic always wins here)
• Cooked Bacon or Sausage: ½ cup, crumbled (optional but adds hearty smoky notes)
• Fresh Herbs: 2 tbsp chopped parsley or chives (brightens the dish)
• Salt & Pepper: To taste
• Olive Oil or Butter: 1 tbsp for sautéing

If you want to switch things up, almond milk or oat milk works fine for a dairy-free alternative, and swapping cheddar for feta or mozzarella gives a different but equally tasty twist. The key is to use firm, fresh veggies so they hold their texture instead of becoming mushy inside the frittata.

Equipment Needed

• Cast Iron Skillet: About 10-12 inches in diameter. This is crucial for even cooking and that signature crispy edge.
• Mixing Bowl: To whisk your eggs and milk together.
• Whisk or Fork: For beating the eggs until fluffy.
• Spatula: A silicone or wooden spatula to gently fold in ingredients.
• Oven Mitts: Cast iron gets seriously hot, so mitts are a must for handling the skillet safely.

If you don’t have a cast iron skillet, a heavy oven-safe nonstick skillet works, but you won’t get quite the same texture. I’ve tried both, and honestly, the cast iron version has a rustic charm and flavor that’s hard to beat. Keeping your skillet well-seasoned also helps prevent sticking and makes cleanup easier. For budget-friendly options, Lodge offers reliable cast iron skillets that last forever.

Preparation Method

1. Preheat your oven: Set it to 375°F (190°C). This ensures the frittata cooks evenly through the top and edges.
2. Sauté the aromatics and veggies: Heat 1 tbsp olive oil or butter in your cast iron skillet over medium heat. Add diced onion and cook for 3-4 minutes, until translucent and fragrant. Toss in garlic and sauté for an additional 30 seconds to 1 minute.
3. Add roasted veggies and meat: Stir in chopped bell peppers, zucchini, and crumbled bacon or sausage if using. Cook for 3-5 minutes until everything is warmed through and slightly caramelized. Season with a pinch of salt and pepper.
4. Whisk eggs and milk: In a large bowl, beat 8 large eggs with ½ cup whole milk or cream until fully combined and slightly frothy. Add a pinch of salt and pepper to taste.
5. Combine cheese and herbs: Stir in shredded cheddar and chopped fresh herbs into your egg mixture, reserving a small handful of cheese for topping.
6. Pour egg mixture over veggies: Spread the sautéed ingredients evenly in the skillet, then pour the egg mixture on top. Gently stir to distribute everything evenly.
7. Cook on stovetop briefly: Let it cook undisturbed over medium heat for about 3-4 minutes until the edges start to set but the center is still loose.
8. Top with reserved cheese: Sprinkle the remaining shredded cheddar on top for a bubbly, golden crust.
9. Bake in the oven: Transfer the skillet to your preheated oven. Bake for 12-15 minutes or until the frittata is puffed and firmly set in the center (a knife inserted should come out clean).
10. Rest and serve: Remove from the oven and let it cool for 5 minutes before slicing. This resting time helps the layers settle and makes for cleaner cuts.

Keep an eye on the frittata near the end of baking to avoid overcooking, which can make it rubbery. If the edges brown too fast, tent loosely with foil. The smell of caramelized onions and melted cheese will be your best guide that it’s ready!

Cooking Tips & Techniques

One thing I learned early on is that room temperature eggs make a noticeable difference in fluffiness. Cold eggs straight from the fridge can slow down cooking and cause uneven texture. Also, don’t rush the sautéing step—getting a little color and caramelization on those veggies adds depth you won’t get by just tossing everything raw into the skillet.

Another trick is not to overfill your skillet. If you pack it too full, the frittata won’t cook evenly. Aim for ingredients that sit comfortably below the rim. And remember to let it rest after baking; I know it’s tempting to dig in immediately, but that pause really helps.

When mixing the eggs and milk, whisk until you see a slight foam on top—that means you’re incorporating air, which gives a lighter texture. I’ve made this recipe with both half-and-half and milk, and while cream makes it richer, milk keeps it lighter but still creamy.

Finally, if your oven tends to run hot, check the frittata a few minutes before the suggested time. It can turn from perfect to overdone surprisingly fast, especially in cast iron.

Variations & Adaptations

• Vegetarian version: Skip the meat and add extra hearty veggies like mushrooms, spinach, or tomatoes. A sprinkle of feta adds a tangy punch.
• Low-carb adaptation: Substitute milk with unsweetened almond milk and load up on green veggies like kale and broccoli to keep it keto-friendly.
• Spicy twist: Add diced jalapeños or a pinch of cayenne pepper to the egg mixture for a subtle kick.

For a dairy-free option, try coconut milk in place of cream and use a plant-based cheese substitute. I once swapped cheddar for smoked gouda, which gave the frittata a lovely smoky undertone that my brunch guests couldn’t stop talking about. You can also experiment with different herbs—thyme and rosemary work beautifully, especially in fall or winter versions.

Serving & Storage Suggestions

This frittata is best served warm, straight from the skillet, but it also tastes great at room temperature. I like to cut it into wedges and garnish with extra fresh herbs or a dollop of sour cream for a little tang. It pairs wonderfully with a simple green salad or crusty bread to round out the meal.

If you have leftovers, store them covered in the refrigerator for up to 3 days. To reheat, pop a slice in the microwave for about 60 seconds or warm it gently in a nonstick pan to bring back some crispiness. You can also freeze individual slices wrapped tightly in plastic wrap and foil for up to a month—just thaw overnight in the fridge before reheating.

Flavors deepen the next day, making it an even better option for make-ahead brunches or quick lunches. Honestly, this frittata gets better with time, so don’t hesitate to plan ahead.
