A cozy, hearty frittata made in a cast iron skillet with eggs, roasted veggies, cheese, and optional meat, perfect for a quick and satisfying brunch.

Ingredients

Scale
  • 8 large eggs (room temperature for best fluffiness)
  • ½ cup whole milk or half-and-half
  • 1 cup sharp cheddar, shredded
  • 1 cup mixed bell peppers and zucchini, chopped (fresh or leftover roasted veggies)
  • ½ medium yellow onion, finely diced
  • 2 cloves garlic, minced
  • ½ cup cooked bacon or sausage, crumbled (optional)
  • 2 tbsp chopped fresh parsley or chives
  • Salt and pepper to taste
  • 1 tbsp olive oil or butter for sautéing

Instructions

  1. Preheat your oven to 375°F (190°C).
  2. Heat 1 tbsp olive oil or butter in a 10-12 inch cast iron skillet over medium heat. Add diced onion and cook for 3-4 minutes until translucent and fragrant.
  3. Add minced garlic and sauté for 30 seconds to 1 minute.
  4. Stir in chopped bell peppers, zucchini, and crumbled bacon or sausage if using. Cook for 3-5 minutes until warmed through and slightly caramelized. Season with salt and pepper.
  5. In a large mixing bowl, whisk 8 large eggs with ½ cup whole milk or half-and-half until fully combined and slightly frothy. Add salt and pepper to taste.
  6. Stir shredded cheddar and chopped fresh herbs into the egg mixture, reserving a small handful of cheese for topping.
  7. Spread the sautéed veggies and meat evenly in the skillet, then pour the egg mixture over them. Gently stir to distribute evenly.
  8. Cook undisturbed over medium heat for 3-4 minutes until edges start to set but center is still loose.
  9. Sprinkle the reserved shredded cheddar on top.
  10. Transfer the skillet to the preheated oven and bake for 12-15 minutes until the frittata is puffed and set in the center (a knife inserted should come out clean).
  11. Remove from oven and let rest for 5 minutes before slicing and serving.

Notes

Use room temperature eggs for fluffier texture. Do not overfill skillet to ensure even cooking. Let frittata rest after baking for cleaner slices. Watch closely near end of baking to avoid overcooking. For dairy-free, substitute milk with almond or oat milk and cheese with plant-based alternatives.
