Description

Roast vegetable frittata turns leftover roasted vegetables into impressive breakfast, brunch, or dinner dish. Fluffy eggs and melted cheese combine with caramelized vegetables for versatile meal any time of day.


Ingredients

Scale
  • 3 cups roasted vegetables (any combination)
  • 8 large eggs
  • ¼ cup milk or cream
  • 1 cup shredded cheese (cheddar, mozzarella, or Gruyere)
  • 2 Tbsp olive oil or butter
  • ½ tsp salt
  • ¼ tsp black pepper
  • ¼ tsp garlic powder
  • Fresh herbs for garnish (basil, parsley, or chives)

Instructions

1. If roasting fresh vegetables, preheat oven to 425°F. Toss vegetables with olive oil, salt, and pepper. Roast 25-30 minutes until tender and caramelized. Let cool slightly.

2. Reduce oven temperature to 375°F for frittata cooking.

3. In large bowl, whisk together eggs, milk, salt, pepper, and garlic powder until well combined and slightly frothy. Stir in half the shredded cheese.

4. Heat oven-safe skillet over medium heat. Add olive oil or butter and swirl to coat bottom and sides of pan completely.

5. Add roasted vegetables to hot skillet, spreading them evenly across bottom. Let vegetables warm through for 2-3 minutes.

6. Pour egg mixture over vegetables, using spatula to distribute evenly. Sprinkle remaining cheese on top.

7. Cook on stovetop 3-5 minutes without stirring. Eggs will begin setting around edges while center remains slightly liquid.

8. Transfer skillet to preheated oven. Bake 15-20 minutes until eggs are completely set and top is lightly golden. Frittata should puff slightly and not jiggle when gently shaken.

Notes

Storage: Refrigerate up to 4 days. Tastes great cold or reheated in microwave.

Freezing: Wrap individual slices and freeze up to 3 months. Thaw overnight in refrigerator.

Vegetables: Use any combination – bell peppers, zucchini, onions, broccoli, Brussels sprouts, sweet potatoes, mushrooms, tomatoes, asparagus.

Pro Tips: Let vegetables cool slightly before adding to prevent scrambling eggs. Run spatula around edges before serving.

Ingredient Notes

Any roasted vegetables work beautifully. Use leftovers from previous meals or roast fresh vegetables specifically for frittata. Cut vegetables into bite-sized pieces for even distribution.

Whole milk creates creamier texture than skim milk. Heavy cream makes ultra-rich frittata perfect for special occasions. Non-dairy milk works for dairy-free version.

Shredded cheese melts evenly throughout frittata. Pre-shredded cheese saves time but freshly shredded cheese melts smoother and tastes better.

Tips & Variations

Add cooked bacon or sausage for meat lovers version. Crumble cooked meat over vegetables before adding eggs.

Make Mediterranean-style with roasted red peppers, olives, feta cheese, and fresh oregano. This combination creates bright flavor-packed frittata.

Common Mistakes

  • Using non-oven-safe skillet which limits cooking options
  • Overcooking eggs on stovetop before transferring to oven
  • Not preheating oven properly, leading to uneven cooking
  • Using too many vegetables which prevents eggs from setting properly
  • Slicing too soon before frittata has time to set
  • Cooking at too high temperature which makes eggs rubbery
