A delightful and easy-to-make frittata featuring the classic combination of tomato and basil, perfect for a healthy and satisfying meal.
Preheat your oven to 375°F (190°C).
Ensure the oven is fully preheated for even cooking.
Heat the olive oil in an oven-safe skillet over medium heat.
Use a skillet with a non-stick surface for easy cleanup.
Sauté the chopped onion until it becomes translucent.
Stir occasionally to prevent the onion from burning.
Add the sliced tomatoes to the skillet and cook for 2 minutes.
Use ripe tomatoes for the best flavor.
In a mixing bowl, whisk together the eggs, milk, salt, and pepper.
Whisk thoroughly to ensure a fluffy texture.
Pour the egg mixture over the vegetables in the skillet.
Distribute the vegetables evenly for consistent flavor.
Sprinkle the cheese and basil over the top.
Use freshly grated cheese for better melting.
Transfer the skillet to the oven and bake for 15-20 minutes, or until the frittata is set and golden.
Check the center with a toothpick to ensure it's fully cooked.
Remove from the oven, let cool slightly, and serve warm.
Garnish with extra basil leaves for presentation.
