Step-by-Step Instructions

Preheat the Oven

Start by preheating your oven to 375°F (190°C). This will ensure that your frittata cooks evenly and sets perfectly.

Prepare the Ingredients

In a mixing bowl, whisk together the eggs and milk until well combined. Season with salt and pepper. If you're using cheese, you can mix it in at this stage.

Sauté the Vegetables

In an oven-safe skillet, heat the olive oil over medium heat. If using, add diced onions or bell peppers and sauté until they are soft and slightly caramelized (about 3-4 minutes). Then, add the diced tomatoes and cook for another 2-3 minutes until they begin to soften.

Add the Egg Mixture

Pour the egg mixture over the sautéed vegetables in the skillet. Sprinkle the chopped basil evenly over the top. Use a spatula to gently stir the ingredients, ensuring that the tomatoes and basil are evenly distributed throughout the eggs.

Cook on the Stovetop

Cook on the stovetop for about 3-5 minutes, or until the edges start to set. You can occasionally lift the edges of the frittata with a spatula to allow the uncooked eggs to flow underneath.

Transfer to the Oven

Once the edges are set, transfer the skillet to the preheated oven. Bake for 10-15 minutes, or until the center is set and the top is lightly golden.

Cool and Serve

Remove the frittata from the oven and let it cool for about 5 minutes. Slice into wedges and serve warm or at room temperature.

Variations

Cheese: Feel free to experiment with different types of cheese such as mozzarella, goat cheese, or feta.

Vegetable Add-ins: Consider adding spinach, zucchini, or mushrooms for additional flavor and nutrition.

Herbs: Fresh herbs like parsley or chives can enhance the frittata’s flavor.
