How to Make Caramelized Onion Frittata

Step 1: Caramelize the Onions

Start by slicing the yellow onions thinly. Heat olive oil in a skillet over medium-low heat and add the onions. Stir occasionally, cooking gently to coax out their natural sweetness until they turn golden brown and soft. This process takes patience but rewards you with deep, rich flavor.

Step 2: Prepare the Egg Mixture

While the onions cook, whisk the eggs in a bowl until smooth and slightly frothy. Stir in freshly chopped herbs, salt, pepper, and the plant-based cheese (plant-based) for a creamy, aromatic base.

Step 3: Combine and Cook

Once the onions are perfectly caramelized, spread them evenly in the skillet. Pour the egg mixture on top, allowing it to settle around the onions. Cook over low-medium heat without stirring, letting the eggs set gradually along the edges while remaining tender in the center.

Step 4: Finish Under the Oven

Transfer the skillet to a preheated oven and bake for about 8-10 minutes, or until the frittata is fully set and lightly golden on top. This final step ensures even cooking and a delightfully light texture.

Step 5: Serve and Enjoy

Let the frittata cool slightly before slicing. This allows it to firm up for clean, perfect pieces every time. Garnish with extra herbs, and dig in!

Pro Tips for Making Caramelized Onion Frittata

• Low and slow caramelization: Cook onions on low heat to avoid burning and develop the richest sweetness.
• Use a well-seasoned skillet: To prevent sticking and help the frittata cook evenly.
• Whisk eggs thoroughly: Incorporate air for a lighter, fluffier texture.
• Don’t rush baking: Ensure the frittata finishes cooking gently in the oven for the best consistency.
• Allow to rest before slicing: Helps the frittata to set and makes serving easier.
