How to Make Caramelized Onion Frittata

Step 1: Caramelize the Onions

Begin by heating olive oil in a frying pan over medium-low heat. Add thinly sliced onions and a pinch of salt. Cook slowly, stirring occasionally, until the onions turn a rich golden brown and develop a sweet, soft texture. This process can take up to 30 minutes but is essential for that signature depth of flavor.

Step 2: Cook the Smoky Turkey Bacon

In a separate pan, cook the smoky turkey bacon until crisp. Remove and set aside on paper towels to drain excess oil. Once cool, chop into bite-sized pieces that will evenly distribute through the frittata.

Step 3: Prepare the Egg Mixture

Crack eggs into a mixing bowl, season with salt, pepper, and a splash of vegetarian Worcestershire sauce (natural). Whisk well until fluffy and combined. Stir in the plant-based cheese and fresh herbs gently to keep the mixture light and airy.

Step 4: Combine and Cook

Reduce heat to medium. Add the caramelized onions and turkey bacon into the eggs, folding them in gently. Pour the entire mixture back into the pan, spreading evenly. Allow to cook without stirring until the edges set and the center is still slightly runny.

Step 5: Finish in the Oven

Transfer the pan to a preheated oven at 350°F (175°C). Bake for 8-10 minutes until the frittata is fully set and lightly golden on top. Remove and let cool slightly before slicing and serving.

Pro Tips for Making Caramelized Onion Frittata

• Take Your Time on Onions: Slow cooking is key to unlocking their natural sweetness and avoiding bitterness.
• Use a Non-stick or Oven-Safe Pan: This ensures easy flipping or transferring to the oven without breaking the frittata.
• Don’t Overmix Eggs: Whisk just enough to combine, so the texture stays tender and fluffy.
• Check Oven Temperature: A moderate oven allows gentle cooking and prevents over-browning.
• Let It Rest Before Cutting: This helps the frittata hold together perfectly when sliced.
