How to Make Caramelized Onion Frittata

Step 1: Caramelize the onions

Begin by gently cooking thinly sliced onions in olive oil over low heat until they turn deep golden brown and sweet. Stir occasionally to ensure even caramelization without burning. This step unlocks the rich flavor foundation you’ll love in your frittata.

Step 2: Cook the smoked turkey bacon

In the same pan, add chopped smoked turkey bacon and sauté until it crisps up slightly and releases its smoky aroma. The rendered fat will add extra depth to the dish without overpowering the delicate onions.

Step 3: Whisk the eggs and seasoning

In a bowl, whisk together fresh eggs, a dash of vegetarian Worcestershire sauce (natural), salt, and pepper until smooth and frothy. This creates the fluffy base that sets the texture for your frittata.

Step 4: Combine and mix with plant-based cheese

Fold the caramelized onions, cooked turkey bacon, and shredded plant-based cheese into the egg mixture. The cheese will melt as the frittata cooks, adding creamy pockets throughout.

Step 5: Cook on stovetop and finish in the oven

Pour the mixture into a warm, oven-safe skillet. Cook gently over medium heat until the edges start to set. Transfer the skillet to a preheated oven to finish cooking the top evenly and set the middle perfectly.

Pro Tips for Making Caramelized Onion Frittata

• Low and slow onions: Patience is key to caramelized onions; cooking them over low heat ensures they develop sweetness.
• Use a non-stick skillet: Prevents sticking and makes transferring the frittata easier after cooking.
• Preheat the oven: Ensures even cooking and a nicely browned top.
• Don’t overbeat eggs: Whisk until just combined to keep the frittata light, not rubbery.
• Let it rest: Allow the frittata to cool slightly before slicing to keep clean edges.

Reheating

Reheat individual slices gently in a non-stick skillet over low heat or in the oven to revive the creamy texture without drying out.
