Ingredients

Scale

6 large eggs

1/4 cup milk or cream

1 tbsp olive oil or butter

1 medium onion, thinly sliced

1 apple, thinly sliced (sweet or tart variety)

1/2 cup shredded Gruyère or Swiss cheese

1 tsp chopped fresh sage or thyme

Salt and black pepper to taste

Instructions

Preheat oven broiler. In a bowl, whisk eggs, milk, salt, pepper, and herbs. Set aside.

Caramelize Onions & Apples: In an oven-safe skillet, heat oil over medium. Add onions and cook slowly until golden and soft, about 10 minutes. Add apple slices and cook 3–5 minutes more, until slightly tender.

Pour & Cook: Reduce heat to low. Spread the onion-apple mixture evenly. Pour egg mixture over and sprinkle with cheese. Cook without stirring until the edges begin to set, about 5–6 minutes.

Broil to Finish: Transfer skillet to the oven and broil for 2–3 minutes, until the top is puffed and golden.

Rest & Serve: Let sit for 5 minutes before slicing.
