This tortilla offers a delightful and wholesome take on a classic Spanish dish. Instead of potatoes, thinly sliced rutabaga creates a hearty base, providing a subtly sweet and earthy flavor that complements the other ingredients beautifully. The rutabaga slices are gently simmered in olive oil until tender, allowing them to absorb the rich, fruity notes of the oil.

This slow cooking process coaxes out their natural sweetness, creating a foundation of flavor for the entire dish. Caramelized onions, layered generously over the softened rutabaga, introduce a contrasting sweetness and depth. These onions, slowly cooked to a golden-brown perfection, offer a savory counterpoint to the rutabaga's mildness.

The gentle caramelization process enhances their inherent sugars, resulting in a luscious, almost jam-like texture that melts in your mouth. The sweetness of the onions perfectly balances the earthiness of the rutabaga. Beaten eggs are then poured over the rutabaga and onion mixture, binding everything together into a cohesive and satisfying whole.

The eggs cook to a custardy consistency, adding a creamy richness to the tortilla. Initially cooked on the stovetop to achieve a beautifully browned and slightly crisp bottom, the tortilla is then transferred to the oven to finish cooking through. This two-stage cooking process ensures that the tortilla is cooked evenly, with a perfectly set interior and a golden-brown exterior.

Once cooked, the tortilla is carefully flipped onto a serving platter, revealing its attractive, golden-brown surface. Sliced into wedges, it makes an impressive and satisfying dish, perfect for brunch, lunch, or a light dinner. Each bite offers a harmonious blend of textures and flavors: the tender rutabaga, the sweet caramelized onions, and the creamy eggs, all infused with the rich aroma of olive oil.

This tortilla is a testament to simple ingredients transformed into something truly special, a Mediterranean-inspired delight that is both comforting and flavorful.
