Ideal for those seeking a nutritious, low-carb, and high-protein addition to their meals, these cabbage steaks offer a tender texture with delightfully crisp edges. They serve as an excellent accompaniment to grilled meats or can stand alone as a satisfying vegetarian option.
The creation of these exquisite cabbage steaks begins with a simple yet effective preparation. A medium head of green cabbage is carefully trimmed and sliced into four substantial 1-inch thick "steaks." These slices are then arranged on a foil-lined baking sheet, brushed with a generous coating of extra-virgin olive oil, and seasoned with ground pepper and salt. The cabbage steaks are then placed in a preheated oven at 425°F, positioned on the lower third rack. They undergo a transformation through roasting for approximately 45 minutes, with a single flip midway, until they achieve a beautiful golden-brown hue and a tender consistency.
While the cabbage roasts, the French onion butter, a cornerstone of this dish's rich flavor, is meticulously prepared. In a medium skillet over medium heat, one tablespoon of unsalted butter is melted. Thinly sliced yellow onion is added and gently cooked until it softens, a process that takes about five minutes. Following this, two-thirds of a cup of lower-sodium beef broth, minced garlic, and chopped fresh thyme are introduced to the skillet. This mixture is simmered, with occasional stirring, until the onions are deeply caramelized and all the broth has been absorbed, typically spanning 10 to 15 minutes. To further enhance the flavor profile, one tablespoon of sherry vinegar and one teaspoon of reduced-sodium Worcestershire sauce are stirred in and cooked until mostly evaporated, which takes about one minute. The onion mixture is then removed from the heat and allowed to cool for ten minutes.
The cooled onion mixture is then transferred to a mini food processor. The remaining four tablespoons of softened unsalted butter, along with half a teaspoon of salt and a quarter teaspoon of pepper, are added. The mixture is processed until it reaches a mostly smooth consistency, requiring one to two minutes, with occasional scraping of the sides to ensure even blending. This yields a rich, flavorful French onion butter.
Finally, the roasted cabbage steaks are ready for their finishing touch. Each tender cabbage steak is generously topped with one tablespoon of the freshly prepared French onion butter and three tablespoons of finely grated Gruyère cheese. For an added touch of elegance and flavor, an extra sprinkle of fresh thyme can be used as a garnish. Any leftover onion butter can be refrigerated in an airtight container for up to three days, ready to be used in other culinary creations after softening at room temperature for 15 minutes.
This innovative dish transforms cabbage into a star, combining it with the classic, comforting flavors of French onion soup. The result is a savory, wholesome, and incredibly satisfying meal that can elevate any dinner table. Its simplicity in preparation belies its complex and rich taste, making it a perfect choice for both everyday meals and special occasions.
