Ingredients

• 1 pound skirt steak
• 2 tablespoons olive oil
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 2 large yellow onions
• 2 tablespoons unsalted butter
• 3 tablespoons balsamic vinegar
• 2 tablespoons brown sugar
• 2 cloves garlic
• 1 teaspoon fresh thyme leaves
• 1 tablespoon vegetable oil

Directions

Step 1

Take the skirt steak out of the refrigerator and let it come to room temperature for about 20 minutes. This ensures even cooking.

Step 2

Season the steak generously with salt and black pepper on both sides. Set aside.

Step 3

Peel and thinly slice the yellow onions into uniform half-moons. Mince the garlic cloves finely.

Step 4

In a medium skillet, melt the unsalted butter over medium heat. Once melted, add the sliced onions and a pinch of salt, stirring to coat them in the butter.

Step 5

Reduce the heat to low and cook the onions, stirring occasionally, until they soften and caramelize deeply—this will take about 15–20 minutes.

Step 6

Once the onions are caramelized, stir in the balsamic vinegar, brown sugar, minced garlic, and thyme leaves. Let the mixture simmer for 5 minutes, allowing the flavors to meld and the marmalade to thicken slightly. Remove from heat and set aside.

Step 7

Heat a large cast-iron skillet or grill pan over high heat. Add the vegetable oil and swirl to coat the surface.

Step 8

Once the skillet is very hot, add the skirt steak. Cook for 3–4 minutes on each side for medium-rare, or longer for your desired doneness.

Step 9

Transfer the cooked steak to a cutting board and let it rest for 5 minutes to retain the juices.

Step 10

Slice the steak against the grain into thin strips and serve with a generous scoop of onion marmalade on top. Pair with your favorite sides like mashed potatoes or a fresh green salad.
