Ingredients
- 1 (2-pound) flank steak

- 1 cup fresh spinach, chopped
- 1 cup mushrooms, diced
- 1 onion, finely chopped
- 2 cloves garlic, minced
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon dried thyme
- 1/2 cup grated Parmesan cheese
- 1/4 cup breadcrumbs

Directions
Prepare the Filling
- In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the onion and garlic, and sauté until the onion is translucent, about 5 minutes.
- Add the mushrooms and cook until softened, approximately 4 minutes.
- Stir in the spinach, cooking until wilted, about 2 minutes. Season with salt, pepper, and thyme. Remove from heat and let cool slightly.
- Mix in the Parmesan cheese and breadcrumbs, stirring until well combined.
Stuff the Flank Steak
- Preheat your oven to 375°F (190°C).
- Lay the flank steak flat on a cutting board and gently pound to an even thickness if necessary.
- Spread the mushroom and spinach mixture evenly over the steak, leaving a small border around the edges.
- Roll the steak tightly from one end to the other and secure it with kitchen twine or toothpicks.

Cook the Steak
- Heat the remaining tablespoon of olive oil in a large ovenproof skillet over medium-high heat. Sear the rolled steak on all sides until browned, about 8 minutes total.
- Transfer the skillet to the preheated oven and roast for 25-30 minutes, or until the internal temperature reaches 135°F (57°C) for medium-rare.
- Remove from the oven and let rest for 5 minutes before slicing.
Notes
- For best results, allow the steak to marinate in olive oil, salt, and pepper for a few hours before cooking. Learn more about marinating here.
- Ensure your knife is sharp when slicing the steak to prevent tearing the meat.
- Try using fresh herbs for a more robust flavor. Read about the benefits of fresh herbs here.
Variations

FAQ
- Can I prepare this dish ahead of time?
You can prepare the stuffing and stuff the steak a day ahead. Store it in the refrigerator and bring it to room temperature before cooking. - What if I don’t have an ovenproof skillet?
After searing, transfer the steak to a baking dish for roasting. - How do I know when the steak is done?
Use a meat thermometer to check that the internal temperature reaches 135°F (57°C) for medium-rare.
