This delicious stuffed baked steak recipe turns a trimmed 1½- to 2-pound flank steak into an impressive dinner filled with mushrooms, onion, garlic, spinach, mozzarella, and Parmesan. Season the steak, roll it tightly, sear it for extra browning, and bake it at 375°F (190°C) for about 20–30 minutes, followed by a 10-minute rest.
Every slice delivers savory beef, tender vegetables, creamy melted cheese, and flavorful pan juices. The method is easy enough for a weeknight yet attractive enough for guests, and cutting the finished roll across the grain gives you tender, beautiful rounds that pair wonderfully with potatoes, vegetables, or a crisp green salad.

Stuffed baked steak looks like a special-occasion centerpiece, but the preparation is wonderfully practical. A single flank steak serves four to six people, and the filling uses familiar ingredients that become deeply savory after a quick sauté.
The contrast is especially satisfying: browned beef surrounds soft spinach, earthy mushrooms, sweet onion, fragrant garlic, and bubbling cheese. Searing the roll first creates a delicious crust, while baking gently finishes the center without requiring a complicated sauce.
This dinner also gives you flexibility. Serve generous slices with mashed potatoes for a cozy meal, roasted vegetables for a colorful plate, or a crisp salad when you want something lighter.

Ingredients You’ll Need
The star is flank steak, a long, flavorful cut that becomes easier to roll after it is butterflied and pounded evenly. Ask your butcher to butterfly it if you prefer, or carefully open the steak horizontally with a sharp knife.
- Beef: Choose a trimmed flank steak weighing about 1½–2 pounds.
- Vegetables: Onion, mushrooms, garlic, and baby spinach create a savory, colorful filling.
- Cheese: Mozzarella or provolone melts smoothly, while Parmesan adds a salty, nutty finish.
- Seasoning: Italian seasoning, kosher salt, black pepper, and optional paprika complement the beef.
- Finishing liquid: Beef broth or red wine is optional, but it helps keep drippings from scorching and creates tasty pan juices.
- Tools: Kitchen twine or wooden toothpicks hold the roll together during cooking.
Keep the filling ingredients finely chopped or sliced so the steak can roll without large pieces creating gaps. Have the twine, baking dish, and thermometer ready before you begin.

How to Make It Step-by-Step
Step 1: Heat the oven to 375°F (190°C) and lightly oil a baking dish. If the flank steak is not already butterflied, open it carefully through the side so it lays flatter, then place it between plastic wrap and pound it to an even ¼- to ½-inch thickness.
Step 2: Sprinkle both sides of the steak with the divided salt and pepper, Italian seasoning, and optional paprika. Seasoning the meat before adding the filling ensures that every slice has a balanced flavor.
Step 3: Warm the olive oil in a skillet over medium heat. Add the onion and mushrooms and cook for 5–7 minutes, stirring often, until the onion softens and the mushroom liquid has mostly evaporated.
Step 4: Stir in the minced garlic and baby spinach. Cook for 1–2 minutes, just until the garlic is fragrant and the spinach wilts, then remove the skillet from the heat and cool the mixture briefly.
Step 5: Lay the steak flat and spread the vegetable mixture over it, leaving about a 1-inch border on every side. Sprinkle the mozzarella or provolone and Parmesan evenly over the top, taking care not to pile the filling too thickly.
Step 6: Roll the steak firmly from one long side to the other. If possible, keep the grain running lengthwise as you roll, then secure the steak with kitchen twine tied every 1–2 inches or with wooden toothpicks.
Step 7: Heat an oven-safe skillet until hot and sear the rolled steak for 2–3 minutes per side. This optional step adds a richly browned exterior and more flavor to the finished pan juices.
Step 8: Add the beef broth or red wine to the skillet if using, then bake the steak uncovered for approximately 20–30 minutes. The exact time depends on the thickness of the roll and your preferred doneness, so begin checking with a thermometer before the upper end of the range.
Step 9: For the USDA-recommended minimum, cook the center to at least 145°F (63°C), followed by a rest. Transfer the steak to a cutting board and let it rest for 10 minutes so the juices settle and the cheese stays inside when sliced.
Step 10: Remove the twine or toothpicks and cut the steak across the grain into ½- to 1-inch rounds. Spoon the pan juices over the slices and serve immediately with your chosen sides.
Pro Tips for a Perfect Steak Roll
Even thickness is one of the most important details in this recipe. Thin sections can overcook while the center is still finishing, so take a few minutes to pound the steak evenly rather than relying on the original shape of the cut.
Do not rush the mushrooms. Their liquid should evaporate before the spinach and garlic go into the pan; a wet filling can make the steak difficult to secure and may cause the roll to split during baking.
- Leave a 1-inch border so the filling does not squeeze out as you roll.
- Roll firmly but do not compress the steak so tightly that the filling is forced through the sides.
- Place the seam side down while preparing the pan, then secure the roll well before searing.
- Use an instant-read thermometer rather than judging doneness by time alone.
- Rest the roll for the full 10 minutes before slicing for cleaner spirals and juicier beef.
Medium-rare can be removed at about 125–130°F and may rise to approximately 130–135°F while resting, but that is below the USDA minimum recommendation. For food safety, cook the steak to 145°F (63°C) before resting.

What to Serve with Stuffed Baked Steak
Rich stuffed steak welcomes sides that either absorb its juices or add freshness. Creamy mashed potatoes are a classic choice, especially when spooned with the broth or wine drippings from the baking dish.
Roasted carrots, green beans, asparagus, or broccoli add color and a pleasant crisp-tender contrast. A green salad with a bright vinaigrette can balance the cheese and beef without making the plate feel heavy.
For a family-style spread, consider adding a warm casserole such as our baked chicken and potato casserole. If you prefer another stuffed entrée for a varied dinner table, our beef and broccoli stuffed peppers are a colorful option.
Storage and Reheating
Cool leftover steak promptly, then store it in an airtight container in the refrigerator. It is best enjoyed within three to four days, with the slices kept alongside any remaining pan juices to help protect their moisture.
Reheat gently in a covered baking dish with a spoonful of broth or water until warmed through. Short bursts in the microwave also work, but avoid overheating because flank steak can become firm and the cheese may separate.
You can slice only what you plan to serve and keep the remaining roll intact. Larger pieces generally retain their juices better than thin slices during storage and reheating.

Ingredients
Method
- Heat the oven to 375°F (190°C) and lightly oil a baking dish. Butterfly the flank steak if needed, place it between sheets of plastic wrap, and pound it to an even ¼- to ½-inch thickness.
- Season both sides of the steak with the salt, pepper, Italian seasoning, and optional paprika. Heat the olive oil in a skillet over medium heat, then cook the onion and mushrooms for 5–7 minutes until softened and most of the moisture has evaporated.
- Add the garlic and spinach to the skillet and cook for 1–2 minutes, just until the spinach wilts. Cool the vegetable mixture briefly so it does not melt the cheese before the steak is rolled.
- Spread the filling over the steak, leaving about a 1-inch border around the edges. Sprinkle the mozzarella or provolone and Parmesan evenly over the vegetables.
- Roll the steak tightly from one long side to the other, keeping the grain running lengthwise if possible. Secure the roll with kitchen twine at 1–2-inch intervals or use wooden toothpicks.
- For better browning, sear the rolled steak in a hot oven-safe skillet for 2–3 minutes per side. Add the beef broth or red wine if using, then bake uncovered for approximately 20–30 minutes, depending on thickness and desired doneness.
- Check the center with an instant-read thermometer and cook the beef to at least 145°F (63°C) for the USDA-recommended minimum. Transfer the steak to a cutting board and let it rest for 10 minutes before removing the twine or toothpicks.
- Slice the rested steak into ½- to 1-inch rounds, cutting across the grain for more tender bites. Arrange the slices on a platter and spoon the pan juices over the top before serving.
