How to Make Stuffed Flank Steak with Cream Cheese, Mushrooms, Spinach, and Roasted Red Bell Pepper Recipe

Step 1: Prepare Your Grill and Flank Steak

Start by bringing your grill, like a Big Green Egg, up to 350 degrees Fahrenheit with lump charcoal or set up any grill for two-zone cooking. Meanwhile, butterfly the flank steak by cutting thinly lengthwise so it can open flat like a book. This opens the steak for stuffing and ensures a beautiful even roll when finished. Season one side with half the Killer Hogs AP Rub to establish that signature flavor base.

Step 2: Make the Cream Cheese and Veggie Filling

Spread cream cheese evenly over the seasoned steak widthwise, leaving about a one-inch border to prevent spilling. Then sauté your mushrooms in olive oil for a few minutes until tender, adding in fresh spinach to wilt it lightly. This blend delivers a wonderful mix of textures and earthiness while the roasted red bell pepper adds a subtle sweet contrast when layered on top.

Step 3: Roll and Tie the Flank Steak

Carefully roll the steak tightly, using your fingers to keep all the delicious stuffing inside. Place the rolled steak seam side down and secure with butcher’s twine, spacing the ties about one inch apart to hold everything snug during cooking. This step is essential for a neat presentation and to keep the filling intact once sliced.

Step 4: Season and Sear the Steak

Season the outside of the stuffed flank steak with the remaining Killer Hogs AP Rub and all of the Killer Hogs Steak Rub to create a flavorful crust. Place the steak on the grill and sear each side for 3 to 4 minutes. This locks in juices and forms a fantastic caramelized exterior that complements the soft, creamy stuffing inside.

Step 5: Indirect Cooking and Resting

After searing, move the flank steak to the indirect heat zone of your grill and insert a probe thermometer into the center, setting it to alert at 130 degrees Fahrenheit for a perfect medium-rare doneness. Once the target temperature is reached, remove the steak and let it rest for 10 to 15 minutes. Resting allows the juices to redistribute, ensuring every slice stays juicy and tender.

Step 6: Slice and Serve

Slice the stuffed flank steak into one-inch thick medallions to showcase the gorgeous spiral of filling inside. These slices are as stunning to look at as they are delicious to eat, making it perfect for sharing around the table.

Garnishes

Enhance the presentation by garnishing your stuffed flank steak with fresh herbs like parsley or thyme. A drizzle of balsamic glaze or a light sprinkle of flaky sea salt can add a touch of sophistication and extra flavor punch right before serving.

Side Dishes

This rich and hearty steak pairs wonderfully with simple sides to balance the complexity. Consider creamy mashed potatoes, roasted seasonal vegetables, or a crisp garden salad with a zesty vinaigrette. The colors and textures complement the stuffed flank steak perfectly, creating a harmonious plate.

Creative Ways to Present

For a dinner party, serve the medallions on a large wooden board with colorful accompaniments arranged artistically around. Alternatively, stack slices over a bed of garlic butter sautéed greens or creamy polenta for an elegant presentation that impresses without fuss.

Make Ahead and Storage

Storing Leftovers

Leftover stuffed flank steak keeps beautifully in the refrigerator for up to 3 days. Wrap tightly in foil or place in an airtight container to maintain moisture and prevent the filling from drying out.

Freezing

If you want to prep in advance, you can freeze the cooked steak wrapped securely in plastic wrap and foil for up to 2 months. Thaw overnight in the fridge before reheating for best texture and flavor preservation.

Reheating

To reheat, wrap the steak slices in foil and warm gently in the oven at 300 degrees Fahrenheit until heated through. This method keeps the steak tender and creamy inside without overcooking the exterior.

FAQs

Can I use a different cut of steak for this recipe?

While flank steak is ideal due to its thin, flat shape perfect for rolling, you could experiment with skirt steak or flat iron steak. Just ensure the cut is thin enough to butterfly and roll comfortably.

Is it necessary to use both Killer Hogs rubs?

The combination of the Killer Hogs AP Rub and Steak Rub builds a complex, layered flavor with a wonderful spice balance. However, you can substitute your favorite steak seasoning if preferred.

Can this recipe be cooked indoors?

Absolutely! Instead of a grill, you can use a large cast iron skillet to sear and finish the steak in the oven at 350 degrees Fahrenheit. Just monitor the internal temperature carefully for best results.

What is the best way to butterfly the flank steak?

Use a sharp knife to cut horizontally through the thickest part of the steak, opening it like a book without slicing all the way through. This creates a larger surface for stuffing and an even roll.

Can I prepare the filling in advance?

Yes, you can sauté the mushrooms and spinach and have the cream cheese ready ahead of time. Assemble the steak just before cooking to keep everything fresh and prevent the spinach from releasing too much moisture.
