Step‑by‑Step Instructions for Grilled Flank Steak Pinwheels
Step 1: Butterfly the Flank Steak
Begin by placing the flank steak on a clean cutting board. With a sharp knife, make a horizontal cut across the grain of the meat, stopping about an inch from the edge. Open the steak like a book and gently pound it to an even thickness of about ½ inch using a meat mallet. This process ensures the steak remains tender as it cooks.
Step 2: Season the Meat
Evenly sprinkle 1 teaspoon of kosher salt and ½ teaspoon of freshly ground black pepper over the surface of the butterflied flank steak. Use your fingers to gently press the seasoning into the meat, ensuring an even distribution. This step will boost the flavors in your grilled flank steak pinwheels as they cook.
Step 3: Add Filling
Layer the bottom half of the butterflied steak with slices of provolone cheese, covering it completely. Next, add a generous layer of fresh spinach over the cheese, creating a vibrant, green bed. Take care to leave a small border around the edges—this will help keep the filling inside as you roll the steak.
Step 4: Roll the Steak
Starting from one end, tightly roll the steak toward the other end while securing the filling inside. As you roll, maintain a firm grip to keep the filling intact. Once rolled, insert wooden skewers through the seam every 1 to 2 inches to hold the pinwheel shape together during cooking.
Step 5: Prepare for Grilling
Brush the outer surface of the rolled pinwheels generously with olive oil to enhance moisture and prevent sticking. Sprinkle the remaining salt and pepper on the outside of the pinwheels for added flavor. Use a sharp knife to cut between the skewers, creating individual pinwheels roughly 2 inches thick, ready to hit the grill.
Step 6: Grill to Perfection
Preheat your grill to medium-high heat, ensuring it’s hot enough to create a nice sear. Place the pinwheels on the grill and cook for about 4 minutes on each side. Aim for a nice char and check that the internal temperature reaches 135°F for medium doneness. After grilling, let the pinwheels rest for 5 minutes to lock in the juices before serving.

Grilled Flank Steak Pinwheels Recipe FAQs
What type of flank steak should I use?
I recommend choosing flank steak for its rich flavor and tenderness. You can also use skirt steak or other thin cuts of beef if flank steak isn’t available. Look for a piece that has a nice marbling of fat, which adds flavor and moisture during grilling.
How should I store leftover pinwheels?
Leftovers can be stored in an airtight container in the refrigerator for up to 4 days. To maximize freshness, ensure they are completely cool before sealing. It’s a simple way to keep those delicious grilled flank steak pinwheels ready for a quick meal!

Absolutely! To freeze, wrap the uncooked pinwheels tightly in plastic wrap, followed by a layer of aluminum foil. They’ll keep well in the freezer for up to 3 months. When you’re ready to cook, simply thaw in the refrigerator overnight before grilling.
What can I do if my pinwheels are falling apart while grilling?
To avoid this, ensure you’re inserting skewers well—about every 1 to 2 inches—while rolling the steak. Also, make sure the filling is tightly packed. If they still come apart, try using butcher’s twine to tie the pinwheels for extra security, which can also enhance presentation!
Are there any dietary considerations for this recipe?
For those with dairy allergies, you can substitute provolone cheese with dairy-free cheese alternatives or even skip the cheese entirely for a leaner option. Additionally, if you’re serving these to pets, it’s best to avoid offering them any cooked seasoned meats, as some ingredients like garlic and onion can be harmful to them.
Can I prepare the pinwheels ahead of time?
