French onion soup is a timeless comfort food that warms the soul. But have you ever thought about transforming those delicious flavors into a unique dish? Introducing French Onion Steak Pinwheels! These delectable beef pinwheels are a wonderful blend of tender meat, gooey cheese, and caramelized onions. Whether you’re hosting a holiday party or craving a hearty family dinner, this recipe is a guaranteed hit.
Before we dive into the recipe, let me tell you why these French Onion Steak Pinwheels are truly special. Picture this: succulent slices of beef marinated in vegetable oil, seasoned with kosher salt, black pepper, and garlic powder. Then, we sauté thinly sliced white onions with a delightful mix of beef broth, bourbon, brown sugar, rosemary, garlic, salt, pepper, and beef tallow until they reach golden perfection. These caramelized onions, together with Swiss cheese, become the flavorful stuffing for each pinwheel. After securing them with kitchen twine, we assemble a cheesy crust made of Gruyere, Panko breadcrumbs, melted butter, and grated Parmesan.
Now, let’s get down to the nitty-gritty of making these mouthwatering pinwheels.
How to Make French Onion Steak Pinwheels
Preheat your grill to medium-high heat (about 350F) for direct cooking. Place a cast iron skillet on the grill, allowing it to preheat for about 2 minutes.
In a large pan, melt beef tallow and add the thinly sliced white onions. Season with salt and pepper, and cook over medium heat until they become caramelized and golden brown. This process usually takes around 45-60 minutes, so be patient and give them an occasional stir to prevent burning.
Once the onions have reached their desired caramelization, add garlic and rosemary, and let them cook for an additional 2 minutes. Deglaze the skillet with bourbon and beef broth, then stir in brown sugar. Let the onions simmer until most of the liquid evaporates (approximately 3-5 minutes). At this point, remove the skillet from the grill.
Lay the skirt steak on a cutting board. If it’s too long, feel free to cut it in half. Cover the steak with parchment paper or plastic wrap, and use a heavy meat mallet to pound it until it is less than ½” thick.
In a small bowl, mix salt, pepper, and garlic. Rub the steak with oil, then season both sides with the mixture. Place a layer of sliced Swiss cheese on top of the steak, followed by a line of the caramelized onions running down the middle.
Roll the skirt steak lengthwise to create a pinwheel shape. Use cooking twine to secure it, and then slice between the two strings to create two separate pinwheels. Repeat this process with the remaining skirt steak.
Season the tops of the pinwheels with salt, pepper, and garlic.
Grilling & Serving
Preheat your grill to a two-zone high heat (around 400°F). Place the pinwheels on the hot side of the grill and sear them for 1 minute per side until a nice crust forms.
Once the pinwheels are seared, move them to the cooler side of the grill and cook indirectly until they reach an internal temperature of 125°F. This should take approximately 10-15 minutes.
After removing the pinwheels from the grill, let them rest for 10 minutes until they reach room temperature. In the meantime, prepare the cheese crust by combining all the ingredients and generously applying it to each steak. Use a torch or broil until the crust turns beautifully caramelized.
Now, it’s time to slice, serve, and savor the irresistible French Onion Steak Pinwheels!
