- 1 1/2 pounds flank steak, butterflied and pounded to 1/4-inch thickness: The perfect cut for rolling, tender and flavorful when cooked medium-rare.
- 2 tablespoons olive oil, divided: Adds richness and helps achieve a beautiful sear on both the onions and steak.
- 2 large yellow onions, thinly sliced: Slowly caramelized to bring out their natural sweetness and depth.
- 2 cloves garlic, minced: Fresh garlic gives a subtle pungency that enhances the savory profile.
- 1 teaspoon fresh thyme leaves: Offers a delicate herbal note that pairs beautifully with beef.
- 1/2 teaspoon salt: Balances and intensifies the flavors throughout the recipe.
- 1/2 teaspoon black pepper: Adds a gentle heat and aromatic touch.
- 1 tablespoon Worcestershire sauce: Provides umami richness and depth to the caramelized onion mixture.
- 1/2 cup beef broth: Helps to deglaze the pan and create a luscious, jammy sauce for the onions.
- 1 cup shredded Gruyère cheese: Melts beautifully to add a nutty, slightly sweet creaminess.
- 1/2 cup shredded mozzarella cheese: Gives that stretchy, gooey factor we all love in cheesy dishes.
- 1 tablespoon fresh parsley, chopped: For a fresh, vibrant garnish finishing touch.
How to Make French Onion Steak Pinwheels Recipe
Step 1: Caramelize the Onions
Start by heating one tablespoon of olive oil in a large skillet over medium heat. Add the thinly sliced onions and cook them slowly, stirring occasionally for about 15 to 20 minutes. Patience here is key because those onions need to soften and turn a rich golden brown to develop that deep caramelized sweetness that sets this dish apart.
Step 2: Spice It Up
Once the onions have reached that perfect caramelized stage, stir in the minced garlic, fresh thyme leaves, salt, and black pepper. Cook for another minute to let all those fragrant aromas come together before adding a splash of Worcestershire sauce and beef broth. Let the mixture simmer until the liquid reduces and the onions form a thick, jammy consistency. Then, remove from the heat and let it cool just a bit.
Step 3: Prepare the Steak
Lay your butterflied and pounded flank steak flat on a sturdy cutting board. Brush the entire surface with the remaining tablespoon of olive oil—this helps both with flavor and getting a nice sear later on.
Step 4: Assemble the Pinwheels
Spread the luscious caramelized onion mixture evenly over the steak, making sure every inch is covered with that jammy goodness. Then sprinkle the shredded Gruyère and mozzarella cheese over the onions. Starting from the long side, roll the steak tightly into a log shape. Secure it with kitchen twine at one-inch intervals; this step keeps your pinwheels intact when cooking and slicing.
Step 5: Slice and Sear
For cleaner slices, refrigerate the rolled steak for about 20 minutes before cutting. Then slice into pinwheels approximately 1 1/2 inches thick. Heat a skillet or grill pan over medium-high and sear the pinwheels for 3 to 4 minutes per side. Aim for an internal temperature of around 130°F for that perfect medium-rare finish. Let the pinwheels rest for five minutes once done to let those juices redistribute.
How to Serve French Onion Steak Pinwheels Recipe

Garnishes
A sprinkle of fresh parsley over the top brightens the dish visually and adds a subtle herbaceous note that welcomes each bite. If you want to be a little extra, a drizzle of balsamic glaze can complement the sweetness of the onions beautifully.
Side Dishes
French Onion Steak Pinwheels Recipe pairs wonderfully with creamy mashed potatoes or a light mixed green salad tossed in vinaigrette. For something a bit heartier, roasted root vegetables or steamed asparagus rounds out the plate with color and texture.
Creative Ways to Present
If you’re serving at a party or want a dramatic presentation, arrange the pinwheels in a circular pattern on a large platter and garnish with fresh herbs and edible flowers. You could also serve them alongside dipping sauces like a horseradish cream or a rich red wine jus for guests to customize each bite.
Make Ahead and Storage
Storing Leftovers
Wrap leftover pinwheels tightly in plastic wrap or store them in an airtight container in the refrigerator for up to 3 days. This way, you can enjoy those rich flavors without having to cook again.
Freezing
You can freeze the pinwheels before cooking by wrapping them well in plastic wrap and then aluminum foil to prevent freezer burn. They’ll keep nicely for up to 2 months. When you’re ready to eat, thaw overnight in the fridge.
Reheating
Reheat leftovers gently in a skillet over medium-low heat so the cheese melts without overcooking the steak. Alternatively, warm them in a 350°F oven covered with foil for about 15 minutes to preserve juiciness.
FAQs
Can I use a different cut of steak for this recipe?
Flank steak is ideal because it’s thin and easy to roll, but you could try skirt steak or a thinly sliced sirloin. Just watch the cooking time to avoid toughness.
Is there a vegetarian version of French Onion Steak Pinwheels?
Absolutely! Swap steak for large portobello mushroom caps or thin slices of eggplant and use vegetable broth instead of beef broth. The caramelized onions and cheese will still shine beautifully.
How do I know when the pinwheels are perfectly cooked?
Using a meat thermometer is the best way to check; aim for an internal temperature of 130°F for medium-rare. The exterior should be browned and slightly crisp while the inside stays tender and juicy.
Can I prepare the onions ahead of time?
Yes, caramelized onions can be made up to two days in advance and stored in the refrigerator. This actually saves a lot of time on the day you’re cooking the pinwheels.
What can I substitute if I don’t have Gruyère cheese?
Provolone or Swiss cheese both melt well and provide a similar nutty and creamy flavor that complements the onions and steak nicely.
