How to Make Fried Onion Strip Beef Sandwich
-
Soak onions: Cut the onion into thin strips and soak them in buttermilk for at least 30 minutes. This step infuses tenderness and flavor into the onions for frying.
-
Mix dry ingredients: In a bowl, combine the all-purpose flour, kosher salt, smoked paprika, garlic powder, and cayenne pepper. This seasoned flour will create a crunchy coating for the fried onions.
-
Heat oil: Heat vegetable oil in a frying pan over medium heat. Ensure the oil is hot enough (around 350°F) for frying to achieve that golden, crispy texture.
-
Dredge onions: Remove the soaked onion strips from the buttermilk, dredge them in the seasoned flour mixture, and gently shake off excess flour. Then, fry until golden brown, which will take about 3-4 minutes.
-
Prepare beef patties: Season the ground beef with salt, pepper, onion powder, and garlic powder. Form the seasoned beef into patties, ensuring they are evenly shaped for consistent cooking.
-
Cook patties: Cook the patties on a skillet over medium-high heat until they reach your desired doneness, approximately 4-5 minutes per side for medium. The internal temperature should be 160°F.
-
Add toppings: Once cooked, top each patty with steak sauce, mayonnaise, and a slice of Provolone cheese. Allow the cheese to melt slightly on the hot patties for maximum flavor!
-
Toast buns: In another pan, toast the brioche buns in unsalted butter until golden brown. This adds a rich flavor and a delightful crispy element to the sandwich.
-
Assemble sandwiches: Layer the cooked patties onto the toasted brioche buns and finish off by adding a generous handful of the crispy fried onion strips.
Optional: Serve with a side of fries or a fresh salad for a complete meal!

Expert Tips for the Smoked Steakhouse Burger
-
Onion Preparation: Soak the onions: Ensure they soak long enough in buttermilk (30 minutes) to achieve that soft, flavorful texture before frying.
-
Perfect Frying: Monitor oil temperature: Use a thermometer to keep the oil around 350°F for perfectly crispy fried onion strips. Too hot, and they’ll burn; too cool, and they’ll absorb oil.
-
Beef Patty Consistency: Shape carefully: Make sure to form the beef patties evenly to ensure consistent cooking and juiciness throughout each Smoked Steakhouse Burger.
-
Cheese Melting: Cover while cooking: Place a lid on the skillet for the last minute of cooking to help the Provolone cheese melt perfectly over the hot beef patties.
-
Bun Toasting: Don’t rush the toast: Take your time to toast the brioche buns in butter until golden; this step adds a beautiful flavor and texture to the sandwich.
-
Custom Toppings: Experiment with flavors: Feel free to add jalapeños, avocado, or your favorite sauce to customize the sandwich to your taste!
