Smoked Meatloaf That Tastes Like an In-N-Out Burger
How to Make Smoked Meatloaf with In-N-Out Burger Flavor
This smoked meatloaf delivers the nostalgic comfort of an In-N-Out burger inside a homemade loaf. Start by turning a hamburger bun into breadcrumbs—toast and crumble until dry, then mix with finely diced onions and milk. Combine with ground beef, yellow mustard, ketchup, kosher salt, black pepper, Worcestershire sauce, and an egg. Gently mix the ingredients and shape them into a loaf on a parchment-lined baking sheet.
Preheat your pellet grill to 275°F and place the meatloaf onto the smoker. Let it cook for about an hour, then prepare your classic burger toppings.
Creating Signature Sauce and Toppings
While the meatloaf smokes, slowly grill onions until soft and golden. As the internal temperature nears 155°F, spread a layer of In-N-Out burger sauce on top. If you do not have the restaurant version, mix ketchup, mayonnaise, apple cider vinegar, and pickle relish at home.
Continue smoking the meatloaf for another 20 to 25 minutes. Before finishing, add slices of American cheese and top with the grilled onions. Allow the meatloaf to cook a final five minutes, letting the cheese melt and the flavors combine.
Slicing and Serving Smoked Meatloaf
After removing the meatloaf from the smoker, let it rest briefly before slicing. Each serving should feature a juicy interior crowned with melted cheese and onions. Serve with oven or air-fried potatoes, or a favorite side that matches classic burger fare.
