These slow cooker secret sauce burgers are the kind of easy, filling dinner that saves the day when the evening gets busy. Using frozen beef patties, bottled Thousand Island dressing, and a few simple pantry staples gives you tender, saucy burgers with almost no prep, and the flavor has that familiar diner-style burger taste families love. It is a cozy shortcut meal that feels a little fun and a little nostalgic, especially when everyone can build their own sandwich at the table.
Serve these burgers on soft hamburger buns with plenty of the slow-cooked sauce spooned over the top. They are especially good with oven fries, potato wedges, kettle chips, coleslaw, pickle spears, or a simple fruit salad if you want to round things out. For a casual family dinner, I like setting out sliced cheese, lettuce, tomato, and extra pickles so everyone can dress their burger just the way they like it.
Slow Cooker 5-Ingredient Secret Sauce Burgers
Servings: 6
Ingredients
6 frozen beef patties
1 cup bottled Thousand Island dressing
1 medium onion, thinly sliced
6 hamburger buns
12 pickle slices
Directions
1. Lightly coat the inside of a slow cooker with nonstick spray if desired for easier cleanup. Spread a few sliced onions on the bottom, then arrange the frozen beef patties in the slow cooker, overlapping slightly if needed.
2. Pour the bottled Thousand Island dressing evenly over the patties and top with the remaining sliced onions. Cover and cook on low for 5 to 6 hours or on high for 3 to 4 hours, until the burgers are cooked through and tender.
3. Once done, carefully separate the patties with a spatula and spoon some of the sauce and onions over each one. If you like, toast the buns for a little extra texture.
4. Place each burger on a bun, top with pickle slices, and spoon over a little extra sauce from the slow cooker. Serve hot.
Variations & Tips
Cheesy burger version: Add a slice of American or cheddar cheese to each burger right before serving. The heat from the patties will soften it nicely, and it makes the sandwich feel even more like a classic diner burger.
For picky eaters: Leave the onions off part of the batch if your family prefers a plainer burger. You can also serve the pickles and extra sauce on the side so everyone can build their own just the way they like it.
Make it a full meal: These burgers are rich and saucy, so they pair well with crispy fries, roasted potatoes, or a crunchy slaw. If you are feeding a crowd, keep the cooked patties warm in the slow cooker and let guests assemble their own sandwiches buffet-style.
Cooking tip: Since slow cookers can vary, check the burgers at the early end of the cooking time the first time you make them. If there seems to be a lot of liquid from the meat, just spoon the thicker sauce from the top over the burgers when serving for the best texture.
