Cooking Steps
Before starting, wash and dry all produce. Lightly oil the grill.While you prep, preheat grill to 400°F over medium heat. Halve buns. Peel, then cut onion into 1/4-inch pieces. Drain, then finely chop 2 tbsp pickles (dbl for 4 ppl). Cut potatoes lengthwise, into 1/2-inch slices. Add potatoes, 1/2 tsp garlic salt and 1 tbsp oil (dbl both for 4 ppl) to a medium bowl. Season with pepper, then toss to coat. Combine beef and 1/4 tsp salt (dbl for 4 ppl) in a large bowl. Season with pepper. Form mixture into 2 equal-sized patties (4 patties for 4 ppl). Lightly press a thumb print halfway into each patty. (NOTE: Don't push all the way through!)
Add onions, remaining garlic salt, 1 tbsp water, 1 tbsp oil and 1/2 tsp sugar (dbl all for 4 ppl) to another medium bowl. Season with salt and pepper, then toss to coat. Layer two 12x12-inch pieces of foil. Arrange onion mixture on one side of foil. Fold foil in half over onions and pinch to seal pouch. (NOTE: Make 2 pouches for 4 ppl, using 2 sheets of foil per pouch.)
Add potatoes to one side of the grill. Close lid and grill, flipping once, until grill-marked and tender, 14-16 min. Place onions on other side of grill and cook until tender, 14-16 min.
While potatoes and onions grill, add mayo, ketchup, Dijon and chopped pickles to a small bowl. Season with pepper, then stir to combine.
When veggies have been grilling for 7-8 min, add patties to grill. (TIP: Don't overcrowd your grill! Grill patties once onions and potatoes are done if there isn't enough space on the grill.) Close lid and grill patties, flipping once, until cooked through, 4-5 min per side.** When patties are almost done, add buns to grill, cut-side down. Close lid and grill buns until warmed through, 2-3 min. (NOTE: Keep an eye on buns so that they don't burn!)
Carefully open foil pouch. Spread some secret sauce onto buns. Top bottom buns with onions, patties, remaining pickles, spring mix and top buns. Divide burgers and potatoes between plates. Serve remaining secret sauce on the side for dipping.

Review summary
Updated on Feb 2026- Flavor: The secret sauce was delicious, though some found it too salty. Consider adding spices to the meat for more flavor.
- Ease of prep: Quick and easy to prepare, with many enjoying the option to grill outdoors.
- Suggestions: Add breadcrumbs to help bind the patties. Consider toasting the buns separately to prevent sogginess from grilled onions.
- Portions: Some found the beef portion small, resulting in burgers that were disproportionate to the buns.
- Texture: For juicier burgers, use leaner ground beef; some found the current blend too fatty.
