Fire up the grill for Avocado Sprouts California Cheeseburgers with Shallot Mayo — a fresh, flavorful take on the classic burger that’s perfect for BBQs, picnics, and backyard gatherings. These burgers combine juicy, simply seasoned patties with creamy avocado, crunchy sprouts, bright tomato and spinach, and a tangy shallot mayo that brings everything together.
The patties are lightly seasoned so the toppings shine. Melted provolone adds a mild cheese note while the avocado and sprouts give the sandwich a crisp, fresh texture. The homemade shallot mayo adds a savory, slightly sweet tang that lifts every bite. Simple to prepare and made for sharing, these burgers are crowd-pleasers.
This recipe grew out of a craving for bright, fresh vegetables on a burger. Instead of piling on heavy toppings, the focus here is on fresh flavor and satisfying textures. Use good-quality ground beef and fresh ingredients for the best results. If you prefer bolder seasoning, feel free to adjust the spices in the patties.
Assemble the burger by starting with a toasted bottom bun, add the hot patty with melted provolone, then layer spinach, tomato slices, avocado, broccoli sprouts (or your favorite sprouts), and chopped cilantro. Spread a generous amount of shallot mayo on the top bun, close the sandwich, and serve immediately.
If you’re planning a BBQ, consider pairing these burgers with a creamy pasta salad, grilled asparagus, or a bright cocktail to complement the fresh flavors.
