Low Histamine Thyme Bison Burgers with Caramelized Onions
Burgers are one of those meals that can feel totally off-limits when you're navigating a low-histamine lifestyle, but this recipe is built from the ground up to work with your needs. Ground bison is the star here — a lean, fresh protein that's seasoned simply with fresh parsley, fresh thyme, and salt, keeping everything clean and uncomplicated. The real magic is in the caramelized onions, which cook low and slow for nearly 40 minutes until they're deeply golden and jammy, finished with just a splash of apple cider vinegar for brightness. Because the patties are made fresh and meant to be eaten the same day, you sidestep the histamine buildup that comes with leftovers or pre-made options. Serve them tucked into butter lettuce leaves for a lighter bite, or go the full route with gluten-free buns if you have them on hand. This recipe makes four satisfying servings and proves that eating carefully doesn't have to mean eating boringly.

Instructions
- 1
Heat 2 tbsp olive oil in a large skillet over medium-low heat. Add the sliced onions and 1/4 tsp salt, stirring to coat. Cook, stirring every 5 minutes, until the onions are deeply golden, jammy, and reduced to about one-quarter of their original volume, 35–40 minutes. Watch the heat — if the onions begin to brown too quickly or stick, lower the heat and add a splash of water.

Add the apple cider vinegar to the caramelized onions and stir to combine, scraping up any browned bits from the pan. Cook for 1 minute until the vinegar is absorbed, then transfer the onions to a bowl and set aside. Wipe the skillet clean.
