Print Recipe

A flavorful and easy recipe for loaded burger bar toppings featuring sweet, buttery caramelized onions paired with a variety of complementary ingredients to elevate any burger night.

Ingredients

Scale
  • 3 large yellow onions, thinly sliced
  • 2 tbsp unsalted butter or olive oil
  • Pinch of salt
  • Pinch of sugar
  • Sliced sharp cheddar cheese, crumbled blue cheese, or pepper jack slices (choose your favorite)
  • Dill pickle slices
  • Pickled jalapeños
  • Sliced tomatoes
  • Shredded lettuce
  • Red onion rings
  • Garlic aioli (store-bought or homemade)
  • Smoky chipotle mayo
  • Mustard (Dijon or spicy brown)
  • Crisp cooked bacon strips (optional)
  • Avocado or guacamole
  • Fresh cracked black pepper
  • Smoked paprika
  • Dash of hot sauce (optional)

Instructions

  1. Heat 2 tablespoons of butter or olive oil over medium-low heat in a large heavy-bottom skillet or cast iron pan.
  2. Add the thinly sliced onions and a pinch of salt. Stir to coat, then spread them evenly in the pan.
  3. Cook slowly, stirring every 5 minutes to prevent sticking or burning.
  4. After about 20 minutes, sprinkle a pinch of sugar to help with caramelization.
  5. Continue cooking until onions turn deep golden brown and smell sweet, about 10-15 more minutes. Taste and adjust salt if needed.
  6. While onions caramelize, slice tomatoes, red onion rings, and shred lettuce. Arrange pickles, jalapeños, and bacon strips on a platter. Prepare aioli or guacamole if making homemade.
  7. Place caramelized onions in a small bowl with a serving spoon. Arrange all other toppings in separate bowls or plates for easy access.
  8. Grill or pan-fry burger patties seasoned simply with salt and pepper. Add cheese slices on top during the last minute of cooking to melt perfectly.
  9. Toast buns lightly with a bit of butter or oil on the grill pan to prevent sogginess.
  10. Build your burger starting with the patty, then pile on caramelized onions, preferred cheeses, pickles, veggies, sauces, and bacon or avocado. Add cracked black pepper or hot sauce if desired.
  11. Enjoy immediately for the best texture and flavor contrast.

Notes

Caramelized onions can be made ahead and stored in the fridge up to 5 days; they taste even better the next day. Reheat gently before serving. Keep heat low during caramelizing to avoid burning. Toast buns lightly with butter or oil to prevent sogginess. Add cheese during the last 1-2 minutes of cooking and cover the pan briefly to melt perfectly.
