Chorizo Burger

1 . Stage

Start the burgers: Mix ground sirloin and chorizo together with your hands in a large bowl until well combined. Set aside to let the flavors blend while you cook the onions and make the sauce.

2 . Stage

Cook the onions: Heat oil in a large skillet over medium heat. Add onions, brown sugar, salt, and pepper; cook and stir until onions are golden brown, about 15 minutes.

3 . Stage

At the same time, make the sauce: Heat oil in a skillet over medium-high heat. Add onion and sauté until tender. Transfer onion to a blender. Add ranch dressing, red pepper, paprika, and saffron; pulse until fairly smooth. Refrigerate until needed.

4 . Stage

Finish the burgers: Preheat an outdoor grill for high heat and lightly oil the grate. Form meat mixture into four patties, slightly larger than the buns.

5 . Stage

Cook burgers on the preheated grill until well done, about 5 minutes per side. Split buns in half and spread butter on the insides. Toast briefly on the grill.

6 . Stage

Place burgers onto buns and top with caramelized onions, ranch sauce, and Manchego cheese.
