Step-by-Step Instructions

1. 1.Marinate the Ground Beef

   In a bowl, combine 500g ground beef with 1 tsp garlic powder, 1/2 cup finely chopped white onions, 1 tsp salt, 1/2 tsp black pepper, and 1 tbsp Knorr Liquid Seasoning. Mix thoroughly with your hands until all ingredients are well incorporated. Cover the bowl with cling wrap and let it rest in the fridge overnight to allow the flavors to sink in.

2. 2.Caramelize the Onions for the Sauce

   Melt 50g butter in a pan over low heat. Add 1 cup finely chopped white onions to the pan. Cook the onions low and slow, stirring occasionally, until they turn golden brown and become sweet and caramelized. This process should take about 15-20 minutes. Once done, set the caramelized onions aside to cool completely.

3. 3.Prepare the Burger Sauce

   In a clean bowl, combine 1 cup mayonnaise, 2 tbsp Sriracha hot chili sauce, 2 tbsp yellow mustard, 2 tbsp sweet pickle relish, 1/4 cup all-purpose cream, and the cooled caramelized onions. Mix all ingredients well until you have a smooth and creamy sauce. Transfer the burger sauce into a squeeze bottle for easy drizzling later.

4. 4.Cook the Marinated Beef

   Using the same pan where you caramelized the onions (with the leftover butter), add the marinated ground beef. Break up the beef with a wooden spoon and cook over medium heat, browning it well until it's fully cooked and no pink remains. This should take approximately 10-15 minutes. Once cooked, remove the beef from the pan and set it aside.

5. 5.Warm the Tortilla Wraps

   In the same pan, warm the soft tortilla wraps one by one over medium heat for about 1-2 minutes per side, until they are soft and pliable with slight char marks. This makes them easier to fold and enhances their flavor.

6. 6.Assemble the Burger Tacos

   To assemble your burger tacos, take a warm tortilla wrap and layer it with shredded romaine lettuce. Add a generous amount of grated cheese, followed by the juicy cooked ground beef. Finally, drizzle a generous amount of the creamy, tangy burger sauce on top. Fold or roll the taco as desired and serve immediately.
