🛒 Ingredients

🌮 For the Tacos:

• 1 lb ground beef (80% lean, 20% fat for maximum flavor)
• 10 mini taco shells or small tortillas
• 10 slices cheddar cheese
• 1 cup chopped lettuce 🥬
• Salt to taste

🥣 For the In-N-Out Style Sauce:

• 1 cup mayonnaise
• 4 tbsp ketchup
• 1 tbsp Dijon mustard
• 1 tbsp Worcestershire sauce
• 1 tsp vinegar
• 3 tbsp sweet relish
• 3 tbsp caramelized onions 🧅
• 1 tsp black pepper
• 1 tsp garlic powder
• Salt to taste

👨‍🍳 Step-by-Step Instructions

🥄 1. Make the Signature Sauce

In a medium bowl, combine: mayonnaise, ketchup, Dijon mustard, Worcestershire sauce, vinegar, sweet relish, and caramelized onions.

Season with salt, black pepper, and garlic powder, then mix until smooth and creamy.

👉 Pro Tip: Chill the sauce in the refrigerator for at least 30 minutes 🧊
This allows the flavors to blend together and taste even better!

🔥 2. Prepare the Smash Beef

Heat a skillet or griddle over medium-high heat and lightly grease it.

Place about 2–3 tablespoons of ground beef directly onto each tortilla.
Press it down gently to create a thin, even layer, then sprinkle with salt.

Place the tortilla meat-side down onto the hot skillet.
Cook for 4–5 minutes until the beef is fully cooked and develops a crispy crust.

Flip and cook the tortilla side until golden and slightly crispy.

👉 Pro Tip: Don’t move the meat too much while cooking—this helps create that perfect crispy smash burger crust 🔥

🧀 3. Assemble the Tacos

While the tacos are still warm:

• Add a slice of cheddar cheese (let it melt 😍)
• Top with fresh chopped lettuce
• Add caramelized onions for extra flavor

Finish with a generous drizzle of your homemade In-N-Out style sauce 🤤
