🛒 Ingredients You’ll Need

🍔 The Famous Secret Spread:

• ½ cup Mayonnaise 🥣
• 3 tbsp Ketchup 🥫
• 1 tbsp Sweet pickle relish 🥒
• ½ tsp Yellow mustard 🌭
• ½ tsp White vinegar 🍾
• ⅛ tsp Granulated sugar 🧂

🧅 The Caramelized Onions:

• 2 large Yellow onions (finely diced) 🧅
• 1 tbsp Butter 🧈
• 1 tbsp Vegetable oil 🍾
• ¼ tsp Salt 🧂
• 2 tbsp Water (for deglazing) 💧

🍟 The Base & Toppings:

• 1 lb Frozen french fries (shoestring or extra-crispy cut work best) 🍟
• 4 slices American cheese (real melt-friendly cheese!) 🧀

👨‍🍳 Step-by-Step Instructions

Step 1: Whip Up the Spread 🥣

1. In a small bowl, combine the mayonnaise, ketchup, sweet relish, yellow mustard, vinegar, and sugar.
2. Whisk until completely smooth.
3. Cover and place in the fridge so the flavors can meld together while you cook.

Step 2: Caramelize the Onions 🧅

1. Heat the butter and oil in a large skillet over medium-low heat.
2. Add the diced onions and salt.
3. Cook low and slow for 25 to 30 minutes, stirring every few minutes. As they brown, splash in a tablespoon of water whenever the pan looks dry to scraped up those delicious browned bits!
4. Once the onions are deep golden brown and jammy, remove them from heat.

Step 3: Bake or Fry the French Fries 🍟

1. Cook your favorite frozen french fries according to the package instructions.
2. Pro Tip: Air-fry or deep-fry them until they are extra crispy so they hold up under all the juicy toppings!

Step 4: Assemble the Animal Style Magic ✨

1. Transfer your piping-hot fries onto an oven-safe tray or baking dish.
2. Layer the 4 slices of American cheese directly on top of the warm fries.
3. Broil in the oven for 1–2 minutes (or microwave for 20 seconds) just until the cheese is beautifully melted and gooey. 🧀
4. Scoop the warm caramelized onions right over the melted cheese.
5. Finish with a generous drizzle of your homemade secret spread! 💥

💡 Chef’s Secret Tips for Success

• Double the Spread: You are definitely going to want extra spread for dipping your burgers or extra fries into!
• Don’t Rush the Onions: Low and slow is the key. High heat will burn the onions instead of caramelizing them into sweet, savory perfection.
• Cheese Matters: Stick to classic American cheese slices for that authentic, gooey In-N-Out texture.

🍽️ How to Serve

Serve immediately while hot and crisp! Pair these with home-style burgers, icy milkshakes, or cold lemonades for the ultimate diner-style dinner night. 🍔🥤
