Try these Double-Double Animal Style burgers at home — an easy, authentic-feeling copycat of a classic fast-food favorite. With thin mustard-fried patties, melted American cheese, special sauce, pickles, tomato, lettuce and caramelized onions on a toasted bun, these burgers deliver big, familiar flavor with straightforward techniques you can recreate in your kitchen.
If you aren’t familiar with the original, it’s a popular West Coast burger known for its simple yet highly satisfying composition. This version stays true to that spirit while offering clear, step-by-step guidance so you can make the Double-Double Animal Style at home.
Recipe Notes
- Toast the buns early and keep them warm: Toast, pair, and set the buns aside inside their packaging or wrapped so they stay warm while you finish the patties.
- Keep patties on the wax paper until you’re ready to fry: These patties are formed very thin. Leaving them on the wax paper prevents tearing or falling apart when you transfer them to the hot pan.
- Mustard on the patties is essential: Spreading a little mustard on the patties just before frying creates that flavorful crust without making the burgers taste overtly of mustard.

How to make the Double-Double Animal Style Burger
Caramelized Onions
- Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add finely diced yellow onions and ½ teaspoon salt, stir to combine.
- Reduce heat to medium-low and cook, stirring occasionally, for 15–20 minutes or until the onions are lightly browned.
- Return heat to medium-high and add 1 tablespoon water. Stir and cook 2–3 minutes until the water evaporates or the onions begin to cling to the pan. Repeat this step two more times to deepen the caramelization.
- Transfer onions to a container and refrigerate until ready to use.
Special Sauce
- Whisk together 1/3 cup mayonnaise, 3 tablespoons ketchup, 1½ tablespoons sweet pickle relish, 1 teaspoon sugar and 1 teaspoon white vinegar until smooth. Cover and chill — the flavor improves as it rests.
Buns
- Heat a skillet over medium-high heat and add about 1 teaspoon butter per bun. Toast the inside of the buns for about 1 minute until edges are golden brown. Set aside and keep warm.
Mustard-Fried Beef Patties
- Use 1 pound ground beef (about 20% fat recommended). Divide into eight equal pieces and roll each into a ball.
- On a large piece of wax paper, flatten each ball into a very thin patty about 4 inches in diameter or slightly larger than the bun. Season with salt and pepper.
- Cut a square of wax paper around each patty and stack them to keep them separated and easy to handle.
- Heat a large skillet over medium-high heat with a light coating of oil. The pan should be very hot before adding patties.
- Place two patties in the pan (seasoned side down). Quickly season the top with salt and pepper, then spread about 1 tablespoon yellow mustard over the exposed surface of each patty.
- Cook until browned, about 2–3 minutes. Flip and cook 1 more minute, then add a slice of American cheese to each patty. Spoon a heaping tablespoon of caramelized onions onto one patty, then stack the second cheese-covered patty on top. Remove the stack and repeat with remaining patties.
Assembly
Assemble each burger following the layer order described above so each bite contains sauce, tangy pickles, fresh tomato and lettuce, and the cheesy, onion-studded double patty stack. Serve immediately while warm for the best texture and flavor.
Make-Ahead Tips
To speed up cooking and assembly, do as much prep as possible in advance:
- Caramelize the onions ahead of time — they take the longest and store well in the fridge.
- Make the special sauce earlier. It tastes better after resting and keeps refrigerated for several days.
- Form the patties on wax paper and stack them separated by paper squares. Store the stack in a container in the refrigerator until ready to cook.
- Toast buns just before serving for optimal texture, but you can pre-butter and keep them warm if needed.
Enjoy these Double-Double Animal Style burgers hot from the pan — they capture the bold, nostalgic flavors of the original with components you can make at home. If you prepare the onions and sauce in advance, cooking and serving become quick and satisfying.
