Copycat BK Stacker Sauce Recipe

I was curious about how to recreate this BK Stacker Sauce at home. After some experimenting and tweaking, I found a copycat recipe that matches the iconic flavor and might just be your new favorite go-to sauce for homemade burgers, fries, or even sandwiches.

How to make BK Stacker Sauce

BK Stacker Sauce is a signature condiment created by Burger King for its Stacker line of burgers. This sauce is known for its creamy, tangy, and slightly sweet flavor profile, which complements the savory elements of the burgers.

Ingredients

• ½ cup mayonnaise – The creamy base of the sauce.
• 2 tablespoons ketchup – Adds a touch of sweetness and tanginess.
• 1 tablespoon yellow mustard – For sharp, tangy notes.
• 2 teaspoons sweet pickle relish – Brings mild sweetness and crunch.
• ½ teaspoon Worcestershire sauce – Adds depth and umami flavor.
• ½ teaspoon onion powder – For a subtle savory kick.
• ½ teaspoon garlic powder – Enhances the savory profile.
• 1 teaspoon white vinegar – Balances the flavors with mild acidity.
• Pinch of smoked paprika (optional) – For a slight smoky touch.

Instructions

1. Prepare the Ingredients: Start by measuring all your ingredients to ensure they are ready for mixing. Use fresh, high-quality ingredients for the best flavor!

2. Mix the Sauce: In a mixing bowl, combine the mayonnaise, ketchup, mustard, and sweet pickle relish. Stir well until the ingredients are evenly blended.

3. Add Seasonings for Flavor: Stir in the Worcestershire sauce, onion powder, garlic powder, and white vinegar. If you’re using smoked paprika, add a small pinch for extra depth of flavor.

4. Adjust Consistency: If the sauce feels too thick, you can add a teaspoon of water or vinegar to thin it out slightly. Taste as you go—it’s all about finding that perfect balance!

5. Chill Before Serving: Transfer the sauce into an airtight container and let it chill in the refrigerator for at least 30 minutes. Chilling allows the flavors to meld, creating a richer and more authentic taste.

Tips for Perfect BK Stacker Sauce

Making this sauce is easy, but these tips will help ensure you get it just right:

• Use Full-Fat Mayonnaise: Choose full-fat mayonnaise for a richer and creamier sauce that mimics the texture of Burger King’s original.
• Balance Sweet and Tangy: If you prefer a slightly sweeter sauce, add an extra teaspoon of ketchup or pickle relish. For a tangier profile, use a bit more vinegar or mustard.
• Make Ahead: The sauce tastes even better after chilling for a few hours or overnight. This allows the flavors to develop fully—and you’ll always be ready for burger night!
• Store Properly: Leftovers can be kept in an airtight container in the refrigerator for up to 5 days. Freshness is key to maintaining the rich flavor.
• Use it in Creative Ways: While perfect for burgers, try drizzling the sauce over fries, dipping chicken strips, or spreading it on sandwiches to replicate fast-food deliciousness.

Ingredients Substitutes

Even if you don’t have all the exact ingredients on hand, you can still make an authentic-tasting BK Stacker Sauce.

Substitutes for Mayonnaise

• Greek Yogurt: For a lighter version of the sauce, you can use plain Greek yogurt. It’s still creamy but offers fewer calories and more protein.

Ratio: Use a 1:1 ratio (½ cup Greek yogurt for ½ cup mayonnaise).

• Sour Cream: Another option for a creamy base. Sour cream will give the sauce a slightly tangier taste.

Ratio: Use a 1:1 ratio (½ cup sour cream for ½ cup mayonnaise).

• Vegan Mayo: If you want to make a vegan version, you can use any store-bought vegan mayonnaise.

Ratio: Use just as you would regular mayonnaise.

Substitutes for Ketchup

• Tomato Paste and Honey: Tomato paste alone is too thick and concentrated, but you can mix it with honey to mimic the sweetness of ketchup.

Ratio: To substitute for 2 tablespoons of ketchup, use 1 tablespoon of tomato paste mixed with 1 teaspoon of honey.

• Barbecue Sauce: Adds a smokier flavor, which can enhance the overall taste.

Ratio: Use a 1:1 ratio (2 tablespoons of BBQ sauce for 2 tablespoons of ketchup).

Substitutes for Yellow Mustard

Ratio: Use a 1:1 ratio (1 tablespoon Dijon mustard for 1 tablespoon yellow mustard).

• Spicy Brown Mustard: Adds a kick and texture.

Ratio: Use a 1:1 ratio (1 tablespoon spicy brown mustard for 1 tablespoon yellow mustard).

Substitutes for Sweet Pickle Relish

• Chopped Sweet Pickles: Finely chop sweet pickles to achieve a similar texture and sweetness.

Ratio: Use a 1:1 ratio (2 teaspoons chopped sweet pickles for 2 teaspoons sweet pickle relish).

• Dill Pickle Relish with Honey: Mix dill pickle relish with a bit of honey for a slightly different flavor.

Ratio: To substitute for 2 teaspoons of sweet pickle relish, mix 1 ½ teaspoons of dill pickle relish with ½ teaspoon of honey.

Substitutes for Worcestershire Sauce

• Soy Sauce: Adds umami, though it’s a bit saltier.

Ratio: Use half the amount (¼ teaspoon soy sauce for ½ teaspoon Worcestershire sauce).

• Fish Sauce: Another umami-packed substitute, but use sparingly.

Ratio: Use less than half the amount (⅛ teaspoon fish sauce for ½ teaspoon Worcestershire sauce).

• Balsamic Vinegar: Provides depth and sweetness.

Ratio: Use in equal amounts (½ teaspoon balsamic vinegar for ½ teaspoon Worcestershire sauce).

Substitutes for Onion Powder

• Grated Onion: Freshly grate a small amount of onion for a burst of fresh flavor.

Ratio: 1 tablespoon grated onion for ½ teaspoon onion powder.

• Onion Salt: Note that it will add more saltiness, so adjust other seasonings accordingly.

Ratio: Use half the amount (¼ teaspoon onion salt for ½ teaspoon onion powder).

Substitutes for Garlic Powder

• Fresh Garlic: Mince garlic finely or use a garlic press.

Ratio: Use 1 small clove of fresh garlic for ½ teaspoon garlic powder.
