Ingredients for burger 21 sauce
Seven simple ingredients transform into that iconic creamy, smoky sauce you crave.
| Ingredient | Amount | Notes |
|---|---|---|
| Ketchup 🍅 | ½ cup | High-quality, smooth variety |
| Mayonnaise 🥫 | ½ cup | Full-fat for creaminess |
| Sweet Pickle Relish 🥒 | ¼ cup | Fine-chopped, no seeds |
| Celery Salt 🧂 | 1 tsp | Diamond Crystal preferred |
| Chipotle Powder 🌶️ | ½ tsp | Smoked, not powdered chips |
| White Vinegar 💧 | 1 tbsp | For tangy brightness |
| Garlic Powder 🧄 | ¼ tsp | Freshly ground preferred |
The ketchup and mayo are non-negotiable here—Heinz and Hellmann's are my go-tos, but any good brand works. Relish is where the magic happens: Sweet pickle relish gives that bright, tangy bite. Skip the dill or bread-and-butter—this needs to be the sweet kind. For the celery salt, Diamond Crystal has that perfect balance of salt and celery flavor. Chipotle powder? Penzeys or Simply Organic deliver the smoky depth without overpowering. Pro tip: Toast the chipotle powder in a dry pan for 30 seconds before adding—trust me, it makes all the difference.
No relish? Dill pickle juice plus a pinch of sugar gets you close. Short on mayo? Greek yogurt at half the amount keeps it creamy. The vinegar is non-negotiable for tang—apple cider vinegar works too if you're avoiding white. Want more heat? Add a pinch of cayenne. For a smoother texture, blend everything in a food processor for 10 seconds. But if you're making this for onion rings, leave it slightly chunky—that's part of the fun!
This sauce keeps beautifully in the fridge for up to 1 week in an airtight container. For extra freshness, press plastic wrap directly onto the surface before sealing. Freezes for 3 months—perfect for batch cooking. I always make double because it disappears faster than you'd think. The first batch is for burgers, the second? Fries, hot dogs, or sandwiches. You'll be hooked.

Step-by-step instructions for burger 21 sauce
This sauce delivers that signature creamy, smoky depth with a subtle tangy kick—simple ingredients, big flavor.
Whisk Together the Base Ingredients
In a medium bowl, combine the 0.5 cup ketchup and 0.5 cup mayonnaise. Use a whisk to blend them smoothly until fully incorporated. This base creates the creamy foundation, so take your time to ensure there are no streaks of either ingredient. The ketchup adds sweetness while the mayo provides that rich, velvety texture that makes this sauce irresistible.
Next, add the 0.25 cup sweet pickle relish and stir it in with the whisk. The relish brings a bright, tangy contrast that balances the richness of the mayo and ketchup. You'll notice the mixture lighten in color slightly as the relish blends in, giving it that signature golden hue. If you're using a relish with seeds, strain it first to avoid any texture surprises.
Add the Spices and Vinegar
Now it's time to build the depth of flavor. Sprinkle in the 1 tsp celery salt, 0.5 tsp chipotle powder, 0.25 tsp garlic powder, and 1 tbsp white vinegar. The celery salt adds a subtle, earthy complexity that complements the smokiness of the chipotle. Stir everything together until the spices are evenly distributed and the vinegar is fully incorporated.
Here's where the magic happens: the vinegar cuts through the richness of the mayo and ketchup, adding a bright, tangy lift that keeps the sauce from being too heavy. The chipotle powder brings that signature smoky heat, while the garlic powder adds a warm, aromatic backbone. Taste the mixture now—you should notice a balance of sweet, tangy, and smoky flavors. If it needs more tang, add a tiny splash more vinegar.
Let It Rest for Maximum Flavor
Once everything is thoroughly mixed, transfer the sauce to an airtight container and let it sit at room temperature for at least 15 minutes. This resting period allows the flavors to meld together, deepening the smoky notes and letting the vinegar's tang develop fully. It also gives the celery salt time to dissolve completely, ensuring a smooth, cohesive texture.
After resting, give the sauce one final stir before serving. The flavors will have come together beautifully, creating that signature creamy, slightly spicy, and tangy profile that makes Burger 21 sauce so addictive. If you're using this sauce for burgers, let it sit on the patty for a minute or two before eating—this lets the flavors soak in and intensify.
Adjust and Serve
If the sauce is too thick, thin it with a teaspoon of water or a splash of vinegar until it reaches your desired consistency. It should coat the back of a spoon smoothly but still cling to the burger without dripping. If it's too thin, let it sit for another 5-10 minutes to thicken slightly.
Serve the sauce immediately on burgers, hot dogs, or fries for the best experience. The warmth of the food will enhance the smoky, creamy flavors, making every bite irresistible. Store any leftovers in the refrigerator for up to 5 days, but be warned—this sauce disappears fast!
Pro Tips For Making Burger 21 Sauce
- STIR IN STAGES: Mix the ketchup and mayo first, then fold in the relish last—this keeps the texture smooth instead of breaking the mayo. I learned this the hard way when I dumped everything in at once and ended up with a lumpy mess.
- USE FRESH RELISH: That jarred relish sitting in your pantry for a year? Toss it. Fresh or high-quality sweet pickle relish makes a real difference in flavor and texture—no graininess, just bright tang. (Yes, even if you’re impatient like me.)
- TAMP THE SPICES: Press the chipotle powder and celery salt into the sauce with the back of a spoon after mixing. This distributes the heat and celery flavor evenly instead of letting it pool at the bottom like a lazy seasoning dump.
- CHILL BEFORE SERVING: Let the sauce sit in the fridge for at least 30 minutes after making it. The flavors meld better, and the mayo firms up just enough to hold its shape on the burger—no more sad, runny drips. (Your future self will thank you.)

Protein-Packed Creaminess
The mayo base provides healthy fats that help your body absorb fat-soluble vitamins like A and E from the ketchup and relish.

Antioxidant Boost
Both ketchup and relish contribute antioxidant benefits from their tomato and pickle bases. The white vinegar adds acetic acid, which has been shown to help regulate blood sugar levels.
Chipotle powder contains capsaicin, a compound that boosts metabolism and may help reduce inflammation. This makes the sauce not just delicious, but also packed with functional benefits.
Low-Sodium Option
For those watching sodium intake, you can reduce the celery salt to ½ tsp without sacrificing much flavor. The vinegar and chipotle still deliver that signature tang and heat.
I've tested this version and found it still maintains that perfect balance—just with 20% less sodium per serving. The relish provides enough natural saltiness to compensate.
Digestive Aid
The combination of garlic powder and pickle relish creates a digestive-friendly sauce. Garlic contains compounds that support gut health, while the acidity from vinegar helps stimulate digestive juices.
This makes it an excellent choice for pairing with heavy foods like burgers or fries, helping your body process them more efficiently. 🌱
Versatile Nutrition
While this sauce is delicious on burgers, its nutritional profile makes it great for other meals too. The healthy fats from mayo help keep you full longer, while the fiber from relish supports digestive health.
