The Ultimate Guide to Copycat Restaurant Sauces
Make your favorite restaurant sauces at home. From Big Mac sauce to Raising Cane's, Chick-fil-A, Outback blooming onion, and 16 more — every copycat recipe in one place.
The sauce is almost always what you're actually craving. Not the burger itself. Not the chicken tenders. The sauce. These 19 copycat recipes cover every major restaurant sauce worth making at home — organized by use so you can find what you need fast.
A few things hold true across all of them: mayo quality matters more than any other single ingredient, homemade versions tend to taste fresher than the original, and most of these come together in under five minutes.
Fast Food Burger & Chicken Sauces
The heavy hitters. These are the sauces people drive through the window specifically to get.
Big Mac Special Sauce
The most famous burger sauce in the world. Sweet relish, mayo, mustard, and a handful of pantry spices. The commercial version uses a slightly different ratio than what you'd expect, which is why homemade versions usually taste better — you can balance it exactly to your preference. Great on burgers, obviously. Also good as a fry dip.

Copycat Chick-fil-A Sauce
Honey mustard crossed with barbecue sauce. That's the skeleton of this one. The key is using good quality mayonnaise — the cheap stuff dulls the whole thing. Get the ratio right and it tastes indistinguishable from the packet. Doubles as a sandwich spread or veggie dip.

Raising Cane's Sauce
One of the most searched copycat sauces on the internet, and for good reason — it's extremely good and Raising Cane's only serves it with one thing (chicken fingers). The base is mayo, ketchup, garlic powder, and Worcestershire. Simple. The secret is letting it rest overnight in the fridge so the flavors meld. Do not skip that step.
Culver's Signature Sauce
Buttermilk, Parmesan, and blue cheese make this one different from every other fast food sauce. It's creamy without being heavy, tangy without being sharp. If you're a Culver's fan, this tastes exactly right. If you've never had it, think of it as an elevated ranch.

Whataburger Creamy Pepper Sauce
Smooth, smoky, and mildly spicy. Whataburger's creamy pepper sauce is a regional favorite that doesn't get enough attention outside the South. If you've had it, you know. Good on burgers, grilled chicken sandwiches, or anywhere you'd use a chipotle mayo.

Cookout Sauce
Cookout is a regional drive-in chain with a devoted following. Their sauce is a creamy, smoky, slightly sweet condiment that works on everything from burgers to fries to grilled meats. If you're outside the Southeast and can't get to a Cookout, this recipe has you covered.
Chicken & Wing Sauces
Dipping sauces for chicken tenders, wings, and anything that comes out of the fryer.
KFC Finger Lickin' Good Sauce
KFC's take on a honey mustard dipping sauce. Tangier and a little thinner than typical honey mustard, designed specifically for dipping fried chicken. Comes together in minutes from pantry staples.

Buffalo Wild Wings Spicy Garlic Sauce
One of the best sauces on the BWW menu. The spicy garlic sauce is hotter than you'd expect from a chain wing sauce, with a real garlic presence that lingers. This recipe nails it. Toss wings, drizzle on pizza, or use it as a dip.

Zaxby's Chicken Fingers Dipping Sauce
Zax Sauce is a mayo-based dipping sauce with a gentle heat and a hint of tang. It's versatile — works for chicken fingers, sandwiches, or as a spread. The balance of sweet and spicy is well-calibrated in the original, and this recipe matches it closely.

Arby's Horsey Sauce
Arby's sells more horsey sauce packets than almost any other condiment. It's basically a creamy horseradish mayo — simple, sharp, and genuinely good on roast beef. Takes two minutes to make. The ratio of horseradish to mayo is the whole ballgame here.
BBQ & Grill Sauces
Alabama White BBQ Sauce
Most people only know red BBQ sauce. Alabama white sauce is tangy, mayo-based, peppery, and outstanding on smoked chicken. If you've never used it, it changes grilled and smoked poultry completely. Apply it like you would a red sauce — brush it on at the end of the cook or serve it on the side.

Copycat Sheetz Boom Boom Sauce
Boom Boom sauce is creamy, sweet, tangy, and mildly spicy with a strong garlic note. Sheetz's version is a cult favorite among convenience store sauce fans (yes, that's a real category). The homemade version is noticeably fresher. Good on fries, burgers, or chicken.

Starters & Dips
Outback Blooming Onion Sauce
The sauce that makes the blooming onion worth ordering. Creamy, zesty, with a horseradish-forward kick and a hint of heat. This one works far beyond blooming onions — it's a great dip for fries, onion rings, or any fried appetizer.

Bojangles' Gravy
Bojangles' is a Southern breakfast chain, and their sawmill-style gravy over biscuits is the whole point of the experience. Creamy, savory, well-spiced. This recipe captures the real flavor. Make it for biscuit gravy any morning — or pour it over fried chicken at dinner.
Chive-Onion Top the Tater Copycat
If you're from Minnesota, you already know exactly what this is. Top the Tater is a chive-onion sour cream dip that belongs on baked potatoes, chips, and raw vegetables. The copycat version nails the creamy, herby flavor. A regional obsession worth making everywhere.

Dressings
Portillo's Chopped Salad Dressing
Portillo's Chicago chain serves a chopped salad with a tangy, slightly sweet Italian dressing that's become a regional institution. The dressing itself is the reason people order the salad. This recipe makes a versatile vinaigrette that works on any Italian-style salad.

Runza Ranch Dressing
Runza is a Nebraska chain, and their ranch dressing has a devoted regional following. Thicker and more flavorful than bottled ranch, with a proper buttermilk tang. Good on salads, wraps, or as a dip.
Giordano's Lemon Vinaigrette
Giordano's is famous for deep dish pizza, but this lemon vinaigrette from their salad menu is underrated. Bright, balanced, and better than most bottled dressings. Works on any simple green salad.

Spreads
Copycat Texas Roadhouse Honey Cinnamon Butter
The butter they bring out with the rolls at Texas Roadhouse is why people go to Texas Roadhouse. Lightly whipped, honey-sweet, and warm with cinnamon. Takes five minutes to make and tastes identical. Serve it at room temperature on homemade rolls, cornbread, or toast.

What Makes Copycat Sauces Work
These recipes succeed when you follow a few consistent rules.
Use good mayonnaise. Most of these sauces are mayo-based. Duke's and Hellmann's both work. Store-brand mayo produces a noticeably duller result. This is the single biggest variable.
Let them rest. Any sauce with garlic, onion powder, or Worcestershire improves after sitting in the fridge for at least an hour. Overnight is better. The flavors round out and blend in a way they can't when freshly made. Raising Cane's sauce is the clearest example — it tastes completely different after 24 hours.
Taste against the original. If you've had the real thing recently, your memory is the best calibration tool you have. Adjust salt, acid, and heat at the end before serving.
Double the batch. Most of these keep for a week or more in the fridge. There's no reason to make a small amount when you're already mixing.
