Arby’s Red Ranch Sauce Copycat Recipe
Arby’s red ranch sauce is that tangy, slightly smoky condiment that makes their roast beef sandwiches genuinely hard to put down. If you want it at home, this recipe gets you there in about 5 minutes with pantry staples you probably already have.
It keeps in the fridge for a week, so you can make it once and use it all week long.
Why I Love This Recipe
The combination of ketchup and ranch dressing sounds almost too simple, but the smoked paprika is what pulls it together. It gives the sauce a subtle warmth without real heat.
This is the version I keep coming back to because the ratio is easy to remember and the result is actually close to the original, not just a generic pink sauce.
Recipe Ingredients
- 2 tbsp ketchup – Use a standard ketchup; nothing fancy needed here
- 3 tbsp mayonnaise – Full-fat gives the creamiest texture
- 2 tbsp buttermilk – Thins the sauce to a drizzleable consistency and adds a slight tang
- 1 tsp white vinegar – Brightens the whole thing; apple cider vinegar also works
- 1/2 tsp smoked paprika – The key flavor note that separates this from plain pink sauce
- 1/4 tsp garlic powder – Savory backbone
- 1/4 tsp onion powder – Rounds out the garlic without being sharp
- 1/4 tsp dried dill – Ties it to the ranch side of the sauce
- 1/4 tsp salt – Adjust to taste at the end
- 1/8 tsp black pepper – Freshly ground if you have it
Variations / Substitutions
- No buttermilk – Use 2 tbsp regular milk with a small squeeze of lemon juice and let it sit for 2 minutes; the texture will be nearly identical.
- Spicier version – Add 1/4 tsp cayenne or a few drops of hot sauce to get a noticeable kick without changing the flavor profile.
- Lighter swap – Replace the mayonnaise with Greek yogurt; the sauce will be a little thinner and tangier but still works well as a dip.
- Extra smoky – Use 3/4 tsp smoked paprika instead of 1/2 tsp, which deepens the color and adds a more pronounced smokiness.
- Dairy-free – Swap the buttermilk for unsweetened oat milk with a squeeze of lemon and use a vegan mayonnaise; the consistency stays close.

How To Make Red Ranch Sauce
Step 1: Whisk the Base
Add the 3 tbsp mayonnaise and 2 tbsp ketchup to a small bowl and whisk them together until the color is uniform, about 30 seconds. Pour in the 2 tbsp buttermilk and the 1 tsp white vinegar, then whisk again until smooth.
You should see a pale coral-orange color at this point. If the mixture looks streaky, keep whisking for another 15 seconds.
Step 2: Season the Sauce
Add the 1/2 tsp smoked paprika, 1/4 tsp garlic powder, 1/4 tsp onion powder, 1/4 tsp dried dill, 1/4 tsp salt, and 1/8 tsp black pepper directly into the bowl. Whisk everything together for about 45 seconds until the spices are fully incorporated and no dry pockets remain.
The color will shift to a deeper, richer red-orange once the paprika is mixed in. Taste it now and adjust salt if you feel it needs it.
Step 3: Chill and Serve
Transfer the sauce to a small jar or airtight container and refrigerate for at least 15 minutes. The resting time lets the dried herbs and spices bloom and the flavors come together into something more cohesive than it tastes straight off the whisk.
Pour it into a small serving dish, give it a final stir, and drizzle a thin line of ketchup across the top before bringing it to the table.
Recipe Tips
- Whisk, don’t stir – A fork or spoon will leave lumps of spice sitting in pockets; a small whisk emulsifies everything in less than a minute.
- Taste before chilling – The salt level changes slightly once the sauce is cold, so always check seasoning while it is still at room temperature and adjust before refrigerating.
- Double the batch – The sauce works as a burger spread, a dipping sauce for fries, and a drizzle on grain bowls, so making 2x the recipe on Sunday saves you time all week.
- Smoked vs. sweet paprika – Sweet paprika will produce a milder, flatter sauce; smoked is worth buying if you do not already have it.
Sauce thickness varies by how you plan to use it — here is a quick guide:
| Use | Buttermilk amount | Consistency |
|---|---|---|
| Sandwich spread | 1 tbsp | Thick, spreadable |
| Dipping sauce | 2 tbsp | Medium, scoopable |
| Drizzle or dressing | 3 tbsp | Thin, pourable |
How To Store
- Refrigerate – Store in an airtight jar or container for up to 7 days. Give it a quick stir before each use, as the buttermilk can settle slightly.
- Serve Cold – This sauce is served cold and does not need reheating; it actually tastes better straight from the fridge after the first day.
What To Serve With Red Ranch Sauce
Roast beef sandwiches are the obvious home, and the sauce’s mild acidity cuts through the richness of the beef well. It also works as a dipping sauce for thick-cut potato wedges because the smokiness in the paprika pairs with the starchy crust. Chicken tenders are another strong match, where the tangy ranch side of the sauce balances the crispy coating.
Frequently Asked Questions
Can I make this sauce ahead of time?
Yes, and it actually improves after a few hours in the fridge. Make it up to 3 days ahead and store it covered.
Why does my sauce taste flat?
The most likely reason is that the smoked paprika you used is old. Paprika loses its punch faster than most spices; if yours smells faintly of dust, replace it.
Can I use sour cream instead of mayonnaise?
Yes, though the sauce will be noticeably tangier and slightly thinner. It works well as a dip but may be too sharp as a sandwich spread.
How close is this to the actual Arby’s sauce?
It is a solid home version. Arby’s proprietary blend likely uses stabilizers and concentrated flavors, so the homemade version tastes a little fresher and less uniform, which most people actually prefer.
