Five Guys Burger- Is It Kosher?
The Short Answer
No. Five Guys is not kosher. Period. If you're keeping kosher and hoping for an exception, there isn't one.
Five Guys has zero kosher certification. They don't market themselves as kosher, they don't label anything as kosher, and they have zero plans to change that. This isn't some oversight or gray area—it's a deliberate business decision.
Why Five Guys Isn't Kosher
Multiple reasons. Let's break it down:
No Certification
Kosher isn't just about ingredients. It requires certification from a recognized rabbinical authority. Five Guys has never sought this. They don't have mashgichim (kosher supervisors) on staff. No rabbi oversees their food preparation.
Peanut Oil
Five Guys fries everything in 100% peanut oil. This alone isn't a dealbreaker for many kosher-keeping Jews—peanut oil is generally considered kosher. But it's a red flag for those with peanut allergies, and it complicates the "is it kosher?" question when combined with everything else.
Cross-Contamination Is Rampant
Look at how Five Guys operates. Burgers and hot dogs cook on the same grill. Bacon bits scatter everywhere. Cheese sits on shared surfaces. Fries get dumped in the same containers.
There's zero separation between meat and dairy. Zero. A cheeseburger at Five Guys isn't just non-kosher—it's a treif explosion.
No Supervision Means No Guarantees
Even if the ingredients were somehow individually kosher, without supervision you have no way of knowing:
- When equipment was last cleaned
- What oils or fats were used previously
- Who handled the food and how
- If any ingredients were swapped or substituted
Kosher certification exists because you need someone watching. Five Guys has no one watching.
What Would Actually Make Five Guys Kosher?
For Five Guys to become kosher, they'd need to:
- Hire certified mashgichim for every location
- Separate all meat and dairy completely
- Source only certified kosher ingredients
- Change their entire prep and cooking process
- Get inspected regularly
Will this happen? Not a chance. Five Guys built their brand on consistency and simplicity. Adding kosher certification would require a complete operational overhaul. They're not going to do that for a niche market segment.
Kosher Fast Food Alternatives
If you need a burger fix and must keep kosher, here are actual options:

Your best bet is to use apps like Kosher Alert or OK Kosher Certification's app to find certified restaurants near you. Don't guess—verify.
If You Still Want Five Guys
Look, I get it. Five Guys tastes good. If you're eating there and don't keep strict kosher, fine. But if you keep even somewhat strict kosher:
- Don't eat there—it's not worth the risk
- Don't rationalize it—"just fries" still cross-contaminates
- Don't ask for exceptions—they won't accommodate you
Some people say "I only eat the fries." The fries are fried in peanut oil that's been used for everything else. That's not kosher. Not even close.
The Bottom Line
Five Guys is not kosher. Not certified, not close, not worth trying to make it work. If kosher compliance matters to you, Five Guys is off the table—completely.
Find a certified restaurant. Use the resources available. Don't compromise your standards for a burger chain that doesn't care about yours.
