Quick Answer
Five Guys burger bowls with cheese, bacon, and lettuce wraps are the cleanest keto orders. Fries are cooked in peanut oil, which is an allergen consideration. Hot dog buns and ketchup contain sugars. The lettuce wrap customization is the key zero-carb move.
Five Guys Keto: How the Menu Scores on Ingredient Quality
A PQ Score is CleanKeto's ingredient quality measure, running from 0 to 100. It reflects what is actually in the food at the ingredient level, not just macros. A patty with no additives scores very differently than a condiment loaded with high fructose corn syrup, even if both fit a carb budget on paper. Here is how the core Five Guys menu items break down.
| Item | PQ Range | Key Concern | Sweetener | Verdict |
|---|---|---|---|---|
| Hamburger Patty (plain) | 70-85 | None significant | None | Best pick |
| Bacon | 55-70 | Sodium, curing agents | None | Good |
| American Cheese | 45-60 | Processed cheese blend | None | Acceptable |
| Lettuce (wrap base) | 85-95 | None | None | Zero-carb win |
| Regular Bun | 20-35 | Refined flour, added sugar | Added sugar | Skip |
| Ketchup | 15-25 | High fructose corn syrup | HFCS | Avoid |
| Cajun Fries | 25-40 | High carbs, peanut oil | None | Not keto |
| Regular Fries | 25-40 | High carbs, peanut oil | None | Not keto |
| Mayonnaise | 55-70 | Soybean oil | None | Use sparingly |
| Yellow Mustard | 65-80 | Minimal additives | None | Good |
| Hot Sauce | 60-75 | Check sodium | None | Fine |
| Grilled Mushrooms | 80-90 | None | None | Solid add-on |
| Jalapenos | 80-90 | None | None | Solid add-on |
The patty is where Five Guys earns its reputation. Their beef uses no soy extenders, no breadcrumbs, no binders of any kind. Ingredient analysis places their hamburger patties in the 70-85 PQ range, which is strong for fast food across the board. You are getting a clean protein source. That matters.
Bacon lands in the 55-70 range depending on the curing method and sodium levels. American cheese scores lower due to the processed cheese blend, but still falls into acceptable territory for a keto build. Grilled mushrooms and jalapenos are both clean ingredients with no real concerns, and they push the overall meal quality up without adding any meaningful carbs.
Now for the watch-outs. Ketchup is where a lot of keto eaters get quietly derailed. One pump is not a big deal calorie-wise, but the first ingredients in standard ketchup are tomato concentrate and high fructose corn syrup. That scores 15-25 on ingredient quality. Mustard clears 65-80 by comparison. Hot sauce sits in the 60-75 range depending on the brand used at your location. The sauce swap is one of the easiest ingredient quality improvements you can make without sacrificing anything.
The fries situation deserves its own note. Five Guys uses peanut oil in their fryers, and they are not shy about it. Shelled peanuts are available throughout the dining area, and peanut oil is a recognized part of the brand. For most people this is a non-issue, but peanut oil is derived from a top-eight allergen, and the cross-contact environment inside a Five Guys is notably high. Anyone with peanut sensitivity should speak with their healthcare provider before eating here. From a pure keto standpoint, the fries are not viable due to carbohydrate content regardless of the oil.
Building Your Five Guys Keto Order: A Step-by-Step Checklist
You are standing at the counter. The menu is on a chalkboard and the line is moving. Here is how to build a clean five guys low carb order without needing to consult a spreadsheet.
Step 1: Start with your protein choice. Go with the hamburger or cheeseburger, no bun. If you want a lighter option, the "Little Hamburger" is a single patty version. The standard burger comes with two patties by default, which works well for a satisfying keto meal. Hot dogs are an option in terms of being low-carb when ordered without the bun, but the patties score higher on ingredient quality than the hot dogs, so start there.
Step 2: Decide between a lettuce wrap or a burger bowl. Both are zero-bread options. The five guys lettuce wrap uses several layers of iceberg lettuce to hold the burger together, and staff are completely familiar with the request. A burger bowl arrives in a foil container with everything assembled inside, easier to eat with a fork if you load up on toppings. Neither requires a special menu item or upcharge.
Step 3: Choose your toppings strategically. Green lights for keto: bacon, American cheese, lettuce, tomato, grilled mushrooms, grilled onions, jalapenos, green peppers, pickles, A.1. sauce in small amounts, mustard, hot sauce, and mayo if you are not concerned about soybean oil.
Skip: ketchup, barbecue sauce, and any honey-based sauce. Those ingredients score poorly on quality analysis due to added sugars and HFCS. Relish also contains added sugar, so use it sparingly or skip entirely.
Step 4: Deal with the fries question before you order, not at the counter. There is no keto-appropriate fry option. This is not a gap Five Guys has filled, and it is unlikely to change. The better move is to build a more substantial burger. Double patty, extra bacon, mushrooms, cheese. Make the burger the whole meal. A double cheeseburger bowl with bacon and grilled mushrooms in a lettuce wrap is a genuinely filling, high-protein, quality-ingredient meal.
Step 5: Handle beverages. Diet sodas are available, but they contain aspartame or other artificial sweeteners depending on the brand. Water is the cleanest zero-carb choice. If you care about sweetener quality beyond just carbs, water or unsweetened sparkling water is the only no-concern option.
Step 6: If allergens are in play, ask before you order. Five Guys keeps an allergen card at the counter. Peanut oil is in the fryers. Tree nuts are not a concern in the same way, but the peanut environment is real. If you are ordering for someone with food allergies, review that card or check Five Guys' published allergen information before ordering.

Key Takeaways
- Five Guys hamburger patties score 70-85 on ingredient quality analysis, making them one of the cleaner fast food protein options available because the beef contains no fillers, binders, or soy extenders.
- Ordering a five guys lettuce wrap or burger bowl brings the bread carbs to zero, and both are accepted customizations that staff handle without issue.
- Ketchup contains high fructose corn syrup and scores 15-25 on ingredient analysis. Mustard scores 65-80. Swapping condiments is one of the highest-impact, lowest-effort moves you can make at this chain.
- Peanut oil is used in all fryers, making fries a skip for keto (carb content) and a potential concern for anyone with peanut sensitivity.
- Clean keto prioritizes ingredient quality alongside carb counts. Five Guys can fit that framework when you build a burger bowl thoughtfully, even if the standard menu looks carb-heavy at first glance.
