$3.59 to $3.89 buys the listed version; two medium cartons come to $7.18 instead.
Burger King frings means half fries and half onion rings, and the chain already sells it. A Have-sies is one carton split between the two, recorded between $3.59 and $3.89, which is exactly what a single medium side costs. Building the same thing from two cartons is $7.18 for two mediums, at 730 calories. Twice the price buys twice the food, and only the built version carries a calorie figure.

How it works
Ask for a Have-sies by name
This is one of the rare cases where the counter name exists. Readings put the box at $3.59 and $3.89, the same as a single medium side.
Buy two cartons only if you want two cartons
Two mediums come to $7.18 for 730 calories. That is double the food and roughly double the money, so it answers a different question from the one the name implies.
Drop to smalls if the total matters
A small of each is $5.58 and 580 calories. No current reading puts either small carton below $2.79, so that is the floor on the built route.
Check whether onion rings are stocked at all
Some restaurants do not carry them. No amount of asking produces a mixed box in a kitchen with only one of the two sides.
Do not expect a calorie figure for the box
The company has published none for a Have-sies. A count of 380 turned up in checking and was left out, because it sits above both of the sides it mixes and cannot be right.
If something goes wrong
The name got nowhere at the counter
- Cause
- Frings is a customer word and Have-sies is the one on the menu
- Fix
- Ask for a Have-sies. Where that draws a blank too, order a small fry and a small onion rings and tip one into the other.
Two cartons cost twice as much as expected
- Cause
- Buying two sides gets two sides, not one mixed box
- Fix
- That is the arithmetic behaving. At $3.59 each, two mediums are $7.18 against $3.59 to $3.89 for the listed box.
This restaurant does not stock onion rings
- Cause
- Onion rings are not carried across the whole estate
- Fix
- Nothing substitutes for them here. Cheesy Tots at $1.49 or Chicken Fries are different orders rather than a workaround.
No calorie count is shown for the box
- Cause
- The last nutrition figures Burger King issued date from November 2022 and have no row for it
- Fix
- Use the two sides instead. A medium fry is 370 and a medium carton of rings 360, so half of each should land between those.
The value cartons looked cheapest but had no price
- Cause
- The only readings for both trace to a list dated 2023 and were excluded
- Fix
- Ask at the counter. The calorie side is answerable, at 230 for value fries and 200 for value rings, giving 430 for the pair.
The price differed from the figures here
- Cause
- Burger King publishes no US prices and its restaurants are almost all franchised
- Fix
- Treat these as what published listings showed in August 2026. Restaurant Brands International sets no board prices from Miami, Florida or anywhere else.
What’s fixed, and what actually varies
Most secret-menu entries describe something a chain refuses to sell. This one describes something it sells and hardly anybody notices.
Fixed
- A Have-sies is one carton holding half French Fries and half Onion Rings
- Two readings put it at $3.59 and $3.89, matching a single medium side
- Two medium cartons bought separately came to $7.18 for 730 calories
- Burger King publishes no calorie figure for the mixed box
- The mixture itself adds nothing to the price where those readings hold
Varies
- Whether a restaurant lists a Have-sies at all
- Its price, which came back at two figures and has no defensible middle
- Whether onion rings are stocked, which is not universal
- Value-carton prices, which could not be found current for either side
- How a franchisee prices sides against the figures above
Search the sides section of the Burger King app with your restaurant selected. A Have-sies listed there settles the whole question at a stroke, and its price sits beside the medium fry so the comparison takes one glance. If it is absent, the two-carton route is the fallback and its cost is the sum of two side prices on the same screen.
A secret item that is sitting on the sides menu
Half fries and half onion rings in one box is one of the oldest requests in fast food, and it appears on secret-menu lists for several chains. At Burger King it is not off-menu. A Have-sies is exactly that box, and two readings in August 2026 put it at $3.59 and at $3.89.
What makes those figures interesting is what they match. A medium carton of French Fries was recorded at $3.59, and a medium carton of Onion Rings at the same $3.59, with both bands topping out at $3.89. So the mixed box costs what either side costs on its own. The mixture is free.
Building it yourself is the expensive route. Two mediums are $7.18 and 730 calories, using company counts of 370 and 360. Two smalls are $5.58 and 580. Both give twice the food, which is fine if that is what you wanted, and neither is a cheaper way to get a mixed box.
One route cannot be priced at all. Value cartons of each are the smallest, and the single reading behind each traces to a list dated 2023, so no current figure exists for either. Calories still work there, at 230 and 200, so the pair is 430 with no total price. That asymmetry runs through this whole section: Burger King publishes nutrition and not prices.
The listed box has the reverse problem. No calorie figure has ever been published for a Have-sies, and a 380 count that surfaced in checking was left out, since a box of half a 370 fry and half a 360 ring cannot land above both. Everything else in the sides section behaves normally enough, with Cheesy Tots at $1.49, Chicken Fries at $4.49 for nine pieces and Mozzarella Fries at $4.98, none of which mixes with anything. Order a Whopper alongside and the company will tell you 670 calories for the sandwich and nothing at all for the box beside it.
Questions people ask
Does Burger King sell frings?
Yes, under the name Have-sies. It is one carton holding half fries and half onion rings, recorded at $3.59 and $3.89 in August 2026.
How much does it cost to build instead?
$7.18 for two medium cartons, or $5.58 for two smalls. Both give twice as much food as the listed box and cost roughly twice as much.
Does mixing the two cost extra?
Not where these readings hold. A Have-sies matches the price of a single medium fry or a single medium carton of rings to the cent.
How many calories are in a Have-sies?
Burger King has published none. A medium fry is 370 and a medium carton of rings 360, so half of each should sit between those figures.
What is the cheapest version?
Value cartons of each, in principle. Neither has a current published price, so that route has calories of 430 and no total anyone can quote.
What if the restaurant has no onion rings?
Then neither route works. Onion rings are not stocked everywhere, and no other side substitutes for them in this box.
Are these figures from the company?
The calorie counts are, dated November 2022. Prices came from published US listings on 19 August 2026, because Burger King publishes no US prices of its own.
