Individual Oyster Cracker Packets: Size, Calories & Ingredients
If you have ever tipped half a box of oyster crackers into a bowl and found the rest gone soft a week later, individually wrapped packets solve exactly that problem. This guide covers what is actually inside a single-serve oyster cracker packet — size, calories, ingredients, allergens and storage — using the label data from the Westminster Bakers oyster crackers we stock.
Do oyster crackers contain oysters?
No. It is the most common question about them, and the ingredient list settles it. Westminster Bakers oyster crackers contain:
Unbleached wheat flour, water, canola oil, salt, cane sugar, baking soda, yeast.
There is no oyster, no shellfish and no seafood of any kind in them. The name comes from how they are eaten, not what they are made of — they were the traditional accompaniment to oyster stew and clam chowder in New England, and the name stuck.
How big is one individual oyster cracker packet?
Each packet holds 0.5 oz of crackers, and a box contains 40 packets.
| Measure | Amount |
|---|---|
| Packet size | 0.5 oz (about 14 g) |
| Packets per box | 40 |
| Total cracker weight | 20 oz (40 × 0.5 oz) |
A 0.5 oz packet is sized as a single serving alongside one bowl of soup. Forty packets is why a single box tends to last most households a whole soup season rather than a couple of weeks.
Oyster cracker nutrition
These are the figures printed on the Westminster Bakers panel:
| Nutrient | Amount | % Daily Value |
|---|---|---|
| Calories | 45 | — |
| Total fat | 1 g | 1% |
| Trans fat | 0 g | — |
| Sodium | 80 mg | 3% |
| Total carbohydrates | 7 g | 3% |
| Protein | 1 g | — |
One honest caveat on the serving size. The panel above is stated per serving, and the pack does not print how many crackers or what weight one serving is. We are not going to guess at it. If you need the calories for a whole packet specifically, weigh it against the panel rather than assuming one packet equals one serving — and treat any site that gives you a confident per-packet number without stating its source with some suspicion.
What the numbers do tell you plainly: oyster crackers are a low-fat, low-sugar, low-sodium cracker. At 80 mg of sodium they are considerably lighter on salt than most crackers sold as soup accompaniments.
Allergens: these contain wheat
Oyster crackers are not gluten-free. The first ingredient is unbleached wheat flour, and the pack carries a "contains wheat" declaration.
This matters more than usual for anyone arriving here from a soup or broth search. Plenty of bouillon and stock products are labelled gluten-free — the Herb-Ox vegetable cubes we stock are one of them — so it is easy to assume the crackers alongside them are too. They are not. If you are cooking for someone with coeliac disease or a wheat allergy, oyster crackers are not the cracker for that bowl.
On the other hand, the ingredient list contains no dairy, no egg and no animal-derived ingredients, and no shellfish despite the name.
What else is and isn't in them
- Non-GMO
- No preservatives
- No artificial additives
- Seven ingredients in total, all of them ordinary pantry items
The short ingredient list is the practical reason the single-serve format works: there is no preservative doing the job of keeping them crisp, so the wrapper has to.
Why individual packets instead of a box?
The trade-off is straightforward.
What you gain
- They stay crisp. Every packet is sealed until the moment it is opened. With no preservatives in the recipe, an opened box is on a clock; a sealed packet is not.
- Portion control without measuring. One packet, one bowl. Useful if you are tracking intake and would rather not weigh crackers.
- They travel. A packet survives a lunchbox, a desk drawer, a glovebox or a hospital bag in a way that a handful from a box does not.
- Serving other people. If you are putting soup in front of guests, patients or customers, sealed packets are the hygienic option.
What you give up
- Packaging. Forty wrappers is forty wrappers. If crispness is not a problem in your house because a box disappears in two days, the bulk box is the lower-waste choice.
- Cost per ounce. Single-serve packaging costs more to produce than one large bag, and that shows up in the price of any single-serve format.
How to store oyster cracker packets
Keep unopened packets somewhere cool and dry — a cupboard away from the stove is ideal, since heat and steam are what turn crackers soft. Because each packet is individually sealed, you do not need an airtight container for the box itself.
Once a packet is open, treat it like any opened cracker: eat it that day, or fold it shut and accept some loss of crunch. There is no preservative in the recipe to hold the texture. For the shelf life of the box itself, go by the best-by date printed on the packaging rather than a general rule of thumb.
What to eat them with
The classic pairings are the soupy ones — clam chowder, oyster stew, tomato soup, chilli, and any broth-based bowl where you want something crunchy that will not overwhelm it. They are also good crushed over a salad in place of croutons, floated on French onion soup, or eaten straight from the packet.
If you are building the soup itself from a bouillon cube, two of our other guides cover that side of the bowl: bouillon cube conversions, calories and sodium, and what to look for in a bouillon cube without added MSG.
Frequently asked questions
Do oyster crackers have oysters in them?
No. The ingredients are unbleached wheat flour, water, canola oil, salt, cane sugar, baking soda and yeast. There is no shellfish in them. The name refers to being served with oyster stew and chowder.
How many individual packets come in a box?
Forty, with 0.5 oz of crackers in each packet.
Are oyster crackers gluten-free?
No. They are made with unbleached wheat flour and carry a "contains wheat" declaration.
Are oyster crackers vegan?
The ingredient list — unbleached wheat flour, water, canola oil, salt, cane sugar, baking soda, yeast — contains no animal-derived ingredients. The pack does not carry a certified-vegan mark, so if certification matters to you rather than the ingredients alone, check the packaging directly.
How many calories are in oyster crackers?
45 calories per serving, along with 1 g of fat, 80 mg of sodium, 7 g of carbohydrates and 1 g of protein. The pack does not state the weight of one serving, so we cannot honestly convert that to a per-packet figure.
Are these oyster crackers non-GMO?
Yes — non-GMO, with no preservatives and no artificial additives.
How much sodium is in oyster crackers?
80 mg per serving, which is 3% of the daily value. That is on the low side for a savoury cracker.
The short version
Individually wrapped oyster crackers are a seven-ingredient wheat cracker, 45 calories and 80 mg of sodium per serving, sold 40 packets to a box at 0.5 oz each. They contain no oysters and no gluten-free credentials — wheat flour is the first ingredient. The single-serve wrapper is doing real work in a recipe with no preservatives in it, which is the main reason to choose the format.
