Is Strawberry Jam Gluten Free?

Yes, strawberry jam is gluten free. It's just fruit, sugar, and a gelling agent like pectin, so there's no wheat, barley, or rye in a standard recipe. The only real question is whether a specific brand backs that up with a formal label claim — here's how the major ones compare.

Gluten Content in Popular Brands

Good news first: strawberry jam is naturally low-risk for gluten, since it's just fruit, sugar, and a gelling agent like pectin. Still, formulations and formal label claims vary by brand, so here's what each one actually says.

Brand	Gluten Free?	Notes
Bonne Maman	Yes	Confirmed gluten free by the brand; their production facility is gluten free too.
Smucker's	Likely	No gluten-containing ingredients on the label, but Smucker's does not make a formal "gluten-free" claim — check the jar if you need certified GF.
Welch's	Yes	Brand states its fruit spreads, including strawberry, are gluten free.
Polaner	Yes	Labeled gluten free by the brand.
Trader Joe's	Yes	No gluten ingredients in either the regular or Organic Reduced Sugar Strawberry Preserves.
Knott's Berry Farm	Likely	Ingredients (strawberries, corn syrups, pectin, citric acid) don't contain gluten, but sources conflict on a formal GF claim — check the label.
Kraft Pure Strawberry Jam	Yes	No gluten ingredients on the label; made with fruit pectin. No formal GF certification, but nothing to flag.
Smucker's Sugar Free Strawberry Jam	Likely	Uses polydextrose and maltodextrin instead of sugar — both are typically corn-derived and gluten free, but this line isn't formally GF certified either.
Smucker's Simply Fruit (Spread)	Likely	A "fruit spread," not a jam — made with fruit syrup and natural flavor rather than pectin. No formal GF claim, so check the label if you're strict.
Great Value (Walmart) Strawberry Preserves	Check label	Ingredients don't list gluten, but the package allergen statement has noted possible traces of wheat from shared manufacturing lines.

Brands reformulate and change facilities, so always check the current label or the manufacturer's site before buying if you have celiac disease or a severe gluten sensitivity.

Thickeners and "Spreads": Where It Gets Complicated

Not every jar on the shelf is a straightforward jam. "Fruit spread" and "preserves" are different formulations, and the ingredient that varies most between them isn't the fruit — it's the thickener. Classic jam uses fruit pectin, which is gluten free. Some low-sugar and reduced-sugar versions swap in modified food starch, gelatin, or gums instead, and while these are almost always corn- or plant-derived (and therefore gluten free), the label won't always spell that out. If a product uses vague "natural flavor" wording with no gluten-free claim, like Smucker's Simply Fruit, it's not necessarily unsafe — it just means the brand hasn't gone through formal certification, so you're relying on the ingredient list rather than a stamped guarantee.

Ingredients Notes

Get all of the ingredient quantities in the recipe card at the bottom of the post 

• strawberries - fresh strawberries are the best for making jam with. We do not recommend using frozen strawberries as they could release water from being frozen and throw off the jam mixture and ability to set properly.
• sugar - white granulated sugar is what this recipe was tested with. If you wish to use another form of sugar, consult your resources to make sure it is safe
• lemon juice - we prefer to use lemon juice that has been freshly squeezed from a whole lemon 
• salt - table salt is what was used in this recipe

How to Make Gluten Free Strawberry Jam

1. Prep your fresh strawberries by removing the green tops. 
2. Over medium low heat in a saucepan, add strawberries, sugar, fresh squeezed lemon juice, and salt. Stir regularly as it all heats up and the sugar starts to dissolve.
3. After the sugar has completely dissolved, use a potato masher to mash the strawberries. Increase the heat to bring the jam to a low boil. Once it achieves a low boil, reduce the heat again to low and let the mixture summer until it reaches your desired thickness. 
4. Once it has reached your desired thickness, remove the sauce pan from the heat and let it cool. Transfer jam to jars and store. 

Storage

For best results, strawberry jam can be stored in your refrigerator in a jar for up to 3 months.
