Canning French Fries Ingredients
For the Fries
- Potatoes – Choose large baking russets for the best texture; peel and cut into uniform strips (½ to ¾ inch wide).
- Water – Soak the fry-shaped potatoes to remove excess starch, ensuring they crisp up perfectly during cooking.
- Salt – Add 1 tsp per quart jar or ½ tsp per pint jar to enhance flavor and maintain texture during canning.
For Packing
- Boiling Water – Fill jars with boiling water over the packed fries, ensuring they stay fully submerged while maintaining 1-inch headspace.
Step‑by‑Step Instructions for Canning French Fries
Step 1: Prepare the Potatoes
Start by peeling your large baking russet potatoes and cutting them into uniform fry-shaped strips, about ½ to ¾ inch wide. This consistency is crucial for even cooking and texture. Once cut, soak the fries in cold water to remove excess starch, allowing them to crisp beautifully during subsequent cooking.
Step 2: Soak the Potatoes
After cutting, place the potato strips in a large bowl, covering them with water. Change the water every 20 minutes for a total soaking time of at least one hour; for best results, soak overnight. This will ensure your fries stay crisp after pressure canning.
Step 3: Pack the Jars
Once soaked, drain and rinse the potatoes thoroughly. Using wide-mouth jars, start packing the fries tightly, leaving about 1-inch of headspace for expansion. For flavor enhancement, add 1 tsp of salt per quart jar or ½ tsp per pint jar.
Step 4: Add Boiling Water
Next, bring a kettle of water to a rolling boil. Once boiling, carefully pour it over the packed fries in the jars, ensuring they are fully submerged while still maintaining that crucial 1-inch headspace at the top. This step is vital for proper canning.
Step 5: Release Air Bubbles
Using a non-metal utensil or a bubble remover, gently press the fries to release any trapped air bubbles within the jars. Afterward, wipe the rims of each jar clean with a damp cloth to ensure a proper seal. Secure the jars with lids and rings, tightening just to fingertip snug.
Step 6: Process in Canner
Place the jars in your pressure canner and process according to your canner’s instructions. You will need to process at 10 pounds of pressure—35 minutes for pint jars and 40 minutes for quart jars—to achieve the ideal preservation for your canned French fries.
Step 7: Cool and Store
Once the time is up, let the pressure release naturally. Afterward, carefully remove the jars from the canner and place them on a towel-lined surface to cool completely. Check that the seals are tight before labeling your jars and storing them in a cool, dark place for future crispy snack enjoyment.

Make Ahead Options
Preparing these delightful canned French fries ahead of time is a smart choice for busy weeknights! You can soak and pack the fries in jars up to 24 hours in advance, ensuring they are chilled and ready to go. To maintain their crispy texture, soak the fries in water overnight (changing the water a few times) before packing them tightly into wide-mouth jars with the appropriate amount of salt. When you’re ready to enjoy your fries, simply add boiling water, seal the jars, and process in the pressure canner according to the instructions. This way, you’ll have perfectly preserved fries that taste just as delicious as freshly made, saving you time and effort during your meal preparations!
