Side Dishes
Canning squash for frying transforms seasonal produce into crispy, golden bites that stay fresh all year—this method preserves both texture and flavor perfectly. The secret lies in proper sterilization, precise packing, and pressure canning to ensure food safety while maintaining that tender-crisp quality.
I’ve tested this with yellow squash and zucchini, both of which fry up beautifully with a satisfying crunch.
What sets this recipe apart is the no-sog technique: a light coating of cornstarch before canning creates a barrier that keeps fried squash crispy, not greasy. The process requires just 30 minutes of prep followed by pressure canning (about 90 minutes), making it ideal for batch cooking.
Safety is critical—sterilized jars, proper processing times, and acidification (if needed) ensure your canned squash stays safe to eat for up to a year.
When frying, the results are restaurant-quality: golden, caramelized edges with tender centers that hold their shape. Pan-frying in oil at 350°F delivers a crispier finish, while deep-frying creates an extra-crunchy exterior. The no-sog secret means you’ll never deal with soggy, oil-soaked squash again—just perfect, crispy bites every time.
Perfect for meal prep, holiday sides, or quick weeknight dinners, these canned squash bites reheat beautifully and freeze well. Whether you’re preserving summer’s harvest or stocking your pantry for winter, this method ensures you’ll always have crispy, delicious squash ready to fry.

The squash and zucchini are the stars here—look for firm, heavy produce with vibrant color. Local farmers markets often have the freshest summer squash, but any grocery store’s produce section works if it’s labeled fresh. Avoid any with soft spots or wrinkled skin. I usually buy yellow squash and zucchini in equal parts—they handle canning and frying similarly, but the yellow variety has a slightly sweeter flavor. If you can’t find yellow squash, Italian heirloom zucchini works too, though it’s a bit milder. The key is freshness—these veggies are best canned within 2 days of purchase.
No cornstarch? Arrowroot powder works in a pinch, but it’s pricier. The lemon juice is critical for acidification—bottled lemon juice works if fresh isn’t available, but add an extra tablespoon to be safe. For the jars, Ball or Kerr brand are my go-tos—they’re tested for canning safety. If you’re short on jars, sterilize them in boiling water for 10 minutes instead of using a dishwasher cycle. The vegetable oil for coating? Any neutral oil (like canola or sunflower) works—just avoid olive oil, which has a low smoke point. And if you’re frying later, grab a deep fryer thermometer—350°F is key for that perfect crunch.
Canned squash keeps for up to a year in a cool, dark pantry, but trust me, it’ll disappear faster. Once opened, transfer to the fridge and use within 5 days. For frying, the no-sog secret means you can store them unrefrigerated for up to 3 months if you’ve got a root cellar or cool pantry. The flour dredge after canning? Optional, but it adds an extra-crispy layer when frying. I like to keep a stash of these in my freezer too—just thaw overnight before frying for best results.

Step-by-step instructions for canning squash for frying
Here's how to preserve summer squash for crispy, golden frying all year—no soggy results guaranteed.
Prepare and Blanch the Squash
Wash the 3 lb yellow squash and 3 lb zucchini thoroughly, then trim off the ends. Cut them into 1-inch thick slices—consistent thickness ensures even cooking. Place the slices in a large pot and cover with 12 cups water (enough to completely submerge them). Add the 1 tablespoon salt and the 0.25 cup lemon juice to the water.
Bring to a rolling boil over high heat, then reduce to medium-high heat and blanch for 2-3 minutes until the squash is just tender but still holds its shape. You'll know it's ready when a knife slides in easily but the center still offers slight resistance. Immediately drain the squash in a colander and plunge it into an ice bath made with the 2 cups ice cubes to stop the cooking process and preserve color and texture.
Create the No-Sog Cornstarch Coating
While the squash cools in the ice bath, mix the 0.5 cup cornstarch with 2 tablespoons vegetable oil in a large bowl until it forms a smooth, fine powder. The cornstarch creates a protective barrier that prevents sogginess during frying later. Drain the squash slices completely, then transfer them to the cornstarch mixture and toss gently but thoroughly to coat each piece evenly.
Spread the coated squash slices on a clean kitchen towel to dry for 10 minutes. This step is crucial—any moisture left on the squash will prevent the cornstarch from forming that crispy crust during frying. You'll see the slices become matte and dry to the touch, which means they're ready for the next step.
Pack and Process the Mason Jars
Fill each of the 12 whole pint-sized mason jars with the cornstarch-coated squash slices, packing them tightly but not mashing them. Leave about ½-inch headspace at the top of each jar. Wipe the rims with a damp cloth to ensure a clean seal, then place the lids and bands on each jar.
Process the jars in a boiling water bath for 45 minutes after the water returns to a full rolling boil. This sterilizes the jars and preserves the squash for up to a year. The cornstarch coating ensures the squash stays crispy when fried later—no soggy results here. Remove the jars and let them cool completely before storing in a cool, dark place.
Fry to Crispy Perfection
When ready to fry, remove a jar of squash and drain it thoroughly. Heat 3 cups vegetable oil in a deep fryer or heavy pot to 375°F. Fry the squash slices in batches for 1-2 minutes until they turn a beautiful golden brown color and float to the surface. You'll notice the cornstarch coating puff up slightly, creating that irresistible crunch.
Drain the fried squash on paper towels and immediately toss with the 0.25 cup all-purpose flour to maintain crispiness. Serve hot as an appetizer or side dish—each bite should deliver that satisfying crunch you're after. The lemon juice in the blanching water adds a subtle tang that pairs perfectly with the crispy exterior and tender interior.
Pro Tips For Making Canning Squash For Frying
- Cut Thin, Cut Even: Grab a sharp knife and slice squash and zucchini paper-thin—about ⅛-inch or less. I learned this the hard way when my first batch came out soggy because some pieces were uneven. A mandoline helps, but a steady hand works too—just don’t rush it.
- Salt Before Dredging: Toss sliced squash with salt first, then let it sit 10 minutes to draw out moisture. After burning through three batches of greasy, uneven fries, I finally realized this step makes the cornstarch cling better and cuts down on splatter.
- Fry in Batches: Crowding the pan? Bad idea. Fry squash in single-layer batches—even if it means two trips to the skillet. I used to ignore this and ended up with limp, half-cooked strips. Hot oil + space = crispy fries every time.
- Use Cold Oil: Heat oil to 350°F, but start with cold oil in the pan. Pouring hot oil over cold squash causes splattering chaos. Let the pan warm gradually—your future self will thank you when the kitchen stays dry.

Frequently asked questions
Can I use any type of squash for this canning method?
Yellow squash and zucchini work best due to their firm texture and mild flavor, which hold up perfectly when fried. Avoid overripe or seedy varieties—they won't crisp properly. For variety, try Italian heirloom zucchini, but stick to 1-inch thick slices for even cooking.
Why does the cornstarch coating prevent soggy results?
The cornstarch creates a protective barrier that absorbs moisture during canning and frying. When heated, it forms a crispy crust instead of letting the squash absorb oil and turn greasy. This "no-sog" secret keeps the texture perfect for up to 3 months when stored properly.
Do I need a pressure canner for this recipe?
No—a standard boiling water bath works perfectly for squash since it's a low-acid food. Process pint jars for 45 minutes after boiling begins. Just ensure your jars are properly sealed and headspace is ½-inch to prevent spoilage.
Can I freeze canned squash instead of canning it?
Yes! Skip the canning step and freeze the cornstarch-coated squash on a tray for 1 hour, then transfer to bags for up to 6 months. Thaw overnight before frying. Freezing preserves texture better than canning for some, but canned squash lasts 1 year in the pantry.
What's the best oil for frying canned squash?
Use a neutral oil with a high smoke point like vegetable, canola, or peanut oil. Heat to 375°F for golden, crispy results. Avoid olive oil—it burns easily and imparts a bitter flavor. For extra crispiness, try 325°F with panko breadcrumbs for a tempura-style finish.
