Zucchini bread jam is a delightful, spiced preserve inspired by the warm flavors of classic zucchini bread. This unique jam combines shredded zucchini, apples, and cozy spices to create a spread that tastes like a slice of homemade zucchini bread in a jar. It’s a perfect way to use up extra garden zucchini, and it transforms simple toast, yogurt, or even pancakes into something special.
Ingredients
- 3 cups shredded zucchini (packed, about 2 medium zucchini)
- 2 cups peeled, grated apple (about 2 medium apples)
- 1 tablespoon lemon juice (bottled for acidity)
- 1/4 cup water
- 1 package (1.75 oz) fruit pectin (such as Sure-Jell Original)
- 1 tablespoon ground cinnamon
- 1/4 teaspoon ground nutmeg
- 1/4 teaspoon ground cloves
- 1/2 teaspoon salt
- 4 cups granulated sugar
- 1 cup packed light brown sugar
- 1 teaspoon pure vanilla extract
Instructions
- Prepare produce: Wash the zucchini and apples. Trim ends from zucchini, peel apples, and core them. Shred both using a box grater or food processor. Measure after shredding and lightly pack into measuring cups.
- Start the base: In a large, deep non-reactive pot (at least 6-quart), combine the shredded zucchini, grated apple, lemon juice, and water. Stir well. Place over medium heat and cook, stirring occasionally, until the mixture starts to release juices and soften, about 5-7 minutes.
- Add pectin and spices: Sprinkle the pectin evenly over the zucchini-apple mixture. Add cinnamon, nutmeg, cloves, and salt. Stir until thoroughly combined and no lumps of pectin remain. Bring the mixture to a simmer, stirring often.
- Add sugars: Increase heat to medium-high. Add both granulated and brown sugar all at once. Stir until dissolved. Bring the mixture to a full rolling boil (one that doesn’t stop bubbling when stirred) over high heat, stirring constantly.
- Boil and thicken: Once boiling, continue to cook at a rolling boil for 1-2 minutes, stirring constantly, until the jam thickens slightly. Remove from heat. Stir in the vanilla extract.
- Test for set: Place a small spoonful of jam on a chilled plate. Let sit for 1 minute, then run your finger through it. If it wrinkles and holds its shape, it’s ready. If not, return to the heat and boil for 1 more minute, then retest.
- Jar the jam: Ladle hot jam into clean jars, leaving 1/4-inch headspace. Wipe rims, apply lids, and screw bands on fingertip tight. For refrigerator storage, let cool, then refrigerate immediately. For shelf-stable storage, process jars in a boiling water bath for 10 minutes (adjusting for altitude as needed), following safe canning guidelines for jams with added lemon juice.
- Cool and store: Let jars cool undisturbed for 12-24 hours. Check seals before storing. Refrigerate any unsealed jars and use within 3 weeks.
Tips
- Substitutions: If you don’t have apples, pears work well and add a delicate flavor. For a lower-sugar jam, use a low-sugar pectin and follow the package directions for altered ratios.
- Grating texture: Shredded zucchini and apple should be fine but not mushy; avoid over-processing in a food processor, which can make the jam watery.
- Storage: For refrigerator jam, use within 3 weeks. Properly canned and sealed jars keep up to 1 year in a cool, dark place.
- Common mistakes: Don’t skip the lemon juice—zucchini is low acid and needs the added acidity for safe canning. Always bring the jam to a full rolling boil after adding sugar for proper setting.
Serving Suggestions
- Spread on warm toast, English muffins, or bagels for a cozy breakfast treat.
- Swirl into plain Greek yogurt or cottage cheese for a spiced, sweet boost.
- Serve with pancakes, waffles, or French toast instead of syrup.
- Use as a filling for thumbprint cookies or sandwich between shortbread for a unique dessert.
- Pair with cream cheese on crackers for a simple appetizer.
Variations
- Nutty Zucchini Bread Jam: After the jam is cooked and removed from the heat, stir in 1/2 cup finely chopped, toasted walnuts or pecans for crunch (store refrigerated, as nuts can reduce shelf life).
- Vegan version: This recipe is naturally vegan as written, but you can use organic sugars if you prefer.
- Spice it up: Add 1/4 teaspoon ground ginger or a pinch of cardamom for a more complex spice profile.
- Citrus twist: Replace half the lemon juice with orange juice and add 1 teaspoon orange zest for a brighter, fruitier flavor.
- Chunky jam: For more texture, reserve 1/2 cup of shredded zucchini and apple, add them in after boiling, then simmer for just 1 minute before jarring.
Storage and Reheating
Once cooled and sealed, store unopened jars of zucchini bread jam in a cool, dark pantry for up to 12 months. After opening, keep refrigerated and use within 3 weeks for the best flavor and safety. If you make refrigerator jam (not processed in a water bath), always keep it chilled and consume within 3 weeks. Do not freeze in glass jars unless they are freezer-safe; alternatively, portion jam into freezer containers, leaving at least 1/2 inch of headspace, and freeze for up to 6 months. To use, thaw overnight in the refrigerator. Jam does not need reheating, but you can gently warm it in the microwave for a few seconds to soften if desired.
Frequently Asked Questions
- Can I make zucchini bread jam without pectin?
- While you can make a jam without commercial pectin, the set will be softer and the yield slightly less. You can simmer the mixture longer to thicken, but be aware that zucchini and apples are relatively low in natural pectin, so the texture may be more like a thick sauce than a traditional jam.
- Is this jam safe to can at home?
- Yes, but only if you follow proper canning procedures. The addition of bottled lemon juice ensures the jam is acidic enough for safe water bath canning. Always use tested recipes and do not alter the ratio of zucchini, apples, lemon juice, or sugar, as these are critical for safety.
- Can I reduce the sugar in this recipe?
- For a lower-sugar version, use a low- or no-sugar pectin and follow its instructions carefully. Do not simply reduce the sugar in the original recipe, as it can affect the set and safety of the jam. The standard recipe relies on sugar both for preserving and texture.
- My jam didn’t set—what can I do?
- If your jam is runny after cooling, you can re-cook it. Return the jam to a pot, add a little more pectin (about 1 tablespoon, mixed with a tablespoon of sugar), bring to a rolling boil for 1 minute, and test the set again before re-jarring. Alternatively, use the softer jam as a dessert sauce or yogurt topping.
- How do I know if my canned jam is sealed properly?
- After jars have cooled for 12-24 hours, press the center of each lid. If it doesn’t flex or pop, the jar is sealed. If it moves, refrigerate and use within 3 weeks. Never consume jam from jars with bulging lids, leaks, or off smells.
- Can I double the recipe?
- It’s best to make jam in single batches as written. Doubling can lead to uneven cooking, inconsistent set, and risk of scorching. If you want more jam, prepare separate batches rather than combining all ingredients at once.
