How to Make Zucchini and Banana Bread in a Jar Recipe
Step 1: Prep and Prepare Your Jars
Preheat your oven to 325°F (165°C). While it heats up, wash your Mason jars and lids thoroughly, then sterilize them to make sure your baked goods stay fresh and safe inside. This step is important to preserve the shelf life and guarantee a clean, beautiful presentation.
Step 2: Mix the Zucchini and Banana Batters Separately
In separate bowls, prepare your zucchini bread batter and banana bread batter. Combining these two gives you the opportunity to enjoy distinct flavors and textures in each jar, whether you layer them or swirl them together—both ways are delicious!
Step 3: Fill the Jars with Batter
Pour your batters into the sterilized jars, filling each about halfway. You can either layer the zucchini and banana batters for a striped effect or mix them lightly for a marbled look. This step is where your creativity shines, making each jar uniquely yours.
Step 4: Bake Until Perfectly Cooked
Place the jars on a baking sheet and bake for 40 to 45 minutes, or until a toothpick inserted in the center comes out clean. The slow baking ensures even cooking while the jars retain moisture, resulting in a soft, tender crumb that’s hard to resist.
Step 5: Seal and Cool
As soon as the baking time is up, remove your jars from the oven and immediately seal them with their lids while still hot. Allow them to cool completely at room temperature. This method locks in freshness and creates a wonderful, airtight container for your bread.
Step 6: Store and Enjoy
Your sealed jars can now be stored at room temperature for several months, making them perfect for gifts or for keeping a ready supply of homemade bread on hand anytime you need a comforting bite.
How to Serve Zucchini and Banana Bread in a Jar Recipe

Garnishes
Adding a simple garnish can elevate your presentation and add extra flavor. Consider a dollop of whipped cream, a sprinkle of powdered sugar, or a drizzle of honey or maple syrup on top of the open jar just before serving to add sweetness and visual interest.
Side Dishes
Pair your bread-in-a-jar with fresh fruit, a side of creamy yogurt, or even a small bowl of nut butter for dipping. These accompaniments create a balanced snack or a nutritious breakfast that’s as satisfying as it is delicious.
Creative Ways to Present
These jars are perfect for gifting or special occasions. Dress them up with a raffia ribbon around the neck, attach a handwritten label or tag with the recipe’s name, or include a little wooden spoon tied on for instant readiness. They’re charming, portable, and guaranteed to impress.
Make Ahead and Storage
Storing Leftovers
If you have any jars left after your first round of enjoyment, no worries! The sealed jars keep wonderfully at room temperature for weeks. Just make sure to store them away from direct sunlight and in a cool, dry spot.
Freezing
You can freeze your bread-in-a-jar if you want to extend the shelf life even further. Simply wrap the sealed jar in a layer of foil or place it inside a freezer bag to protect against freezer burn. When ready to eat, thaw it overnight in the fridge and enjoy the freshness as if it were just baked.
Reheating
To enjoy your zucchini and banana bread warm, remove the lid and microwave the jar on medium for about 20-30 seconds. Alternatively, you can pop the jar in a low oven (around 300°F) for 10-15 minutes. Just be sure to take off the lid before reheating to avoid pressure buildup.
FAQs
Can I use other types of squash instead of zucchini?
Definitely! Yellow squash or even grated carrot can work well in this recipe, but zucchini offers the best moisture and subtle flavor that complements the bananas beautifully.
Is it necessary to sterilize the jars before baking?
Yes, sterilizing ensures your jars are free of bacteria and safe for storing baked goods. It also helps create a vacuum seal when you close the lids hot, preserving freshness.
Can I make this recipe vegan?
You can substitute the egg with a flax egg or chia egg, and use plant-based oil and butter alternatives. Keep in mind that texture and taste might differ slightly but will still be delicious.
How long does the bread keep once opened?
Once opened, it’s best to consume the bread within a few days or refrigerate it to maintain freshness. Always check for any signs of spoilage before enjoying.
Can I double the recipe for larger batches?
Absolutely! Just make sure to have enough jars and adjust baking times slightly if necessary, keeping an eye on the bread’s doneness with a toothpick test.
