Quick Answer
It is not necessary to thaw frozen fruit before adding it to Jello. The frozen fruit can be added directly to the Jello as it sets. As the Jello sets up, the frozen fruit will thaw and incorporate nicely.
What Happens When You Add Frozen Fruit to Jello?
Jello is a gelatin dessert made by dissolving gelatin powder in hot water. As the Jello cools, the gelatin proteins link together to form a 3-dimensional matrix that gives Jello its signature jelly-like texture.1
When making Jello, fruits and other mix-ins can be added either before or after the Jello begins to thicken. If frozen fruit is added to hot, liquid Jello, the fruit will begin to thaw and release some of its juice into the Jello as it sets. This can lend nice fruit flavor to the Jello.
Importantly, the frozen fruit will continue thawing gradually as the Jello sets up and reaches refrigerator temperature. So by the time the Jello is fully set, the fruit will be completely thawed and incorporated.
Benefits of Adding Frozen vs. Fresh Fruit
There are a couple advantages to using frozen over fresh fruit in Jello:
- Convenience – No need to wash, peel, slice, or juice fresh fruit.
- Consistency – The fruit is already preprocessed so pieces are uniform in size.
- Stays firm – Frozen fruit holds its shape better when thawed in Jello vs. fresh fruit which can become mushy.
- Year-round – Frozen fruits allow you to make exotic Jello flavors any time of year.
The main downside to frozen fruit is that the texture may be slightly softer compared to fresh. But the convenience often outweighs this factor for Jello recipes.
Tips for Adding Frozen Fruit to Jello
Here are some tips to incorporate frozen fruit into Jello successfully:
- Use Within Recommended Time – Be sure to add the frozen fruit within the package instructions for setting the Jello. If fruit is added too late, the Jello may not set properly.
- Quick Thaw First – For larger frozen fruit like strawberries or grapes, run them under cool water for 1-2 minutes to thaw surface ice crystals. This prevents them from sticking together in the Jello.
- Cut Large Pieces – Cut large frozen fruit like peach slices into smaller pieces so they distribute nicely when suspended in the Jello.
- Account for Extra Liquid – Compensate for any extra fruit juice released by reducing the amount of cold water added by 2-4 tablespoons.
- Gently Stir – After adding fruit, gently fold to distribute rather than stirring vigorously which can cause fruit to clump.

Recipe: Strawberry Banana Frozen Fruit Jello
Here is a festive and fruity Jello recipe using frozen banana and strawberries:
Ingredients:
- 1 (3 oz) package strawberry Jello
- 1 cup boiling water
- 1 cup cold water
- 1 cup frozen strawberries
- 1 frozen banana, sliced
Directions:
- Dissolve the Jello powder in 1 cup boiling water. Stir for 2 minutes until completely dissolved.
- Add 1 cup cold water and stir again. Refrigerate for 15 minutes until slightly thickened.
- Meanwhile, let the frozen strawberries and banana sit at room temperature for 5 minutes to thaw slightly.
- Gently fold the sliced banana and strawberries into the thickened Jello.
- Refrigerate for at least 4 hours until fully set before serving.
The natural pectin in the strawberries helps the Jello set up nicely. The banana lends creaminess while retaining shape when suspended in the Jello. Feel free to substitute other frozen fruit combinations.
Can You Use 100% Frozen Fruit?
While we don’t recommend using only frozen fruit in Jello without any added cold water, it is possible to create a 100% frozen Jello. The fruit must be thawed completely and mashed first to release all moisture and juice.
Then the measured fruit juice can be heated to a simmer and the Jello powder dissolved in the hot juice. For 1 cup of juice, use about half a 3 oz package of Jello powder. Pour into a mold, dishes, or freeze in popsicle molds.
The concentration of fruit will be higher and the natural pectin can help it set up firm. But the texture may be less smooth than typical Jello.
Should You Avoid Any Frozen Fruits in Jello?
Most frozen fruits work well in Jello as they thaw. A couple exceptions are:
- Melons – Watermelon, honeydew, cantaloupe have high water content. They can make Jello watery if added in too large a ratio.
- Citrus fruits – Oranges, lemons, limes contain acids that can impede Jello from setting properly.
We recommend using no more than 1/2 cup of diced frozen melon or a teaspoon or two of frozen lemon/lime juice per 3-oz package of Jello powder. Test a small amount first before making large batches.
Storing Jello with Frozen Fruit
Homemade Jello containing frozen fruits should be stored in the refrigerator per the package instructions, typically 3-4 days. The fruits will stay nicely suspended in the set gelatin.
For longer storage, molded Jello salads or parfaits with frozen fruit can be frozen up to 2-3 months. Thaw overnight in the refrigerator before serving.
Freezing allows you to make ahead for parties or prepare in batches. Just avoid freezing in metal pans which can cause discoloration over time.
Conclusion
Adding frozen fruit to Jello is an easy way to create flavorful, fun recipes. There’s no need to thaw first – the fruit will incorporate nicely as the Jello sets up.
Use packaging time guidelines, cut large pieces, compensate for extra juices, and gently fold in fruit. Pair complementary flavors and get creative with combinations. Frozen fruit Jello makes for a cool, refreshing treat any time of year.
