How to Make Watermelon Sorbet 

Prepare the Watermelon

• Cut the watermelon into bite-sized cubes, removing any seeds if needed.

Freeze the watermelon

• Spread the watermelon cubes in a single layer on a baking sheet lined with parchment paper. Freeze for at least 4 hours or overnight, until completely solid.

Chef's Tip: Freezing the watermelon in a single layer prevents the cubes from sticking together and helps them blend more evenly later.

Blend the sorbet

• Transfer the frozen watermelon cubes to a food processor or high-speed blender. Add the banana, lemon or lime juice and the honey or maple syrup (if using).
• Blend until smooth and creamy. If the mixture struggles to blend, add 1-2 tablespoons of water to help it along.

Adjust sweetness

• Taste the sorbet and add more honey or maple syrup if needed, blending briefly to combine.

Serve and Enjoy

• Scoop the sorbet into bowls and garnish with fresh mint leaves. Serve immediately for the best texture.

Chef's Tip: If the sorbet softens while blending, place it in the freezer for 20-30 minutes to firm up before serving.

Blender vs Food Processor: Which Works Best?

Both a blender and food processor can be used to make this blender watermelon sorbet, but they work a little differently.

A food processor is usually the easiest option because it blends frozen watermelon with less added liquid. This helps keep the texture thick and scoopable.

A high-speed blender also works well, especially if it has a tamper. You may need to add 1-2 tablespoons of water to get everything moving, but try not to add too much or the sorbet can become watery.

Flavor Variations, Substitutions and Add-Ins

This easy watermelon sorbet is simple, but you can adjust it depending on what you have on hand.

• Add strawberries - Replace up to half of the watermelon with frozen strawberries for a delicious watermelon-strawberry sorbet variation.
• Blend in fresh herbs - Add a few mint leaves or basil leaves while blending for an extra layer of fresh summer flavor.
• Booze it up - Add a splash of tequila or vodka for an adult version that's perfect for summer entertaining.

Storage Instructions

• Freezer: This watermelon sorbet is best enjoyed straight after blending, while it has a soft and creamy texture. Leftovers can be stored in a freezer-safe container for up to 1 month.
• Before serving: If the sorbet has been frozen for longer, it will become quite hard. Let it sit at room temperature for 5-10 minutes before scooping.

Chef's tip: Press a piece of parchment paper directly onto the surface before freezing. This helps reduce ice crystals and keeps the texture smoother.
