December 17, 2025 •

4 min read

Up to 30% of a watermelon's weight is its rind, a part often discarded but packed with nutrients like citrulline. This frequently overlooked portion can be boiled to create a healthy and refreshing herbal beverage, answering the question: yes, you can boil watermelon for tea, but it's the rind, not the flesh, that makes the best brew.

Quick Summary

Boil the nutritious watermelon rind to create a light, cucumber-flavored herbal tea. This zero-waste recipe is rich in vitamins, minerals, and citrulline, offering a healthy and refreshing drink.

Key Points

Rind, Not Flesh: You can boil watermelon for tea, but the recipe utilizes the white, inner rind rather than the sweet, red flesh.
Citrulline Boost: The rind is a rich source of citrulline, an amino acid known to improve blood flow and support athletic performance.
Cucumber-Like Flavor: The resulting tea is mild and refreshing, with a subtle taste similar to cucumber, which is perfect for hot or iced beverages.
Zero-Waste Cooking: Using the rind for tea is an excellent way to reduce food waste and extract additional nutrients from the entire fruit.
Simple Preparation: The process is straightforward, involving peeling, chopping, and simmering the rind in water to create a nutritious infusion.
Nutrient-Rich: Beyond citrulline, the rind tea contains significant amounts of vitamins (A, C, B6), minerals (potassium, magnesium), and fiber.

Beyond the Flesh: The Surprising Answer

Most people think of juicy, red flesh when they picture a watermelon, but the truth is the rind holds untapped potential, especially when it comes to creating a unique and healthy tea. While boiling the sweet, red flesh would simply result in hot juice with a slightly altered flavor profile, boiling the rind extracts beneficial compounds and creates a genuinely pleasant, herbal drink. This practice is a fantastic way to practice zero-waste cooking and unlock additional nutritional value from the fruit.

The Nutritional Powerhouse of Watermelon Rind

Far from being useless, the rind of a watermelon is a treasure trove of vitamins, minerals, and antioxidants. It is particularly known for its high concentration of the amino acid citrulline. Citrulline is an important compound that supports cardiovascular health and can aid in athletic performance by improving blood flow. Additionally, the rind contains a variety of other beneficial components:

Vitamins: Significant levels of Vitamins A, C, and B6 can be found in the rind. Vitamin C, for instance, boosts the immune system and aids in iron absorption.
Minerals: Essential minerals like potassium, magnesium, and zinc are present, which are crucial for hydration and metabolic function.
Fiber: The high fiber content supports digestive health, aids in bowel movements, and helps regulate cholesterol and blood sugar levels,.
Antioxidants: Compounds like flavonoids and lycopene in the rind offer anti-inflammatory properties and protect the body against free radicals.

How to Prepare Watermelon Rind Tea

Making your own watermelon rind tea is a simple and rewarding process. It can be enjoyed hot or chilled, and its flavor is surprisingly similar to cucumber, making it a refreshing, light beverage.

Prepare the Rind: Thoroughly wash the watermelon. Using a peeler or sharp knife, carefully remove the dark green outer layer, leaving only the white part of the rind.
Chop the Rind: Cut the white rind into small, manageable cubes or strips. For better extraction, you can shred the rind.
Boil: Add the chopped rind to a saucepan with water (a good starting ratio is 1 cup of rind per 2-3 cups of water). Bring the water to a boil, then reduce the heat and simmer for 20-30 minutes. Simmering ensures maximum flavor and nutrient extraction.
Strain and Serve: Strain the liquid to remove the rind pieces. You can drink the tea immediately while hot, or let it cool and refrigerate it for iced tea.
Flavor Variations: Enhance the mild flavor with additions like fresh mint leaves, a squeeze of lemon or lime juice, a few slices of ginger, or a cinnamon stick during the simmering process. Natural sweeteners like honey or agave can be added to taste.

Preserving and Using Rind Beyond Tea

If you have a large amount of rind, you can also dry it for later use. Drying the rind concentrates its flavor and nutrients and allows for long-term storage. Once dried, you can boil it as you would fresh rind. The leftover boiled rind can be used for other culinary creations, such as pickles or chutneys, soaking up the added spices beautifully. This ensures no part of the fruit goes to waste, maximizing your efforts and providing a sustainable cooking solution.
