These watermelon cocktails are the perfect way to cool down on a hot summer day. They're super easy to make and can be scaled up to hydrate a crowd. I've included a mimosa mocktail below as well so everyone can have a glass!
Key Ingredients
This homemade mimosa recipe only calls for 3 ingredients, with one of them being totally optional, as it depends on the sweetness of your watermelon!
- Watermelon: We'll be using fresh watermelon so we can make homemade watermelon juice! The redder your watermelon, the better and more naturally sweetened these drinks will be. Feel free to use store-bought watermelon juice.
- Vegan Champagne: Let's be honest, the champagne is the real star of mimosas. If you're not sure what alcohol is vegan, check out this website where you can check to see what brands (or which of their products, if any) are vegan-friendly.
- Agave: This is totally optional and only necessary if you find that your watermelon isn't giving you enough sweetness.
How to Make Watermelon Mimosas
It's super easy to make mimosas at home! If you host a brunch and make these, I fully expect an invite...kidding but kinda not?
- Add cubed watermelon to a high-speed blender and blend until smooth. I blended mine for 2 minutes and found this was the perfect amount of time.
- Place a fine mesh strainer over a pitcher and pour the watermelon juice through in order to separate any pulp or seeds. If it's slowed down quite a bit and there's a lot of pulp in the strainer, gently push it down and through with the back of a spoon.
- Divide (1) 750ml bottle of champagne amongst 4 to 6 champagne flutes, leaving enough room in each glass to add in the watermelon juice. I am leaving the amount of each completely up to you! I know some of you like 99% champagne, 1% juice while some of you like 50% champagne, 50% juice. If you have extra watermelon juice, you can drink it by itself or save it for another round.
- Garnish with a sprig of fresh mint and a watermelon slice and enjoy!
Recipe Variations
I love this recipe as is but here's a few ways you can spice it up!
- Make frozen mimosas by freezing the watermelon juice in an ice cube tray the night before you want to have the mimosas. The next morning, add your frozen watermelon juice ice cubes and champagne to a blender and blend until frosty yet drinkable. If it's too liquidy, add more ice cubes. If it's too frozen, add some more champagne or unfrozen watermelon juice.
- Add mint, cucumber, or basil to enhance the freshness of these mimosas. A cucumber watermelon mimosa sounds *chefs kiss* on a summer day.
- Use a different sparkling wine! You don't have to use champagne. Dry prosecco or Cava are both great options.
- Make a mimosa mocktail by replacing champagne with sparkling water!
Quick Tips
- Add the champagne first then add the watermelon juice. The cocktail will mix itself naturally.
- Drink straight away otherwise the watermelon juice will start to separate and sink to the bottom.
- Don't stir too much, really at all, as this will cause the champagne to go flat.
- Use cold champagne and cold watermelon. Mimosas don't typically have ice so make sure your ingredients are chilled to ensure these cocktails are as refreshing as possible. Chill the watermelon juice prior to adding it to the champagne flutes if needed!
- Make sure you strain the watermelon juice! There's nothing worse than unexpectedly drinking a big seed.
FAQ
I recommend choosing a dry sparkling wine. This could be brut champagne, dry prosecco, or cava. You usually add a sweet juice to mimosas, in our case watermelon, so a dry sparkling wine will help to balance out that sweetness.
There's so many options for vegan champagne! Some options include: Taittinger Brut Reserve, Moet & Chandon, Gloria Ferrer, and Veuve Clicquot Brut Champagne. Check out Barnivore.com to find more.
