Place strawberries and one rosemary sprig in the shaker. Muddle gently to release flavors.
Add simple syrup, lemon juice, and ice to the shaker. Shake for 10-15 seconds.
Strain the mixture into a champagne flute, filling it about halfway.
Top with Prosecco, pouring slowly to keep the bubbles.
Garnish with the remaining rosemary sprig.
Serve right away and enjoy!
Notes
This recipe makes one cocktail. Double or triple the amounts for more servings. Use chilled Prosecco for the best results.The drink tastes best when served right away, as the bubbles will fade over time.You can swap Prosecco for other sparkling wines like Champagne or Cava.For a non-alcoholic version, use sparkling water instead of Prosecco. Adjust the simple syrup to taste, depending on how sweet you like your drinks
