Rosemary Gin Fizz

Get ready for your new favorite keto cocktail! This drink has everything–Sweetness from the monk fruit, “earthiness” from the rosemary, tartness from the lemon juice, and a light boozy flavor from the gin! Even people who aren’t big gin fans should try it; the flavors all shaken together become a VERY delicious sip!

This drink starts with a special homemade sugar-free rosemary syrup. You only need three ingredients–Liquid monk fruit sweetener, rosemary, and water! After you try this syrup, you’ll definitely want to start growing your own rosemary! I can’t wait to try this syrup in more cocktails and maybe even as a glaze for muffins.

Another thing you’ll love about this keto drink: It goes with SO many different foods! From a summer poolside party spread to a traditional holiday buffet, this delicious cocktail will complement savory and sweet recipes!

Ingredients for a Sugar-Free Gin Fizz

As always, this is a quick overview of what you’ll need. Keep scrolling down to the printable recipe card for exact measurements!

• Gin
• Lemon juice : I used freshly squeezed lemon juice, but bottled is fine, too.
• Keto rosemary simple syrup : The recipe is below. You’ll need water, fresh rosemary, and liquid monk fruit sweetener.
• Lemon soda water : I used lemon Bubly drops with my soda stream, but store-bought or plain soda water is fine, too
• Ice
• Garnish ideas: Rosemary springs, lemon wedges or twists

Rosemary Sugar-Free Simple Syrup

This simple syrup is so easy! In a small pot, bring 1/4 cup rosemary leaves (stripped from the stem), 1 cup of water, and 1 tablespoon of monk fruit liquid sweetener to a simmer. Allow to simmer 10-15 minutes, then take off of heat to cool for 10 minutes. Pour through a fine mesh strainer, and store strained syrup in the fridge up to one month.

Can I use granulated monk fruit with erythritol?

I have not had success using blends with erythritol to make a simple syrup. Unfortunately, it does not fully dissolve; Once your syrup returns to room temperature, the erythritol begins to crystallize. I have read that adding a pinch of xanthan gum can prevent this, but I haven’t tried this method.

Bonus perk of using liquid monk fruit sweetener: it can be added by the drop to drinks, so people who like their drinks sweeter can easily adjust the flavor! This is awesome for carrying in your purse to sweeten ice teas or coffee.

How to make a Rosemary Gin Fizz

This simple keto cocktail starts in a shaker–Combine ice, gin, lemon juice, and rosemary simple syrup. Shake for 30 seconds or until extremely cold. Pour over ice into a 12-ounce glass, then top with about 3 ounces of lemon soda water. Garnish with a rosemary sprig and a lemon slice for a beautiful, aromatic, delicious low-carb drink!

What to serve with a Rosemary Gin Fizz

This drink is incredibly versatile because the flavors are very balanced and complementary to tons of different kinds of foods! The rosemary and lemon pair wonderfully with Italian and French cuisine especially. Gin can adapt so easily, it works well with sweets, spice, even floral notes!

Keto Appetizers for Gin Fizz Cocktails

If you’re making a cheese board, this citrusy gin cocktail will pair great with gouda and brie (these Cherry Brie Bites would be amazing)! This Marinated Mozzarella uses a lot of herbs that would complement the drink as well. Charcuterie meats like prosciutto and cured hams work well with the herby flavor… Consider serving it in an Antipasto Salad for a different twist! 

More appetizers that would work: Italian Stuffed Mushrooms (prosciutto & mozzarella goodness), Keto Popcorn Shrimp (smoky and light), or lamb souvlaki and vegetables dipped in Keto Tzatziki (works great with the citrus and herbs).

Keto Dinners for Gin Fizz Cocktails

This Rosemary Gin Fizz would complement white meat and fish, especially with strong herb or citrus flavors. I can highly recommend Lemon Garlic Fish with Toasted Pine Nuts with Keto Roasted Radishes or Chicken Piccata with a side of Italian Baked Mushrooms.

While this drink is perfect for summer, it also would be perfect at the holiday table! This would be fantastic with a Roast Chicken, Easy Keto Stuffing, Low Carb Cranberry Sauce, and Rosemary Garlic Keto Dinner Rolls! 

Desserts to serve with a Rosemary Gin Fizz

Berries, white chocolate, and citrus flavors will be perfect with this gin fizz! Keto Fruit Pizza, Cheesecake Strawberries, and Keto Cheesecake with Strawberry Sauce would be excellent! If you prefer cheesecake bars, consider serving with this Lemon Blueberry version, Cranberry version, or Strawberry version! 

Keto cookies you could serve: Strawberry Thumbprint Cookies, Lemon Cookies (or this version with white chocolate and macadamia nuts), Orange Creamsicle Cookies, White Chocolate Macadamia Nut Cookies
