Ingredients You’ll Need

The beauty of First Watch Kale Tonic lies in its handful of unpretentious ingredients, each playing a starring role in flavor and health. With just a few simple items, you’ll end up with a drink that’s fresh, energizing, and loaded with natural vibrancy—no fancy powders or syrups required. Here’s what you’ll need and why it matters:

Kale: The hero of this tonic, kale delivers deep, earthy notes and a beautiful green hue, plus heaps of nutrients.
Lemon (peeled): Adds brightness and a tangy lift that balances the greens and keeps every sip sparkling.
Apple (fuji or gala): Offers gentle sweetness and mellow fruitiness, smoothing out earthy flavors for a balanced tonic.
Cucumber: Brings clean, refreshing undertones that lighten up the blend and help quench your thirst.
Water: The simplest ingredient, but essential—thins the juice and makes the end result easy to drink.

How to Make First Watch Kale Tonic

Step 1: Wash and Prep the Produce

Start by giving your kale, apple, lemon, and cucumber a thorough rinse. Remove any tough stems from the kale, peel the lemon to remove bitterness, and core the apple if you like. Chop everything into smaller pieces—the smaller the pieces, the easier they’ll blend or juice, and the better the flavors will come together.

Step 2: Blend It All Together

For the classic homemade approach, combine all your washed and prepped produce in the blender. Pour the water over top—don’t worry, this helps everything blend smoothly and gives the tonic its signature drinkable consistency. Secure the lid and blend on high until the mixture is completely pureed, stopping to scrape down the sides or stir if needed. You want a smooth, green mash that smells bright and inviting.

Step 3: Strain to Perfection

Now it’s time to transform that emerald puree into a smooth, sippable tonic. Set a fine mesh strainer (or a double layer of cheesecloth) over a glass bowl. Carefully pour in the blended mixture, then use a spoon to press and squeeze out every bit of vibrant juice. Take a moment to admire that lush green color—it’s the best sign of all the goodness inside. Discard or compost the leftover pulp.

Step 4: Try the Juicer Method (Optional)

If you have a juicer, making First Watch Kale Tonic is even speedier! Cut your cucumber and apples into pieces that will fit inside. Slowly feed the kale, lemon, apple, and cucumber through your juicer, collecting the bright green juice below. Add the water to your finished juice, give it a stir, and you’re set. It’s as easy and tidy as it gets.

Step 5: Chill and Enjoy

This tonic is at its best served cold. Pour your juice over a glass of ice for a crisp, invigorating drink. The flavors will pop, and the cooling effect is just what you want first thing in the morning or on a sunny afternoon.

How to Serve First Watch Kale Tonic

Garnishes

A garnish isn’t just about looks—it actually makes each glass of First Watch Kale Tonic feel extra refreshing! Try a thin wheel of lemon perched on the rim, a sprig of fresh mint, or even a few matchstick apple slices for a pretty (and edible) touch. Garnishes add a festive note that turns your juice into something restaurant-worthy every single time.

Side Dishes

Looking to turn your tonic into a full meal or brunch spread? First Watch Kale Tonic pairs beautifully with a homemade frittata, smashed avocado toast, or a mezze platter with hummus and veggies. Anything that complements light, clean flavors is fair game here. For an on-the-go snack, a handful of granola or a fruit salad is a delicious match.

Creative Ways to Present

If you’re serving guests or just want to treat yourself, pour the First Watch Kale Tonic into clear glasses or mason jars so that gorgeous green color shines. Layer it with ice cubes of frozen apple juice for a pretty, ombre effect or serve in little shot glasses for a brunch “health booster” bar. Presentation is half the fun—it sets the mood for a meal that’s as energizing as it is delicious.

Make Ahead and Storage

Storing Leftovers

Fresh juice always tastes best within the first 24 hours, but you can absolutely make a batch of First Watch Kale Tonic to enjoy throughout the day. Simply store any leftover juice in an airtight container (a glass jar works perfectly) in the fridge. Give it a quick shake or stir before serving, since natural separation is totally normal and harmless.

Freezing

If you want to keep First Watch Kale Tonic on hand for longer, freeze the juice in individual portions—ice cube trays or silicone molds work great for this. Once frozen, pop the cubes out and transfer them to a freezer-safe bag. They’re perfect for tossing into your next smoothie or letting thaw in the fridge for a fresh glass later in the week!

Reheating

While reheating isn’t necessary for this type of fresh juice (and honestly wouldn’t do the flavors any favors), you can let it sit at room temperature for a few minutes if you don’t want it super cold. Just stir well and enjoy. For best taste, savor your First Watch Kale Tonic chilled or lightly cool from the fridge.

FAQs

Can I use a different type of kale?

Absolutely! Both lacinato (also known as Tuscan or dinosaur kale) and curly kale work wonderfully in First Watch Kale Tonic. You can even mix them if you’re feeling adventurous; each lends a slightly different texture and flavor profile, but both are delicious.

Is it necessary to peel the lemon?

Peeling the lemon helps remove any bitterness from the pith and rind, keeping your tonic tasting bright and smooth. If you like a touch of tartness, try adding a little bit of the peel, but for most palates, fully peeled lemon is best.

Can I substitute the apple variety?

Yes! While fuji and gala apples are favored for their natural sweetness and crispness, you can experiment with other apples you have on hand. Just make sure they’re sweet and juicy—the tartness of a Granny Smith might be too strong, but it’s always fun to play around!

What can I do with the leftover pulp?

Get creative—don’t toss that nutrient-rich pulp! It can be stirred into pancake batter, mixed into muffins or quick breads, or added to homemade veggie burgers for a fiber boost. Or, simply compost it and let your garden reap the rewards.

How can I make the tonic more filling?

If you want your First Watch Kale Tonic to keep you satisfied longer, blend in half a banana or a scoop of protein powder before straining. This adds creaminess and extra staying power, especially if you’re enjoying the tonic as breakfast or a snack.
