Substitutions and Variations
This smoothie is flexible and easy to adjust. You can replace green apple with a few pineapple chunks for a slightly sweeter flavor. If you prefer a milder taste, reduce the mint slightly.
For a creamier texture, add 1/4 avocado. You can also use unsweetened almond milk instead of water for a richer base. If fennel is not available, celery can provide a similar crisp freshness.
To increase protein, add unflavored protein powder. For extra fiber, include ground flaxseed. Keep flavors balanced so the mint and fennel remain the stars.
Make Ahead Tips
You can chop fennel, cucumber, and apple ahead of time and store them in airtight containers in the refrigerator. This saves time during busy mornings.
Chia seeds and flaxseed can be measured into small containers in advance. Smoothie packs with fennel, cucumber, and apple can also be stored in the freezer.
The Fennel Mint Detox Smoothie can be blended and stored in an airtight jar in the refrigerator for up to 24 hours. Shake well before drinking. If it thickens, add a splash of cold water and stir until smooth again.
Instructions
Step 1: Prepare the Ingredients
Wash and chop the fennel bulb, cucumber, and green apple. Remove any tough outer fennel layers. Measure the water, mint leaves, lemon juice, chia seeds, and ice cubes. Having everything ready makes blending easy.
Step 2: Blend Fennel and Liquid
Pour the cold water or coconut water into the blender. Add the chopped fennel and fennel fronds if using. Blend on high speed for 45 to 60 seconds until smooth.
Step 3: Add Remaining Ingredients
Add the mint leaves, chopped cucumber, green apple, lemon juice, chia seeds, and ice cubes. If using ginger, flaxseed, or protein powder, add them now. Secure the lid tightly.

Blend on high speed for 60 to 90 seconds. Stop and scrape down the sides if needed. The Fennel Mint Detox Smoothie should look smooth and evenly blended.

Leftovers and Storage
Store leftover Fennel Mint Detox Smoothie in an airtight jar or bottle in the refrigerator for up to 24 hours. Some separation is normal due to the fresh ingredients and chia seeds.
Shake or stir well before drinking. The smoothie may thicken slightly as it sits because the chia seeds absorb liquid. Add a splash of cold water and mix until smooth again.
