A cool, crisp smoothie that actually tastes like a spa day? That’s the cucumber mint combo. It’s hydrating, gentle on your stomach, and easy to make even on a busy morning.
This is the kind of drink that leaves you feeling light instead of weighed down. If you’re trying to reduce bloat or simply want a fresh, clean flavor, this is a smart pick. Plus, you only need a handful of ingredients and five minutes.
Why This Recipe Works

This smoothie leans on ingredients that are naturally hydrating and soothing.
Cucumber and mint bring a clean, cooling flavor that won’t overwhelm your palate early in the day. A squeeze of lemon brightens everything and helps balance the slight sweetness from fruit. Greek yogurt (or a dairy-free alternative) adds creaminess and protein so you’re not hungry an hour later.
The result is a smooth, refreshing blend that’s kind to your digestion and easy to sip.
What You’ll Need
- 1 medium cucumber, peeled if waxed and roughly chopped
- 1 small green apple or 1/2 ripe pear, cored and chopped (for natural sweetness)
- 1/2 cup plain Greek yogurt (or unsweetened coconut yogurt for dairy-free)
- 1/2 cup baby spinach (optional, for extra greens without changing flavor)
- 8–10 fresh mint leaves, stems removed
- 1 tablespoon fresh lemon juice (about 1/2 lemon)
- 1/2–3/4 cup cold water or unsweetened coconut water, to blend
- 4–5 ice cubes (more if you like it frostier)
- Pinch of sea salt (optional, to sharpen flavors)
- Optional boosters: 1 teaspoon chia seeds, 1 teaspoon grated fresh ginger, or a few slices of cucumber for garnish
Instructions

- Prep the produce. Wash everything well. Peel the cucumber if it has a waxy skin. Core the apple or pear.
Roughly chop for easier blending.
- Layer the blender. Add water (or coconut water) first, then cucumber, apple, yogurt, spinach, mint, lemon juice, and a small pinch of salt. Top with ice.
- Blend until smooth. Start on low and increase to high for 30–45 seconds. If it’s too thick, add a splash more water.
If it’s too thin, add a few more ice cubes.
- Taste and adjust. For more brightness, add another squeeze of lemon. For extra sweetness, add a couple of grape halves or a small piece of ripe pear. Keep it light, not sugary.
- Boost if you like. Blend in chia seeds or fresh ginger.
Give it 10–15 seconds to combine.
- Serve immediately. Pour into a chilled glass and garnish with a mint sprig or a thin cucumber slice.
Keeping It Fresh
This smoothie tastes best right after blending when the mint is most aromatic. If you need to make it ahead, store it in an airtight jar filled to the top to minimize air. Keep it in the fridge for up to 24 hours.
Give it a vigorous shake before drinking. For a grab-and-go option, prep smoothie packs: portion chopped cucumber, apple, spinach, and mint in freezer bags. In the morning, just add liquid, yogurt, and lemon, then blend.

Why This is Good for You
- Hydration first: Cucumbers are mostly water, which supports fluid balance and can help reduce water retention and bloat.
- Gentle on digestion: Mint and lemon are known for their light, soothing qualities.
They add flavor without heaviness.
- Balanced energy: Greek yogurt brings protein, helping you feel satisfied and steady. If you’re dairy-free, coconut yogurt keeps the texture creamy.
- Fiber matters: Apple and spinach add fiber, which supports regularity and a happy gut.
- Low added sugar: The sweetness comes from fruit, not syrups. That keeps it refreshing and clean.
Pitfalls to Watch Out For
- Over-sweetening: Adding honey, juice, or lots of sweet fruit can defeat the light, flat-belly feel.
Keep sugars modest.
- Too much mint: Mint is potent. Start with 8–10 leaves and adjust. Too much can make the smoothie taste like toothpaste.
- Skipping the acid: Lemon is small but mighty.
Without it, the flavor can taste flat and vegetal.
- Using warm ingredients: Room-temperature produce dulls the flavor. Use cold water and a handful of ice.
- Waxy cucumber skin: If your cucumber is waxed, peel it to avoid bitterness and residue.
Variations You Can Try
- Ginger Lime Kick: Swap lemon for lime and add 1 teaspoon grated fresh ginger for a zesty, tummy-soothing twist.
- Avocado Cream: Add 1/4 small avocado for extra creaminess and healthy fats. Reduce yogurt slightly to balance texture.
- Tropical Green: Replace apple with 1/4 cup pineapple or mango for a brighter, beachy flavor.
Keep portions small to control sugar.
- Protein Lift:-strong> Add a scoop of unflavored or vanilla protein powder. Increase liquid by 2–3 tablespoons to keep it smooth.
- Herb Garden: Add a few leaves of basil with the mint for a fresh, aromatic blend.
- Spirulina Glow: Stir in 1/2 teaspoon spirulina for minerals and a deeper green color. Flavor stays mild with the mint and lemon.
FAQ
Can I make this without yogurt?
Yes.
Use unsweetened coconut yogurt or skip yogurt and add 1/4 avocado for creaminess. You may need a bit more liquid to blend smoothly.
Is this good for weight management?
It can help as part of a balanced routine. The smoothie is low in added sugars, hydrating, and includes fiber and protein, which can help you feel satisfied.
Pair it with consistent meals, movement, and sleep for the best results.
What type of cucumber is best?
English cucumbers are great because their skins are thinner and less bitter. If using standard cucumbers with a waxy coating, peel them for cleaner flavor.
Can I use bottled lemon juice?
Fresh is best. Bottled juice can taste dull or bitter.
If you must use it, start with a small amount and taste as you go.
Will the spinach change the flavor?
Not much. A small handful blends in easily and mainly boosts color and nutrients. If you’re sensitive to greens, start with a quarter cup.
How can I make it sweeter without adding sugar?
Use a riper pear or a few seedless grapes.
You can also add a tiny piece of frozen banana, about one inch, to keep it balanced.
Can I add ice after blending?
It’s better to blend the ice in so the texture stays smooth. If you add ice after, the drink can separate faster.
Is coconut water necessary?
No. Plain cold water works perfectly.
Coconut water adds electrolytes and a hint of sweetness, but it’s optional.
