This smoothie is bright green, genuinely sweet, and ready in five minutes flat. The lemon drop melon does most of the work — its citrusy flavour completely covers the spinach, so this is a solid option if you or your kids are skeptical of green drinks. One batch makes one serving, but the prep system behind it is what makes it worth building into your week.
Why this recipe works
Two things matter here. First, blending the spinach with the liquid before any frozen fruit goes in gives you a completely smooth result — no fibrous green flecks, no grassy texture. Spinach needs a few seconds of high-speed contact with liquid to fully break down, and frozen fruit added too early drops the temperature and thickens the blend before that happens. Second, using solidly frozen fruit instead of fresh fruit plus ice keeps the flavour concentrated. Ice dilutes as it melts; frozen melon and banana don’t. The result is a thick, cold smoothie that still tastes like fruit rather than watered-down fruit.
Smart swaps
- Lemon drop melon: This is a small yellow melon with a sweet, faintly citrusy flavour — not widely stocked year-round. The recipe card covers the honeydew-plus-lemon-juice swap, which works well. Canary melon is another close substitute if you can find it.
- Canned full-fat coconut milk: Shake the can before opening — the fat and liquid separate on the shelf. If you only have light coconut milk, the smoothie will be thinner and less filling. That’s fine, but worth knowing.
- Baby spinach vs. mature spinach: Baby spinach blends out almost completely. Mature spinach leaves have tougher stems and a stronger flavour; skip the stems if that’s all you have.
Common problems and fixes
- Smoothie turns grey or muddy instead of green: The banana is likely overripe with heavy brown spots. Very dark bananas add a lot of brown pigment. Use bananas that are ripe but still mostly yellow before freezing.
- Coconut milk fat is solid and won’t blend in: If the can has been stored somewhere cold, the fat solidifies into chunks. Scoop it into the blender first and let it sit for 60 seconds at room temperature before blending, or run the sealed can under warm water briefly.
- Smoothie is drinkable at first but turns thick and gluey fast: Frozen banana continues to thicken as it warms. Drink it within 10 minutes or keep the cup in a bowl of ice while you’re sipping.
- Spinach bits still visible after blending: Your blender may need a longer run on the liquid-and-spinach step. Give it a full 20 seconds rather than 10 before adding the frozen fruit — skip the garnish of extra spinach leaves on top, not worth the extra dish.
- Melon cubes clump into one frozen block: This happens when cubes are bagged while still slightly warm or damp. Dry the cubes with a paper towel and make sure they’re fully frozen solid on the sheet pan before transferring to bags.
Leftovers and make-ahead
The recipe card covers storing a single leftover serving for up to 24 hours, but the bigger time-saver is batch-prepping the frozen components. When lemon drop melon is in season or on sale, cube a whole melon, freeze the cubes flat on a lined sheet pan for at least four hours, then divide into individual one-cup portions across several freezer bags. Do the same with banana halves. Each bag holds one complete smoothie’s worth of fruit. Stored properly in sealed bags, frozen melon keeps well for up to three months and frozen banana for up to two months — after that, both are still safe but lose some flavour. On a busy morning, you grab one fruit bag, add spinach and coconut milk, and blend. No measuring, no prep. If you want to go further, add a measured cup of baby spinach to each bag before freezing; spinach freezes fine and blends out just as smoothly from frozen.
Green Kermie Smoothie: Melon & Spinach Breakfast
Equipment
- Blender (single-serve bullet-style or full-size countertop)
- Cutting Board and Knife
- Sheet pan (for freezing melon cubes flat)
- Freezer-safe bags or vacuum sealer bags
- Measuring cups
Ingredients
- ½ large banana frozen
- 1 cup lemon drop melon cubes frozen
- 1 cup baby spinach organic
- ¼ cup coconut milk canned, full-fat for creamiest results
- ½ cup water
- as needed ice for desired thickness
Instructions
- Add the coconut milk and water to your blender first, then the baby spinach. Blend for 10 seconds until the spinach is fully broken down. Add the frozen banana, frozen melon cubes, and a handful of ice. Blend on high for 30–60 seconds until completely smooth and creamy. If the smoothie is too thick, add water 1 tablespoon at a time.
Notes
- Storage: Pour any leftover smoothie into an airtight jar and refrigerate for up to 24 hours. Give it a vigorous shake or quick re-blend before drinking as separation is normal.
- Make-ahead: Pre-portion the banana, melon, and spinach into individual freezer bags so you can dump and blend on busy mornings.
- Substitutions: No lemon drop melon? Use honeydew melon cubes with a squeeze of fresh lemon juice for a similar bright flavour. Swap coconut milk for oat milk or almond milk if preferred.
- Boost it: Add a tablespoon of nut butter, a scoop of protein powder, or a tablespoon of chia seeds for extra staying power.
- Pro tip: Blend the spinach with the liquid first for 10 seconds before adding the frozen fruit for a silky-smooth texture.
- Substitution step (from original recipe): If you don’t have lemon drop melon, you can substitute honeydew and add a squeeze of fresh lemon juice.

Common questions
Can I use fresh melon instead of frozen?
You can, but the smoothie will be thin and won’t have the same thick, cold texture. If fresh is all you have, add a full cup of ice and expect a slightly more diluted flavour.
Will I actually taste the spinach?
No — the melon and banana cover it completely. The spinach contributes colour and nutrients but has almost no flavour impact in this ratio, especially once it’s fully blended with the liquid.
Can I make this the night before?
It’s better fresh, but it holds in the fridge for up to 24 hours in a sealed jar. Shake or re-blend it before drinking since the coconut fat and fruit solids will separate overnight.
Is canned coconut milk the same as the coconut milk in the refrigerated carton?
No — they’re very different products. Canned full-fat coconut milk is thick and rich, which is what gives this smoothie its body. The refrigerated carton version is mostly water and will produce a much thinner result.
My blender is small — will it handle frozen fruit?
A bullet-style blender like a NutriBullet handles this batch well since it’s a single serving. Add the liquid first so the frozen fruit isn’t sitting directly against the blade when you start, and blend in short pulses for the first few seconds.
