My Personal Experience
The first time I made these, I was looking for a no-fuss keto lunch that didn’t require a stove or oven. I had a cucumber and some leftover tuna salad in the fridge. I scooped out the center, filled it up, and took a bite—and wow, I was hooked.
Since then, these stuffed cucumbers have become a go-to. They’re perfect for hot summer days, lazy weekends, or those times when you just want something light but satisfying. I’ve experimented with all kinds of fillings, and honestly, it’s hard to go wrong. The best part? They look fancy, but they’re ridiculously easy.
Required Equipment
🔪 Sharp Knife
You’ll need a sharp knife to cut the cucumbers cleanly in half lengthwise. It also helps when scoring and scooping out the centers.
🥄 Spoon or Small Scoop
Essential for removing the cucumber seeds and creating a little boat for the filling.
🥣 Mixing Bowl
Used to combine your filling ingredients. Go with a medium-sized bowl so you can mix easily without spilling.
🥄 Fork or Spatula
Helpful for mashing ingredients like tuna, eggs, or cream cheese into a smooth filling.
Ingredients & Substitutions
For the Base:
- 2 large cucumbers
These are your edible boats. English cucumbers work best for size and fewer seeds.
For the Filling (Tuna-Cream Cheese Version):
- 1 (5 oz) can tuna, drained
Adds protein and pairs perfectly with cucumber. You can also use canned chicken or salmon. - 3 oz cream cheese, softened
Creates a creamy texture. Can substitute with mashed avocado or Greek yogurt for a lighter option. - 1 tbsp mayonnaise
Adds moisture and richness. Optional if using creamy cheese already. - 1 tsp Dijon mustard
Brings in a tangy flavor kick. - 1 tbsp finely chopped red onion
Adds crunch and bite. You can use scallions or omit for a milder taste. - ½ tsp garlic powder
Rounds out the flavor. - Salt and pepper to taste
- Fresh dill or parsley (optional)
Herbs take it to the next level with freshness and color.
How to Make Keto Stuffed Cucumbers

Spoon the filling into the cucumber halves. You can be generous—pile it high! - Garnish (optional)
Sprinkle with extra herbs, paprika, or even a few crushed nuts for texture. - Serve chilled
These are best enjoyed cold for maximum refreshment.
Tips for This Recipe
- Use a paper towel to dry the cucumber boats before stuffing—this helps prevent sogginess.
- Softened cream cheese mixes more easily and gives a better texture.
- Make the filling ahead and store it in the fridge, then fill cucumbers when ready to eat.
- Chop your ingredients finely for a smoother bite and easier stuffing.
Optional Additions
- Chopped olives – For a salty, Mediterranean flavor.
- Grated cheddar or feta – Adds extra richness and flavor.
- Chopped pickles or jalapeños – For tang or heat.
- Everything bagel seasoning – A sprinkle on top takes these to a whole new level.
Serving Ideas

Storage Recommendations
- Fridge: Store leftover filling in an airtight container for up to 3 days.

- Not freezer-friendly: The cucumbers will become watery and lose texture.
Frequently Asked Questions
Can I use a different filling?
Absolutely! Egg salad, chicken salad, herbed cream cheese, or avocado mash all work beautifully.
Do I have to peel the cucumbers?
No, but you can if you prefer a more tender bite. English cucumbers have thin, edible skin.
What if I don’t like tuna?
Canned chicken, flaked salmon, or even a vegetarian cream cheese spread are all great alternatives.
Can I serve this warm?
This dish is best served cold or slightly chilled. Heating will cause the cucumber to release water.
