Tuna Salad Cucumber Boats
Made with dairy-free coconut milk yogurt and fresh cucumbers, this quick and easy dish is the perfect lightened up version of the classic tuna salad sandwich.
Packed with nutrition, this tasty lunch will also serve you with a hearty dose of heart-healthy omega-3’s and protein along with a wide variety of vitamins and minerals.
This recipe is naturally low in carbohydrates and high in quality protein and good fats. It is a perfect snack for weight loss or those who are watching their blood pressure levels.
When I cook with my sister who has type-1 diabetes, I always try and naturally cut down the number of carbohydrates in the meal in a realistic, delicious, way.
I have nothing against bread, but enjoying a cucumber ‘boat’ every once in a while is a great way to gently reduce your carbohydrate intake. It is also easy to make this snack or side dish so that it has a low amount of sodium.
Replacing bread with cucumber is especially beneficial if you are replacing refined white bread or working on managing a chronic health condition like diabetes.
Naturally Low-Carb Cucumber Boats
This tuna salad recipe features cucumbers instead of traditional bread or a wrap as the outside of the ‘sandwich’, which helps to reduce the number of carbohydrates consumed.
These cucumber boats are also an excellent way to enjoy an additional serving of vegetables during your day.
Depending on your age and gender, guidelines recommend that adults eat at least 1½ to 2 cups per day of fruit and 2 to 3 cups per day of vegetables as part of a healthy eating pattern. Studies show that having the recommended daily intake of fruits and vegetables can reduce the risk of most diseases.
This recipe can easily supply a cup of vegetables, while also providing vitamins, minerals and dietary fiber in a crispy, crunchy bite.
Nutrition Benefits of Cucumbers
Cucumbers are a delicious, plant-based vegetable that has many health benefits that contribute to an overall, well-rounded diet.
Cucumber calories are very low but that doesn’t mean they’re not packed with nutrients.
It is true that cucumbers are physically made up of more water than anything and they are one of the lower carb vegetables, but they are also very nutrient-dense, containing vitamins, minerals, antioxidants, and phytonutrients.

Fresh Organic Homegrown Cucumbers
This time of year I have so many fresh, homegrown cucumbers from my garden that I feel like I have to get creative to use them all up.
This is one of my favorite cucumber recipes because it is so light and refreshing and makes a perfect lunch, side dish or snack that even my kid will enjoy.
If you do not have a garden or access to a Farmers Market, you may want to consider purchasing organic cucumbers if you are concerned about pesticide use.
Cucumbers were placed on the Dirty Dozen list by the Environmental Working Group in 2016.
Tuna Salad Cucumber Boats By Diet
The beautiful part of this recipe is that you don’t really need to follow an exact recipe for it to be delicious.
You can truly make your tuna salad recipe however you traditionally make it and still enjoy it in a cucumber boat for added health benefits.
However, if you are looking for specifics by diet, you will find gluten-free, Paleo, and Keto friendly tuna salad cucumber boat options below:
Gluten-Free Diet Tuna Salad Cucumber Boat Option
Cucumbers are naturally gluten-free, meaning that you just need to be aware of the ingredients that you are using to make your tuna salad.
If you can verify that all of the ingredients used to make your tuna salad are clean, and ensure there was no cross-contamination in the kitchen, your tuna salad cucumber boats should be safely gluten-free.

Paleo Diet Tuna Salad Cucumber Boat Option
While most of the ingredients used in this recipe are natural, whole foods that are naturally Paleo friendly, store-bought mayo and the Greek yogurt are not.
The Paleo diet eliminates dairy, grains, and most processed ingredients like soybean oil and modified potato starch, found in most traditional, store-bought mayonnaise.
For most healthy individuals, these ingredients are not a problem, but for those suffering from an autoimmune or inflammatory condition, it may be helpful to eliminate them.
For the most part, the Paleo diet encourages homemade, whole food options, making any store-bought product off-limits, but there are varying degrees of how strict people choose to go Paleo.
I go more in-depth about what exactly the Paleo diet entails and why it may be helpful for the management of some health conditions in my first cookbook, The 30-Minute Thyroid Cookbook: 125 Healing Recipes for Hashimoto’s and Hypothyroidism.
To make this recipe Paleo friendly, you have three delicious options.
- Buy Paleo friendly mayonnaise from Primal Kitchen.
- Make your own Paleo-friendly mayonnaise using this recipe.
- Omit the mayonnaise and Greek yogurt altogether and substitute 1 whole peeled and pitted avocado. Combine all of the ingredients as you would normally, mashing with a fork until everything is well combined.
Keto Diet Tuna Salad Cucumber Boat Option
While I think that the Keto diet should be done under the supervision of a professional, I understand that people are looking for Keto recipes and this one fits the bill.
Cucumbers don’t have an exceptionally high amount of fiber and the amounts of carbs in cucumbers are relatively low, so the number of net carbs can be kept low with this snack.
This recipe contains 7 grams of carbohydrates and 2 grams of dietary fiber, leaving a total of 5 net carbohydrates.
Some Ketogenic diets limit net carbohydrates to as low as 20 per day, and again, this should only be attempted when working with a health professional.
The fats in cucumber boats can be controlled based on the mayonnaise you use or if you decide to add olive oil.
- 2 medium cucumber
- 2 cans wild-caught white albacore tuna, drained
- 2 stalks celery, diced
- ¼ cup white onion, finely diced
- ¼ cup dairy-free coconut milk yogurt
- ¼ cup mayonnaise
- 1 teaspoon yellow mustard
- ⅛ teaspoon of sea salt
- ⅛ teaspoon black pepper
- Slice the cucumbers down the middle length wise. Using a spoon, gently scrape out the insides.
- Discard (or compost) the scooped seeds and set the remaining cucumber aside.
- Add the tuna to a large bowl. Using a fork, gently mash the tuna until it is flaked.
- Add the celery, onion, yogurt, mayo, mustard, salt and pepper (and fresh herbs if you plan to use any).
- Mash all of the ingredients together with a fork until everything is mixed well.
- Scoop your fresh tuna salad mixture in each cucumber half.
- Top with sliced, homegrown tomatoes and additional salt and pepper to taste.
