Keto Tuna Salad on Tomatoes
Thickly sliced tomatoes are the perfect summery base for this Keto Tuna Salad. Five minutes and five ingredients are all you need for this low-carb lunch or dinner.
When summer tomatoes are absolutely perfect and in season, one of my favorite ways to enjoy them is topped with my super simple tuna salad.
I love this recipe because it’s ready in 5 minutes, needs just 5 ingredients, and has the perfect fat and protein and low carb macros for keto.
Everyone has slight variations on their favorite tuna salad. But if you’re coming to my house, this is exactly how I make it and it’s pretty perfect.
I love sliced green onions because of their mild onion flavor. Then super finely chopped celery for crunch. A good amount of mayonnaise (nothing worse than a dry tuna salad!), and lots of freshly chopped dill.
The resulting tuna salad is juicy, flavorful and light tasting.
What to Serve Keto Tuna Salad On?
I’ve done my keto tuna salad in a bowl and scooped it up with celery, cucumbers, bell pepper, etc. It’s also delicious on butter lettuce, on romaine lettuce, or on keto bread.
My favorite way to enjoy it is on thickly sliced summer tomatoes. They add the perfect amount of acid to complement the tuna. Obsessed.

I LOVED this! Perfect texture and the dill was the perfect addition! We did it on crackers with tomatoes topped with the salad – so simple and so filling!
Oh, this makes me so happy! Such a quick and easy meal! I’m so honored!
Just made this for lunch and it was fabulous – a huge upgrade from the my typical, lackluster tuna sandwich. I tried half of the tuna salad on carbonaut gluten free toast with leafy romaine and tomato; the other half on salted, tomato slices. Loved both! Super fresh, uncomplicated and flavorful – doesn’t get any better than that 🤷♀️ This recipe will be going into my regular rotation. Thank you 🙌
Hi Paige! I am so glad you liked this recipe! Switching things up is so worth it. Happy lunching!
This falls into the “why didn’t I think of this” category. So simple yet so delicious!! We have a lot of tomatoes in the garden and this is a great way to use them . Fresh, healthy, delicious and easy. What’s better than that? Try it…..you won’t even miss the bread!
Hi Lisa! Isn’t it crazy how the bread isn’t missed at all? With super juicy, delicious tomatoes, you don’t even realize it’s gone! Love this. Thank you for being here!
