My Personal Experience
I first made this tuna keto bowl when I needed a quick, no-fuss meal. I had some canned tuna, avocado, and a few other keto staples in my fridge, and I just started tossing things together. The result? A creamy, flavorful, and incredibly satisfying meal that didn’t feel like “diet food” at all. Since then, this has become one of my go-to meals, especially when I’m short on time but still want something nutritious and delicious.
Required Equipment
Mixing Bowl
A good-sized mixing bowl helps you combine all the ingredients easily. I prefer a deep one so nothing spills over the sides when mixing.
Fork or Spoon
Perfect for flaking the tuna and mixing everything together without making a mess.
Knife & Cutting Board
Essential for chopping avocado, cucumbers, and any other fresh ingredients you’re adding to the bowl.
Measuring Spoons
If you want to get the seasoning just right, a set of measuring spoons makes things easier.
Ingredients & Substitutions
- 1 can (5 oz) tuna in olive oil, drained – Tuna is the star protein here. If you prefer, you can use fresh-cooked tuna or even salmon as a substitute.
- ½ avocado, diced – This adds creaminess and healthy fats. You can swap it for extra olive oil or a dollop of sour cream if needed.
- ¼ cup cucumber, diced – Adds crunch and freshness. If you don’t have cucumbers, try bell peppers.
- 1 tbsp mayonnaise – Gives the bowl a rich, creamy texture. You can use Greek yogurt for a tangy twist.
- 1 tsp olive oil – Enhances the flavors and adds more healthy fats. Avocado oil works great too.
- ½ tsp lemon juice – A touch of acidity balances the flavors. Vinegar (like apple cider or rice vinegar) can work as a substitute.
- ½ tsp Dijon mustard – Brings a mild tangy kick. If you don’t like mustard, skip it or replace it with a pinch of garlic powder.
- Salt & pepper to taste – Essential for seasoning. Adjust based on your preference.
- ½ tsp everything bagel seasoning (optional) – A game-changer for added texture and flavor.
How to Make Low-Carb Tuna Keto Bowl
- Prepare the tuna – Drain the canned tuna and transfer it to a mixing bowl. Use a fork to flake it into smaller pieces.
- Add the avocado – Dice the avocado and add it to the bowl. If you like a creamier texture, mash some of it slightly.
- Mix in the cucumber – Chop your cucumber into small cubes and toss them in for crunch.
- Add the dressing ingredients – Stir in the mayo, olive oil, lemon juice, and Dijon mustard. Mix well until everything is evenly coated.
- Season – Sprinkle salt, pepper, and everything bagel seasoning (if using). Stir again to combine.
- Serve and enjoy! – You can eat this bowl on its own, over leafy greens, or with keto-friendly crackers.
Tips for This Recipe
- Use high-quality tuna for the best taste—tuna in olive oil gives extra richness.
- Chill before serving if you prefer a cold tuna bowl. Letting it sit in the fridge for 10-15 minutes enhances the flavors.
- Mash the avocado more if you want a creamier texture, or keep it chunky for more bite.
- Adjust the seasonings to your taste—add a pinch of cayenne if you want a bit of heat!
Optional Additions
- Chopped boiled egg – Boosts protein and makes it even more filling.
- Shredded cheese – A sprinkle of cheddar or Parmesan adds extra flavor.
- Keto-friendly hot sauce – For those who love a spicy kick.
Serving Ideas
- Serve over a bed of mixed greens for a tuna salad-style meal.
- Scoop it into lettuce wraps for a light, refreshing option.
- Pair it with keto crackers or cheese crisps for added crunch.
Storage Recommendations
- Store leftovers in an airtight container in the fridge for up to 2 days.
- If storing, add avocado right before serving to prevent browning.
- Stir before eating to redistribute the flavors.
