This Tuna Egg Cottage Cheese Salad is creamy, fresh, and full of protein. The cottage cheese takes the place of most of the mayo you might find in a classic tuna salad, while chopped egg makes it extra filling. I love the little crunch from celery and red onion, too. Best of all, it comes together in about 15 minutes.
Why I Love This Recipe
I started making tuna salad with cottage cheese when I wanted something creamy without needing a big spoonful of mayo. At first, I thought the cottage cheese might stand out too much. Once it was mixed with tuna, Dijon, lemon, and dill, though, it made a lot of sense.
The egg makes the salad feel more like a full meal, while celery and onion keep each bite from feeling too soft. It is especially handy for lunch because there is no cooking when you already have hard-boiled eggs in the fridge.
- It takes only about 15 minutes.
- It has plenty of protein.
- Cottage cheese makes it creamy without making it heavy.
- Egg adds richness and makes the salad more filling.
- Celery and red onion give it a fresh crunch.
- Lemon and Dijon keep the flavor bright.
- It works for lunch, snacks, sandwiches, and meal prep.
Tuna Egg Cottage Cheese Salad Recipe
- Servings: 2
- Prep time: 15 minutes
- Cook time: 0 minutes when using already hard-boiled eggs
- Total time: 15 minutes
This recipe works best with cold, fully cooked hard-boiled eggs and tuna that has been drained very well.
What You’ll Need
- 1 can (5 ounces) tuna packed in water, drained very well
- 1/2 cup cottage cheese
- 2 large hard-boiled eggs, peeled
- 1/4 cup celery, finely diced
- 2 tablespoons red onion, finely diced
- 1 teaspoon Dijon mustard
- 1 teaspoon fresh lemon juice
- 1/8 teaspoon fine salt
- 1/8 teaspoon ground black pepper
Tools:
- Medium mixing bowl
- Cutting board
- Chef’s knife
- Measuring cups
- Measuring spoons
- Fork
- Large spoon or silicone spatula
- Can opener, if needed
Step 1: Flake the Tuna
Put 1 can (5 ounces) drained tuna into a medium mixing bowl. Use a fork to break it into small flakes. Do not mash it into a paste. Leaving some small chunks gives the salad a better texture.
Step 2: Add the Cottage Cheese and Seasonings
Add 1/2 cup cottage cheese, 1 teaspoon Dijon mustard, 1 teaspoon fresh lemon juice, 1/8 teaspoon fine salt, and 1/8 teaspoon ground black pepper to the flaked tuna. Stir gently until the tuna is coated and creamy.
Step 3: Chop the Eggs
Place 2 peeled large hard-boiled eggs on the cutting board. Chop them into small bite-size pieces. Keep the pieces chunky enough that you can still see the white and yellow yolk.
Step 4: Add the Crunchy Ingredients
Add the 2 chopped hard-boiled eggs, 1/4 cup finely diced celery and 2 tablespoons finely diced red onion to the creamy tuna mixture. Fold everything together gently with a large spoon or silicone spatula. Stop once the ingredients are evenly mixed so the eggs do not get mashed.
Step 5: Serve
Give the salad one final gentle stir. Spoon all of the finished Tuna Egg Cottage Cheese Salad into a round serving bowl. Serve right away, or chill it first if you like your tuna salad extra cold.
Why This Recipe Works (Quick Science)
Tuna and hard-boiled eggs can both feel a little dry on their own. Cottage cheese adds moisture, protein, and creamy curds that coat the tuna.
Dijon mustard helps bring the wet ingredients together while adding a little sharp flavor. Lemon juice adds acid. That acid cuts through the rich egg yolk and cottage cheese, making the whole salad taste fresher.
There is also a texture trick here. Soft tuna, creamy cottage cheese, and tender eggs are balanced by crisp celery and red onion. That mix of creamy and crunchy keeps each bite interesting.
Pro Tips
- Drain the tuna really well. Extra water can make your salad thin and watery.
- Use cold eggs. Warm hard-boiled eggs can soften the cottage cheese and change the texture.
- Dice the onion finely. Small pieces give you onion flavor without a huge bite of raw onion.
- Fold in the eggs gently. Stirring too hard can turn the yolks into a paste.
- Give it a short chill. If you have time, 15 to 30 minutes in the fridge helps the flavors come together.
Substitutions and Variations
- Swap fresh dill for 1 teaspoon dried dill.
- Use green onion instead of red onion for a milder flavor.
- Replace Dijon mustard with regular yellow mustard.
- Add diced cucumber for extra crunch.
- Add chopped pickles or 1 tablespoon pickle relish for a tangy version.
- Add a pinch of smoked paprika for a deeper flavor.
- Use lactose-free cottage cheese if needed.
- For a smoother salad, briefly blend the cottage cheese before adding it.
Make Ahead Tips
You can make this salad up to a day ahead. Keep it covered in the refrigerator until you are ready to eat.
For the crispest texture, you can also chop the celery and red onion ahead of time and keep them in separate containers. Fold them into the salad shortly before serving.
Common Mistakes
- Not draining the tuna enough: This is the biggest cause of watery tuna salad.
- Using too much lemon: A little wakes up the flavor. Too much can make the cottage cheese mixture thin.
- Overmixing: Gentle folding keeps the egg pieces and tuna flakes intact.
- Cutting the onion too large: Big pieces of raw onion can overpower the other flavors.
- Adding extra salt too quickly: Tuna and cottage cheese can already contain quite a bit of sodium. Taste before adding more.
What to Serve With
This salad is great on its own, but you can also serve it with:
- Whole-grain toast
- Crackers
- Pita bread
- Toasted English muffins
- Lettuce cups
- Cucumber slices
- Tomato slices
- A simple green salad
- Avocado
- A baked potato
It also makes an easy tuna sandwich or wrap filling.

Leftovers and Storage
Keep leftover Tuna Egg Cottage Cheese Salad in an airtight container in the refrigerator. For the best taste and texture, eat it within 2 to 3 days.
Give it a gentle stir before serving because a little liquid may collect at the bottom.
Do not leave the salad at room temperature for more than 2 hours, or more than 1 hour in very hot conditions. I do not recommend freezing it. Cottage cheese, eggs, and celery can all develop an unpleasant texture after freezing and thawing.
FAQ
Q: Can I use cottage cheese instead of mayo in tuna salad?
A: Yes. Cottage cheese makes tuna salad creamy while also adding protein. Its texture is different from mayo, so you will still see some small curds.
Q: Can I blend the cottage cheese first?
A: Yes. Blend the 1/2 cup cottage cheese until smooth before adding it if you want a more mayo-like texture.
Q: What kind of tuna works best?
A: Tuna packed in water works very well because the cottage cheese already brings plenty of moisture. Drain it very well before mixing.
Q: Can I use canned tuna packed in oil?
A: Yes. Drain it thoroughly. The finished salad will taste a little richer.
Q: Can I leave out the onion?
A: Yes. Simply skip it, or use finely sliced green onion for a milder taste.
Q: Why did my tuna salad turn watery?
A: The tuna may not have been drained enough, or the celery may have released some water. Very wet cottage cheese can also make the salad looser.
Q: Can I make this high-protein salad ahead of time?
A: Yes. It keeps well in a covered container in the refrigerator for 2 to 3 days.
