Mix the lime or lemon juice with the pickle juice, garlic powder, onion powder, paprika, salt, and pepper.
Add the Dijon mustard, mayonnaise, and sour cream.
Mix until smooth and creamy. You want everything fully combined here so the dressing is evenly seasoned before adding the tuna.
If it feels a little too thick, a small splash of pickle juice can loosen it slightly.
Add the tuna to te mixing bowl and start covering with the dressing.
Make sure the tuna is well-drained so the salad stays creamy instead of turning watery.
Gently mix the tuna into the dressing until it’s evenly coated.
Try not to overmix it here; you want to keep some larger pieces so the texture stays nice and not too mashed.
Add the chopped pickles, jalapeño, green onion, and fresh herbs. This is where the salad gets all of its crunch, freshness, and a little extra kick.
Fold everything together until well combined. The tuna should look creamy, textured, and evenly mixed with all the chopped ingredients throughout.
Serve over a bowl of greens with sliced cucumber on the side for scooping. The cucumber adds freshness and a little crunch, and it works really well with the creamy tuna salad.

Notes
This tuna salad is simple, but a few small details make a big difference in how it turns out. Once you’ve made it a couple of times, you’ll start adjusting it without even thinking about it.
Tuna: Make sure it’s well drained before mixing. Too much liquid will water everything down and the dressing won’t hold the same way.
Creamy base: The mix of sour cream, mayo, and Dijon keeps it balanced. If you prefer it lighter, you can reduce the mayo slightly and add a bit more sour cream.
Acidity: Lime and pickle juice are what keep this from tasting flat. Don’t skip them, and adjust to taste if needed.
Heat: The jalapeño is optional, but it adds a nice kick. Start small and adjust depending on your preference.
Storage: Keep it in an airtight container in the fridge for up to 3 days. It’s best within the first couple of days while it still tastes fresh and holds its texture.
Let the tuna salad sit for a few minutes before serving so the flavors come together and taste more balanced.
