Make the creamy dressing: In a medium mixing bowl, whisk together the mayonnaise, fresh lemon juice, and kosher salt until completely smooth. The mixture should be thick but spoonable, with a tangy edge from the lemon. Taste the dressing and adjust the lemon or salt slightly if you like a sharper or more seasoned flavor, keeping in mind that the celery will dilute the intensity a bit.

Combine salad and coat evenly: Add the sliced celery to the bowl with the dressing. Using a spatula or large spoon, gently fold the celery into the mayonnaise mixture until every piece is well coated. You’re aiming for a thick, creamy white coating that clings to the pale green celery without pooling excessively at the bottom of the bowl.
Chill in a plastic container: Transfer the creamy celery salad to a clean plastic tupperware-style container with a tight-fitting lid, smoothing the top so it looks even. Sprinkle the surface generously with freshly cracked black pepper for a speckled, slightly rustic finish. Seal the container and refrigerate for at least 30 minutes, or up to several hours, to let the flavors meld and the celery chill thoroughly.

Serve and store: Just before serving, give the salad a gentle stir in the container to redistribute any dressing that has settled. Taste and add a pinch more salt or a squeeze of lemon if needed. Serve cold, straight from the tupperware for a casual gathering, or spoon into a serving bowl. Return any leftovers promptly to the refrigerator, keeping the lid on tight to maintain crunch and food safety.
Variations & Tips
To keep this salad true to its low-carb, four-ingredient spirit, treat add-ins as optional extras rather than essentials. For a touch of sweetness and contrast, you can fold in a few tablespoons of very finely diced red onion or a small handful of chopped celery leaves, but remember that each addition moves you beyond the original four-ingredient concept. If you prefer a slightly lighter dressing, replace 2 to 3 tablespoons of the mayonnaise with plain Greek yogurt; this keeps the creaminess and tang while trimming the richness.

For a more pronounced bite, substitute part of the lemon juice with apple cider vinegar, tasting as you go so the dressing doesn’t become too sharp. A pinch of garlic powder or onion powder can deepen the flavor without changing the texture. If you need this salad dairy-free, stick with a good-quality mayonnaise that contains no milk products and skip any yogurt substitutions.
Food safety tips: Always keep the salad refrigerated at 40°F (4°C) or below, since mayonnaise-based dishes can spoil if left at room temperature too long. At parties or potlucks, avoid letting it sit out for more than 2 hours total (1 hour if the room is very warm or the gathering is outdoors in summer). Use clean utensils each time you serve or taste the salad to prevent cross-contamination. Store leftovers in an airtight plastic container and enjoy within 2 to 3 days for best crunch and flavor; discard if there is any off smell, separation that doesn’t stir back together, or visible mold.
