1-First Step: Cook the pasta Start by bringing a large pot of salted water to a boil. Add 2 cups elbow macaroni and cook until al dente, which usually takes about 7 to 8 minutes. You want the pasta tender but still firm, since it will soften a little more once it chills in the dressing. When the pasta is done, drain it right away and rinse it under cold water. This stops the cooking process and cools the pasta fast. It also helps keep the macaroni from clumping together.

2-Second Step: Mix the dressing In a medium bowl, whisk together 1/2 cup mayonnaise, 1 tsp Dijon mustard, and 1 tbsp white wine vinegar until smooth. The dressing should look creamy and fully blended. If it seems too thick, you can whisk in a tiny splash of cold water, but only if needed. This is the point where the flavor starts to come alive. The mayo gives the salad body, while the mustard and vinegar add a bright tang that keeps each bite balanced.

3-Third Step: Prep the vegetables Add 2 stalks celery, 1 cup red bell pepper, and 1/4 cup red onion to the bowl. Stir them into the dressing so every piece gets a light coating. The vegetables should stay crisp, since that gives the salad its fresh texture and keeps it from feeling heavy. If you want a little more color, make sure the red bell pepper is diced evenly. Small, even pieces help the salad look neat and make it easier to serve at cookouts, lunches, or family dinners.

4-Fourth Step: Add the pasta Fold the cooled pasta into the bowl with the dressing and vegetables. Use a spoon or spatula and turn the mixture gently until the macaroni is coated evenly. Try not to stir too hard, because that can break the pasta and make the salad dense. Once the pasta is fully mixed in, taste the salad. Add salt and freshly ground black pepper to taste. Start with a small amount, then adjust slowly. This keeps the seasoning balanced instead of too salty or too sharp.

5-Fifth Step: Chill the salad Cover the bowl and refrigerate the macaroni salad for at least 30 minutes. This resting time lets the flavors blend and helps the texture settle. If you have more time, chilling it a bit longer is fine and often makes the salad taste even better.

6-Final Step: Garnish and serve Just before serving, sprinkle 1 tbsp parsley or chives on top. This adds a fresh finish and makes the dish look brighter. Serve the salad cold with grilled meats, sandwiches, burgers, or picnic plates. If you are making this for a gathering, transfer it to a clean serving bowl and give it one gentle stir before placing it on the table. That final mix brings the dressing back together if it has settled a little in the fridge.
