Ingredients

For the Salad Base

3 cups elbow macaroni (uncooked) (approx. 12 oz / 340 g)
1 cup sharp cheddar cheese, diced into neat ¼-inch cubes
½ cup red bell pepper, finely diced
½ cup green bell pepper, finely diced
½ cup English cucumber, seeded and diced
½ cup cherry or grape tomatoes, cut crosswise into halves
½ cup pitted black olives, drained and sliced
½ cup pitted green olives (manzanilla or castelvetrano), drained and sliced
¼ cup red onion, finely diced (submerged in ice water for 5 minutes, then drained)

For the Creamy Dressing

¾ cup whole-egg mayonnaise (quality brand preferred)
¼ cup sour cream (or full-fat Greek yogurt)
1 tablespoon Dijon mustard (or classic yellow mustard for traditional deli flavor)
1 tablespoon freshly squeezed lemon juice (or apple cider vinegar)
1 teaspoon pure honey (or granulated sugar, to round out acidity)
½ teaspoon garlic powder
½ teaspoon freshly cracked black pepper
½ teaspoon onion powder (optional, adds depth)
½ teaspoon fine sea salt, plus more to taste
2 tablespoons fresh flat-leaf parsley, finely chopped (optional garnish)

Step-by-Step Instructions

Step 1: Cook and Cool the Macaroni

Fill a large stockpot with 4 to 5 quarts of water. Set over high heat and bring to a rolling, vigorous boil.
Add 1 to 2 tablespoons of kosher salt to the water once boiling. Stir in the 3 cups of uncooked elbow macaroni.
Boil according to the package instructions, aiming strictly for al dente (typically 8 to 9 minutes). Test a piece around minute 7: the center should offer a clean bite without being chalky or soft.
Pour the cooked pasta into a colander in the sink. Immediately run cold tap water over the pasta for 60 to 90 seconds, gently lifting and shaking the colander to stop the residual cooking process completely.
Shake vigorously to dislodge excess water trapped inside the elbows. Let the macaroni sit in the colander for 10 minutes to drain fully and air-dry; damp macaroni dilutes the dressing.

Step 2: Prep the Vegetables and Cheese

While the pasta cools, prep the vegetables on a clean cutting board. Maintain a uniform dice (approx. ¼-inch) across the red bell pepper, green bell pepper, and cucumber so every forkful offers balanced texture.
Slice the cherry tomatoes in half through the stem line. If using larger cherry tomatoes with excessive liquid seeds, gently tap them on a paper towel to remove moisture.
Slice the black and green olives into uniform rounds.
Finely dice the red onion. Pro tip: Place diced red onion in a small bowl filled with ice water for 5 minutes, then drain thoroughly. This strips away harsh sulfur compounds, keeping the onion crisp and sweet without overpowering the salad.
Cut the sharp cheddar block into uniform ¼-inch cubes. Avoid pre-shredded bagged cheese, as cubed cheese provides distinct bites of creaminess.

Step 3: Whisk the Emulsified Dressing

In a medium mixing bowl, add ¾ cup mayonnaise and ¼ cup sour cream.
Add 1 tablespoon Dijon mustard, 1 tablespoon fresh lemon juice, 1 teaspoon honey, ½ teaspoon garlic powder, ½ teaspoon onion powder, ½ teaspoon black pepper, and ½ teaspoon fine sea salt.
Use a balloon whisk to beat the mixture vigorously until entirely uniform, glossy, and pale yellow.
Taste the dressing directly: it should taste slightly punchier and saltier than desired for an isolated sauce, as the unseasoned pasta and raw vegetables will temper its intensity once tossed. Adjust salt or lemon juice if necessary.

Step 4: Assemble the Salad

Transfer the thoroughly drained, cooled elbow macaroni into your largest mixing bowl.
Scatter the cubed cheddar cheese, diced bell peppers, diced cucumber, halved cherry tomatoes, sliced black olives, sliced green olives, and drained red onion evenly over the macaroni.
Scrape approximately three-quarters of the prepared dressing over the pasta mixture using a silicone spatula.
Using an under-and-over folding motion, gently toss until the pasta, vegetables, and cheese are evenly coated in a silky layer of dressing. Hold back the remaining quarter of dressing to freshen the salad after chilling.

Step 5: Chill and Marinate

Cover the bowl tightly with plastic wrap or a secure lid.
Transfer to the refrigerator for a minimum of 45 to 60 minutes (ideally 2 to 4 hours). As the salad chills, the starches in the macaroni absorb the acid, seasoning, and aromatics from the dressing, while the vegetables maintain their snap.

Step 6: Final Toss and Presentation

Remove the bowl from the refrigerator 10 minutes prior to serving.
Inspect the moisture level: chilled macaroni naturally absorbs surface fat and moisture. Stir in the remaining dressing (or a splash of milk/cream) to restore a glossy, rich coating.
Taste and adjust seasoning with an extra pinch of black pepper or salt if needed.
Transfer to a chilled serving platter or decorative salad bowl. Garnish the surface with finely chopped fresh flat-leaf parsley and a light dusting of smoked paprika. Serve cold.

Comprehensive Storage and Make-Ahead Guidelines

Make-Ahead Strategy: This salad is ideal for preparing up to 24 hours in advance. Prepare the pasta and mix-ins, fold with two-thirds of the dressing, cover, and chill. Reserve the remaining third in a small mason jar in the fridge. Fold in the reserved dressing 15 minutes before serving to revive the freshly made sheen.
Refrigeration: Store any leftovers in an airtight glass or BPA-free plastic container at or below 40°F (4°C). Properly stored, the salad remains fresh and safe for 3 to 4 days.
Reviving Next-Day Leftovers: Chilled pasta continues to absorb moisture overnight. If leftovers appear dry, stir in 1 tablespoon of mayonnaise mixed with 1 teaspoon of milk, buttermilk, or lemon juice to instantly restore the emulsion.
Freezing Warning: Do not freeze this salad. Mayonnaise and sour cream break upon thawing, leading to an oily, curdled texture, while celery, cucumber, and cooked pasta turn watery and mushy.
