Equipment

  • Large pot for boiling pasta
  • Colander
  • Mixing bowls
  • Whisk
  • Spoon or spatula

Ingredients
  

  • 4 cups elbow macaroni (uncooked)
  • 1 cup sour cream
  • ½ cup mayonnaise
  • 2 cups sharp cheddar cheese (cubed or shredded)
  • 1 cup peas (fresh or frozen)
  • 1 cup diced bell peppers
  • ½ cup diced red onion
  • 1 tsp garlic powder
  • Salt and pepper, to taste
  • Optional garnish: fresh parsley or chives

Instructions
 

  • Cook pasta: Boil macaroni in salted water until al dente. Drain and rinse under cold water to stop cooking.
  • Prepare dressing: In a bowl, whisk together sour cream, mayonnaise, garlic powder, salt, and pepper until smooth.
  • Add cheese and vegetables: Stir in cheddar cubes, peas, peppers, and onions.
  • Combine: Add cooled pasta to the dressing mixture. Toss until evenly coated.
  • Chill: Cover and refrigerate for at least 1 hour to allow flavors to meld.
  • Serve: Garnish with fresh herbs or extra cheese before serving.
  • Expert Tip: Rinse pasta under cold water immediately after cooking to prevent clumping and keep salad light.

Notes

  • Whole wheat pasta adds fiber and nuttiness.
  • Greek yogurt can replace sour cream for a lighter version.
  • Shredded cheddar blends more evenly, while cubes add texture.
  • Best served chilled; do not freeze as dressing may separate.
  • Adjust seasoning after chilling, as flavors intensify over time.
