Method
Cook and cool the pasta
- Cook penne pasta according to package directions, then drain and rinse with cold water to stop cooking and cool it quickly.
Make the Dijon dressing
- Whisk mayonnaise, sour cream, Dijon mustard, lemon juice, salt, and pepper until smooth and evenly combined.
Build the pasta salad (before chilling)
- Combine pasta, diced chicken breast, crumbled bacon, cherry tomatoes, and shredded cheddar in a large bowl.
Coat and chill
- Pour dressing over the salad and toss to coat so every piece is lightly covered.
Chill
- Refrigerate for at least 1 hour to let flavors meld.
Finish with lettuce
- Just before serving, add chopped romaine lettuce and toss to keep it crisp.
Notes
For best texture, rinse the pasta well with cold water and chill the salad before adding the romaine so the lettuce doesn’t wilt. Refrigerate leftovers in a covered container for 3-4 days; freeze is not recommended. For a lighter option, replace mayonnaise and sour cream with a reduced-fat mayonnaise or Greek-yogurt-based substitute while keeping the Dijon and lemon juice the same.
