Method
Cook and cool the pasta
- Bring a large pot of water to a boil, then cook penne pasta according to package directions until al dente. Drain and rinse with cold water, then shake off excess moisture.
Make the Dijon dressing
- Whisk mayonnaise, sour cream, Dijon mustard, lemon juice, salt, and pepper until smooth and well combined. Stop when the dressing looks glossy and evenly colored.
Assemble (before chilling)
- In a large bowl, combine pasta, diced cooked chicken breast, crumbled bacon, cherry tomatoes, and shredded cheddar. Toss gently so the cheese and bacon are distributed throughout.
- Pour the dressing over the salad and toss to coat every piece of pasta. The salad should look lightly creamy rather than dry.
Chill
- Refrigerate the salad for at least 1 hour to firm up the flavors. Cover and keep it cold until ready to finish.
Finish just before serving
- Add chopped romaine lettuce just before serving, then toss again until evenly mixed. Serve immediately so the lettuce stays crisp.
Notes
Pro tip: rinse the penne with cold water and keep the romaine for the final toss—this prevents soggy lettuce. Store covered in the refrigerator up to 3 days; the texture softens over time, but it’s still good for leftovers. Freezing isn’t recommended due to lettuce and dairy dressing. For a lighter option, swap mayonnaise for Greek yogurt (same amount) to reduce fat while keeping the creamy tang.
