Most people think of Rice-A-Roni as a hot side dish, but it is genuinely one of the best bases for cold rice dishes and vermicelli salad recipes. Here is why:
This is the secret that makes Rice-A-Roni recipes like this one so craveable compared to generic salads with rice.
Having a large, sturdy mixing bowl and a proper whisk makes putting together the creamy dressing fast and easy, and a sharp chef's knife ensures your vegetables are evenly diced for the best texture throughout the salad.
The dressing is simple but it is everything. A base of mayonnaise and sour cream creates a tangy, rich coating that clings to every grain of rice and every piece of shrimp. Fresh lemon juice brightens it up and keeps it from tasting heavy, while a little garlic powder ties it all together.
Chef's Tip: Do not skip chilling the salad for at least an hour before serving. The rice and vermicelli continue absorbing the dressing as it rests, which is what transforms this from a good salad into a great one.
A few things make the difference between a good salad and one that disappears within minutes at your next potluck:
This recipe is wonderfully versatile, too. It fits comfortably among the best Salads For Dinner on a hot weeknight, holds its own at any potluck dish spread, and works just as well as a make-ahead lunch for the week.

This Cold Rice-A-Roni Shrimp Salad is the ultimate potluck dish, packed with tender shrimp, crisp vegetables, and a creamy tangy dressing over fluffy vermicelli rice.
Cook both boxes of Rice-A-Roni according to the package directions. Once done, spread the cooked rice and vermicelli mixture onto a large baking sheet and allow it to cool completely to room temperature, about 20 to 30 minutes. For faster results, refrigerate for 15 minutes.
While the rice cools, prepare your vegetables. Dice the celery and red bell pepper into small, even pieces. Thinly slice the green onions and chop the fresh dill. Thaw the frozen peas by placing them in a colander and running cool water over them, then pat dry.
In a large mixing bowl, whisk together the mayonnaise, sour cream, fresh lemon juice, garlic powder, salt, and black pepper until smooth and creamy. Taste and adjust seasoning.
Add the fully cooled Rice-A-Roni to the bowl with the dressing. Fold gently to coat without breaking up the rice too much.
Add the shrimp, celery, red bell pepper, green onions, thawed peas, and dill. Fold everything together carefully until evenly combined.
Cover the bowl tightly with plastic wrap and refrigerate for at least 1 hour before serving, or up to overnight. The chilling time allows the flavors to meld beautifully.
Before serving, give the salad a good stir, taste for seasoning, and add a splash more lemon juice if desired. Garnish with extra green onions or dill and serve cold.
Serving: Pile the salad into a wide, shallow serving bowl and top it with extra sliced green onions and a few sprigs of dill for a fresh, beautiful presentation. A squeeze of lemon right before serving adds a bright finishing note.
Storing: Keep leftovers tightly covered in the refrigerator for up to 3 days. The salad thickens overnight as the rice continues to absorb the dressing. Stir in a spoonful of mayo and a tiny splash of lemon juice to loosen it back up before serving again.
