This broccoli pasta salad recipe pairs tender rotini with fresh broccoli florets, sharp cheddar, crispy bacon, and a tangy-sweet mayo dressing. It comes together in 35 minutes, and the crunch from sunflower seeds and red onion holds up even after a day in the fridge.
Bring a large pot of salted water to a boil. Cook the rotini until al dente, about 9-11 minutes. Drain and rinse under cold water for 30 seconds until cooled. Shake well to remove excess water and transfer to a large bowl.
While the pasta cooks, wash the broccoli and cut the crowns into small, grape-sized florets. Rinse and dry thoroughly with a clean towel or salad spinner.
Heat a skillet over medium heat. Cook the bacon in a single layer until crisp and browned, about 6-8 minutes. Drain on a paper towel-lined plate and crumble into bite-sized pieces once cool.
In a medium bowl, whisk together the mayonnaise, apple cider vinegar, sugar, salt, and black pepper until completely smooth. Adjust sweetness or tang to your preference.
Add the dried broccoli, cubed cheddar, and red onion to the cooled pasta. Pour about three-quarters of the dressing over the top and gently toss until evenly coated. Fold in the bacon, sunflower seeds, and cranberries, reserving a little for garnish.
Cover the bowl and refrigerate for at least 30 minutes to let the flavors meld. Give the salad a quick toss before serving, then top with the reserved bacon, sunflower seeds, and cranberries.
Notes
Cut broccoli florets small and uniform so every bite has a balanced mix of ingredients.
Rinse pasta under cold water immediately after draining to stop cooking and prevent a mushy texture.
Add sunflower seeds and bacon right before serving if making the salad more than a few hours ahead, as they lose crunch in the dressing.
Always let pasta cool completely before tossing with the dressing to prevent the mayo from separating and turning greasy.
Salt the pasta water generously – it's the only chance to season the noodles themselves.
If the salad looks dry after chilling, stir in an extra spoonful of mayo before serving rather than adding vinegar.
Cube the cheddar instead of shredding it so the cheese stays distinct in every bite instead of clumping in the dressing.
Toast sunflower seeds in a dry skillet for 2-3 minutes for a deeper, nuttier flavor.
Store in an airtight container in the refrigerator for up to 4 days. Do not freeze.
For a lighter version, swap half the mayonnaise for plain Greek yogurt and reduce sugar by half.
