Creamy Butternut Squash and Sweet Potato Salad

A light, protein-boosted vegetable salad combining roasted butternut squash and sweet potatoes with a tangy Greek yogurt-mayonnaise dressing. Fresh celery, onion, and red bell pepper add crunch and color. Serve chilled as a side dish at summer barbecues, potlucks, or alongside grilled chicken. This version cuts calories by blending mayo with fat-free Greek yogurt while maintaining creamy richness.

  3. 3

    Cool until handleable, then drain excess water.

  4. 4

Tips

Tip 1

Microwave vegetables in a covered bowl with minimal water to retain nutrients and flavor while ensuring even cooking.

Tip 2

Cool cooked squash and potato completely before mixing with dressing to prevent dressing from breaking or becoming greasy.

Tip 3

Make ahead: refrigerate up to 3 days; flavors deepen as vegetables marinate in dressing.

Good to Know

Storage

Cover and refrigerate up to 3 days. Keep dressing and vegetables separate if storing longer than 1 day to prevent sogginess.

Make Ahead

Prepare vegetables and dressing separately up to 2 days ahead. Combine 2-4 hours before serving for best texture.

Serve With

Serve chilled as a side dish at room temperature or directly from the refrigerator. Pairs well with grilled chicken, fish, or as part of a vegetable-forward meal.

Common Mistakes

Watch

Microwave vegetables uncovered to avoid mushy texture; cover to ensure even, faster cooking.

Watch

Skip cooling vegetables before mixing dressing to prevent heat from breaking the mayo-yogurt emulsion.

Watch

Don't skip refrigeration; chilling allows flavors to meld and vegetables to absorb dressing.

FAQ

Can I make this salad ahead of time?

Yes. Prepare dressing and chop vegetables up to 2 days ahead. Combine 2-4 hours before serving for optimal texture. Full salad keeps 3 days refrigerated. If storing longer, keep components separate.

What if I don't have fat-free Greek yogurt?

Use full-fat Greek yogurt in a 3-to-4 ratio (use 3/4 cup full-fat for 1 cup fat-free), or substitute sour cream 1:1. Flavor deepens but calories increase slightly.

How long can I keep this refrigerated?

Cover and refrigerate up to 3 days. Vegetables soften over time as they absorb dressing. Texture is crispest in the first 24 hours.
