- → Can I make these taco shells ahead of time?
- Yes, you can prepare these shells up to 2 days in advance. Store them in an airtight container in the refrigerator with parchment paper between layers. Reheat them in a 350°F oven for 5-7 minutes until warm and crisp before serving.
- → What fillings work best with cauliflower taco shells?
- These shells work well with both traditional and creative taco fillings. Try ground beef or turkey with taco seasoning, grilled chicken or fish, roasted vegetables, black beans, avocado, fresh salsa, and a dollop of Greek yogurt instead of sour cream.
