Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep cauliflower from drying out.
Can I substitute ingredients in Creamy Cauliflower & Bacon Soup?
