FAQs
Can I use fresh cauliflower instead of frozen cauliflower rice?
Yes, you can pulse fresh cauliflower florets in a food processor to make cauliflower rice. Be sure to remove excess moisture by lightly steaming or sautéing before combining with the other ingredients.
Is this casserole very spicy?
The heat level depends on how many jalapeños you add and the buffalo sauce you choose. Start with the recommended amount and adjust to taste by adding more jalapeños or a spicier buffalo sauce if you prefer more kick.
