Tips For Perfect Keto Pizza Casserole Every Time
Keep moisture in check: Pat or wring cauliflower dry so your casserole isn’t watery. Choose low-sugar sauce: Aim for 4–6 grams net carbs per 1/2 cup. Cheese matters: Use low-moisture mozzarella for the best melt and fewer puddles. Rest before serving so slices hold together and flavors settle.
