Frequently Asked Questions

Why use cream cheese in keto alfredo sauce?

Cream cheese acts as a natural stabilizer and thickening agent. Without wheat flour or cornstarch, cream cheese binds heavy cream and melted parmesan into a luscious sauce that will not separate in the oven.

Can I use frozen broccoli and cauliflower?

Yes, but thaw completely and squeeze out all excess moisture with a clean dish towel before assembling the casserole, or your alfredo sauce will turn thin and watery.

How many net carbs are in a portion of this alfredo bake?

Each generous serving contains only 5g net carbohydrates (8g total carbs minus 3g dietary fiber) and delivers 41g of high-quality protein.
