Tips for Perfect Keto Chicken Alfredo Casserole

1. Use Freshly Grated Parmesan : Pre-grated cheese often contains anti-caking agents that can affect the creaminess of the sauce. Grate your own for the best results.
2. Don’t Overcook the Zoodles : If using zucchini noodles, avoid overcooking them to prevent them from becoming mushy. Sauté them lightly before assembling the casserole if desired.
3. Experiment with Cheeses : Try using smoked Gouda, fontina, or asiago for a deeper, more complex flavor.
4. Store Properly : Keep leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven to maintain texture.
