1 – Choosing the Right Chicken
Your chicken choice affects texture, flavor, and nutritional balance.
Boneless Skinless Breasts
Lean, high in protein, and low in fat—ideal if you’re closely tracking calories as well as carbs. They hold shape well when baked.
Boneless Skinless Thighs
Richer flavor, more tender, and naturally higher in fat—perfect for keto macros. They stay moist even if slightly overbaked.
Time-Saving Option
Use pre-cooked chicken from a rotisserie or leftovers from another meal. Shred it and you’re halfway to dinner.
Pro Tip: Season chicken generously before cooking for best flavor integration.
2 – The Best Broccoli for Baking
Broccoli keeps the dish fresh and adds nutrient density.
Fresh Broccoli
Cut into small florets for even cooking. Steam or blanch briefly before adding to the casserole to ensure tender results.
Frozen Broccoli
A convenient choice, but thaw and drain thoroughly to avoid excess water in your bake.
Broccoli doesn’t just bring vitamins and fiber—it also adds texture contrast to the creamy sauce and cheese.
3 – Keto-Friendly Alfredo Sauce
At the heart of this dish is the Alfredo sauce, and keeping it keto means skipping flour-based thickeners.
