Ingredients You’ll Need
Making this Keto Chicken Alfredo Bake is easier than you think. Here’s what you’ll need to gather before getting started:
- Chicken Breasts: Boneless, skinless chicken breasts cut into bite-sized chunks.
- Italian Seasoning: Brings that fragrant herb flavor.
- Garlic Powder: A must for rich, garlicky notes.
- Salt and Pepper: To season the chicken perfectly.
- Olive Oil: For searing the chicken; you can substitute avocado oil or coconut oil if preferred.
- Keto Alfredo Sauce: You can use homemade (made with cream cheese, Parmesan, and butter) or your favorite store-bought brand.
- Broccoli Florets: Fresh or frozen works fine; lightly steam them before layering.
- Mozzarella Cheese: Shredded mozzarella makes the perfect gooey, golden topping. You can also use an Italian blend or mild cheddar.
💡 Tip: Steaming the broccoli for just 2 minutes keeps it bright green and slightly crisp, so it doesn’t get soggy when baked.
How to Make Keto Chicken Alfredo Bake with Broccoli
Step 1: Prepare the Chicken
In a large bowl, toss your chicken pieces with Italian seasoning, garlic powder, salt, and black pepper. Heat olive oil in a skillet over medium heat and sear the chicken until golden brown—about 3–4 minutes per side. Set aside once cooked through.
Step 2: Layer the Casserole
Spread a thin layer of Alfredo sauce on the bottom of your baking dish (9×13 works best).
Next, layer half of the chicken and broccoli over the sauce. Pour half of the remaining Alfredo sauce evenly on top, then sprinkle a layer of shredded mozzarella.
Repeat with the remaining chicken, broccoli, sauce, and cheese.
Step 3: Bake and Broil
Bake the casserole until the cheese is melted and bubbly. For extra golden brown edges, broil for 2–4 minutes at low heat.
Once done, remove from the oven and garnish with freshly chopped parsley before serving.
Tips and FAQs
Can I use jarred Alfredo sauce?
Absolutely! If you’re short on time, store-bought Alfredo sauce works great. Look for low-carb versions with no added sugar. Homemade sauce will have a richer flavor, but jarred sauce keeps things quick and easy.
Can I make this with leftover chicken?
Yes! You can use pre-cooked chicken, such as shredded rotisserie or grilled leftovers. This saves time and adds even more flavor to your dish.
What other vegetables can I add?
Feel free to sneak in extra veggies like spinach, zucchini noodles, cauliflower, or even spaghetti squash. They all pair perfectly with the creamy Alfredo base and keep the dish low-carb.
Can I make this ahead of time?
Definitely. You can assemble the casserole a day in advance, cover it, and refrigerate it. When ready to eat, bake until hot and bubbly.
How to Store and Reheat
Store any leftovers in an airtight container in the refrigerator for up to 4 days.
To reheat, place a portion in the microwave for 1–2 minutes or rewarm the entire casserole in the oven at 350°F (175°C) for 10–15 minutes.
