Instructions to Make Creamy Keto Chicken Alfredo Broccoli Bake

Ready to dive into dinner? Follow this step-by-step guide to make your Creamy Keto Chicken Alfredo Broccoli Bake with ease. Whether you’re a seasoned cook or new to the low-carb life, these instructions break everything down so you can prep, cook, and serve this cozy casserole without a hitch. We’ve even included handy links for extra tips and tricks along the way.

Step 1: Preheat Your Oven and Gather Your Tools

First things first—preheat your oven to 350°F (175°C). This gives it plenty of time to get to the right temperature while you assemble your ingredients. A properly preheated oven is the key to a golden, bubbly top and evenly cooked casserole.

You’ll also need:

• A large mixing bowl (preferably one that gives you elbow room to stir)
• A greased baking dish (8×8 or similar size works well)
• A spoon or spatula for stirring
• An oven mitt (because cheese burns are no joke)

Step 2: Prep the Chicken and Broccoli

In your mixing bowl, add 2 cups of shredded, cooked chicken. If you’re using leftovers or rotisserie chicken, make sure it’s shredded into bite-sized pieces for even flavor distribution. You want every forkful to have a bit of chicken in it.

Now, stir in 2 cups of steamed broccoli. The broccoli should be just tender—not mushy. If you’re using frozen broccoli, thaw and pat it dry to avoid excess moisture that can water down your sauce.

Step 3: Make the Creamy Alfredo Sauce

This step is where the magic happens. Pour in 1 cup of heavy cream, followed by 1 cup of shredded mozzarella cheese (or swap in cheddar or Gouda if you want to mix things up). Then, add 1 teaspoon of garlic powder, or use freshly minced garlic for a bolder flavor.

Season generously with salt and pepper to taste. Stir everything together until the chicken and broccoli are fully coated in that creamy, cheesy goodness.

Want to add some kick? Try tossing in a pinch of red pepper flakes or a dash of Italian seasoning. For more ideas, check out our list of low-carb ingredient swaps and upgrades.

Step 4: Transfer to Baking Dish

Once everything is mixed and mingling, pour the mixture into your greased baking dish. Use a spoon or spatula to spread it out evenly, but don’t press it down too hard. You want the cheese and cream to bubble through the layers.

This step-by-step layering helps the casserole bake evenly and ensures every bite gets a taste of that dreamy Alfredo sauce.

Step 5: Bake to Golden Perfection

Slide your dish into the preheated oven and bake for 25–30 minutes. You’ll know it’s done when the top is golden brown and the edges are bubbling like a hot tub for cheese lovers.

If you’re a fan of crispy toppings, consider sprinkling Parmesan cheese or crushed pork rinds on top before baking for extra texture and flavor. Need more crispy, cheesy recipes? Don’t miss our Parmesan Crusted Chicken Sheet Pan Dinner—it’s another keto-friendly hit.

Step 6: Let It Cool Before Serving

Now, here’s a step that’s easy to skip but totally worth it: let the bake rest for 5 minutes after it comes out of the oven. This short wait time helps the sauce thicken slightly and makes the casserole easier to serve.

Plus, you won’t risk burning your mouth on molten cheese (we’ve all been there). Use this time to throw together a quick side salad or set the table.

What to Serve with Creamy Keto Chicken Alfredo Broccoli Bake

This dish is filling on its own, but a little something on the side never hurt. Keep it low-carb with a side salad, tossed with olive oil and lemon, or maybe some roasted cauliflower for extra veggie power. If you’ve got non-keto family at the table, serve it with some crusty garlic bread or rice to round things out. And for drinks? A crisp white wine or sparkling water with lime fits perfectly. Oh—and if you’re feeling extra cozy? Try it with a bowl of Lemon Chicken Orzo Soup to start.

Key Tips for Making Creamy Keto Chicken Alfredo Broccoli Bake

Want to nail this recipe the first time? Here’s what you need to know. Use pre-cooked chicken (rotisserie is your friend) to cut prep time. Don’t over-steam the broccoli—just enough to soften it slightly. You want it to hold up in the bake. Choose your cheese wisely—mozzarella gives a mild, melty texture, but cheddar adds a stronger flavor. Feeling fancy? Add a sprinkle of Parmesan on top before baking for a golden crust. And don’t skip the rest time after baking—five minutes helps the sauce thicken and flavors blend. Got picky eaters? Add a little cooked bacon or sautéed mushrooms to customize it. This recipe is forgiving and flexible—just like your favorite pair of stretchy pants.

Storage and Reheating Tips for Creamy Keto Chicken Alfredo Broccoli Bake

Leftovers? Lucky you. This bake stores like a champ. Let it cool completely, then cover and refrigerate for up to 4 days. Want to freeze it? You bet—just portion it into airtight containers and freeze for up to 3 months. To reheat, microwave individual portions in 30-second bursts, stirring in between, until hot. Or warm it in a 325°F oven for about 15–20 minutes, covered with foil. If the sauce seems too thick, add a splash of cream or chicken broth while reheating to bring it back to life. Honestly, this dish might even taste better the next day—cheesy casseroles have a magical way of getting cozier with time.
