Why You’ll Love This Keto Chicken Broccoli Alfredo Bake

If you’ve been craving something creamy but worry about carbs creeping in, this recipe is a little kitchen win. It’s a comforting, weeknight-friendly dish that checks several boxes:

Low in carbs yet high in flavor, thanks to heavy cream, cream cheese, and a generous helping of parmesan.
One-pan-friendly prep with an easy bake that creates a rich, cheesy topping that everyone loves.
Make-ahead friendly: you can prep the components earlier in the day and bake when you’re ready.
Protein-packed and veggie-forward, so you feel satisfied without feeling heavy.

In addition to being delicious, this dish is forgiving. If you’re missing an ingredient, you can swap in another green—cauliflower florets work nicely, or you can use sliced mushrooms for a different texture. If you don’t have cream cheese, a bit more heavy cream and a splash of cream cheese substitute can do the trick. The beauty of a bake like this is that it’s resilient and friendly to substitutions while staying delicious.

Ingredients for Keto Chicken Broccoli Alfredo Bake

2 cups cooked chicken, shredded — the star protein that gives the bake substance and fullness.
2 cups broccoli florets — adds crunch and a pop of color; keeps the dish feeling light and veggie-forward.
1 cup heavy cream — the base of the creamy Alfredo sauce; rich and smooth.
8 oz cream cheese, softened — thickens the sauce and gives that classic Alfredo texture.
1 cup parmesan cheese, grated — sharp, salty flavor that drives the sauce forward.
1 cup mozzarella cheese, shredded — melts into a bubbly, golden crust on top.
2 cloves garlic, minced — a quick aromatics boost that rounds out the richness.
1 teaspoon Italian seasoning — a gentle herb lift that unifies the flavors.
Salt and pepper — to taste; adjust after tasting the sauce for balance.
1/4 cup chicken broth (optional) — can thin the sauce if you prefer a lighter texture.

Step-by-Step Guide to Making Keto Chicken Broccoli Alfredo Bake

Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish and set it aside for later.
Blanch or lightly steam the broccoli until just tender and bright green. Drain well and pat dry to remove excess moisture; this helps avoid a watery bake.
In a large skillet over medium heat, sauté the minced garlic in a little olive oil for about 1 minute until it’s fragrant but not browned. Add the shredded chicken to warm through, giving it a quick toss.
In a separate saucepan, whisk together the heavy cream, softened cream cheese, and grated Parmesan cheese over medium heat until smooth and creamy. If the mixture thickens too much, gradually whisk in a bit of chicken broth to reach a pourable consistency.
Stir in the Italian seasoning, then season with salt and pepper to taste. Fold in the broccoli and warm chicken mixture, ensuring everything is coated with the creamy sauce.
Pour the sauce and filling into the prepared baking dish. Evenly sprinkle the shredded mozzarella over the top to create a glossy, bubbly crust as it bakes.
Bake for 15–20 minutes, or until the cheese on top is melted, the edges are bubbling, and the top takes on a light golden color.
Remove the bake from the oven and let it rest for about 5 minutes. This short cooling period helps the sauce thicken a touch, making it scoopable and easy to serve.

Timing & Preparation Details

Active prep time: about 15 minutes.
Cook time: 25 minutes (including bake time and sauce simmer time).
Chill or rest time: optional 5 minutes after baking to set the sauce and make serving easier.
Make-ahead tip: you can prepare the sauce and the broccoli in advance, refrigerate, and assemble just before baking for an even quicker weeknight meal.
When is it ready to enjoy? It’s ready as soon as you see bubbling edges and a golden top. A quick rest makes serving tidier and the flavors meld beautifully.

Frequently Asked Questions

Can I use shredded rotisserie chicken for this recipe?

Absolutely. Rotisserie chicken is a convenient option that saves time. Just make sure it’s fully reheated and patted dry so the bake isn’t watery.

What can I substitute if I don’t have cream cheese?

You can use extra heavy cream with a tablespoon of butter to mimic the richness, or a dairy-free cream cheese substitute if needed. The sauce should still thicken nicely with parmesan and a little extra time on the stove.

How do I store leftovers and reheat them?

Store leftovers in an airtight container in the refrigerator for up to 3–4 days. Reheat in a microwave or oven until warmed through. If the sauce thickens during storage, whisk in a splash of milk or broth to loosen it up.
