Ingredients You’ll Need

One of the best things about this Keto Chicken Alfredo with Broccoli Bake is how it relies on a handful of familiar, well-loved ingredients. Each one plays a crucial role, building savory depth, texture, and a pop of color to every bite.
Ready for the rundown?

Butter (3 tbsp, divided): Gives the sauce a rich foundation and helps brown the chicken for extra flavor.
Boneless skinless chicken breast (2.5 lbs, sliced): The main event, providing juicy protein to anchor the bake.
Salt (1/2 tsp): Simple but essential for seasoning every layer just right.
Pepper (1/4 tsp): Adds a gentle, peppery kick.
Chicken broth (2 tbsp): Helps deglaze the pan, pulling up all those tasty browned bits.
Frozen broccoli (12 oz steam bag): Brings color, crunch, and nutritious green freshness.
Garlic cloves (3, minced): The aromatic backbone—don’t skip these!
Cream cheese (1 oz, softened): Adds luxurious thickness to the Alfredo sauce.
Heavy whipping cream (1 cup): Makes the sauce silky and decadent while keeping carbs low.
Italian seasoning (1/2 tsp): Layers in those friendly, herby notes everyone loves in Alfredo.
Parmesan cheese (2/3 cup, grated): The classic, nutty punch that defines Alfredo!
Pepper jack cheese (1/4 cup, grated): A subtle hint of heat and meltiness.
Mozzarella cheese (3/4 cup, grated): For that irresistible, stretchy top layer.
Basil (1/4 tsp): The final herbal flourish—just a dusting, but it goes a long way.

How to Make Keto Chicken Alfredo with Broccoli Bake

Step 1: Sear and Cook the Chicken

Begin by melting 1 tablespoon of butter in a large, oven-safe skillet. Season your sliced chicken breasts with salt and pepper, then add them to the skillet. Let each side sear for a few minutes—you’re looking for a golden color, not just to cook the chicken through, but to build layers of flavor. Once both sides are just about browned, pop a lid on and let the chicken simmer on low heat until there’s not a hint of pink left.

Step 2: Remove Chicken and Deglaze

Set the chicken aside for now, and don’t wipe out that skillet! Pour in the chicken broth and grab a wooden spoon to scrape up all the browned bits stuck to the bottom. These morsels are loaded with flavor and will work their magic in the sauce. Leave them right in the pan for extra savoriness.

Step 3: Steam the Broccoli

While flavor builds in the skillet, steam the broccoli according to the package directions right in the microwave. Prefer a stovetop method? Boil some water and steam the florets until just tender with a slight crunch; overcooked broccoli will lose its vibrant color and texture in the final bake.

Step 4: Sauté Garlic and Start the Sauce

Pop the remaining 2 tablespoons of butter into the skillet, followed by the minced garlic. Sauté for about 2 minutes until your kitchen smells amazing and the garlic is fragrant—you want it softened but not burnt. Now, stir in the softened cream cheese, heavy cream, and Italian seasoning. Keep things moving with a whisk so you end up with a smooth, dreamy sauce.

Step 5: Thicken and Enrich the Alfredo Sauce

Lower the heat a notch and keep whisking while your sauce gently bubbles and reduces. This thickening step is key to a luscious, clingy sauce (no watery Alfredo here!). Once it’s thickened to your liking, stir in the grated parmesan and pepper jack cheese. Watch as everything melts together into a silken sauce that smells like pure comfort food.

Step 6: Add Chicken and Broccoli Back

Drain your steamed broccoli and bring both the chicken and broccoli back into the skillet, nestling them right into all that creamy sauce. Stir gently to ensure every piece is coated so the flavors meld together harmoniously in the Keto Chicken Alfredo with Broccoli Bake.

Step 7: Top and Broil

Scatter the grated mozzarella cheese evenly over the top, then give everything a loving sprinkle of dried basil. Slide your skillet onto the oven’s top rack under the broiler for 1 to 2 minutes. Don’t wander off! You want the cheese to bubble and brown a bit but not burn. This finishing touch gives you that irresistible, gooey golden crust that sets the Keto Chicken Alfredo with Broccoli Bake apart.

How to Serve Keto Chicken Alfredo with Broccoli Bake

Garnishes

Freshly chopped parsley or a few extra grates of parmesan deliver a bright finishing touch. A crack of black pepper or a sprinkle of red pepper flakes also wakes up the flavors, making every serving of Keto Chicken Alfredo with Broccoli Bake look and taste restaurant-worthy.

Side Dishes

This bake is rich and filling on its own, but a simple side salad—think crisp romaine or mixed baby greens with a tangy vinaigrette—adds a lovely, lighter contrast. For real Italian vibes while keeping things keto, try a side of roasted asparagus or sautéed zucchini ribbons alongside your Keto Chicken Alfredo with Broccoli Bake.

Creative Ways to Present

Spoon it into small ramekins for dinner party-ready individual servings, or pile it into a big platter for family-style sharing. For a fun twist, let the cheese topping brown up extra and use a spatula to cut “squares” for a brunch-style casserole effect. However you present it, Keto Chicken Alfredo with Broccoli Bake is a total crowd-pleaser!

Make Ahead and Storage

Storing Leftovers

Any leftovers (if you have them!) can be cooled to room temperature and stored in an airtight container in the refrigerator for up to four days. The flavors actually deepen overnight, so the Keto Chicken Alfredo with Broccoli Bake is just as delicious, if not better, the next day.

Freezing

You can freeze this recipe for up to two months. Let it cool completely before packing it into a freezer-safe dish or container. To prevent freezer burn, make sure it’s tightly wrapped. Thaw overnight in the fridge before reheating for best results.

Reheating

Gently reheat leftovers in the oven (covered at 350°F until hot) or in the microwave. You might want to add a splash of cream or a sprinkle of cheese before reheating to revive that creamy, gooey texture that makes Keto Chicken Alfredo with Broccoli Bake irresistible.

FAQs

Can I use chicken thighs instead of chicken breasts?

Absolutely! Chicken thighs are flavorful and juicy, and make a great swap in Keto Chicken Alfredo with Broccoli Bake. You might need to trim a bit of fat, but otherwise, follow the recipe as written for equally delicious results.

Is it necessary to use an oven-safe skillet?

While using an oven-safe skillet (like cast iron) makes it easy to move from stovetop to broiler, you can also transfer everything to a baking dish just before sprinkling the mozzarella and broiling. It’s one extra dish to wash, but the results will still be awesome.

Can I add other vegetables?

Totally! Feel free to toss in sautéed mushrooms, spinach, or even cauliflower florets. This recipe is flexible, so long as you choose low-carb, keto-friendly veggies to keep your Keto Chicken Alfredo with Broccoli Bake on point.

Is this recipe spicy with the pepper jack cheese?

The pepper jack adds the mildest hint of heat, but nothing overwhelming. If you want an extra kick, add a pinch of red pepper flakes. Otherwise, sub in more mozzarella or even fontina if you prefer no heat at all.

Can I make Keto Chicken Alfredo with Broccoli Bake ahead of time?

You sure can! Assemble everything up to the broiling step, cover, and stash in the fridge. When you’re ready, just broil until bubbly and golden. Perfect for meal prep or party planning.
