Ingredients You’ll Need

Don’t be fooled by how straightforward the ingredient list is—each component is essential in crafting the perfect balance of creaminess, savory depth, and bright vegetable flavor that makes this dish shine.

Butter (3 tbsp, divided): Adds richness and helps sear the chicken to golden perfection.
Boneless, skinless chicken breast (2.5 lbs, sliced): The hearty protein base that soaks up every bit of the sauce.
Salt (½ tsp) and Black pepper (¼ tsp): Simple seasoning that brings out the natural flavors.
Chicken broth (2 tbsp): A small splash to smooth out the sauce and add savory depth.
Frozen broccoli (12 oz, steam bag): Convenient and perfectly vegetable-packed to add color and a tender bite.
Garlic cloves (3, minced): Infuses the sauce with an irresistible aroma and robust flavor.
Cream cheese (1 oz, softened): Gives the Alfredo sauce a velvety texture and tangy richness.
Heavy whipping cream (1 cup): The luxurious base that makes this bake decadently creamy.
Italian seasoning (½ tsp): A blend that brings herbal warmth and complexity.
Grated Parmesan cheese (⅔ cup): A salty, nutty punch that enriches the sauce.
Grated Pepper Jack cheese (¼ cup): Adds a subtle spicy kick and melts beautifully.
Grated Mozzarella cheese (¾ cup): The gooey topper that browns perfectly in the oven.
Dried basil (¼ tsp): A touch of fragrant herb sprinkled on top for freshness and color contrast.

How to Make Keto Chicken Alfredo with Broccoli Bake Recipe

Step 1: Prep Your Oven and Broccoli

Start by preheating your oven to 375°F (190°C) and lightly greasing a baking dish—this will prevent sticking and help the cheese develop that perfect golden crust. While the oven warms, steam your broccoli following the package instructions. Steaming keeps the broccoli tender yet crisp, which balances so well with the creamy sauce later.

Step 2: Sear the Chicken

In a large skillet, melt 2 tablespoons of butter over medium heat. Season your sliced chicken breasts with salt and black pepper, then sear them in the butter until they are beautifully browned on both sides and cooked through. This step locks in flavor and gives the chicken a lovely texture. Once done, remove the chicken from the pan and set aside.

Step 3: Build the Alfredo Sauce

Using the same skillet, melt the remaining tablespoon of butter and toss in the minced garlic. Cook until fragrant—this garlic-infused butter is going to be the base of a dreamy sauce. Next, stir in the softened cream cheese and chicken broth, mixing until the sauce is smooth and silky. Pour in the heavy whipping cream along with the Italian seasoning and let it simmer for 2 to 3 minutes to thicken slightly.

Step 4: Mix in the Cheeses

Now for the cheesy magic: stir in the grated Parmesan and Pepper Jack cheeses gradually until they melt into a velvety sauce. The combination of these cheeses gives the dish depth and just the right amount of kick, creating a sauce that clings perfectly to the chicken and broccoli.

Step 5: Assemble and Bake

Return the cooked chicken and steamed broccoli to the Alfredo sauce, gently folding everything together. Transfer this luscious mixture into your greased baking dish. Top with the grated Mozzarella and sprinkle a little dried basil over the surface to add a fresh, herbal note. Bake in your preheated oven for about 20 minutes, or until the sauce is bubbly and the cheese forms a golden, irresistible crust.

Step 6: Rest and Serve

Once your bake comes out of the oven, let it rest for 5 minutes. This brief pause ensures the sauce sets nicely for hearty serving without losing any of its creamy goodness.

How to Serve Keto Chicken Alfredo with Broccoli Bake Recipe

Garnishes

Sprinkling a little fresh chopped parsley or extra dried basil on top adds a lovely pop of color and a hint of herbal brightness that cuts through the richness. A grating of fresh Parmesan right before serving also elevates the dish’s cheesy appeal.

Side Dishes

Since this dish is a complete keto-friendly meal, simple sides like a crisp green salad dressed lightly with lemon vinaigrette or a handful of marinated olives complement it beautifully without overpowering. For something heartier, steamed asparagus or garlic sautéed spinach create a lovely low-carb vegetable duo.

Creative Ways to Present

For a fun twist, try serving individual portions in ramekins topped with a little extra mozzarella to get that golden crust in personal servings. You can also layer the bake in a casserole with alternating layers of broccoli and chicken for a pretty presentation before baking. It’s perfect for potlucks or family dinners when you want to impress without the fuss.

Make Ahead and Storage

Storing Leftovers

Any leftovers from your Keto Chicken Alfredo with Broccoli Bake Recipe store wonderfully in an airtight container in the refrigerator for up to 3 days. The flavors deepen overnight, making it perfect for next-day lunches or a quick dinner.

Freezing

If you want to save some for later, this bake freezes well before the final cheese topping is added. Freeze in a sealed container for up to 2 months. When you’re ready to enjoy, thaw overnight in the fridge, top with mozzarella and basil, and bake as directed.

Reheating

Reheat your leftovers gently in the oven at 350°F (175°C) until warmed through to keep the sauce creamy and the chicken tender. You can also microwave single servings on medium power, but be mindful not to overheat or the sauce could break and the chicken dry out.

FAQs

Can I use fresh broccoli instead of frozen?

Absolutely! Fresh broccoli works beautifully here—just steam it until tender crisp before adding it to the sauce. It may add a bit more vibrant color and a fresh crunch, which balances the creamy sauce nicely.

Is this recipe suitable for meal prep?

Yes, this Keto Chicken Alfredo with Broccoli Bake Recipe is perfect for meal prep. It reheats well and keeps its flavor and texture, making it an excellent choice for make-ahead lunches or dinners during a busy week.

What can I substitute for heavy cream?

If you don’t have heavy cream on hand, full-fat coconut milk can be used for a slightly different but still creamy keto-friendly sauce. Just be aware it will add a subtle coconut flavor, which pairs well with the seasonings in this dish.

Can I make this recipe dairy-free?

To make a dairy-free version, you’d need to swap out the butter, cream cheese, heavy cream, and cheeses for plant-based alternatives. While it will change the flavor profile slightly, using dairy-free cream cheese, coconut cream, and vegan cheeses can still yield a delicious bake.

How spicy is the dish with Pepper Jack cheese?

The amount of Pepper Jack cheese adds a mild spice and peppery flavor without overwhelming the creamy sauce. If you prefer it milder, you can reduce the quantity or substitute with a milder cheese like Monterey Jack.
