Let’s Talk About the Chicken
First things first, let’s get that chicken prepped! You want to use boneless, skinless chicken breasts for this Chicken Alfredo Broccoli Bake. Cutting them into bite-sized pieces ensures they cook quickly and evenly, plus it makes it easier to eat in the final dish. I like to toss the chicken with olive oil, garlic powder, salt, and pepper for a simple but flavorful seasoning. Don’t skimp on the garlic powder – it adds a really nice depth of flavor. This is an easy keto recipes chicken strategy, since you are only using the breast and eliminating the carbs from the skin.
Broccoli: Not Just a Side Dish!
Now, let’s talk broccoli. I know, I know, some people aren’t huge fans, but trust me, in this Chicken Alfredo Broccoli Bake, it’s amazing! Roasting the broccoli brings out its natural sweetness and gives it a slightly crispy texture that complements the creamy Alfredo sauce perfectly. Toss the broccoli florets with olive oil, salt, and pepper, and roast them in the oven until they’re tender-crisp. If you’re short on time, you can steam the broccoli instead, but I highly recommend roasting for the best flavor and texture. You can even customize this to your liking, like adding cauliflower, too! This recipe is great for Chicken Broccoli Alfredo Bake as well.
The Secret to the Perfect Alfredo Sauce
Okay, now for the star of the show: the Alfredo sauce! A good Alfredo sauce can make or break this Chicken Alfredo Broccoli Bake. The key is to use high-quality ingredients and take your time. Start by melting butter in a saucepan over medium heat. Add the minced garlic and cook until fragrant, but be careful not to burn it. Then, pour in the heavy cream and bring it to a simmer. Reduce the heat and let it simmer for a few minutes, allowing it to thicken slightly. Stir in the Parmesan cheese until it’s melted and smooth. Season with salt, pepper, and a pinch of nutmeg (if using). Taste and adjust the seasoning as needed. I find that using freshly grated Parmesan cheese makes a huge difference in the flavor and texture of the sauce. This can also be a great start to good keto recipes for dinner, as the sauce and chicken are already keto friendly.
