Low-Carb Chicken Alfredo Ingredients

Chicken breast – Cook fresh chicken yourself or use a rotisserie chicken from the store. This recipe is a great opportunity to use shredded meal prep chicken or any leftover bits you have on hand.

Seasoning – A generous portion of garlic powder, plus salt and pepper, is all you need for mouthfuls of flavor.

Butter – Only needed if you are cooking chicken. Precooked chicken only needs to be chopped or shredded into smaller pieces before getting layered with broccoli and sauce.

Broccoli – The vegetable of choice in this one-dish casserole meal. You can steam it fresh or use meal prep precooked broccoli. Four cups of trimmed broccoli florets equals about 2 pounds of fresh, untrimmed broccoli or roughly 16 ounces of frozen chopped broccoli. [1] So you can buy fresh broccoli or use a bag of frozen broccoli.

Alfredo sauce – Full of healthy fats, this rich and creamy sauce layers between the ingredients and permeates every bite. I’ll share a recipe with you here, but you can use store-bought sauce if you prefer.

Homemade Alfredo sauce ingredients include:

  • Butter
  • Garlic
  • Heavy cream
  • Parmesan
  • Ground nutmeg 

Mozzarella cheese – One of the best choices for melting, the long strings of melted cheese make this a family-favorite recipe.

Parsley – For a touch of color and nice flavor

Step-By-Step Directions

Follow these simple directions, and you can’t go wrong!

Cook the chicken, steam the broccoli and then layer with alfredo sauce in a casserole dish. Cover it all with shredded cheese and bake until the cheese melts!

The process is even faster if you meal prep the chicken and broccoli ahead of time. 

Step one: Cook chicken

Start by cutting the chicken breast into ½-inch cubes. Then, toss it in a bowl with garlic powder, salt, and pepper. Coat all sides evenly with the seasoning. 

Heat the butter in a skillet over medium-high heat and pan-fry the chicken for approximately 3 minutes on each side. Once cooked through, remove from heat and set aside. 

Laura Fuentes has a great step-by-step tutorial on how to cook chicken pieces in a pan. If this is a new method for you, I suggest reviewing the directions first. It’s very easy, but the visuals can be helpful.

Step two: Steam broccoli

While the chicken cooks, begin trimming the broccoli and cut it into florets (just the top part, with minimal stalk). Steam broccoli until tender for about 6 minutes. Remove from heat and set aside.

Step three: Make Alfredo sauce

While the broccoli steams, begin preparing the Alfredo sauce. If you are using store-bought sauce, jump down to the next step.

Simmer the garlic in butter in a small saucepan for two minutes until fragrant. Mix in cream. Slowly add the parmesan and stir continuously until it’s a thick, uniform sauce. Finally, season with nutmeg, remove from heat and set aside.

Step four: Assemble and bake

Put the chicken bake together by spreading ½ cup of Alfredo sauce in the bottom of a 9×13-inch baking dish. Layer half the cooked chicken with half of the steamed broccoli arranged over it.

Then, spoon 1 cup of Alfredo sauce over the broccoli and sprinkle 1 cup of mozzarella cheese on top of the sauce.

Per 1 cup of chicken Alfredo with pasta noodles, there is a whopping 56 g total carbohydrate with 2.5 g fiber. That’s 53.5 g net carb in just a cup.

    I love being able to put everything in one casserole dish and not having to prep sides separately. While beef is still my favorite, this is a chicken dish totally worth making.
