Ingredients

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

Fettuccine pasta provides the classic base for this dish, though you can substitute any pasta shape you prefer. The long, flat noodles are particularly good at holding onto the creamy sauce.

Chicken breast offers lean protein that makes this dish satisfying and substantial. It's mild flavor pairs perfectly with the alfredo sauce.

Broccoli florets add vibrant color, fiber, and nutrients to balance the richness of the dish. They absorb the sauce beautifully and provide a pleasant textural contrast.

Cauliflower forms the secret base of our lightened-up alfredo sauce, creating creaminess without heavy cream. When cooked and blended, it develops a surprisingly smooth texture.

Parmesan cheese brings that essential salty, umami flavor that defines a true alfredo sauce. Even in smaller quantities, it delivers big impact.

Garlic infuses the sauce with aromatic depth and complements both the chicken and vegetables perfectly.

Low-sodium chicken broth helps create the sauce while adding flavor without excess sodium.

Milk adds creaminess to the sauce while keeping it lighter than traditional cream-based versions.

Olive oil is used for sautéing, providing heart-healthy fats in place of butter.

Salt and pepper are simple but crucial seasonings that enhance all the flavors in the dish.

Red pepper flakes add an optional touch of heat that balances the richness of the sauce.

Directions

Bring a large pot of salted water to a boil. Add fettuccine and cook according to package directions until al dente. In the last 3 minutes of cooking, add the broccoli florets to the pasta water. Drain pasta and broccoli, reserving 1 cup of pasta water.
While the pasta cooks, prepare the cauliflower alfredo sauce. In a separate pot, combine the cauliflower florets and chicken broth. Bring to a boil, then reduce heat and simmer for 8-10 minutes until the cauliflower is very tender.
Heat olive oil in a large skillet over medium-high heat. Season chicken pieces with salt and pepper, then add to the skillet. Cook for 5-6 minutes until golden and cooked through. Remove chicken and set aside.
In the same skillet, add minced garlic and sauté for 30 seconds until fragrant.
Transfer the cooked cauliflower (but not the broth) to a blender. Add ½ cup of the cooking broth, milk, Parmesan cheese, garlic, salt, and pepper. Blend until completely smooth and creamy.
Return the blended sauce to the skillet and heat on low. If sauce is too thick, add some of the reserved pasta water until desired consistency is reached.
Add the cooked pasta, broccoli, and chicken to the skillet with the sauce. Gently toss everything together until well coated. If needed, add more reserved pasta water to thin the sauce.
Garnish with additional Parmesan cheese and red pepper flakes if desired. Serve immediately.

Servings and Timing

This recipe yields 4 generous servings. Preparation takes approximately 15 minutes, and cooking time is about 25 minutes, for a total time of 40 minutes. It's perfect for a weeknight dinner but impressive enough for company. Each serving contains approximately 350-400 calories, making it significantly lighter than traditional chicken alfredo which can run 800-1000 calories per serving.

Variations

Vegetarian Version: Skip the chicken and add more vegetables like mushrooms, spinach, or bell peppers for a meat-free alternative.

Seafood Alfredo: Replace chicken with shrimp or scallops for an elegant seafood variation.

Gluten-Free Option: Use your favorite gluten-free pasta instead of traditional fettuccine.

Extra Veggie Boost: Add zucchini, yellow squash, or cherry tomatoes for additional color and nutrition.

Whole Grain Upgrade: Substitute whole wheat pasta for additional fiber and nutrients.

Dairy-Free Alternative: Use unsweetened almond milk and nutritional yeast instead of dairy milk and Parmesan for a vegan-friendly option.

Spicy Kick: Increase the red pepper flakes or add a dash of hot sauce for those who enjoy more heat.

Herb Enhancement: Add fresh herbs like basil, parsley, or thyme to brighten the flavors.

Storage/Reheating

This lightened-up Chicken Broccoli Alfredo stores well, making it perfect for meal prep. Allow leftover pasta to cool completely before transferring to airtight containers. Refrigerate for up to 3-4 days.

When reheating, add a splash of milk or chicken broth to revive the sauce, as it will thicken when cold. Gently warm on the stovetop over medium-low heat, stirring frequently to prevent sticking and help the sauce return to its creamy consistency.

For quicker reheating, microwave individual portions at 50% power for 1-2 minutes, stirring halfway through. The reduced power helps prevent the sauce from separating.

This dish is not ideal for freezing as the creamy sauce may separate upon thawing and the pasta texture can become mushy. For best results, enjoy refrigerated leftovers within a few days of preparation.

FAQs

Why use cauliflower in an alfredo sauce?

Cauliflower creates a surprisingly creamy texture when cooked and blended, while containing significantly fewer calories and less fat than heavy cream. It's also a great way to incorporate more vegetables into your meal without sacrificing the indulgent feel of alfredo sauce.

Can I make this recipe ahead of time?

Yes, you can prepare the components ahead of time. Make the cauliflower sauce up to 2 days in advance and store in the refrigerator. Cook the pasta and broccoli just before serving, as pasta tends to absorb sauce and can become mushy if left too long.

What's the best way to reheat leftovers without the sauce separating?

Reheat gently over low heat on the stovetop, adding a splash of milk to revive the creaminess. Stir frequently to prevent sticking and to help redistribute the sauce evenly.

Can I use frozen broccoli instead of fresh?

Absolutely! Frozen broccoli works well in this recipe. No need to add it to the pasta water; simply thaw and drain it, then add it to the sauce when combining all ingredients.

Is there a dairy-free version of this recipe?

Yes, you can make this dairy-free by using unsweetened almond milk instead of regular milk and substituting nutritional yeast for the Parmesan cheese. The cauliflower base already helps create creaminess without relying entirely on dairy.

What can I substitute for fettuccine pasta?

Any pasta shape works well with this sauce. Try penne, rotini, or bowties for a different texture. For a lower-carb option, use zucchini noodles or spaghetti squash.

How can I make this recipe even higher in protein?

To increase the protein content, you can add more chicken, mix in some Italian turkey sausage, or even stir in a handful of white beans for a vegetarian protein boost.

Will my kids eat a cauliflower-based sauce?

Most kids won't detect the cauliflower when it's properly cooked and blended into a smooth sauce. The Parmesan cheese and garlic give it a familiar alfredo flavor that appeals to young palates.

Can I add other vegetables to this dish?

Definitely! This recipe is very adaptable. Try adding spinach, peas, mushrooms, bell peppers, or asparagus for additional nutrition and flavor variety.

How do I prevent the sauce from being too watery?

Make sure to thoroughly drain the cauliflower before blending, using only the amount of cooking liquid called for in the recipe. If your sauce seems too thin, simmer it for a few extra minutes to reduce and thicken before adding the pasta.
