Ingredients

You don’t need anything complicated. Most of these are pantry staples, and if you don’t have Cajun seasoning, you can make your own with a few spices.

For the Cajun Chicken:

• 2 large chicken breasts (or 4 boneless, skinless thighs)
• 2 teaspoons Cajun seasoning (store-bought or homemade – recipe below)
• ½ teaspoon salt
• ½ teaspoon black pepper
• 1 teaspoon paprika
• ½ teaspoon garlic powder
• ½ teaspoon onion powder
• 1 tablespoon olive oil or butter for cooking

For the Broccoli Alfredo Sauce:

• 2 cups broccoli florets
• 2 tablespoons butter
• 3 cloves garlic, minced
• 1 ½ cups heavy cream
• 1 ½ cups shredded Parmesan cheese
• ½ teaspoon salt (adjust to taste)
• ½ teaspoon black pepper
• ½ teaspoon Cajun seasoning (optional for extra spice)

How to Make Keto Cajun Chicken Broccoli Alfredo

This recipe is straightforward—season, cook, make the sauce, and put it all together. Here’s the step-by-step breakdown.

Step 1: Prepare the Chicken

• Pat the chicken dry with a paper towel. This helps it get a nice sear.
• In a small bowl, mix together Cajun seasoning, salt, pepper, paprika, garlic powder, and onion powder.
• Rub the seasoning mixture all over the chicken. Make sure it’s evenly coated.
• Heat a large skillet over medium-high heat and add the olive oil (or butter).
• Place the chicken in the skillet and cook for about 5-6 minutes per side, depending on thickness. You want a golden-brown crust.
• Check for doneness using a meat thermometer—internal temperature should be 165°F (75°C).
• Once done, transfer to a plate and let it rest for 5 minutes before slicing.

Step 2: Cook the Broccoli

• Bring a pot of salted water to a boil.
• Add the broccoli florets and blanch them for about 2-3 minutes until they turn bright green.
• Drain and set aside. If you prefer softer broccoli, steam it for a couple more minutes.

Step 3: Make the Alfredo Sauce

• In the same skillet where you cooked the chicken, melt 2 tablespoons of butter over medium heat.
• Add the minced garlic and cook for about 30 seconds until fragrant.
• Pour in the heavy cream and bring to a gentle simmer.
• Stir in the Parmesan cheese, salt, pepper, and Cajun seasoning. Keep stirring until the cheese melts and the sauce thickens. This should take about 3-5 minutes.
• Add the cooked broccoli to the sauce and stir to coat it evenly.

Step 4: Put It All Together

• Slice the rested chicken into thin strips.
• Add the chicken back into the skillet with the Alfredo sauce and broccoli.
• Stir everything together, letting the flavors meld for 1-2 minutes.
• Taste and adjust seasoning if needed. If the sauce is too thick, add a splash of heavy cream.

Tips for the Best Keto Cajun Chicken Broccoli Alfredo

 

• Use fresh Parmesan cheese – Pre-shredded cheese has anti-caking agents that can make the sauce grainy.
• Don’t overcook the chicken – Dry chicken is no fun. Use a thermometer if you’re unsure.
• Adjust the spice level – If you want more heat, add extra Cajun seasoning or a pinch of cayenne pepper.
• Make it extra creamy – Add a bit of cream cheese to the Alfredo sauce for a thicker, richer texture.
• Meal prep friendly – Store leftovers in an airtight container in the fridge for up to 4 days.

Serving Ideas

• Serve as is for a low-carb meal.
• Pair with zucchini noodles or cauliflower rice if you want a pasta-like experience.
• Add a side of garlic butter mushrooms for extra flavor.

How to Store and Reheat

This dish keeps well, making it perfect for meal prep.

To Store:

• Keep in an airtight container in the fridge for up to 4 days.
• Freeze portions in a sealed container for up to 2 months.

To Reheat:

• Warm in a skillet over low heat with a splash of heavy cream to bring the sauce back to life.
• Microwave in 30-second bursts, stirring between each, to avoid overheating the sauce.

Homemade Cajun Seasoning (If You Don’t Have Store-Bought)

If you want to make your own Cajun seasoning, mix the following:

• 1 tablespoon paprika
• 1 teaspoon salt
• 1 teaspoon black pepper
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• ½ teaspoon cayenne pepper (adjust for heat)
• ½ teaspoon thyme
• ½ teaspoon oregano

Mix and store in a jar—it’s great on chicken, shrimp, and even roasted veggies.

Conclusion

Keto doesn’t mean boring, and this Cajun Chicken Broccoli Alfredo proves it. With juicy, spiced chicken, a creamy cheese sauce, and fresh broccoli, every bite is packed with flavor.

It’s a quick, satisfying meal that works for weeknights, meal prep, or even a fancy low-carb dinner. Give it a try—you won’t miss the pasta one bit.
