Ingredients You’ll Need

• Boneless Skinless Chicken Thighs – Juicy and flavorful, perfect for soaking up the seasoning.

• Cajun Seasoning – Brings heat, boldness, and a distinctly Southern flavor.

• Olive Oil – Used to sauté the meats.

• Butter – Adds richness to the sauce and vegetables.

• Onion, Celery, Red Bell Pepper – The classic Cajun trinity for flavor foundation.

• Minced Garlic – A must for deep, aromatic flavor.

• Heavy Whipping Cream – Forms the base of the Alfredo sauce.

• Parmesan Cheese – Melts into the cream for a velvety, cheesy finish.

• Cauliflower Rice – A keto-friendly rice alternative that absorbs the flavors perfectly.

Kitchen Equipment You’ll Need

To make this recipe smooth and stress-free, gather the following kitchen tools:

• Large nonstick or cast-iron skillet

• Knife and cutting board

• Wooden spoon or heat-safe spatula

• Measuring spoons and cups

• Cheese grater (if shredding Parmesan from a block)

• Mixing bowl (optional, for prepping meat or vegetables)

Step-by-Step Instructions

1. Cook the Chicken

Heat olive oil in your skillet over medium-high heat. Season the chicken thighs with half of your Cajun seasoning. Add to the skillet and sauté until fully cooked—golden on the outside, juicy on the inside. Remove and set aside.

2. Brown the Sausage

Add sliced Andouille sausage to the same skillet and sauté until browned and heated through. This step adds flavor and texture. Remove and set aside with the chicken.

3. Sauté the Vegetables

Drain any excess oil from the skillet. Reduce heat to medium. Melt the butter, then add the onion, red bell pepper, and celery. Cook until softened—about 5–7 minutes. Stir in the garlic and cook for another 30 seconds until fragrant.

4. Make the Creamy Alfredo Sauce

Pour in the heavy cream and simmer, stirring occasionally, until the sauce begins to thicken. Add the Parmesan cheese and remaining Cajun seasoning. Stir until melted and combined.

5. Bring It All Together

Return the cooked chicken and sausage to the skillet. Mix in the cauliflower rice, and simmer everything together for another 5 minutes, allowing the flavors to meld and the rice to absorb the sauce.

6. Garnish and Serve

Top with chopped green onions and serve hot!

Helpful Tips for Best Results

• Cut meat and veggies into uniform sizes for even cooking.

• Use a good-quality Cajun seasoning or make your own to control salt and spice.

• Don’t overcook the cream sauce—keep it at a gentle simmer to avoid curdling.

• Fresh Parmesan melts better and gives a smoother finish than pre-grated varieties.

• Cauliflower rice can be fresh or frozen. If frozen, thaw and squeeze out excess moisture first.

Easy Variations & Swaps

One of the great things about this recipe is its flexibility. Try these variations to customize it:

• Make it dairy-free: Use coconut cream and nutritional yeast instead of cream and cheese.

• Swap chicken thighs for breasts if you prefer a leaner cut.

• Add mushrooms or spinach for extra veggies.

• Try a different sausage: Chorizo, kielbasa, or smoked turkey sausage can also work.

• Use zucchini noodles or shirataki noodles instead of cauliflower rice for a faux-pasta twist.

What to Serve with Cajun Alfredo

This meal is hearty on its own, but you can pair it with:

• Keto Garlic Bread (made with almond or coconut flour)

• Avocado slices or guacamole to cool the heat

• A crisp side salad with lemon vinaigrette

• Roasted asparagus or green beans

Drink Pairings:

• A glass of dry white wine (like Sauvignon Blanc)

• Sparkling water with lime

• Unsweetened iced tea with lemon

• Low-carb beer or a keto-friendly hard seltzer
