High protein Cajun chicken rice is the kind of recipe that makes you feel like you actually have your weeknight dinners figured out. It is bold, creamy, filling, and packs 53 grams of protein into every serving. I started making this on meal prep Sundays and it quietly became the most requested dinner in my weekly rotation.
The first time I made it, I was not sure a homemade Cajun seasoning blend would be worth the extra step. It absolutely is. The spices soak into the chicken overnight, the cream sauce comes together in minutes right in the same pan, and the whole thing lands on the table in about 50 minutes. High protein Cajun chicken rice hits every note: spicy, creamy, satisfying, and genuinely good for you. You are going to love this one!

Ingredients for High Protein Creamy Cajun Chicken Rice
Every ingredient in this recipe earns its place, and the homemade Cajun seasoning is what makes the whole dish sing. I always use smoked paprika instead of regular because it adds a deeper, almost smoky warmth that store-bought blends rarely get right.
Cajun Seasoning Mix:
- 1 tsp salt
- 1 tsp black pepper
- 1 tsp garlic powder
- 1 tsp onion powder
- 1 tsp dried oregano
- 1 tsp dried thyme
- 1 tsp smoked paprika – I recommend smoked over regular for the richest flavor
- 1 tsp chili powder
Chicken:
- 1.75 lbs chicken breast (cut into halves for even cooking)
- 1.5 tbsp Cajun seasoning mix (from above, for marinating)
- 2 tsp olive oil
Rice Base:
- 2 tbsp grass-fed butter (for sauteing onion and garlic)
- 1 medium red onion (chopped)
- 4 to 5 cloves garlic (chopped) – In my experience, chopped garlic gives better texture than minced here
- 0.5 tbsp Cajun seasoning mix
- 3 cups day-old cooked rice (white or brown) – My preference is day-old rice since it fries up without clumping
Cream Sauce:
- 1 tbsp grass-fed butter
- 0.5 tbsp Cajun seasoning mix
- 1 cup whole milk (plus a splash more if needed to loosen the sauce)
- 5.3 oz light cream cheese (cut into small chunks for easier melting)
- 1.4 oz Parmesan cheese (freshly grated) – I usually grate my own for the smoothest, silkiest sauce
- Fresh parsley (chopped, for garnish)
Step-by-Step Instructions
I recommend marinating the chicken the night before whenever you can. That one small step makes a genuinely noticeable difference in how bold the Cajun flavor comes through.
Step 1: Combine all Cajun seasoning ingredients in a small bowl and stir to blend. Place chicken breast halves in an airtight container, add 1.5 tablespoons of the seasoning mix and the olive oil, and coat thoroughly. Cover and refrigerate overnight for best results, or for a minimum of 30 minutes if you are short on time.
Step 2: Heat a large 12-inch skillet or cast iron pan over medium-high heat. Add 2 tablespoons of butter and let it melt. Add the marinated chicken and cook for 6 to 7 minutes per side until deeply golden brown on the outside and the internal temperature reaches 165 degrees F on a meat thermometer. Remove from the pan and let rest for 5 minutes before slicing into strips. Do not skip the rest or the juices will run straight out when you cut.
Step 3: In the same pan, lower the heat to medium. Add the chopped red onion and cook for 3 to 4 minutes until softened and translucent. Add the chopped garlic and cook for 1 minute until fragrant. The pan should smell incredible at this point.
Step 4: Sprinkle 0.5 tablespoon of Cajun seasoning into the pan and stir for 30 seconds to toast the spices slightly. Add the day-old rice and toss everything together for 2 to 3 minutes until the rice is heated through and fully coated.
Step 5: Lower the heat to medium-low. Add 1 tablespoon of butter and let it melt. Add the remaining 0.5 tablespoon of Cajun seasoning and slowly pour in the milk while whisking constantly to keep things smooth. Do not rush this step or the sauce can separate.
Step 6: Once the milk is warm, add the cream cheese chunks and stir until fully melted and smooth. Add the freshly grated Parmesan and stir until the sauce is silky and glossy. If it looks too thick, add a small splash of milk and stir to loosen.
Step 7: Plate the seasoned rice, layer the sliced Cajun chicken on top, and drizzle the creamy sauce generously over everything. Finish with fresh chopped parsley and serve hot.

Best Sides to Serve with High Protein Cajun Chicken Rice
This dish is bold and creamy on its own, so the best pairings bring freshness, crunch, or a light contrast to balance the richness of the sauce.
Simple Green Salad: A crisp salad with lemon vinaigrette cuts right through the richness of the Cajun cream sauce and keeps the overall meal feeling balanced rather than heavy.
Broccoli and Mushroom Stir Fry: This quick veggie stir fry adds color, fiber, and a satisfying earthiness that works really well alongside the spicy, creamy Cajun flavors.
Easy Chicken Breast and Green Beans: A clean and simple protein and vegetable combo that adds nutritional balance to the plate without competing with the bold Cajun seasoning.
Garlic Roasted Vegetables: A sheet pan of roasted vegetables with garlic is one of the easiest sides you can make and the caramelized edges pair naturally with the smoky Cajun spices.
Honey BBQ Chicken Rice: If you are cooking for a group with varying spice tolerances, this milder sweet and savory chicken rice is a great companion dish to serve alongside for the kids.
Easy Garlic Bread with Sliced Bread: Warm garlic bread is the perfect tool for scooping up the extra Cajun cream sauce left on the plate. My family never lets a drop go to waste.
How to Store and Reheat Your Cajun Chicken Rice
Store leftovers in airtight containers in the refrigerator for up to 3 days. For meal prep, I recommend keeping the rice, sliced chicken, and cream sauce in separate containers. Each component stays at its best texture when stored apart and reheated individually throughout the week.
To reheat, warm gently in a pan over medium-low heat with a small splash of milk stirred into the rice and sauce. This keeps the cream sauce from separating and prevents the rice from drying out. The microwave also works in 2 to 3 minute intervals with a damp paper towel placed over the top to trap steam.
Pro tip: the flavors in this high protein Cajun chicken rice actually deepen overnight, so leftovers often taste even bolder than the first serving. It is one of the best recipes you can make for a week of satisfying, high-protein lunches.
FAQs
Can I use store-bought Cajun seasoning instead of making my own?
Yes. Substitute with your favorite store-bought blend using the same total amounts called for in the recipe. Making your own gives you full control over the salt level and heat, which matters a lot in a dish like this.
What type of rice works best in this recipe?
Day-old white or brown rice both work well. Day-old rice is drier, absorbs the seasoning more evenly, and holds up better when tossed in the pan. Freshly cooked rice tends to clump and get mushy.
Can I make this dairy-free?
You can substitute the butter with a plant-based alternative and use unsweetened oat milk in place of whole milk. Dairy-free cream cheese works in the sauce, though the final texture will be slightly lighter and less rich than the original.
Conclusion
This high protein Cajun chicken rice is the kind of weeknight dinner that earns a permanent spot in your regular rotation. Bold spices, a creamy Parmesan sauce, and 53 grams of protein per serving make it a meal you will actually look forward to eating, and reheating. Give it a try this week and let me know how it turned out. Enjoy every bite!
