What You’ll Need

• Chicken: 4 boneless, skinless chicken thighs (about 1.25–1.5 lb) or 2 large chicken breasts sliced into cutlets
• Fat for cooking: 2 tablespoons olive oil or avocado oil
• Butter: 2 tablespoons, for richness
• Garlic: 3 cloves, minced
• Onion: 1/2 small yellow onion, finely diced (optional but recommended)
• Bell pepper: 1 small red or orange, thinly sliced (optional for color and crunch)
• Chicken broth: 1/2 cup, low sodium
• Heavy cream: 3/4 cup
• Cream cheese: 2 tablespoons, softened (helps thicken without flour)
• Parmesan: 1/4 cup freshly grated
• Lemon juice: 1–2 teaspoons, to brighten the sauce
• Fresh herbs: Chopped parsley or green onions for garnish
• Sea salt and black pepper: To taste

Cajun Seasoning (Homemade)

• 2 teaspoons smoked paprika
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1 teaspoon dried oregano
• 1 teaspoon dried thyme
• 1/2–1 teaspoon cayenne pepper (adjust for heat)
• 1/2 teaspoon ground black pepper
• 1/2 teaspoon fine sea salt

Note: You can use 1–1.5 tablespoons of your favorite store-bought Cajun seasoning, but check the label to avoid added sugars or fillers.

Step-by-Step Instructions

1. Prep the chicken: Pat the chicken dry.

   Season both sides with salt, pepper, and about half of the Cajun seasoning. This helps lock in flavor and creates a nice sear.

2. Heat the pan: Set a large skillet over medium-high heat. Add the oil.

   When shimmering, add the chicken in a single layer.

3. Sear the chicken: Cook thighs 4–5 minutes per side (cutlets 3–4 minutes per side) until browned and cooked through. Transfer to a plate and tent loosely with foil.
4. Sauté aromatics: Reduce heat to medium. Add butter to the pan.

   Stir in onion and bell pepper if using; cook 3–4 minutes until softened. Add garlic and cook 30 seconds until fragrant.

5. Deglaze: Pour in chicken broth and use a wooden spoon to scrape up browned bits. Let it simmer 1–2 minutes to reduce slightly.
6. Make it creamy: Lower heat to medium-low.

   Whisk in heavy cream and cream cheese until smooth. Stir in the remaining Cajun seasoning and Parmesan. Simmer gently 2–3 minutes, stirring, until the sauce thickens.

   Avoid boiling.

7. Finish and adjust: Return the chicken and any juices to the pan. Spoon sauce over the pieces and simmer 1–2 minutes to warm through. Add lemon juice to taste.

   Adjust salt, pepper, and cayenne if needed.

8. Serve: Garnish with parsley or green onions. Pair with cauliflower rice, sautéed spinach, roasted broccoli, or zucchini noodles.

Storage Instructions

• Refrigerator: Store in an airtight container for up to 4 days.
• Freezer: Freeze for up to 2 months. The sauce may separate slightly after thawing; whisk while reheating to bring it back.
• Reheat: Warm gently in a covered skillet over low heat or in the microwave at 50% power in short intervals, stirring between bursts.

  Add a splash of broth or cream if the sauce is too thick.

Health Benefits

• Keto-friendly macros: Rich in protein and healthy fats, this dish helps maintain satiety and supports low-carb goals.
• Blood sugar friendly: With minimal carbs and no added sugar, it’s a good option for stable energy and fewer cravings.
• Nutrient density: Chicken provides B vitamins and selenium; herbs and spices add antioxidants; dairy contributes calcium and fat-soluble vitamin absorption.
• Customizable sodium and spice: Making your own seasoning lets you control salt and heat.

Pitfalls to Watch Out For

• Overcooking the chicken: Dry chicken makes the dish less enjoyable. Use an instant-read thermometer; aim for 165°F at the thickest part.
• Boiling the cream sauce: High heat can cause separation or a grainy texture. Keep it at a gentle simmer.
• Too salty seasoning blends: Many Cajun blends are heavy on salt.

  Taste as you go and season gradually.

• Hidden sugars and starches: Some store-bought mixes include sugar or cornstarch. Read labels or use the homemade blend.
• Skipping the deglaze: Those browned bits are flavor gold. Don’t miss that step for a deeper, richer sauce.

Alternatives

• Protein swaps: Use shrimp (cook quickly, set aside), salmon fillets, pork chops, or firm tofu for a vegetarian spin.
• Dairy-free: Replace butter with ghee or avocado oil, and use full-fat coconut milk instead of cream.

  Skip Parmesan or use a dairy-free alternative. Expect a slightly sweeter, coconut-forward profile.

• Extra veggies: Add spinach, mushrooms, or zucchini to the pan after the aromatics for more volume and fiber.
• Lower heat: Reduce cayenne and add smoked paprika for warmth without too much spice.
• Thicker sauce: Simmer 2–3 minutes longer or whisk in a bit more cream cheese. For ultra-smooth texture, blend part of the sauce and return to the pan.
• Herb twist: Finish with fresh basil or thyme for a different flavor angle.

FAQ

Is this recipe spicy?

It has a gentle kick, but the heat level depends on your cayenne amount and the Cajun blend you use.

Start with less and add more at the end if you like it spicier.

Can I make it ahead?

Yes. Cook fully, cool, and store in the fridge for up to 4 days. Reheat gently and thin with a splash of broth or cream if needed.

What can I serve this with that’s keto-friendly?

Cauliflower rice, sautéed kale or spinach, roasted asparagus, zucchini noodles, or a simple side salad with olive oil and lemon work well.

Can I use half-and-half instead of heavy cream?

You can, but the sauce will be thinner and more likely to separate.

If using half-and-half, keep the heat low and add a bit more cream cheese to help thicken.

How do I prevent the sauce from breaking?

Keep the heat moderate, add dairy after reducing the broth, and avoid boiling. Stir regularly and finish with lemon off the heat or at a gentle simmer.

Breasts or thighs—which is better?

Thighs are more forgiving and stay juicy. If using breasts, slice into cutlets for even cooking and keep a close eye on temperature.

Can I use pre-cooked chicken?

Yes.

Warm it in the finished sauce for a few minutes. You won’t get the same seared flavor, so consider adding a touch more Cajun seasoning.
