Ingredients

  

• 1.5 pounds boneless, skinless chicken breasts or thighs, cut into bite-size pieces
• 2 tablespoons Cajun seasoning (store-bought or homemade)
• 1 teaspoon smoked paprika (optional for extra smokiness)
• 1/2 teaspoon garlic powder
• 1/2 teaspoon onion powder
• 1/4 to 1/2 teaspoon cayenne pepper (to taste)
• 1 teaspoon kosher salt, plus more to taste
• 1/2 teaspoon black pepper
• 2 tablespoons olive oil or avocado oil, divided
• 1 red bell pepper, sliced
• 1 yellow bell pepper, sliced
• 1 small red onion, thinly sliced
• 1 medium zucchini, halved lengthwise and sliced
• 2 cloves garlic, minced
• 1 tablespoon tomato paste (optional, for richness)
• 1/2 cup low-sodium chicken broth
• Juice of 1/2 lemon, plus wedges for serving
• 2 tablespoons chopped fresh parsley or green onions
• Optional: 1/2 cup sliced andouille sausage (for extra Cajun flair; adjust carbs as needed)

Instructions

 

• Season the chicken: In a bowl, toss chicken with Cajun seasoning, smoked paprika, garlic powder, onion powder, cayenne, salt, and black pepper. Add 1 tablespoon oil and mix to coat evenly.
• Heat the skillet: Place a large skillet over medium-high heat. Add the remaining tablespoon of oil.
• Sear the chicken: Add chicken in a single layer. Cook 3–4 minutes per side until browned and nearly cooked through. Remove to a plate. If using andouille, sear the slices for 1–2 minutes and set aside with the chicken.
• Sauté the vegetables: In the same skillet, add onion and bell peppers. Cook 3–4 minutes, scraping up browned bits. Add zucchini and cook 2 more minutes.
• Build flavor: Stir in garlic and tomato paste. Cook 30 seconds until fragrant, then pour in chicken broth to deglaze. Scrape the pan bottom with a spoon.
• Finish the skillet: Return chicken (and sausage, if using) to the pan. Toss with the veggies and simmer 2–3 minutes until the chicken is cooked through and the liquid reduces slightly.
• Brighten and serve: Squeeze in lemon juice, taste, and adjust seasoning. Sprinkle with parsley or green onions. Serve hot with extra lemon wedges.

Why This Recipe Works

This skillet brings together lean protein and low-carb vegetables that cook quickly and evenly. The Cajun seasoning adds deep, layered flavor with minimal ingredients and no marinating time.

Everything happens in one pan, so you get fast cleanup and an easy process. Cooking the chicken first builds a flavorful fond, which the veggies pick up for a richer taste. A splash of lemon at the end brightens the dish and balances the spice.

4. Sauté the vegetables: In the same skillet, add onion and bell peppers. Cook 3–4 minutes, scraping up browned bits.

   Add zucchini and cook 2 more minutes.

How to Store

• Refrigerator: Store in an airtight container for up to 4 days.
• Freezer: Freeze for up to 2 months.

  Cool completely, then portion into freezer-safe containers. Thaw overnight in the fridge.

• Reheat: Warm in a skillet over medium heat with a splash of broth or water to keep it juicy. Microwave in short bursts, stirring between intervals.

Benefits of This Recipe

• Low carb and filling: High in protein and fiber-rich veggies to keep you satisfied.
• Quick and practical: From start to finish in about 25–30 minutes.
• One-pan cleanup: Less mess, more time to enjoy dinner.
• Flexible heat level: Adjust the cayenne and Cajun blend to match your spice tolerance.
• Meal-prep friendly: Reheats well and holds its flavor for days.

Common Mistakes to Avoid

• Crowding the pan: Overcrowding prevents browning and leads to steaming.

  Cook chicken in batches if needed.

• Skipping the deglaze: Those browned bits add major flavor. Use broth or water to lift them into the sauce.
• Overcooking the chicken: Pull it when it’s just cooked through. It will finish in the sauce.
• Too much salt: Cajun blends vary in saltiness.

  Taste before adding extra salt.

• Mushy zucchini: Add zucchini later and cook briefly for a tender-crisp bite.

Alternatives

• Protein swaps: Use shrimp, turkey, or tofu. For shrimp, cook 1–2 minutes per side and add at the end to avoid overcooking.
• Veggie swaps: Try mushrooms, asparagus, broccoli, or cauliflower. Keep total cook time similar to avoid soggy textures.
• No tomato paste: Skip it or replace with a tablespoon of sugar-free ketchup for tang without extra carbs.
• No chicken broth: Use water with a pinch of bouillon or a splash of coconut milk for a creamy twist.
• Milder spice: Cut back on cayenne and use sweet paprika instead of smoked.
• Extra heat: Add crushed red pepper or a few dashes of hot sauce at the end.
• Garnish options: Try a dollop of sour cream, sliced avocado, or a sprinkle of shredded cheddar for a richer finish.
• Serving ideas (still low carb): Spoon over cauliflower rice, sautéed cabbage, or a bed of greens.

FAQ

How spicy is this recipe?

It’s moderately spicy with the base Cajun seasoning.

You control the heat with the cayenne and the brand of Cajun blend. For a milder version, reduce or omit the cayenne and choose a mild seasoning mix.

Can I use frozen chicken?

Yes, but thaw it completely and pat it dry before cooking. Excess moisture prevents browning and can water down the sauce.

What’s the best pan to use?

A large cast-iron or stainless steel skillet works best for browning and flavor.

Nonstick is fine, but you’ll get less caramelization.

Is this keto-friendly?

Yes. It’s naturally low in carbs and fits well into a keto or low-carb lifestyle. Watch for added sugars in store-bought Cajun blends.

Can I make it dairy-free?

It’s already dairy-free as written.

If you add creamy elements like sour cream or cheese, choose dairy-free alternatives if needed.

How do I make homemade Cajun seasoning?

Mix 2 tablespoons paprika, 1 tablespoon garlic powder, 1 tablespoon onion powder, 1 tablespoon dried oregano, 1 tablespoon dried thyme, 2 teaspoons black pepper, 2 teaspoons cayenne (to taste), and 2 teaspoons salt. Store in a jar.

What if I don’t have zucchini?

Use mushrooms, broccoli florets, or green beans. Keep pieces small so they cook quickly without softening too much.

How can I add more sauce without extra carbs?

Reduce an extra 1/2 cup broth in the pan with the tomato paste and spices.

You can also whisk in a small knob of butter at the end for a glossy finish.

Can I grill the chicken instead?

Yes. Grill seasoned chicken pieces, then slice and toss with sautéed veggies and a splash of broth or lemon in a skillet to combine flavors.

What pairs well with this dish?

Cauliflower rice, a mixed green salad, roasted Brussels sprouts, or sautéed cabbage make great low-carb sides. Keep the seasoning simple to let the Cajun flavors shine.
