This skillet dish has its roots in traditional Cajun cuisine but skips the rice or potatoes that typically accompany it. The result is a protein-rich meal that keeps carbs low while delivering all the characteristic spice and depth that makes Cajun food so craveable. The combination of bell peppers adds color and crunch, while the red onion provides a subtle sweetness that balances the heat from the Cajun seasoning.

• 400g (14 oz) large raw shrimp, peeled and deveined
• 250g (9 oz) andouille or smoked sausage, sliced into 1/2-inch rounds
• 1 large red bell pepper, sliced
• 1 large green bell pepper, sliced
• 1 small red onion, thinly sliced
• 2 cloves garlic, minced
• 2 tbsp olive oil
• 1 tbsp Cajun seasoning (ensure sugar-free for keto)
• 1/2 tsp smoked paprika
• 1/4 tsp cayenne pepper (optional, for extra heat)
• Salt and freshly ground black pepper, to taste
• 2 tbsp chopped fresh parsley
• Lemon wedges, for serving

Step 1

In a large skillet, heat 1 tablespoon of olive oil over medium-high heat. Add the sliced sausage and cook for 3–4 minutes, until browned. Remove sausage and set aside.

Step 2

Add the remaining olive oil to the skillet. Sauté the bell peppers and red onion for 3–4 minutes, until just tender. Add garlic and cook for 1 minute more.

Step 3

Add the shrimp to the skillet, season with Cajun seasoning, smoked paprika, cayenne (if using), salt, and pepper. Cook for 2–3 minutes, stirring, until shrimp turn pink and opaque.

Step 4

Return the sausage to the pan. Toss everything together and cook for an additional 2 minutes to heat through.

Step 5

Remove from heat. Sprinkle with chopped parsley and serve with lemon wedges.

When cooking the shrimp, be careful not to overcook them as they can become tough and rubbery. They're done as soon as they turn pink and opaque. The residual heat from the skillet will continue cooking them slightly even after removing from the heat. If you're using pre-cooked shrimp, add them at the very end just to heat through for about 1 minute.

This recipe is wonderfully adaptable to what you have on hand. For a milder version, reduce the amount of Cajun seasoning and omit the cayenne pepper. For a smoky flavor boost, try using smoked sausage with a higher percentage of fat. You can also swap the andouille for kielbasa or even chicken sausage if you prefer. For a seafood medley, consider adding some bay scallops along with the shrimp.

While this dish is completely satisfying on its own, you can serve it over cauliflower rice for a more traditional presentation that keeps it keto-friendly. A side of simple green salad dressed with olive oil and lemon juice makes a refreshing accompaniment. For those not following a strict keto diet, a slice of crusty bread to soak up the flavorful juices would be a welcome addition.
