Heat olive oil in a skillet over medium heat. Add diced onion and bell pepper, sauté until softened, about 5 minutes.

Stir in minced garlic and sauté for an additional minute until fragrant.

Add the shrimp to the skillet and sprinkle with Cajun seasoning. Cook until shrimp are pink and opaque, about 5-7 minutes.

Pour in chicken broth and let simmer for 2-3 minutes to combine flavors.

Serve the Cajun shrimp over cooked rice or pasta.
