- Heat the butter, olive oil and garlic in a large skillet over medium-high heat until fragrant, about 1 minute. Add the Cajun seasoning, red pepper flakes, if using, and shrimp and cook, stirring, until the shrimp begin to curl, about 1 minute. Season with salt and pepper.
- Add the Rotel or tomatoes and green onions to the skillet and cook, stirring, about 1 minute. Add the rice and wine (or water, if using) and continue to cook until the rice is heated and the shrimp are opaque, about 3 more minutes. Stir in the parsley and serve with lemon, if desired.
