Prepare the PastaPreheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.Bring a large pot of salted water to a boil. Add the pasta and cook it about 1–2 minutes less than the package directions for al dente. Drain and set aside.2. Season the ShrimpPat the shrimp dry with paper towels. Season with about half of the Cajun seasoning, paprika, black pepper, and a small pinch of salt.3. Sear the ShrimpHeat the olive oil in a large skillet over medium-high heat.Add the shrimp in a single layer and cook briefly on each side until they begin turning pink and opaque. Don't overcook them because they'll finish cooking in the oven.Transfer the shrimp to a plate and set aside.4. Make the Creamy Cajun SauceReduce the heat to medium and melt the butter in the same skillet.Add the minced garlic and cook for about 30 seconds, just until fragrant.Pour in the heavy cream and add the cream cheese. Stir until the cream cheese melts and the sauce becomes smooth.Add the Parmesan and remaining Cajun seasoning. Stir and gently simmer for 2–3 minutes until the sauce begins to thicken.5. Add the SpinachAdd the fresh spinach to the creamy sauce and stir until it wilts.Taste the sauce and adjust the Cajun seasoning, salt, and pepper as needed.6. Combine EverythingAdd the cooked pasta to the skillet and toss until completely coated in the creamy Cajun sauce.Gently fold most of the shrimp into the pasta, reserving a few pieces for the top.7. Assemble the Pasta BakeTransfer the pasta mixture to your prepared baking dish.Arrange the remaining shrimp over the top and sprinkle evenly with mozzarella. Add a little extra Parmesan if desired.8. BakeBake at 375°F (190°C) for 15–20 minutes, or until the sauce is bubbling and the cheese has completely melted.For a more golden cheese topping, broil for 1–2 minutes at the end while watching it carefully.9. ServeAllow the pasta bake to rest for about 5 minutes.Garnish with fresh parsley, Parmesan, and optional red pepper flakes before serving.Recipe NotesDon't overcook the shrimp: Sear them only briefly because they'll continue cooking in the oven.Keep the pasta firm: Slightly undercook your pasta before baking so it doesn't become mushy.Control the heat: Reduce the Cajun seasoning for a milder pasta or add cayenne/red pepper flakes for extra spice.Thick sauce: Add a splash of pasta water, milk, or heavy cream if your sauce becomes too thick.Extra vegetables: Mushrooms, bell peppers, broccoli, onions, or sun-dried tomatoes make great additions.Cheese options: You can substitute Monterey Jack or Pepper Jack for some of the mozzarella.StorageStore leftover Creamy Cajun Shrimp & Spinach Pasta Bake in an airtight container in the refrigerator for up to 3–4 days.When reheating, add a small splash of milk or cream to help restore the creamy consistency of the sauce.
