In a large pot of boiling salted water, cook the fettuccine pasta according to package instructions until al dente. Drain and set aside.
In a mixing bowl, toss the shrimp with Cajun seasoning until well coated.
In a large skillet, heat the olive oil over medium-high heat. Add the seasoned shrimp and cook for about 2-3 minutes per side, or until they are pink and cooked through. Remove shrimp from the skillet and set aside.
In the same skillet, add the minced garlic and sauté for 1 minute until fragrant. Pour in the chicken broth and bring to a simmer, scraping up any browned bits from the bottom of the skillet.
Stir in the heavy cream and bring the mixture to a gentle simmer. Let it cook for another 2-3 minutes until slightly thickened.
Add the cherry tomatoes and spinach to the sauce, cooking until the spinach wilts. Then, return the cooked shrimp to the skillet.
Add the cooked fettuccine to the skillet and toss everything together until well combined. Season with salt and pepper to taste.
Plate the pasta and garnish with grated Parmesan cheese and chopped parsley for a fresh touch.
Notes
Serve in large bowls with an extra sprinkle of Parmesan and a slice of lemon on the side for a pop of color.
