In a small bowl, combine paprika, garlic powder, onion powder, dried oregano, dried thyme, black pepper, cayenne pepper, and salt to create your Cajun blend.
1 tbsp paprika, 1½ tsp garlic powder, 1 tsp onion powder, 1 tsp dried oregano, 1 tsp dried thyme, 1 tsp black pepper, 1 tsp cayenne pepper, 1 tsp salt
Pat the shrimp dry. Lightly coat with olive oil spray and toss with the Cajun seasoning until evenly coated.
2 lbs raw shrimp, Olive oil spray
Bring a large pot of lightly salted water to a boil. Cook the penne according to package instructions. Before draining, reserve ½ cup of pasta water. Drain and set aside.
8 oz penne pasta
Heat a large skillet over medium-high heat and coat with olive oil spray. Add the shrimp in a single layer (work in batches if necessary to avoid overcrowding). Cook for 2–3 minutes per side until opaque and lightly browned. Transfer shrimp to a plate and reduce heat to medium.
Olive oil spray
Re-spray the skillet lightly if needed. Pour in the half & half, scraping up any browned bits from the bottom of the pan. Bring to a gentle simmer and cook for 2–3 minutes until slightly thickened.
1 cup half & half
Stir in the Parmesan cheese until melted and smooth.
½ cup grated Parmesan cheese
Add the spinach and cook until wilted.
4 cups fresh spinach
Return the cooked shrimp to the skillet along with the drained pasta. Toss to combine. If the sauce is too thick, add reserved pasta water 1 tablespoon at a time until desired consistency is reached.
Divide into 4 equal portions and enjoy.
