Bring a large pot of salted water to a boil. Add the pasta and cook, stirring frequently, until al dente, about 9 minutes. Drain the pasta and set aside.
2. Step
In the same pot, heat 2 tablespoons of butter over medium heat. When the butter has melted, add the shrimp and season with the Zesty seasoning. Cook until the shrimp start to turn pink, but are not fully cooked, about 3 minutes. Add the spinach and cook until wilted, about 3 minutes.
3. Step
Add the linguine to the pot, along with the remaining 6 tablespoons of butter and Parmesan. Toss until the butter melts and the pasta is well-coated. Add the lemon juice and toss once more to incorporate.
