Bring a large pot of salted water to a boil. Cook pasta according to package instructions (to al dente). Be sure to reserve 1 cup of the pasta water to use for later if needed.
Add the shrimp to a large mixing bowl and season with oregano, salt, pepper, garlic powder, and onion powder. Set aside.
While the pasta is cooking, place a large skillet over medium heat. Add the butter and oil to the skillet and bring to a low sizzle. Once the butter is melted, add the minced garlic and cook for about 30 seconds, or until fragrant. Add the red crushed peppers and cook for an additional 10-15 seconds.
Add the shrimp to the skillet and cook for 2-3 minutes on each side, or until the shrimp is cooked through. Carefully remove the shrimp from the skillet and set aside.
Drain the pasta and add the drained pasta to the skillet with ¼ cup of the reserved pasta water. Cook and stir the pasta until heated through. If the pasta seems too dry, add a bit more pasta water.
Turn off the heat. Then, add the lemon juice, lemon zest, and freshly grated parmesan cheese. Stir to combine. Then, add the shrimp back to the pasta.
Stir in the fresh parsley and season with salt and pepper to taste.
Serve and enjoy! Top with more freshly grated parmesan cheese and fresh parsley for garnish.
