- In a bowl, toss shrimp with Old Bay, Cajun seasoning, garlic powder, onion powder, and black pepper.
- Heat 1 tablespoon olive oil in your stock pot over medium-high heat. Cook shrimp for 2–3 minutes per side, just until pink and opaque. Remove the shrimp and set aside.

- Reduce heat to medium-low and simmer for 5–8 minutes until the sauce slightly thickens.
- Add the cooked shrimp and sausage back to the pot (reserve a few pieces to serve on top of pasta if desired). Stir to coat in the sauce.
