In a large pot, bring salted water to a boil and cook noodles al dente (they'll continue to cook with the sauce towards the end)

In a medium bowl, season shrimp with onion powder, garlic powder, Tony's no salt seasoning, garlic and herb seasoning and a drizzle of olive oil. Mix until shrimp is well coated.

Add olive oil to a skillet over medium heat. Sear sausage until browned, about 5 minutes. Once the sausage is cooked, remove from the pan and add in the shrimp. Add more oil if needed. Sear shrimp until cooked, then remove from the pan.

Add 2 tbsp of butter and 1 tbsp of olive oil to the same skillet. Once the butter begins to bubble, add in onions and saute for a few minutes before adding in minced garlic. Saute for an additional 2 minutes.

Add 1 heaping spoonful of sun-dried tomatoes. Whisk in heavy cream and bring to a low simmer. Season with onion powder, garlic powder, smoked paprika, Tony's, garlic and herb seasoning and seasoned salt and pepper to taste. Mix until well combined. Add in a little pasta water if needed.

Reduce heat to low, add cheese mixing continuously until the cheese is melted and well incorporated. Add back in the sausage and shrimp. Then the noodles. Toss until everything is combined. Taste and adjust seasonings if needed.

Top with parsley and more no salt cajun seasoning.

Serve in a bowl and top with fresh lemon juice, parmesan cheese and red pepper flakes if desired. Enjoy!
