Ingredients
- 8 oz (226 g) pasta, such as linguine or spaghetti
- 1 ½ teaspoons smoked paprika
- ¾ teaspoons dried oregano
- ¾ teaspoon dried thyme
- ½ teaspoon dried basil
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ⅛ teaspoon cayenne pepper (adjust for spice preference)
- ¼ teaspoon ground black pepper
- ½ teaspoon table salt, plus more to taste
- 1 lb extra-large shrimp, peeled, deveined, thawed, and patted dry (tails on or off)
- 2 Tablespoons olive oil
- 2 Tablespoons butter, salted or unsalted
- 1 medium yellow onion, diced (about 140 g or 1 cup)
- 2 teaspoons minced garlic (2-3 cloves)
- 1 Tablespoon all-purpose flour
- ⅔ cup (157 ml) chicken broth
- 14.5 oz (411 g) can fire-roasted tomatoes, drained
- ¾ cups heavy cream
- ½ cup (50 g) freshly grated parmesan cheese, plus additional for serving
Instructions
- Bring a large pot of well-salted water to a boil and cook pasta according to package instructions. Once cooked, drain and keep warm until ready to use. Toss with a teaspoon of olive oil to prevent sticking if needed.
- In a small dish, whisk together smoked paprika, oregano, thyme, basil, garlic powder, onion powder, cayenne pepper, black pepper, and salt. Reserve 1 teaspoon of the spice mix for the sauce.
- Place shrimp in a large plastic bag and toss with the remaining Cajun seasoning until fully coated.
- Heat olive oil in a large skillet over medium-high heat. Once hot, sear shrimp in batches, cooking through before transferring to a plate.
- Reduce heat to medium and add butter to the skillet. Once melted, add diced onion and cook until softened, about 3-5 minutes. Add minced garlic and cook until fragrant, about 30 seconds.
- Sprinkle flour and reserved Cajun seasoning over the onion and garlic, stirring until the flour is fully absorbed.
- While stirring, slowly drizzle in chicken broth, scraping the browned bits from the skillet's bottom. Cook until the broth is reduced by half.
- Stir in the fire-roasted tomatoes, followed by the heavy cream until the mixture is well combined.
- Add the cooked pasta and grated parmesan cheese to the skillet. Toss until the pasta is coated and the cheese is melted. Return shrimp to the skillet and cook until warmed through. Serve immediately, topped with additional parmesan cheese if desired.
