๐ชInstructions To Make Cajun Shrimp Pasta
- Boil the Pasta: Start by bringing a large pot of salted water to a boil. This is key to seasoning the pasta as it cooks.
- Cook the Pasta: Once the water is boiling, add the fettuccine and cook until al dente, following the package instructions. Don't forget to reserve about ยฝ cup of pasta water before draining.
- Sautรฉ the Aromatics: While the pasta cooks, melt the butter in a large skillet or Dutch oven over medium heat. Add the shallots and sautรฉ for 2-3 minutes until softened, then add the garlic and cook for an additional minute, making sure not to let them brown.
- Cook the Shrimp: Increase the heat to medium-high, add the shrimp, and season with half of the Cajun seasoning. Cook for 2-3 minutes on each side, until the shrimp are pink and cooked through. Remove the shrimp from the pan and set aside.
- Make the Sauce: Lower the heat to medium and add the diced tomatoes to the pan, cooking for 1-2 minutes. Pour in the heavy cream and water, then season with the remaining Cajun seasoning, cream cheese, and a pinch of black pepper. Whisk everything together until the cream cheese is melted and the sauce is smooth.
- Combine Everything: Add the cooked pasta and shrimp back into the pan with the sauce. Toss until everything is well coated. If the sauce is too thick, gradually stir in the reserved pasta water, a tablespoon at a time, until it reaches your preferred consistency.
- Finish and Serve: Sprinkle the chopped parsley into the pan and let it simmer for another minute. Serve your Creamy Cajun Shrimp Pasta garnished with extra parsley or a dash of Cajun seasoning for an added kick.
๐Variations
- Swap the shrimp:ย Chicken,ย scallops,ย or even smoked sausage can replace the shrimp for a protein twist.ย Season accordingly to maintain the Cajun vibe.
- Add Bell pepper:ย Add chopped bell peppers (red,ย yellow,ย or orange) during the shallot sauteing for added sweetness and color.
- Mushroom:ย Saute sliced mushrooms with the shallots for an earthy depth of flavor.
- Lighten up:ย Substitute half-and-half for heavy cream for a slightly lighter option
- Cheese it up:ย Grated Parmesan,ย cheddar,ย or mozzarella can be added to the sauce for an extra cheesy indulgence.
๐Storage
- Refrigeration: Allow any leftover pasta to cool to room temperature. Transfer it to an airtight container and store it in the refrigerator for up to 3-4 days.
- Reheating: When ready to enjoy the leftovers, you can reheat the pasta in a skillet over medium heat, stirring occasionally until heated through. Alternatively, you can microwave it in short intervals, stirring in between, until heated to your liking.
๐ญTop Tip
- Season Shrimp Well: Make sure to season the shrimp generously with Cajun seasoning before cooking to ensure they are flavorful and spicy.
- Don't Overcook the Shrimp: Shrimp cook quickly, so be careful not to overcook them. They should be pink and opaque when done, usually in just a few minutes.
- Adjust Cajun Seasoning to Taste: Cajun seasoning can vary in spiciness, so taste the sauce before adding the cooked shrimp and adjust the seasoning accordingly to your preferred level of heat.
- Use Heavy Cream Wisely: Be cautious when adding heavy cream to the sauce, as too much can make it overly rich. Start with a small amount and add more as needed to reach your desired creaminess.
- Customize the Pasta: Feel free to add extra ingredients like bell peppers, mushrooms, or spinach to the pasta for added flavor and nutrition.
- Cook Pasta Al Dente: Cook the pasta just until al dente, as it will continue to cook slightly when combined with the sauce. This helps prevent the pasta from becoming mushy.
- Garnish Thoughtfully: Garnish the finished dish with chopped parsley and grated Parmesan cheese for added flavor and a pop of color.
- Serve Immediately: Creamy pasta dishes are best served immediately after cooking to prevent the sauce from becoming too thick or the shrimp from overcooking.
