Ingredients You’ll Need
This Lightened Creamy Cajun Shrimp Pasta Recipe only calls for simple, essential ingredients, but each one plays a big role in building layers of flavor and texture. From tender shrimp to creamy sauce components and vibrant baby spinach, every element is thoughtfully chosen to create a balanced and satisfying meal.
- Spaghetti (16 oz): The perfect base that soaks up all the delicious sauce, giving you every bit of flavor in each forkful.
- Shrimp (1 lb, peeled and deveined): Tender and juicy, shrimp is a quick-cooking protein that pairs wonderfully with Cajun spice.
- Cajun seasoning (¼ cup, divided): Adds that smoky, spicy kick that defines the dish’s personality—half goes on the shrimp, half into the sauce.
- Salt and black pepper (pinch): To enhance all the natural flavors without overpowering them.
- Olive oil (1 tablespoon): Provides a light, fruity base for cooking the shrimp without adding heaviness.
- Butter (1 tablespoon): Brings a touch of richness to the sauce, balancing out the spices.
- Garlic (3 cloves, minced): Infuses the sauce with its warming aroma and depth.
- Diced tomatoes (2 cans, 14 oz each, undrained): Adds acidity and texture, making the sauce vibrant and slightly tangy.
- Milk (2 cups): The lighter creamy component of this recipe, giving smoothness without heavy cream.
- All-purpose flour (2 tablespoons): Used to thicken the sauce, creating that velvety texture everyone loves in creamy pasta dishes.
- Grated Parmesan cheese (½ cup): Adds a savory, nutty umami punch that elevates the entire dish.
- Baby spinach (8 oz bag): Injects freshness, color, and a boost of nutrients without changing the flavor profile.
- Fresh parsley (for garnish): Finishes the dish with a pop of herbal brightness.
How to Make Lightened Creamy Cajun Shrimp Pasta Recipe
Step 1: Cook Pasta
Start by boiling your spaghetti according to the package directions until it’s perfectly al dente. This will give you pasta that’s firm enough to hold the sauce without becoming mushy. Once cooked, drain and keep it warm so it’s ready to absorb the flavorful sauce later.
Step 2: Season Shrimp
Next, toss your peeled and deveined shrimp in half of the Cajun seasoning along with a pinch of salt and black pepper. This crucial step infuses the shrimp with that smoky, spicy Cajun essence that will make every bite memorable.
Step 3: Cook Shrimp
Heat olive oil in a large Dutch oven over medium-high heat, then cook the shrimp just until they turn opaque—this only takes a few minutes. Overcooking will make shrimp rubbery, so keep a close eye on them. Once done, set the shrimp aside to add back into the sauce at the end.
Step 4: Make Sauce
In the same pot, melt butter and cook minced garlic until it’s fragrant and inviting. Then, add diced tomatoes with their juices and the milk, letting these simmer together. This slow melding of ingredients builds an inviting, rich base for your lightly creamy sauce.
Step 5: Thicken Sauce
To achieve that luxuriously creamy texture without heavy cream, whisk ¼ cup of the milk mixture with flour separately to form a smooth roux. Gradually add this back into the pot, whisking constantly until the sauce thickens beautifully without lumps.
Step 6: Add Flavor
Stir in the grated Parmesan cheese along with the remaining Cajun seasoning. The cheese melts into the sauce, adding a savory undertone that balances the heat from the spices. Let it simmer over medium heat to deepen the flavors, stirring occasionally to prevent sticking. Then turn off the heat.
Step 7: Combine and Finish
Finally, return the cooked shrimp to the pot along with the drained spaghetti. Toss everything together until every strand is coated in that creamy, spicy sauce. Stir in the baby spinach and let it wilt gently from the heat of the sauce—this adds a beautiful burst of green and a fresh taste to the dish.
Step 8: Serve
Garnish your pasta with freshly chopped parsley and a sprinkle of extra Parmesan cheese to elevate the visual appeal and flavor. Serve immediately while warm, so every bite is as comforting and delicious as it can be.
How to Serve Lightened Creamy Cajun Shrimp Pasta Recipe
Garnishes
Fresh parsley not only adds a lovely pop of color but also a slight herbal brightness that cuts through the rich, spicy sauce. A little extra grated Parmesan on top enhances that cheesy, savory depth, making your dish even more irresistible and restaurant-worthy.
Side Dishes
To round out this Lightened Creamy Cajun Shrimp Pasta Recipe, consider serving it with a crisp green salad tossed in a tangy vinaigrette or some roasted vegetables like asparagus or broccoli. The lightness and crunch from these sides perfectly balance the creamy, spicy pasta and keep the meal feeling fresh.
Creative Ways to Present
For a fun twist, serve the pasta in individual shallow bowls to showcase the colorful shrimp and vibrant spinach. You could also add a wedge of lemon on the side—squeezing it just before eating adds a zesty brightness that plays beautifully off the Cajun spices.
Make Ahead and Storage
Storing Leftovers
Leftovers from this Lightened Creamy Cajun Shrimp Pasta Recipe keep well in an airtight container in the refrigerator for up to three days. Keep the shrimp and pasta together to maintain the sauce’s creamy texture, but when reheating, do it gently to avoid overcooking the shrimp.
Freezing
Freezing isn’t ideal for this recipe because the texture of the shrimp and pasta can change when thawed. However, if you must, store the cooked pasta and shrimp in a freezer-safe container for up to one month, then thaw overnight in the fridge before reheating gently.
Reheating
Reheat leftovers on the stove over low heat, adding a splash of milk or water to loosen the sauce if it thickens too much. Stir gently to warm through evenly and avoid rubbery shrimp or mushy pasta. Microwaving works too but heat in short bursts and stir in between for best results.
FAQs
Can I use a different type of pasta for this recipe?
Absolutely! While spaghetti works beautifully here, feel free to use penne, fettuccine, or even whole wheat pasta for a slightly different texture and whole-grain option.
Is this recipe very spicy?
The Cajun seasoning adds a nice kick, but you can always adjust the amount to suit your heat preference. Using half for the shrimp and half for the sauce balances spiciness without overwhelming the dish.
Can I substitute heavy cream for milk if I want it richer?
Yes, swapping milk for heavy cream will create a richer and thicker sauce, but keep in mind it also increases the calorie count. The milk version is an intentional lightened approach without sacrificing creaminess.
How do I make sure the shrimp stays tender?
Cook shrimp just until they turn opaque, which usually takes 2-3 minutes per side. Overcooking makes shrimp tough, so remove them promptly and add back to the sauce at the end to warm through gently.
Can I prepare parts of this recipe ahead of time?
You can cook and toss the shrimp in seasoning ahead, and even boil the pasta earlier. Just store them separately in the fridge and combine with the freshly made sauce right before serving for the best texture and flavor.
