Ingredients
For the Main Dish:
- 12 oz fettuccine or linguine
- 1 lb shrimp, peeled and deveined (medium-large)
- 2 tbsp Cajun seasoning
- 2 tbsp olive oil
- 3 tbsp unsalted butter
- 1 medium yellow onion, finely chopped
- 3 cloves garlic, minced
- 1 red bell pepper, thinly sliced
- 1 cup low-sodium chicken broth
- 1 cup heavy cream
- 1/2 cup grated Parmesan cheese
- 2 tbsp fresh lemon juice
- Salt and black pepper to taste
- 2 tbsp chopped fresh parsley for garnish
For the Sauce / Garnish (if applicable):
- Extra grated Parmesan for serving
- Lemon wedges
- Extra Cajun seasoning for those who like more heat
How I Make It
Step 1:
Bring a large pot of salted water to a boil and cook the 12 oz fettuccine until al dente (8–10 minutes) according to package directions. While the water heats, pat 1 lb shrimp dry with paper towels, then toss them with 2 tbsp Cajun seasoning and a pinch of salt. Reserve 1 cup of the pasta cooking water before you drain — that starchy liquid keeps the sauce silky.
Step 2:
Heat a large skillet over medium-high heat and add 2 tbsp olive oil. When it shimmers, add the shrimp in a single layer and sear for about 2–3 minutes total, flipping once. Listen for that satisfying sizzle and watch the shrimp turn opaque and pink. Transfer the shrimp to a plate — don’t worry, they’ll finish in the sauce. Overcooking shrimp ruins the texture, so err on the side of underdone by a minute if you’re unsure.
Step 3:
Lower the heat to medium and add 3 tbsp butter to the same skillet. Toss in the onion and bell pepper and sauté until soft and slightly golden, about 4–5 minutes. Add 3 cloves garlic and cook 30 seconds until fragrant (your kitchen should smell garlicky and irresistible). Pour in 1 cup chicken broth and 2 tbsp lemon juice to deglaze the pan, scraping up any browned bits — that’s where the flavor hides.
Step 4:
Stir in 1 cup heavy cream and bring the mixture to a gentle simmer. Add 1/2 cup Parmesan and whisk until the sauce thickens slightly and coats the back of a spoon, about 2–3 minutes. Toss the drained pasta into the skillet with the sauce, adding reserved pasta water a splash at a time to reach your preferred consistency. Return the shrimp to the pan and toss just until heated through — they should feel firm and juicy, not rubbery.
Step 5:
Finish with 2 tbsp chopped parsley and another squeeze of lemon if you like brightness. Taste and adjust salt, pepper, or Cajun heat. Serve hot with extra Parmesan and lemon wedges on the side. The sauce should cling to every noodle, and the shrimp should pop with each bite.
Pro Tips
- Pat shrimp completely dry before seasoning so they sear and brown instead of steaming.
- Reserve pasta water — that starchy miracle makes the sauce silky without adding cream.
- If your sauce thickens too much, thin with a splash of pasta water or broth; if it’s too thin, simmer a minute until it coats the spoon.
- Need less spice? Use 1 tbsp Cajun seasoning and boost parsley and lemon for brightness.
Common Mistakes to Avoid
- Skipping preheating: Classic rookie move. It changes texture and bake time.
- Overmixing: Leads to dense or chewy results. Mix until just combined.
- Guessing cook time: Always use visual cues or a timer, not just vibes.
- Overcrowding pans: Give your food some breathing room to crisp properly.
Alternatives & Substitutions
- Swap shrimp for chicken or tofu — chicken needs longer (cook to 165°F), tofu soaks up the sauce beautifully but won’t be as tender.
- Replace heavy cream with full-fat Greek yogurt (stir off heat to prevent curdling) for a tangier, lighter sauce.
- Use gluten-free pasta to make it gluten-free; sauce and shrimp remain the same.
- Dairy-free option: use canned coconut milk and a dairy-free Parmesan substitute — expect a slightly tropical flavor.
Variations & Tips
- Spicy: add 1/4 tsp cayenne or an extra pinch of Cajun seasoning for real heat.
- Kid-friendly: cut Cajun to 1 tbsp and sneak in extra Parmesan for cheesy comfort.
- Vegetarian: swap shrimp for sautéed mushrooms and roasted cherry tomatoes.
- Smoky bacon twist: crisp 4 oz chopped bacon and toss in at the end for smoky crunch.
- Lemony herb: add zest of 1 lemon and a handful of chopped basil for a bright finish.
- Tomato cream: stir in 1/2 cup crushed tomatoes for a pink, tangy sauce.
FAQ (Frequently Asked Questions)
- Can I make this ahead of time?
- Yes! Cook the pasta and sauce separately, refrigerate up to 2 days, and reheat gently on the stove with a splash of broth or pasta water. Add shrimp right before serving or reheat briefly to avoid rubbery shrimp.
- Can I double the recipe?
- Sure thing. Use a much larger pot and a wide, heavy skillet (or two skillets) so the shrimp and vegetables cook evenly. You’ll need a little more time for simmering the sauce.
- Can I substitute butter with oil?
- Technically yes, but you’ll miss that buttery magic. Use ¾ the amount of oil.
- How do I know it’s done?
- Shrimp should look opaque and pink with a slightly firm texture and curled shape. The sauce should coat the pasta and leave a glossy trail when you stir — not watery, not clumpy.
- What if I don’t have ingredient X?
- No Cajun seasoning? Mix 1 tsp paprika, 1/2 tsp garlic powder, 1/4 tsp cayenne, and 1/2 tsp onion powder. No heavy cream? Use 4 oz cream cheese blended with 1/2 cup milk, or stir in Greek yogurt off heat for a tangy swap.
How I Like to Serve It
I serve this with a simple green salad tossed in lemon vinaigrette and a chunk of crusty bread to sop up every last drop. A crisp white wine, like Sauvignon Blanc, pairs beautifully. It makes a cozy weeknight meal but also dresses up enough for casual dinner guests or a Sunday family dinner.
Notes
- Store leftovers in an airtight container in the fridge for up to 3 days. Reheat gently on the stove with a splash of broth.
- Cook shrimp until opaque and firm or to an internal temperature of 145°F for safety.
