- Begin boiling a lightly salted pot of water. Prepare the pasta according to package instructions. When draining, reserve 1/2 cup in case you want to thin out the sauce.8 oz Penne pasta
- Heat a large skillet with the butter over medium-high heat. Sauté the shrimp for 3-4 minutes on each side, flipping when halfway through. Be careful not to crowd the skillet, cooking in two batches with 1 tbsp of butter in each if needed. This is to ensure you get a nice crispy coating on each side of the shrimp.2 tbsp Salted Butter
- Once the shrimp is cooked through, transfer to a clean plate & reduce the heat to medium.
- Add the heavy cream to the skillet, scraping the bottom with a rubber spatula or wooden spoon to release the seasonings stuck to the bottom of the skillet. Bring the heavy cream to a light boil, then reduce heat to low. Stir in the parmesan cheese until melted & well incorporated.1 cup Heavy cream, 1/2 cup Parmesan cheese
- Add spinach to the sauce, stirring until wilted. Then, return shrimp to the skillet with your cooked & drained pasta. Stir to coat. If the sauce is too thick, add your reserved pasta water 1 tbsp at a time. Once sauce is at desired thickness, separate into 4 equal portions & enjoy!4 cups Spinach

🌿 Ingredient Substitutions & Customizations
Tailor this recipe to fit your dietary preferences and pantry staples:
- Swap the Protein: Chicken breast, tofu, or seared scallops all work great in place of shrimp.
- Make It Lighter: Use half-and-half instead of heavy cream or skip the butter altogether.
- Dairy-Free: Sub the cream with full-fat coconut milk and use a plant-based parmesan.
- More Veggies: Add mushrooms, bell peppers, or zucchini to boost fiber and volume.
- Lower the Heat: Cut back on cayenne and Cajun seasoning if you’re spice-sensitive.
🔥 Expert Tips for Perfect Cajun Shrimp Pasta
- Pat the Shrimp Dry: Helps the seasoning stick and gives you a better sear.
- Cook in Batches: Overcrowding leads to steaming instead of searing.
- Reserve Pasta Water: It’s liquid gold for adjusting sauce thickness and texture.
- Grate Fresh Parmesan: It melts better and adds deeper umami flavor.
- Balance the Heat: A squeeze of lemon juice at the end can brighten up the richness.

❓ FAQs
Can I use pre-cooked shrimp?
You can, but the texture may not be as firm or flavorful. If using pre-cooked, skip the sautéing step and add them just before combining everything to avoid overcooking.
Is this dish very spicy?
It has a medium heat level. Omit the cayenne for a milder version or adjust to your liking.
Can I make it gluten-free?
Yes! Use gluten-free penne or a chickpea-based pasta and double-check that your Cajun seasoning and parmesan are GF.
What can I use instead of heavy cream?
Try evaporated milk, half-and-half, or a dairy-free alternative like coconut cream.
Does it reheat well?
Absolutely. The cream-based sauce holds up nicely with a little water or milk added during reheating.
