How to Make Cajun Lobster and Shrimp Rigatoni
- Start by cooking the rigatoni according to the package instructions until al dente. Once done, drain it and set it aside.
- In a large skillet, heat the olive oil over medium heat. Add the diced onion and bell pepper, and sauté until softened, about 5 minutes.
- Next, stir in the minced garlic and cook for an additional minute until fragrant.
- Now, add the diced tomatoes, heavy cream, and Cajun seasoning to the skillet. Stir well to combine and let it simmer for about 5 minutes.
- Time to add the lobster meat and shrimp! Cook until the shrimp turn pink and are cooked through, about 3-4 minutes.
- Season with salt and pepper to taste. I always suggest tasting as you go to adjust the flavors to your liking!
- Toss the cooked rigatoni with the sauce until it’s all well coated.
- Serve hot, garnished with chopped parsley and a generous sprinkle of grated Parmesan cheese.
Substitutions & Additions
If you’re looking to mix things up, here are some fun swaps and additions:
- Swap out the rigatoni for any pasta shape you love, like penne or fusilli.
- Try adding some spinach or kale for an extra nutritional boost.
- If you want more heat, toss in some diced jalapenos or a dash of hot sauce.
- For a vegetarian version, you can replace the seafood with sautéed mushrooms and zucchini.
Tips for Success
- Be careful not to overcook the shrimp, as they can become rubbery. They only need a few minutes.
- Prep your ingredients ahead of time to make the cooking process smooth and quick.
- If you’re making this dish for a gathering, consider doubling the recipe to serve a crowd.
How to Store Cajun Lobster and Shrimp Rigatoni
If you have leftovers (which is rare, but it can happen!), store them in an airtight container in the refrigerator for up to 3 days. To reheat, simply warm it up on the stovetop over low heat, adding a splash of cream or broth to keep it creamy.
FAQs
Can I use frozen shrimp for this recipe? Absolutely! Just make sure to thaw them before cooking.
