Step‑by‑Step Instructions for Crawfish Monica
Step 1: Prep Ingredients
Begin by finely chopping the shallot, red bell pepper, green onions, and parsley, and mincing the garlic. Grate the Parmesan cheese for a creamy finish. In a separate pot, bring salted water to a boil for the rotini pasta, as you’ll want it ready to go while you prepare the savory sauce.
Step 2: Sauté Vegetables
In a large skillet over medium heat, pour in the extra virgin olive oil and melt 2 tablespoons of unsalted butter. Once hot, add the chopped shallots, red bell pepper, and half of the green onions. Sauté for about 8 minutes, or until the vegetables are softened and fragrant, then stir in the minced garlic for an additional minute, allowing it to become aromatic.
Step 3: Make Sauce
Reduce the heat to low, then stir in the cooked crawfish tails, heavy cream, grated Parmesan cheese, chopped parsley, and Cajun seasoning. Allow the mixture to simmer gently for 10-15 minutes, stirring occasionally, until the sauce thickens and becomes luscious. You’ll know it’s ready when it clings generously to the back of a spoon.
Step 4: Cook Pasta
While the sauce is thickening, add the rotini pasta to the boiling salted water and cook according to package directions until al dente, typically around 8-10 minutes. Once cooked, reserve ½ cup of the pasta water to help blend the dish later, then drain the rest and set the pasta aside in the pot.
Step 5: Combine
Add the drained rotini pasta directly into the creamy sauce in the skillet. Mix in a splash of the reserved pasta water and the remaining green onions, tossing everything together gently over low heat for 1-2 minutes. The pasta should be well-coated with the rich Crawfish Monica sauce, creating a delightful, creamy texture.
Step 6: Serve
Plate the decadent Crawfish Monica immediately, ensuring each serving is generously topped with extra sauce. Garnish with fresh parsley for a pop of color and serve hot, ideally alongside warm garlic bread to complement this rich, flavorful feast.

Make Ahead Options
Crawfish Monica is perfect for busy home cooks who want to save time without sacrificing flavor! You can prep the sautéed vegetables and the creamy sauce up to 24 hours in advance. Simply cook the sauce and allow it to cool completely before transferring it to an airtight container and refrigerating. The cooked crawfish will retain their deliciousness, but to maintain the sauce’s creamy texture, avoid reheating in the microwave; instead, warm it gently on the stovetop, adding a splash of heavy cream or reserved pasta water as needed. When ready to serve, boil the rotini and combine everything for a quick, satisfying meal that’s just as delightful as if it were freshly made!
Storage Tips for Crawfish Monica
Fridge: Store leftovers in an airtight container for up to 3 days. Let cool completely before sealing to maintain freshness.

Reheating: Reheat gently on the stove over low heat, adding a splash of cream or broth to restore creaminess. Avoid using the microwave, as it can break the sauce.
Leftover Usage: Consider transforming unused Crawfish Monica into a flavorful pasta bake. Just mix with parmesan and breadcrumbs, then bake until golden!

Crawfish Monica Recipe FAQs
What should I look for when selecting crawfish?
Absolutely! When choosing crawfish, look for those that are firm and have a clean, briny scent. Avoid any that have dark spots all over the shells, as this may indicate spoilage. If you’re opting for frozen crawfish, ensure they appear whole and are properly sealed.
How should I store leftover Crawfish Monica?
For best results, store any leftovers in an airtight container in the refrigerator for up to 3 days. Make sure the dish cools completely before sealing to lock in freshness. It’s a delightful dish to enjoy again!
Can I freeze Crawfish Monica?
Not recommended! Due to its creamy sauce, freezing can cause the texture to break down upon thawing. If you’re looking for ways to use leftovers, I suggest transforming them into a delicious pasta bake instead!
What should I do if my sauce is too thick?
Don’t worry! If your Crawfish Monica sauce thickens more than you’d like, simply stir in a splash of the reserved pasta water over low heat. This allows you to adjust the creaminess to your preference while ensuring it blends seamlessly.
Is Crawfish Monica suitable for those with shellfish allergies?
Definitely be cautious! Since this dish contains crawfish, it’s not suitable for individuals with shellfish allergies. However, you can swap the crawfish for another protein, such as chicken or sautéed veggies, for a different yet equally delicious experience.
How can I enhance the flavor of my Crawfish Monica?
Very! For an extra depth of flavor, consider adding a splash of white wine to your sautéed vegetables. Let it reduce slightly before adding in the cream and crawfish, giving your sauce a wonderfully rich profile that truly sings with Cajun essence.
