Step‑by‑Step Instructions for Cajun Beef Spaghetti in Creamy Three-Cheese Parmesan Sauce
Step 1: Boil the Pasta
In a large pot, bring salted water to a rolling boil over high heat. Add spaghetti and cook according to package instructions until al dente, usually about 8-10 minutes. Once done, drain the spaghetti and set it aside, allowing the steam to escape for perfect texture while you prep the next steps.
Step 2: Sear the Beef
While the pasta cooks, toss diced sirloin or ribeye steak with Cajun seasoning until well-coated. In a large skillet, heat 2 tablespoons of butter over medium-high heat until melted and sizzling. Add the seasoned beef, searing it for about 4-5 minutes or until browned on all sides. Remove the beef from the skillet and set it aside, keeping the flavorful drippings.
Step 3: Prepare the Sauce
In the same skillet where you seared the beef, reduce the heat to medium. Add minced garlic and sauté for about 1 minute, just until fragrant but not browned. Pour in 1½ cups of heavy cream, adding cream cheese, mozzarella, and Parmesan. Stir continuously for 3-5 minutes until the sauce is smooth, bubbly, and coats the back of a spoon.
Step 4: Combine Ingredients
Return the browned Cajun beef to the skillet, along with the drained spaghetti. Toss everything together gently for 2-3 minutes, ensuring each strand of spaghetti is coated evenly with the creamy three-cheese sauce. The combination of flavors in this Cajun Beef Spaghetti will delight your taste buds.
Step 5: Garnish and Serve
Once combined, remove from heat and sprinkle with chopped fresh parsley for a pop of color. Serve hot in bowls, optionally topping with extra Parmesan or a dash of Cajun seasoning if desired. This comforting dish is now ready to impress!

How to Store and Freeze Cajun Beef Spaghetti
Fridge: Store leftover Cajun Beef Spaghetti in an airtight container for up to 3 days. This will help preserve its creamy and delicious texture.

Cajun Beef Spaghetti in Creamy Three-Cheese Parmesan Sauce Recipe FAQs
How do I choose the right steak for this recipe?
Absolutely! When selecting steak, look for cuts like sirloin or ribeye that have good marbling for flavor and tenderness. The beef should be bright red with no dark spots. If you’re looking for a more budget-friendly option, ground beef works beautifully as well!
What is the best way to store leftovers?
Very! After cooling, store your Cajun Beef Spaghetti in an airtight container in the refrigerator for up to 3 days. Make sure it’s sealed tightly to maintain its creamy texture and prevent drying out. If you’re like me and often prepare larger batches, it’s best to split it into smaller portions.
Can I freeze Cajun Beef Spaghetti?
For sure! To freeze, let the dish cool completely, then transfer it to a freezer-safe container. You can keep it frozen for up to 2 months. I recommend separating the pasta and sauce if possible, as this helps preserve their individual textures. When you’re ready to enjoy, thaw it overnight in the fridge and reheat gently.
What if my sauce is too thick?
Not a problem! If the sauce becomes too thick while cooking or reheating, simply add a splash of heavy cream or milk. Stir it in gradually until you reach your desired consistency. This little trick will keep it luscious and rich—just as it should be!
Are there any dietary concerns I should be aware of?
Indeed! This recipe contains dairy, so for those with lactose intolerance, use lactose-free versions of cream and cheese. Additionally, if you’re catering to guests with dietary restrictions, consider substituting regular pasta with gluten-free pasta or swapping the beef for shrimp or turkey to meet various preferences.
How can I adjust the spice level of the dish?
Absolutely! If you or your guests prefer a milder flavor, reduce the amount of Cajun seasoning or use a no-heat Cajun blend instead. You can also add a tablespoon of sugar to balance out the spice if it feels too intense. Don’t hesitate to customize it until it’s perfect for your palate!
