What Kind of Parmesan Cheese Should I Use?

For this recipe, freshly grated Parmesan is the way to go. Pre-shredded or canned Parmesan tends to be drier and doesn’t melt as smoothly. If you want your sauce silky and luxurious, splurge on a block of high-quality Parmesan and grate it yourself. It makes a world of difference in both taste and texture.

Ingredients for the Cajun Beef Spaghetti in Creamy Three-Cheese Parmesan Sauce

To build the rich, savory layers of flavor in this dish, you’ll need a blend of quality ingredients. Each one plays a key role in creating the balance between spice, creaminess, and heartiness. Here’s what you’ll need:

• Ground beef: Provides the meaty base and hearty flavor.
• Spaghetti: The classic pasta that holds up well in creamy sauces.
• Cajun seasoning: Brings heat and spice, giving the dish its signature kick.
• Cream cheese: Adds a velvety texture and slight tang that enhances the sauce.
• Mozzarella cheese: Offers melty, gooey stretch and mild flavor.
• Parmesan cheese: Lends a sharp, salty bite that deepens the sauce’s flavor.
• Heavy cream: The foundation of the rich sauce that ties everything together.
• Garlic: Boosts the savory notes and adds aromatic depth.
• Onion: Builds the flavor base when sautéed with the beef.
• Olive oil: Used for cooking the aromatics and beef.
• Salt and pepper: Essential for balancing the seasoning.

How To Make the Cajun Beef Spaghetti in Creamy Three-Cheese Parmesan Sauce

Step 1: Brown the Beef and Aromatics

Heat olive oil in a large skillet over medium-high heat. Add diced onion and cook until translucent. Toss in minced garlic and cook for an additional 30 seconds. Add ground beef and cook until browned, breaking it apart with a spoon. Season with Cajun seasoning, salt, and pepper.

Step 2: Cook the Pasta

While the beef cooks, bring a pot of salted water to a boil and cook the spaghetti according to package instructions until al dente. Reserve about a cup of the pasta water, then drain.

Step 3: Make the Creamy Cheese Sauce

Reduce the skillet to medium heat. Stir in cream cheese until melted and combined with the beef. Slowly pour in heavy cream, stirring constantly. Once warm, add shredded mozzarella and grated Parmesan, stirring until everything melts into a creamy sauce.

Step 4: Combine Pasta and Sauce

Add the cooked spaghetti to the skillet, tossing gently to coat in the creamy sauce. If it’s too thick, add a splash of reserved pasta water until it reaches your desired consistency.

Step 5: Serve

Serve hot, topped with extra Parmesan or fresh herbs if desired. The sauce will cling beautifully to every strand of pasta, delivering a creamy, Cajun-spiced bite in every forkful.

Watch Out for These Mistakes While Cooking

When making Cajun Beef Spaghetti in Creamy Three-Cheese Parmesan Sauce, it’s easy to slip into common cooking missteps. One big mistake is overcooking the spaghetti—aim for al dente to avoid a mushy texture when it absorbs the sauce. Another is not draining the beef properly if it releases too much grease; you want richness, not an oily mess. Also, don’t rush the cheese melting process. Let it melt gradually over low heat for that smooth, creamy finish instead of a clumpy sauce.

Be cautious with the Cajun seasoning—its intensity varies by brand. Start with a moderate amount, taste, and adjust as needed so you don’t overpower the other flavors. Lastly, use freshly grated Parmesan. Pre-shredded cheese often contains anti-caking agents that affect how it melts.

How to Serve and Store Cajun Beef Spaghetti in Creamy Three-Cheese Parmesan Sauce

This recipe serves about four people generously, making it perfect for family dinners or meal prepping. Serve it hot from the skillet, optionally garnished with chopped parsley, extra Parmesan, or even a sprinkle of red pepper flakes if you’re feeling bold.

Leftovers can be stored in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stove or in the microwave, adding a splash of cream or milk to bring back the sauce’s creaminess. This dish doesn’t freeze well due to the dairy content, which can separate upon thawing.
