Why You’ll Love This Creamy Cajun Beef Spaghetti

This pasta recipe ticks all the boxes: it’s quick enough for busy nights, indulgent enough for special occasions, and absolutely packed with comforting, rich flavors. The beef is browned until perfectly caramelized, then simmered in a Cajun-spiced sauce that clings to each strand of spaghetti. Paired with a trio of cheeses, it turns into a creamy, soul-satisfying meal that even picky eaters can’t turn down.

Plus, you can easily adjust the spice level, making it family-friendly or fiery-hot depending on your preference. It’s also an excellent dish to prepare ahead of time or even reheat the next day—somehow, it tastes even better then!

What Kind of Spaghetti Should I Use?

For the ultimate texture and flavor experience, opt for thick-cut spaghetti or bucatini. Their firm bite and hollow centers trap the creamy cheese sauce beautifully. However, you can use whatever pasta you have on hand—fettuccine, linguine, or even penne will all work well with the rich Cajun beef sauce. Just be sure to cook it al dente, as it will continue to absorb the sauce once mixed.

Ingredients for the Creamy Cajun Beef Spaghetti

Every ingredient in this dish plays a flavorful role. From the bold spices to the creamy cheese blend, here’s what you need to make it a standout meal:

• Spaghetti or Bucatini – The base of the dish that soaks up all that luscious cheese sauce.
• Ground Beef – Adds rich, hearty protein and absorbs the Cajun spice blend beautifully.
• Heavy Cream – Essential for creating a silky, creamy base that ties everything together.
• Cream Cheese – Adds body and a slightly tangy richness to the sauce.
• Parmesan, Mozzarella & Cheddar Cheese – This trio melts into a gooey, flavorful layer that clings to the pasta.
• Cajun Seasoning – The hero spice blend that delivers that signature smoky, spicy kick.
• Garlic & Onion – Builds flavor depth and adds savory aromatic notes.
• Chili Flakes – Optional, but perfect for adding an extra punch of heat.
• Fresh Parsley – For brightness and color in every bite.
• Olive Oil or Butter – Used for cooking down the beef and aromatics.

How To Make the Creamy Cajun Beef Spaghetti

Step 1: Brown the Beef with Flavor

Heat a skillet over medium-high heat and add olive oil or butter. Add the ground beef and cook until browned and caramelized. Stir in chopped onion and minced garlic, cooking until fragrant. Sprinkle in Cajun seasoning and stir well to coat the meat.

Step 2: Cook the Pasta

In a large pot, bring salted water to a boil and cook your spaghetti or bucatini until al dente. Reserve a bit of the pasta water before draining.

Step 3: Build the Creamy Cheese Sauce

In the same pan with the beef, lower the heat and add heavy cream and cream cheese. Stir until smooth. Mix in grated parmesan, mozzarella, and cheddar. Let it melt slowly, stirring until the sauce becomes rich and creamy.

Step 4: Combine Everything

Add the cooked pasta to the sauce, tossing well to coat every strand. If the sauce feels too thick, use reserved pasta water to loosen it up. Simmer for a minute or two to marry the flavors.

Step 5: Garnish and Serve

Top with a sprinkle of chili flakes and freshly chopped parsley. Serve hot, straight from the skillet for a rustic, hearty meal.
