Ingredients You’ll Need

For the Pasta and Beef:

12 oz spaghetti
1½ lbs ground beef
2 tablespoons olive oil
1 tablespoon Cajun seasoning
1 teaspoon smoked paprika
½ teaspoon onion powder
½ teaspoon garlic powder
Salt & pepper to taste
4 cloves garlic, minced

For the Sauce:

1 cup heavy cream
¾ cup grated Parmesan cheese
1 cup shredded cheddar or mozzarella cheese
½ cup reserved pasta water (if needed to thin the sauce)

For Garnish:

Fresh parsley or green onions

Preparation

Step 1: Bring a large pot of salted water to a boil. Add the spaghetti and cook until al dente according to the package directions. Before draining, reserve about ½ cup of the starchy pasta water. Drain the rest and set the pasta aside.

Step 2: While the pasta cooks, heat the olive oil in a large skillet over medium heat. Add the ground beef and cook, breaking it up as it browns, for about 6–8 minutes. Once fully browned, season it with Cajun seasoning, smoked paprika, onion powder, garlic powder, salt, and pepper.

Step 3: Add the minced garlic to the beef and sauté for another minute until it becomes fragrant. The spices and garlic together should be rich and aromatic at this point.

Step 4: Lower the heat and stir in the heavy cream. Once it starts to simmer gently, add in the Parmesan and cheddar or mozzarella. Stir constantly until the cheese melts and the sauce becomes smooth and creamy.

Step 5: Add the cooked spaghetti directly into the skillet and toss it well with the sauce. If the sauce seems too thick, add a splash of that reserved pasta water to loosen things up. Keep tossing until the pasta is evenly coated.

Step 6: Garnish with freshly chopped parsley or sliced green onions and serve warm.

Variation Ideas

Cajun Beef Spaghetti in Creamy Three-Cheese Parmesan Sauce

Even though this dish is incredibly satisfying as is, you can easily adapt it to suit different preferences, dietary needs, or just whatever’s in your fridge. Here are a few creative ideas to make this Cajun beef spaghetti your own:

Swap the Meat: If you’re not into beef or want to lighten it up, try using ground turkey, chicken, or even crumbled Italian sausage. For a vegetarian version, replace the beef with sautéed mushrooms or a plant-based meat alternative.
Go Gluten-Free: Swap out the traditional spaghetti for your favorite gluten-free pasta. Many brands now offer great-tasting alternatives made from rice, quinoa, or chickpeas.
Cheese Choices: While this version uses cheddar or mozzarella and Parmesan, feel free to mix in other cheeses like Monterey Jack, Fontina, or a creamy Gouda for a deeper flavor.
Add Veggies: Toss in spinach, kale, or chopped zucchini during the final few minutes of cooking for an extra dose of greens. Bell peppers and roasted red peppers also work beautifully with the Cajun seasoning.
Spice Control: If you’re cooking for kids or spice-sensitive guests, reduce the Cajun seasoning by half or skip the smoked paprika. You can always offer red pepper flakes at the table for those who like a kick.

These small changes keep the dish exciting every time you make it.

How to Serve

This creamy Cajun spaghetti can hold its own as a one-bowl wonder, but pairing it with a few extras really rounds out the meal. Here are some easy serving ideas:

Sides: A crisp green salad with a tangy vinaigrette helps balance the richness of the sauce. Garlic bread or a warm baguette on the side is perfect for scooping up the extra cheese sauce.
Vegetable Pairings: Roasted or sautéed vegetables like broccoli, green beans, or Brussels sprouts make a hearty companion. You can also serve it alongside grilled asparagus or a medley of bell peppers for extra color and nutrients.
Toppings: Offer a small dish of crushed red pepper flakes for heat lovers, or an extra sprinkle of grated Parmesan and chopped parsley at the table.
Beverage Pairing: Stick with iced tea, lemonade, or sparkling water for a casual vibe.

Whether you’re making it for date night or a family dinner, this dish feels indulgent and cozy every single time.

Recipe Tips

Here are a few helpful tips to make your Cajun beef spaghetti experience even smoother and more delicious:

Don’t Overcook the Pasta: Boil your spaghetti just to al dente so it can soak up the sauce without turning mushy.
Use High-Quality Cheese: Pre-shredded cheeses are convenient but often contain anti-caking agents that don’t melt as smoothly. Freshly grated cheese will give your sauce the best texture.
Reserve Pasta Water: The starchy water from boiling the pasta helps emulsify the sauce, making it silkier. It’s your secret weapon if the sauce turns out too thick.
Make It Ahead: You can cook the beef and prepare the sauce a day ahead. Just reheat slowly on the stovetop and add the cooked pasta when ready to serve.
Double Up: This recipe is easily doubled to feed a crowd or prep for leftovers. Just make sure your skillet or pot is large enough.
Freeze Leftovers: Store any leftovers in an airtight container in the fridge for up to 3 days or freeze them for up to a month.

Taking a little extra care during each step ensures a pasta dish that tastes as good as anything from your favorite restaurant.

Cooking Note

To help you avoid common pitfalls and make your cooking experience even better, here are a few quick bullet points:

Avoid overcooking the garlic, as it becomes bitter quickly. Keep the heat moderate.
If the sauce is too thick after adding the cheese, gradually stir in reserved pasta water until it reaches your desired consistency.
Let the beef brown properly before stirring it builds more flavor.
Season the pasta water with salt like the sea. It’s your first chance to flavor the noodles.
Don’t skip the fresh herbs, they add brightness and a touch of freshness that balances the richness of the cheese.
