Why You’ll Love This Cajun Ground Beef Spaghetti
There is so much to love about this creamy Cajun pasta. The ground beef is first browned until it develops dark, crispy edges, giving the dish a deep savory flavor that you simply cannot get from lightly cooked beef.
The sauce is just as important. Beef broth, heavy cream, cream cheese, Parmesan, mozzarella, and sharp cheddar come together to create a rich, smooth sauce with plenty of cheesy flavor. Cajun seasoning and smoked paprika add warmth and depth without overpowering the dish.
Another advantage is how easily everything comes together in one skillet after the spaghetti is cooked. The pasta water helps loosen the sauce while adding starch, allowing the sauce to cling beautifully to every strand.
Ingredients You’ll Need
For the Pasta
- 1 lb spaghetti
- 1 tablespoon salt, for the pasta water
- 1 cup reserved pasta water
Cook the spaghetti just until slightly firm. Finishing it in the sauce allows the pasta to absorb even more flavor.
For the Cajun Ground Beef
- 1½ lbs 80/20 ground beef
- 2 tablespoons unsalted butter, divided as directed
- 6 garlic cloves, minced
- 2 tablespoons Cajun seasoning, divided
- 2 teaspoons smoked paprika, divided
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- ½ teaspoon black pepper
- ½ teaspoon salt
Using 80/20 ground beef provides enough fat to create excellent browning and keeps the meat flavorful and juicy.
For the Three-Cheese Parmesan Sauce
- ½ cup beef broth
- 1½ cups heavy cream
- 4 oz cream cheese, softened and cubed
- 1 cup freshly grated Parmesan, divided
- 1½ cups low-moisture shredded mozzarella, divided
- 1 cup shredded sharp cheddar, divided
- 1½ teaspoons Italian seasoning, divided
Freshly grated cheese melts more smoothly and gives the sauce a better texture than many pre-shredded varieties.
How to Make Creamy Cajun Ground Beef Spaghetti
1. Cook the Spaghetti
Bring a large pot of water to a rolling boil. Add 1 tablespoon of salt and cook the spaghetti for about 1 minute less than the package instructions recommend.
The pasta should remain slightly firm because it will finish cooking in the creamy sauce.
Before draining, reserve 1 cup of pasta water. Drain the spaghetti without rinsing it.
2. Brown the Ground Beef
While the pasta cooks, heat a large deep skillet over medium-high heat.
Add the ground beef in a single layer and press it gently into the pan. Let it cook undisturbed for 3 to 4 minutes.
This step allows the beef to develop a deep, caramelized crust before you break it apart.
Once browned underneath, break the beef into smaller crumbles.
Add:
- 1 tablespoon Cajun seasoning
- 1 teaspoon smoked paprika
- Garlic powder
- Onion powder
- ½ teaspoon salt
- Black pepper
Continue cooking for another 5 to 6 minutes, stirring occasionally, until the beef is deeply browned and develops crispy edges.
3. Add the Garlic Butter
Spoon off all but approximately 1 tablespoon of the rendered beef fat.
Push the beef toward one side of the skillet. Add 2 tablespoons of butter and the minced garlic to the empty side.
Cook the garlic for 30 to 45 seconds, stirring constantly. It should become fragrant without turning brown.
Mix the garlic butter into the beef, then transfer the beef mixture to a bowl and set aside.
4. Build the Cajun Cream Sauce
Reduce the skillet heat to medium.
Add the remaining 2 tablespoons of butter. Stir in the remaining Cajun seasoning, remaining smoked paprika, and 1 teaspoon Italian seasoning.
Allow the spices to bloom in the butter for about 30 seconds. The butter should become fragrant and take on a beautiful reddish-orange color.
Pour in the beef broth and immediately scrape the bottom of the skillet with a wooden spoon or spatula.
Those browned bits contain a tremendous amount of flavor.
Let the broth simmer for about 1 minute.
5. Add the Cream and Cream Cheese
Reduce the heat to medium-low and slowly pour in the heavy cream.
Simmer gently for 3 to 4 minutes, stirring frequently, until the sauce begins to thicken slightly and coats the back of a spoon.
Avoid bringing the cream to a hard boil.
Add the softened cream cheese cubes and whisk for about 2 minutes, until completely melted and the sauce becomes smooth and creamy.
6. Melt in the Three Cheeses
Remove the skillet from the heat and allow the bubbling to stop for about 1 minute.
Gradually whisk in:
- ¾ cup Parmesan
- ¾ cup shredded cheddar
- 1 cup mozzarella
Add the cheese a handful at a time, allowing each addition to melt before adding more.
The finished sauce should be thick, smooth, velvety, and lightly orange from the Cajun seasoning and smoked paprika.
7. Combine the Pasta and Beef
Return the skillet to low heat.
Add the cooked spaghetti and browned ground beef to the cheese sauce.
Use tongs to toss everything together until every strand of spaghetti is coated.
Gradually add the reserved pasta water, a splash at a time, tossing continuously.
Stop when the sauce becomes glossy and coats the pasta beautifully.
Do not worry if the sauce appears slightly loose at this stage. It will naturally thicken as the pasta rests.
8. Finish with More Cheese
Sprinkle the remaining:
- ½ cup mozzarella
- ¼ cup cheddar
- ¼ cup Parmesan
over the pasta.
Cover the skillet and cook over low heat for 1 to 2 minutes, just until the cheese melts into gooey, stretchy patches.
Remove from the heat.
Finish with the remaining ½ teaspoon Italian seasoning and a light sprinkle of Cajun seasoning and smoked paprika.
Let the pasta rest for about 2 minutes before serving.
Tips for the Best Cajun Ground Beef Spaghetti
Brown the Beef Properly
Avoid stirring the ground beef immediately after adding it to the skillet. Giving it several minutes of undisturbed contact with the hot pan creates the caramelized crust that gives this recipe its rich flavor.
Use Freshly Grated Cheese
Freshly grated Parmesan, mozzarella, and cheddar generally melt more smoothly into the sauce. They also provide a richer, more natural cheese flavor.
Don’t Boil the Cream Sauce
A gentle simmer is all you need. Excessive heat can cause the cream and cheese to separate, resulting in a greasy or grainy sauce.
Reserve Enough Pasta Water
Pasta water is one of the secrets to achieving a silky sauce. The starch helps emulsify the sauce and allows you to adjust the consistency without making it watery.
Add Cheese Gradually
Adding all the cheese at once can make it harder for the sauce to remain smooth. A handful at a time gives each cheese enough time to melt properly.
How Spicy Is This Cajun Pasta?
This recipe has a noticeable Cajun flavor with smoky, savory warmth. The exact heat level depends on the Cajun seasoning you use.
For a milder version, use a mild Cajun blend and reduce the amount slightly.
For extra heat, add a pinch of crushed red pepper flakes or a little cayenne pepper to the sauce.
Easy Variations
Add Bell Peppers
For extra color and sweetness, sauté diced red, yellow, or green bell peppers with the ground beef.
Add Spinach
A few handfuls of baby spinach can be stirred into the sauce just before adding the pasta. The residual heat will wilt it quickly.
Use Ground Turkey
Ground turkey can replace the beef for a lighter variation. Because turkey is leaner, add a little extra butter or olive oil when browning.
Add More Vegetables
Mushrooms, zucchini, onions, or broccoli can all work well with the Cajun cheese sauce.
Make It Extra Cheesy
If you love an especially rich cheese pull, add a little extra mozzarella over the top before covering the skillet.
What to Serve with Cajun Ground Beef Spaghetti
This pasta is rich and filling, so simple sides work best.
Try serving it with:
- Crisp green salad
- Steamed broccoli
- Roasted vegetables
- Garlic bread
- Toasted French bread
- Simple cucumber salad
A fresh salad with a light vinaigrette is particularly good because its acidity balances the richness of the creamy cheese sauce.
How to Store Leftovers
Allow the pasta to cool slightly before transferring it to an airtight container.
Refrigerate for up to 3 days.
Because the sauce contains several cheeses, it will become thicker when chilled. When reheating, add a small splash of milk, cream, beef broth, or water and warm gently over low to medium heat.
Stir frequently until the sauce becomes creamy again.
For the best texture, avoid overheating the pasta.
Frequently Asked Questions
Can I make this recipe ahead of time?
Yes. You can prepare the beef and sauce ahead of time and refrigerate them separately. Cook the spaghetti when you are ready to serve, then combine everything in the skillet and warm gently.
Can I use another type of pasta?
Absolutely. Penne, rigatoni, fettuccine, linguine, rotini, or bow-tie pasta can all work well. Choose a shape that can hold plenty of the creamy sauce.
Why is my cheese sauce too thick?
The most common reason is not adding enough pasta water. Add a small splash at a time while tossing the pasta until the sauce reaches a glossy, creamy consistency.
Why did my cheese sauce become grainy?
The heat may have been too high when the cheese was added. Remove the skillet from the heat before incorporating the cheese and add it gradually.
Can I make this less rich?
Yes. You can replace part of the heavy cream with whole milk. Keep in mind that the sauce will be slightly lighter and less luxurious.
Can I freeze this pasta?
Cream-based cheese sauces can change texture after freezing and thawing, so freezing is not recommended for the best results. Refrigerating leftovers for a few days gives a much better texture.

Ingredients
Method
- Bring a large pot of water to a boil and add 1 tbsp salt. Cook the spaghetti 1 minute short of the package time so it stays slightly firm. Reserve 1 cup of the pasta water, drain, and do not rinse.
- While the pasta cooks, heat a large, deep skillet over medium-high heat. Add the ground beef in one layer and press it flat. Leave it undisturbed for 3 to 4 minutes so it builds a dark, caramelized crust.
- Break the beef into crumbles and season with 1 tbsp Cajun seasoning, 1 tsp smoked paprika, the garlic powder, onion powder, ½ tsp salt, and the black pepper. Cook 5 to 6 more minutes, until deeply browned with dark crispy edges.
- Spoon off all but 1 tbsp of the fat. Push the beef to one side, add 2 tbsp butter and the garlic, and stir the garlic in the butter for 30 to 45 seconds, until fragrant but not browned. Stir it into the beef, then transfer everything to a bowl.
- Reduce the heat to medium and add the remaining 2 tbsp butter to the same pan. Stir in the remaining 1 tbsp Cajun seasoning, the remaining 1 tsp smoked paprika, and 1 tsp Italian seasoning. Let the spices bloom for 30 seconds so the butter turns reddish-orange.
- Pour in the beef broth and scrape up all the browned bits from the bottom of the pan. Simmer 1 minute.
- Reduce the heat to medium-low and pour in the heavy cream. Simmer gently for 3 to 4 minutes, stirring often, until it thickens slightly and coats the back of a spoon. Do not let it boil hard.
- Add the cream cheese cubes and whisk for 2 minutes, until completely melted and smooth.
- Take the pan off the heat and let the bubbling stop for 1 minute. Whisk in ¾ cup Parmesan, ¾ cup cheddar, and 1 cup mozzarella a handful at a time, waiting until each addition melts before adding the next. The sauce should be thick, velvety, and pale orange.
- Return the pan to low heat. Add the spaghetti and the beef, and toss with tongs until every strand is coated. Loosen with the reserved pasta water, a splash at a time, until the sauce turns glossy and clings to the pasta. It will thicken as it sits.
- Sprinkle the remaining ½ cup mozzarella, ¼ cup cheddar, and ¼ cup Parmesan over the top. Cover and cook on low for 1 to 2 minutes, until the cheese melts into gooey, stretchy patches.
- Finish with the remaining ½ tsp Italian seasoning and a light dusting of Cajun seasoning and smoked paprika. Rest 2 minutes, then serve immediately in large bowls, piled high, with the creamy sauce pooling at the base.
