Ingredients

• 12 oz spaghetti
• 1½ lbs ground beef
• 1 small onion, finely diced
• 1 green bell pepper, diced
• 1 red bell pepper, diced
• 5 tablespoons butter, divided
• 2 tablespoons olive oil
• 6 cloves garlic, minced
• 2 tablespoons Cajun seasoning, divided
• 1 teaspoon smoked paprika
• 1½ cups heavy cream
• 1 cup beef broth
• 4 oz cream cheese, softened
• 1 cup freshly grated Parmesan cheese
• 1½ cups shredded mozzarella cheese
• ½ cup shredded cheddar cheese
• 1 teaspoon salt
• ½ teaspoon freshly ground black pepper
• ¼ teaspoon red pepper flakes
• 2 tablespoons fresh parsley, chopped

Instructions

1. Cook the spaghetti:
   Bring a large pot of salted water to a boil. Cook the spaghetti according to package directions until al dente. Drain and set aside.
2. Brown the beef:
   Heat the olive oil and 2 tablespoons of butter in a large deep skillet over medium-high heat. Add the ground beef and cook, breaking it into bite-sized pieces, until nicely browned. Drain excess grease if necessary.
3. Cook the vegetables:
   Add the diced onion, green bell pepper and red bell pepper to the beef. Cook for about 4–5 minutes, stirring occasionally, until the vegetables begin to soften.
4. Add the seasonings:
   Stir in the minced garlic, Cajun seasoning, smoked paprika, salt, black pepper and red pepper flakes. Cook for about 1 minute until fragrant.
5. Start the cream sauce:
   Reduce the heat to medium-low. Add the remaining 3 tablespoons of butter, heavy cream and beef broth. Stir well and bring the mixture to a gentle simmer.
6. Add the cream cheese:
   Stir in the softened cream cheese until it melts completely and the sauce becomes smooth.
7. Make it three-cheese:
   Gradually add the Parmesan, mozzarella and cheddar cheese. Stir over low heat until all three cheeses are melted and the sauce is creamy and smooth. Avoid boiling the sauce after adding the cheese.
8. Combine:
   Add the cooked spaghetti directly to the skillet. Toss gently until every strand of pasta is coated with the creamy Cajun beef sauce.
9. Finish and serve:
   Taste and adjust the seasoning if needed. Sprinkle with freshly chopped parsley and serve immediately while hot and creamy.

Tips for the Best Creamy Cajun Spaghetti

• Cook the spaghetti only until al dente so it stays firm when mixed with the hot sauce.
• Freshly grated cheese melts more smoothly than pre-shredded cheese.
• Keep the heat low when adding the cheese to prevent the sauce from becoming grainy.
• If the sauce becomes too thick, stir in a splash of beef broth or cream.
• Different Cajun seasoning blends vary in salt and heat, so adjust the added salt to taste.
• For extra heat, increase the red pepper flakes slightly.

What to Serve With Cajun Beef Spaghetti

This creamy pasta is hearty enough to serve as a complete meal, but it pairs especially well with garlic bread, a simple green salad, roasted vegetables or steamed broccoli. A crisp salad is particularly good for balancing the richness of the cheese sauce.

Storage and Reheating

Place leftovers in an airtight container and refrigerate for up to 3 days. The sauce will thicken as it chills. When reheating, add a small splash of milk, cream or beef broth and warm gently over low heat, stirring occasionally until creamy again.

Frequently Asked Questions

Can I make this pasta less spicy?

Yes. Leave out the red pepper flakes and use a mild Cajun seasoning. You can also start with less Cajun seasoning and add more after tasting the sauce.

Can I use another type of pasta?

Absolutely. Linguine, fettuccine, penne or rigatoni can all be used instead of spaghetti.

Why is my cheese sauce too thick?

The cheese naturally thickens the sauce, especially as it cools. Stir in a little warm beef broth, heavy cream or milk until it reaches your preferred consistency.

Can I prepare it ahead?

The dish is best served freshly made because the sauce is creamiest immediately after cooking. However, the beef and vegetable mixture can be prepared ahead, refrigerated and reheated before finishing the cream sauce and pasta.
