Ingredients

For the Pasta and Beef

12 oz (340g) spaghetti
1½ lbs (680g) ground beef
2 tablespoons olive oil
1 tablespoon Cajun seasoning
1 teaspoon smoked paprika
½ teaspoon onion powder
½ teaspoon garlic powder
Salt, to taste
Black pepper, to taste
4 cloves garlic, minced

For the Creamy Three-Cheese Sauce

1 cup (240ml) heavy cream
¾ cup (75g) grated Parmesan cheese
1 cup (110g) shredded cheddar cheese or mozzarella cheese
½ cup reserved pasta water (if needed)

For Garnish

Fresh chopped parsley
Sliced green onions (optional)

Instructions

Step 1: Cook the Spaghetti

Bring a large pot of salted water to a boil.

Cook the spaghetti according to the package directions until al dente.

Before draining, reserve ½ cup of the pasta cooking water.

Drain the pasta and set it aside.

Step 2: Brown the Beef

Heat the olive oil in a large skillet over medium heat.

Add the ground beef and cook for 6–8 minutes, breaking it apart as it browns.

Season with the Cajun seasoning, smoked paprika, onion powder, garlic powder, salt, and black pepper.

Step 3: Add the Garlic

Stir in the minced garlic and cook for about 1 minute until fragrant.

Step 4: Make the Creamy Cheese Sauce

Reduce the heat to medium-low.

Pour in the heavy cream and bring it to a gentle simmer.

Add the Parmesan cheese and shredded cheddar (or mozzarella), stirring constantly until the cheeses melt completely and the sauce becomes smooth and creamy.

If the sauce is too thick, gradually stir in some of the reserved pasta water until it reaches your desired consistency.

Step 5: Combine Everything

Add the cooked spaghetti to the skillet.

Toss well until every strand is coated in the rich Cajun cheese sauce.

Continue tossing for 1–2 minutes so the pasta absorbs the flavors.

Step 6: Garnish and Serve

Sprinkle with freshly chopped parsley or sliced green onions.

Serve immediately while hot with extra Parmesan cheese if desired.

Tips for the Best Cajun Beef Spaghetti

Reserve the pasta water before draining—it helps create an extra silky sauce.
Freshly grate the Parmesan for the smoothest texture.
Cook the garlic only until fragrant to avoid bitterness.
Add extra Cajun seasoning if you enjoy spicier pasta.
Stir the cheese into the cream over low heat to prevent the sauce from separating.

Delicious Variations

Add Vegetables

Mix in sautéed mushrooms, spinach, bell peppers, or broccoli for extra flavor and nutrition.

Make It Extra Cheesy

Add ½ cup shredded Monterey Jack, Colby Jack, or Pepper Jack cheese for an even richer sauce.

Add Heat

Stir in crushed red pepper flakes or diced jalapeños for extra spice.

Try Another Protein

Replace the ground beef with ground turkey, ground chicken, Italian sausage, or sliced steak.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days.

Reheat gently over low heat with a splash of milk or heavy cream to restore the creamy texture.
