How To Make the Cajun Beef Spaghetti in Creamy Three-Cheese Parmesan Sauce

Step 1: Brown the Beef

Heat olive oil in a large skillet over medium heat. Add the ground beef, season with salt and pepper, and cook until browned. Drain excess fat if necessary.

Step 2: Add Flavor Base

Add minced garlic to the beef and cook for 1 minute until fragrant. Stir in Cajun seasoning and let it bloom in the heat.

Step 3: Cook the Pasta

In a separate large pot, cook spaghetti according to package directions until al dente. Reserve 1 cup of pasta water, then drain.

Step 4: Make the Sauce

Lower the skillet heat and add butter, followed by heavy cream. Stir until the butter melts and the mixture is smooth.

Step 5: Add the Cheeses

Gradually add Parmesan, mozzarella, and cheddar, stirring until the sauce is creamy. If the sauce is too thick, add a splash of reserved pasta water.

Step 6: Combine and Garnish

Add the cooked spaghetti to the sauce and toss until fully coated. Garnish with chopped parsley and serve hot.

Serving & Storing Cajun Beef Spaghetti

Serve this pasta immediately while the cheese sauce is at its creamiest. It pairs beautifully with garlic bread, a fresh green salad, or roasted vegetables. For storage, keep leftovers in an airtight container in the fridge for up to 3 days. Reheat gently with a splash of cream or milk to restore its velvety texture.
