Step‑by‑Step Instructions for Cajun Beef Spaghetti
Step 1: Boil Pasta
Bring a large pot of salted water to a rolling boil. Add your spaghetti and cook according to package instructions until al dente, usually around 8-10 minutes. Once cooked, drain the pasta in a colander and drizzle a little olive oil to prevent sticking. Set aside while you prepare the sauce.
Step 2: Sauté Aromatics
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the chopped onion and sauté for about 3 minutes, stirring frequently until it becomes translucent. Next, toss in the minced garlic and continue cooking for an additional 30 seconds, until fragrant but not browned. This aromatic base will elevate your Cajun Beef Spaghetti!
Step 3: Brown the Beef
Add the ground beef to the skillet, breaking it apart with a spatula. Cook for 5-7 minutes until the meat is browned throughout. Make sure to stir frequently and drain any excess fat to keep your dish lighter. The browning process adds a delicious depth of flavor that perfectly complements the spicy seasoning.
Step 4: Season the Meat
Sprinkle the Cajun seasoning, smoked paprika, crushed red pepper flakes, salt, and pepper over the browned beef. Stir well and cook for an additional 1-2 minutes, allowing the flavors to meld and intensify. Your Cajun Beef Spaghetti is already starting to smell amazing as those spices infuse the meat!
Step 5: Add Sauce
Pour in the tomato sauce and beef broth, stirring to combine all the ingredients thoroughly. Raise the heat slightly and allow the mixture to come to a gentle simmer. Cover and let it simmer for about 5-7 minutes, so the flavors can deepen. You’ll see the sauce thicken slightly and become a vibrant red.
Step 6: Combine Pasta
Once the sauce has simmered, gently stir in the cooked spaghetti, ensuring every strand is well-coated with the rich sauce. Use tongs to toss the pasta evenly, distributing the delicious beef and Cajun flavor throughout. This is where your Cajun Beef Spaghetti transforms into a hearty, flavorful main dish.
Step 7: Serve
Divide your flavorful Cajun Beef Spaghetti among serving plates. Garnish generously with freshly chopped parsley and a sprinkle of grated Parmesan on top. Serve immediately while hot and enjoy the delightful combination of spice and comfort in every bite!

Make Ahead Options
These Cajun Beef Spaghetti are perfect for meal prep enthusiasts! You can prepare the sauce up to 3 days in advance. Simply follow the recipe through to Step 5, then transfer the cooled sauce to an airtight container and refrigerate. This allows the flavors to deepen, making the sauce even more delicious! For the pasta, cook it just until al dente, and store separately in the fridge for up to 2 days. When you're ready to serve, reheat the sauce on the stovetop and cook the pasta for an additional minute in boiling water. Toss together and garnish as usual for a quick weeknight meal that is just as flavorful as if made fresh!
