Step‑by‑Step Instructions for Cajun Beef Spaghetti
Step 1: Cook the Spaghetti
Begin by bringing a large pot of salted water to a rolling boil. Add in 8 ounces of spaghetti, stirring occasionally to prevent sticking, and cook according to package instructions until al dente—usually around 8-10 minutes. Once done, drain the spaghetti, reserving a cup of pasta water, and set it aside while you prepare the sauce.
Step 2: Sear the Beef
While the spaghetti cooks, take 1 pound of diced sirloin or ribeye steak and season it generously with Cajun seasoning. Heat a large skillet over medium-high heat, adding 2 tablespoons of butter. Once melted and bubbling, add the seasoned beef, searing it for about 3-4 minutes until browned and caramelized. Remove the beef from the skillet and set it aside on a plate.
Step 3: Sauté the Garlic
In the same skillet, reduce the heat to medium and add 1 tablespoon of minced garlic, sautéing for about 1 minute until fragrant, stirring constantly to prevent burning. The heavenly aroma will fill your kitchen, signaling that it’s time to add the creamy sauce ingredients. Be sure to scrape any browned bits from the bottom of the skillet for extra flavor.
Step 4: Prepare the Creamy Sauce
Pour in 1 cup of heavy cream into the skillet with the sautéed garlic, stirring gently to combine. Add 4 ounces of cream cheese, 1 cup of shredded mozzarella, and ½ cup of grated Parmesan cheese, stirring continuously over medium heat. Allow the cheeses to melt and the sauce to become smooth and creamy, which should take about 3-4 minutes.
Step 5: Combine Pasta and Beef
Once your sauce is velvety smooth, add the cooked spaghetti and the previously seared beef back into the skillet. Toss everything together until the pasta and beef are well-coated in the creamy sauce. If the mixture seems too thick, gradually add some reserved pasta water until the desired consistency is reached, ensuring each strand of spaghetti is enveloped in flavor.
Step 6: Garnish and Serve
Remove the skillet from the heat and sprinkle chopped fresh parsley over the Cajun Beef Spaghetti for a burst of color and flavor. Serve the dish hot, with additional cheese and Cajun seasoning on the side for those who want a little extra kick. Enjoy your comforting meal that combines creamy, cheesy goodness with bold Cajun flair!
