Method
 

Step 1: Bring a pot of salted water to a boil and cook the pasta shells according to package instructions. Reserve 1/4 cup of pasta water, then drain and set aside.
    Step 2: While the pasta cooks, season the steak cubes with Cajun seasoning, black pepper, paprika, and a pinch of salt. Toss well to coat evenly.
      Step 3: Heat olive oil in a large skillet over medium-high heat. Add the steak bites in a single layer and sear for 2–3 minutes per side until browned and cooked to your preferred doneness.
        Step 4: Remove the steak from the skillet and set aside to rest.
          Step 5: In the same skillet, melt the butter over medium heat. Add minced garlic and sauté for about 1 minute until fragrant.
            Step 6: Pour in the heavy cream and stir gently. Let it simmer for 2–3 minutes until slightly thickened.
              Step 7: Add the cheddar cheese and Parmesan cheese. Stir continuously until the cheese is fully melted and the sauce becomes smooth.
                Step 8: Add the cooked pasta shells to the skillet and toss to coat them in the creamy garlic cheese sauce. Add reserved pasta water if needed to loosen the sauce.
                  Step 9: Return the steak bites to the skillet and gently mix everything together.
                    Step 10: Taste and adjust seasoning with salt and pepper if needed.
                      Step 11: Garnish with fresh parsley and serve immediately.

                        1. What cut of steak is best for this recipe?
                        Sirloin or ribeye works best because they are tender and flavorful.
                        2. Can I cook the steak well-done?
                        Yes, but for best tenderness, cook it medium to medium-high.
                        3. Can I use store-bought Cajun seasoning?
                        Yes, it works perfectly and saves time.
                        4. How do I keep the steak juicy?
