1. Pat the steak dry and coat with olive oil, Cajun seasoning, smoked paprika, salt, and pepper. Let sit at room temperature for 20–30 minutes.

2. Cook rotini pasta in salted water until al dente. Reserve ½ cup pasta water, then drain and set aside.

3. Heat a skillet on medium-high. Sear the steak 3–4 minutes per side, then remove and let rest for 5 minutes.

4. In the same pan, reduce heat and melt butter. Add garlic and sauté for 30–60 seconds.

5. Pour in the cream and let simmer for 2–3 minutes.

6. Stir in parmesan cheese, Italian seasoning, red pepper flakes, salt, and pepper. Whisk until smooth.

7. Add pasta to the sauce. Toss to coat. Use pasta water to loosen if needed.

8. Slice rested steak and serve over or beside the pasta. Garnish with parsley and a squeeze of lemon.
