Season the NY strip steaks with salt, pepper, and thyme or rosemary.

In a skillet, heat avocado oil over medium-high heat and sear the steaks for about 4-5 minutes on each side.

Remove the steaks from the skillet and let them rest.

In the same skillet, add butter and sauté the diced onion and red bell pepper until softened.

Add minced garlic and cook for an additional minute.

Stir in the tomato paste, heavy cream, and bring to a simmer.

Add the cooked rigatoni pasta, Parmesan cheese, red pepper flakes, Cajun seasoning, garlic powder, oregano, cayenne powder, salt, and pepper.

Toss everything together until well combined and heated through.

Slice the rested steaks and serve on top of the creamy pasta.
