01 - Bring a large pot of salted water to a boil. Cook the tortellini according to package instructions. Drain and set aside.
02 - While the pasta cooks, season the steak cubes evenly with salt and pepper on all sides.
03 - Heat a large skillet over medium-high heat. Add 1 tablespoon butter and sear the steak cubes for 2-3 minutes per side until browned and cooked to desired doneness. Remove steak from the skillet and set aside.
04 - In the same skillet, reduce heat to medium. Add the remaining 1 tablespoon butter and the minced garlic. Sauté for 1 minute until fragrant, being careful not to burn the garlic.
05 - Pour in the heavy cream, stirring to deglaze the pan and incorporate any browned bits. Add Parmesan cheese, Italian herbs, red pepper flakes, and a pinch of salt and pepper. Simmer for 2-3 minutes until slightly thickened.
06 - Add the cooked tortellini and steak back to the skillet. Toss gently to coat everything evenly in the sauce and heat through for 1-2 minutes. Remove from heat, garnish with chopped parsley and extra Parmesan. Serve immediately.
