01 - Bring a large pot of salted water to a boil. Cook penne according to package instructions until al dente. In the last 2 minutes of cooking, add broccoli florets. Drain and set aside.
02 - Season steak strips with salt and pepper. Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add steak and sear for 2–3 minutes per side until just cooked through. Remove steak to a plate and cover loosely.
03 - In the same skillet, add remaining olive oil. Add minced garlic and cook until fragrant, about 1 minute.
04 - Stir in cherry tomatoes and cook for 2–3 minutes until just softened.
05 - Lower heat to medium. Pour in the heavy cream, stirring to combine. Simmer gently for 2–3 minutes.
06 - Stir in Parmesan cheese, red pepper flakes, and season with salt and pepper to taste. Allow sauce to thicken slightly.
07 - Add drained penne and broccoli to the skillet, tossing to coat with sauce. Return steak to the pan, including any juices, and mix until everything is well combined and heated through. Remove from heat and garnish with chopped parsley. Serve immediately.
