01 - Bring a large pot of salted water to a boil. Cook penne according to package directions until al dente. Add broccoli florets during the last 2 minutes of cooking. Drain thoroughly and set aside.
02 - Season steak strips with 1/2 teaspoon salt and 1/2 teaspoon black pepper. Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Sear steak for 2-3 minutes per side until just cooked through. Transfer to a plate and cover loosely to keep warm.
03 - Add remaining olive oil to the same skillet. Sauté minced garlic until fragrant, approximately 1 minute.
04 - Add halved cherry tomatoes to the skillet and cook for 2-3 minutes until just softened.
05 - Reduce heat to medium. Pour in heavy cream, stirring constantly to incorporate. Simmer gently for 2-3 minutes until slightly thickened.
06 - Stir in Parmesan cheese and crushed red pepper flakes. Season with salt and pepper to taste. Allow sauce to thicken slightly, about 1 minute.
07 - Add drained penne and broccoli to the skillet, tossing to coat evenly with sauce. Return steak and any accumulated juices to the pan. Mix until all components are well combined and heated through.
08 - Remove from heat immediately. Garnish with chopped fresh parsley. Serve while hot.
