01 - Bring a large pot of salted water to a boil. Cook penne according to package directions until al dente. During the final 2 minutes, add broccoli florets. Drain thoroughly and set aside.
02 - Season steak strips with 1/2 tsp salt and 1/2 tsp black pepper. Heat 1 tbsp 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 1 tbsp 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 combine. Simmer gently for 2-3 minutes until slightly thickened.
06 - Stir in Parmesan cheese and 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 along with any accumulated juices to the pan. Mix until all components are well combined and heated through. Remove from heat, garnish with fresh parsley, and serve immediately.
