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 final 2 minutes of cooking. 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. Sear steak for 2-3 minutes per side until just cooked through. Remove to a plate and cover loosely to retain juices.
03 - Add remaining olive oil to the same skillet. Sauté minced garlic until fragrant, approximately 1 minute.
04 - Stir in halved cherry tomatoes 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.
06 - Stir in Parmesan cheese and red pepper flakes. Season with salt and pepper to taste. Allow sauce to thicken slightly.
07 - Add drained penne and broccoli to the skillet, tossing thoroughly to coat with sauce. Return steak along with accumulated juices to the pan. Mix until everything is well combined and heated through. Remove from heat, garnish with chopped parsley, and serve immediately.
