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 and set aside.
02 - Season steak strips with 1/2 teaspoon salt and 1/2 teaspoon pepper. Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Sear steak 2 to 3 minutes per side until just cooked through. Transfer to a plate and cover loosely.
03 - In the same skillet, add remaining olive oil. Sauté minced garlic until fragrant, approximately 1 minute.
04 - Add cherry tomatoes to the skillet and cook 2 to 3 minutes until just softened.
05 - Reduce heat to medium. Pour in heavy cream, stirring constantly. Simmer gently for 2 to 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 to coat evenly. Return steak with accumulated juices to the pan. Mix until everything is well combined and heated through. Remove from heat, garnish with parsley, and serve immediately.
