Start by gathering your ingredients and tools. This will save you time and ensure a smooth cooking process. You’ll need a large skillet and a saucepan. Wash the veggies and chop the garlic.

Take your steak cubes and pat them dry with paper towels. Season generously with salt and pepper.

Heat the olive oil in a large skillet over medium-high heat. Add the steak cubes in batches, searing each side for about 2-3 minutes until nicely browned. Remove from the skillet and set aside.

In the same skillet, lower the heat to medium and add the butter. Once melted, add the minced garlic and sauté for about 30 seconds until fragrant.

Return the seared steak cubes back to the skillet with the garlic butter. Toss to coat the steak bites.

In a separate saucepan, melt another tablespoon of butter over medium heat. Add freshly minced garlic and sauté for 30 seconds. Pour in the heavy cream and bring to a gentle simmer.

Slowly stir in the Parmesan cheese and keep stirring until it melts completely. Season with salt, black pepper, and optional red pepper flakes.

Pour the creamy Parmesan sauce over the sautéed steak bites in the skillet, stirring well to combine.

Check the consistency of your cream sauce. Add a splash of milk or broth if too thick, or let simmer longer if too thin.

Transfer to a serving platter, garnish with chopped parsley, and serve.
