1-Preheat your oven: Preheat your oven to 375°F (190°C) and cook the rice as instructed on the package.

2-Cook the steak: Heat 1 tablespoon of olive oil in a skillet over medium heat and brown the 500 grams of thinly sliced steak for about 5-7 minutes. The total preparation time is around 45-60 minutes, including cooking and baking. Once the steak is ready, remove it from the pan.

3-Sauté the vegetables: In the same skillet, add 2 tablespoons of butter and sauté the 2 sliced bell peppers, 1 sliced onion, and 2 cloves of minced garlic until tender, which takes about 5-7 minutes. Combine this with the steak mixture. For variations, you could cook 300 grams of ground sausage with the vegetables before mixing.

4-Mix and bake: In a large bowl, mix the cooked rice, steak and vegetable mixture, and Alfredo sauce together thoroughly. Transfer this to a greased casserole dish, about 9×13 inches, and spread it evenly. Sprinkle 1 cup of shredded cheese on top for a bubbly finish.

5-Bake the casserole: Bake the casserole for 20-25 minutes until the cheese melts and turns golden. Let it cool slightly before serving to keep the creamy texture intact. This method ensures the dish is packed with flavors from the primary keyword, Philly Cheesesteak Alfredo Rice Casserole.
