Preheat the oven to precisely 400°F. Ensure that the inside of a 9x13 casserole dish is adequately greased with cooking spray to prevent sticking.
Using a large skillet, place it over medium heat. Cook the bacon until it achieves a crisp texture. Subsequently, extract the bacon with a slotted utensil and allow it to drain, placing it atop absorbent paper towels.
Utilizing the residual fat in the skillet, introduce the ground beef. Cook it until it achieves thorough doneness, which approximately takes 8 minutes. After the ground beef is adequately cooked, remove any excess grease. Integrate the Montreal steak seasoning into the beef, ensuring an even distribution of flavor.
In an adequately sized mixing vessel, amalgamate all the aforementioned ingredients. Once an even consistency and distribution are achieved, transfer the contents to the previously prepared casserole dish.
Insert the dish into the preheated oven. Allow it to bake for a duration of 30 minutes or until it exhibits thorough cooking. Once completed, it is ready for serving.
