Start by making your homemade enchilada sauce. You can find a simple recipe online, or use your favorite version. This sauce is essential for adding depth to your Beef Enchiladas.
In a large skillet, heat the vegetable or canola oil over medium heat. Add the ground beef and cook until browned, breaking it up with a wooden spoon. Season with salt, pepper, and any additional spices to taste.
Preheat your oven to 350°F (175°C). Take one tortilla, add a scoop of the cooked beef mixture, and sprinkle some grated Monterey Jack cheese on top. Roll the tortilla tightly and place it seam-side down in a greased casserole dish. Repeat until all tortillas are filled.
Pour the homemade enchilada sauce generously over the rolled tortillas, ensuring they are well-coated. Sprinkle any remaining Monterey Jack cheese on top.
Cover the casserole dish with aluminum foil and bake in the preheated oven for about 20 minutes. Remove the foil and bake for an additional 10 minutes, or until the cheese is melted and bubbly.
Once out of the oven, let the enchiladas cool for a few minutes. Serve them topped with sour cream and fresh cilantro, if desired. Enjoy your delicious Beef Enchiladas with a side of your favorite toppings!
