Prepare the Ingredients: Gather all ingredients. Dice the onion and mince the garlic. Preheat your oven to 350°F (175°C).
Sauté the Onions and Garlic: In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the chopped onion and minced garlic, and sauté until the onion becomes translucent, about 3-4 minutes.
Cook the Ground Beef: Add 1 pound of ground beef to the skillet. Cook until browned and cooked through, breaking it apart with a spoon, around 8-10 minutes. Drain excess fat if necessary.
Season the Beef: Season the cooked beef mixture with salt and pepper to taste. Mix well and set aside.
Make the Creamy Sauce: In a bowl, combine 1/2 cup sour cream and 1 can of cream of mushroom soup. Mix until smooth and well combined, then stir it into the beef mixture.
Assemble the Wraps: Lay out each of the 4 large tortillas. Spoon a generous amount of the beef and cream mixture onto each tortilla, top with 1 cup of shredded cheddar cheese. Roll tightly to form a wrap.
Bake the Wraps: Place the wraps seam side down in a greased baking dish. Bake in the preheated oven for about 15-20 minutes, or until the cheese is melted and bubbly.
Serve: Remove from the oven and let cool for a few minutes before slicing in half. Serve warm with your favorite garnishes or sauces.
