Cooking Steps

  • Heat olive oil in a large skillet, then add chopped onion and cook until softened. Stir in minced garlic and cook for an additional minute.
  • Add ground beef to the skillet, brown it completely, and drain any excess grease. Season the beef with salt and pepper.
  • Stir in condensed cream of mushroom soup, milk, and undrained diced tomatoes; bring the mixture to a gentle simmer.
  • Remove the skillet from heat, then stir in the frozen mixed vegetables and cooked pasta, ensuring everything is well coated.
  • Transfer half of the beef and pasta mixture to a 9x13 inch baking dish, then sprinkle with 1 cup of cheddar cheese and spread the remaining mixture over it.
  • Evenly sprinkle the remaining 1 cup of shredded cheddar cheese over the top of the casserole.
  • Preheat oven to 375°F (190°C) and bake for 25-30 minutes until bubbling and the cheese is golden.
  • Let the casserole rest for 5-10 minutes before serving to allow the sauce to set.

Notes

For best results, use a pasta shape that holds sauce well, such as elbow macaroni, penne, or egg noodles. You can also customize the vegetables based on your preference.
