Preheat the oven to 350 degrees and prepare a casserole dish with nonstick cooking spray.
Cook pasta according to package directions. Then drain and set aside.
In a large pot cook sautéed onion and garlic and allow to cook for 1-2 minutes on a lower heat to make sure your garlic does not burn then add in ground beef and cook and crumble.
Add in diced tomatoes and tomato paste then season with chili powder, salt, cumin, and pepper.
Add cook and drained elbow macaroni to your beef and tomatoes and mix well. Mix in 1 cup of shredded cheese and mix until melted.
Add your ingredients to your prepared casserole dish and top with remaining cheese. Bake for 30 minutes until cheese is melted.
