How to Make Seashell Casserole

  1. Preheat oven to 350°F (175°C).
  2. Spray a large casserole dish (9x13 inch) with cooking spray.
  3. In a large skillet over medium-high heat, brown 1 lb of ground beef and 1 medium chopped onion until the beef is cooked through and the onion is softened. Drain off any excess grease.
  4. Return the beef and onion mixture to the skillet. Stir in 24 oz of tomato sauce, 10.75 oz can of condensed cream of mushroom soup, 1 cup of shredded cheddar cheese, 1 tsp salt, 1/2 tsp black pepper, and 2 minced cloves of garlic.
  5. Bring to a simmer and cook uncovered for 5-7 minutes, stirring occasionally, to allow the flavors to meld.
  6. While the meat mixture simmers, cook 1 (16 oz) package of small pasta shells according to package directions until al dente. Drain well.
  7. Add the cooked pasta to the meat mixture in the skillet and stir to combine thoroughly.
  8. Pour the pasta and meat mixture into the prepared casserole dish.
  9. Sprinkle the remaining 1 cup of shredded cheddar cheese evenly over the top.
  10. Bake for 20-25 minutes, or until the cheese is melted, bubbly, and lightly golden brown.
