Ingredients

Scale
  • 1 pound ground beef
  • 1 tablespoon olive oil
  • 1 small onion, diced
  • 2 cloves garlic, minced
  • 1 can (15 oz) tomato sauce
  • 1 tablespoon tomato paste (optional)
  • 1 teaspoon Italian seasoning
  • Salt and black pepper, to taste
  • 8 ounces wide egg noodles
  • 1 cup sour cream
  • 1 cup small curd cottage cheese
  • 1 1/2 cups shredded cheddar cheese, divided
  • 2 tablespoons chopped parsley or green onion (optional, for garnish)

Instructions

  1. Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish.
  2. Bring a large pot of salted water to a boil. Cook the egg noodles until just al dente, about 7 minutes. Drain the noodles and set them aside.
  3. In a large skillet, cook the ground beef over medium heat until it is browned. Drain any excess fat.
  4. Add the diced onion and minced garlic to the skillet with the beef. Sauté for 2–3 minutes until the onion is soft.
  5. Stir in the tomato sauce, tomato paste (if using), Italian seasoning, salt, and pepper. Let this mixture simmer for 5 minutes.
  6. In a large bowl, combine the cooked egg noodles, sour cream, cottage cheese, and 1 cup of the shredded cheddar cheese. Mix gently.
  7. Spread half of the noodle mixture evenly into the prepared baking dish. Top this layer with half of the beef sauce.
  8. Repeat the layers with the remaining noodle mixture and the remaining beef sauce.
  9. Sprinkle the remaining 1/2 cup of cheddar cheese over the top layer.
  10. Bake uncovered for 25–30 minutes, or until the casserole is bubbly and the cheese is golden brown on top.
  11. Let the casserole rest for 5–10 minutes before you cut and serve it. Garnish with parsley or green onion if you wish.

Notes

  • For an extra rich flavor, use tomato paste in the beef sauce.
  • You can assemble this entire casserole ahead of time and keep it covered in the refrigerator for up to one day before baking. Add about 10 minutes to the bake time if cooking straight from the fridge.
  • This recipe works well with ricotta cheese if you prefer not to use cottage cheese.
