Ragu Pasta Bake from Leftover Beef Roast

Meryl Downing
My Simple Beef Roast feeds a crowd or gives lots of great leftovers! Use those leftovers the next night to make a hearty tomato ragu sauce, baked with ziti pasta and melty cheese!

Servings 6


  • 1 T olive oil
  • ½ onion chopped
  • 3 cloves garlic minced
  • 1-2 c leftover beef roast (whatever amount you have is fine, discard white fat)
  • ½ c red wine (optional)
  • 1 28oz can tomatoes whole peeled and pulsed in a food processor, or diced or crushed
  • 1 5oz can tomato paste
  • ½ t kosher salt
  • 6 grinds fresh black pepper
  • c fresh Italian herbs like basil, oregano, thyme or parsley (or 2t dried Italian seasoning)
  • 1 lb Ziti pasta or any short pasta (rigatoni, penne, etc)
  • 2 c Provolone cheese shredded
  • ½ c Parmesan cheese shredded


  • In a large sauce pot over medium heat, heat oil and saute onion until soft and starting to lightly brown, then add garlic.
  • Add leftover beef roast and stir and break it up to warm through. (Note - This recipe could be made with 1lb ground beef or Italian Sausage in place of the leftover beef roast, just brown it first and then add the onions and go from step 1)
  • Deglaze with wine, letting it cook and sizzle a minute, then add tomato products, break up whole tomatoes in a food processor or by squeezing them into the sauce or chopping them before adding. Rinse out your cans and food processor with ½ cup of water and add to the sauce.
  • Season with salt and pepper, stir well to combine, lower heat and simmer for 30 minutes or longer. It can sit on low heat for a few hours if needed.
  • Set oven to high broil.
  • Cook pasta according to package instructions. When sauce has simmered, add the cooked pasta to the sauce and stir to combine. Transfer to a casserole dish (or you can bake it in the pan it's in if it is oven safe) and top with shredded cheese.
  • Broil 3 minutes or until the cheese is bubbly. Serve with a side salad and crusty bread!
