  • For a chunkier sauce, replace half of the crushed tomatoes with a 14.5-ounce can of Italian seasoned diced tomatoes.
  • Or add the diced tomatoes in addition to the 28-ounce can of crushed tomatoes.

Recipe Variations

  • This dish can be a stand-alone meal or serve it along with a salad or a meat entree. Add some grilled or broiled chicken breasts, fish, or steaks.
  • Of course, you can adapt it with the addition of meat. Brown some ground beef or Italian sausage and add it to the sauce if you like, or add some diced cooked chicken to the tomato mixture.
  • Instead of all mozzarella cheese, consider half cheddar or a blend of mozzarella, cheddar, and provolone. You'll have the extra flavor, and it will still melt beautifully.
  • Mushrooms are another excellent option that will add texture and earthy flavor. Sauté a few ounces of fresh sliced mushrooms along with the onions.
  • The pasta is adaptable as well. Feel free to swap out the penne with elbow macaroni, ditalini, rigatoni, or ziti in the dish.
