Frequently Asked Questions
Can I use different pasta shapes?
Absolutely. Elbow macaroni is traditional, but any small to medium pasta shape works: penne, rotini, ziti, small shells, or even egg noodles. Avoid long noodles like spaghetti, as they don’t hold the sauce and cheese as well in a casserole. Cook the pasta just until al dente so it doesn’t overcook in the oven.
Is this recipe gluten-free?
It can be! Use a gluten-free elbow macaroni (there are many good rice- or corn-based options). All other ingredients—canned tomatoes, tomato sauce, cheese, butter, and seasonings—are naturally gluten-free. Always check labels on processed items like tomato sauce and pre-shredded cheese if you have a severe sensitivity.
What if I don’t have tomato sauce?
You can make a quick substitute by mixing a small can of tomato paste with about ¾ cup of water, plus a pinch of sugar, salt, and Italian seasoning. Or use a can of condensed tomato soup, undiluted. Even a cup of your favorite pasta sauce or pizza sauce works wonderfully.
Why did my casserole turn out dry?
This can happen if the pasta wasn’t quite moist enough before baking, if it was baked uncovered the entire time, or if it was left in the oven too long. Make sure the mixture is saucy when it goes into the dish, cover it for the first 20 minutes, and check it at the shorter end of the bake time. Stirring in an extra splash of tomato sauce or a bit of milk before baking can also help.
Can I make this in a slow cooker?
Yes. Combine the cooked macaroni, tomatoes, sauce, butter, and seasonings in a greased slow cooker, then top with cheese. Cook on LOW for 2–3 hours or HIGH for 1–2 hours, until heated through and the cheese is melted. The pasta will absorb more liquid, so you may want to add an extra splash of sauce or water. The top won’t get as golden as in the oven, but it’s a convenient hands-off method.

Ingredients
- 3 cups cooked elbow macaroni (from about 1½ cups dry)
- 1 can (14.5 oz) diced tomatoes, undrained
- 1 cup tomato sauce or marinara sauce
- 1 cup shredded sharp cheddar cheese
- ½ cup shredded mozzarella cheese
- 2 tablespoons butter, cut into small pieces
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ½ teaspoon black pepper
- ½ teaspoon salt
- ½ teaspoon Italian seasoning
- Optional: 1 lb cooked ground beef or Italian sausage
Instructions
- Preheat oven to 375°F (190°C). Cook the macaroni in salted boiling water until just tender (al dente). Drain well and transfer to a baking dish (8×8 or 9×9-inch).
- Add the diced tomatoes (with their juice), tomato sauce, butter, garlic powder, onion powder, salt, pepper, and Italian seasoning. Stir well to coat the pasta.
- If using cooked ground beef or sausage, stir it in now until evenly distributed.
- Top with cheese. Sprinkle the shredded cheddar and mozzarella evenly over the surface.
- Cover with foil and bake for 20 minutes.
- Remove foil and bake for another 10–15 minutes, until the cheese is melted, bubbly, and golden. Optionally broil for 1–2 minutes for a crispier top.
- Let rest for 5 minutes before serving. Scoop onto plates or into bowls and enjoy warm.
Notes
- For a creamier version, stir in ½ cup sour cream or softened cream cheese before topping with cheese.
- Add cooked onions, bell peppers, garlic, or bacon for extra flavor and texture.
- Serve with garlic bread, a simple salad, roasted vegetables, or fried chicken for a complete meal.
- Store leftovers covered in the refrigerator up to 4 days. Reheat in the oven or microwave with a splash of sauce or water to keep moist.
