Every time that I make this cheesy baked spaghetti, I get requests for the recipe. It puts a different spin on pasta and is great for any meal. The leftovers, if there are any, also freeze well for a quick dinner later in the week. —Ruth Koberna, Brecksville, Ohio

Ingredients

1 cup chopped onion
1 cup chopped green pepper
1 tablespoon butter
1 can (28 ounces) diced tomatoes, undrained
1 can (4 ounces) mushroom stems and pieces, drained
1 can (2-1/4 ounces) sliced ripe olives, drained
2 teaspoons dried oregano
1 pound ground beef, browned and drained, optional
12 ounces spaghetti, cooked and drained
2 cups shredded cheddar cheese
1 can (10-3/4 ounces) condensed cream of mushroom soup, undiluted
1/4 cup water
1/4 cup grated Parmesan cheese

Directions

In a large skillet, saute onion and green pepper in butter until tender. Add the tomatoes, mushrooms, olives, oregano and, if desired, ground beef. Simmer, uncovered, for 10 minutes.

Place half of the spaghetti in a greased 13x9-in. baking dish. Layer with half of the vegetable mixture and 1 cup cheddar cheese. Repeat layers.
In a small bowl, combine soup and water until smooth; pour over casserole. Sprinkle with Parmesan cheese. Bake, uncovered, at 350° until heated through, 30-35 minutes.

Test Kitchen Tips

To prevent pasta from sticking together when cooking, use a large pot and 3 quarts of water for each 8 ounces of pasta you plan to cook. Add 1 tablespoon cooking oil to the water. (This also prevents boiling over.) Bring the water to a full rolling boil before stirring in the pasta. Stir several times to separate the pasta until the water returns to a boil.

You can convert any recipe from 13x9 to 8x8—here's how.
