It takes a tender hand to make a light meatball. The key is in the rolling; you want to leave air pockets in the meatballs, so shape the balls gently in your hand, making sure not to squash them.
1 tablespoon olive oil
2 cups minced onion
1/4 cup water
4 cups lower-sodium marinara sauce
1/2 cup chopped fresh basil
1/4 cup (1 ounce) grated fresh Parmesan cheese
1 teaspoon dried oregano
1/4 teaspoon salt
1/4 teaspoon crushed red pepper
1 garlic clove, minced
1 large egg, lightly beaten
3/4 pound ground sirloin
3/4 pound ground pork
1 (1.5-ounce) slice firm white bread, crumbled
8 ounces uncooked spaghetti
Grated fresh Parmesan cheese (optional)
How to Make It
Heat a large skillet over medium heat. Add oil to pan; swirl to coat. Stir in onion; cover and cook 10 minutes. Uncover; stir, and reduce heat to medium. Cook 15 minutes or until onion is tender, stirring frequently. Add 1/4 cup water, stirring to loosen browned bits; cook 10 minutes, stirring frequently. Remove from heat; cool 10 minutes.
Place marinara sauce in a Dutch oven. Bring to a simmer over low heat.
Combine onion mixture, basil, and next 6 ingredients (through egg) in a large bowl. Add ground sirloin, ground pork, and crumbled bread; stir gently to combine. Shape meat mixture into 18 (2-inch) balls. Place meatballs in sauce. Bring to a boil; cover, reduce heat, and simmer 30 minutes or until meatballs are done.
While meatballs simmer, cook pasta according to package directions, omitting salt and fat; drain.
Serve meatballs and sauce over pasta. Sprinkle with Parmesan cheese, if desired.
