When you think of spaghetti and meatballs, the ultimate childhood comfort food comes to mind. It was one of my all-time favorite meals, right behind my mom’s barbecue ribs with her homemade Zippy barbecue sauce.
You Can Have A Healthy Diet and Pasta Dishes, Too!
That magical combination of flavor and texture that can usually win over even the pickiest kids. I don’t eat much pasta anymore, but when I do eat noodles, I try and opt for a higher protein version like lentil, quinoa, edamame or black bean pasta.
Another healthy carb alternative that I love to replace for pasta is spaghetti squash and zucchini. This Zucchini Spaghetti has been a favorite in our family for years and when cooked properly, you can still achieve that al-dente texture. Have you tried veggie noodles yet??!
If not, you definitely need to give them a try! This Spaghetti Squash Meatball Casserole is a wonderful smart carb alternative to heavy, calorie-laden, pasta dishes and a great source of muscle-building lean protein. It’s full of incredible flavor and loaded with good nutrients to keep your body properly fueled.

The first step in preparing this dish is to bake the squash. Cut squash in half lengthwise and brush a little olive oil or olive oil spray on the inside. Place squash inside portion down and bake at 350 degrees for 35-45 minutes. While squash is baking, make the meatballs and refrigerate until the squash is done. When squash comes out of the oven, raise heat to 375 degrees F.
Scoop out and discard the seeds after baking, then shred the squash with a fork.
Next, brown the meatballs in a little olive oil in a skillet and transfer them to a baking sheet to cook for 20 minutes. While meatballs are cooking, add a little more olive oil to the pan and cook the onion and garlic until onion is soft. Add in shredded squash, cheese and seasonings.
Spread a thin layer of sauce on the bottom of a 9X13 baking dish.
Top with squash.
Arrange meatballs on top of the shredded squash mixture.
Pour sauce over the dish, making sure to coat all of the meatballs. Next, add the sliced mozzarella.
Bake casserole at 350 degrees F for 30 minutes.
Serve and enjoy.
