These Cheesy Meatball Subs are so easy to make and delicious. I baked the meatballs in the oven and tossed them in the slow cooker with homemade Spaghetti Sauce.

Hello, My name is Diane Roark. I blog at Recipes For Our Daily Bread and Our American Travels. Each month I look forward to sharing one of my family’s favorite recipes here at Princess Pinky Girl. With my busy family, I am always making family friendly easy recipes. I am thankful to have a chance to share one of my recipes with you today. I hope you enjoy these Cheesy Meatball Subs.
I make these Cheesy Meatball Subs especially for my youngest daughter, Diana, who will be 13 this summer. She loves everything made with red sauce including marinara pasta, pizza, spaghetti, and more. She is only weighs seventy-five pounds, but can eat two of these subs and claims they are the best sandwich ever. No! We are not Italian, and neither is Diana. She was adopted from Eastern Europe. She simply loves her Italian food including these Cheesy Meatball Subs.
I enjoy making these Cheesy Meatball Subs because they are pretty easy to make. I use an ice cream scoop to place the meatballs on a baking sheet. When the meatballs are done, I place them in my homemade Spaghetti sauce in my slow cooker. They stay warm for when you are ready to make your Cheesy Meatball Subs. I let everyone build their own meatball sub on a soft hoagie roll or even a hot dog bun. My kids have always enjoyed preparing their plate even when they were younger. Diana especially enjoys building a Cheesy Meatball sub. She simply adds some Mozzarella cheese on the bottom of the sub. Next, she adds the meatballs with the spaghetti sauce. She then tops it off with more Mozzarella cheese.
These meatballs and spaghetti sauce are perfect over pasta too, or I have even mixed the pasta in with the sauce. I have never tried adding my uncooked pasta to the slow cooker, but I plan on trying it soon. I will let you know if it works.

Do you have any easy recipes you can share with me that include red sauce? My daughter Diana would love a new recipe. Do you have a favorite Sub sandwich?
Cooking Tip:
- Use an ice cream scoop to make perfect meatballs every time.
- Remove bay leaf from your spaghetti sauce before adding the meatballs.
- You can brown the meatballs in a skillet on top of the stove using a couple tablespoons of vegetable oil instead of browning the meatballs in the oven. After browning the meatballs on all sides, add them to the slow cooker filled with spaghetti sauce.
