These are truly the easiest meatball subs! We took a bunch of shortcuts by making everything store-bought and these are a winner! All you do is let frozen meatballs cook in a crockpot with sauce and then layer up your subs. It’s the perfect dinner for a busy day and you really can’t mess it up. We got mostly everything from Costco to make it a Costco dinner, but you could easily substitute with whatever works for you!
What you need to make the easiest meatball subs + substitutions:
- Baguettes- Any baguette will do! We just bought baguettes from Costco! You could also use any kind of bread you prefer like hoagie rolls or ciabatta.
- Italian meatballs- We got the frozen Italian meatballs from Costco. These are so good and quick for an easy meal! You can use our homemade meatballs or any kind that you’d like!
- Marinara- Our favorite jarred sauce is hands down Rao’s. Nothing compares in my opinion. We usually buy the giant jars from Costco anyway, but of course any marinara you like will work.
- Provolone cheese- You could use provolone or fresh mozzarella here. We used provolone and actually didn’t get this one from Costco, because we didn’t need that much cheese haha. I mean we always need cheese, but you know what I mean!
- Pesto– This is an extra and not required, but totally adds an extra fun flavor to these! The Costco pesto is hands down my favorite when I’m not making my own.
- Basil- For garnish if you’d like! Optional, but highly suggest it.
