Bubble Up Meatball Sub Casserole Homemade Meatballs - Recipe Diaries (2024)

I shared this recipe for Meatball Sub Casserole before having my own meatball recipe on this site and that is why I decided to update it. I remade it with that same meatball recipe and it was so much better than using meatballs frozen from a bag. And guess what?! The points are even lower than what they previously were. Yay! There will be meatballs leftover depending on how much you think will be enough. Just save them for later use or freeze the meatballs.

This recipe was a twist on the Bubble Up Enchilada recipes that were popular back in the days. I love them because they are easy to assemble and easy to change the ingredients up if you don’t like the ingredients used.

What Ingredients do I need?

• Ground Beef - I used 96/4 lean ground beef to help keep the points low.
• Egg - 1 large
• Bread Crumbs - I used Panko
• Garlic Cloves - fresh or ground garlic powder
• Onions - can also use chives
• Grated Parmesan Cheese - Do not use the grated parmesan cheese in plastic green bottles. It has a long listed of ingredients on the back. Buy the real stuff and shred it yourself.
• Salt and Pepper - to taste
• Marinara Sauce - Can make your own or use store-bought. I like Rao’s when I don’t feel like making everything homemade. 🙂
• Canned Biscuits - found in the refrigerated section of the grocery store.
• Mozzarella Cheese - part-skim or reduced-fat if following WW, can use full-fat anytime
