Meatball Sub Casserole

It's been a while since we've had a meatball sandwich and boy, have I been craving it! I mean, it's hard not to like cheesy meatballs right? However, I'm not a fan of the mess that I always make with meatball subs as the meatballs try and escape the sandwich bread! So, I decided to make a casserole version instead. So why should you make this tonight?

• it takes less than an hour
• it's deliciously cheesy
• it uses frozen meatballs to save time
• veg snuck in for those picky eaters

What You'll Need to make this meatball casserole

• Pillsbury Country Style Biscuits
• marinara sauce: here's how I make homemade marinara if you've got time
• garlic powder
• onion
• asparagus
• shredded cheese
• frozen meatballs

How To Make This One Pot Meatball Sub Casserole

• Heat oven to 375F.
• Cut up the biscuit dough in half.

• Lightly grease a baking dish and place the biscuits into the it, mixing in the marinara sauce, garlic powder, onion, and asparagus.

• Place ¼ of the cheese on top of the mixture.

• Nestle in the meatballs into the baking dish.

• Add in ¼ of the cheese on top of the meatballs.

• Cover the dish with foil, bake for 30 minutes, uncover the foil, add the rest of the cheese on top, and bake for another 10-15 minutes, until the cheese have melted.
• Serve once done.

Recipes Variations

• Swap the onions and asparagus for different vegetables such as peppers, mushrooms, etc.
• Stir in fresh herbs such as rosemary and basil.
• Swap beef meatballs for chicken meatballs (here's how I make homemade chicken meatballs).

Tips and Notes

• If you like your biscuits a little bit crispier, arrange the biscuit dough so parts of it sticks up between the sauce and meatballs.
• To avoid extra liquid, I thaw my meatballs before baking.
• I only use half an onion since too many onions release too much liquid.
