Casserole with Mashed Potatoes Meatballs and Marinara (Gluten Free)

This casserole with mashed potatoes, meatballs and marinara is excellent for a cozy family dinner. Even the pickiest eaters are going to enjoy this meal. I used family favorite ingredients to create the recipe. I haven’t met a person who doesn’t love mashed potatoes, meat, marinara sauce and smoky cheese.

When I thought about this recipe it was cold outside and I was craving a hot and cheesy casserole with some delicious layers. So, I prepared homemade mashed potatoes and I spread them on the bottom of a casserole dish. Then I nested tiny meatballs in the mash and topped them with marinara sauce. The final touch was to cover everything with shredded, smoked Mozzarella and bake. The end result was so good that my whole family loved it. Since I consider you a part of my family, I had to share it with you.

Why should you make this recipe?

This recipe was inspired by a popular Bulgarian dish that consists of mashed potatoes, fried mini meatballs and homemade tomato sauce. I decided to simplify the recipe for you. Instead of frying the meatballs I bake them, and I cover everything with store-bought marinara and cheese. You can prepare my casserole with mashed potatoes, meatballs and marinara much faster and still enjoy the amazing flavors of the original dish.

This casserole is gluten free. I haven’t used breadcrumbs or flour for the meatballs. If you have a gluten intolerance, make sure you read the ingredients of your marinara sauce. Some brands of store-bought marinara may contain gluten.

Tips for preparing mashed potatoes

In my opinion yellow or russet potatoes are best for mashed potatoes. If your yellow potatoes have thin skins, you can boil them without peeling them. There is a lot of fiber and vitamins in the potato skin. If you are going to make the mashed potatoes with the skins on, make sure that you wash them very well.

When I make mashed potatoes I always cut the potatoes to smaller pieces. That ensures faster cooking time and easier mashing.

Always add the potatoes in a pot of cold water and add a generous amount of salt. Your potatoes will absorb salt while boiling. This will make seasoning of your mash much easier.

Warm up your milk for better texture of the mashed potatoes. I warm up my milk in the microwave before incorporating it in the mash.

Tips for making the meatballs

You can use any ground meat that you like for this recipe. I used a mix between pork and beef.

I used a measuring tablespoon to scoop out the meatball mixture. That ensures equally sized meatballs. I ended up with 20 meatballs.

If you are not sure that your meatballs are cooked use a food thermometer. The internal temperature should read 160F.

If I’m going to use a store-bought sauce I read the ingredients carefully. I trust Rao’s when it comes to marinara. Their sauce tastes amazing and it has the ingredients that any marinara should have.
