Recipe Ingredients
- Frozen meatballs: grab your preferred meat version, whether it’s beef, pork, turkey, or chicken, from the freezer section of your local grocery store. We love the Italian frozen meatballs for this recipe. If you have a homemade meatball recipe you like, you can use that instead.
- Marinara sauce: Like spaghetti sauce, marinara creates the pizza-like sauce base for the subs and can be used as an extra topping.
- Seasonings: Italian seasonings and garlic powder give the overall dish a kick of flavor.
- Olive oil spray: used to create a nonstick barrier in the crockpot.
Step-by-Step Instructions
Step One – Add the marinara pasta sauce and seasonings into an olive oil-sprayed crockpot and stir.
Step Two – Add the meatballs to the sauce mixture. Cook on HIGH for 3 hours or LOW for 5 hours. Stir occasionally to avoid burning around the edges. Serve the hot meatballs on sub rolls, hot dog buns or hoagie buns.
Variations
- Sliders: In this crock pot meatball subs recipe, we suggest putting the meatballs on hoagie buns or hoagie rolls, instead, use small slider buns and use only one meatball per bun. Top it with additional sauce and sliced provolone cheese or shredded mozzarella cheese.
- Pizza Subs: Add a pepperoni on top of each meatball for a pizza-flavored sub. Also, top with chopped onions, mozzarella cheese, and olives. (Grated Parmesan cheese and red pepper flakes are great, too!)
- Appetizer: Leaving the meatballs as-is will give you a good appetizer choice. Consider serving with a side of toothpicks and small squares of cheese.
- Casserole: With the meatballs already made, you could easily use them for a cheesy casserole. Cook them in the crockpot according to the directions below and top them with cheese. Serve the meatball sandwiches with pasta and a side of garlic bread or garlic sticks.
Recipe FAQs

Toast your rolls and place the cheese down first on your buns and that adds a layer of protection so the buns don’t fall apart.

I was thinking; since they’re precooked can’t I just make them on the stove? Won’t they overcook in a slow cooker?I will be trying it tonight! Either way it’s a great recipe!
No, they soak up the sauce in the slow cooker.
Will this recipe work for frozen VEGAN meatballs too? Thanks!
Yes, if you like the flavor of them.
Can i use homemade meatballs for this
Yes! I usually do 4-5 hours on low for homemade meatballs.
Look great.will be trying these thank you.
If I’m only making this for 2 people, can I half the recipe and use just one jar of sauce?
Yes! You can’t ruin this recipe. That will work great.
This is truly a great way to utilize the slow cooker! Simple ingredients and minimal prep time make these meatballs a go to for me. Just a cautionary note in terms of the all around flavor. Be sure to use quality Frozen Italian meatballs. Turkey meatballs work fine also, and are obviously a more healthier choice. I was going to refrain from posting name brands here…but I’m going to recommend 2 of them. “Boves” has a version of both turkey or Italian beef. And my personal favorite….Shady Brook Farms Turkey meatballs. They sell them fresh at the supermarkets in quantities of 16 per package. What I do is freeze them first then use them in this recipe. Absolutely delicious! Thanks for posting a very good one here!
