Crockpot Dump and Go Meatball Subs Ingredients
For the Meatballs
- Frozen Meatballs – The main protein source; feel free to swap in homemade meatballs if you have them on hand.
For the Sauce
- Marinara Sauce – Adds a rich tomato flavor that’s essential for a comforting sub; avoid plain sauces for a more flavorful experience.
- Garlic Powder – Enhances the flavor profile; using fresh garlic will add a delightful aroma to your dish.
- Italian Seasoning – Provides a blend of herbs for depth; feel free to replace with individual herbs like oregano or basil for a tailored taste.
For Assembling
- Hoagie Rolls – Hold up beautifully to the sauce and meatballs; firm bread works as a great substitute if hoagies aren’t available.

Step‑by‑Step Instructions for Crockpot Dump and Go Meatball Subs with Marinara
Step 1: Prepare the Ingredients
Start by placing your frozen meatballs straight into the crockpot, ensuring they’re evenly spaced for even cooking. Pour in a generous amount of marinara sauce over the meatballs, followed by a sprinkle of garlic powder and Italian seasoning. This combination creates a luscious flavor foundation that will envelop the meatballs, making your Crockpot Dump and Go Meatball Subs deliciously aromatic.
Step 2: Slow Cook the Meatballs
Cover the crockpot with its lid and set it to cook on LOW for 6–7 hours or on HIGH for 3–4 hours. As the meatballs simmer in the sauce, they will slowly heat through and absorb the savory flavors. You’ll know they’re done when the meatballs are tender and the sauce is bubbling, filling your kitchen with mouthwatering scents.
Step 3: Toast the Hoagie Rolls
About 10-15 minutes before you’re ready to serve, preheat your oven to 375°F (190°C). Slice the hoagie rolls open and spread a little butter on the insides if you’d like. Place the rolls on a baking sheet and toast them in the oven for approximately 5–7 minutes, or until they are golden and crisp—this step adds a wonderful texture to your Crockpot Dump and Go Meatball Subs.
Step 4: Assemble the Subs
Once your meatballs are cooked and the rolls are toasty, it’s time to create your subs! Using tongs, place 4-5 meatballs into each toasted hoagie roll, allowing the savory marinara sauce to drip down. For a gooey finish, generously top the meatballs with shredded mozzarella and a sprinkle of grated Parmesan cheese to enhance the flavor.
Step 5: Broil for Perfection
Set your oven to broil, and carefully transfer the assembled meatball subs to the oven for 2–3 minutes. Watch closely as the cheese melts and begins to bubble, creating that inviting, golden crust. This finishing touch makes your Crockpot Dump and Go Meatball Subs irresistibly cheesy and satisfying.
Step 6: Garnish and Serve
Once the cheese is wonderfully melted, remove the subs from the oven and let them cool for a moment. For a burst of freshness, sprinkle some chopped parsley over the top of each sub before serving. Enjoy these warm, cheesy, and deliciously messy meatball subs with family and friends for a delightful meal!

Crockpot Dump and Go Meatball Subs with Marinara Recipe FAQs
How do I choose the best frozen meatballs?
Absolutely! When selecting frozen meatballs, look for those with minimal preservatives and a good balance of meat and filler. Check the ingredient list for items like bread crumbs and spices. Homemade meatballs can provide a fresher flavor if you have the time to prepare them!
What’s the best way to store leftover meatball subs?
For the freshest leftovers, store the meatballs and marinara sauce separately from the hoagie rolls in airtight containers. They can keep for about 3 days in the fridge. This way, the bread won’t get soggy and each component will retain its flavor and texture.
Can I freeze the meatball subs?
Yes, you can freeze the meatballs and marinara sauce together! Simply pack them in an airtight container or freezer bag for up to 2 months. When you’re ready to enjoy them, thaw in the fridge overnight and reheat in a saucepan. Toast fresh rolls right before serving for that delightful crispiness!
What if my meatballs are still frozen when I start cooking?
No worries at all! If you start cooking with frozen meatballs, just set your crockpot on HIGH for about 4 hours. This will ensure they are fully heated and cooked through. The key is to make sure they reach an internal temperature of 165°F to guarantee they’re safe to eat.
Are there any dietary considerations I should keep in mind?
Very good question! If you’re hosting guests with dietary restrictions, consider using gluten-free rolls or turkey meatballs for a lighter option. Additionally, you can omit the cheese or substitute it with vegan cheese for a lactose-free version. I often make these substitutions without losing any of the delicious flavors!
How do I know when the meatballs are fully cooked?
To ensure your meatballs are fully cooked, use a meat thermometer. They should reach an internal temperature of 165°F. You’ll also want to check that they’re heated through and the sauce is bubbling. If you’re unsure, simply cut one open—the meat should be steaming and no longer pink inside.
