Step‑by‑Step Instructions for Crockpot Meatball Subs
Step 1: Prep Meatballs
In a large mixing bowl, gently combine lean ground beef, plain dry breadcrumbs, minced onion, salt, Worcestershire sauce, egg, and grated Parmesan cheese. Use your hands or a spatula to mix until just combined, avoiding overmixing to keep meatballs tender. Once mixed, shape the mixture into 30 golf ball-sized meatballs, arranging them on a baking sheet for easy transfer.
Step 2: Cook Meatballs
Choose your preferred cooking method to enhance flavor for these hearty crockpot meatball subs. For baking, preheat your oven to 400°F and bake the meatballs on the sheet for 20–25 minutes until browned. Alternatively, you can microwave them on high for about 6 minutes or pan-fry in a skillet over medium heat until they develop a golden-brown crust.
Step 3: Combine in Crockpot
Once the meatballs are cooked, transfer them to a crockpot and pour your favorite spaghetti sauce over them, ensuring they’re fully submerged. Cover the crockpot with its lid and set it to low heat, cooking for 4–6 hours. Stir occasionally to help the flavors meld and prevent sticking.
Step 4: Assemble Subs
As the meatballs simmer, prepare your sub rolls by slicing them open. When ready to serve, spoon 2-3 meatballs along with sauce into each roll and top generously with shredded mozzarella cheese. If desired, place the assembled subs under the broiler for 2-3 minutes to achieve a bubbly, melted cheese finish.
Step 5: Serve and Enjoy
Finally, carefully remove the melted subs from the oven and serve them warm. These succulent crockpot meatball subs make a delightful meal perfect for families, paired easily with crispy potato chips or a fresh green salad for a balanced dinner.

Crockpot Meatball Subs Recipe FAQs
What type of ground beef should I use for meatballs?
I recommend using lean ground beef, ideally 90/10 or 85/15, to keep your meatballs deliciously moist without being greasy. If you’re looking for a leaner option, ground turkey works wonderfully without sacrificing flavor.
How should I store the meatballs and sauce after cooking?
Absolutely! Store cooked meatballs and sauce in an airtight container for up to 4 days in the fridge. Be sure to let them cool completely before covering, as this helps maintain their freshness and prevents excess moisture.
Can I freeze leftover meatballs and sauce?
Very much! You can freeze the meatballs and sauce together for up to 3 months. Make sure they’re cooled entirely before placing them in a freezer-safe container. When you’re ready to enjoy them again, just thaw overnight in the fridge and reheat on the stovetop or microwave.
What if my meatballs fall apart during cooking?
If your meatballs tend to fall apart, it’s likely due to not having enough binder. Increasing your breadcrumb amount or using an extra egg can help hold them together better. Remember to mix gently and shape them evenly to ensure they cook properly.
Are there any dietary considerations for this recipe?
Yes! If you have allergies, ensure everyone enjoys it! For gluten-free diets, use gluten-free breadcrumbs, and choose a gluten-free spaghetti sauce. If you’re watching your dairy, avoid the cheese topping or try a dairy-free alternative for a delicious result.
Can I prepare these meatball subs ahead of time?
Of course! For an even easier meal, you can assemble the subs ahead of time. Just wrap each filled sub tightly in foil and store them in the refrigerator for up to 2 days. When it’s time to heat them, you can bake them in the oven for that classic cheesy finish.
