How to Make Crockpot Meatball Subs Directions
Making these Crockpot Meatball Subs is straightforward and requires just a few simple steps:
- Begin by placing the frozen meatballs into your crockpot. There’s no need to thaw them beforehand; they will cook perfectly from frozen.
- Pour the marinara sauce over the meatballs, ensuring they are all well-coated with the sauce. This mixture will create a flavorful base that infuses the meatballs as they cook.
- Once the meatballs and sauce are in the crockpot, cover it with a lid. Your next step is to set the heating level. You can either cook on low for about 4 to 6 hours or opt for the high setting for 2 to 3 hours. Either method will yield tasty meatballs that are hot and ready.
- While the meatballs are cooking, preheat your oven to 375°F (190°C). This will be essential for toasting your hoagie rolls.
- After cooking time is complete, check the doneness of the meatballs. They should be hot throughout. If they need a little more time, let them cook for an additional 30 minutes on low.
- When your meatballs are ready, take the hoagie rolls and place them on a baking sheet. Pop them in the oven for about 5 minutes to lightly toast them. This step adds a nice crunch to the outside, making them even more enjoyable when filled.
- Once the rolls are toasted, remove them from the oven and pile the meatballs into each roll generously. This is the fun part! Be sure to load them up with lots of saucy meatballs.
- Finally, sprinkle shredded mozzarella cheese on top of each meatball-filled roll. For that gooey, melty effect, place the loaded rolls under the broiler for 1 to 2 minutes or until the cheese is melted and bubbly. Keep a close eye on them to prevent burning.
- Serve these tasty meatball subs immediately. Optionally, you can garnish with fresh basil or parsley for a delightful touch. Just like that, you’ve created an irresistible dish perfect for any occasion!
How to Serve Crockpot Meatball Subs
Serving your Crockpot Meatball Subs can elevate your dining experience from ordinary to extraordinary. You can serve them as a hearty dinner option accompanied by sides like chips, a simple salad, or garlic bread for that classic Italian pasta night feel. If you want a casual vibe, set up a self-serve station where everyone can help themselves to the meatball subs. This approach allows guests to customize their sandwiches with additional toppings, such as sliced jalapeños, extra cheese, or even a drizzle of hot sauce for those who enjoy a kick.
For a festive touch, you could also position your garnishes, like fresh basil or parsley, in small bowls nearby to encourage people to create their ideal combination.

Expert Tips: Crockpot Meatball Subs
To make the most of your Crockpot Meatball Subs, consider the following expert tips:
- Quality Marinara Sauce: The sauce is crucial. Opt for high-quality marinara, as it will significantly impact the taste of your meatballs. If you’re feeling adventurous, try making your own marinara for a fresh twist.
- Meatball Variety: While frozen meatballs are incredibly convenient, don’t hesitate to explore different types. Beef, turkey, chicken, or even plant-based meatballs can cater to various dietary preferences.
- Broiling Time: Be cautious while broiling the rolls to melt the cheese. A minute or two can make a huge difference, so keep an eye on the oven to achieve that perfect golden-brown texture without overcooking.
- Add Veggies: For a healthier version, add some sautéed bell peppers, onions, or mushrooms into the mix. This not only adds a nutrient boost but also enhances the flavor and texture of your meatball subs.
- Slow Cooker Size: Ensure your slow cooker is large enough to accommodate the pound of meatballs and sauce. A 4-quart slow cooker is typically ideal for this recipe.
By adhering to these tips, you’ll create a mouthwatering meal that impresses every time!
How to Store Crockpot Meatball Subs
Storing leftovers from your Crockpot Meatball Subs is easy and convenient. Allow the meatballs and sauce to cool to room temperature. Then, you can store them in an airtight container in the refrigerator for up to 3 days. If you have extra hoagie rolls, it’s best to keep the meatballs separate to prevent sogginess.
For longer storage, consider freezing the meatball mixture. Place it in a freezer-safe container, and it can stay fresh for up to three months. When you’re ready to enjoy them again, simply thaw overnight in the refrigerator and reheat on the stovetop or in the microwave until warmed through.
Variation of Crockpot Meatball Subs
While the classic meatball sub is a beloved choice, there are plenty of variations to keep your meals exciting and new. Here are some ideas to inspire your next cooking adventure:
- Italian Meatball Subs: Add Italian seasonings like oregano, garlic powder, or crushed red pepper flakes to the meatball mixture for an extra kick.
- BBQ Meatball Subs: Swap out marinara for barbecue sauce for a smoky flavor. Top your subs with coleslaw for a fantastic contrast in taste and texture.
- Spicy Meatball Subs: Use spicy Italian sausage meatballs for a hotter version of this dish. Serve with pepper jack cheese for an extra heat boost.
- Veggie Meatball Subs: For a vegetarian option, make or buy plant-based meatballs and use a robust marinara sauce. You can also add toppings like spinach, zucchini, or roasted peppers.
- Cheesy Meatball Subs: For cheese lovers, mix in different cheese varieties to the sauce or sprinkle additional cheese on top before broiling. Try provolone or even cheddar for a twist.
These variations can keep things exciting and allow you to cater to everyone’s taste in your household or gatherings.
