Ingredients about Savory Slow Cooker Meatball Subs
To create your own Savory Slow Cooker Meatball Subs, you will need the following ingredients:
- 24 oz Frozen Italian-style meatballs
- 24 oz Marinara sauce (or your favorite spaghetti sauce)
- 6 Hoagie buns (or brat/large hot dog buns)
- 12 oz Mozzarella cheese, cut in half
- 8 oz Shredded mozzarella cheese
- 1/2 cup Grated Parmesan cheese
- 12 slices Pepperoni (optional)
- 1 tsp Italian seasoning
How to Make Savory Slow Cooker Meatball Subs Directions
Getting started on your Savory Slow Cooker Meatball Subs is a straightforward and enjoyable process. Follow these easy steps, and you’ll have a delicious meal ready in no time.
- Begin by spraying the inside of your slow cooker with non-stick cooking spray to prevent the meatballs from sticking.
- Next, take your frozen Italian-style meatballs and place them in the slow cooker. There’s no need to thaw them in advance; they will cook perfectly from frozen.
- Pour the marinara sauce over the meatballs, ensuring that they are well-coated and nestled in the delicious sauce. This will enhance their flavor as they cook.
- Sprinkle the Italian seasoning on top of the sauce. This adds a wonderful herby flavor profile that compliments the meatballs and sauce beautifully.
- Cover the slow cooker with its lid and cook on low for 6 hours or on high for 3 hours. The long, slow cooking time allows the meatballs to absorb all the flavors of the sauce.
- About 30 minutes before you’re ready to serve, take your hoagie buns and slice them in half. This step is crucial for easily stuffing the meatballs and toppings later on.
- When the meatballs are perfectly cooked, use tongs or a slotted spoon to carefully remove them from the slow cooker. Place the meatballs directly inside the sliced hoagie buns.
- For a cheesy delight, top each meatball with half a slice of mozzarella cheese. You want that melty, gooey texture to happen!
- Next, sprinkle shredded mozzarella over the top of the stuffed buns. Don’t skimp on this step; the more cheese, the better!
- If you like an extra kick, add a slice of pepperoni on top of each sub. This step is totally optional but oh-so-tasty!
- Place the filled buns back in the slow cooker and cover for an additional 15-20 minutes. This will allow the cheese to melt and become wonderfully gooey.
- Finally, serve your meatball subs with a generous sprinkle of grated Parmesan cheese on top. It’s the perfect finishing touch!
How to Serve Savory Slow Cooker Meatball Subs
