Why Crockpot Meatball Subs Are a Must-Try

This dish has a long-standing reputation as one of the coziest, most filling sandwiches out there.

This makes the recipe ideal for busy families, working professionals, or anyone looking for a no-fuss dinner solution.

Tips for the Best Crockpot Meatball Subs

Here are a few expert tips to get the absolute best results:

• Don’t Overcook the Meatballs: Even in a crockpot, they can become mushy if left too long on high heat. Stick to the suggested cooking times.

• Toast the Rolls: It helps prevent sogginess and adds a satisfying crunch.

• Layer Cheese Strategically: Cheese beneath and on top of the meatballs makes the sandwich extra gooey.

• Use a Liner in the Crockpot: For easy cleanup, especially if the sauce splatters a bit during slow cooking.

How to Store and Reheat

These subs are ideal for storing and reheating. If you’re making them ahead or have leftovers, here’s how to keep them fresh.

Storage:

• Meatballs & Sauce: Store in an airtight container in the fridge for up to 4 days.

• Freezing: Freeze the meatballs and sauce (separately from the bread) for up to 3 months. Thaw overnight in the fridge before reheating.

• Rolls: Store separately in a bread bag or freeze for longer storage.

Reheating:

• Microwave: Quick but be careful not to overcook.

• Stovetop: Reheat meatballs and sauce on low heat until warmed through.

• Oven: Assemble your sub and bake at 350°F for 10–12 minutes to get that fresh-baked feel again.
