Cooking Tips

  • Deglaze: After searing your Italian meatballs add a little liquid to the pot and deglaze the bottom of the pot. Use a wooden spoon and scrape away and food particles stuck to the pot. This will prevent a burn notice when cooking your meatball and pepper mixture.


  • Additions: I like to add fresh basil, kosher salt and freshly ground black pepper to my Instant pot meatballs and peppers.
  • Cheese: To make this into a cheesy meatball sub add some grated parmesan cheese to the dish.
  • Homemade Meatballs: If making homemade meatballs with peppers, be sure to add minced garlic and plenty of herbs to your ground beef mixture. If making homemade feel free to use ground turkey if preferred.
  • Frozen Peppers: You can use fresh bell peppers or frozen peppers for this recipe. We use red bell pepper but you can opt for yellow bell pepper or green peppers for a change of color.

Storage & Reheating Instructions

  • Refrigeration: Allow your meatball subs to cool to room temperature before storing. Place them in an airtight container and refrigerate within 2 hours of assembly. Consume within 2-3 days for optimal freshness.
  • Freezing: For longer storage, freeze meatball subs individually. Wrap them tightly in plastic wrap or aluminum foil, place in a freezer bag, and store for up to 2-3 months.
  • Reheating: When ready to enjoy, reheat refrigerated or thawed meatball subs in the oven or microwave until warmed through. For frozen subs, thaw in the refrigerator before reheating. Toasting in the oven enhances the crispy texture of the bread.

Ensure the delightful taste of your meatball subs stays intact with these convenient storage and reheating instructions!

What to Serve With This Recipe?

  • French Fries: Crispy fries tossed with garlic, Parmesan cheese, and parsley make a delicious and indulgent side dish that pairs perfectly with meatball subs. If having meatballs without bread, you could also try mashed potatoes.
  • Italian Chopped Salad: A fresh and flavorful Italian chopped salad with crisp lettuce, tomatoes, cucumbers, olives, and Italian dressing provides a light and refreshing contrast to the hearty meatball subs.
  • Roasted Vegetables: Roasted vegetables such as zucchini, bell peppers, and onions seasoned with Italian herbs make a nutritious and flavorful side dish that complements the flavors of the meatball subs.
  • Creamy Coleslaw: Creamy coleslaw with cabbage, carrots, and a tangy dressing offers a cool and refreshing accompaniment to the warm and savory meatball subs.


Can You Cook Frozen Meatballs in the Instant Pot?

You can cook meatballs in the Instant pot fresh or frozen. Frozen meatballs in the Instant Pot will need an extra 3 minutes cooking time.

We love to cook Instant pot frozen meatballs as I can just grab them from the freezer and we don’t have to wait fro defrosting. Our meatballs always taste just as cook when pressure cooked from frozen.

I’d recommend cooking your meatballs from frozen rather than defrosting meatballs in a microwave before cooking.
