How to Make Keto Meatball Sub
I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.
- Preheat your oven to 375°F before starting meal assembly. Next, mix ground beef, garlic powder, salt, and pepper in a large bowl until fully combined.
- Form the meat mixture into twelve equal-sized meatballs using clean hands. Then, heat olive oil in a large skillet over medium-high heat for three minutes.
- Sear the meatballs for five minutes until golden brown on all sides. Afterward, pour sugar-free marinara sauce directly over the seared meatballs in the pan.
- Simmer the mixture on low heat for ten minutes until fully cooked through. Meanwhile, slice your low-carb sub rolls open lengthwise without cutting all the way through.
- Brush the inside of each roll generously with melted garlic butter. Then, bake the empty rolls on a lined baking sheet for five minutes until crisp.
- Spoon the hot cooked meatballs and rich sauce into the toasted rolls. Finally, top each sub with shredded mozzarella and broil for two minutes until bubbling.
- Pro Tip: Broil the cheese-topped subs for precisely ninety seconds while watching closely to prevent burning the edges.
Common Mistakes to Avoid
- Skipping the meatball sear leaves your beef dry and strips away rich caramelized flavor.
- Overfilling the sub rolls causes heavy sauce to spill out and makes the bread soggy.
- Using sugary store-bought marinara ruins the keto profile by introducing hidden carbohydrates.
Required Equipment
- Large skillet — ensures even browning and helps develop deep flavor on the meatballs.
- Baking sheet — holds the sub rolls securely while they toast in the oven.
- Meat thermometer — guarantees internal meat temperature reaches safe levels quickly.
Caleb's Recipe Tips

- Small personal touches: Sprinkle freshly chopped parsley over the melted cheese right before serving for vibrant color.
Storage Instructions
- Refrigerator storage: Store leftover assembled subs in an airtight container for up to three days safely.

- Containers: Use glass meal-prep containers with secure lids to prevent any refrigerator odors.
