Instructions
Step 1: Prepare the Oven
Preheat your oven to 375°F (190°C).
Line a baking sheet with parchment paper or aluminum foil for easy cleanup.
Step 2: Cook the Spaghetti
Bring a large pot of salted water to a boil.
Cook the spaghetti according to the package directions until al dente.
Drain thoroughly and set aside.
Step 3: Prepare the Meat Sauce
Heat a large skillet over medium heat.
Add the ground beef and cook until browned, breaking it into small crumbles as it cooks.
Drain any excess grease.
Stir in:
- Prego spaghetti sauce
- Italian seasoning (if using)
Simmer for about 5 minutes.
Step 4: Combine
Add the cooked spaghetti to the meat sauce.
Toss until every strand is coated with the rich sauce.
Step 5: Prepare the Rolls
Slice each sub roll lengthwise without cutting all the way through.
Remove a little of the soft bread from the center to create room for the filling.
Brush the inside of each roll with melted butter.
Sprinkle evenly with the garlic seasoning.
Step 6: Fill the Subs
Spoon a generous amount of the spaghetti mixture into each roll.
Top generously with:
- Mozzarella cheese
- Parmesan cheese

- Caesar salad
- Garlic bread

Recipe Notes
- Bakery-style rolls hold up best to the hearty filling.
- Toasting the bread with butter helps prevent sogginess.
- Freshly shredded mozzarella melts more smoothly than pre-shredded cheese.
- Let the subs cool for 2–3 minutes before serving to help the filling set.
Helpful Tips
- Cook the spaghetti just until al dente to prevent it from becoming too soft after baking.
- Drain the beef well to keep the subs from becoming greasy.
- Don’t overfill the rolls, as the filling can spill out during baking.
- For extra crispy bread, toast the rolls for 3–4 minutes before filling.
- Add extra Parmesan just before serving for even more cheesy flavor.

Frequently Asked Questions
Can I use another pasta?
Yes. Thin spaghetti, angel hair, or fettuccine all work well, though classic spaghetti is the easiest to fill into the rolls.
Can I substitute the ground beef?
Absolutely. Ground turkey, ground chicken, Italian sausage, or plant-based crumbles are great alternatives.
Can I prepare these ahead of time?
Yes. Assemble the subs, cover, and refrigerate for up to 24 hours before baking.
What cheese works best?
Mozzarella provides the classic stretchy melt, while Parmesan adds a rich, savory flavor. Provolone or an Italian cheese blend also work well.
Can I make these in an air fryer?
Yes. Air fry at 350°F (175°C) for 5–7 minutes, or until the cheese is melted and the bread is toasted.
How do I prevent soggy rolls?
Lightly toast the rolls and avoid adding excess sauce. Removing a little of the soft bread from the center also helps.
What can I serve with these subs?
They pair wonderfully with salad, fries, roasted vegetables, soup, or potato wedges.
