Notes
- Pasta: Penne works great, but egg noodles or rotini hold the sauce just as well.
- Meat: Swap ground beef for ground turkey or Italian sausage if you like.
- Cheese: Use freshly shredded mozzarella for the best melt and flavor.
- Add veggies: Mushrooms, black olives, or red bell peppers are great extras.
- Add spice: Add red pepper flakes to the sauce or use hot Italian sausage instead of ground beef.
- Sauce: Marinara or pizza sauce both work—just go with what you prefer.
- Make ahead: Assemble everything, cover with foil, and refrigerate for up to a day before baking.
- Gluten-free: Just use your favorite gluten-free pasta and double-check that your marinara sauce and other ingredients are certified gluten-free.
Storage and Reheating Instructions
- Fridge: Let it cool completely, then transfer it to an airtight container. Store it in the refrigerator for up to 4 days.
- Reheat: To reheat, just pop it in the microwave or warm it in the oven until heated through. If frozen, thaw overnight in the fridge before reheating.
- Freeze: It also freezes well—wrap tightly in foil or use a freezer-safe container and freeze for up to 2 months.
