Make-Ahead Tips
This cozy spaghetti casserole is perfect for busy families! You can prep it up to 24 hours before baking – just keep it covered in the fridge. Let it sit at room temperature for 30 minutes before popping it in the oven. Want to freeze it? Assemble everything except the top layer of cheese, wrap tightly, and freeze for up to 3 months. When ready to eat, thaw overnight in the fridge, add the cheese, and bake!
Simple Swaps
Feel free to mix things up with this flexible recipe! Try ground turkey instead of beef for a lighter version. Not a fan of cottage cheese? Ricotta works beautifully too. You can swap the spaghetti for any long pasta like linguine or fettuccine. For extra veggie goodness, add finely chopped carrots, celery, or bell peppers when cooking the onions.
Serving Ideas
This cheesy baked spaghetti shines with simple sides! Pair it with a crisp green salad and warm garlic bread. Want to dress it up? Sprinkle fresh basil on top just before serving, or offer extra warm marinara sauce on the side. Remember to let it rest for those important 15 minutes – this helps the layers stay put when you cut into it!
Storage & Reheating
Lucky enough to have leftovers? Cover and keep them in the fridge for up to 4 days. To reheat, pop individual portions in the microwave for 1-2 minutes. For best results, add a splash of marinara sauce before reheating to keep it nice and saucy. The pasta might soak up some sauce as it sits, but it’ll still taste amazing!
