Can I make the meatballs ahead of time?
Yes. Form and refrigerate meatballs up to 24 hours before baking, or freeze them for up to 3 months. Add 2–3 minutes to baking time if cooking from frozen.
What's the best way to cook the meatballs?
Bake them at 400°F for 12–15 minutes until cooked through (165°F internal temp) rather than browning in a skillet, which saves time and reduces cleanup.
Can I use a different pasta shape?
Yes. Penne, rigatoni, or fettuccine work well. Avoid very thin pasta like angel hair, which may become mushy under the sauce.
How do I prevent the spinach from making the dish watery?
Use fresh spinach and add it just before serving, or squeeze thawed frozen spinach dry before stirring in to avoid excess liquid.
Can this be made ahead and frozen?
Yes. Assemble the bake, cover tightly, and freeze up to 2 months. Thaw overnight in the fridge and bake as directed, adding 10–15 minutes if needed.
