This easy meatball casserole features juicy beef meatballs nestled in marinara sauce and topped with gooey mozzarella and parmesan cheese. It’s a cozy, crowd-pleasing dinner perfect for busy weeknights or family gatherings.
For best results, do not overmix the meatball mixture. Browning the meatballs before baking adds extra flavor but is optional. Use hand-grated cheese for better melting. You can assemble the casserole ahead and refrigerate up to 24 hours before baking. For gluten-free, use gluten-free breadcrumbs and check your marinara and cheese labels. Add ricotta for extra creaminess or veggies for more nutrition.
