Ingredients Needed
- 1 lb / 450g frozen beef meatballs Look for ones without heavy breading for better texture.
- 16 oz / 450g dry penne pasta Penne holds the sauce inside its hollow center perfectly.
- 24 oz / 680g marinara sauce Use your favorite brand; if it’s thick, add a splash of water.
- 4 cups / 950ml beef broth Low-sodium versions give you more control over the saltiness.
- 2 cups / 225g shredded mozzarella cheese Freshly grated melts way smoother than the bagged stuff.
- 1 tsp / 2g dried oregano Rub it between your palms to release the hidden oils.
Essential Equipment
You just need a deep 9×13 baking dish to keep everything contained. I prefer ceramic because it holds heat beautifully (plus, it looks nice on the table). Heavy-duty foil is non-negotiable for trapping that vital steam.

Tips for Success
If the sauce looks too thin, don’t panic; the pasta will absorb the liquid. Keep your foil tight so steam doesn’t escape. If you’re nervous about dryness, add an extra half-cup of broth. Trust the process.
Variations & Substitutions
- Go gluten-free by swapping in your favorite GF penne.
- Make it dairy-free by using a vegan mozzarella-style shreds.
- Boost the fiber by tossing in a handful of fresh spinach before the final bake.
Serving Suggestions
Pair this with a bright, vinegary green salad to cut through the richness. Some warm garlic bread is also essential for mopping up the leftover sauce. A crisp iced tea makes for a perfect non-alcoholic companion.
Health Benefits
- Provides a solid dose of protein for muscle repair.
- Beef broth adds essential minerals like iron and zinc.
- The tomatoes offer a nice boost of lycopene for heart health.
Storage & Reheating
Keep leftovers in an airtight container for up to 3 days. When reheating, add a splash of water to the pan to revive the sauce. Cover and bake at 350F until warmed through.
