Twenty meatballs, one dish, forty-five minutes. That's the whole promise here. You sear them on the stove, drown them in marinara, cover them in mozzarella, and let the oven finish the job.
The meat is half ground beef, half hot Italian sausage. The sausage is what gives it the kick, so don't swap it for plain pork unless you want a milder bake. Bread crumbs, eggs and milk go in to keep the meatballs soft instead of bouncy.
The one thing that goes wrong is skipping the sear. Raw meatballs dropped straight into sauce fall apart and turn gray. Two or three minutes a side in a hot pan fixes that before the oven ever sees them.
Step-by-Step Instructions
1. Heat the oven and mix
Set the oven to 425°F. In a big bowl, put the beef, sausage, garlic, parsley, parmesan, salt, pepper, bread crumbs, eggs and milk. Work it together with your hands until no dry crumbs are left.
2. Roll the meatballs
Scoop and roll into balls about 4 to 5 ounces each. A medium ice cream scoop keeps them the same size so they cook at the same rate.
3. Sear both sides
Heat the olive oil in a pan over medium heat. Brown the meatballs for 2 to 3 minutes a side until they have a dark crust. They'll still be raw in the middle, and that's fine.
4. Build the dish
Spread a few tablespoons of marinara across the bottom of a casserole dish. Set the meatballs in, pour the rest of the jar over them, and scatter the mozzarella on top.
5. Bake covered
Cover the dish with foil and bake at 425°F for 25 minutes. The cheese should be fully melted and the meatballs cooked through.
6. Garnish and serve
Scatter the reserved parsley over the top and serve straight from the dish.
How to Store Cheesy Meatball Bake
Refrigerator
Keep leftovers in a sealed container for up to 4 days. Cool them within 2 hours of baking.
Freezer
Freeze baked meatballs with the sauce for up to 3 months. Freeze the cheese-topped bake in a foil pan before baking if you want to cook it later from frozen, and add 15 to 20 minutes to the bake time.
Reheating
Reheat covered at 350°F until the center of a meatball reads 165°F. A microwave works for single portions but the cheese goes soft rather than stretchy.
Tips & Tricks
- A medium ice cream scoop gives you even 4 to 5 ounce meatballs without weighing anything.
- Mix with your hands just until everything comes together. Overworking the meat makes the meatballs tough.
- Spread a few spoonfuls of sauce on the bottom of the casserole dish before the meatballs go in. It keeps them from sticking and starts the sauce layer.
- Cover with foil for the bake. Without it, the cheese browns before the meatballs cook through.
Variations
No Sausage Version
Use 2 lbs of ground beef and add 1 teaspoon of red pepper flakes for some heat. The bake still works, it just tastes milder.
Mild Batch
Swap the hot sausage for sweet Italian sausage if kids are eating.
Extra Sauce
Keep a second small jar warm on the stove for spooning over at the table. The bake itself only uses the 24 ounces.
Frequently Asked Questions
Q: How do I know the meatballs are cooked through?
Use an instant-read thermometer in the center of the largest one. Ground beef and pork should hit 160°F. Color alone won't tell you.
Q: Can I make this ahead?
Yes. Roll and sear the meatballs a day ahead, then keep them covered in the fridge. Assemble the dish and bake it the day you're serving.
Q: Do I have to sear them first?
You don't have to, but the sear is what holds the shape and gives the outside some texture. Raw meatballs in sauce tend to break apart.
Q: Can I use frozen meatballs instead?
You can, but the timing changes. Frozen meatballs need longer in the oven, so follow the package directions and check the center with a thermometer.
Q: What do I serve with it?
Crusty bread, pasta, or a pile of greens. The sauce is the best part, so something to soak it up makes sense.
