Step 1: Prepare the Meatballs
Place the lean ground beef in a large mixing bowl.
Add the grated onion, minced garlic, oregano, basil, paprika, salt, and black pepper.
Mix gently until the ingredients are evenly combined, taking care not to overwork the meat.
Shape the mixture into approximately 16 evenly sized meatballs.
Step 2: Brown the Meatballs
Lightly spray a large non-stick frying pan with cooking spray and heat over medium-high heat.
Add the meatballs in batches and cook for approximately 5–6 minutes, turning occasionally until browned on the outside.
They do not need to be fully cooked at this stage because they will finish cooking in the oven.
Transfer the browned meatballs to a plate.
Step 3: Cook the Aubergine
Add the diced aubergine to the same pan with a little additional cooking spray.
Cook for 5–7 minutes, stirring occasionally, until the aubergine begins to soften and develop a lightly golden color.
Remove from the pan and set aside.
Step 4: Make the Marinara Sauce
Reduce the heat to medium and add the chopped onion.
Cook for approximately 4 minutes until softened, adding a splash of stock if necessary to prevent sticking.
Stir in the minced garlic and cook for another minute.
Add the chopped tomatoes, tomato purée, remaining stock, oregano, basil, and smoked paprika.
Season with salt and black pepper.
Stir well and simmer gently for 8–10 minutes, allowing the sauce to begin thickening.
Step 5: Assemble the Meatball Bake
Preheat the oven to 200°C (180°C fan) or 400°F.
Spread the cooked aubergine evenly across the bottom of a medium-sized ovenproof baking dish.
Arrange the browned beef meatballs over the aubergine.
Pour the marinara sauce over the meatballs, making sure everything is well coated.
Step 6: Add the Mozzarella
Sprinkle the grated reduced-fat mozzarella evenly over the meatballs and sauce.
Finish with a little dried oregano if desired.
Step 7: Bake Until Golden
Transfer the dish to the preheated oven.
Bake uncovered for approximately 15–20 minutes, until the sauce is bubbling, the cheese has melted, and the meatballs are cooked through.
For a more golden topping, place the dish under the grill for 1–2 minutes, watching carefully to prevent burning.
The meatballs should reach an internal temperature of 71°C (160°F).
Step 8: Garnish and Serve
Remove the baking dish from the oven and allow it to rest for 5 minutes.
Sprinkle with freshly chopped parsley or basil.
Serve warm with your favorite side dishes.
Tips for the Best Beef Meatball Marinara Bake
Choose extra-lean beef. Ground beef containing 5% fat or less provides plenty of flavor while keeping the dish relatively light.
Avoid overmixing the meatballs. Mixing the ingredients too vigorously can create a dense texture.
Brown before baking. Browning the meatballs adds flavor and helps them hold their shape.
Cook the aubergine first. Softening the aubergine before baking ensures it becomes tender and blends into the sauce.
Use reduced-fat mozzarella. It creates a delicious cheesy topping while keeping the added fat lower than regular full-fat mozzarella.
Allow the sauce to thicken. If your tomatoes release a lot of liquid, simmer the sauce a little longer before assembling the bake.
