In a large mixing bowl, combine the ricotta cheese, ground beef or turkey, breadcrumbs, grated Parmesan cheese, egg, minced garlic, dried oregano, fresh basil, salt, and black pepper. Mix the ingredients until well combined.
Preheat your oven to 375°F (190°C).
Using your hands, form the mixture into meatballs, about 1.5 inches in diameter. You should get around 20 meatballs.
Heat a skillet over medium heat and add a drizzle of olive oil. Once hot, add the meatballs in batches, being careful not to overcrowd the skillet. Brown the meatballs on all sides, about 5-6 minutes per batch.
In a large baking dish, spread half of the marinara sauce on the bottom. Carefully place the browned meatballs over the sauce, then pour the remaining marinara sauce over the top.
Cover the baking dish with aluminum foil and bake in the oven for 20 minutes. Remove the foil and bake for an additional 10 minutes, or until the meatballs are cooked through (internal temperature should reach 160°F or 70°C).
Once done, remove from the oven and let it cool for a few minutes. Garnish with chopped parsley before serving.
Notes
You can substitute ground turkey for a lighter option.
