Preheat the oven to 350°F. Lightly grease a 2-quart baking dish and set it aside.

Heat a large skillet over medium heat. Add the Italian sausage and cook, breaking it into small crumbles as it browns. Once it's fully cooked and no pink remains, drain any excess grease.

Stir the marinara sauce, garlic powder, and Italian seasoning into the sausage. Reduce the heat to low and let the mixture simmer for about 5 minutes so the flavors can blend.

Transfer the sausage and sauce mixture to the prepared baking dish, spreading it into an even layer.

In a small bowl, mix together the ricotta and Parmesan cheese until combined. Spoon small dollops of the mixture evenly over the meat sauce.

Sprinkle the shredded mozzarella over the top. Bake for 15 minutes, or until the cheese is fully melted and the dip is hot throughout. Switch the oven to broil for 1 to 2 minutes, just until the cheese is bubbly and lightly golden. Watch it closely to prevent burning.

If you'd like, sprinkle a little extra Italian seasoning over the top before serving.

Serve warm with garlic bread, breadsticks, toasted baguette slices, crackers, or your favorite dippers.
