Preheat oven to 350°F.

Cook pasta in a large pot of salted, boiling water to al dente according to package instructions. Drain pasta.

In a large skillet, brown ground beef, diced onions, and garlic. Cook over medium high heat until the meat is no longer pink and the onions are tender.

Add one 24 oz. jar of marinara sauce to the meat mixture and simmer for 5 minutes.

In a medium mixing bowl, stir together the sour cream, ricotta, onion powder, garlic powder, and chives. Mix until combined.

Toss together the noodles and sour cream mixture.

In a 9x13 glass baking dish, layer half of the noodle mixture, half of the meat mixture, and ½ of the cheese. Repeat with a second layer.

Bake 20-25 minutes, or until the cheese is melted and beginning to brown.

Remove from the oven and serve immediately, garnished with a sprinkle of chives or parsley.
