How to Make It
Preheat broiler to high.
Heat a large skillet over medium-high heat. Add oil; swirl to coat. Add onion, mushrooms, and garlic to pan; cook 7 minutes, stirring occasionally. Add chicken stock, artichokes, salt, pepper, tomatoes, and pasta to pan, and bring to a boil. Stir to combine. Cover; reduce heat, and simmer 8 minutes or until pasta is tender. Dot pasta mixture evenly with ricotta and mozzarella cheeses.
Place pan under broiler. Broil mixture 2 minutes or until cheese melts. Sprinkle evenly with basil.
