Step 1

Cook vermicelli according to package directions; drain. Rinse with cold water; drain again.

Step 2

Meanwhile, in a large skillet heat butter over medium-high heat until melted. Add 1/2 cup onion; cook about 4 minutes or until onion is tender, stirring occasionally. Add lemon juice, ginger-garlic paste, 2 teaspoons garam masala, 2 teaspoons cumin, and chili powder; cook and stir for 1 minute. Carefully add tomato puree; cook and stir for 2 minutes more. Stir in yogurt, whipping cream, salt, and cayenne pepper. Stir in chicken. Cook, uncovered, over low heat for 10 minutes, stirring frequently.

Step 3

In a large bowl combine three-fourths of the paneer, the cream cheese, 1 teaspoon garam masala, 1 teaspoon cumin, and turmeric. Stir in spinach.

Step 4

Preheat oven to 350°F. Butter a 3-quart rectangular baking dish. Transfer half of the chicken mixture to the prepared baking dish. Top with half of the vermicelli; spread evenly with spinach mixture. Top with the remaining vermicelli and the remaining chicken mixture.

Step 5

Bake, covered, for 65 to 70 minutes or until heated through. Sprinkle with the remaining paneer. Bake, uncovered, for 5 minutes more. If desired, sprinkle with green onions.
