Lasagna Saag Paneer

Step 1

Prepare the saag filling: Bring a large pot of water to boil then add the spinach. As soon as the greens fully wilt (about 2 minutes), strain through a colander and run cold water over the spinach to cool; wipe out and reserve the pot. Let the spinach drain before transferring to a blender. (There’s no need to squeeze any water out!)

Step 2

Add the tomatoes, serrano chiles, cilantro, kasoori methi (if using) and ¾ cup water to the blender with the drained spinach and blitz 30 seconds to 1 minute until puréed. Season to taste with salt; set the saag aside. (The filling may be made up to 2 days ahead and stored in the fridge in an airtight container.)

Step 3

In the same pot used for the spinach, melt the ghee over medium heat. Add the onion and sauté 6 to 8 minutes, stirring occasionally, until the onion is softened and somewhat golden. Add the garlic and ginger and continue to stir for 2 minutes, adjusting the heat as necessary to prevent any scorching.

Step 4

Add the chile powder, coriander, cumin and turmeric, and season with salt. Give it a good stir before adding the saag. Gently simmer and continue to stir occasionally, adjusting the heat as necessary if the mixture begins to sputter and splatter, until the saag is slightly thickened, 10 to 12 minutes. Remove from heat and set aside.

Step 5

Prepare the sauce: In a large pot, melt the butter over low heat. Add the flour and whisk until smooth. When the roux is golden in color, about 2 to 3 minutes, add the milk, adjust heat to medium and continuously stir until the béchamel thickens and coats the back of a wooden spoon, 5 to 8 minutes. Remove from heat and stir in the black pepper, nutmeg and ½ cup of the Parmesan. Whisk until smooth, season with salt and set aside. (The sauce may be made up to 2 days ahead and refrigerated. It might need to be loosened a little by adding some milk or water to the sauce before layering in the lasagna, as the sauce gets quite thick as it sits.)

Step 6

Assemble the lasagna: Heat the oven to 400 degrees. Grease a 9-by-13-inch baking dish that is at least 2 inches deep with 1 tablespoon oil. Pour in and spread enough sauce to cover the bottom of the dish. Layer noodle sheets on top of the sauce, breaking the noodles as needed to fit. (You may need 4 to 6 noodles per layer, depending on the size of the dish and the noodles you’re working with; you’ll need about 24 total.) Spread ⅓ of the saag over the noodles, then layer on ⅓ of the paneer shreds, followed by ¼ of the remaining sauce. Repeat this process 2 more times, starting with another layer of noodles (You will use all the saag and paneer.). To top the lasagna, add a final layer of noodles, spread the remaining sauce on the noodles and then sprinkle on the remaining ¼ cup Parmesan.

Step 7

Cover the lasagna with foil, lightly greasing one side so the foil doesn’t stick, and bake for 40 minutes, until the noodles are cooked through and the cheese has melted.

Step 8

Remove the foil and bake, uncovered, for about 20 minutes, until the lasagna is cooked through and is light golden on top. Let the lasagna cool for 15 to 20 minutes before slicing and serving. (Any leftover lasagna may be wrapped in foil and frozen for up to 3 months. Thaw overnight in the fridge before reheating in the oven.)
