Assembly:

Directions: 

  1. Pink sauce:

    • In a pan on medium heat add olive oil/butter.

    • Add onion chopped and garlic sliced. Cook for 6-7 mins till it starts browning.

    • Add tomato paste and cook for 3-5 mins.

    • Add Oregano, Red chili flakes, Salt And Pepper, Sugar and ajwain or nutmeg.

    • Add tbsp flour and cook it well for 3-5 mins to remove the raw taste.

    • Add milk in 2 additions and use a whisk to stir and prevent any lumps.

    • Add cream and mix well. Cook for 3-4 mins till it starts thickening.

    • Add cheese and mix well. Cook for 3-4 mins till it’s thickened. Add water if you aren’t pre boiling sheets to make it more liquid.

    • Sauce is ready!

    • Add chopped mushrooms and cook for 7-8 mins. Cook till it releases water and half of the water has gone.

    • Add corn kernels and mix it well.

    • Add pesto and ricotta and mix. Cook for 4-5 minutes till most of the water from ricotta cooks.

  3. Assembly:

    • Use an oven safe baking dish. I used a 9*15 inch dish.

    • If you are using pre boil lasagna sheets, boil them and keep.

    • On the base, spread a little of pink sauce just to cover the bottom.

    • Top with lasagna sheets.

    • Layer 1/3rd of the mushroom filling over it.

    • Spread a thin layer of the pink sauce over it and then repeat the layer two more times, ending with lasagna sheets.

    • End with a layer of pink sauce over it all. Make sure it covers the lasagna sheets well.

    • Top with shredded cheese.

    • The lasagna is layered.

  4. Cooking lasagna:

    • Easy bake lasagna sheets: If you are using easy bake lasagna sheets, preheat the oven to 350 F. Cover the dish with a foil paper and bake for 1 hour at 350F. Remove the foil and bake at 375 F for 15-20 mins till the cheese is golden brown and lasagna sheets are cooked through.

    • Pre-boiled lasagna sheets: If you are using easy bake lasagna sheets, preheat the oven to 375 F. Bake at 375 F for 20-25 mins till the cheese is golden brown and the lasagna is cooked through.

    • Frozen Lasagna: Thaw for 15-20 mins on the counter. Cooking time will increase by about 20-30 mins. (for easy bake sheets, the time increase is at 350 F)

    • Once out of the oven, let it sit for 5-10 mins and then serve. This helps the lasagna set and flavors marinate better.

    • Slice and serve!

Notes/Tips:

  • You can make the pink sauce and keep it in the fridge, 3-4 days before.

  • You can also make the filling a day before and keep it.

  • You can layer and assemble the lasagna and freeze it for 2-3 months.

  • If you are freezing it, thaw it for 15-20 mins on the counter. Cooking time will increase by about 20-30 mins. (for easy bake sheets, the time increase is at 350 F)

  • If you have the option, use easy bake lasagna sheets. I prefer the end result, it cooks in the sauce and makes it more flavorful.

  • Make sure you cover the dish (when using easy bake sheets) with foil while baking. This helps the sheets cook as it traps the heat.

  • The extra water in the pink sauce for easy bake lasagna sheets helps the sheets cook in the oven.
