• Cook the pasta according to the package directions with enough water and salt, drain the water after the pasta is cooked. I recommend not cooking the pasta until very tender as we will bake this so it gets cooked again.
• Add a tablespoon of olive oil to the cooked pasta and mix well, so the pasta shells won't stick together, keep this aside.
• Wash the tomatoes and chop it in small sized pieces (we do not remove the seeds of the tomatoes here, you may also use fresh marinara sauce instead of preparing the tomato sauce from scratch).
• Heat 2 tablespoons of olive oil in a pan and add the chopped tomatoes.
• Add the salt, garlic powder and crushed ginger, saute for  2 to 3 minutes.
• Add the chopped cilantro leaves and dried oregano flakes, saute for another 2 to 3 minutes in medium heat.
• As the tomatoes get cooked, you can see that the tomato pieces turns soft and the fresh sauce is formed which combines with the flavor of the spices and cilantro leaves.
• Cook the tomato sauce for another few minutes until the sauce starts separating from the oil.
• Add the prepared tomato sauce to the cooked pasta, mix everything well so the sauce will mix up with the cooked pasta shells. Keep this aside closed.

To prepare the mushrooms

• In a pan, heat the butter and add the mushrooms.
• Saute the mushrooms for 2 to 3 minutes and the you can see the mushrooms will start releasing the water content.
• Reduce the heat, add salt and more garlic powder (extra 2 teaspoons of garlic powder) and cook in low heat for another 3 to 4 minutes.
• Add the 2 to 3 tablespoons of whole milk to the mushrooms and mix well, cook in low heat for another 2 minutes, stirring frequently so the milk won't burn at the bottom of the pan.
• Transfer ¾th of the prepared mushrooms to the cooked pasta in sauce, stir everything well so the roasted mushrooms gets mixed up well with the cooked pasta in sauce.

To bake the pasta

• Prepare a baking pan (a casserole dish would work well) and transfer the pasta to the baking pan.
• If you are using cheese, you may add a layer of pasta to the pan, add a layer of shredded cheese and then add the remaining half of pasta in another layer.
• Now top the pasta with the remaining ¼th of roasted mushrooms in a single layer.
• Preheat the oven to 350 degree Fahrenheit.
• Bake the mushroom pasta for 2 5 to 30 minutes or until the top of the pasta starts to turn light golden brown in color.
• At this point, you may add a little more shredded cheese on top and bake for another few more minutes if desired.
• Serve the delicious baked mushroom pasta for a delicious vegetarian lunch or dinner!
