Cook 1 cup of dried pasta al dente according to package instructions and reserve some pasta water (about ½ cup) for later use.I cooked 1 cup of penne pasta with 1 cup of water and a pinch of salt for 1 whistle in a stovetop pressure cooker. Then, I let it rest for 5 minutes before quickly releasing the remaining pressure.You can also use an Instant Pot to boil the pasta. Pressure Cook (high pressure) for 4 minutes for al dente pasta. When the instant pot beeps, wait for 5 minutes and Quick Release the remaining pressure manually. Then, heat 1 teaspoon olive oil in a pan on medium flame and then add 3 garlic cloves along with 1 cup of thinly diced pumpkin, ½ cup diced tomatoes, 1 tablespoon pumpkin seeds, and salt. Sauté for a minute.
Add ½ cup of water (or vegetable broth), cover, and cook for 7-8 minutes, stirring occasionally, until the pumpkin is soft and mushy.
Once it cools down, add it to the blender along with ¼ cup of paneer (or cottage cheese, or tofu), ½ cup of water (or coconut milk, dairy milk). Blend to a smooth paste. Keep it aside.
Heat the pan, add the pumpkin pasta sauce, ¼ cup of reserved pasta water (or as needed), seasonings like 1 teaspoon Italian seasoning (or oregano), ½ teaspoon of red chili flakes, salt, and pepper to taste. Mix everything well, then reduce the heat and let it simmer gently for a minute.
Then add 1.5 cups of cooked penne pasta, toss everything well, and simmer for 1-2 minutes. Garnish with parsley or basil leaves. Serve the pumpkin pasta hot.
