You need a few basic ingredients to make vegan pumpkin pasta.
Pumpkin Puree: Follow my tips to make pumpkin puree at home from scratch or use the canned one. Do not use the pumpkin pie filling instead of puree.
Tomato Sauce: I use my homemade marinara style sauce.
Coconut Milk: Use coconut cream or milk instead of regular dairy-based products to make a luscious pumpkin sauce.
Vegetable Stock: It gives flavor to the sauce. Or use 1 stock cube dissolved in 1 cup warm water.
Fresh Herbs: From sage, thyme, rosemary, to fresh basil, you can pick either of these herbs to add in the pumpkin sauce.
Other Ingredients: Onion, Garlic, Salt, Olive Oil
Homemade Pumpkin Puree
Follow either the oven method or stovetop one to make smooth, luscious, flavorsome, and gluten-free pumpkin puree at home.
Oven Method: Pre-heat the oven at 180 degrees Celcius. Place the pumpkin slices in a baking tray. Place 2 – 3 sprigs of rosemary along with a whole garlic pod between pumpkin slices. Sprinkle salt and drizzle 2 – 3 tablespoons of extra virgin olive oil over the pumpkin slices.
Bake pumpkin for 20 minutes each side. Check using a fork, if the pumpkin flesh is tender. Baking time may vary, depending upon the size and variety of the pumpkin. So check after the first 20 minutes.
Once roasted, scoop out the flesh of the pumpkin. Discard the skin. Grind the roasted pumpkin pulp along with garlic cloves to a smooth puree.
Stovetop Method: Drizzle oil in a cast-iron skillet or a pan. Add pumpkin slices, season with salt, and crushed garlic. Cook on each side till fork tender. Discard skin, allow to cool, and later, blend to a smooth puree.
The Perfect Pasta Choice
My favorite ones are the penne and shell pasta. The sauce fills inside their shape making each bite of pasta so juicy.
Or the long thread-like pasta such as spaghetti, tagliatelle, or the fettuccine holds this rich pumpkin sauce perfectly.
Here are a few vegetables that can make your pumpkin pasta more wholesome, colorful, and fulfilling:
Spinach Leaves, Kale
Sauteed wild mushrooms
Cherry Tomato or sun-dried tomato
Roasted and diced butternut squash, zucchini
How To Make Pumpkin Pasta in Instant Pot
Making pumpkin pasta in an instant pot is a simple two-step process – Saute and Pressure Cook.
Saute Mode: Set the SAUTE Mode of IP for 5 minutes. Once the pot sets the timer, add olive oil, finely chopped garlic, and onion. Saute for 10 – 20 seconds. Next, add pumpkin puree, tomato sauce, salt, seasoning, and stir to mix.
Add coconut milk, vegetable stock, and uncooked pasta. Stir to combine. Taste, the liquid and add more seasoning if required.
Pressure Cook: Close the lid of IP. Set pressure valve to sealing position. Set PRESSURE Cook mode for 5 minutes. After the set time, release the steam manually, and open the lid. Add fresh herbs, and pumpkin pasta is ready to serve.
The best way to enjoy a creamy bowl of pumpkin pasta is with homemade focaccia bread and a light, leafy salad on the side.
