I hope many of you might have tried my One-pot rice recipes in Instant Pot / Stove Top. If not please do try! I always felt, using Instant Pot Electric pressure cooker made my life, so easy, while making rice recipes.
But now, after preparing this, Spaghetti with homemade pesto sauce recipe in Instant Pot, I defy the above opinion to this new statement, Instant Pot is a boon not only to rice recipes but also in preparing such prolonged recipes, within 10 mins, even without using many utensils, when compared to Stove Top method.
Spaghetti (with any base sauce) is the easiest one-pot, filling meal that can be made in an Instant Pot / Pressure Cooker. It hardly takes 10 mins from start to finish. It comes under Quick Family Dinners for Weekdays.
This recipe is suitable for Vegetarian, Vegan, Plant Based diets but is not suitable for Nut free & Gluten free diets.

What is Spaghetti:
Spaghetti is a long, thin, string styled pasta which is the staple food of Italy. It is made either with whole wheat or from durum wheat semolina. Let me tell you that, it is pre-boiled in hot water, before being packed.
How to serve Spaghetti:
Spaghetti can be served as a main dish or even as a side dish. As you see in the below pic, I have served this Spaghetti in Pesto sauce as a main dish with Potato Fries. That made a completely filling meal.
Few other side dishes from my blog, suitable with this, Spaghetti with Pesto sauce:
- Potato Wedges – Rosemary (Air-Fryer & Oven)
- Potato Salad with Parsley (Instant Pot, Stove Top)
- Spicy Baby Potato Roast (Instant Pot / Stove Top)
- Sprouted Red Beans & Potato Salad (Instant Pot, Stove Top)

Possible alterations for ‘Spaghetti with Homemade Pesto Sauce’:
Sweet corn can be replaced with Frozen Green Peas, Canned / Boiled Chickpeas, Beans.
While I have used, Kale & Walnut Pesto Sauce (Dairy Free), you might use any other Pesto Sauce too. Even store bought Pesto sauce works well.
I have tried the same recipe with my homemade Kale Pesto Sauce and Basil Pesto sauce. The output was tasty both ways.
If you prefer more cheesy, feel free to add more as per your taste.
But if the quanity of the pesto sauce seems less, just remember that it might give bitter taste if too much is added.
Try to replace half the quantity of milk with cream, to get that thick & more creamy texture.
Vegan Options: Plant Based Vegan cheese, Mozerella cheese & Cheddar Cheese are the 3 varieties that I tried in 3 different instances for the same recipe. Tasted absolutely great with either of them.
This recipe is also tried by me with Coconut Milk, it was absolutely flawless.

STOVE TOP METHOD (15 to 20 mins):




INSTANT POT METHOD (8 to 10 mins):




Tips:
- The prepration time given above is related to preparing the fresh pesto sauce. If you are using store bought sauce, that prepration time doesn’t add up.
- You can even use any variety of Spaghetti for the same recipe.
- Any cheese of your choice is suitable here.
- Be very careful while boiling the spaghetti in water, so that it mustn’t turn sticky which spoils the entire texture of the dish.
- Don’t throw the water you get after draining the boiled spaghetti. You might use it for making the roti, paratha dough. I use it that way.
- You might even use the above boiled water, to loosen the spaghetti but at the same time can reduce the quanity of milk.
- To check for the spaghetti is cooked or not, just take a piece of it and press it in between your finger tips.
- For the stove top method: After boiling the spaghetti try to use as soon as possible, if not they might stick to each other.
- In case you do not have tongs, you can use two wooden ladles, one in each hand.
- If you have left overs eat at room temperature, but try not to reheat. Because the spaghetti becomes hard.
- Stove Top Pressure Cooker Method: Follow the same steps as of Instant Pot Method. But let it whistle only once. Remove the lid after the pressure is released.
Result:
- Spaghetti with Homemade Pesto Sauce, turned out very inviting to look at and was totally flavoursome bursting with the aroma from the freshly made Pesto.
- The cheese, milk made the entire dish creamy. Anyhow the perfectly cooked spaghetti is soft in texture.
- My kids had an extra serving of cheese on top of the spaghetti just after serving. They absolutely relished it!
