Here's how to make perfect Instant Pot Spaghetti two ways. You can make this with a classic meat sauce, or as a vegetarian dish, in under 30 minutes. It's the easiest one-pot meal!
16ouncesdry spaghetti noodles(regular or whole wheat; see gluten-free note)
4 1/2cupswater
1(25 oz.)jar marinara sauce
2 to 3tablespoonstomato paste(optional)
Vegetarian Version:
16ouncesdry spaghetti noodles(regular or whole wheat; see gluten-free note)
1/2cupdry red lentils(optional)
salt, to taste
5cupswater(use 1/2 cup less if you omit the lentils)
1(25 oz.)jar marinara sauce
2 to 3tablespoonstomato paste(optional)
Instructions
Meat Version:
Press the Sauté button and allow the Instant Pot to heat up. (This helps prevent sticking.) Drizzle a bit of olive oil into the bottom of the pot, and add the ground meat, salt, and oregano. Stir and break up the meat until it is browned and cooked-through. Drain any grease, if needed, then continue with the following directions, adding the noodles directly on top of the cooked meat. (Don't stir!)
Vegetarian Version:
Break the dry spaghetti noodles into thirds, so that they will easily fit into the Instant Pot. Add them to the pot in a criss-cross manner, so that they won't stick together and clump as they cook. (Remember, you can't stir the pot as they cook!)
If you would like to add lentils, pour them in as you add the spaghetti noodles. This is optional, so if you omit them, use only 4 1/2 cups of water for this recipe. I like to add a teaspoon of salt at this point, too, so the noodles will have a little extra flavor as they cook.
Pour the water over the noodles, then pour the jar of marinara sauce on top of that, covering as much of the top layer of noodles as you can. Add the tomato paste on top, if using, and don't stir.
Secure the lid, and move the steam release valve to Sealing. Use the Manual or Pressure Cook button on your machine to cook at high pressure for 3 minutes. It will take roughly 10-15 minutes for the Instant Pot to come to pressure, so when the floating valve in the lid pops up, that's when the cooking countdown will begin.
When the cooking is complete, allow the pressure to naturally release for 10 minutes. The screen will read LO:10. Move the steam release valve to Venting to release the remaining pressure. When the floating valve in the lid drops, it's safe to remove the lid.
Use tongs to stir the spaghetti, mixing the sauce throughout evenly. If the spaghetti looks a little watery at first, stirring the pasta will hellp the rest of the water absorb. Season to taste, and serve warm with your favorite toppings.
Leftover spaghetti can be stored in an airtight container in the fridge for up to 3 days.
