If you’re new to the world of pressure cooking, this easy Instant Pot spaghetti and meat sauce is a terrific starter Instant Pot recipe to try. This was the very first dinner I made in the Instant Pot, and it was a huge hit with my family. One bite, and we were hooked!
Actually, Instant Pot jasmine rice was the first thing that I cooked in my new pressure cooker. I wanted to play it safe, so I chose an inexpensive side dish for the maiden voyage, so to speak. I just followed the recipe that was in the little booklet that came with the Instant Pot, and the rice was perfect — even better than the rice from our favorite Thai restaurant!
So after that win, I decided to try making spaghetti in the Instant Pot. Now personally, I’m kind of a pasta snob. And I’m usually picky about how I cook pasta, especially spaghetti.
But, I’m also all about quick an easy one pot dinners to feed the family. So after looking at what seemed like a billion recipes for Instant Pot spaghetti, I began experimenting.
I tried different amounts of pasta and different types and amounts of sauce until I was finally happy with the end result. And friends, I really, really recommend experimenting like crazy with Instant Pot recipes. What works for me may not work for you, so it may take several tries before you find that perfect spaghetti recipe — or any recipe, really!
Why this Recipe Works
But this recipe for Instant Pot spaghetti with ground beef definitely works for me, and I think you’ll like it, too! It’s simple, cooks in one pot, budget friendly and picky eater approved!
This time, I added a can of diced tomatoes after a reader told me she had done this with my Instant Pot creamy shells and beef recipe and loved the result. I used an entire 16 ounce box of spaghetti, and the liquid to pasta ratio was perfect.
I also tried using a little less than a whole box of spaghetti, and I got got the same result without using the diced tomatoes. Like I said, it’s all about experimenting.
How to Make Spaghetti in the Instant Pot
To make spaghetti and meat sauce the pressure cooker, just saute some lean or extra lean ground beef. Make sure no browned bits are sticking to the bottom — You can deglaze the pot with a little bit of water if you need to.
Layer the Spaghetti Strands
The trick to cooking spaghetti in the Instant Pot is to break the noodles in half and layering them in sort of a criss-cross pattern. This way, you can get them all under the liquid, and the noodles won’t clump together. Then, add your layered spaghetti, a jar of pasta sauce, the diced tomatoes and water.
How to Avoid the Burn Notice
You may have some spaghetti strands on the very top that stick a little, but they break apart easily once you stir everything up. I just fill up the empty jar of sauce with water and pour it all around the sides and middle of the tomato layer.
Then, I poke it a little with a spatula to make sure the water gets down through the layers and all the pasta is covered. Don’t stir it all together or it will be too thick, and you may get the burn notice.
After the pot comes to pressure, it takes just 5 minutes for the spaghetti to cook! I like to let the Instant Pot do a natural release for about 5 minutes, and then I release the steam, using a wooden spoon or cooking tongs — don’t want to risk any burns! And that’s it!
There are no messy stoves to clean up and only one pot to wash. Plus, everyone loves the texture of Instant Pot spaghetti!
