Love Spaghetti? It just got easier with this easy Instant Pot Spaghetti recipe. It’s made in one pot and is completely hands off. Tender spaghetti noodles in a meat sauce. Pair with a tossed salad and garlic bread for a complete meal.

I have finally fallen in love with my pressure cooker! I was the one that left it in the box and only made a few recipes like this Hamburger Stroganoff and Instant Pot Beef Taco Soup then stuck it away until I made the specific recipe again! That’s until I tried this Pressure Cooker Spaghetti recipe! It’s the BEST spaghetti I’ve ever had!
In fact I often times use whole wheat spaghetti and you know how sometimes whole wheat pasta is a bet “chewier” it totally comes out PERFECT with the pressure cooker! My family has no idea that I use whole wheat noodles most of the time! Win!
At first, I didn’t include the diced tomatoes, but I added them a few times ago and I love tomatoes in my spaghetti and it made me feel like I was eating at an Italian restaurant so I decided they are a must in this recipe. Now, if you’d like you can leave them out. You can also leave the hamburger out if you don’t like hamburger in your sauce.
I love hamburger in my sauce and when you cook the sauce, hamburger and pasta in the pressure cooker the flavor is unbelievable!

Easy peasy lemon squeezy. I had to add some homemade taco spice to the ground beef. But, otherwise, it was bomb-a-licious.

Have you ever subbed tomato’s sauce for spaghetti sauce? If so, did you add some extra seasonings to it? Which ones?

Jamie Johnson says
I used a can of tomato sauce instead of diced, as that’s all I had. Turned out so good. Not watery, but thick and saucy. So yummy!

Wondering if you have tested this recipe with any other pastas, say rigatoni, for example??
Julie Evink says
No I’m sorry I haven’t.
James says
Hello. I am thinking of making this. I loved the chicken Alfredo recipe.
Will this work with Penne pasta instead of spaghetti?
Julie Evink says
Yes I think that would work fine!
Amy Pletcher says
