Turn your Instant Pot onto saute mode. Add the ground beef, breaking it up with a sturdy spatula as it cooks. Cook until completely browned. Hit the cancel button to turn the pot off.
Add all of the seasonings plus the broth, stirring until evenly combined, and scraping up any browned bits off the bottom of the pot liner as you go.
Break the dried pasta in half, then divide it into two parts. Add the first half of the halved pasta to the pot, but try to lay it out in three sections. It should be on top of each other but fanning out. This fanning out will prevent clumping/sticking while cooking. Repeat with the remaining pasta. The more different directions the pasta groups are splayed out in- the better!
Pour the pasta sauce evenly out over the pasta, but DO NOT stir.
Add the lid, turning to close, and set the vent valve to the sealed position. Cook the spaghetti for 7 minutes at high pressure.
When the pot beeps to indicate cooking's done, carefully perform a controlled quick release. Once the pin's dropped, open the lid and remove.
Stir the pasta, and do not be worried about the remaining liquid. Let the stirred pasta rest for a few minutes and it will absorb it.
Let the pasta mixture rest 3-5 minutes, before serving.
Top with your favorite spaghetti garnishes and enjoy!
