Step-by-Step Instructions

1

Sauté aromatics and meat

Heat olive oil in the Instant Pot inner pot over sauté mode, add chopped onion and cook until translucent, then stir in minced garlic and cook for another minute. Add ground beef or sausage, breaking it up with a wooden spoon, and cook until browned and cooked through, draining excess fat if needed.

2

Build the sauce base

Stir in tomato paste and cook for one minute to deepen the flavor, then pour in crushed tomatoes and season with basil, oregano, red pepper flakes, salt, and pepper. Give everything a good stir so the spices and tomatoes are evenly coated.

3

Pressure cook the sauce

Lock the lid, set the valve to sealing, and pressure cook on high for 8 minutes. Allow the pressure to release naturally for 10 minutes, then quick release any remaining pressure to stop cooking.

4

Add spaghetti and cook

Open the lid, place broken spaghetti into the pot so it submerges as much as possible, and pour in chicken broth and soy sauce. Gently push pasta below the surface with a spoon if needed, but do not stir vigorously.

5

Pressure cook the pasta

Lock the lid, set the valve to sealing, and pressure cook on high for 1 minute with a natural release for 10 minutes, then quick release any remaining pressure.

6

Stir and separate the pasta

Carefully take out the inner pot and use tongs or two forks to gently lift and separate the spaghetti strands, stirring them through the sauce so every forkful is coated.

7

Check consistency and finish

If you prefer a thicker sauce, set the pot back to sauté mode and simmer for a few minutes while stirring, letting excess liquid reduce slightly.

8

Serve with cheese and herbs

Ladle steaming spaghetti and sauce into bowls, top with a handful of shredded mozzarella if using, and scatter fresh chopped parsley over the top for color and brightness.

9

Keep warm and enjoy

If you are not serving immediately, switch the Instant Pot to keep warm and give everything a gentle toss before ladling to loosen the sauce and keep the pasta from sticking.

Pro Baker Tips

✓Break the spaghetti to fit if your inner pot is smaller, and push the ends down carefully so they are fully submerged in the cooking liquid.

✓Taste and adjust seasoning at the end, adding a pinch of salt or extra red pepper flakes to match your family’s preference.

✓For a silkier sauce, mash a few cooked tomatoes against the side of the pot before pressure cooking.

✓Save leftovers for lunch the next day, as the flavors often deepen and taste even better after sitting in the fridge.

Storage & Serving Notes

◆Let the pot cool before securing the lid, then refrigerate in an airtight container for up to 3 to 4 days.

◆Reheat on the stovetop over medium low, adding a splash of water or broth to loosen the sauce, or use the pot-in-pot warm function if your Instant Pot has one.

Serving Suggestions

Frequently Asked Questions

Can I cook the pasta directly in the sauce in the Instant Pot?

Yes, by using the pressure cook function with enough thin liquid, the spaghetti will cook through and absorb flavor, just be sure to follow the liquid and time guidelines for your specific model.

What if I do not have an Instant Pot

You can make this on the stovetop by simmering the sauce for 20 to 30 minutes and then cooking the spaghetti separately in boiling salted water until al dente.

Is this recipe freezer friendly

Absolutely, cool completely, portion into airtight containers, and freeze for up to 2 to 3 months; reheat in the microwave or on the stovetop and add a little broth if the sauce has thickened too much.

How do I stop the pasta from turning mushy

Use the shortest pressure cook time, rely on a natural release for part of the cooking, and avoid overcooking, then drain any excess liquid and toss with sauce right away.
