Why You’ll Love This Recipe
- All-in-one convenience: Meat, sauce, and pasta cook together — fewer dishes to wash and no mess on the stovetop.
- Fast comfort food: From start to finish, dinner’s ready in under 30 minutes. Winning!
- Kid-friendly: My family devours it, and no one complains about onions when they’re cooked right into the sauce.
- Perfect for busy nights: Ideal for harvest, 4-H meeting nights, or when you just can’t face the question, “What’s for dinner?” one more time.
Ingredients
- Lean ground beef: I use lean beef to keep things lighter, but you can easily swap in ground turkey, ground pork, ground venison or Italian sausage if that’s what’s in the fridge.
- Onion and garlic: Fresh is best, but if you’re short on time, a sprinkle of onion powder and garlic powder does the trick.
- Olive oil: Helps brown the meat and prevents sticking.
- Dry spaghetti: Break your spaghetti noodles in half to help them fit in the pot and cook evenly.
- Marinara Sauce: Use your favorite sauce, spaghetti sauce or homemade sauce — whatever you have in your pantry will work just fine.
- Water: You’ll need about 2 cups of water (or slightly more if using a thicker tomato sauce) to create steam for pressure cooking.
- Seasonings: Salt, black pepper, and Italian seasoning give this simple meat sauce recipe a deliciously savory flavor.
Tip: It's easy (and economical) to make your own homemade Italian seasoning.
How to Make Instant Pot Spaghetti
- Step 1: Brown the meat: Turn your Instant Pot to Sauté mode. Add olive oil, then the lean ground beef. Break it up as it cooks, about 4–5 minutes.
- Step 2: Build the sauce: Toss in diced onion and garlic; sauté another minute or two until fragrant. (If using garlic powder or onion powder, sprinkle it in here.) Press Cancel to turn off Sauté.
Use a wooden spoon to scrape up any brown bits from the bottom of the pot. This step helps prevent a burn warning later.
- Step 3: Layer the noodles: Spread the spaghetti over the meat in a criss-cross pattern — this is the key for perfect spaghetti that doesn’t clump together.
- Step 4: Add the sauce and liquid: Pour the marinara sauce and the 2 cups of water right over the top. Sprinkle with salt, pepper, and Italian seasoning. Don’t stir! (This helps prevent burning on the bottom of the pot.)
Pressure cook: Lock the lid, set the valve to Sealing, and cook on High Pressure for 8 minutes.

- Step 5: Natural release: When the cook time ends, allow the pressure to naturally release for 10 minutes (that just means leave it alone). After 10 minutes, carefully turn the valve to Venting to release any remaining pressure.
Stir everything together — the noodles will soak up the sauce as it rests. If you see a little grease on top, just give it a good stir to mix it back in.
- Let it sit for a minute or two before serving to thicken slightly.
Variations
- Skip browning ground beef and instead nestle in frozen or homemade meatballs under the sauce before cooking. The rest of the steps stay the same.
- Mix in ½ cup shredded mozzarella or Parmesan right after cooking for a thicker, cheesier sauce.
- If you like it creamy, stir in 2–3 tablespoons of cream cheese or a splash of heavy cream after cooking.
Serving Suggestions
Top your pasta with freshly grated Parmesan or a sprinkle of nutritional yeast if you’re dairy-free. Round it out with garlic bread, a green salad, or some steamed vegetables for balance.
For a veggie boost, stir in a handful of frozen spinach or peas after cooking — they’ll thaw right into the homemade sauce and add color and nutrients to your quick family dinner.
Storage & Reheating Tips
To store: Let leftovers cool completely, then transfer to an airtight container. Store in the fridge up to 4 days.
To reheat: Microwave in 1-minute bursts, stirring halfway through, or warm gently on the stovetop with a splash of water to loosen the sauce.
To freeze: Not recommended — cooked pasta tends to lose texture once thawed.
This recipe fits perfectly in a 6-quart Instant Pot, though you can double it in an 8-quart model as long as you don’t go over the fill line.
Instant Pot Tip
Be sure to deglaze the bottom of the pot before pressure cooking to remove those flavorful brown bits and avoid the dreaded burn warning.

Apart from the missing meatballs, I'm going to make it in my new instant pot. I guess could make meatballs separately.
