We’ve developed this Instant Pot Spaghetti recipe with an option for those who want the quickest & easiest “dump-it-all-in meal”. You can get this spaghetti meal on the table (including getting up to pressure time) in 30 minutes! 😀
*Note: Simply remember to break the seasoned ground beef into smaller chunks, then layer the ground beef, onions, garlic, dried herbs at the bottom of the pot before pressure cooking.
Deglaze Instant Pot:
It’s super important to fully deglaze the bottom of the inner pot after browning or sauteing ingredients in the Instant Pot. This will prevent the dreaded “BURN” notice. Don’t worry! These are not burnt food debris. These caramelized brown bits will add flavor to your Instapot spaghetti.
Fully Submerge Spaghetti into Sauce: inevitably we need to break the dried spaghetti in half for them to fit in the Instant Pot. Try to spread out the spaghetti so they won’t clump together as they cook. Plus, it’s criticalto fully soak all the spaghetti into the cooking liquid to cook them evenly.
Don’t Mix the Spaghetti: Resist the urge to stir the spaghetti with the peeled tomatoes or marinara sauce because this may warrant the sensitive “BURN” notice.
Spaghetti Texture: we like al dente spaghetti, so the cooking time in this recipe is intended to cook the spaghetti till approximately 85% – 90% cooked. The spaghetti will continue to cook during the “sauce thickening” step, as well as by the residual heat. So, keep tasting and cooking (with the lid open) until the spaghetti reaches your preferred texture.
To prevent triggering Instant Pot’s sensitive “BURN” notice, it’s important to layer the ingredients in Instant Pot as directed in the recipe:
Ground Beef + Onion + Garlic at the bottom -> Chicken Stock -> Spaghetti -> Canned Tomatoes or Marinara Sauce on top (don’t mix after layering!)
Thicken & Season Spaghetti Sauce:
Don’t panic when you open the lid to a liquidy spaghetti sauce right after pressure cooking. That’s perfectly normal!
Thicken the spaghetti sauce by using the “Saute More” function, and bring the sauce back to a simmer. Use a few minutes to thicken, taste, and season the spaghetti and sauce to your preferences. These extra few minutes (plus extra few pinches of salt) will make a big difference to the spaghetti’s flavor & texture! 🙂

Brown Ground Beef in Instant Pot (Flavor Booster): Heat up Instant Pot using "Sauté More" function. Wait until it says "HOT" (~8 mins). Add 1 tbsp (15ml) olive oil in Instant Pot (ensure the oil is coated over the whole bottom).
Add 1lb (454g) ground beef in Instant Pot, then season generously with salt & ground black pepper. After browning for 5 minutes, discard the ground beef juice. Allow the ground beef to brown. Stir occasionally until they are slightly crisped (~5 – 7 mins). Taste then adjust with more salt & black pepper.
Saute Onion & Herbs: Add diced onions, minced garlic, 1.5 tsp (1.8g) dried basil, and 1.5 tsp (1.2g) dried oregano to the browned beef, then saute for another 2 minutes.
Deglaze Instant Pot: Pour 1 cup (250ml) unsalted chicken stock in Instant Pot, then deglaze by scrubbing all the flavorful brown bits off the bottom with a wooden spoon. Give it a quick mix.
Pressure Cook Spaghetti: Add 3 tbsp (45ml) regular soy sauce, 3 cups (750ml) unsalted chicken stock in Instant Pot. Break the 1 lb (454g) spaghetti in half, then add spaghetti in Instant Pot.
