Turn the Instant Pot to sauté, add 2 teaspoons extra virgin olive oil to the inner pot, and let heat briefly ~60 seconds. Once the oil has heated, add 1 pound lean ground beef to the inner pot and brown it fully, breaking it up into small pieces as it cooks. Once the meat is cooked, turn off the pressure cooker. If needed, remove the inner pot, drain off any fat from meat, and return the inner pot to the Instant Pot.: The oil should shimmer and become fragrant within about 60 seconds, creating a slick surface that helps the meat brown evenly, you should hear a gentle sizzle when the extra virgin olive oil is hot. This brief heat step is important because it jumpstarts the Maillard reaction on the meat, building flavor. A common mistake is not letting the oil heat enough, which results in meat that steams instead of browns, so be patient and listen for the sizzle.
Pour a bit of the 4 cups low-sodium beef stock/broth to the inner pot and use a spatula or spoon to scrape up all the browned bits off the bottom of the inner pot. Add the remaining broth. *Adding a small amount makes it so you don't splash yourself when deglazing the inner pot.: As the 1 pound lean ground beef hits the hot oil, you will hear a louder sizzle and see the meat change from pink to brown, with some caramelized bits forming around the edges. Breaking the meat into small pieces increases surface area, maximizing browning and flavor. Browning takes on the order of a few minutes, and you should stop when no pink remains. Avoid crowding the pot, or the meat will steam and not develop the rich browned flavors you want.
Season with 1 tablespoon garlic powder, 1 tablespoon onion powder, 1 teaspoons paprika, 1 teaspoon kosher salt, 1/2 teaspoon black pepper, and 1 tablespoon Worcestershire Sauce to the inner pot and stir well to combine. Add 16 ounces elbow noodles and gently push them down into the sauce. You want the noodles just submerged in the liquid. Pour 8 ounces tomato sauce over the noodles, but do not stir!: At this point the aroma will be deeply savory, and the browned bits should be visible on the bottom. Turning off the unit prevents overcooking and allows you to assess if any excess fat needs removing. If you skip this pause and try to proceed immediately, you might mis-handle hot liquid or miss the chance to drain fat, which could make the dish greasy.
Place the lid on the pressure cooker, ensuring the venting knob is sealed/locked. Set to cook on high pressure for 3 minutes by hitting the manual or pressure cook button and adjusting the time by using the +/- buttons until the timer reads 3.: Draining excess fat will deliver a cleaner sauce and prevent a greasy mouthfeel; tilt the inner pot carefully and use a spoon or ladle. After draining, returning the pot ensures the browned fond stays where it belongs. A slip here is not draining enough, which leaves the final sauce heavy, so take an extra moment to remove visible fat if present.
Once the cooking time has elapsed, let the pressure release naturally for exactly 5 minutes. Then do a quick release of any remaining pressure, being sure to stand away from the vent knob when releasing pressure.: When the liquid hits those browned bits, you will hear a soft hiss and see them loosen as you scrape, releasing concentrated flavor into the broth, this is deglazing and it builds depth. Add a small amount first to avoid splashing hot liquid, and scrape thoroughly to prevent burn warnings later. If you rush this, the stuck bits can scorch during pressure cooking and cause error signals.
Remove the lid and fluff the noodles with a fork to incorporate everything. Taste, adjust seasonings if needed, and serve.: Pouring in the rest of the 4 cups low-sodium beef stock dilutes the concentrated deglazed bits into a flavorful base that will cook into the elbow noodles . Ensure the liquid reaches a level that will submerge the pasta when added. Not adding enough liquid risks undercooked noodles and a burn warning, so double check levels before sealing the lid.
Season with 1 tablespoon garlic powder, 1 tablespoon onion powder, 1 teaspoons paprika, 1 teaspoon kosher salt, 1/2 teaspoon black pepper, and 1 tablespoon Worcestershire Sauce to the inner pot and stir well to combine: You will smell the spices bloom as they hit the warm broth, creating an aromatic, layered base. Stirring distributes seasonings so every noodle absorbs flavor. One trap is adding too much salt early, remember the broth already contains sodium; taste at the end and adjust.
Add 16 ounces elbow noodles and gently push them down into the sauce: As you submerge the 16 ounces elbow noodles , you should see them soften and sink slightly, a visual cue they are ready for pressure cooking, and this placement ensures even hydration. Make sure the noodles are arranged flat and not standing on edge, so they cook uniformly. An error people make is stirring vigorously after this point which can cause noodles to clump or release too much starch, so just gently press them down.
You want the noodles just submerged in the liquid: Proper submersion means most of the noodle surface is covered while some may still peek out, ensuring even cooking under pressure. If too much noodle is exposed, parts will remain undercooked; if too much liquid covers them, the sauce may become thinner. Adjust carefully to strike the right balance.
Pour 8 ounces tomato sauce over the noodles, but do not stir: The 8 ounces tomato sauce will sit on top and meld during pressure cooking, giving color and acidity without making the liquid cloudy; visually you will notice a layer of red that integrates after cooking. Refrain from stirring to avoid settling starch at the bottom which can trigger a burn notice, a subtle step that protects both texture and function.
Place the lid on the pressure cooker, ensuring the venting knob is sealed/locked: You will hear a soft click when the lid locks and see the venting knob in the sealed position, signaling readiness. Proper sealing is essential for building pressure and cooking the noodles correctly. An often overlooked error is not checking the sealing ring or vent position, which can prevent the pot from pressurizing.
Set to cook on high pressure for 3 minutes by hitting the manual or pressure cook button and adjusting the time by using the +/- buttons until the timer reads 3: Once the pot reaches high pressure you will notice a change in the sound as steam becomes steady, and the timer will count down from 3 minutes, a very short cook time that finishes the noodles to tender perfection. Quick high pressure is what prevents the noodles from overcooking while still melding flavors. A mistake is setting too long a time which results in mushy pasta, so stick to the specified 3 minutes.
Once the cooking time has elapsed, let the pressure release naturally for exactly 5 minutes: Letting the pressure come down for 5 minutes allows the residual heat to continue cooking gently and absorb flavors, you might hear occasional soft pops as pressure eases. This brief natural release protects noodle texture from shock. Do not skip this window, as an immediate full quick release straight away can cause foaming or splatter.
Then do a quick release of any remaining pressure, being sure to stand away from the vent knob when releasing pressure: The remaining steam will hiss out rapidly during quick release, and you should feel a rush of warm, savory steam, so stand back and use a long handled tool if needed. This step finishes the pressure cycle safely. A hazard is leaning over the vent which can cause burns from the hot steam, so maintain distance.
Remove the lid and fluff the noodles with a fork to incorporate everything: When you lift the lid you will be greeted by steam and the rich aroma of sauce and meat, and fluffing the elbow noodles with a fork yields separated, saucy bites and distributes any concentrated salt pockets. If the texture seems slightly tight, a splash of reserved broth can loosen the sauce. Avoid over stirring vigorously which can break down noodles and make the dish gluey.
Taste, adjust seasonings if needed, and serve: The final step is sensory, taste for salt, pepper, and balance; add a pinch more kosher salt or a dash of black pepper if it needs brightening. Serve soon while warm for the best texture and mouthfeel. A common oversight is skipping the taste check, which can leave the dish under seasoned for your palate.
