How to Make Instant Pot Spaghetti Recipe

Step 1: Sauté the Aromatics

Start by setting your Instant Pot to the sauté function. Add olive oil to the pot and let it warm up before tossing in the diced onion. Cook until it becomes translucent, giving a sweet and mellow base. Then, stir in minced garlic, garlic salt, and Italian seasoning for just about 30 seconds to let those flavors bloom and fill the pot with irresistible fragrance.

Step 2: Brown the Ground Meat

Next up is the ground beef or turkey. Add it directly to the pot and break it apart as it cooks. Browning the meat not only imparts a rich, deep flavor but also makes sure every bite is packed with protein and juiciness. Once browned through, turn off the sauté function and, if needed, drain any excess fat — but leave a tablespoon or two behind to keep things flavorful.

Step 3: Deglaze and Layer

Pour in a splash of chicken broth to deglaze the pot, scraping up any tasty browned bits stuck at the bottom. These little bits are flavor gold! Then carefully lay the spaghetti noodles on top of the meat mixture, breaking them if needed and crisscrossing to fit them in without stirring. Pour the remaining chicken broth evenly around the noodles, then spoon over the marinara sauce and diced tomatoes. Press the noodles gently under the liquid so they’re fully submerged — this ensures even cooking during pressure.

Step 4: Pressure Cook

Lock the lid and set the steam release knob to sealing. Select the pressure cook (manual) setting and program it for 8 minutes. The Instant Pot will take a few minutes to come to pressure before it counts down, making this an almost hands-off step. The real magic happens here as the noodles soak up all those vibrant flavors and cook to tender perfection.

Step 5: Release Pressure and Rest

Once cooking is complete, turn off the Instant Pot and do a quick release by turning the steam release knob to venting. Carefully open the lid, then stir the spaghetti well to combine the sauce and noodles evenly. Let it rest for 5 minutes to absorb any excess liquids — this last step ensures the texture is just right and the flavors meld beautifully.

Garnishes

While this dish shines on its own, a sprinkle of freshly grated Parmesan cheese adds that finishing touch of creamy, salty richness. You can also add some chopped fresh basil or parsley for a burst of color and freshness that brightens the plate.

Side Dishes

Serve this spaghetti alongside a crisp green salad with vinaigrette or warm garlic bread to scoop up the sauce. Roasted vegetables like zucchini or broccoli also complement the hearty pasta and bolster the meal’s nutritional profile.

Creative Ways to Present

For a fun twist, serve portions in individual mini skillets or shallow bowls to impress guests with personalized presentation. You can also top with a fried egg or a drizzle of chili oil for a unique flavor spin that keeps this dish exciting every time.

Make Ahead and Storage

Storing Leftovers

Any leftover spaghetti can be stored in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen after sitting, making for an even tastier next-day meal. Just keep the sauce and pasta together to prevent drying out.

Freezing

This Instant Pot Spaghetti Recipe freezes exceptionally well. Portion it into freezer-safe containers or bags and freeze for up to 3 months. Thaw overnight in the fridge before reheating to preserve the texture and taste.

Reheating

Reheat leftovers gently in the microwave or on the stovetop over low heat. Add a splash of water or broth when warming to revive the sauce’s moisture and keep the pasta tender without getting mushy.
