10 Minute Instant Pot Spaghetti

When dinner needs to happen fast but you still want big, comforting flavor, this 10 Minute Instant Pot Spaghetti is the answer. It delivers saucy, perfectly cooked noodles and savory beef in a fraction of the time it takes on the stove — all in one pot. This recipe uses simple pantry staples and an Instant Pot to keep cleanup minimal and the results impressive. Read on for tips, tricks, and the step-by-step method to make dinner tonight a breeze.

Why this recipe works

There are two smart ideas at play here. First, cooking the ground beef briefly before adding liquid builds savory depth. Second, the pressure-cooking step allows the spaghetti to cook quickly and evenly in the sauce and water. The result: tender pasta that soaks up flavor without becoming mushy, and a rich tomato-beef sauce that’s ready in about 20 minutes start to finish — with only 10 minutes of high-pressure cooking time.

Ingredients

• 1 tablespoon olive oil
• 1 pound lean ground beef
• 1 tablespoon Italian seasoning
• 1 teaspoon garlic powder
• ½ teaspoon salt
• ¼ teaspoon ground black pepper
• 1 pound uncooked spaghetti noodles
• 2 (24-ounce) jars marinara sauce
• 3 cups water

Equipment

• 6-quart (or larger) electric pressure cooker/Instant Pot
• Long tongs or a wooden spoon
• Measuring cups and spoons
• Large heatproof bowl for resting, if desired

Prep tips before you start

Have everything measured and nearby so the cook time stays tight. Break the spaghetti noodles in half if your pot’s diameter makes it hard for long noodles to lay flat; they’ll cook the same either way. Use a lean ground beef to keep the sauce from becoming greasy, and choose a good-quality marinara — it’s the backbone of this one-pot meal. Lastly, keep your Instant Pot lid and steam release clean and functioning for a smooth pressure release.

Step-by-step Instructions

Follow these clear steps in order. The directions have been rewritten for clarity while keeping the ingredient amounts and overall sequence the same as the source.

1. Sauté the beef: Set the Instant Pot to the “Sauté” function and pour in 1 tablespoon olive oil. When the oil is hot and shimmering, add 1 pound lean ground beef. Break the beef into pieces with a spoon or spatula so it cooks evenly.
2. Cook until mostly browned: Continue sautéing the beef, stirring occasionally, until it is mostly browned. You do not need it to be fully crisped, but most of the pink should be gone.
3. Season the meat: Sprinkle 1 tablespoon Italian seasoning, 1 teaspoon garlic powder, ½ teaspoon salt, and ¼ teaspoon ground black pepper over the almost-browned beef. Stir thoroughly so the seasonings coat the meat and combine with any browned bits in the pot.
4. Turn off sauté: Press “Cancel” on the Instant Pot to stop the sauté function so you can safely add the rest of the ingredients.
5. Add the noodles: Place 1 pound uncooked spaghetti noodles into the pot. Arrange them in a crisscross or broken-in-half pattern so they fit; this helps avoid clumping and makes sure the noodles are submerged later.
6. Pour in marinara sauce: Pour the contents of 2 (24-ounce) jars marinara sauce evenly over the noodles. Use a spoon to coax sauce down between strands so more of the noodles are coated and covered.
7. Add water: Pour in 3 cups water on top of the sauce and noodles. Do not stir vigorously — you want the liquid to settle around the noodles and sauce rather than creating a frothy layer that could trigger the pressure sensor.
8. Secure the lid: Close and lock the Instant Pot lid. Make sure the steam release valve is set to the “Sealing” position.
9. Pressure cook: Set the Instant Pot to high pressure for 10 minutes. Because the pot must come to pressure before the countdown begins, the total time will be slightly longer than 10 minutes, but the actual high-pressure cooking step is 10 minutes.
10. Quick release and check: When the cooking cycle finishes, carefully switch the steam release valve to “Venting” for a quick release. Once the pressure is fully released and the lid can be unlocked, open the pot. Give the spaghetti a gentle stir to combine the sauce and check the texture. If any noodles are still a touch firm, allow the pasta to rest in the hot sauce for a couple of minutes — the residual heat will finish them without overcooking.

Finishing touches

Taste and adjust seasoning, adding a pinch more salt or a crack of black pepper if needed. If the sauce feels a little thin, simmer briefly on the “Sauté” setting to reduce it down a minute or two, stirring constantly to prevent sticking. Serve hot with a sprinkling of grated cheese or a drizzle of good olive oil if you like.

Serving suggestions

This 10 Minute Instant Pot Spaghetti is a cozy, family-friendly main dish. Pair it with a crisp green salad and some garlic bread for a classic combo. For a lighter contrast, serve with steamed green beans or a simple cucumber and tomato salad. Leftovers reheat well in the microwave or on the stovetop with a splash of water to loosen the sauce.

Variations and swaps

• Protein swaps: If you prefer, swap the ground beef for ground turkey or a plant-based ground meat substitute — use the same amount and follow the same steps.
• Cheesy twist: Stir in ½ to 1 cup shredded cheese after cooking for a creamy finish. Parmesan or a mild cheddar works nicely.
• Veggie boost: Add a cup of chopped mushrooms, bell pepper, or shredded zucchini during the sauté step with the beef to sneak in extra vegetables.

Make-ahead and storage

Store cooled leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave or on the stovetop over low heat, stirring occasionally and adding a tablespoon or two of water if the sauce seems too thick. For longer storage, freeze in freezer-safe containers for up to 3 months. Thaw overnight in the fridge before reheating.

Common questions

Can I use fresh tomatoes instead of marinara? Yes — if you have a chunky fresh tomato sauce or diced tomatoes, it will work. Keep the total liquid similar (two jars of marinara roughly equals 48 ounces of sauce) and use the 3 cups of water as listed to reach the proper liquid level for pressure cooking.

Do I need to break the spaghetti? Breaking the spaghetti in half helps it fit in smaller Instant Pots and prevents a tangled clump. If your pot is wide enough to accommodate full-length strands, they will cook just fine laid in a crisscross pattern.

What if the noodles stick together? Gently lift and separate them after cooking with tongs or a fork. Make sure the sauce was stirred down between the noodles before cooking to help prevent clumping. If you frequently have sticking issues, try stirring once gently after adding the water and sauce to make sure it’s distributed around the pasta.

Why keep the directions simple?

The beauty of this 10 Minute Instant Pot Spaghetti is its simplicity. Minimal steps mean less fuss and fewer chances for error. The Instant Pot does the heavy lifting, and the straightforward seasoning keeps the flavor balanced and familiar — exactly what you want on a weeknight.

Nutrition snapshot (approximate)

Per serving (assuming 6 servings): calories will vary based on marinara brand and beef fat content, but expect roughly 450–650 calories per portion. Using lean beef helps control saturated fat, and adding a side salad increases fiber and nutrients.
