This one-pot Instant Pot spaghetti turns hectic evenings into tasty family meals with zero hassle. Minimal effort, amazing taste - it's been a lifesaver at my house when we're short on time but big on hunger.
I found this gem after a crazy evening of driving kids around to sports. I needed to get food on the table fast. My kids thought I'd spent hours cooking when they tasted it. Now it's our go-to meal for those nights when we're rushed but still want something homemade.
Ingredients
- Extra virgin olive oil: forms the tasty foundation for cooking the meat
- Ground beef: adds filling protein though turkey or plant-based alternatives work great too
- Kosher salt: brings out all the tastes without being too salty
- Dried parsley: gives a light herby touch that works well with the sauce
- Onion powder: packs savory flavor without dealing with real onions
- Red pepper flakes: add a bit of kick that livens up the sauce
- Fresh garlic cloves: create that must-have smell and taste base
- Chopped kale or other greens: add healthy stuff without changing the comfort food vibe
- Water: creates the right cooking setup in your pressure cooker
- Jarred marinara sauce: cuts down prep time while giving rich tomato goodness
- Whole wheat spaghetti: brings nutty flavor and healthy fiber
- Parmesan cheese: adds creamy goodness and savory finish
- Fresh herbs: add a pop of color and fresh taste at the end
Step-by-Step Instructions
- Brown and Flavor:
- Set Instant Pot to sauté and pour in olive oil until it's hot. Toss in ground beef and break it into tiny bits with your spoon. This helps it cook evenly with no big chunks. While the meat browns, sprinkle on the salt, dried parsley, onion powder, and red pepper flakes. Keep breaking up the meat until it's fully cooked, around 5 minutes.
- Create Flavor Base:
- Throw in the minced garlic and cook for a quick 30 seconds until you can smell it but before it browns. Garlic gets bitter if it cooks too long, so keep an eye on it. Add 3/4 cup water and scrape the bottom of the pot to get all those tasty browned bits. This step stops the burn warning and grabs all the flavor from the pot.
- Add Veggies and Sauce:
- Now's when you add kale or whatever greens you're using. Pour in your marinara sauce and mix everything well. The greens will cook perfectly during pressure cooking without getting soggy. Make sure the sauce is spread out evenly for proper cooking.
- Layer the Pasta:
- Snap the spaghetti in half and place it in two crisscrossed layers on top of your meat mixture. Don't stir it in. This special way of adding pasta keeps it from sticking together and makes sure it cooks evenly. How you layer it really matters for getting the right texture.
- Add Extra Liquid:
- Take your empty sauce jar, add the remaining 1 1/4 cups water to it, put the lid on, shake it up, and pour this over your pasta. Still don't stir anything. This smart trick gets every last bit of sauce from the jar and adds just the right amount of water for perfect pasta.
- Cook Under Pressure:
- Close your Instant Pot lid and set the valve to sealing. Cook on HIGH pressure for exactly 8 minutes. This timing gives you pasta that's cooked but not mushy. While it cooks, all the flavors mix together as the pasta soaks up the yummy sauce.
- Release and Finish:
- As soon as it's done cooking, release the pressure right away. Open the lid carefully and stir in the Parmesan cheese. Don't worry if it looks a bit watery at first – the pasta will soak up more liquid as it sits. That's normal and makes the sauce just right.
- Let it Settle:
- Turn off the Instant Pot and let everything sit uncovered for a few minutes. This waiting time lets the sauce get thicker and the flavors come together. Give it one last stir before serving with extra Parmesan and fresh herbs on top for the perfect finish.

Make It Your Own
Feel free to play around with this dish. Want it hotter? Throw in extra red pepper flakes or a dash of hot sauce. Need more veggies? Toss in some chopped bell peppers, zucchini, or mushrooms with the garlic. Looking for a richer taste? Mix in a bit of heavy cream with the Parmesan. The basic recipe stays the same while you tweak it to what your family likes best.
Smart Storage
This Instant Pot spaghetti actually tastes better the next day as the flavors mix more. Keep it in sealed containers in your fridge for up to 4 days. The pasta might soak up more sauce while stored, so when you heat it up, add a splash of water or broth to thin the sauce. For easy lunches, divide into single portions that heat up quickly in the microwave.
Troubleshooting Tips
If your pot shows a burn warning while cooking, quickly release pressure, open it up, and add another 1/4 cup water. Gently mix just the top layer, close it back up, and finish cooking. This usually happens if there wasn't enough liquid or if food stuck to the bottom. Want soupier sauce? Use 1/4 cup less pasta. Need thicker sauce? Let it sit longer after cooking or try a thicker pasta like bucatini.

Frequently Asked Questions
- → Can I use turkey instead of ground beef?
Absolutely! Ground turkey works great here. Add a bit more olive oil when browning since turkey is leaner. The cook time and process stay the same, and you'll enjoy a lighter version of the dish.
- → Why shouldn't I mix the pasta before cooking?
It's best to leave the pasta untouched to avoid sticky clumps or triggering a burn warning. Keeping the layers intact ensures even cooking and helps build proper pressure in the pot.
- → What if I don't have whole wheat pasta?
Regular spaghetti works just fine. Stick to the same cook time (8 minutes) for normal pasta. For thinner options like angel hair, reduce cooking time to 5-6 minutes so it doesn't overcook.
- → Can I scale up this meal in the Instant Pot?
Yes, you can double it if it fits under the maximum fill line (about 2/3 full). Cooking time won't change, but the pot may take longer to build pressure. Make sure all noodles are covered in liquid for proper cooking.
- → Why is my pasta so watery after cooking?
A little extra liquid is normal and helps the pasta stay moist while the sauce thickens as it cools. Let the dish sit uncovered for a few minutes before serving to reach the right consistency.
- → How do I make this vegetarian?
Swap out the beef for plant-based crumbles, or sauté veggies like mushrooms, bell peppers, and zucchini as an alternative. Everything else stays the same, and you'll still get a tasty, filling dish.
