What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, so you can throw this together even on a busy day.

• Spaghetti: 8 ounces (225 grams) of dried spaghetti, broken in half for easier cooking in the Instant Pot.
• Ground Beef or Turkey: 1 pound (450 grams), lean for less grease (optional for a vegetarian twist, see variations).
• Olive Oil: 2 tablespoons (for sautéing and flavor).
• Onion: 1 medium, finely chopped (adds sweetness and depth).
• Garlic: 3 cloves, minced (because garlic is life).
• Canned Crushed Tomatoes: 1 can (28 ounces / 800 grams), or use fresh tomatoes in summer for a brighter taste.
• Tomato Paste: 2 tablespoons (for richness and body).
• Beef or Vegetable Broth: 2 cups (480 ml), helps cook the pasta and infuse flavor.
• Italian Seasoning: 2 teaspoons (blend of oregano, basil, thyme).
• Salt and Pepper: To taste (essential for balancing flavors).
• Red Pepper Flakes: Optional, a pinch for a little heat.
• Fresh Basil or Parsley: For garnish (adds freshness and color).
• Parmesan Cheese: For serving (totally optional but highly recommended!).

For best results, I recommend using a high-quality canned crushed tomato brand like San Marzano if you can find it. Also, breaking spaghetti in half helps it fit better and cook evenly in the Instant Pot without sticking. If you want a vegetarian or vegan version, just swap the ground meat for mushrooms or plant-based crumbles and use vegetable broth instead.

Equipment Needed

• Instant Pot or Electric Pressure Cooker: The star of this recipe. If you don’t have one, a stovetop pressure cooker works too, but cooking times may vary.
• Wooden Spoon or Silicone Spatula: For sautéing and stirring without scratching the pot.
• Measuring Cups and Spoons: To keep your ingredient amounts precise.
• Knife and Cutting Board: For chopping onions, garlic, and herbs.
• Colander: Optional, if you want to rinse your pasta before cooking (though it’s not necessary here).

I’ve tried this recipe with different Instant Pot models, and honestly, they all do a fantastic job. Just make sure your sealing ring is in good shape to avoid any pressure leaks. If you’re on a budget, older models or even basic versions will still get you dinner on the table fast with no fuss. And trust me, the cleanup is way easier than your typical pot and pan pile-up.

Preparation Method

1. Sauté the Aromatics and Meat (About 7 minutes): Set your Instant Pot to Sauté mode. Add 2 tablespoons olive oil, then toss in chopped onion and garlic. Cook until softened and fragrant, about 3-4 minutes. Add ground beef or turkey and brown it thoroughly, breaking it apart with your spoon. Drain excess fat if there’s too much (you want flavor, not grease!).
2. Add Tomato Elements (2 minutes): Stir in the 2 tablespoons of tomato paste and cook for 1 minute to deepen flavor. Pour in the canned crushed tomatoes, beef broth, Italian seasoning, salt, pepper, and optional red pepper flakes. Mix well to combine everything.
3. Layer the Pasta (No stirring needed!): Break the spaghetti in half and layer it in a crisscross pattern on top of the sauce mixture. Do not stir—just gently press it down so it’s mostly submerged but not stirred around. This layering helps prevent sticking.
4. Pressure Cook (8 minutes): Close the lid and set the valve to sealing. Cook on Manual or Pressure Cook mode for 8 minutes at high pressure. (For thinner pasta, 7 minutes might work better—adjust based on your Instant Pot’s quirks.)
5. Natural Release (5 minutes): When the timer beeps, let the pressure release naturally for 5 minutes, then carefully do a quick release to vent any remaining pressure.
6. Final Stir and Serve: Open the lid, give everything a gentle stir to combine the pasta and sauce. It should be thick, glossy, and irresistibly saucy. Taste and adjust seasoning if needed. Garnish with fresh basil or parsley and a sprinkle of parmesan cheese.

Some quick tips: If you find the sauce too watery after cooking, hit Sauté mode again for a minute or two to thicken it up. And don’t worry if the pasta isn’t perfectly al dente on the first try—Instant Pot models vary slightly, so a little tweaking is normal.

Cooking Tips & Techniques

Instant Pot spaghetti is honestly a life-saver, but there are a few tricks I learned the hard way. First, layering the pasta on top of the sauce without stirring is key. Stirring before pressure cooking often leads to clumps and sticking. Also, breaking the spaghetti in half helps it fit better and cook evenly—whole strands can clump or cook unevenly.

Don’t skip the natural pressure release for at least 5 minutes. It allows the pasta to finish cooking gently and soak up more sauce without turning mushy. If you rush straight to quick release, the pasta might be undercooked or the sauce too thin.

When browning the meat, I like to drain excess fat if there’s a lot—too much oil can make the sauce greasy. However, leaving a bit adds flavor. Using lean ground beef or turkey keeps it balanced.

Finally, multitasking during the pressure cook time is a huge win. Use those 8 minutes to set the table, chop salad veggies, or pour yourself a glass of wine—because dinner’s almost ready with zero stress.

Variations & Adaptations

• Vegetarian Version: Skip the meat and add sliced mushrooms or diced zucchini for texture. Use vegetable broth instead of beef broth.
• Spicy Kick: Add extra red pepper flakes or a splash of hot sauce before pressure cooking for a fiery twist.
• Gluten-Free Option: Swap regular spaghetti with gluten-free pasta. Note that cooking times may vary slightly, so check pasta texture and adjust as needed.
• Cheesy Boost: Stir in ½ cup (120 ml) of ricotta or shredded mozzarella right after cooking for a creamy, indulgent finish.
• Fresh Herb Upgrade: Toss in chopped fresh basil and parsley after cooking instead of just as garnish for a garden-fresh aroma.

I once tried adding roasted red peppers and olives to the sauce—gave it a Mediterranean vibe that my family loved. Feel free to experiment; this recipe is forgiving and adaptable.

Serving & Storage Suggestions

Serve your easy Instant Pot spaghetti hot, straight from the pot, with a generous sprinkle of parmesan and fresh herbs. Pair it with a crisp green salad or garlic bread for a comforting meal that feels complete. A glass of red wine or sparkling water with lemon brightens the palate beautifully.

Leftovers store well in an airtight container in the fridge for up to 3 days. When reheating, add a splash of water or broth to loosen the sauce and heat gently on the stove or in the microwave to keep the pasta from drying out. You can also freeze portions for up to 2 months—just thaw overnight in the fridge before reheating.

Flavors actually deepen after sitting, so sometimes I make this a day ahead for a next-day dinner that tastes even better. Just reheat slowly and enjoy.
