Instant Pot Spaghetti Recipe

If you love easy weeknight dinners that taste like they took hours, this Instant Pot Spaghetti Recipe is for you. It delivers rich, tomato-y sauce, browned beef, and perfectly tender spaghetti in a single pot with minimal fuss. The ingredients are simple and pantry-friendly, and the method is straightforward: brown, deglaze, layer, pressure cook, and finish with a shower of grated Parmesan. Follow the clear, step-by-step directions below and you’ll have a comforting bowl of pasta in under 30 minutes of active time.

Why this Instant Pot Spaghetti Recipe works

This recipe takes advantage of the Instant Pot’s ability to meld flavors quickly. Browning the ground beef builds savory depth, while a short pressure-cook time softens the broken spaghetti exactly right without overcooking. Crushed tomatoes and a touch of dried oregano form a classic base, and Stone House Seasoning adds a balanced blend of herbs and spices for immediate flavor. Breaking the spaghetti into halves helps it nestle into the sauce for even cooking. Finish with grated Parmesan for a salty, nutty lift.

Ingredient Notes

• 2 pounds ground beef — Use any 80/20 or leaner ground beef you prefer. It browns nicely and gives the sauce its meaty backbone.
• 1 teaspoon Stone House Seasoning — A pre-mixed blend of herbs and spices. If you don’t have this brand, use an equal amount of your favorite all-purpose seasoning.
• 1 teaspoon dried oregano — Adds classic Italian-herb aroma and flavor.
• 1 (28-ounce) can crushed tomatoes — Use a good-quality canned crushed tomato for the best sauce texture and flavor.
• 4.5 cups water — The liquid needed for the Instant Pot to come to pressure and for the pasta to cook evenly.
• 1 pound spaghetti noodles, broken into half — Breaking the spaghetti helps it fit into the pot and cook through without clumping.
• 1/2 cup Parmesan cheese, grated — Stirred in at the end for creamy depth and savory brightness.

Equipment

• Instant Pot or other electric pressure cooker (6-quart recommended)
• Wooden spoon or heatproof spatula
• Measuring cups and spoons
• Tongs for stirring and serving

Prep Ahead

You can measure spices and grate the Parmesan ahead of time to save a few minutes. Break the spaghetti into halves just before cooking to keep them from sticking together.

Step-by-step Directions

The following directions have been rewritten for clarity while keeping the order and ingredient amounts from the original list. Read through once, then follow each numbered step.

1. Set your Instant Pot to the Sauté function and allow the inner pot to warm for a minute. Add the 2 pounds ground beef to the hot pot. Use a wooden spoon or spatula to break the meat into small pieces as it cooks. Continue cooking until the beef is fully browned and no longer pink, about 6–8 minutes.
2. Once the beef is browned, sprinkle 1 teaspoon Stone House Seasoning and 1 teaspoon dried oregano over the meat. Stir well so the seasonings coat the browned beef evenly. Cook for about 30 seconds to wake up the herbs and toast the seasoning slightly, which deepens the flavor.
3. Pour in the 1 (28-ounce) can crushed tomatoes directly over the seasoned beef. Use your spoon to scrape up any browned bits from the bottom of the pot—this deglazing step prevents a burn notice and adds flavor to the sauce. Stir until the meat and tomatoes are well combined.
4. Add 4.5 cups water to the pot. Stir the mixture so the water distributes evenly through the sauce. The total liquid should cover the meat and create a sauce base for the pasta to cook in.
5. Take the 1 pound spaghetti noodles and break them into halves. Scatter the broken spaghetti over the tomato-beef mixture. Do not stir the pasta into the sauce aggressively; instead, gently press the pasta down so it is submerged and mostly even. The pasta will hydrate and soften into the liquid as it cooks.
6. Secure the Instant Pot lid and make sure the pressure release valve is set to the Sealing position. Select the Manual or Pressure Cook function and set the cook time for 8 minutes on high pressure. The pot will take several minutes to come to pressure before the cook time begins.
7. When the 8-minute pressure-cooking time finishes, allow the pressure to release naturally for 5 minutes. After that initial natural release, carefully turn the pressure release valve to Venting to release any remaining steam. When the float valve drops and it’s safe to open, remove the lid away from your face.
8. Open the lid and use a long-handled spoon or tongs to stir the pasta and sauce thoroughly. The sauce will be hot and slightly thinned from the cooking liquid; stirring helps the spaghetti separate and finish absorbing the sauce. If the pasta seems very wet, let it sit for a minute to thicken; if it seems too firm, you can return the lid and let it rest for another 1–2 minutes off heat—the residual heat will finish the noodles.
9. Once the spaghetti reaches your preferred doneness, stir in 1/2 cup Parmesan cheese, grated, until it melts into the sauce and becomes creamy. Taste and adjust seasoning if needed—add a pinch more Stone House Seasoning or a sprinkle of salt and pepper to taste.
10. Serve hot, scooped into bowls and topped with extra Parmesan if desired. Leftovers keep well in an airtight container in the refrigerator for 3–4 days; reheat gently on the stovetop with a splash of water to loosen the sauce, or microwave in short intervals stirring between.

Troubleshooting tips

• If your Instant Pot shows a burn warning when you start pressure cooking, cancel the cycle, open the pot, and stir to deglaze again—make sure no browned bits are stuck to the bottom. Adding the crushed tomatoes and water as directed usually prevents this.
• If the pasta is unevenly cooked, try to arrange the broken noodles more evenly next time and press them down so they are at least partially submerged.
• If the sauce is too thin after cooking, let the pot sit with the lid off for a few minutes to reduce, or switch to Sauté mode for 2–3 minutes and stir until thickened.

Variations and add-ins

• Vegetables: Stir in a cup of spinach, chopped bell peppers, or sliced mushrooms during the last few minutes after pressure cooking. They’ll wilt and blend into the sauce.
• Cheese: For a creamier texture, stir in a few tablespoons of cream cheese or a splash of heavy cream along with the Parmesan.
• Spice: Add crushed red pepper flakes with the dried oregano if you like heat.
• Herbs: Fresh basil or parsley stirred in just before serving brightens the final dish.

Serving suggestions

This Instant Pot Spaghetti Recipe pairs wonderfully with a crisp green salad and crusty bread to soak up the sauce. For a heartier meal, serve alongside roasted vegetables or a simple garlic sautéed greens dish.

Storage and reheating

Cool leftovers for no more than two hours before refrigerating in an airtight container. Reheat on the stovetop over low heat with a splash of water, or microwave in short bursts, stirring between intervals. If the sauce has thickened in the fridge, let it warm slowly so the pasta rehydrates evenly.
