Instant Pot Spaghetti: Dinner in 15 Minutes!
Ingredients
- 1 tablespoon olive oil
- 1 pound ground beef (I use 85/15)
- 1/2 teaspoon each garlic powder, onion powder, and Italian seasoning
- 1 clove garlic, minced (optional)
- 1 teaspoon kosher salt
- 1 (24 ounce) jar pasta sauce
- 1 3/4 cups water
- 1 teaspoon Better Than Bouillon (I use the chicken base)
- 8 ounces spaghetti, broken in half
- 4 tablespoons butter
Instructions
- Turn the sauté function on in the Instant Pot. Add olive oil, ground beef, garlic powder, onion powder, Italian seasoning, minced garlic (if using), and kosher salt. Sauté until the meat is browned and cooked through.
- Add the jar of pasta sauce, water, chicken bouillon, and broken spaghetti. Ensure the spaghetti is mostly submerged under the liquid.
- Secure the lid, set the valve to sealing, and cook on high pressure for 8 minutes.
- Once cooking is complete, carefully perform a quick release of the pressure. Lay a towel over the vent to manage splatters. This prevents the noodles from overcooking.
Notes
– Ensure spaghetti is mostly submerged to cook evenly.
– Perform a quick release immediately to prevent overcooking. Allergens: Wheat. Nutrition information is an estimate, calculated automatically. Values vary with brands, substitutions and portion sizes.
The technique that makes it
The magic behind this instant pot spaghetti lies in the one-pot cooking method, specifically how the liquid and pasta interact under pressure. By adding the spaghetti directly to the pot with the sauce and liquid, the pasta cooks evenly and absorbs flavor from the sauce as it rehydrates. The key is the precise ratio of liquid to pasta and the correct pressure cooking time. The water and Better Than Bouillon create a flavorful broth, while the pasta absorbs this liquid as it cooks. Breaking the spaghetti in half is crucial for fitting it into the Instant Pot and ensuring it is fully submerged in the liquid, which is essential for proper, even cooking. The initial sauté of the ground beef and aromatics builds a foundational flavor before the pressure cooking begins, infusing the entire dish.
Troubleshooting
- Pasta is mushy: This usually happens if the pressure cooking time is too long. Reduce the cook time by 1-2 minutes in future attempts. Ensure you are using the correct amount of liquid; too much can also contribute to overcooked pasta.
- Pasta is undercooked or crunchy: The pressure cooking time may be too short, or there wasn’t enough liquid. Ensure the spaghetti is fully submerged. For future attempts, increase the cook time by 1-2 minutes.
- Sauce is too thin: Insufficiently reduced sauce can result in a watery consistency. After pressure cooking, you can remove the lid and use the ‘Sauté’ function to simmer and thicken the sauce for a few minutes.
- Burn notice: This can occur if there isn’t enough liquid, or if food has stuck to the bottom of the pot. Ensure the initial sauté is done carefully, deglazing the pot if necessary, and that the liquid-to-pasta ratio is accurate.
Substitutions
- Ground Beef: You can substitute ground turkey, chicken, or Italian sausage for the ground beef. The flavor profile will change slightly, but the cooking method remains the same. For a vegetarian option, use plant-based ground crumbles.
- Pasta Sauce: Any brand or flavor of marinara or pasta sauce will work. For a richer flavor, consider using a sauce with added vegetables or a premium blend.
- Water/Bouillon: You can use vegetable broth or chicken broth instead of water and Better Than Bouillon for a similar liquid base. Adjust seasoning as needed, as broths can vary in salt content.
- Spaghetti: While spaghetti is specified, other long pasta shapes like linguine or fettuccine can be used, but they may need to be broken to fit. Shorter pasta shapes like penne or rotini will also work, but may require a slight adjustment in cooking time.
Pro tips
- Use a good quality pasta sauce for the best flavor.
- Ensure spaghetti is mostly submerged to cook evenly.
- Perform a quick release immediately to prevent overcooking.
