Detailed Directions and Instructions
Meat
Activate the sauté function on the Instant Pot. Add the olive oil, followed by the ground beef. Sprinkle in the garlic powder, onion powder, Italian seasoning, and kosher salt. If using, add the minced garlic as well. Sauté the mixture until the meat is browned and cooked through, ensuring that it is crumbled well.
Sauce
After the meat is cooked, add the pasta sauce, water, and Better Than Bouillon to the pot. Carefully break the spaghetti in half and add it to the mixture. Ensure that all the noodles are submerged beneath the liquid to cook evenly.
Cook
Once everything is combined, secure the lid on the Instant Pot and seal the vent. Set the pressure cooking setting to high and cook for 8 minutes.
Release Steam
After the cooking time is complete, place a towel over the vent to absorb any splatters. Perform a quick release of the steam to prevent overcooking the noodles.
Rest
Once the lid is opened, the mixture may look somewhat saucy. Use tongs to gently stir and distribute the sauce throughout the noodles. Allow the dish to rest for 10 minutes to enable the spaghetti to absorb some of the sauce and achieve the desired consistency.
Finish
Stir in the butter until it is completely melted and incorporated into the dish. Serve the spaghetti topped with grated Parmesan cheese, and garnish with fresh parsley or basil. Optionally, sprinkle with red pepper flakes for added heat.
Notes
Serving Size
This recipe serves approximately 4 to 6 people, depending on portion sizes.
Leftovers
Leftover spaghetti can be stored in an airtight container in the refrigerator for up to 3 days. Reheat on the stove or in the microwave, adding a splash of water if needed to loosen the sauce.
Substitutions
Feel free to substitute the ground beef with ground turkey or chicken for a lighter option. For a vegetarian version, you can use a meat substitute or add more vegetables like spinach or bell peppers.
Spice Level
Adjust the amount of red pepper flakes based on your preference for heat. For a milder flavor, omit the red pepper flakes or serve them on the side.
Fresh Herbs
If you have fresh herbs like basil or parsley, using them as a topping enhances the flavor and presentation of the dish.

Cook techniques
Sautéing Ground Beef
Sautéing involves cooking food quickly in a small amount of oil over medium-high heat. This technique helps to brown the ground beef, enhancing its flavor and texture.
Pressure Cooking
Pressure cooking uses steam and high pressure to cook food more quickly than traditional methods. In this recipe, the Instant Pot cooks spaghetti in just 8 minutes, infusing flavors and ensuring even cooking.
Quick Release
Quick release is a method where you carefully vent the steam from the Instant Pot immediately after cooking. This prevents overcooking the noodles and allows you to retain the desired texture.
Resting
Letting the dish rest after cooking allows the pasta to absorb the sauce better, achieving the right consistency and flavor.
Finishing Touches
Incorporating butter at the end adds richness and creaminess to the dish. Topping with Parmesan cheese and herbs enhances the overall presentation and flavor.
