Ingredients

Use the exact ingredient names and amounts below when you cook. The list ensures consistent results:

1 pound lean ground beef
1 teaspoon garlic powder
1/2 teaspoon salt
2 teaspoons Italian seasoning
1/4 teaspoon black pepper
1/4 teaspoon crushed red pepper flakes
2 tablespoons tomato paste
12 ounces uncooked thin spaghetti
2 1/2 cups water
1 (24-ounce) jar spaghetti sauce
1 (8-ounce) block cream cheese, cut into pieces and softened
1/3 cup freshly grated Parmesan cheese

Equipment

6-quart (or larger) electric pressure cooker/Instant Pot
Wooden spoon or heatproof spatula
Tongs or fork to break and move pasta
Measuring cups and spoons

Taste and texture tips

If you like a little more bite, use al dente timing for the pasta by reducing the manual pressure time by 1 minute. Prefer a smoother sauce? Let the pasta sit in the pot for a few minutes after stirring in the cream cheese to allow everything to meld. For extra brightness, finish each serving with a squeeze of lemon or a sprinkle of fresh herbs.

Step-by-step Instructions

Follow these clear steps in order for the best results. I’ve rewritten the directions to be straightforward and easy to follow while keeping the original ingredient amounts intact.

Prep the cream cheese: Cut the 8-ounce block of cream cheese into pieces and set them on the counter to soften while you cook so it melts easily when added at the end.
Brown the ground beef: Set your Instant Pot to the Sauté function and let it heat for about 1 minute. Add 1 pound lean ground beef to the pot. Use a wooden spoon to break the beef into small pieces as it cooks until no pink remains, about 5–7 minutes. Drain excess grease if the beef is particularly fatty, leaving just enough to coat the bottom.
Season the meat: Sprinkle 1 teaspoon garlic powder, 1/2 teaspoon salt, 2 teaspoons Italian seasoning, 1/4 teaspoon black pepper, and 1/4 teaspoon crushed red pepper flakes over the cooked beef. Stir to combine and let the spices toast for 30–60 seconds to bloom their flavor.
Add tomato paste: Stir in 2 tablespoons tomato paste and cook for about 1 minute, mixing thoroughly so the paste coats the beef and starts to caramelize slightly. This deepens the sauce’s flavor.
Deglaze with water: Pour in 2 1/2 cups water and use a spatula to scrape up any browned bits from the bottom of the pot. Scraping is crucial to prevent the Instant Pot from giving a burn warning once pressure is applied.
Add the spaghetti: Break 12 ounces uncooked thin spaghetti in half and scatter the pieces in an even layer over the beef and liquid. Do not stir. Arrange the pasta so it’s submerged as much as possible but still lies mostly in a single layer to ensure even cooking.
Pour in the sauce: Slowly pour 1 (24-ounce) jar spaghetti sauce evenly over the top of the pasta. Again, do not stir. The liquid should sit above the pasta, allowing the pressure to cook it through without pasta sticking to the bottom.
Set pressure cook time: Close and lock the Instant Pot lid and set the valve to the sealing position. Cancel Sauté and select Manual or Pressure Cook on high pressure for 8 minutes. The pot will take several minutes to come to pressure first.
Release pressure: When the cooking cycle finishes, perform a quick release by carefully turning the valve to venting. Once the float valve drops, open the lid away from your face to avoid steam.
Stir in cream cheese: Immediately add the softened pieces of 1 (8-ounce) block cream cheese to the hot pasta and sauce. Stir vigorously until the cream cheese melts and creates a smooth, creamy sauce. The heat from the pasta will melt it quickly. If some chunks remain, allow the mixture to sit on Sauté for 1–2 minutes while stirring to fully incorporate the cream cheese, then cancel Sauté.
Finish with Parmesan: Stir in 1/3 cup freshly grated Parmesan cheese until fully combined. Taste and adjust seasoning with additional salt and black pepper if needed.
Serve: Divide the Instant Pot Cream Cheese Spaghetti among bowls. If you like, garnish with extra Parmesan, a pinch of crushed red pepper, or a few torn basil leaves. Serve hot.

Make-ahead and storage

Refrigerate: Store leftovers in an airtight container for up to 3 days. Reheat gently on the stovetop over low heat with a splash of water to loosen the sauce, or microwave in 30-second increments, stirring between each interval.
Freeze: This dish freezes well. Portion into freezer-safe containers and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.

Substitutions and variations

Ground beef swap: Replace the 1 pound lean ground beef with ground turkey or ground chicken if you prefer white meat.
Vegetarian option: Omit the meat and use sautéed mushrooms, lentils, or a meat substitute in the same amount for a plant-forward version.
Spice level: Increase the crushed red pepper flakes to 1/2 teaspoon for more heat, or omit for a milder dish.
Creaminess boost: Stir in 1/4 cup heavy cream or a splash of pasta water if you want an even silkier finish.
Cheese variations: Swap the Parmesan for Pecorino Romano for a sharper bite, or add a handful of shredded mozzarella on top and broil briefly for a bubbly crust.

Common troubleshooting

Burn warning: If your Instant Pot shows a burn message, power it off, release pressure, and open the lid. Scrape any stuck bits from the bottom, add 2–3 tablespoons of water, and continue following the recipe from adding the pasta. Ensuring the pot is well deglazed after browning prevents this.
Too saucy or thin: Let the pot sit uncovered for 2–3 minutes after stirring in the cheeses to thicken, or switch to Sauté and simmer briefly while stirring.
Pasta too soft: For firmer pasta next time, reduce pressure cooking by 1 minute and use an immediate quick release.

Serving suggestions

This Instant Pot Cream Cheese Spaghetti is comforting on its own, but you can round it out with a simple green salad, garlic bread, or roasted vegetables. A crisp, peppery arugula salad dressed with lemon vinaigrette cuts through the richness beautifully.

Nutrition estimate (per serving)

Approximate nutrition per serving (recipe makes 4 servings): 600–700 calories, depending on your sauce choice and exact fat content in the beef. The dish provides a good balance of protein from the beef and dairy, plus carbohydrates from the spaghetti.

Final thoughts

Instant Pot Cream Cheese Spaghetti is a reliable weeknight winner: minimal hands-on time, easy cleanup, and a result that tastes like you spent hours coaxing flavor from the stove. The cream cheese adds a luxurious texture that pairs so well with tomato-based sauce and a hearty meat component. It’s a recipe to keep in your rotation when you want comfort without the fuss.
