Instant Pot Cream Cheese Spaghetti

Comforting, creamy, and effortlessly weeknight-friendly, this Instant Pot Cream Cheese Spaghetti is one of those recipes that feels indulgent while really being simple to pull together. With a rich tomato base, tender strands of spaghetti, and a velvety hit of cream cheese and Parmesan, it’s the kind of one-pot dinner that disappears fast. The flavors are familiar—tomato, Italian herbs, a hint of heat—and the texture is luxuriously smooth without being heavy. Below you’ll find the ingredient list, step-by-step instructions rewritten for clarity, and tips to make the dish your own.

Why this recipe works

Using the Instant Pot keeps cleanup minimal and speeds up cooking. Browning the ground beef first builds flavor, and pressure-cooking the pasta in the sauce lets the noodles absorb tomato flavor while finishing quickly. Stirring in cream cheese and Parmesan at the end creates a silky sauce that clings to every strand. This method gives you a reliably creamy finish without standing at the stove stirring for ages.

Ingredients

• 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- or 8-quart Instant Pot (or similar electric pressure cooker)
• Wooden spoon or silicone spatula
• Tongs or fork for breaking spaghetti if desired

Before you begin

• Take the cream cheese out of the fridge early so it softens to room temperature; that helps it stir in smoothly.
• Have the spaghetti ready. If your pot is smaller or you prefer, break the spaghetti in half to fit it more easily under the sauce.

Step-by-step Instructions

1. Set the Instant Pot to the Sauté function and allow it to heat for a minute.
2. Add the 1 pound lean ground beef to the pot. Cook, stirring and breaking the meat into small pieces, until it is mostly browned, about 4–6 minutes. If there is excess fat, carefully drain a little, leaving enough to coat the pot for flavor.
3. Sprinkle in 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. Stir to combine, letting the spices toast for about 30 seconds to bloom their flavors into the beef.
4. Stir in 2 tablespoons tomato paste and cook for 30–60 seconds, mixing it well with the meat so it darkens slightly and develops a richer flavor.
5. Pour in 2 1/2 cups water and use a spoon to scrape up any browned bits from the bottom of the pot. This prevents a burn notice and captures that savory flavor.
6. Add the 12 ounces uncooked thin spaghetti to the pot. Arrange the noodles in a crisscross or fan pattern so they’re mostly submerged and not packed straight down in a single bundle. This helps even cooking.
7. Pour the entire 24-ounce jar of spaghetti sauce over the top, covering the spaghetti as best as you can.
8. Secure the Instant Pot lid and set the valve to the Sealing position. Cook on Manual/Pressure Cook at high pressure for 8 minutes. (Thin spaghetti cooks quickly, and this time yields tender but not mushy noodles.)
9. When the cook time ends, allow a natural pressure release for 5 minutes, then carefully move the valve to Venting to release any remaining pressure. Open the lid once the float valve drops.
10. Give the spaghetti a gentle stir to distribute the sauce and loosen any clumped noodles. The sauce will be hot—use a long-handled spoon or spatula.
11. Add the 1 (8-ounce) block cream cheese (cut into pieces and softened) to the pot. Stir until the cream cheese is fully melted and incorporated into the sauce, creating a creamy, cohesive texture.
12. Stir in 1/3 cup freshly grated Parmesan cheese until melted and evenly combined. Taste and adjust seasoning if needed, adding a pinch more salt or pepper to suit your preference.
13. Serve hot, scooping a generous portion onto plates and finishing with extra Parmesan or a sprinkle of crushed red pepper flakes if desired.

Troubleshooting and tips

• If the Instant Pot shows a burn warning before pressure cooking, cancel, remove a small amount of liquid (carefully), stir to deglaze the bottom, and then try again. Ensuring the browned bits are scraped up before sealing prevents this.
• For a lighter version, swap the ground beef for ground turkey or a plant-based ground “meat” of equal weight—keep all other quantities the same.
• Want more vegetables? Stir in a cup of baby spinach or a cup of frozen peas after pressure cooking and let them wilt in the residual heat when you add the cheeses.
• For a cheesier finish, stir in an extra 1/4 cup Parmesan or a handful of shredded mozzarella when you add the cream cheese.
• Make it ahead: refrigerate leftovers in an airtight container up to 3 days. Reheat gently on the stovetop with a splash of water to loosen the sauce.

Serving suggestions

Pair this Instant Pot Cream Cheese Spaghetti with a crisp green salad and crusty bread for a complete meal. A simple side of sautéed green beans or roasted broccoli adds color and crunch. For a brighter contrast, finish plates with a squeeze of lemon on the salad or a few torn basil leaves over the pasta.

Notes on ingredients

All ingredient amounts are listed above and should be followed as written for reliable results. The dish relies on the cream cheese and Parmesan for its signature creaminess; use full-fat cream cheese for the silkiest texture. If your spaghetti sauce is very thick, it will still work because you’re adding water; conversely, if it’s thin, the final sauce will be slightly looser but still creamy after the cheeses are stirred in.

Why the timing matters

The 8-minute pressure cook time is chosen for thin spaghetti to achieve tender, intact noodles without becoming mushy. The brief natural release allows the pasta to finish cooking gently while avoiding a sudden violent boil when you open the lid. Adding the cheeses after pressure cooking prevents separation and gives you a smooth, well-emulsified sauce.

Make it your own

This Instant Pot Cream Cheese Spaghetti is a great base for personalization. Swap in different dried herbs, add sautéed mushrooms with the meat, or finish with a few red pepper flakes for more heat. If you prefer a smokier flavor, a tablespoon of smoked paprika mixed with the spices creates a nice depth. However you adapt it, keep the ingredient amounts the same to maintain the balance of liquid and pasta for the pressure-cooking step.
