Ingredients

For The Pasta:

  • 1 pound elbow macaroni or other small pasta
  • 4 cups water
  • 1 tsp salt
  • 1 cup milk
  • 2 tbsp unsalted butter

For The Sauce:

  • 2 cups shredded cheddar cheese
  • 1 cup shredded mozzarella cheese
  • 1 tbsp harissa paste adjust to taste
  • ½ tsp smoked paprika
  • Salt & black pepper to taste

Instructions

  • Add the elbow macaroni, water, and salt to the Instant Pot. Secure the lid, set the valve to sealing, and cook on High Pressure for 4 minutes. Once the cooking time is complete, perform a quick release.
  • Switch the Instant Pot to Saute mode. Stir in the milk and butter until the butter is fully melted and the mixture is smooth and creamy.
  • Gradually add the shredded cheddar and mozzarella cheese, stirring continuously until the cheese is fully melted and the sauce becomes rich and velvety.
  • Stir in the harissa paste and smoked paprika. Season with salt and black pepper to taste, adjusting the spice level if needed.
  • Turn off Sauté mode and let the mac and cheese sit for 2–3 minutes to thicken slightly.
  • Serve warm, garnished with a sprinkle of smoked paprika or fresh herbs if desired.

Notes

Use quick release only to prevent overcooked pasta
Add cheese gradually for a smooth, creamy sauce
