Ultra-Creamy Instant Pot Mac & Cheese
Ingredients
- 1 lb elbow macaroni (uncooked)
- 4 cups water
- 1 teaspoon salt
- 3 tablespoons butter (cut into pieces)
- 2 1/2 cups shredded cheese (sharp cheddar/Italian blend)
- 1/2 cup whole milk
Step-by-Step Instructions
-
Pressure Cook
Add uncooked macaroni, water, and salt to the Instant Pot. Seal and cook on high pressure for 4 minutes.

-
Quick Release
Once finished, immediately release the pressure to prevent the pasta from overcooking.

-
Incorporate Butter
Stir in butter until fully melted and emulsified with the starchy pasta water.

-
The Cheese Matrix
Add cheese and milk gradually. Stir vigorously until the sauce is thick, smooth, and glossy.

-
Final Rest & Serve
Let it sit for 5 minutes to allow the sauce to tighten, then serve warm.

Pro-Tips
- Always shred your own cheese for the smoothest melt.
- Do not skip the 5-minute rest period; it is vital for texture.
- If the sauce is too thick, add milk one tablespoon at a time.
