Ingredients You’ll Need

For the base:

• 1 lb (450 g) elbow macaroni (uncooked): the classic choice for creamy mac & cheese that holds sauce beautifully.
• 4 cups water: enough liquid for perfect pressure cooking — no draining needed!
• 1 tsp salt: enhances flavor right from the start.
• 2 tbsp butter: adds richness and helps create a silky sauce.
• 1 cup whole milk (or evaporated milk for a creamier version): gives the sauce body and that luscious texture.
• 2 cups shredded cheddar cheese (mild or medium — not orange): melts smoothly and keeps the color naturally creamy.
• ¼ tsp garlic powder: a subtle flavor boost that makes the cheese pop.

Optional add-ins:

• Crumbled bacon or diced ham
• A dash of hot sauce or paprika for kick
• Broccoli florets or peas for extra color and texture
• A sprinkle of breadcrumbs if you want a crispy topping

Tools You’ll Need

• Instant Pot 6-Quart (affiliate link)
• Wooden spoon or silicone spatula
• Box grater (freshly shredded cheese = creamy sauce!)
• Measuring cups and spoons
• Airtight glass containers for storage

How to Make Instant Pot Macaroni & Cheese

Combine Everything in the Pot: Add macaroni, water, salt, and butter to the Instant Pot. Stir to combine so the pasta cooks evenly and nothing sticks to the bottom.

Pressure Cook: Close the lid and set the valve to Sealing. Cook on High Pressure for 4 minutes.

Quick Release: When the cooking cycle ends, quick release the pressure immediately. Open the lid carefully — you’ll notice a bit of extra liquid, which is perfect for the sauce base.

Stir & Thicken: Stir well. The pasta may look a little watery at first but will begin to thicken as you mix.

Add Dairy & Cheese: Pour in the milk and stir in the shredded cheddar cheese. Keep stirring until the sauce is smooth, creamy, and fully melted.

Rest & Serve: Let the mac and cheese sit for 2–3 minutes before serving. This short rest helps the sauce thicken to that perfect, silky texture.

Pro Tip: Use freshly shredded cheese for the creamiest results — pre-shredded varieties often have anti-caking agents that make sauces grainy.

Variations You’ll Love

• Bacon & Gruyère Mac: Smoky, rich, and fancy.
• Buffalo Mac: Stir in buffalo sauce and top with blue cheese.
• Truffle Mac: Add a drizzle of truffle oil before serving.
• Vegan Mac: Use gluten-free pasta, plant milk, and vegan cheddar — add nutritional yeast for flavor.

Storing & Reheating Leftovers

• Store leftovers up to 4 days in an airtight container.
• Reheat on the stove or microwave with a splash of milk to revive the creaminess.
• Freezer option: Portion into bags, flatten, and freeze for up to 1 month. Thaw overnight and reheat gently.
