Ingredients You’ll Need
The beauty of this Instant Pot Mac and Cheese Recipe lies in its simplicity and how these few ingredients come together to create magic. Every element plays a key role in building flavor, creaminess, and that inviting golden color you crave in classic mac and cheese.
- 4 cups water: The cooking base that softens the pasta evenly and prevents sticking under pressure.
- 1 lb elbow macaroni pasta: The perfect shape for holding cheesy sauce in every bite.
- 1 1/2 tsp fine sea salt: Enhances all the flavors without overpowering the dish.
- 1 tsp ground mustard: Adds a subtle tang that brightens the cheese flavor beautifully.
- 1/2 tsp paprika: Delivers a gentle smoky warmth and vibrant color to the pasta.
- 1/2 tsp garlic powder: Provides a savory depth that rounds out the seasoning.
- 2 Tbsp unsalted butter: Creates richness and smooth texture when melted into the pasta.
- 12 oz can evaporated milk: Gives the sauce creamy body without being heavy or greasy.
- 2 cups shredded mild cheddar cheese: The star cheese that offers sharpness and melty goodness.
- 1 cup shredded Monterey Jack cheese (or Mozzarella): Adds stretchiness and mild creaminess for perfect balance.
- Freshly cracked black pepper (optional for garnish): Finishing touch that brightens each spoonful with just a hint of spice.
How to Make Instant Pot Mac and Cheese Recipe
Step 1: Combine Ingredients in the Instant Pot
Start by adding 4 cups of water, the elbow macaroni, salt, ground mustard, paprika, and garlic powder into your 6-quart Instant Pot. Give everything a good stir to distribute the seasonings evenly. This foundation will infuse flavor into the pasta as it cooks, so don’t skip the mix!
Step 2: Add Butter and Pressure Cook
Next, toss in the butter on top of the pasta mixture. Place the lid securely on the Instant Pot and set it to manual high pressure for exactly 4 minutes. The butter will melt inside and lend a lovely richness while the pasta cooks to tender perfection in record time.
Step 3: Quick Release and Turn Off
After the cooking cycle finishes, carefully perform a quick release according to your Instant Pot’s instructions, making sure all pressure is released safely. Once the steam is gone, turn off the pot. This step is crucial to ensure your pasta stops cooking and maintains the ideal texture for creamy mac and cheese.
Step 4: Stir in Evaporated Milk
Immediately pour in the 12 ounces of evaporated milk and stir well. The warm pasta will absorb the milk, setting the stage for a smooth, velvety sauce that isn’t too heavy or overly thick.
Step 5: Melt in the Cheese
Add the shredded cheeses a cup at a time, stirring thoroughly after each addition. This gradual approach helps avoid clumps and allows the cheese to melt uniformly, creating that luscious, gooey sauce everyone loves. Taste and adjust with pepper or a dash of salt if needed. If you find the sauce a bit too thick, stir in small amounts of hot water until it reaches your desired consistency.
How to Serve Instant Pot Mac and Cheese Recipe

Garnishes

Side Dishes
This mac and cheese pairs wonderfully with crisp green salads, roasted vegetables, or even a tangy coleslaw. If you’re going all out, crispy baked chicken or barbecued ribs make for a hearty, crowd-pleasing meal alongside it.

Make Ahead and Storage
Storing Leftovers
Store any leftover Instant Pot Mac and Cheese Recipe in an airtight container in the refrigerator for up to 3 days. It maintains its creamy texture well if kept chilled promptly and covered tightly.
Freezing
You can freeze this mac and cheese, but keep in mind that the texture of the cheese sauce may change slightly upon thawing. Place portions into freezer-safe containers or bags and freeze for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating
Reheat gently in a microwave or on the stovetop over low heat, stirring often to prevent sticking. Add a splash of milk or water to revive the sauce’s creaminess if it seems thick or dry after reheating.
FAQs
Can I use other types of pasta for this recipe?
Absolutely! While elbow macaroni is classic, you can use any short pasta like shells, rotini, or penne that cooks quickly under pressure. Just watch the cooking time for different pasta shapes if you adjust amounts.
What kind of cheese works best?
The recipe calls for mild cheddar and Monterey Jack because they melt beautifully and give a great balance of flavor and texture. Feel free to experiment with sharp cheddar, Gruyere, or fontina for different tastes.
Can I make this recipe dairy-free?
You can substitute evaporated milk with a creamy non-dairy milk like cashew or oat milk, and swap cheeses for vegan alternatives, but the results might be less creamy and rich. The Instant Pot Mac and Cheese Recipe is beloved for its traditional dairy richness.
Is the cooking time always 4 minutes?
Yes, the pasta cooks perfectly in 4 minutes under high pressure in the Instant Pot. Overcooking can make it mushy, so stick to the recommended time for best texture.
Can I add protein to this mac and cheese?
Definitely! Stir in cooked bacon, shredded chicken, or even cooked sausage after the cheese has melted for a more substantial meal. Just make sure any added ingredients are pre-cooked since the cooking time only covers the pasta.
