The Best 10-Minute Instant Pot Mac and Cheese (Creamy & Easy!)
There is nothing more comforting than a bowl of creamy mac and cheese. While the boxed version is a childhood staple, making it from scratch in the Instant Pot is actually just as fast—and you get to control every single ingredient that goes into the bowl.
This instant pot mac and cheese is my go-to for busy weeknights when I need a “Good Stuff” meal that the whole family will actually eat.
The Good Stuff Ingredient Swaps
Before we get to the cheese, let’s talk about the base. While most traditional macaroni is made with highly processed white flour, I love to use a high-quality organic option.
- The Pasta: I’m a huge fan of the Organic Cavatappi from the Costco 3-pack. It’s a sturdy short pasta that holds its shape beautifully in the pressure cooker.
- The Cheese: Simple Swap: Pre-shredded cheese in bags often contains potato starch or cellulose to keep it from sticking. For the creamiest, “clump-free” sauce, I recommend shredding your own organic cheddar or gouda from the block!
- The “Secret” Ingredients: We add a splash of hot sauce and dry mustard. Don’t worry, it’s not spicy! These just help cut through the richness of the cream and make the cheese flavor really pop.
Step-by-Step Instructions
Step 1: The Quick Cook
Place your pasta, water, salt, and butter into the Instant Pot.
Set your pot to High Pressure for 4 minutes.
🧁 Good Stuff Tip: If you use a different pasta, look at the box’s recommended cook time and divide it by two. If it’s an odd number like 9 minutes, just round down to 4. The Instant Pot is powerful, so rounding down prevents mushy noodles!
Step 2: Quick Release
Once the timer beeps, perform a Quick Release immediately. Wait for the pin to drop before opening the lid.
Step 3: The Creamy Finish
Stir in your heavy cream (or milk), hot sauce, and dry mustard. Now, add your shredded cheese one handful at a time, stirring constantly. Adding it slowly is the “Good Stuff” secret to avoiding those pesky cheese clumps!
Step 4: Serve & Enjoy
If it looks too thick, splash in a little extra milk until it’s exactly how you like it. You can keep the pot on the “Warm” setting while you serve.
Frequently Asked Questions
Why is my Mac and Cheese grainy?
This usually happens if the heat is too high or the cheese is added too fast. Be sure to turn off the “Sauté” function and add your shredded cheese one handful at a time, stirring until smooth before adding more. Also, using block cheese you shred yourself melts much smoother than the pre-bagged kind!
Can I use different types of pasta?
Yes! While I love the Costco Organic Cavatappi, you can use elbows, shells, or penne. Just remember the “Half-Time” rule: look at the box’s recommended stovetop time, divide by two, and round down to the nearest whole minute for your Instant Pot setting.
Is the hot sauce going to make it spicy?
Not at all! A teaspoon of hot sauce doesn’t add heat; it acts as a “flavor balancer.” It helps cut through the heaviness of the dairy and makes the cheddar taste sharper and more “real.
How do I store and reheat leftovers?
Store leftovers in an airtight container for up to 4 days. When reheating, add a tiny splash of milk before microwaving or heating on the stovetop. This brings back that “Good Stuff” creaminess that the pasta absorbs while sitting in the fridge.
