We are a macaroni and cheese loving family. It IS the epitome of comfort food, after all. Not only do the kids love it, but Ryan and I are also big fans. We’ve tried many different brands of delicious mac n’ cheese. We’ve even tried making our own homemade mac & cheese a few times, but our kids were never very impressed with our attempts.

Not only that, it really is a pain to stand over the stove waiting for the water to boil. Is it just me or doesn’t it always seem to take a lifetime for that water to come to a boil? And just as the water begins to boil, I undoubtedly get distracted by an urgent text from someone needing “SOMETHING VERY IMPORTANT”, “RIGHT NOW”.

And what happens?
Water ends up boiling over the pot and all over the stove. Ugh!
Not to mention the foggy glasses and unwanted steam bath I get when straining the pasta precariously over the sink. I’m so done with pasta on the stove!

Delicious Homemade Mac & Cheese Just Got Easy
In comes the Instant Pot… and now, our mac and cheese game is strong!!
Ever since we made our first batch of macaroni and cheese in the Instant Pot we haven’t made it any other way!
Not having to strain the pasta, alone, is worth making it in the Instant Pot. Add to that the fact that I don’t have to worry about the water boiling over, AND I get to add my own choice of cheeses…
I’m sold!!

This Is The Absolute Best Macaroni and Cheese

This mixture of cheeses is, in our book, perfect! I’ve even made it a couple of times in the same week, and got zero complaints about the repeat meal!
Just a few simple steps and you’ll be enjoying some delicious and creamy mac n’ cheese. Here we go!

Making Perfect Mac and Cheese in the Instant Pot
Like I said, making macaroni and cheese in your Instant Pot is super duper easy! Once you try it, you’ll never go back to making it on the stove!
Gather Your Ingredients
This recipe requires a few ingredients, and most of them you probably have on hand. Of course, you need elbow macaroni, I like using the small elbows. You’ll also need water, salt, butter, one can of evaporated milk, ground mustard, and cheese!




Small Elbow Macaroni Is the Best Pasta for This Recipe
You can use all kinds of pasta, but in all my experimenting, I found that the small elbow macaroni came out the best. I tried bow tie, large elbows, and a couple of others. Everyone agreed that the small elbow macaroni had the best consistency in the end.

Add the Pasta to the Instant Pot
First, you will need to add 4 cups of water to the pot. Then add 1 pound of elbow macaroni.


Gently Mix in the Salt and Butter
Add the 2 tablespoons of salted butter and, finally, add the two teaspoons of salt. You can gently mix everything together.

Cook for Only Two Minutes in the Instant Pot
Close your Instant Pot and set it to sealing. Press the Manual button (in newer models it’s Pressure Cook), and set it for 2 minutes on High Pressure. Yes, you read that right, 2 minutes.

Prep the Four Cheeses
So here’s the deal, you can use your favorite cheese in this recipe, BUT I highly recommend that you try out my combination first. We tested several combinations of cheeses until we ended up with this one. The cheese melts really easily, there are no funny textures and there’s no extra strong cheese flavor your kids will frown upon.

You will need mild cheddar cheese, Swiss cheese, Havarti and Gouda. See the recipe below for the exact amounts of each.

In total, you will use 2 ½ cups of shredded cheese. I find it’s cheaper to buy the blocks of cheese and shred them myself. It can be done quickly, and you’ll have time to do it while your Instant Pot is coming to pressure and your pasta cooks.

Avoid a Mess with a Two Minute Natural Pressure Release
Now, this is a very important step. Since this is pasta we are cooking, and it is starchy, it stands to make a mess when you release the pressure.
So, once the pot has come to pressure and the 2 minutes of cooking time is up, you will allow for a 2-minute Natural Pressure Release (NPR). This will let the pasta continue cooking while allowing time for any foam to settle inside the pot. This prevents such a mess when you release the pressure.
After the 2-minute NPR, you will do a CONTROLLED release. Don’t open the valve all the way. Just open it about halfway. There will still be a little bit of splatter, but nothing you can’t clean up quickly as it’s releasing.

Alternatively, you can use my Flip-The-Trivet for Mess-Free Pasta Method. This method will allow you to release the pressure more quickly without making a mess.
Perfect Macaroni Pasta in the Instant Pot
Once the pin drops, open your pot. Perfect Pasta!
The best part?
No need for a strainer!

Add The Remaining Ingredients
Now, you can add the can of evaporated milk, and stir it into the macaroni. Yes, you can use regular milk, but I always add evaporated milk to mine. It makes the macaroni and cheese creamier.


Finally, you can add the ground mustard and the cheeses. Mix everything together well and continue mixing until the cheese has melted completely.

The ground mustard really brings out some great flavors in the macaroni and cheese. You can’t taste “mustard” but it really does do something for it. If you must leave it out, then everything will be OK, but I really recommend adding it if you can.
Serve Your Instant Pot Mac and Cheese and Enjoy
Now it’s time to enjoy!
We love, love, love adding bacon bits on top of each serving. That’s pretty much how my kids eat it every time.

In my kid’s and hubby’s opinions, this is the best macaroni and cheese around. This is a perfect recipe for when you have very little time to cook a meal. You can add different things to it to make it heartier as well. See the recipe below for some of my suggestions.
I hope you enjoy your mac n’ cheese!

Instant Pot Mac and Cheese
CREAMY MACARONI PASTA MADE WITH A SPECIAL BLEND OF FOUR CHEESES

Ingredients
- 4 cups water
- 1 pound elbow pasta
- 2 tablespoons butter (salted)
- 2 teaspoons kosher salt
- 1 teaspoon ground mustard
- 1 can evaporated milk 12 fluid ounce can
- 1 cup mild cheddar cheese shredded
- ½ cup swiss cheese shredded
- ½ cup gouda cheese shredded
- ½ cup havarti cheese shredded
Instructions
- Add the water, pasta, salt and butter to the Instant Pot and give everything a gentle stir.
- Set the Instant Pot to ‘Manual’ or ‘Pressure Cook’, ‘High Pressure’ for 2 minutes.
- While the pasta cooks, shred the four cheeses.
- Once cooking has completed, allow for a 2 minute NPR (Natural Pressure Release). This will let the pasta continue cooking while any foam that built up inside the pot settles. This helps prevent a mess when releasing the pressure.
- After the 2 minute NPR has completed, do a slow and controlled pressure release. This can be done by giving the pressure release valve a half turn instead of opening it up all the way. Once the pressure has been released and the float valve has dropped, carefully open your pot and add the remaining ingredients. Alternatively, you can use my Flip-The-Trivet for Mess-Free Pasta Method.
- Add the evaporated milk to the pasta and mix.
- Add the ground mustard and shredded cheeses. Mix all the ingredients into the pasta until all the cheese melts.
- Serve and enjoy!

Notes
Use as a base for other meals. You can use this mac and cheese as a base for other meals as well. Add some tuna and peas and you’ve got Tuna Mac. Add chicken, cubed ham, diced tomatoes, crab, really so many things you can add to it! We love topping I with bacon bits! It adds the perfect finishing touch!
This sounds like something my kids will love! I would like to add peas (deep frozen) and was wondering if I can add them to the pasta to cook together?
Hi Iris! I think that would work just fine! Good way to get some veggies in there! Let me know how it turns out!
I added diced precooked ham and frozen peas after pasta cooked to pressure and stirred it up with evaporated milk/cheeses/mustard. Then set the IP on warm and it was divine!!
That sounds delicious Cristen!! Now I want to go make some!! Happy New Year and thanks for stopping by!!
This was amazing! Even the kids enjoyed it! 🙂
So happy to hear that Robyne!! Thanks for stopping by!
This is a great idea, no straining and all in one pot too!
Hi Joan! Yes, definitely won’t go back to boxed mac n cheese!!
this is very similar to Alton Brown’s stovetop mac n cheese. It’s faster though.
Hi Judith! I haven’t seen Alton’s recipe, I’ll have to check it out!
Mac and cheese real quick and not from a box.
Hi Raelynn! Yes, and it’s so much tastier!
Loved the Mac and cheese! Have you tried freezing the leftovers?
So glad you loved it!! I never have leftovers because I have 5 kids!! Let me know if you decided to freeze how it turns out! Happy New Year!
I literally just got home from the grocery store with all the cheeses to make this! I open my macaroni container, it is empty 🙁 I know you said small elbow is best, do you think fusilli pasta would be a complete fail? Or should I just wait until I have macaroni?
Hi Charlene! It should be just fine! We achieved the best consistency with small elbows but other pasta should be fine! Hope you love it!! Happy New Year!
Do you think gluten-free pasta would work the same?
Hi Patty!! I have never cooked gluten free pasta. I can’t tell
you for sure about cooking times. The cheeses and other ingredients, of course will be just fine, but you’ll have to try the pasta to see if it comes out to your liking. Please let me know if you do try it whether it works out so I know the answer!
Has there been any further feedback an the question of using gluten free noodles?
Hi Amy! I haven’t heard anything else but from what I read about GF pasta in the Facebook Instant Pot group, most people recommend cooking it for less time. My recipe calls for such little cooking time, that I would venture to say you should try it as is and see if it works out. Remember you won’t be adding the cheeses or milk until you’re done cooking the pasta, so I’d say it’s worth a try. Let me know how it goes!!
I’ve HATED homemade mac n cheese all my life. I was so skeptical about this. Oh my gosh. Yes. This was amazing!!
Yay Michelle!! This makes me so happy! Glad you tried it and loved it! Have a Happy Thanksgiving week!
Will this still work if I cut this recipe completely in half? I only have a 6qt.
Hi Vicky! The recipe should work just fine as it is in your 6 qt. If you still would like to half the recipe though, I don’t see why it wouldn’t work. Do not adjust the cooking time though. Hope this helps.
