I know lots of kids are back to school already, but here we still have a few weeks to go.

I’m starting to get the itch to go back to regular weeknight meals, dinners around the table (not that I’m hating on our daily picnics!), early bedtimes and routine. Anyone else?

We’re no stranger to chili mac around here, and it’s one of our favorite meals!

What to love about chili mac:

  • It’s hearty — with ground beef, beans, and whole grain macaroni it’s got loads of fiber and protein to keep everyone going when life is crazy.
  • It’s comforting — perfect for a rainy day, a cloudy day, or just a day when only cheesy carbs will do
  • It’s easy — with just a couple things to chop and brown, it’s a true one pot meal made completely in the Pressure Cooker in just a couple minutes!
  • This Instant Pot version is mostly hands off (after the browning) and cooks in 2 minutes, meaning you can set it and forget it for a few minutes while you put your feet up!

Tips for making Instant Pot pasta:

Since I started making pasta in the Instant Pot I haven’t gone back! It’s so quick and totally hands off, making for easy one pot pressure cooker meals on a regular basis.

There are a few tricks to it though, and I’ve found that a lot of recipes call for way too long a cook time for pasta, resulting in an unappetizing mushy mess and then people are hesitant to try again.

Let me tell you, it can be done, and it can be done well! The secret?

A shorter cook time.

I understand the general rule of them is half of the cook time listed on the box.

I’m going to be bold enough here to say that I think this is, in fact, generally incorrect. That cook time is way too long.

For most short cuts of pasta, 2 minutes is plenty, and if you like your pasta very al dente, even 1 minute is likely enough for some cuts.

How to lighten up this Instant Pot Chili Mac:

  • Use ground turkey instead of ground beef for a lighter meal
  • Up the veggies — try adding mushrooms, chopped carrots, more peppers, zucchini, really anything you think would go well! The cook time is short enough that most chopped veggies will be fine.
  • Use low fat cheese instead of full fat cheese

Tools you’ll need for this Instant Pot recipe:

  • I use a 6 quart Instant Pot with bluetooth for most of my recipes — I know that things sometimes cook differently in the 8 quart.
  • You’ll need some good hard utensils to scrape the bottom after browning to ensure you don’t get a burn message. I love a good wooden spoon!

Cuisine American
Course Main Course
Servings 6 1 1/3 cup servings
Calories 590kcal

Ingredients

  • 1 lb lean ground beef
  • 1 medium onion finely chopped
  • 1 red bell pepper finely chopped
  • 1 tablespoon chili powder (2 if you like it spicy!)
  • 1 1/2 teaspoons salt
  • 1 teaspoon minced garlic
  • 1/4 teaspoon cumin
  • 3 cups low sodium beef or chicken broth
  • 1 can red kidney beans or black beans rinsed
  • 1 1/2 cups tomato pasta sauce
  • 340-375 grams whole grain macaroni (about 12-13oz)
  • 1/2 cup low fat milk
  • 3 cups shredded cheddar cheese

Instructions

  • Turn the Instant Pot to saute. Cook ground beef, onion and red pepper until beef is browned. Drain any juices.
  • On saute, add chili powder, salt, garlic and cumin. Cook and stir 1 minute. 
  • Add broth and scrape the bottom to ensure any stuck on bits are removed.
  • Turn Instant Pot off and stir in beans.
  • Top with pasta sauce (spread over the top but don’t stir) and macaroni. Press pasta down into the liquid and spread into an even layer, but don’t stir. 
  • Put the lid on, turn the valve to sealing, and select Pressure Cook or Manual for 2 minutes. 
  • When the cook time is over, do a controlled release of the pressure (slowly release the pressure by holding the valve slightly open but not all of the way).
  • Remove the lid and stir — some macaroni may appear dry or stuck together but once you stir it will be perfect. 
  • Stir in milk and cheese until cheese is melted. Serve.

    I made this for dinner tonight, I was a little gun-shy as the last time I tried pasta in my IP it was waaaaay over cooked and icky. This turned out amazing! The flavor was incredible and the pasta was perfect. Thank You for a quick and super tasty meal!

  2. Corrie says

    Yu,, yum, yum! We measured nothing, and used a whole bag of maraconi and upped the tomato sauce. Perfectly al dente.

  3. Heatherly says

    This was so easy to make and it turned out so good! I didn’t have any dairy milk on-hand so I used a combination of 2% Greek yogurt thinned down with unsweetened cashew milk and the consistency was perfect. Thanks for such a great recipe!

  4. Mary Fry says

    My 12 year old winced when he saw me cutting up the red pepper. “Is that for dinner?”
    He had 2 heaping bowls.
    It was delicious! Thank you! I’ve made several of your recipes and all have been great. The pot roast is to die for!
