I created this recipe for my client GO VEGGIE. Thank you for supporting the brands that keep me inspired in the kitchen.

I’ve been in a big Tex-Mex mood lately. Sorry, not sorry.

This Instant pot chili mac is comfort food at its best. It’s full of pasta, fire-roasted tomatoes, beans, corn, and two kinds of cheese for extra cheesy goodness. Plus it’s made in an Instant Pot!

This is an easy one-pot meal to make on a busy weeknight.

It also makes a ton of leftovers to enjoy throughout the week and it reheats well.

How to make instant pot chili mac

To build a great base of flavor, start by sauteing onion, garlic, and jalapeno in some olive oil.

Once the vegetables are soft, add the pasta, vegetable stock, beans, and tomatoes. Lock the lid of your pressure cooker (make sure it’s set to sealing!) and turn it on high pressure for 4 minutes. It will take about 10 minutes for the pot to come to pressure, but compared to the time it takes to bring a big pot of water to a boil for pasta, you’re still getting a good deal here.

When the timer goes off, release the pressure manually and add the corn.

Now comes the good part: stir in all of that delicious cheese. Lactose-free GO VEGGIE cheese always melts really well, but it’s especially impressive when you stir it into super hot ingredients like these. It melts into the pasta and gets all stretchy and gooey and awesome.  

If you don’t have an Instant Pot, you can also make this recipe on the stove top. Follow the same steps below, but bring the mixture to a boil after you add the vegetable broth. Simmer the pasta for 8 minutes, or until cooked al dente.
