Chili Mac Recipe Questions
Can I add beans to this recipe? You sure can! You can use any beans you'd use with chili. Just drain the beans and add them at the same time you add the diced tomatoes.
Can I use substitute the macaroni with other pasta? Yes, you can use other pasta shapes in chili mac. For thicker pasta (penne, rotini, rigatoni, etc), follow the recipe as it is written. For thinner pasta (classic shells, spaghetti noodles), subtract 1 minute from the pressure cook time and follow the recipe accordingly.
Does chili mac have cheese? I've made this recipe with and without it. I love it either way, but if I leave out the cheese, I like to add a little half and half to make it creamy.
Can I substitute other kinds of cheese in this recipe? Yes, you can substitute your favorite shredded cheese for the cheddar in this recipe.
Can I make chili mac ahead? Absolutely! You can make it ahead and reheat the whole pot when it's army-feeding time. Or you can meal prep it into portions and reheat as needed. Either way, to reheat chili mac, you'll want to add a splash of water, broth, or milk, and heat via stove or microwave.

- Increase heat to high and bring everything to a boil for a few minutes.

For thicker pasta (macaroni, rotini, penne), follow recipe as it is written. For thinner pasta (shells or spaghetti noodles) pressure cook the pasta for 1 minute (instead of 2 minutes) followed by the 10 minute natural pressure release. Cheese: I created this recipe with minimal cheese (1 cup). You can add more cheese or leave it out completely if you're dairy-sensitive. I sometimes like to add a splash of half and half in place of the cheese. Enjoy!
