My family loves pasta for dinner, and some of our favorite pasta recipes include Instant Pot Spaghetti, Lasagna, Instant Pot Mac and Cheese and this comforting chili mac recipe. If you’d like a slow cooker version of this chili mac and cheese, my Slow Cooker Vegetarian Chili Mac is a reader favorite.

The pasta absorbs delicious flavor as it cooks in the pot with the tomatoes, veggies and seasonings. The tomato-based sauce is slightly spicy, and you can easily adjust the spice level to your tastes. If you want to add ground beef or turkey to this recipe, I’ve included tips for that below.

Ingredients

ingredients for vegetarian chili mac

  • Olive Oil: Olive oil is used when sautéing the vegetables.
  • Onion, Bell Pepper & Carrots: This trio of healthy veggies provide flavor and nutrition. Chop the veggies into small pieces, no bigger than 1/4-inch, so that they will become tender in the time it takes the pasta to cook.
  • Garlic & Seasonings: Fresh garlic, chili powder, cumin and salt add flavor to the chili mac.
  • Diced Tomatoes & Diced Tomatoes with Green Chilies: These help to create a sauce for the chili mac. The diced tomatoes with green chilies add extra flavor and some spice.
  • Elbow Macaroni Pasta: Both whole wheat and white pasta work well in this recipe.
  • Black Beans & Kidney Beans: Canned beans add filling protein to this vegetarian pasta recipe. You can use other types of canned beans if you prefer, such as pinto beans.
  • Water: The pasta will absorb the water as it cooks.
  • Shredded Cheese: Cheddar, Monterey jack and mozzarella all work well in this recipe. You can use one type of cheese or a combination. I recommend buying a block of cheese and shredding it yourself. The preshredded cheese that is sold at the store is often coated with an anti-caking agent that makes it not melt as smoothly.

Notes

  • You will need a skillet or pot that is at least 12 inches wide and 2 inches deep to fit the full recipe.
  • This recipe makes a chili mac with some spice to it. The spice is not overwhelming, but if your family prefers less spice I'd recommend using mild diced tomatoes with green chilies or subbing with a can of diced tomatoes without green chilies (fire roasted diced tomatoes would be delicious). To make the chili mac spicier, add a small amount of cayenne pepper or crushed red pepper flakes along with the other seasonings. 
  • To add meat to this recipe, add ground beef or ground turkey to the pan after sautéing the onion, carrots and bell pepper for a few minutes. Cook the meat, crumbling, until browned and then proceed with the recipe.
