Notes on Ingredients

Ingredients for sweet potato chili labeled on counter.

Sweet Potatoes: Use peeled, cubed orange sweet potatoes for best results.
Aromatics: A minced yellow onion and garlic are the building blocks of a good chili recipe.
Jalapeno: A finely minced, seeded jalapeno adds spice and dimension to the chili.
Bell Pepper: Use a red bell pepper as it adds a nice sweet flavor to the chili, or omit the pepper altogether if you don't care for the flavor.
Beans: I love using both black beans and kidney beans for this recipe. That said, you can swap the black beans out for additional kidney beans or vice versa.
Chili Seasoning: I use my Homemade Chili Seasoning Blend which is the perfect combination of chili powder, paprika, cumin, garlic powder, onion powder, salt, and pepper.
Chipotle in Adobo Sauce: A little bit of canned chipotle in Adobo sauce goes a long way to packing in flavor into this veggie chili. It adds smokiness and a bit of spice but does not overwhelm the flavors in the chili or make it overly spicy.
Vegetable Broth: Use your favorite low-sodium store-bought or homemade vegetable broth for this recipe. Chicken broth/stock can be used in place of vegetable broth, but the chili will no longer be vegetarian.
Tomatoes: For additional flavor and smokey undertones, use canned fire-roasted diced tomatoes. If you don't have fire-roasted tomatoes on hand, plain diced tomatoes will work.
Corn: Use either frozen corn kernels or canned corn kernels that have been rinsed and drained. The corn adds a nice sweet flavor to this Instant Pot Vegetarian Chili.
Fresh Lime: Finishing this chili with fresh lime juice is key to making the flavors all meld together and pop in your mouth. Don't overlook this addition.
Oil: Use canola, avocado, or olive oil to saute the vegetables.

Substitutions/Modifications

Control the Spice. To make this chili spicier, you can double the chipotle and/or the jalapeno. To keep this chili on the milder side, omit or cut in half the chipotle and/or the jalapeno.
Using Dried Beans: Feel free to use my recipe for Instant Pot dried beans first to cook black beans or kidney beans and then proceed with the recipe as directed.
Omit the Quinoa. If you don't care for quinoa, don't add it! Instead, double the beans and decrease the vegetable broth from 3 cups to 2 cups.
Thin it Out: This Instant Pot Vegetarian Chili is pretty thick. Feel free to increase the broth to 4 cups for a thinner chili.

How to Make Instant Pot Vegetarian Chili

The following tips are provided to help you achieve perfect results. You will find the detailed instructions in the recipe card at the bottom of this post.

Sauté the Onions and Peppers. A tip for developing great flavor in a quick-cooking, low-fat chili is to sauté the onions, peppers, and jalapeno together. This will allow the peppers and onions to develop rich, caramelized flavor and enhance their natural flavor.

Deglaze the Inner Pot. Anytime you sauté ANYTHING in an electric pressure cooker, you must add a bit of thin liquid and scrape up the browned bits on the bottom of the inner pot. This will prevent a burn notice AND add flavor to this Sweet Potato Chili.

Rinse Quinoa. Rinsing removes quinoa's natural coating, called saponin, which can make the quinoa taste bitter. Even if your quinoa states it is pre-rinsed, I would highly recommend rinsing it again by placing it into a fine-mesh strainer and running under cold tap water for 1-2 minutes.

Layer the Ingredients. Another tip to ensure you don't experience a burn notice when making Instant Pot Vegetarian Chili is to layer the ingredients in the right way. Combine the beans, corn, sweet potatoes, quinoa, and remaining seasonings with the onions and broth mixture in the inner pot. Then pour the tomatoes on top of the ingredients and DO NOT STIR.

Pressure Cook. Once the cooking time has elapsed, let the pressure release naturally for at least 10-15 minutes on its own. This will ensure everything is fully cooked and will keep the hot liquid from spewing out of the venting knob.
Season and Serve. Don't Forget the Lime Juice. Adding the juice of a lime truly takes a good chili and turns it into a phenomenal chili! Don't skip it!

Serving Suggestions

Instant Pot Vegetarian Chili is so jam-packed with flavor this there is no need to add any toppings. You can simply serve with as a hearty entree with or without homemade cornbread or sweet potato biscuits.

But no one ever complains about toppings on chili. For this Sweet Potato Chili, I recommend offering cilantro, sour cream, corn chips, diced avocado, and shredded cheese and letting people top their chili as they desire.

Storage & Reheating Instructions

Refrigerate: To store this vegetarian chili, allow it to cool slightly and then place it in an airtight container in the refrigerator for up to 5 days.
Freeze: Allow the chili to cool fully, then place it into a freezer-safe container allowing for 1 inch of room for expansion. Store the sweet potato chili in the freezer for up to 3 months.
Reheat: If needed, defrost the vegetarian chili in the refrigerator overnight. Rewarm several portions in a heavy-duty saucepan on the stove over medium heat until warmed through, adding splashes of broth or water as needed to thin the chili. Alternatively, reheat individual servings in a heat-safe bowl, in 1-minute intervals until heated through.
