Ingredients You'll Need
Great chili starts with great produce. Look for firm, unblemished sweet potatoes with tight skin—those gnarly ones are fine, just peel away any eyes. I prefer orange-fleshed Garnets for their creamy texture, but jewel or even Japanese purple sweet potatoes work in a pinch. Canned beans are perfectly acceptable here; rinse them under cold water to remove up to 40 % of the sodium. If you’re cooking beans from dried, you’ll need 1 ¾ cup black beans and 1 ¾ cup kidney beans, simmered until just tender. For the corn, frozen kernels are my year-round staple because they’re flash-frozen at peak sweetness. Fire-roasted diced tomatoes bring subtle charred notes, but regular diced tomatoes plus a pinch of sugar do the job. Vegetable broth should be low-sodium so you control the salt. Chipotle in adobo lends smoky depth—one pepper minced equals roughly 1 tablespoon, plus 1 teaspoon of the sauce for extra oomph. Finally, that half-shot of maple syrup isn’t for sweetness; it balances acidity and rounds out the spices, much like a baker’s pinch of sugar in tomato sauce.
How to Make Slow Cooker Black Bean and Sweet Potato Chili with Corn
Prep the aromatics
Dice the onion, seed (or don’t) the jalapeño, and mince the garlic. I like to keep the pieces on the smaller side so they melt into the chili rather than remain distinct chunks.
Load the slow cooker
Add beans, tomatoes, sweet potatoes, onion, jalapeño, garlic, corn, broth, chipotle, maple syrup, and all the spices. Stir well so every cube of sweet potato is coated; this prevents them from oxidizing and turning gray.
Choose your time
Cover and cook on LOW for 7–8 hours or on HIGH for 4 hours. I prefer low and slow; the sweet potatoes stay intact yet custardy inside.
Check for doneness
After the minimum time, spear a cube of sweet potato. It should slide off the fork with gentle pressure but not collapse into mush.
Adjust consistency
If you like a thicker chili, whisk 1 tablespoon masa harina or cornmeal with ¼ cup warm broth and stir into the pot; cover and cook 15 minutes more.
Season to taste
Add salt gradually—start with ½ teaspoon, then work up. Beans and broths vary wildly in sodium.
Serve with flair
Ladle into warm bowls and top with avocado, cilantro, lime wedges, and a shower of crushed tortilla chips for crunch.
Expert Tips
Layer heat wisely
Add half the chipotle, taste after cooking, then stir in more adobo sauce. You can’t take it out, but you can always build it up.
Freeze single portions
Use silicone muffin trays; each “muffin” equals roughly ½ cup. Pop them out and store in a zip bag for quick lunches.
Deglaze for depth
If you have an extra five minutes, sauté the onion and spices in a skillet with a splash of oil before adding to the slow cooker; it amplifies flavor.
Color retention
A squeeze of fresh lime just before serving keeps the sweet-potato cubes vibrant and prevents that drab khaki hue.
Overnight soak trick
If you decide to use dried beans, soak them with 1 teaspoon baking soda; it softens skins and shortens cooking time.
Corn char upgrade
Toss frozen corn in a dry skillet over medium-high heat until lightly blistered before adding to the crock; it adds caramelized notes.
Variations to Try
-
Summer squash swap: Replace half the sweet potato with diced zucchini; add it only in the final 45 minutes so it doesn’t disappear.
-
Midnight black version: Add 2 tablespoons cocoa powder and 1 shot espresso for a mole-inspired undertone.
-
Coconut curry twist: Swap cumin and chili powder for 2 tablespoons Thai red curry paste and use coconut milk instead of broth.
-
Extra greens: Stir in 5 ounces baby spinach during the last 5 minutes; the residual heat wilts it perfectly.
-
Meat-lover’s compromise: Brown 8 ounces chorizo, drain, and add to the cooker; reduces vegetarian yield to 5 servings.
Storage Tips
Let the chili cool completely before transferring to airtight containers. It will thicken as it sits; thin with broth or water when reheating. Refrigerated chili keeps 5 days, but flavors peak around day 2–3 once the spices have fully mingled. For longer storage, ladle into quart-size freezer bags, squeeze out excess air, and lay flat on a sheet pan until solid; stack horizontally like books to save space. Thaw overnight in the refrigerator or microwave on 50 % power, stirring every 2 minutes. When reheating on the stovetop, add a splash of fresh lime to wake up the flavors. Avoid repeated reheat cycles; portion into smaller containers so you only warm what you’ll eat.
