Instructions

Step 1: Prep the Vegetables

• Wash all your vegetables thoroughly.
• Dice the onion, bell peppers, carrots, celery, and zucchini into bite-sized pieces.
• Mince the garlic finely so it spreads flavor evenly throughout the chili.
  Pro Tip: Try to cut vegetables into similar sizes so they cook evenly in the crockpot.

Step 2: Sauté the Aromatics (Optional but Recommended)

• Heat olive oil in a skillet over medium heat.
• Add the diced onion and cook for 3–4 minutes until slightly softened.
• Stir in the garlic and cook for another 30 seconds until fragrant.
• Add bell peppers, carrots, and celery and sauté for 3–5 minutes to bring out their natural sweetness.
  Pro Tip: This step deepens flavor, but if you’re short on time, you can skip and add everything directly to the crockpot.

Step 3: Combine Ingredients in the Crockpot

• Transfer the sautéed vegetables into the crockpot.
• Add zucchini, diced tomatoes, tomato sauce, drained beans, corn, and vegetable broth.
• Sprinkle in chili powder, cumin, smoked paprika, cayenne (if using), salt, and pepper.
• Give everything a good stir to combine.
  Pro Tip: Taste your liquid and adjust seasoning lightly—flavors intensify as it cooks.

Step 4: Cook the Chili

• Cover the crockpot with its lid.
• Cook on low for 6–8 hours or high for 3–4 hours, depending on your schedule.
• Give it a stir halfway through if you remember, but it’s not strictly necessary.
  Pro Tip: For extra thick chili, remove the lid during the last 30 minutes to let some liquid evaporate.

Step 5: Finish and Serve

• Taste and adjust seasonings, adding more salt, pepper, or chili powder if needed.
• Ladle into bowls and add optional garnishes like cilantro, avocado, shredded cheese, or a dollop of Greek yogurt.
• Serve warm with cornbread, tortilla chips, or a simple green salad.

Tips and Tricks for Success

• Use a full-size crockpot to avoid overcrowding; ingredients cook more evenly.
• For richer flavor, sauté the vegetables before adding them to the crockpot.
• Taste and adjust seasonings at the end—beans absorb spices, so you might need a little extra salt or chili powder.
• If you like your chili thicker, remove the lid during the last 30 minutes of cooking.
• Let the chili rest for 10–15 minutes after cooking; flavors meld beautifully during this time.

Ingredient Substitutions and Variations

• Swap black beans, kidney beans, or pinto beans with chickpeas or lentils for a different texture.
• Replace zucchini or bell peppers with mushrooms, sweet potatoes, or butternut squash.
• Use fire-roasted or plain diced tomatoes depending on your flavor preference.
• Add quinoa, farro, or barley for a grain boost and extra heartiness.
• For a spicier chili, include chipotle in adobo or jalapeños.
• Make it creamy by stirring in coconut milk or cashew cream at the end.

Serving Suggestions

• I love serving this crockpot vegetarian chili with warm cornbread—it soaks up all the delicious sauce perfectly!
• Top a bowl with avocado slices and a sprinkle of cilantro for a fresh, creamy twist.
• Serve over steamed rice or quinoa to make it extra hearty for a filling weeknight dinner.
• Spoon it into taco shells or burrito bowls for a fun, customizable meal.
• Pair with tortilla chips or crusty bread for dipping—it’s my go-to comfort combo on chilly evenings.

Storage and Reheating Instructions

• Refrigerate: Store chili in an airtight container for up to 4–5 days.
• Freeze: Freeze in portioned containers for up to 3 months—perfect for meal prep.
• Reheat on Stove: Warm gently over medium heat, stirring occasionally until heated through.
• Reheat in Microwave: Place in a microwave-safe bowl, cover loosely, and heat in 1–2 minute intervals, stirring in between.
• Tip: Chili often tastes even better the next day, once the flavors have had time to meld!
