How This Slow Cooker Lentil Chili Saved Our Lazy Weekend
Last weekend, we were both down for the count. I was fighting a cold, and Josh was still hobbling on crutches after tearing his MCL skiing. Our two-year-old Caleb offered to make quesadillas for dinner. Tempting, but a toddler and a gas stove? No thanks. Josh, who’s been on a slow cooker kick, suggested we make this slow cooker lentil chili. I was happy to let the crockpot do the work. We chopped the veggies, dumped everything in, gave it a stir, and walked away. A few hours later, we filled our bowls and ate while watching football. The lentils gave the chili a hearty texture that felt like a real meal. It’s vegan and gluten-free, but Josh went back for a second bowl. I topped mine with avocado slices, which made it even better.
3 Reasons You’ll Love This Vegan Lentil Chili
- Lentils cook up tender and soak up all the smoky chili flavor, so you don’t miss the meat at all.
- You only need 10 minutes to prep, then the slow cooker handles the rest while you go about your day.
- It’s a blank canvas for toppings, avocado, cilantro, a squeeze of lime, or even shredded cheese if you’re not vegan.
Key Ingredients for This Healthy Lentil Chili
- Brown lentils: They hold their shape after long cooking but still get creamy. No need to soak. Look for bags that are free of debris.
- Chili powder: A blend of ground chiles, cumin, garlic, and oregano. Use a good-quality one for the best flavor. You can adjust the amount to your heat preference.
- Canned tomatoes: I like using fire-roasted diced tomatoes for a smoky depth. Regular diced tomatoes work too. Don’t drain them, the liquid helps cook the lentils.
Kitchen Tools for Slow Cooker Lentil Chili
- Slow cooker (6-quart or larger)
- Cutting board and sharp knife
- Can opener
- Measuring spoons and cups
- Wooden spoon for stirring
Tips for Making the Best Crockpot Lentil Chili
No need to pre-cook the lentils. Just give them a quick rinse and add them straight to the pot. Brown lentils hold their shape well and turn tender after 4 hours on high or 6 on low.
Taste the chili before serving and adjust salt. Lentils absorb salt as they cook, so you might need a little more than you expect. If the chili seems too thick, stir in a splash of vegetable broth.
How to Adjust the Consistency of Your Lentil Chili
Lentil chili can turn out thicker or thinner depending on how long it cooks and how much liquid the lentils absorb. If it’s too thick for your taste, stir in extra vegetable broth, a quarter cup at a time, until it reaches the consistency you like. If it’s too thin, mash some of the lentils against the side of the pot with a spoon. This releases their starch and naturally thickens the chili. You can also let it cook uncovered on high for an extra 30 minutes to reduce the liquid.
Easy Lentil Chili Variations to Try
This lentil chili is easy to adapt. If you want a non-vegan version, brown ground beef or turkey with the onions before adding everything to the slow cooker. Swap the red beans for black beans or pinto beans. Add a can of corn for extra sweetness. For more heat, leave the seeds in the jalapeño or add a pinch of cayenne. You can also cook this on the stovetop: sauté the veggies, add the rest, and simmer for 30-40 minutes until lentils are tender.
Best Toppings and Sides for Lentil Chili
Serve this chili with your favorite toppings. I love a few slices of creamy avocado, a dollop of vegan sour cream or Greek yogurt, and a sprinkle of fresh cilantro. A squeeze of lime brightens everything up. For sides, try cornbread, tortilla chips for dipping, or a simple green salad. The chili is hearty enough to eat on its own, but those extras make it a meal.
How to Store Leftover Lentil Chili
Let the chili cool completely, then transfer it to an airtight container. It will keep in the fridge for up to 5 days. The flavors get even better overnight.
How to Freeze Lentil Chili for Later
This chili freezes beautifully. Portion it into freezer-safe bags or containers, leaving some room for expansion. It will keep for up to 3 months. Thaw in the fridge overnight before reheating.
How to Reheat Lentil Chili
Reheat the chili in a pot over medium heat, stirring occasionally. Add a splash of broth or water if it has thickened too much. You can also microwave individual portions in 30-second bursts, stirring between each.
Frequently Asked Questions About Lentil Chili
Can I use green lentils instead of brown?
Yes, green lentils work well too. They hold their shape slightly better than brown lentils, so the chili will have a firmer texture. Cooking time remains the same.
Do I need to soak the lentils first?
No, brown lentils do not require soaking. Just rinse them and add them directly to the slow cooker. They will cook perfectly in the 4-6 hour window.
Can I make this chili spicier?
Absolutely. Leave the seeds in the jalapeño, add an extra jalapeño, or stir in a teaspoon of chipotle powder or cayenne pepper at the start.
Is this chili gluten-free?
Yes, as long as you use certified gluten-free vegetable broth and check that your chili powder blend doesn’t contain any wheat-based additives. All other ingredients are naturally gluten-free.
