If you love easy dinners, you’ll want this in your weeknight rotation.

• Budget-friendly: Lentils cost pennies and stretch a meal like a champ.
• Nutritious: High in fiber and plant protein; you get comfort and health in one bowl.
• Versatile: Swap spices, add veggies, or throw in your favorite toppings.
• Meal-prep friendly: Cooks into delicious leftovers that reheat beautifully.

Ingredients You’ll Need

Ingredient (yes, I promised a didacted part — here it is): the full list sits right below. You’ll only need one grocery run for this, I swear.

• 1 cup dried lentils (brown or green)
• 1 can (14 oz) diced tomatoes
• 1 can (15 oz) black beans, drained and rinsed
• 1 medium onion, chopped
• 2 cloves garlic, minced
• 1 bell pepper, chopped
• 2 cups vegetable broth
• 2 tablespoons taco seasoning
• 1 teaspoon cumin
• Salt and pepper to taste

Method (yes, here’s the Method part — neat and tidy): follow the step-by-step below for an effortless slow-cooker masterpiece.

How to Make (Step-by-Step)

STEP 1

Rinse the lentils and add them to the slow cooker. I rinse to remove dust and keep the texture clean. Why skip this? You shouldn’t.

STEP 2

Add diced tomatoes, black beans, onion, garlic, bell pepper, vegetable broth, taco seasoning, cumin, and salt and pepper. Layering ingredients doesn’t matter much here, but stirring helps the spices distribute evenly.

STEP 3

Stir to combine all ingredients. I stir twice — once right away and once after an hour if I pass by the kitchen. No need to obsess.

STEP 4

Cover and cook on low for 6-8 hours or on high for 3-4 hours. Lentils soften and absorb the flavors, so low and slow yields the best texture. Cooking on high works in a pinch.

STEP 5

Serve hot and enjoy as is or with your choice of toppings. I love avocado and a squeeze of lime, but more on toppings in a minute.

Pro Tips for the Best Results

• Rinse lentils to remove dust and keep the broth clear.
• Use low heat when you can; it improves texture and melds flavors.
• Adjust broth if you like thicker chili; start with 1.5 cups and add more as needed.
• Add a splash of acid (lime juice or vinegar) at the end to brighten flavors.
• Season gradually and taste near the end. Slow cooking concentrates saltiness.
• Double the batch for meal prep or freezer-friendly portions.
• Want more heat? Add chopped jalapeños or a dash of chipotle powder. IMO, chipotle adds smoky goodness.

Fun Variations & Topping Ideas

Variations:

• Swap black beans for kidney or pinto beans for a different texture.
• Add corn or zucchini in the last hour for added veg.
• Stir in a handful of chopped greens (spinach or kale) at the end for color and nutrients.
• For a smoky twist, use fire-roasted tomatoes or add smoked paprika.

Toppings:

• Avocado slices or guacamole for creaminess.
• Chopped cilantro and a squeeze of lime for freshness.
• Shredded cheese or vegan cheese if you want melty goodness.
• Sour cream or plain Greek yogurt to cool the spice.
• Tortilla chips or crushed Doritos for crunch (don’t judge me — they’re life).
• Green onions and pickled jalapeños for extra punch.

Storing and Reheating

Store leftover chili in an airtight container in the fridge for up to 4 days. For longer storage, freeze in portions for up to 3 months.

To reheat:

• Microwave: Heat in 1-minute intervals, stirring between cycles until hot.
• Stovetop: Warm in a saucepan over medium-low heat, adding a splash of broth if it feels thick.
• Slow cooker: Reheat on low for 1-2 hours if you plan ahead.

Always taste and adjust seasoning after reheating. Flavors mute in the fridge, so you might need a pinch more salt or a squeeze of lime.

Leftover ideas

• Taco night: Spoon chili into warm tortillas and top with cheese and cilantro.
• Loaded baked potatoes: Top a baked potato with chili, cheese, and green onions.
• Rice bowls: Serve over rice with avocado and hot sauce.
• Nachos: Smother tortilla chips with chili and broil with cheese until bubbly.
• Soupify it: Thin with broth and turn it into a stew for dipping crusty bread.

If you feel fancy, blend half the chili for a creamier base while keeping the other half chunky. Trust me — texture contrast wins.

Frequently Asked Questions (FAQ)

Do I need to soak the lentils before using them?

No soaking required. Lentils cook nicely without soaking, which saves you time. Just rinse them well and add directly to the slow cooker.

Can I use red lentils instead?

You can, but red lentils cook faster and break down into a softer, almost creamy texture. Use them if you want a thicker, stew-like chili.

How do I make this spicier or milder?

To make it spicier, add chopped jalapeños, crushed red pepper, or chipotle powder. For a milder version, use mild taco seasoning and skip the extra chiles. You control the heat — you’re the boss.

Can I make this in an Instant Pot instead of a slow cooker?

Yes. Cook on high pressure for about 10-12 minutes with a natural release for 10 minutes. Add a little more broth if needed, since pressure cookers don’t allow much evaporation.

Is this dish vegan?

Yes, the base recipe is vegan. Add dairy toppings if you prefer, but the chili itself stays plant-based.

A Note on Flavor Balancing (short but important)

Slow cooker dishes sometimes need a final brightener. I always add a squeeze of lime or a splash of vinegar after cooking. It wakes everything up and cuts through the richness. Want to look like a kitchen wizard in 30 seconds? Do that.
