Step-by-Step Instructions
1. Sauté Aromatics (Optional but Recommended)
Heat olive oil in a large skillet over medium heat. Sauté the chopped onion until it’s softened, about 5-7 minutes. Stir in the minced garlic and grated ginger and cook for another minute until fragrant. This step deepens the flavor of your curry.
2. Combine Ingredients in Slow Cooker
Transfer the sautéed aromatics to your slow cooker if you used a skillet. Add the rinsed lentils, diced tomatoes (undrained), coconut milk, vegetable broth, curry powder, cumin, turmeric, and cayenne pepper (if using). Stir everything well to combine.
3. Cook Your Curry
Cover your slow cooker and cook on high for 3-4 hours, or on low for 6-8 hours. The lentils should be tender when done. Cooking times can vary, so check for tenderness.
4. Stir in Spinach and Season
About 15 minutes before serving, stir in the fresh spinach. The heat from the curry will wilt it quickly. Taste and adjust the salt and black pepper as needed.
5. Serve and Enjoy Your Healthy Crock Pot Dinner
Serve your Slow Cooker Vegetarian Lentil Curry warm with rice, naan bread, or a side salad. Garnish with fresh cilantro if you like.
Variation Ideas
- Add diced sweet potatoes or carrots along with the lentils for extra vegetables.
- Stir in a squeeze of fresh lime juice at the end for a bright, tangy finish.
- Top with a dollop of plain Greek yogurt for creaminess.
- For more protein, add a can of chickpeas (drained and rinsed) during the last hour of cooking.

Store leftover Slow Cooker Vegetarian Lentil Curry in an airtight container in the refrigerator for up to 3-4 days. You can also freeze portions for up to 3 months. Reheat gently on the stovetop or in the microwave, adding a splash of water or broth if it’s too thick.
Frequently Asked Questions (FAQ)
Can I use red lentils instead?
While you can, red lentils tend to break down much faster and can make the curry very mushy. Brown or green lentils hold their shape better in the slow cooker.
Is this curry spicy?
The level of spice depends on the type of curry powder you use and if you add cayenne pepper. You can adjust the amount of spices to your preference.
Can I make this on the stovetop?
Yes, you can. Sauté the aromatics, add all other ingredients (except spinach), bring to a simmer, then cover and cook for about 30-40 minutes until lentils are tender. Stir in spinach at the end.
What can I serve with this curry?
It’s excellent with brown rice, quinoa, naan bread, or a simple green salad.
Do I need to soak the lentils?
