Lemon Garlic Lentil & Potato Soup

Lemon Garlic Lentil & Potato Soup brings tender lentils, buttery Yukon Gold potatoes, spinach, and plenty of vegetables together in a bright, hearty broth. It has all the comfort of a cool-weather soup without becoming heavy.

Garlic, cumin, coriander, and thyme build the savory base, while the lentils simmer directly in the broth until tender. Yukon Gold potatoes add substance and naturally soften the broth as they cook. Fresh spinach goes in near the end, keeping its fresh color and delicate bite.

The finishing touch is a quick garlic-herb breadcrumb topping. It adds crisp contrast to the tender lentils and potatoes, while fresh lemon juice wakes up the entire pot just before serving. Spoon the crumbs over each bowl at the table so every serving keeps that satisfying crunch.

Recipe Yield: 6 servings

INGREDIENTS

1 1/2 cups brown or green lentils, rinsed and drained
1 lb Yukon Gold potatoes, cut into 3/4-inch pieces
4 packed cups baby spinach
1 medium yellow onion, diced
2 medium carrots, peeled and diced
2 celery ribs, diced
5 garlic cloves, finely minced and divided
6 cups low-sodium vegetable broth
1 tsp ground cumin
1/2 tsp ground coriander
1/2 tsp dried thyme
1 1/2 tsp kosher salt, divided, plus more to taste
1/2 tsp black pepper
2 tbsp extra-virgin olive oil
1 bay leaf
1 large lemon
1/4 cup chopped fresh parsley, divided
1 tbsp extra-virgin olive oil
1/2 cup panko breadcrumbs
1/4 tsp garlic powder

INSTRUCTIONS

1. Soften the vegetables:
Heat 2 tbsp olive oil in a large Dutch oven over medium heat. Add the onion, carrots, celery, and 3/4 tsp salt. Cook for 6–8 minutes, stirring occasionally, until softened.

2. Add the aromatics:
Stir in 4 minced garlic cloves, cumin, coriander, thyme, and black pepper. Cook for 30 seconds, stirring constantly, until fragrant.

3. Build the soup:
Add the lentils, potatoes, vegetable broth, bay leaf, and 1/2 tsp salt. Stir well and bring to a gentle boil.

4. Simmer until tender:
Reduce the heat to medium-low and partially cover the pot. Simmer for 28–35 minutes, stirring occasionally, until the lentils are tender and the potatoes pierce easily with a fork.

5. Make the garlic crumbs:
Meanwhile, heat the remaining 1 tbsp olive oil in a small skillet over medium-low heat. Add the panko and cook for 2–3 minutes, stirring frequently, until lightly golden. Add the remaining minced garlic clove, garlic powder, and remaining 1/4 tsp salt. Cook for 30–60 seconds, stirring constantly, until fragrant and crisp.

6. Finish the crumbs:
Remove the skillet from the heat. Stir 1 tbsp parsley into the toasted breadcrumbs and set aside.

7. Add the spinach:
Remove and discard the bay leaf. Stir the spinach into the soup and cook for 1–2 minutes, just until wilted.

8. Add the lemon:
Finely grate 1 tsp lemon zest, then squeeze 3 tbsp fresh lemon juice. Remove the soup from the heat and stir in the lemon zest, lemon juice, and remaining 3 tbsp parsley.

9. Adjust the broth:
Let the soup stand for 3 minutes, then stir. Add a small splash of warm broth or water if you prefer a looser consistency. Taste and adjust the salt or lemon juice as needed.

10. Finish and serve:
Ladle the soup into bowls. Sprinkle the garlic-herb breadcrumbs over each serving immediately before eating so they stay crisp.

Helpful Tips to Perfect This Recipe

• Use brown or green lentils: They become tender while still holding their shape. Red lentils break down much more quickly and create a very different consistency.
• Cut the potatoes evenly: Keeping the pieces close to 3/4 inch helps them become tender at roughly the same time as the lentils.
• Add lemon after cooking: Fresh lemon loses some brightness when simmered too long. Adding the juice and zest off heat keeps the soup lively.
• Keep the crumbs separate: Add the garlic breadcrumbs only when serving. Storing them separately keeps their crisp finish intact.
