Cream of Zucchini Soup with Crispy Lentils

This Cream of Zucchini Soup with Crispy Lentils has everything I like in a creamy vegetable soup, plus a crunchy topping that keeps things interesting. Zucchini, leek, onion, garlic, and apple are simmered with oat cream until tender, then blended until silky smooth. Meanwhile, lentils roast in the oven with olive oil and nutmeg until crisp around the edges. Spoon those over the top and you've got a simple soup with plenty of texture and cozy flavor.

What You’ll Need to Make Cream of Zucchini Soup with Crispy Lentils

• 13.4 ounces (380 g) cooked lentils, drained and rinsed
• ¼ teaspoon ground nutmeg
• 2 tablespoons olive oil, divided
• Salt, to taste
• Black pepper, to taste
• 1 garlic clove, chopped
• 1 medium zucchini, trimmed and cut into half-moons
• ½ onion, chopped
• 1 leek, white part only, cleaned and chopped
• 1 apple, cored and chopped
• 6.8 fluid ounces (200 ml) oat cream

What You’ll Need to Do

• Prep Time: 15 minutes
• Cook Time: 25 minutes
• Total Time: 40 minutes
• Serves: 4

1. Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
2. Spread the drained lentils onto a few sheets of paper towel, then place another sheet over the top. Press gently to remove as much excess moisture as possible without crushing them.
3. Transfer the lentils to the prepared baking sheet. Add the nutmeg, 1 tablespoon olive oil, and a little salt and black pepper.
4. Toss everything together, then spread the lentils into a single layer.
5. Bake for 15–20 minutes, stirring halfway through, until the lentils are drier and lightly crisp around the edges.
6. While the lentils are roasting, heat the remaining 1 tablespoon olive oil in a large pot over medium heat.
7. Add the chopped garlic and cook for 1–2 minutes, just until fragrant.
8. Add the zucchini, onion, leek, apple, and a small pinch of salt.
9. Cook for about 5–6 minutes, stirring regularly, until the vegetables begin to soften.
10. Pour in the oat cream and water, then crumble in the vegetable stock cube.
11. Season with black pepper and a little more salt if needed, then stir everything together.
12. Cover the pot and bring the soup just to a boil.
13. Reduce the heat to medium-low and simmer for about 10 minutes, or until the vegetables and apple are completely tender.
14. Remove the pot from the heat and blend with an immersion blender until the soup is smooth and creamy.
15. Taste and adjust the salt and black pepper if needed.
16. Divide the soup between four bowls and top generously with the crispy lentils.
17. Serve warm.

Easy Ingredient Swaps

Oat cream: Coconut cream, cashew cream, or another plant-based cooking cream can work.

Zucchini: Yellow summer squash is an easy substitute.

Apple: Pear can be used for a similarly mild sweetness.

Leek: Add a little extra onion if you don't have leek.

Lentils: Green or brown cooked lentils work best because they hold their shape.

Nutmeg: A little smoked paprika or cumin can give the lentils a completely different flavor.

Vegetable stock cube: Use prepared vegetable broth and reduce the added water accordingly.

Some Twist and Tweak Ideas

Add a handful of spinach before blending for extra greens.

Roast a few pumpkin seeds with the lentils for even more crunch.

Add fresh thyme to the vegetables while they cook.

Stir in a little lemon juice after blending to brighten the soup.

Add a pinch of chili flakes for some heat.

Use curry powder instead of nutmeg on the lentils for a warmer spiced version.

Top each bowl with fresh parsley or chives.

A spoonful of dairy-free yogurt can add even more creaminess.

Some Helpful Tips

Dry the lentils well. Moist lentils steam instead of crisping.

Spread them out. A single layer gives the lentils the best chance of developing crispy edges.

Don't expect chickpea-level crunch. Roasted cooked lentils become drier and crisp around the edges, but they won't all turn completely crunchy.

Clean the leek carefully. Dirt loves hiding between those layers.

Cut the vegetables fairly evenly. They'll soften at roughly the same rate.

Don't overdo the salt at the beginning. Stock cubes can already contain plenty of sodium.

Blend carefully. If you're using a countertop blender instead of an immersion blender, allow the soup to cool slightly and blend in batches.

Why Add Apple to Zucchini Soup?

The apple isn't there to make the soup taste like dessert.

It adds a mild sweetness that works nicely with zucchini, leek, and onion and helps round out the savory flavors.

Once everything is blended together, you shouldn't get an obvious apple flavor. Instead, the soup simply tastes a little fuller and more balanced.

Some Budget-Friendly Tips

Use whichever cooked lentils are cheapest, whether they're canned, vacuum-packed, or cooked from dried lentils at home.

Cooking dried lentils yourself is usually the lowest-cost option.

Regular onion can replace the leek if needed.

Use an inexpensive apple variety rather than a premium snacking apple.

Frozen chopped zucchini can also work if fresh zucchini is expensive, although the soup may need a little less water.

Store-brand oat cream and vegetable stock are perfectly fine here.

Make-Ahead Tip

The soup itself is very easy to make ahead.

Cook and blend it, let it cool, then refrigerate it in an airtight container.

I recommend making the crispy lentils separately and storing them away from the soup so they don't soften.

Reheat the soup when needed and add the lentils just before serving.

Some Storage and Reheating Tips

Store leftover soup in an airtight container in the refrigerator for up to 4 days.

Keep the crispy lentils in a separate container.

Reheat the soup gently on the stovetop over medium-low heat, stirring occasionally.

If it becomes too thick after refrigeration, add a splash of water or oat milk.

The soup can also be reheated in the microwave.

For the lentils, a few minutes in a hot oven or air fryer can help bring back some of their crispness.

The blended soup can be frozen for up to 2 months, although the texture of oat cream may change slightly after thawing.

Final Thoughts

This Cream of Zucchini Soup with Crispy Lentils takes a mild vegetable like zucchini and turns it into a creamy, satisfying bowl with plenty going on.

The leek, onion, garlic, and apple build the flavor underneath, oat cream makes everything silky, and those nutmeg-spiced lentils add the texture that creamy soups sometimes miss.

It's straightforward enough for an everyday lunch but interesting enough that it doesn't feel like just another blended vegetable soup.
