Roasted Red Pepper Lentil Soup

The first time I made this soup, it was supposed to be a quick weeknight dinner, but the smell of those peppers roasting filled the entire apartment so wonderfully that I ended up calling a friend to come over instead.

Last winter I made a massive batch during a snowstorm and ate it for three days straight, each bowl feeling more comforting than the last.

Ingredients

• 3 large red bell peppers: Roasting transforms them into something almost sweet and smoky
• 1 medium yellow onion, diced: The foundation that holds everything together
• 2 medium carrots, diced: Adds natural sweetness and beautiful color
• 2 celery stalks, diced: Provides that classic aromatic base
• 3 garlic cloves, minced: Dont be shy with garlic here
• 1 (14 oz) can diced tomatoes: Use the juice too, it adds depth
• 1 cup dried brown or green lentils, rinsed: Red lentils work too but will make it creamier
• 5 cups vegetable broth: Homemade is best but store bought works perfectly
• 1 tbsp olive oil: For sautéing the vegetables
• 1 tsp smoked paprika: This is the secret ingredient that makes it taste special
• 1/2 tsp ground cumin: Earthy and warm
• 1/2 tsp dried thyme: Fresh is lovely but dried works beautifully
• 1/4 tsp chili flakes: Optional if you like a little heat
• 1 bay leaf: Remove before serving
• Salt and black pepper: Taste and adjust as you go
• Fresh parsley and lemon wedges: For brightness at the end

Instructions

Roast the peppers:

Preheat your oven to 425°F, cut peppers in half and remove seeds, place cut side down on a lined baking sheet, and roast for 20 to 25 minutes until the skins are blistered and charred.

Steam and peel:

Move the hot peppers into a bowl and cover it tightly, let them steam for 10 minutes, then slip off those charred skins and chop the peppers roughly.

Build the base:

Warm olive oil in a large pot over medium heat, add onion, carrot, and celery, and sauté for 5 to 6 minutes until they soften and smell wonderful.

Add the aromatics:

Stir in garlic, smoked paprika, cumin, thyme, and chili flakes and cook for just 1 minute until fragrant.

Simmer the soup:

Add the roasted peppers, diced tomatoes with their juice, lentils, bay leaf, and broth, bring to a boil, then reduce heat, cover, and simmer for 25 to 30 minutes until everything is tender.

Blend and finish:

Remove the bay leaf, blend partially with an immersion blender to keep some texture, season with salt and pepper, and serve with parsley and lemon.

Save

This recipe became my go to for bringing dinner to friends who need comforting, and I now keep little jars of roasted peppers in the freezer just for this purpose.

Making It Your Own

A splash of coconut milk stirred in at the end adds incredible richness, while a handful of spinach wilts in beautifully during the last few minutes of simmering.

Serving Suggestions

Crusty bread is non negotiable for dipping, but a simple green salad with vinaigrette cuts through the richness perfectly.

Batch Cooking Wisdom

Double this recipe without hesitation because it freezes exceptionally well and tastes even more developed after a few days in the refrigerator.

• Leave some texture when blending so it feels hearty
• Add a splash of vinegar if it needs brightness
• Taste again after reheating since flavors concentrate

Save

Theres something deeply satisfying about a soup that comes together so simply yet tastes like it simmered all day.

Recipe Questions & Answers

→ Can I make this soup ahead of time?

Absolutely. This soup actually improves after a day or two in the refrigerator as the flavors meld together. Store in an airtight container for up to 5 days and reheat gently on the stove.

→ What's the best way to roast the peppers?

Roast at 425°F cut-side down until the skins blister and char. The steaming step afterward makes peeling effortless—let them cool covered for 10 minutes, then the skins slip right off.

→ Can I use red lentils instead of brown?

Yes, red lentils work beautifully and cook faster in about 15-20 minutes. They'll create a creamier texture and slightly thicken your soup naturally as they break down during cooking.

→ How do I adjust the consistency?

For a thicker soup, blend more thoroughly or add less broth. To thin it out, simply add more vegetable broth. The immersion blender gives you complete control over texture—blend partially for chunks or fully for smooth.

→ What can I serve alongside this soup?

Crusty bread is perfect for dipping. A simple green salad with lemon vinaigrette balances the richness. You could also serve with roasted vegetables or grilled vegetables for a complete Mediterranean meal.
