Instructions

Sauté aromatics

Heat olive oil in a large pot over medium heat. Add the chopped onion and sauté until translucent, about 4 minutes, then stir in minced garlic and cook an additional minute until fragrant. This builds a flavorful foundation for the soup.

Pro Tip: Use a heavy‑bottomed pot to prevent scorching.

Add vegetables & spices

Introduce diced carrots, parsnips, and potatoes to the pot, stirring to coat them with the aromatic base. Sprinkle in thyme, smoked paprika, salt, and pepper, letting the spices toast lightly for 2 minutes, which deepens their aroma and integrates flavors.

Pro Tip: Cut vegetables uniformly for even cooking.

Add lentils & broth

Add the rinsed lentils followed by the vegetable broth, stirring to combine. Increase heat to bring the mixture to a rolling boil, then reduce to a gentle simmer. This ensures the lentils begin to soften evenly while absorbing the seasoned broth.

Pro Tip: Skim any foam that rises for a clearer broth.

Simmer until tender

Cover the pot and let the soup simmer for 25‑30 minutes, stirring occasionally. Check the lentils for tenderness; they should be soft but retain shape. The vegetables will be fork‑tender, and the broth will have thickened slightly, creating a hearty texture.

Pro Tip: Remove the lid for the last 5 minutes to concentrate flavors.

Finish & serve

Remove the bay leaf, taste, and adjust seasoning with additional salt or pepper if needed. Ladle the soup into bowls, drizzle a tiny splash of olive oil, and sprinkle optional Parmesan or fresh parsley. Serve hot, accompanied by crusty bread if desired.

Pro Tip: Let the soup rest 5 minutes; flavors meld further.

Expert Tips

Tip #1: Toast the spices

Toast the spices briefly before adding broth; this releases essential oils, intensifying the soup’s aroma without extra salt. It also adds a subtle depth that plain simmering can’t achieve, especially with smoked paprika.

Tip #2: Adjust consistency

If the soup becomes too thick, thin it with extra broth or water; conversely, blend a cup of cooked lentils for a creamier texture without dairy.

Tip #3: Prep ahead

Prepare the lentils and chopped vegetables the night before; storing them in the fridge saves prep time and allows flavors to meld, making weekday cooking faster.

Storage & Variations

Cool the soup to room temperature before transferring to airtight containers. Refrigerate for up to 4 days or freeze for 2 months. For a heartier version, add diced smoked sausage or a handful of kale in the final minutes. To make it vegan, omit Parmesan and stir in nutritional yeast as a cheesy substitute. Serve with a drizzle of extra‑virgin olive oil and crusty sourdough for extra texture.
