Description
Tomato Soup gets a hearty upgrade with protein-rich lentils for a cozy, weeknight-ready bowl. Gently spiced, brightened with lemon, and finished with herbs and olive oil, it delivers velvety comfort in about 40 minutes. Flexible with lentil types and spices, budget-friendly, and great for leftovers.
Ingredients
2 tbsp olive oil, plus 2–3 tbsp for finishing
1 medium yellow onion, finely chopped
2 medium carrots, diced
2 celery ribs, diced
3 garlic cloves, minced
1 tsp ground cumin
1 tsp smoked paprika
1/2 tsp dried oregano
1/4 tsp red pepper flakes (optional)
1 1/4 cups red lentils or 1 cup brown lentils, rinsed
1 can (28 oz) crushed tomatoes
4 cups low-sodium vegetable broth (plus more as needed)
1 bay leaf
1 tsp fine sea salt, plus more to taste
Black pepper, to taste
1–2 tsp sugar or maple (only if tomatoes taste overly acidic)
1 lemon (zest and 2–3 tbsp juice)
1/4 cup chopped fresh basil or parsley, plus extra for serving
Instructions
Heat & soften (5–7 min): Warm 2 tbsp olive oil in a 4–5 qt pot over medium heat. Add onion, carrots, and celery with a pinch of salt. Cook until translucent and lightly sweet.
Bloom aromatics (1 min): Stir in garlic, cumin, smoked paprika, oregano, and red pepper flakes; cook until fragrant.
Build the soup: Add rinsed lentils, crushed tomatoes, broth, bay leaf, 1 tsp salt, and black pepper. Stir to combine.
Simmer (15–25 min): Bring to a gentle boil, then reduce to a steady simmer. Cook uncovered, stirring occasionally, until lentils are tender—about 18 min for red (creamier) or ~25 min for brown (more bite). Add broth if it’s thicker than you like.
Balance: Taste; if sharp, add 1–2 tsp sugar or maple.
Finish (2 min): Remove bay leaf. Stir in lemon zest and 2 tbsp juice, then herbs. Drizzle with 2–3 tbsp olive oil.
Taste & rest (2–3 min): Adjust salt, pepper, and lemon. Let stand briefly so flavors settle.
Notes
What each ingredient does: Oil blooms spices; onion/carrots/celery add sweet-savory base; garlic lifts; cumin/paprika/oregano add warmth; flakes add heat; lentils give body and protein; tomatoes form the base; broth keeps things gentle; bay is subtle; sugar softens acidity; lemon brightens; herbs freshen; finish oil adds gloss.
Must-have vs flexible: Musts = lentils, tomatoes, broth, onion/garlic, lemon, salt. Flexible = carrots/celery, specific spices, fresh herbs.
Pro tip: Use low-sodium broth so you can dial in seasoning at the end.
Substitutions: Onion ↔ leeks/shallots; extra carrots if no celery. Red lentils (15–20 min, creamier) or brown (25 min, hold shape). Add spinach in last 5 min; or 1/2 cup tiny pasta and simmer to tender. Swap olive oil with avocado oil.
Equipment: 4–5 qt pot or Dutch oven; optional immersion blender for partially blending a cup or two.
Make-ahead & storage: Keeps 3–4 days chilled; freezes up to 3 months. It thickens as it sits—loosen with broth when reheating.
Lighter/Creamier: Lighten by starting with 1 tbsp oil and finishing with extra lemon; creamier by blending part of the soup or stirring in 1/3 cup unsweetened coconut milk off heat.
Toppings: Garlic croutons, toasted pepitas, chili oil, lemon zest, extra herbs.
Sides: Warm flatbread, crusty GF baguette, arugula salad with lemon and oil.
Scaling: Double in a 6–7 qt pot; add 3–5 extra minutes of simmer and broth as needed.
Troubleshooting: Too salty—add broth, a small diced potato to simmer and remove, or lemon. Too bland—salt in pinches, add lemon/herbs; bloom a pinch more paprika in oil. Too watery—simmer uncovered or blend a cup. Overcooked lentils—add greens and lemon; finish with oil.
FAQs: Frozen/precut veg are fine; red vs brown lentils both work; add broth as it sits; naturally dairy-free & gluten-free; keeps 3–4 days, freezes 3 months.
