This hearty lentil soup has been my family's winter staple for years. The recipe came to me from my grandmother, who perfected it over decades of cooking for our large family gatherings. What began as a simple peasant dish has evolved into a beloved tradition that brings warmth to our table during the coldest months.
I first made this soup during a particularly harsh winter storm when we were snowed in for days. With limited ingredients available, I turned to this recipe out of necessity. Now my children request it weekly, regardless of the weather outside. It has become our comfort food ritual every Sunday evening.
Ingredients
- Dried green lentils carefully sorted and rinsed thoroughly to remove any debris
- Yellow onions finely diced for a sweet aromatic base
- Carrots peeled and chopped into uniform pieces for even cooking
- Celery ribs with leaves included for additional flavor
- Garlic cloves freshly minced just before adding to preserve potency
- Crushed tomatoes San Marzano variety offers the best flavor profile
- Vegetable broth homemade if possible for deeper complexity
- Bay leaves fresh rather than dried makes a noticeable difference
- Ground cumin toasted briefly before adding for enhanced nuttiness
- Smoked paprika adds depth of flavor and subtle smokiness
- Fresh lemon juice added at the end brightens all the flavors
- Fresh parsley roughly chopped for garnish and herbaceous notes
Step-by-Step Instructions
- Prepare the Vegetables
- Dice all vegetables to similar sizes for even cooking. Take your time with this step as properly cut vegetables will cook uniformly and create a more balanced texture in the finished soup. The onions should be about a quarter inch dice, while carrots and celery can be slightly larger.
- Sauté the Aromatics
- Heat olive oil in a large Dutch oven over medium heat until shimmering. Add the diced onions and cook for 5 minutes until translucent. Then add the carrots and celery, cooking for another 4 minutes until slightly softened. Finally, add the minced garlic and cook for just 30 seconds until fragrant, being careful not to let it brown which would create bitterness.
- Toast the Spices
- Add the cumin and smoked paprika directly to the vegetable mixture, stirring constantly for one minute. This crucial step blooms the spices in the oil, releasing their essential oils and developing complex flavor compounds that would otherwise remain dormant. You should notice an immediate aroma filling your kitchen.
- Add Lentils and Liquids
- Pour in the rinsed lentils, crushed tomatoes, and vegetable broth. Add bay leaves and stir everything together thoroughly, making sure to scrape any browned bits from the bottom of the pot. These contain concentrated flavors that will enrich your soup. Bring the mixture to a gentle boil.
- Simmer to Perfection
- Reduce heat to maintain a gentle simmer and cook uncovered for 25-30 minutes. Check the lentils occasionally by sampling them. They should be tender but still hold their shape. If they begin to break down too much, your soup will become mushy rather than having distinct textures.
- Final Seasoning
- Remove from heat and discard bay leaves. Stir in fresh lemon juice and adjust salt and pepper to taste. Let the soup rest for 5 minutes before serving to allow flavors to marry and develop fully. This brief resting period makes a remarkable difference in the final flavor profile.

The smoked paprika is my secret weapon in this recipe. I discovered its transformative power after a trip to Spain where I watched local cooks using it in everything from soups to stews. When I returned home, I immediately incorporated it into my lentil soup and my family noticed the difference immediately. Even my son who claimed to dislike lentils became an instant convert after tasting this version.
Storage Tips
This soup actually improves with time as the flavors continue to develop and meld together. Store cooled soup in airtight containers in the refrigerator for up to five days. The texture may thicken slightly during storage as the lentils continue to absorb liquid. When reheating, add a splash of water or broth to reach desired consistency.
For longer storage, freeze portions in freezer safe containers leaving about an inch of headspace for expansion. The soup will maintain optimal quality for up to three months. Thaw overnight in the refrigerator before reheating gently on the stovetop, stirring occasionally to ensure even warming.
Ingredient Substitutions
This recipe welcomes adaptations based on what you have available. Red lentils can replace green but will cook faster and break down more creating a creamier texture. Brown lentils maintain their shape similarly to green and work perfectly as a direct substitute.
For a deeper flavor profile, substitute chicken broth for the vegetable broth if you are not seeking a vegetarian option. Chicken broth adds a richness that complements the earthiness of the lentils beautifully.
If fresh herbs are unavailable, dried herbs can be used at a ratio of 1 teaspoon dried for every tablespoon of fresh. Add dried herbs earlier in the cooking process to allow time for their flavors to fully release and distribute throughout the soup.
Serving Suggestions
Serve this hearty soup as a complete meal with a slice of crusty artisan bread for dipping. A dollop of tangy Greek yogurt on top provides a creamy contrast to the earthy lentils and brightens the entire dish.
For a more substantial meal, ladle the soup over a small portion of cooked brown rice or quinoa in the bottom of the bowl. This creates a complete protein and adds interesting textural elements to each spoonful.
During summer months, serve this soup at room temperature with a generous drizzle of good quality olive oil and a sprinkling of crumbled feta cheese for a Mediterranean inspired variation that works beautifully as a light dinner.
Recipe FAQs
- → Why are they called Forgotten Cookies?
They earned their name because after baking, you turn off the oven and leave (or "forget") them inside overnight. This slow cooling process creates their unique texture - crisp outside and soft inside.
- → How do I know when my egg whites are properly whipped?
For these cookies, you want stiff peaks - meaning when you lift the beater, the egg whites form peaks that stand straight up without flopping over. The mixture should feel smooth and glossy, not grainy.
- → Can I use different types of chocolate in these cookies?
Absolutely! While semi-sweet chocolate chips are traditional, you can experiment with dark chocolate for a richer flavor, milk chocolate for something sweeter, or even white chocolate for a different twist.
- → Are Forgotten Cookies gluten-free?
Yes, these cookies are naturally gluten-free as they contain no flour. Just be sure to check that your chocolate chips and any add-ins are also certified gluten-free if serving to someone with celiac disease.
- → How should I store these cookies and how long do they last?
Store Forgotten Cookies in an airtight container at room temperature for 5-7 days. They can also be frozen for up to 3 months - freeze them first in a single layer before transferring to a container to prevent sticking.
- → Why didn't my cookies develop a crisp exterior?
This could be due to excess humidity in your kitchen or oven. Try baking them on a dry day, and ensure your oven reaches the proper temperature before baking. You can also leave them in the oven slightly longer.
