Ingredients
- 1 tablespoon olive oil or vegetable oil
- 1 large yellow onion, diced
- 3 medium carrots, sliced into rounds
- 3 stalks celery, chopped
- 4 cloves garlic, minced
- 1 pound dried brown or green lentils, rinsed
- 1 can (28 oz) crushed tomatoes
- 8 cups water mixed with bouillon or vegetable broth
- 2 teaspoons dried Italian seasoning
- 1 teaspoon smoked paprika
- 2 cups fresh spinach or kale, roughly chopped
- Salt and black pepper to taste
- Optional: Lemon juice for brightness
Directions
Step 1: Sauté the Aromatics
Heat the oil in a large stockpot over medium heat. Add the diced onion, carrots, and celery. Sauté the vegetables for about 6 to 8 minutes until the onions become translucent and the carrots soften slightly. Stir in the minced garlic and cook for another 60 seconds until fragrant, being careful not to let the garlic burn.
Step 2: Simmer the Soup
Add the rinsed lentils, crushed tomatoes, Italian seasoning, and smoked paprika to the pot. Pour in the broth or water. Stir everything well to combine. Bring the mixture to a rolling boil, then immediately reduce the heat to low. Cover the pot with a lid and simmer for 25 to 30 minutes, or until the lentils are tender but not mushy.
Step 3: Finish and Season
Once the lentils are cooked, stir in the chopped spinach or kale. The residual heat will wilt the greens in about 2 minutes. Taste the soup and add salt and pepper as needed. For an extra punch of flavor, squeeze in a little fresh lemon juice right before serving. Ladle the soup into bowls and enjoy immediately, or portion it out into containers for your weekly meal prep.
Expert Tips for Perfect Budget Meal Prep Soup Under $20 Cheap Easy Family $5 Dinners
To maximize your savings, buy your lentils and spices in the bulk section of the grocery store. If you want a creamier texture without adding dairy, take two cups of the finished soup, blend it in a blender, and stir it back into the pot. Always rinse your lentils under cold water before cooking to remove any dust or small debris. If the soup becomes too thick after sitting in the fridge, simply add a splash of water or broth when reheating to bring it back to your desired consistency.
Delicious Variations
- Meat Lover’s Version: Brown some affordable ground turkey or sliced smoked sausage with the onions for added protein.
- Spicy Kick: Add a half teaspoon of red pepper flakes or a diced jalapeño to the sauté step.
- Root Vegetable Swap: Use diced potatoes or sweet potatoes instead of lentils if you prefer a starchier base.
- Mexican Style: Swap the Italian seasoning for cumin and chili powder, and use black beans instead of lentils.
