Step-by-Step Making Process

Step 1: Preparing the Ingredients

Before you start cooking, it’s important to prepare everything in advance.

1. Rinse the lentils under cold water and drain them.
2. Chop the vegetables into small, even-sized pieces for even cooking.
3. Measure out the spices so you can easily add them while cooking.

💡 Tip: Using pre-chopped vegetables can save time if you’re in a hurry.

Step 2: Sautéing for Maximum Flavor

Sautéing your base ingredients enhances the depth of flavor in the soup.

1. Heat olive oil in a large pot over medium heat.
2. Add onions, carrots, and celery, and cook for about 5 minutes until softened.
3. Stir in garlic, oregano, thyme, and red pepper flakes. Cook for another 30 seconds until fragrant.

💡 Tip: Avoid burning the garlic, as it can make the soup taste bitter.

Step 3: Cooking the Lentils & Vegetables

1. Pour in the diced tomatoes, vegetable broth, and water.
2. Add the lentils, stir well, and bring to a gentle simmer.
3. Reduce heat to low and cover the pot. Let it cook for 25-30 minutes, stirring occasionally.
4. After 20 minutes, add the zucchini and season with salt and black pepper.

💡 Tip: If the soup gets too thick, add a little extra broth or water.

Step 4: Finishing with Parmesan & Garnishes

1. Once the lentils are tender, remove the pot from heat.
2. Stir in grated Parmesan cheese until it melts into the soup.
3. Garnish with fresh parsley and a squeeze of lemon juice for brightness.
4. Serve hot with crusty bread or a side salad.

💡 Tip: Adding a little more Parmesan on top makes the soup extra flavorful.
