Ingredients
  

The Base
  • 1/4 Cup Extra virgin olive oil
  • 3/4 Cup yellow onion (finely diced)
  • 1/3 Cup yellow onion (grated)
  • 3/4 Cup carrots (diced)
  • 3/4 Cup celery (diced)
  • 1 1/2 Tbsp garlic (finely minced)
  • 1/3 Cup Dry red wine
The Soup & Body
  • 1 (15 oz) can Brown lentils, rinsed and drained
  • 1 (10 oz) can diced tomatoes
  • 4 1/2 Cups Water
  • 1 3/4 Tbsp Better Than Bouillon Beef Base
  • 1/4 Cup Ditalini pasta
  • 1 tsp Fennel seeds (coarse-ground)
  • 1/2 tsp Dried oregano
  • 2 tsp Dried parsley
  • 1 Large bay leaf
  • 1/8 tsp cracked black pepper
  • 1 tsp Fresh Lemon Juice (or 1/2 tsp from concentrate)

Equipment

  • 1 Wooden Cooking Spoon
  • 1 Chef’s Knife & Cutting Board

Instructions
 

  1. The Flash Sauté: Heat the extra virgin olive oil in your saucepan over medium-high heat. Add the finely diced onion, grated onion, carrots, and celery. Sauté for 5–7 minutes, stirring frequently, until the vegetables are soft, highly aromatic, and translucent.

  2. The Garlic Bloom & Red Wine Deglaze: Clear a small circle in the center of your vegetables. Drop in the minced garlic and cook for 60 seconds until fragrant. Immediately pour in your ⅓ cup of dry red wine. Use your wooden spoon to aggressively scrape up any caramelized vegetable bits (the fond) stuck to the bottom of the pot while the wine bubbles down for 1 to 2 minutes.
  3. The Spice & Tomato Dump: Pour in the 10 oz can of diced tomatoes with all their juices, the 4 ½ cups of water, and stir in the 1 ¾ tablespoons of beef bouillon until completely dissolved. Add the rinsed canned lentils, coarse-ground fennel seeds, oregano, parsley, the bay leaf, and your ⅛ teaspoon of black pepper. Bring the entire pot up to a steady, roaring boil.
  4. The Pasta Finish: Drop the ¼ cup of Ditalini pasta directly into the boiling soup. Leave the pot completely uncovered, lower the heat slightly to a steady medium simmer, and cook for 8–10 minutes until the Ditalini is perfectly al dente.
  5. The Final Audit & Lemon Pop: Turn off the heat and fish out the bay leaf. Stir exactly 1 teaspoon of fresh lemon juice completely through the warm broth to brighten the flavors and perfectly balance the tomato heat. Let the pot sit and rest uncovered for 3–5 minutes to settle and tighten up before serving.

Plating and Serving
  1. The Oil Drizzle: A final swirl of high-quality Extra Virgin Olive Oil on top adds a silky "mouthfeel" and brings out the earthiness of the lentils.
  2. The Cheese: Offer a generous dusting of grated Parmesan or Pecorino Romano cheese at the table. The salt and sharp tang melt beautifully into the broth, perfectly balancing the rich beef base.

Notes

The “Hot” Tomato Variation

Note on Adding Heat: If you love a spicy kick, you can substitute the standard 10 oz can of plain diced tomatoes with 1 (10 oz) can of Hot Diced Tomatoes with Green Chilies. Because the “hot” style canned tomatoes already introduce a significant amount of built-in spice, keep the added black pepper strictly at 1/8 teaspoon during the simmer to prevent the heat from overpowering the soup.
The Onion “Hack”: Using both diced and grated onions is our signature technique. The finely diced onions provide classic texture, while the grated onion breaks down instantly in the boiling broth, adding an immediate body and thickness that usually requires hours of slow simmering.
