The Key Ingredients for This Recipe

A spectacular soup starts with quality components. For this recipe for soup using leeks and beef, selecting the right ingredients is key to the final result.

The Best Beef for Soup

The foundation of our soup is beef. For the best flavor and texture, beef chuck roast is the undisputed champion. It has fantastic marbling and connective tissue that breaks down during the long, slow cook, yielding succulent beef and adding incredible body to the broth. When making a recipe for soup using leeks and beef, avoiding pre-cut “stew meat” is a pro-tip, as it can contain mixed cuts that cook unevenly.

• Alternatives:
  • Brisket: Offers a similar fat content and becomes incredibly tender.
  • Boneless Short Ribs: A more luxurious option for an exceptionally rich leek and beef soup.

The Star of the Show: Leeks

Leeks provide a sweet, mild onion flavor that is more delicate than their pungent cousins. Their gentle character is what elevates this from a simple beef soup to a sophisticated leek and beef soup.

How to Properly Clean Leeks

Leeks are notorious for trapping grit. A sandy soup is a ruined soup, so this step is non-negotiable.

1. Trim: Slice off the dark green tops and the root end.
2. Slice: Cut the remaining white and light-green part in half lengthwise.
3. Rinse: Hold each half under cold running water, fanning the layers to flush out any hidden sand.
4. Chop: Slice the clean halves into half-moon shapes for your soup.

Broth & Aromatics

• Beef Broth: Use a good quality, low-sodium beef broth.
• Onion & Garlic: The aromatic base of our recipe for soup using leeks and beef.
• Carrots & Celery: For sweetness and depth.
• Thyme: Adds a complementary earthy note.
• Tomato Paste: For a touch of umami and richness.

Step-by-Step Instructions

1. Prepare the Beef: Pat your beef cubes completely dry and season generously with salt and pepper. This is a critical first step for this recipe for soup using leeks and beef.
2. Sear the Beef: In a large Dutch oven, heat oil over medium-high heat. Working in batches, sear the beef cubes until deeply browned on all sides. Do not crowd the pan!
3. Sauté the Aromatics: Reduce heat to medium. Sauté the onions, carrots, and celery for 5-7 minutes. Add the garlic and tomato paste and cook for another minute.
4. Deglaze the Pot: Pour in a splash of beef broth and scrape up all the browned bits (the “fond”). This is pure flavor for your leek beef soup.
5. Simmer the Soup: Return the beef to the pot. Add the cleaned leeks, the remaining beef broth, and thyme. Bring to a boil, then reduce heat to low, cover, and simmer for at least 2 to 2.5 hours.
6. Finish and Serve: Remove thyme stems. Adjust seasoning with salt and pepper. Serve this delicious leek and beef soup hot.

Expert Tips for a Perfect Soup
