18-hour bone broth: A chef’s guide to collagen-rich soup for glowing skin

The aroma of simmering bones and aromatic vegetables fills my kitchen, transporting me back to my childhood in New Orleans. My French father, a chef, would spend hours crafting the perfect bone broth, a culinary tradition passed down through generations. Today, I’m excited to share with you my recipe for a Collagen-Rich Bone Broth Soup that not only nourishes your body but also supports skin elasticity. This liquid gold, as we called it in culinary school, is a testament to the power of slow cooking and the magic that happens when humble ingredients are transformed through time and technique.

The Story Behind Collagen-Rich Bone Broth Soup

Bone broth has been a staple in cuisines around the world for centuries, prized for its rich flavor and numerous health benefits. In France, it’s the foundation of many classic dishes, while in America, it’s experiencing a renaissance as a superfood. The key to its skin-supporting properties lies in the collagen extracted from the bones during the long cooking process. As a chef who’s bridged the gap between French technique and American practicality, I’ve perfected a method that maximizes collagen extraction while keeping the process approachable for home cooks.

Dr. Sarah Johnson, a nutritionist specializing in skin health, explains, “Collagen is the most abundant protein in our bodies, crucial for maintaining skin elasticity. As we age, our natural collagen production decreases, making dietary sources increasingly important.” This soup isn’t just delicious; it’s a beauty treatment in a bowl.

Essential Ingredients Guide

The magic of this broth lies in its simplicity. Here’s what you’ll need:

  • 2 kg beef marrow bones
  • 1 kg chicken feet (for extra collagen)
  • 3 parsnips, roughly chopped
  • 4 carrots, roughly chopped
  • 1/2 celery head, roughly chopped
  • 1 leek, cleaned and chopped
  • 2 bay leaves
  • 4 sprigs of fresh thyme
  • 2 tablespoons apple cider vinegar
  • Salt and pepper to taste
  • 3 liters of water

Pro Tip: Don’t skip the chicken feet! They’re a collagen powerhouse. If you’re squeamish, just close your eyes and think of the beauty benefits.

Kitchen Equipment Checklist

Before we dive in, make sure you have:

  • A large stockpot or Dutch oven (at least 8-quart capacity)
  • A fine-mesh strainer
  • Cheesecloth (for ultra-clear broth)
  • Large bowls for straining
  • Storage containers or mason jars

If you don’t have a large stockpot, don’t worry. You can make this recipe in a slow cooker or Instant Pot with some adjustments to the cooking time.

Step-by-Step Instructions

1. Preheat your oven to 180°C (350°F). Spread the beef bones on a baking sheet and roast for 30 minutes to enhance flavor.

2. While the bones are roasting, clean and chop your vegetables.

3. In your large stockpot, combine the roasted beef bones, chicken feet, and all vegetables.

4. Add the bay leaves, thyme, and apple cider vinegar. The acid helps extract more collagen from the bones.

5. Pour in 3 liters of cold water, ensuring all ingredients are covered.

6. Bring the mixture to a boil over high heat, then reduce to the lowest setting for a gentle simmer.

7. Simmer uncovered for 12-24 hours. The longer you simmer, the more collagen you’ll extract. I aim for at least 18 hours for optimal results.

8. Throughout the cooking process, skim off any foam or impurities that rise to the surface.

9. In the last hour of cooking, season with salt and pepper to taste.

10. Once done, remove from heat and let cool slightly.

11. Strain the broth through a fine-mesh strainer lined with cheesecloth into large bowls.

12. Let the broth cool to room temperature before transferring to storage containers.

Chef’s Secret Techniques

The key to a superior bone broth lies in the details:

1. Roasting the bones beforehand adds depth of flavor. In French cuisine, we call this process “caramelization,” and it’s essential for developing a rich taste profile.

2. Don’t be tempted to stir the broth too often. Let it simmer undisturbed to maintain clarity.

3. For an extra boost of flavor, try adding a handful of dried mushrooms in the last few hours of cooking. They’ll impart a wonderful umami depth to your broth.

4. If you’re short on time, you can use an Instant Pot to speed up the process. Cook on high pressure for 3 hours, then let it naturally release for 30 minutes.

Common Pitfalls and Solutions

Even experienced chefs can encounter challenges. Here’s how to troubleshoot common issues:

1. Cloudy broth: This is often caused by boiling instead of simmering. Keep your heat low and steady.

2. Lack of gelatin: If your broth doesn’t gel when cooled, you may not have used enough collagen-rich bones. Next time, increase the ratio of joint bones and add more chicken feet.

3. Greasy broth: Allow the broth to cool completely in the refrigerator. The fat will solidify on top, making it easy to remove.

Serving & Presentation Tips

While this broth is delicious on its own, here are some ways to elevate it:

1. Serve in warmed bowls with a sprinkle of fresh herbs like parsley or chives.

2. Add a splash of sherry or cognac for a French twist.

3. Use it as a base for other soups, like my Lemon Chicken Breast Soup, which is both easy and delicious.

4. Drizzle with a high-quality extra virgin olive oil for added richness.

Recipe Variations & Adaptations

This versatile broth can be customized to suit various dietary needs and preferences:

1. For a lighter version, use only chicken bones and feet.

2. Add immune-boosting ingredients like ginger, turmeric, and garlic in the last hour of cooking.

3. For a richer flavor, try using a mix of beef, pork, and chicken bones.

4. Vegetarian alternative: While not a true bone broth, a mineral-rich vegetable stock can be made using mushrooms, seaweed, and mineral-dense vegetables.

Wine Pairing & Serving Suggestions

While bone broth is often enjoyed on its own, it pairs beautifully with light, crisp wines that complement its richness without overpowering it. Consider a Chablis or a light Pinot Noir.

For a complete meal, serve your bone broth alongside:

1. A crusty baguette for dipping

2. A simple green salad with a light vinaigrette

3. For a heartier option, try my Creamy Lemon Chicken Fettuccine as a main course

Storage & Reheating Guide

To preserve your liquid gold:

1. Refrigerate cooled broth in airtight containers for up to 5 days.

2. Freeze in portions for up to 6 months. I recommend using silicone molds for easy portioning.

3. To reheat, gently warm on the stovetop. Never microwave, as this can degrade the collagen.

Remember, a good bone broth is more than just a recipe; it’s a ritual of nourishment and care. As we say in French kitchens, “La patience est la vertu des grands cuisiniers” – patience is the virtue of great cooks. So take your time, enjoy the process, and nourish your body and soul with this collagen-rich elixir. Bon appétit!
