Roasted Bone Marrow With Caramelized White Turnip

The first time I had bone marrow was a revelation. It was at a tiny bistro in Lyon, France, and the dish arrived looking almost medieval – these hefty bones, split open to reveal their glistening treasure within. I remember the savory, almost sweet aroma filling the air, and the utter richness of that first bite. It was an experience that transformed my understanding of flavor, and ever since, I’ve been experimenting with ways to showcase this incredible ingredient. This recipe, featuring caramelized white turnips, is a tribute to that initial culinary awakening – a perfect blend of rustic charm and refined taste.

• Total Time: 1 hour 15 minutes
• Servings: 2
• Dietary Type: High Fat

Ingredients

• 6-8 beef bones with marrow, about 3 inches long (or 1-2 lbs beef bones with marrow)
• 1 leek
• 2 carrots
• 1 garlic clove
• 2 bay leaves
• 2-3 turnips (or 2-3 swedes)
• Sugar
• Butter
• Parsley
• Crusty salt
• Maldon sea salt or fleur de sel de Guérande

Equipment Needed

• Large pot
• Oven
• Large pan
• Cutting board
• Chef’s knife

Instructions

1. Begin by preparing the beef bones. Place the beef bones with marrow, along with the chopped leek and carrots, garlic, and bay leaves, into a large pot.
2. Add enough water to completely cover the bones and vegetables. Bring the pot to a boil over high heat.
3. As the water heats, any impurities will rise to the surface. Use a spoon to skim any foam that forms from the water’s surface. This step helps to create a clearer and cleaner-tasting broth.
4. Once the pot is boiling, reduce the heat to a simmer and let it cook for about 30 minutes. This gently poaches the marrow and infuses it with the flavors of the vegetables and herbs.
5. After 30 minutes of simmering, carefully remove the beef bones from the stock. Place them on a baking sheet lined with parchment paper for easier cleanup.
6. Preheat your oven to approximately 350°F (175°C).
7. Place the baking sheet with the beef bones into the preheated oven and roast for 10-15 minutes. The goal is to cook the marrow until it is soft and has just begun to separate from the bone. Watch carefully to prevent the marrow from melting completely and drizzling out.
8. While the bones are roasting, prepare the turnips. Peel the turnips and cut them into thin slices. Aim for a uniform thickness to ensure even cooking.
9. Place a generous amount of butter in a large pan over medium heat. Make sure the pan is large enough to accommodate all the turnip slices in a single layer.
10. Add the turnip slices to the pan, arranging them so that each slice touches the bottom. This maximizes contact with the hot butter and promotes even caramelization.
11. Fry the turnip slices until they are golden brown on one side. Flip the slices and continue to cook until both sides are caramelized and tender.
12. Once the turnips are nicely browned, sprinkle 2 pinches of sugar and a pinch of salt over them. The sugar will caramelize quickly, so watch carefully to prevent burning. Stir gently to coat the turnips evenly with the caramelized sugar.
13. While the turnips caramelize, finely chop a handful of fresh parsley.
14. Remove the beef bones from the oven.
15. To serve, arrange 3-4 marrow bones on each plate. Spoon the caramelized turnips beside the bones. Sprinkle the chopped parsley generously over the dish.
16. Season with crusty salt and freshly ground black pepper to taste.
17. Serve immediately with 2 slices of toast on the side for spreading the roasted marrow.

Expert Tips & Tricks

• Bone Selection: When selecting beef bones, look for bones that are approximately 3 inches long and have a good amount of marrow. The femur bones are a good choice.
• Soaking the Bones: For a richer flavor, soak the bones in cold, salted water for 12-24 hours before cooking. This helps to draw out any impurities.
• Flavor Infusion: Enhance the stock by adding other vegetables like celery, parsnip or herbs like thyme and rosemary.
• Caramelization Control: Keep a close eye on the turnips while they are caramelizing, as the sugar can burn quickly. Adjust the heat as needed to prevent burning and achieve a deep golden-brown color.
• Marrow Doneness: To test if the marrow is done, insert a thin knife or skewer into the center. If it goes in easily with little resistance, the marrow is ready.
• Toast Preparation: Toast the bread slices just before serving to ensure they are warm and crispy.

Serving & Storage Suggestions

Serve the roasted bone marrow and caramelized turnips immediately while they are hot and fresh. The marrow is best enjoyed spread on warm toast. Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. To reheat, place the bone marrow in a preheated oven at 300°F (150°C) until warmed through. Reheat the turnips separately in a pan over medium heat until heated through. Room temperature is not recommended for longer than 2 hours. Freezing is not recommended.
