Zero-carb slow roasted butter beef with bone marrow, egg yolk reduction, crispy beef fat, smoked salt finish, and pan roasted liver
Ingredients
5 kilograms beef chuck roast with heavy marbling
2 kilograms beef short ribs
1 kilogram beef marrow bones
1 kilogram beef fat trimmings or suet
500 grams beef liver
12 egg yolks
500 grams unsalted butter
250 grams beef tallow
3 tablespoons sea salt
2 tablespoons smoked salt
2 tablespoons black pepper optional because some strict zero-carb eaters avoid spices
2 liters water
1 tablespoon apple cider vinegar optional for marrow extraction though technically not fully zero-carb
Extra beef drippings reserved during cooking
Preparation of the beef
Remove the beef chuck roast and short ribs from refrigeration and allow them to sit at room temperature for approximately one hour. Pat every surface completely dry using paper towels because moisture prevents proper browning and crust formation. Trim only excessively hard external fat while leaving most fat intact because rendered fat is a major component of the final texture and flavor.
Preparation of marrow bones
Place marrow bones into cold salted water for thirty minutes to draw out blood residue. Drain thoroughly and dry completely. Arrange them on a tray and lightly coat with melted tallow.
Preparation of rendered beef fat
Cut the beef fat trimmings into very small cubes. Place them into a very large heavy pot over extremely low heat. Allow the fat to slowly melt for one to two hours while stirring occasionally. The rendered liquid fat becomes clear tallow while the remaining browned pieces become crispy beef cracklings. Remove the cracklings once deeply golden and reserve them separately. Strain the rendered tallow through a fine mesh filter and keep warm.
Initial roasting stage
Preheat oven to 120 degrees Celsius. Heat a massive cast iron roasting vessel until extremely hot. Add several tablespoons of rendered tallow. Carefully place the beef chuck roast into the vessel and sear every surface until deeply dark brown. Repeat with short ribs. Browning should occur slowly and thoroughly because this creates the deepest flavor foundation.
Transfer the browned meat into the roasting vessel. Arrange marrow bones around the meat. Pour in two liters of water around the edges without washing away the browned crust. Cover tightly with a heavy lid.
Slow roasting process
Roast for approximately eight to ten hours. Every hour open the lid briefly and baste all surfaces using rendered fat and collected juices. During roasting collagen gradually melts into gelatin while fat renders through the meat fibers creating an almost buttery texture.
After five hours the marrow bones should become soft internally. Remove them carefully and scoop the marrow into a bowl. Mix the marrow with melted butter and a small quantity of smoked salt until smooth and glossy.
Preparation of liver
Slice liver into thick strips. Heat a separate cast iron pan until smoking hot. Add rendered tallow. Place liver strips into the pan without overcrowding. Cook for roughly forty five seconds per side to maintain a soft center. Overcooking liver causes dryness and metallic bitterness. Rest the liver in warm butter.
Egg yolk reduction sauce
Place egg yolks into a metal bowl over barely simmering water. Slowly whisk in warm beef drippings and melted butter continuously. Continue whisking until the sauce thickens into a glossy rich emulsion similar to hollandaise but entirely meat based. Add marrow mixture gradually while whisking. The final sauce should be thick enough to coat the back of a spoon while remaining pourable.
Final high heat finishing stage
Increase oven temperature to 260 degrees Celsius. Uncover the beef and baste heavily with rendered fat. Roast uncovered for fifteen to twenty minutes until edges become dark and slightly crisp. The exposed fat should bubble aggressively while the crust deepens into a near black bark.
Resting period
Remove meat from oven and allow it to rest for at least forty minutes. During resting the internal juices redistribute through muscle fibers instead of escaping immediately during slicing.
Assembly
Place enormous sections of beef onto a serving board. Spoon marrow egg yolk reduction over the top. Scatter crispy beef cracklings across the surface. Arrange roasted marrow bones beside the meat so marrow can be spread directly onto slices. Add strips of liver around the edges. Drizzle additional hot tallow over everything immediately before serving.
Texture and flavor profile
The beef should collapse under minimal pressure while remaining juicy. The marrow sauce creates a dense velvety richness coating every bite. Crispy rendered fat contrasts with the soft interior meat. Liver introduces an intense mineral depth balancing the buttery fat.
Serving suggestions for strict zero-carb eating
Serve alone without vegetables or sauces. Additional melted butter or warm tallow may be poured over individual servings for higher fat intake. Bone broth made from the remaining roasting liquid can accompany the meal.
Storage and reheating
Store leftover meat submerged in its own fat and juices to preserve moisture. Refrigerate for up to five days. Reheat slowly in covered cookware with additional tallow to prevent drying. The flavor often becomes even deeper after resting overnight because gelatin and fat continue integrating into the meat fibers.
Extended optional preparation for extreme richness
For an even more concentrated result the entire roast may be chilled overnight after initial cooking. The next day remove hardened fat from the surface and reserve separately. Slice the cold meat into enormous slabs and sear them again in hot tallow until a secondary crust develops. Reduce the remaining cooking liquid until thick like glaze and pour over the re-seared meat. This double cooking method creates extraordinary density of flavor with an almost steakhouse style exterior surrounding extremely soft interior meat.
