Before you start
Before starting, ensure your slow cooker is clean and positioned on a stable, heat-resistant surface. Wash and slice your carrots into uniform rounds to ensure they cook at the same rate as the lentils. If your beef shank has excessive fat, you may choose to trim it, though a little fat helps keep the meat moist during the long cooking time.
Have your measuring cups ready and ensure you have enough water to fully submerge the ingredients according to the recipe instructions. Proper preparation of the ingredients ensures a seamless assembly process.

Instructions
Assembly of ingredients
- Prepare the slow cookerPlace the beef shank chunks into the bottom of the slow cooker to ensure even heat distribution and contact with the heat source.Look for Beef is arranged in a single layer at the base.Tip Ensure the beef chunks are relatively uniform in size for consistent cooking.
- Add vegetables and aromaticsDistribute the sliced carrots and blond lentils over the beef. Crumble the dry bouillon cube evenly over the top of the ingredients.Look for Vegetables and lentils are scattered across the beef.Tip Crumbling the bouillon cube ensures it dissolves quickly as the liquid heats up.
At the end of this phase, the slow cooker should be neatly layered with the beef at the bottom, followed by the carrots and lentils, and topped with the crumbled bouillon. Everything should be ready for the addition of water. Ensure the beef is evenly spaced to prevent clumps. This stage is critical for establishing the foundation of the dish, as correct placement ensures that the ingredients interact properly as the temperature rises, setting the stage for a perfectly cooked, flavorful final result.
Slow cooking process
- Add liquid and cookPour the water over the contents in the slow cooker. Cover and cook on low for 8 hours until the beef reaches 145°F (63°C). Once cooked, let the meat rest for at least 3 minutes.Look for Liquid covers the ingredients completely.Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)Tip Check the water level halfway through if your cooker tends to lose moisture.
During the cooking phase, the slow cooker will begin to release a savory aroma as the beef and bouillon meld together. By the end of this period, the liquid should be simmering gently, and the beef should look significantly darker and more tender. The lentils will have absorbed a portion of the broth, swelling in size. The house should smell rich and savory. Check that the water level has remained consistent, ensuring the ingredients stay submerged for even cooking throughout the entire duration.
Final resting and serving
- Finish and serveOnce the meat has rested, ensure the beef is tender and the lentils are cooked through. Serve the dish warm on a plate, ensuring each serving includes a portion of the meat, lentils, and carrots.Look for Beef is tender and pulls apart easily with a fork.Tip Resting the meat is essential for maintaining juiciness before serving on a plate.
Once the cooking is complete, the meat should be exceptionally tender, and the lentils should be fully cooked, soft, and flavorful. The sauce should be glossy and rich. After the required resting period, the beef should be easy to slice or shred.
Check that the vegetables are cooked through and that the overall dish has reached a uniform, appetizing consistency. The final result should be a cohesive, warm, and comforting meal ready to be plated and served immediately to ensure the best temperature and texture.
Common mistakes
A common mistake is overcrowding the slow cooker, which can prevent even heat distribution and result in unevenly cooked meat. Ensure there is enough space for the liquid to circulate properly. Another error is using lentils that are too delicate, such as red lentils, which will turn to mush during the long cooking time.
Finally, do not lift the lid too frequently during the cooking process, as this releases heat and moisture, significantly extending the cooking time and potentially affecting the final texture of the beef and vegetables.
How to tell it’s done
The beef is done when it is fork-tender and pulls apart easily with minimal resistance. To ensure food safety, verify that the thickest part of the meat has reached an internal temperature of at least 145°F (63°C).
The lentils should be soft but not completely disintegrated, and the carrots should be tender when pierced with a fork. Always allow the meat to rest for at least 3 minutes after removing it from the slow cooker to allow the internal juices to redistribute, ensuring the best possible texture.
- Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
