How to Make High-Protein Slow Cooker Beef
1. Prepare the beef
Cut the chuck roast or boneless short ribs into approximately 2-inch chunks. Avoid placing one huge piece of beef into the slow cooker because smaller pieces allow the meat to cook more evenly.
Add the beef to your slow cooker.
2. Add the seasonings
Add the sliced onion, minced garlic, freshly grated ginger, soy sauce or tamari, bone broth, rice vinegar, honey or sugar-free honey, sesame oil, and chili flakes.
Stir or gently toss everything together.
3. Slow cook
Cover with the lid and cook on LOW for approximately 8 hours, or until the beef is very tender and easily pulls apart with a fork.
4. Shred the beef
Once cooked, shred the beef directly in the slow cooker using two forks. Mix it with some of the flavorful cooking liquid.
5. Roast the sweet potato
Preheat your oven to 350°F (175°C).
Place the sweet potato in the oven and roast for approximately 75 minutes, or until tender when pierced with a fork.
You can also substitute regular potatoes, quinoa, rice, or a low-carb rice alternative.
6. Make the cucumber salad
Thinly slice the Persian cucumbers.
Add the lime juice, rice vinegar, salt, and Korean chili flakes or Aleppo pepper. Toss everything together and set aside.
7. Make the chili-lime sauce
In a small bowl, combine mayonnaise, lime juice, sriracha, rice vinegar, and a pinch of salt.
Mix until smooth and creamy.
8. Assemble
Cut open the roasted sweet potato and mash part of the inside with a fork.
Top with shredded slow cooker beef and cucumber salad. Drizzle with the chili-lime sauce and serve immediately.
Serving Suggestions

High-Protein Meal Prep
This slow cooker beef is an excellent option when you want to prepare several meals at once. Make a large batch on the weekend and use the shredded beef throughout the week in different combinations.
Try one serving with sweet potato and cucumber salad, another over rice and vegetables, or use the beef in a high-protein bowl with cauliflower rice and fresh vegetables.
The same slow-cooked beef can taste completely different depending on the sides and toppings you choose.
Recipe Tips
Cut the beef into chunks: Smaller pieces help the beef cook evenly and become tender.
Don't skip the ginger and garlic: They add a lot of flavor to the cooking liquid.
Adjust the spice: Add more or less chili flakes and sriracha depending on your preferred heat level.
Make it lower-carb: Serve the beef with cauliflower rice or another low-carb rice alternative and use sugar-free honey if desired.
Store leftovers properly: Refrigerate cooked beef promptly in an airtight container and use within a few days, or freeze portions for longer storage.
