Ingredients:
- 3 lbs beef chuck roast, trimmed and cut into large chunks
- 1/4 cup extra virgin olive oil
- 4 tbsp lemon juice, freshly squeezed
- 2 tbsp red wine vinegar
- 6 cloves garlic, minced into a paste
- 2 tbsp dried Greek oregano
- 1 tbsp dried thyme
- 1 tsp cumin
- 1.5 tsp sea salt
- 1 tsp cracked black pepper
- 2 cups full-fat Greek yogurt (10% fat)
- 1 large English cucumber, grated and squeezed dry
- 2 tbsp fresh dill, finely chopped
- 1 tbsp lemon juice (for tzatziki)
- 1 clove garlic, grated (for tzatziki)
- 6 soft pita breads
- 1 medium red onion, thinly sliced
- 2 English tomatoes, sliced into wedges
Instructions:
- In a medium bowl, whisk together the extra virgin olive oil, 4 tbsp lemon juice, red wine vinegar, 6 minced garlic cloves, oregano, thyme, cumin, sea salt, and black pepper to create the marinade.
- Place the beef chuck roast chunks into a 6-quart slow cooker and pour the marinade base over the meat, tossing to ensure all surfaces are thoroughly coated.
- Cover and cook on LOW for 7–8 hours (or HIGH for 4 hours) until the connective tissue has converted to gelatin and the meat is tender.
- While the meat cooks, prepare the tzatziki by combining the Greek yogurt, grated and drained cucumber, fresh dill, 1 tbsp lemon juice, and 1 grated garlic clove. Refrigerate until serving.
- Remove the beef from the slow cooker and shred with forks. Heat a cast-iron skillet over medium-high heat and flash-sear the shredded beef in batches to create crispy, mahogany-colored edges.
- Lightly char the pita breads. Assemble the gyros by layering the seared beef, tzatziki sauce, sliced red onions, and tomato wedges inside the pitas.
