Ingredients You’ll Need

There’s nothing complicated here—each ingredient is thoughtfully chosen for maximum flavor and authentic gyro texture. The steak becomes impossibly tender in the slow cooker, while bright veggies and homemade tzatziki bring layers of color, crunch, and tangy freshness to every bite.

• Low-sodium beef broth: Adds deep, savory flavor and moisture to keep the steak succulent as it cooks low and slow.
• Sirloin steak: Choose a lean, well-marbled cut—cutting into thin strips lets everything soak up those Mediterranean flavors.
• Onion: Sliced onion melts down beautifully as it cooks, infusing the steak with sweetness and depth.
• Olive oil: Classic Greek flavor that helps infuse and tenderize the meat.
• Garlic: Fresh minced garlic is essential for that punchy, aromatic base every good gyro deserves.
• Dried oregano: This signature herb delivers that “just like a Greek taverna” aroma as soon as you lift the lid.
• Salt and black pepper: Simple but crucial for balancing and highlighting all the other flavors.
• Lemon juice: A touch of acidity brightens everything up and tenderizes the steak as it cooks.
• Pita bread: Soft, pillowy pitas are the perfect handheld vessel for every juicy, saucy bite.
• Shredded lettuce: Brings a fresh, crisp bite, and is a gyro must-have.
• Tomatoes and cucumber: Vibrant, juicy veggies add both sweetness and crunch.
• Whole milk Greek yogurt: The rich, creamy base for homemade tzatziki—it’s worth using the full-fat kind!
• English cucumber: Its mild flavor and low seeds make it perfect for tzatziki—you’ll love how cooling it is.
• Red wine vinegar: Adds authentic zing and depth to the tzatziki sauce.
• Extra garlic, lemon juice, salt and pepper: Build irresistible layers of flavor in the sauce.

Variations

The beauty of Tender Slow Cooker Steak Gyros is how easy they are to adapt—whether you’re swapping for dietary needs, adjusting heat, or simply working with what’s already in your fridge. Here are some fun ways to switch things up:

• Chicken Gyros: Substitute boneless, skinless chicken thighs for steak for a lighter take, adjusting cooking time to 4-5 hours on low.
• Low-Carb Option: Serve the melt-in-your-mouth steak and veggies over a big Greek salad bowl and skip the pita entirely.
• Spicy Kick: Add a pinch of crushed red pepper flakes or swap in a little harissa to your slow cooker for a fiery twist.
• Dairy-Free Tzatziki: Use your favorite plant-based Greek-style yogurt for a sauce that’s just as refreshing.

How to Make Tender Slow Cooker Steak Gyros

Step 1: Build the Flavor Base

Start by pouring the beef broth into the bottom of your slow cooker. This creates a steamy, savory bath for the steak and ensures the meat will stay juicy and ultra-tender during those long, slow hours.

Step 2: Layer the Steak and Onions

Add your sliced sirloin steak on top of the broth, followed by a blanket of thinly sliced onions. The onions will soften beautifully and “melt” into the meat, infusing each bite with a hint of sweetness.

Step 3: Mix Up the Seasoning

In a small bowl, whisk together the olive oil, minced garlic, oregano, salt, pepper, and lemon juice. Drizzle this punchy marinade evenly over your steak and onions—every drop brings layers of Mediterranean sunshine to the final dish.

Step 4: Slow Cook to Perfection

Pop the lid on, set your slow cooker to low, and let time work its magic. In 7-8 hours, you’ll open the lid to find steak that’s deeply flavorful, fork-tender, and practically falling apart—just right for gyros!

Step 5: Whip Up the Homemade Tzatziki

While your steak finishes, stir together Greek yogurt, diced cucumber, minced garlic, red wine vinegar, lemon juice, salt, and pepper in a bowl. Pop this in the fridge for at least 30 minutes—the flavors meld and become so refreshing and tangy.

Step 6: Assemble Your Gyros

Warm your pita breads, then generously layer on that slow cooked steak, crisp lettuce, juicy tomatoes, cucumber slices, and a generous drizzle of homemade tzatziki. Each bite is a total flavor bomb!

How to Serve Tender Slow Cooker Steak Gyros

Garnishes

For that restaurant-style finish, sprinkle your Tender Slow Cooker Steak Gyros with a dusting of fresh chopped parsley or dill, a handful of crumbly feta, or a pinch more black pepper. A little squeeze of lemon over the top just before serving makes the flavors pop with brightness!

Side Dishes

These gyros are dreamy with a simple side of crispy oven potatoes, lemony rice pilaf, or even a Greek village salad with olives and feta. If you’re feeling snacky, a bowl of hummus with warm pita chips is always a table hit.

Creative Ways to Present

Try serving everything family-style: lay out a build-your-own gyro bar with warm pitas, all the veggies, juicy steak, and a big bowl of homemade tzatziki so everyone can load up to their heart’s content. For parties, stuff the filling into mini pitas or even serve as lettuce wraps for a lighter, bite-sized treat!

Make Ahead and Storage

Storing Leftovers

Any leftover steak and sauce can be stored in airtight containers in the fridge for 3-4 days. Keep toppings and pitas separate until you’re ready to assemble so everything stays fresh and vibrant.

Freezing

The cooked steak freezes wonderfully—in fact, it’s a meal-prepper’s dream! Let it cool, then portion into freezer bags or containers. Thaw overnight in the fridge, and reheat gently for gyros in a flash. (Skip freezing veggies and tzatziki, though—they’re best fresh.)

Reheating

To reheat, pop the steak in a covered skillet over low heat with a splash of broth to keep it moist, or use the microwave on medium power. Warm your pitas in a hot pan or toaster oven and add your fresh toppings and sauce just before serving for that just-made flavor!
