These tender steak bites are seared in fragrant garlic butter, delivering a juicy and rich flavor. The dish is complemented by a vibrant avocado chimichurri, blending fresh herbs, lime, and a hint of heat for a refreshing contrast. Perfectly cooked sirloin cubes are lightly seasoned and quickly seared, then tossed in melted butter and garlic for a luscious coating. The avocado chimichurri adds brightness and freshness, making each bite balanced and satisfying. Ideal for a quick and flavorful main course.
The sizzle of steak hitting a hot skillet is one of those kitchen sounds that makes everyone stop what they're doing and migrate toward the stove. I started making these bite-sized pieces during a dinner party when I realized individual steaks would take forever to cook, and now it's the most requested dish at my table.
Last summer my friend Sarah stood over my stove, sneaking steak bites straight from the pan while claiming she was just quality control. The chimichurri was her idea, and she was right, it transforms this from great to unforgettable.
Ingredients
- 1.5 lb sirloin steak: Cut into uniform cubes so they cook evenly, and pat them completely dry before seasoning for the best sear
- Kosher salt and black pepper: Season generously, this is your main flavor layer for the meat itself
- 1 tbsp olive oil: Use this to get the pan hot enough for a proper crust without burning your butter
- 3 tbsp unsalted butter: This creates that garlic butter coating in the final minute, so use good quality butter
- 4 garlic cloves minced: Add these at the end so they mellow into the butter instead of burning
- 1 tbsp fresh parsley: Fresh finish brightens up all that rich butter
- 1 ripe avocado: Choose one that gives slightly but isn't mushy, it should hold its shape when diced
- ½ cup parsley and ¼ cup cilantro: The herb duo that makes chimichurri sing, chop them finely
- 2 tbsp red wine vinegar: This acid balances the creamy avocado and rich steak
- ⅓ cup extra-virgin olive oil: Use your best olive oil here since it's not being heated
- 2 garlic cloves minced: Raw garlic in the chimichurri gives you that fresh bite
- ½ tsp red pepper flakes: Adjust this to your heat preference, but some warmth is essential
- Juice of ½ lime: Adds brightness and helps keep the avocado vibrant green
Instructions
- Make the avocado chimichurri first:
- Whisk together the parsley, cilantro, vinegar, olive oil, garlic, red pepper flakes, salt, pepper, and lime juice in a medium bowl until well combined, then gently fold in the diced avocado so it doesn't mash.
- Get your steak ready:
- Pat the steak cubes completely dry with paper towels, then season them all over with the salt and pepper, letting them sit at room temperature while you heat the pan.
- Sear the steak bites:
- Heat the olive oil in a large skillet over high heat until it shimmers, then add the steak in a single layer, working in batches if needed, and let them sear undisturbed for 2 minutes before flipping.
- Finish with garlic butter:
- Cook the flipped steak for another 1 to 2 minutes for medium-rare, then reduce the heat to medium-low, add the butter and minced garlic, and toss everything for 1 minute until the steak is coated and fragrant.
- Bring it all together:
- Remove from heat, sprinkle with fresh parsley, and serve immediately with generous spoonfuls of that avocado chimichurri on top.
My dad tried to skip the chimichurri once, claiming he's a purist, but after one bite with the avocado sauce he went back for seconds and admitted I was right all along.
Getting That Perfect Sear
High heat and patience during those first two minutes are what create the caramelized crust. Every time you move the meat around, you're losing that beautiful browning, so trust the process and let the pan do its work.
Making It Your Own
Sirloin is perfect for this, but ribeye will give you more marbling and tenderness if you're feeling indulgent. The chimichurri also works beautifully on grilled chicken or roasted vegetables.
Timing Is Everything
Have your chimichurri made and your table set before you start cooking, because these steak bites are best served straight from the pan. The contrast between hot, buttery steak and cool, creamy sauce is pure magic.
- Let the meat rest for just 2 minutes after cooking if you can wait that long
- Extra chimichurri keeps in the fridge for 2 days and is fantastic on eggs
- Don't forget crusty bread for sopping up that garlic butter
This is the kind of meal that turns a random Tuesday into something worth celebrating around the table.
