Ingredients
- Sirloin steak cut into bite-sized pieces: A tender and juicy cut that is easy to sear and absorbs the garlic butter flavors well Try to choose a cut with good marbling for best texture
- Unsalted butter: Richness for both the mash and the steak sauce Using unsalted lets you adjust seasoning perfectly
- Garlic minced: The flavor backbone here The fresher the better for brightest results
- Fresh thyme leaves: Brings a gentle herby note Use fresh for a pop of color and aroma or dried in a pinch
- Salt and pepper: Essential for seasoning both potatoes and steak Choose kosher salt and freshly ground pepper for greater depth
- Olive oil: Helps get a golden crust on the steak Look for extra virgin for clean flavor
- Yukon gold potatoes: Creamy when mashed and slightly buttery in flavor Select evenly sized potatoes to ensure they cook evenly
- Heavy cream: Makes the potatoes silky and rich Full-fat cream delivers the best result
- Fresh parsley chopped: A simple garnish that adds a burst of freshness and color Choose flat-leaf parsley for easier chopping and brighter taste
Step-by-Step Instructions
- Boil and Drain the Potatoes:
- Place peeled and cubed Yukon gold potatoes in a large pot and cover with cold water This ensures even cooking Bring to a gentle boil over medium-high heat then simmer uncovered for fifteen to twenty minutes until fork tender Drain well and return to the hot pot so any excess moisture evaporates
- Mash the Potatoes:
- Add two tablespoons of butter and half a cup of heavy cream to the steaming potatoes Begin mashing with a potato masher or ricer Continue mashing until completely smooth and creamy Taste and season generously with salt and pepper Keep the pot on very low heat to keep the mash warm while you finish the steak
- Sear the Steak Bites:
- Heat olive oil in a large heavy-bottomed skillet over medium-high heat Once shimmering add the steak pieces in one even layer Avoid crowding so each piece gets a good sear Cook undisturbed for two to three minutes until the first side has a golden brown crust Flip and cook another two to three minutes for medium doneness Remove steak to a plate and rest briefly
- Make the Garlic Butter Sauce:
- Lower the skillet heat to medium then add the last tablespoon of butter Allow to melt and gently swirl in minced garlic and thyme Cook just until the garlic is soft and fragrant which should take about one minute stirring to avoid burning
- Toss Steak Bites in Sauce:
- Pour the resting steak bites back into the skillet with the garlic butter Use a spatula or tongs to toss and coat evenly in the sauce Sauté another minute to rewarm and finish seasoning with more salt and pepper if needed
- Assemble and Serve:
- Spoon a generous pillow of mashed potatoes onto each plate Arrange hot steak bites over the top and drizzle over any remaining garlic butter Scatter chopped parsley for a final splash of color Add a side of vegetables if you like

Nothing beats watching everyone go back for seconds after that first garlicky bite My kids love scooping up every last drop of buttery sauce with their mash and the thyme perfumes the whole kitchen
Storage Tips
Leftover steak bites can be stored in an airtight container in the fridge for two days Reheat gently in a skillet with a splash of broth or water for best results Mashed potatoes can also be refrigerated for up to three days If freezing the potatoes let them cool completely before transferring to freezer safe bags They may need a little extra cream when reheating to regain smoothness
Ingredient Substitutions
If you do not have sirloin try flank steak ribeye or even chicken breast for a twist Replace heavy cream in the mash with milk or sour cream for a lighter option For added flavor try stirring roasted garlic into the potatoes or swapping thyme for rosemary
