Pat the steak cubes dry with paper towels.
Season generously with salt, pepper, and garlic powder.

Turn the steak cubes and cook another one to two minutes.
Remove from the skillet.
# Step 3 – Make the Garlic Butter
Reduce the heat to medium.
Add the butter, minced garlic, and thyme.
Cook for about one minute until fragrant.
Return the steak bites to the skillet and gently toss until every piece is coated in the garlic butter.
Sprinkle with fresh parsley.
# Step 4 – Serve
Spoon a generous portion of mashed potatoes onto each plate.
Top with the garlic butter steak bites.
Drizzle the remaining garlic butter from the skillet over everything.
Serve immediately while hot.
# Sophia’s Tips
The secret to juicy steak bites is cooking them over very high heat and avoiding overcrowding the pan.
Don’t stir constantly.
Let the steak develop a rich golden crust before turning it.
Always let the butter melt after lowering the heat so the garlic doesn’t burn.
