Instructions
- Prepare the Steak Bites:
- Pat steak cubes dry with paper towels then sprinkle with salt and black pepper on all sides. This step helps create a beautiful sear.
- Sear the Steak:
- Heat olive oil in a large heavy pan over medium high heat until shimmering. Add the steak cubes in a single layer without crowding. Let them cook untouched for two to three minutes on the first side to get a deep golden crust. Flip and cook another two to three minutes on the other side. Work in batches if needed so you do not steam the meat.
- Make the Garlic Butter:
- Reduce heat to medium. Add the butter minced garlic and Worcestershire sauce directly to the pan. Stir gently letting the butter melt and bubble while the garlic turns fragrant. Baste the steak bites with this garlicky butter for flavor in every bite.
- Finish the Steak:
- Once the garlic is tender and the butter is foamy turn off the heat. Toss with fresh parsley so the herbs wilt just slightly and transfer steak bites to a serving plate keeping all that pan sauce.
- Prepare the Potatoes:
- While the steak cooks bring a large pot of salted water to a boil. Add the peeled potato chunks boil them for fifteen to twenty minutes until very tender when pierced with a fork.
- Mash the Potatoes:
- Drain potatoes thoroughly and return to the hot pot. Add the butter milk or heavy cream salt black pepper and garlic powder if using. Mash well until smooth and creamy. Adjust the consistency with more milk if needed. Taste and add salt or pepper as you like.
- Finish and Serve:
- Spoon generous portions of mashed potatoes onto plates. Top with hot steak bites and drizzle extra garlic butter from the pan over everything. Garnish with more parsley and a final crack of black pepper.

I always look forward to the moment I add the garlic to the pan that sizzle and fragrant rush is the highlight of cooking this dish. My family often gathers around the stove just for that irresistible smell alone.
Storage Tips
Keep leftovers in separate airtight containers in the fridge for up to three days. Steak bites can be gently reheated in a skillet over low heat while mashed potatoes rewarm well in the microwave with a splash of milk to keep them smooth. If you plan to freeze mash portion them in small bags and press out extra air.
Ingredient Substitutions
You can use strip steak or even boneless pork chops cut into cubes if that is what you have. For dairy free mashed potatoes use olive oil and any unsweetened non dairy milk. If you are out of fresh parsley try fresh chives for a different bright flavor.
