Ingredients
Gather these simple pantry and fridge staples for a complete, satisfying meal.
- 1.5 lbs beef steak, cubed
- 1.5 tsp salt
- 1 tsp black pepper
- 2 large onions, sliced
- 2 tbsp olive oil
- 1/4 cup broth or water
- 2 lbs yellow potatoes
- 4 tbsp butter
- 1/2 cup heavy cream or milk
- Fresh chives for garnish
If you prefer a lighter sauce, swap heavy cream for whole milk or a splash of reserved potato water. Any well-marbled steak cut works; sirloin or ribeye both deliver great results. Fresh chives can be replaced with parsley if needed.
Step-by-step instructions
Follow these clear steps to build layers of flavor and achieve perfect texture every time.
Step 1: Season the steak cubes
Place the cubed beef in a large bowl and sprinkle evenly with salt and black pepper. Toss thoroughly so every piece is coated for maximum flavor during searing.
Step 2: Slice the onions
Peel the onions and cut them into thin, even slices on a cutting board. Uniform slices ensure they soften and caramelize at the same rate in the pan.
Step 3: Cook the onions
Heat olive oil in a skillet over medium heat and add the sliced onions. Season lightly with salt, then pour in broth and cook until soft and golden, stirring occasionally.
Step 4: Prep and mash the potatoes
Peel the potatoes, cut into chunks, and boil until fork-tender. Drain, then rice or mash them into a bowl with butter and cream until smooth and creamy.
Step 5: Sear the steak
Heat a hot skillet with a little oil and add the seasoned steak cubes in a single layer. Sear without moving them until a deep brown crust forms on one side.
Step 6: Finish cooking the steak
Flip the cubes and continue searing until all sides are browned yet the centers remain juicy and pink. Work in batches if needed to avoid crowding the pan.
Step 7: Plate the mashed potatoes
Spoon a generous mound of creamy mashed potatoes onto each plate and create a slight well in the center. This holds the steak and sauce beautifully.
Step 8: Assemble and garnish
Arrange the seared steak bites over the potatoes, spoon the onion sauce on top, and finish with a sprinkle of chopped chives. Serve immediately while hot.
Tips & common mistakes
A few small details make the difference between good and great results.

- Use a potato ricer for the lightest, lump-free mash

What to serve with this recipe
These simple sides and drinks complete the plate without overpowering the main flavors.

- Crusty bread to mop up remaining sauce
Frequently asked questions
These answers cover the most common questions home cooks ask about this dish.
Can I make the mashed potatoes ahead of time?
Yes, prepare them up to a day in advance and reheat gently with a splash of cream or milk to restore the silky texture before serving.
What cut of beef works best for steak bites?
Sirloin, ribeye, or tenderloin all work well. Choose a well-marbled cut so the cubes stay juicy and develop a nice crust when seared.
How do I keep the steak from overcooking?
Sear over high heat and remove the cubes as soon as they are browned on all sides. Residual heat will finish cooking them gently.
Can I freeze leftovers?
The steak freezes reasonably well, but mashed potatoes can become grainy. Store components separately and reheat the mash with extra liquid for best results.
