Background & Origin

This combination — buttery mashed or smashed potatoes paired with bite-sized pieces of seared steak — has roots in classic European comfort food and modern American home cooking. Think of it as a simplified steak-and-potatoes: the steak is cubed for quick cooking and the potatoes are dressed up with garlic and butter for rich, creamy texture.

Why it’s popular:

Minimal fuss, maximum flavor — steak bites cook fast and mashable potatoes are forgiving.
Great for portioning and leftovers.
Works with inexpensive cuts when sliced into cubes and quickly seared.

Fun kitchen science: browning the steak (Maillard reaction) adds complex savory flavors, while mashing hot potatoes with butter and garlic allows starches to absorb fat for a silky mouthfeel. What makes this version unique is the simple soy-soaked marinate for the steak cubes — it adds an umami lift and deepens the savory profile without extra steps.

Ingredients

450 grams faux-filet, cut into 2.5 cm cubes (room temperature)
1 teaspoon olive oil (for marinating and searing)
1 tablespoon soy sauce (adds umami; use low-sodium if preferred)
½ teaspoon onion powder (optional)
1 kg potatoes (Yukon Gold or russet), peeled or scrubbed
4 tablespoons unsalted butter (room temperature)
3–4 cloves garlic, minced (finely chopped)
Salt, to taste
Freshly ground black pepper, to taste

Notes:

Potatoes: Yukon Gold gives a creamier texture; russets mash fluffy and absorb flavors well.
Butter: room temperature helps it blend seamlessly into hot potatoes.
Garlic: if you prefer a milder garlic profile, sauté it briefly before mixing.

Step-by-Step Instructions

Marinate the steak cubes in olive oil, soy sauce, and onion powder for at least 30 minutes.
- Time: 30 minutes (or up to 2 hours in fridge).
- Tip: Bring steak to room temperature for even cooking.
In a skillet, heat oil over medium-high heat and sear the marinated steak cubes until browned and cooked to desired doneness.
- Temperature: medium-high (around 375°F / 190°C surface heat).
- Visual cues: steak should be deeply browned on the outside and slightly springy when pressed for medium-rare.
- Time: 2–3 minutes per side for 2.5 cm cubes, depending on preferred doneness.
- Tip: Don’t crowd the pan — work in batches if needed.

Meanwhile, in a separate pot, boil the potatoes until tender, then drain.
- Time: 15–20 minutes depending on size.
- Visual cue: a fork slides through easily when they’re done.
In the same pot, add butter and minced garlic to the drained potatoes, mashing them together until smooth.
- Tip: Return the pot to low heat for 30–60 seconds after adding butter to melt it and help the garlic release aroma before mashing.
- Visual cue: potatoes should look glossy and creamy, not gluey.
Season the mashed potatoes with salt and pepper to taste.
- Mini-tip: Start with 1 teaspoon salt and adjust; remember steak adds savory saltiness too.
Serve the garlic butter potatoes topped with the steak bites.
- Presentation: spoon a generous mound of creamy potatoes, top with warm steak bites, drizzle any pan juices.
- Time to table: total active time ~30 minutes (excluding marinating).

Helpful mini-tips:

Use a potato ricer for ultra-smooth potatoes; for rustic texture, mash lightly.
Let the steak rest 2–3 minutes after searing for juicier bites.
Save a little butter to finish the steak for added gloss.

Pro Tips & Common Mistakes

How to improve flavor:
- Finish the steak with 1 teaspoon butter in the pan for an extra glossy, flavorful sauce.
- Stir a splash of cream or milk into the potatoes for an extra creamy finish.
Texture tricks:
- Overworking potatoes yields gluey results; mash gently and stop when smooth.
- For chunkier bites, leave a few small lumps.
What NOT to do:
- Don’t overcrowd the skillet — that steams the steak instead of searing.
- Don’t add cold butter straight to cold potatoes — it won’t incorporate well.
Helpful shortcuts:
- Use pre-cubed steak from the butcher to save prep time.
- Microwave potatoes on high for 8–10 minutes to speed up boiling (pierce first).
Prep-ahead hacks:
- Marinate the steak the night before.
- Make the mashed potatoes ahead and reheat gently with a splash of milk and a pat of butter.

Variations & Substitutions

Vegan: Use plant-based steak cubes or marinated tempeh and swap butter for vegan butter or olive oil.
Gluten-free: Use tamari instead of soy sauce or gluten-free soy sauce.
Low-carb: Replace potatoes with cauliflower mash (steam cauliflower, blend with butter and garlic).
Kid-friendly: Cut steak into smaller, tender pieces; reduce garlic if kids are sensitive.
Extra creamy: Add 2–3 tablespoons heavy cream or a dollop of sour cream to the potatoes.
Spicy: Toss steak bites with crushed red pepper or a pinch of cayenne; add chili oil to finish.
Budget-friendly: Use sirloin tips or chuck steak cubed and seared; flavor from soy and butter compensates for leaner cuts.

Serving Suggestions

Best sides:
- Roasted green beans, steamed broccoli, or a simple lemony arugula salad.
Bread:
- Crusty garlic bread or warm dinner rolls to soak up pan juices.
Salads:
- Crisp mixed greens with a vinaigrette brightens the rich potatoes and steak.
Rice or pasta:
- Skip if you want a starch-free plate—this duo is hearty enough on its own.
Wine pairing:
- A medium-bodied red like Merlot or Malbec complements the steak; for white lovers, a oaked Chardonnay works with buttery potatoes.
How to plate beautifully for guests:
- Use a ring mold for potatoes, top with steak bites, garnish with chopped parsley and a lemon wedge for color and brightness.

Storage, Freezing & Reheating

Fridge:
- Store in airtight containers for up to 3–4 days.
Freezer:
- Potatoes can be frozen for up to 2 months (best quality). Steak bites freeze well for up to 3 months if tightly wrapped.
Reheating:
- Stovetop: gently reheat potatoes with a splash of milk and a pat of butter over low heat; warm steak in a skillet briefly to avoid overcooking.
- Oven: 350°F (175°C) covered for 15–20 minutes for combined leftovers.
Meal-prep options:
- Cook potatoes and steak separately, refrigerate, then reheat and assemble for lunches or quick dinners.
