Instructions
- Prep the potatoes: cut 12 oz Yukon gold potatoes into 1 1/2-inch chunks; add to a pot, cover with cold salted water by 1 inch, and bring to a boil on the stove.
- Heat the oven to 450°F. Line a sheet pan.
- Prep the asparagus: trim 12 oz asparagus; toss on the sheet pan with 1 Tbsp olive oil, 1/2 tsp kosher salt, and black pepper. Set aside.
- Cook the potatoes: boil the potato chunks 12–15 minutes until a knife slides in easily; drain well and return to the hot pot to steam-dry 1 minute.
- Smash the potatoes: add 1/2 Tbsp butter and 1 Tbsp olive oil to the pot; smash potatoes roughly with a fork or masher. Season with 1/2 tsp kosher salt and black pepper. Cover to keep warm.
- Roast the asparagus: put the sheet pan in the oven and roast 10–12 minutes until tender-crisp and lightly browned at tips.
- Prep the steaks: pat dry 1 lb petite sirloin (2 steaks). Season all over with 1 tsp kosher salt total and plenty of black pepper. Let sit at room temp 10 minutes while asparagus roasts.
- Sear on the stove: heat a large skillet (cast iron preferred) over medium-high until very hot. Add 1 Tbsp olive oil. Sear steaks 3–4 minutes per side for medium-rare (125–130°F) or 4–5 minutes per side for medium (135–140°F), depending on thickness.
- Rest the steaks: transfer to a plate and rest 5–8 minutes.
- Make the horseradish pan sauce (same skillet): lower heat to medium. Add 1 Tbsp butter and 2 minced garlic cloves; stir 20 seconds. Grate about 1 oz horseradish root directly in (or add 1–2 Tbsp prepared horseradish). Stir 10 seconds.
- Finish sauce: whisk in 2 Tbsp sour cream (or Greek yogurt), 1 tsp Dijon, and 1–2 tsp lemon juice (optional). Add 2–3 Tbsp water to loosen to a spoonable sauce. Taste and season with salt/pepper. Stir in 2 Tbsp chopped parsley.
- Serve: plate smashed potatoes and roasted asparagus; slice steak if you like and spoon horseradish sauce over top.
Health notes: ~650–700 calories per adult (steak ~7–8 oz cooked, potatoes, sauce). Healthiness: Moderate—high protein and iron; keep butter/sour cream modest and load up on asparagus for fiber/micronutrients.
Drink pairing: Lean-ish sirloin + horseradish wants medium body and fresh acidity. Go for Washington State Syrah (peppery, dark fruit) or a Columbia Valley Cabernet Sauvignon (structured but not too heavy). Local picks: Columbia Crest (Cab/Syrah) or Chateau Ste. Michelle Indian Wells Cabernet.
