Bright, cozy, and fast: garlicky rockfish fillets are pan‑seared then finished in the oven with a lemon‑herb butter, piled over a bed of olive‑oil mashed Yukon gold potatoes and a tangle of sautéed winter greens. It feels like a restaurant plate but is realistic for a weeknight. I’ll use in‑season WA December produce (Yukon potatoes, kale/chard, citrus, onions, garlic) and rockfish, which is on a great sale, to keep this high‑value. Serves 2.

Instructions
- Prep: Heat oven to 400°F. Pat rockfish dry with paper towels. Line a small sheet pan with parchment or lightly oil it.
- Prep potatoes: Place potato chunks in a pot, cover with cold salted water by 1 inch. Bring to a boil on the stove, then simmer until very tender, 12–15 minutes.
- Season fish: In a small bowl, combine 1 Tbsp olive oil, 1/2 tsp salt, 1/4 tsp pepper, and half the lemon zest. Rub over both sides of the rockfish. Let sit while potatoes cook.
- Make lemon‑garlic butter: In another small bowl, mash 2 Tbsp softened butter with 1 minced garlic clove, remaining lemon zest, and a pinch of salt. Set aside.
- Start searing rockfish (stove): Heat a large oven‑safe skillet over medium‑high. Add 1 Tbsp olive oil. When shimmering, lay in the fillets (presentation side down). Sear 2–3 minutes until lightly golden.
- Finish rockfish in oven: Flip the fillets, dot the tops with lemon‑garlic butter, and transfer the skillet to the 400°F oven. Roast 5–8 minutes, depending on thickness, until fish flakes easily but is still moist. Remove and let rest 2 minutes. Squeeze 1–2 tsp lemon juice over the top.
- Drain & mash potatoes: When potatoes are very tender, drain well. Return to the warm pot. Add 1 Tbsp olive oil, 1/4 cup milk or half‑and‑half, 1/2 tsp salt, and black pepper. Mash until smooth and creamy, adding a splash more milk if needed. Cover to keep warm.
- Cook greens: While fish finishes, heat remaining 1 Tbsp olive oil in a medium skillet over medium. Add sliced onion and a pinch of salt; cook until softened and golden at edges, 5–7 minutes. Add chopped kale (or broccoli), 2 minced garlic cloves, and a pinch of red pepper flakes. Sauté 3–5 minutes until tender (add 1–2 Tbsp water and cover briefly if using kale and it needs help wilting). Taste and season with salt, pepper, and 1–2 tsp lemon juice.
- Plate: Spoon a bed of mashed potatoes onto each plate. Nestle a mound of garlicky greens alongside or on top. Place rockfish fillet over the potatoes, spooning the buttery pan juices over. Garnish with avocado slices if using and extra lemon wedges.
- Serve: Bring to the table hot. Leftovers reheat gently on the stove with a splash of water for the potatoes and greens; warm fish briefly in a low oven so it doesn’t dry out.
Health notes: Roughly 650–750 kcal per serving. High in protein and omega‑3s, with fiber‑rich greens and potatoes. Use less butter for a lighter plate; add extra greens for more volume and nutrients.
Drink pairing: A crisp Washington Sauvignon Blanc (try something from Chateau Ste. Michelle) or a light pilsner.
