Instructions
- Heat the oven to 450°F for the potatoes. Put a sheet pan in the oven to preheat (helps crisping).
- Prep the potatoes: cut 12 oz Yukon Gold potatoes into 3/4-inch chunks. Toss with 1 1/2 tbsp olive oil, 1/2 tsp kosher salt, and black pepper. Carefully spread on the preheated sheet pan and roast at 450°F for 20–30 minutes, turning once, until crisp and tender.
- Make the citrus mojo: in a bowl, whisk 3 tbsp citrus juice (lemon and/or orange), 2 tbsp olive oil, 2 cloves grated/minced garlic, 1 tsp cumin, 1 tsp dried oregano, 1/2 tsp kosher salt, black pepper, and optional 1 tsp honey + optional 1 tsp grated ginger. Set aside.
- Prep the cauliflower for the grill: cut 1 lb cauliflower into bite-size florets. Toss with 1 tbsp olive oil, 1 clove minced garlic, 1/2 tsp kosher salt, and black pepper. (If florets are small, use a grill basket or skewer them.)
- Grill the cauliflower: preheat grill to medium-high. Grill cauliflower 8–12 minutes total, turning occasionally, until charred in spots and just tender. Transfer to a bowl and toss with 1–2 tbsp of the mojo.
- Season the tuna: pat 12–16 oz tuna steaks dry. Brush both sides with 1–2 tbsp mojo and season with black pepper (and a pinch more salt if needed).
- Grill the tuna: grill over high heat about 60–90 seconds per side for rare/medium-rare (tuna is best left pink). If your steaks are thicker, add 30–60 seconds per side. Rest 2 minutes.
- Serve: slice tuna. Plate with crispy roasted potatoes and grilled mojo cauliflower. Spoon extra mojo over tuna and potatoes. (Optional: quick salad with butter lettuce/romaine, olive oil, and a squeeze of citrus.)
Health notes: ~700–850 calories per serving. High-protein, omega-3 rich (tuna), plus filling potatoes and lots of veg. For lighter: reduce potatoes to 8 oz total and add a side salad.
Drink pairing: Tuna is meaty, but the citrus mojo pulls you toward fresh, mineral whites—or a chillable red. - Best styles: Albariño, dry Rosé (Provence-style), or Pinot Noir (light, lower-tannin). - Local WA pick: Chateau Ste. Michelle Rosé (easy find) or a WA Pinot Noir (Willamette is nearby too and works beautifully).
