Instructions
- Prep (oven): Heat oven to 425°F. Halve spaghetti squash lengthwise, scoop seeds, rub cut sides with 1 tsp olive oil, salt, pepper. Place cut-side down on a sheet pan.
- Roast squash (oven): Roast until easily pierced, 30–40 minutes (smaller squash cooks faster).
- Start sauce (stove): In a skillet, heat 1 tbsp olive oil over medium. Add onion and a pinch of salt; cook until softened, 4–5 minutes. Add garlic and (optional) red pepper; cook 30 seconds.
- Burst tomatoes: Add halved grape tomatoes; cook, stirring, until they slump and get jammy, 6–8 minutes. Stir in butter (optional) and lemon juice. Taste and adjust salt/pepper.
- Cook fish (stove): Push sauce to the edges of the skillet to make space (or use a second pan). Pat rockfish dry; season with salt/pepper. Add a drizzle of oil, then sear fish over medium-high until browned and flaky, about 2–3 minutes per side (thickness matters).
- Finish: Turn off heat. Spoon tomatoes/onions over the fish and scatter torn Thai basil to perfume the sauce.
- Serve: Scrape spaghetti squash into strands with a fork, season with a little olive oil, salt, pepper (and Parmesan if using). Top with rockfish and plenty of tomato-basil pan sauce.
Health notes: ~450–600 calories per serving. Lean protein + lots of veg; spaghetti squash keeps it lighter than pasta. Watch added oil/butter in the sauce if aiming lower-cal.
Drink pairing: Wine: Washington Sauvignon Blanc or Pinot Gris. Beer: a crisp lager or Kölsch-style ale.
