4. Assemble

Place salmon on parchment (skin-side down if applicable).
Pour sauce over top and layer lemon slices.

5. Create a Parchment Tent

Fold parchment loosely over the salmon to trap steam.

6. Cook

  • LOW for 1½ to 2½ hours
  • Start checking at ~1 hour 15 min

Salmon is ready when:

  • It flakes easily
  • Center is opaque
  • Internal temp: 125–130°F (juicy) or up to 140°F

7. Rest & Serve

Let rest 3–5 minutes. Spoon buttery sauce over the top and serve.


🍽️ Serving Ideas

This salmon shines with simple sides that soak up the sauce:

  • 🍚 White rice or buttered noodles
  • 🥦 Steamed green beans or asparagus
  • 🥗 Light salad with vinaigrette
  • 🥔 Mashed potatoes for a cozy meal
  • 🍞 Crusty bread to catch every drop

🔥 Tips for Best Results

  • Don’t overcook — salmon dries out quickly
  • Use fresh lemon for the brightest flavor
  • Keep parchment loose, not tightly sealed
  • Thicker fillets = longer cooking time

🔄 Variations

Make it kid-friendly:
➤ Reduce lemon + add 1–2 tsp honey for mild sweetness

Garlic lovers:
➤ Double the garlic + sprinkle Parmesan before serving

Lighter version:
➤ Use 2 tbsp butter + replace rest with broth
