Baked Mustard Salmon (Łosoś pieczony w musztardzie)

Equipment

• Rimmed baking sheet, 13 x 18 inch (quarter-sheet) lined with aluminum foil
• Small mixing bowl
• Measuring spoons
• Pastry brush or spoon
• Instant-read thermometer
• Kitchen tongs or fish spatula
• Cutting board and chef's knife
• Aluminum foil to tent

Ingredients

• Salmon fillets, skin-on — 24 oz (1.5 lb), 4 fillets ~6 oz each
• Whole-grain mustard — 3 tbsp
  • Substitution: If whole-grain mustard is unavailable, use 3 tbsp Dijon mustard.
• Honey — 2 tbsp
• Unsalted butter — 2 tbsp, melted ⁺
  • (Marked ⁺ because used also for potatoes)
• Lemon juice — 1 tbsp (from 1 small lemon)
• Fresh dill, chopped — 2 tbsp
  • Substitution: If fresh dill is unavailable, use 1 tsp dried dill (stir dried into glaze).
• Kosher salt — 1 tsp ⁺
• Ground black pepper — 1/4 tsp ⁺
• Olive oil for the sheet (thin brush) — 1 tsp

Cooking / Baking

• Oven temperature: 425°F
• Target internal temperature for salmon: 140°F (firm but moist for family service)
• Total cook time: 18 minutes (5 minutes active prep + 12 minutes bake + 1 minute tent/rest)

Instructions

1. Remove salmon from refrigerator when you begin the potatoes (see timeline). Pat fillets dry on a cutting board with paper towels. Place fillets skin-side down on a foil-lined rimmed baking sheet, leaving space between pieces.
2. In a small mixing bowl combine whole-grain mustard (3 tbsp), honey (2 tbsp), melted unsalted butter (2 tbsp), lemon juice (1 tbsp), chopped dill (2 tbsp), kosher salt (1 tsp), and ground black pepper (1/4 tsp). Stir until homogeneous.
3. Lightly brush the foil under each fillet with 1 tsp olive oil to prevent sticking. Spoon or brush the mustard-honey glaze evenly over the flesh side of each fillet — about 1 to 1.5 tbsp glaze per fillet.
4. Slide the baking sheet onto the middle rack of the preheated 425°F oven and bake 12 minutes. Check doneness with an instant-read thermometer in the thickest part of the fillet; target 140°F. If any fillet is under, return to oven and check every 1–2 minutes; do not exceed 145°F unless preferred.
5. When removed, tent the salmon loosely with foil for 1 minute (carryover keeps it moist). Plate immediately and serve at 17:00.

Oven-Roasted Baby Potatoes with Butter & Caraway

Equipment

• Rimmed baking sheet, 13 x 18 inch (quarter-sheet) — can roast potatoes on same sheet used for salmon if cleaned and staggered in oven schedule (timeline uses separate slots)
• Large mixing bowl
• Measuring spoons
• Spatula
• Oven mitts
• Tongs or spatula for shaking pan

Ingredients

• Baby potatoes (Yukon Gold or small red potatoes) — 2 lb (about 8 cups halved)
  • Substitution: If baby potatoes are unavailable, use 2 lb Yukon Gold or red potatoes, cut into 1-inch pieces.
• Olive oil — 2 tbsp
• Kosher salt — 1 1/2 tsp ⁺
• Ground black pepper — 1/2 tsp ⁺
• Caraway seeds — 1 tsp
  • Substitution: If caraway seeds are unavailable, use 3/4 tsp fennel seed or omit.
• Unsalted butter — 2 tbsp, cut into small pieces to toss after roasting ⁺

Cooking / Baking

• Oven temperature: 425°F
• Roast time: 35 minutes (toss/rotate at halfway)
• Total cook time: 45 minutes (10 minutes prep + 35 minutes roast)

Instructions

1. Preheat oven to 425°F. Line a rimmed baking sheet with foil.
2. Wash potatoes; halve any larger baby potatoes so pieces are roughly uniform (about 1-inch halves). Place in a large mixing bowl.
3. Add olive oil (2 tbsp), kosher salt (1 1/2 tsp), ground black pepper (1/2 tsp), and caraway seeds (1 tsp). Toss until all potatoes are evenly coated.
4. Spread potatoes in a single layer on the prepared rimmed baking sheet with space between pieces.
5. Roast on the middle rack at 425°F for 35 minutes. At 17–18 minutes (halfway), open oven, use tongs or shake the pan to turn potatoes, and return to oven.
6. At 35 minutes total, remove potatoes from oven to a warm heat-safe bowl or keep on the baking sheet tented lightly with foil. Immediately add unsalted butter (2 tbsp) and toss to coat; adjust salt if needed. Hold for up to 15 minutes before serving (do not exceed 15 minutes holding if you want crisp edges).

5. NOTES & ASSUMPTIONS

• Optional table-side item: extra whole-grain or Dijon mustard available for guests who want a stronger mustard note.
• Global substitutions: whole-grain mustard → Dijon (1:1); fresh dill → 1 tsp dried dill; baby potatoes → 2 lb Yukon Gold or red potatoes cut to 1-inch pieces.
• Child-safety notes: Keep children away from the oven during hot-open steps at ~16:10–16:12 and ~16:46–16:58. Use oven mitts and an instant-read thermometer to avoid repeated re-opening of the oven.
• Timeline risk(s): The tightest execution window is 16:40–17:00 (glazing and baking salmon while holding potatoes). Risk comes from oven crowding or a slow preheat. Mitigation: preheat the oven at 16:05, complete glaze assembly by 16:40, and clear the middle rack so salmon can go in immediately at 16:46. Have an instant-read thermometer ready to confirm salmon 140°F quickly.
• Practical mitigation mindset: Be deliberate about mise en place — measure the glaze ingredients while potatoes roast so glazing is a single quick step. If the oven under-performs, raise testing cadence by checking temps 1 minute early rather than extending cooking blind.
• Latest safe start time: You can start as late as 16:05 for a 17:00 serve.
