Psari Plaki — Baked Fish with Tomato, Olives & Lemon

Equipment

• 13" x 9" (3.5 qt) baking dish (ceramic or metal)
• 10" skillet (nonstick or stainless)
• Chef's knife and cutting board
• Measuring cups and spoons
• Rubber spatula and wooden spoon
• Instant-read thermometer
• Oven mitts

Ingredients (serves 5)

• 2.5 lb firm white fish fillets (cod, haddock, or pollock), skin removed and patted dry
• 1 (28 oz) can crushed tomatoes
• 2 medium fresh tomatoes, diced (about 1.5 cups) ⁺
• 1 medium yellow onion, finely diced (about 1 cup)
• 2 garlic cloves, minced ⁺
• 9 oz pitted Kalamata olives, halved ⁺
• 4 tablespoons extra-virgin olive oil ⁺
• 2 tablespoons fresh lemon juice (about 1 medium lemon) ⁺
• 2 teaspoons dried oregano ⁺
• 2 teaspoons kosher salt ⁺
• 1 teaspoon freshly ground black pepper ⁺
• 1/4 teaspoon crushed red pepper flakes (optional)
• 2 tablespoons chopped fresh parsley or 1 tablespoon chopped fresh dill (optional garnish)

Practical substitutions:

• Fish: any firm white-fleshed fillet (haddock, pollock, tilapia); if fillets are thinner than 1 inch, reduce bake time by 4–6 minutes and monitor internal temperature.
• Kalamata olives: substitute pitted Castelvetrano or another firm black olive.

Cooking / Baking

• Oven temperature: 400°F
• Target internal temperature for fish: 145°F (at thickest point)
• Total cook time: active ~25 minutes baking; total elapsed including sauce simmer ~45 minutes

Instructions

1. Preheat oven to 400°F and set an oven rack to middle position.
2. Heat the 10" skillet over medium heat; add 2 tablespoons extra-virgin olive oil.
3. Add the diced yellow onion and sauté, stirring, for 6 minutes until soft and translucent (do not brown).
4. Add 2 minced garlic cloves and cook 30 seconds until fragrant.
5. Add the 28 oz crushed tomatoes and 2 diced fresh tomatoes, then stir in 1 teaspoon kosher salt, 1/2 teaspoon black pepper and 2 teaspoons dried oregano. Bring to a simmer and maintain a gentle simmer for 10 minutes, stirring occasionally, until the sauce thickens slightly.
6. Remove skillet from heat and stir in the 9 oz halved Kalamata olives, 2 tablespoons fresh lemon juice and the remaining 2 tablespoons extra-virgin olive oil (use the oil already measured for this dish). Stir to combine.
7. Spread the sauce evenly in the 13" x 9" baking dish. Arrange the fish fillets in a single layer atop the sauce and spoon a little sauce over each fillet. Sprinkle the remaining 1 teaspoon kosher salt evenly across the fillets (this completes the 2 teaspoons total) and the remaining 1/2 teaspoon black pepper evenly across the fillets (this completes the 1 teaspoon total).
8. Bake uncovered at 400°F for 22–25 minutes, until the thickest part of the fillet reaches 145°F and the fish flakes when checked with a fork. (If fillets are thinner than 1" thick, check after 18 minutes.)
9. Remove from oven at 145°F and let rest in the baking dish for exactly 2 minutes. Garnish with chopped parsley or dill if using and serve immediately at 5:00 PM.

Lemon-Roasted Potatoes

Not low-carb: potatoes.

Not paleo: yukon gold.

Equipment

• Large pot (at least 4 qt) with lid
• 18" x 13" rimmed baking sheet (half-sheet pan)
• Vegetable peeler, chef's knife, colander
• Large mixing bowl
• Measuring spoons and cups
• Spatula

Ingredients (serves 5)

• 3.5 lb Yukon Gold potatoes, peeled and cut into 1 1/2" chunks
• 4 tablespoons extra-virgin olive oil ⁺
• 2 garlic cloves, minced ⁺
• 2 tablespoons fresh lemon juice (about 1 medium lemon) ⁺
• 1 teaspoon dried oregano ⁺
• 2 teaspoons kosher salt ⁺ (use 1/2 teaspoon in the parboil water and 1 1/2 teaspoons to toss potatoes before roasting)
• 1 teaspoon freshly ground black pepper ⁺
• 1/4 cup hot water (to create steam in the roasting pan)

Practical substitutions:

• Potatoes: red potatoes or russets may be used; if using russets, increase olive oil by 1 tablespoon.

Cooking / Baking

• Oven temperature: 400°F
• Total cook time: active ~20 minutes; elapsed ~55 minutes (12-minute parboil + 40-minute roast)

Instructions

1. Place peeled and cut potatoes in the large pot and cover with cold water by 1 inch. Add 1/2 teaspoon kosher salt. Bring to a boil over high heat, then reduce to a brisk simmer and cook for 10–12 minutes until the surface is just beginning to soften but pieces still hold shape. Test with a paring knife; there should be slight resistance.
2. Preheat oven to 400°F while the potatoes simmer and position another rack to allow the fish baking dish and sheet pan to fit side-by-side if possible.
3. Drain the potatoes in a colander and return them to the empty pot over very low heat for 30 seconds to evaporate surface moisture. Transfer potatoes to a large mixing bowl.
4. Add the remaining 1 1/2 teaspoons kosher salt, 1 teaspoon black pepper, 2 minced garlic cloves, 2 tablespoons lemon juice, 4 tablespoons extra-virgin olive oil, and 1 teaspoon dried oregano to the bowl. Toss gently but thoroughly to coat every piece.
5. Spread potatoes in a single layer on the rimmed baking sheet without crowding. Pour 1/4 cup hot water into an empty corner of the pan (not over the potatoes) to create steam during the initial roast.
6. Roast at 400°F for 35–40 minutes, turning with a spatula twice (once at ~15 minutes and again at ~28 minutes) until the potatoes are golden-brown and tender when pierced. Remove from oven and transfer to serving dish; potatoes may hold warm for up to 10 minutes before service.

5. NOTES & ASSUMPTIONS

• Optional table-side items: extra lemon wedges, crushed red pepper flakes (for adults), extra olive oil and extra olives and feta.
• Global substitutions: any firm white fish may substitute for cod; Kalamata olives may be replaced with a firm black or green olive; dried oregano may be substituted for fresh (use 1 teaspoon dried = 1 tablespoon chopped fresh as an approximate swap).
• Child-safety notes: keep children away from the oven and stovetop during the 4:15–5:00 PM window when both oven and stovetop are in active use; use oven mitts and a stable surface when removing hot pans; be cautious of any small bones in fillets.
• Explicit timeline risk(s): the tightest execution window is 4:18–5:00 PM because the potatoes and the fish occupy oven capacity concurrently and the fish must finish exactly at 5:00 PM. If the oven cannot accommodate both pans side-by-side without crowding, heat circulation may alter roasting/baking times.
• Practical mitigation mindset (without changing the menu): before starting, verify both pans fit in the oven with at least 2" clearance between pans and the oven walls; if they do not fit, position the fish dish on the middle rack and the sheet pan on a lower rack and monitor potato color closely in the final 10 minutes; keep timers visible, and assign one timer to fish (4:35–5:00) and one to potatoes with scheduled turns.
• The latest safe start time: You can start as late as 3:43 PM for a 5:00 PM serve.
