Why This Recipe Works
- Ultra-moist: Baking in individual parchment parcels traps steam so the cod never dries out.
- Calorie-controlled: Each generous 6-oz portion contains only 165 calories—plenty of room for sides.
- One-pan cleanup: The parchment doubles as a serving vessel; just toss after eating.
- Week-night speed: From fridge to table in 20 minutes flat—ideal for busy schedules.
- Meal-prep friendly: Season packets the night before; pop into the oven when you get home.
- Restaurant flavor: A finishing drizzle of quick lemon-dill reduction tastes like gourmet beurre blanc minus the butter.
- Sustainable choice: Wild-caught Alaskan cod is MSC certified and environmentally responsible.
Ingredients You'll Need
Great results start with quality building blocks. Here’s what to shop for and why each component matters.
- Cod fillets: Look for moist, translucent flesh with no fishy aroma. Pacific or Alaskan cod is firmer and more eco-friendly than Atlantic. Thicker center-cut pieces (at least ¾-inch) bake evenly. If frozen, thaw overnight in the refrigerator on a paper-towel-lined plate to wick away excess moisture.
- Fresh dill: Fronds should be feathery, bright green, and aromatic. Avoid any sliminess or yellowing. If fresh is unavailable, freeze-dried dill retains far more volatile oils than dried flakes; use one-third the amount.
- Lemon zest & juice: Organic lemons give you peace of mind since you’ll be zesting the peel. Roll the fruit on the counter before cutting to maximize juice yield.
- Garlic: One small clove micro-grated distributes pungent flavor without overpowering the delicate fish.
- Extra-virgin olive oil spray: A light mist (about ½ tsp) prevents sticking and promotes browning while keeping calories minimal.
- Sea salt & freshly ground pepper: Season the fish five minutes before baking so the salt can begin to denature surface proteins, locking in moisture.
- White wine (optional): Two teaspoons per packet add complexity and aromatic steam. Choose a dry, crisp variety such as Sauvignon Blanc. For an alcohol-free version, substitute low-sodium vegetable stock.
- Whole-grain mustard: Just ¼ tsp per fillet adds subtle depth and helps emulsify the sauce.
How to Make Low Calorie Baked Cod with Lemon and Dill for Dinner
Preheat & Prep
Position rack in center of oven and preheat to 400 °F (204 °C). Tear four 12-inch squares of parchment paper. Have four 15-inch pieces of kitchen twine ready.
Season the Fish
Pat cod very dry with paper towels. Mist both sides with olive-oil spray. Combine ½ tsp sea salt, ¼ tsp black pepper, and ½ tsp garlic powder in a small bowl; sprinkle evenly over fillets. Let stand at room temperature 5 minutes while you prep aromatics.
Assemble Packets
Place one parchment square on work surface. Fan 3 thin lemon slices in center; lay dill sprigs on top. Set a cod fillet over herbs. Dot with ¼ tsp whole-grain mustard, drizzle 2 tsp wine, and scatter additional dill. Fold parchment over fish; make overlapping ½-inch pleats to seal, creating half-moon shape. Tie once with twine to secure. Repeat.
Bake Until Flaky
Transfer packets to rimmed baking sheet. Bake 11–13 minutes for ¾-inch thick fillets (add 2 minutes for 1-inch). Fish is done when it flakes easily and registers 140 °F carry-over cooking will bring it to perfect 145 °F.
Make Quick Pan Sauce (Optional but Wow!)
While fish rests, pour juices from one packet into small skillet. Add 2 Tbsp fresh lemon juice, 1 Tbsp minced shallot, and 2 tsp capers. Simmer 90 seconds; swirl in 1 tsp cold butter or olive oil. Spoon over plated cod.
Serve & Garnish
Slide contents of each packet onto warmed plates. Shower with additional chopped dill, lemon zest curls, and freshly cracked pepper. Pair with roasted asparagus, cauliflower mash, or a lemony arugula salad.
Expert Tips
Don’t Overcook
Cod turns from silky to cottony fast. Set a timer 2 minutes less than you think; you can always return it to oven.
Flash-Chill Before Seasoning
15 minutes in freezer firms surface so salt adheres without drawing out moisture.
Colorful Veg Bundles
Add julienned bell pepper or zucchini ribbons in packet for built-in side dish.
Reheat Gently
Warm leftover fish 8 min at 275 °F wrapped in foil with splash of broth to restore moisture.
Variations to Try
- Mediterranean: Swap dill for oregano, add olives & cherry tomatoes to packets.
- Asian twist: Use cilantro, lime, splash of tamari, and grated ginger.
- Spicy Cajun: Replace dill with thyme and ¼ tsp smoked paprika plus cayenne pinch.
- Dairy-free creamy: Blend silken tofu with lemon juice for a faux hollandaise drizzle.
Storage Tips
Cod is best enjoyed fresh, but leftovers keep 2 days refrigerated in airtight container. Place fillet in shallow bowl, cover with damp paper towel, then plastic wrap to minimize odor. For longer storage, flake cold cod into green salads or fold into whole-wheat tortillas with salsa for next-day lunch. Do not freeze cooked fish longer than 1 month; texture becomes spongy upon thawing. If prepping raw packets ahead, assemble up to 24 hours early and refrigerate on sheet tray, loosely covered with plastic wrap. Add 2 extra minutes to bake time if cooking straight from fridge.
