Low-sodium

Low-sodium fish dinners

Fish dinners stay lower in sodium when you skip soy sauce and salty spice rubs. Lemon, dill, and olive oil are enough for salmon or cod.

This page uses larger type. It is cooking help, not a medical plan.

In the portions written below, protein is about 32–42 g, calories about 320–430, and sodium about 140–340 mg. Those are rounded kitchen estimates before extra cheese, bread, or a heavy pour of sauce.

Shrimp has more natural sodium than white fish. The portion size matters more with shrimp.

How to run it

  1. Start with lemon shrimp and zucchini skillet. Plan on about 20 minutes. Sear the shrimp in oil 1–2 minutes a side, until they curl and turn opaque. Pull them out.
  2. Next, no-salt tuna and chickpea box. Regular canned tuna is often 250–400 mg of sodium in a small can. The no-salt-added label is the difference between a lunch and a salt bomb.
  3. Keep baked cod with spinach and potatoes for the meal that needs to feel different. Fridge 2 days. Cooked white fish is poor from the freezer.
  4. Cool anything you will not eat right away within two hours. For baked cod with spinach and potatoes: Fridge 2 days. Cooked white fish is poor from the freezer.

Shrimp carries more natural sodium than chicken. This recipe adds none. If your target is very low, weigh a smaller portion and fill the plate with zucchini and rice.

Ingredients

  • 1 1/4 pounds peeled shrimp
  • 2 zucchini, half-moons
  • 2 garlic cloves, sliced
  • 1 tablespoon olive oil
  • 1 lemon
  • 1/4 teaspoon red pepper flakes, optional
  • a handful of parsley
  • cooked rice or bread, if you want more food

Method

  1. Sear the shrimp in oil 1–2 minutes a side, until they curl and turn opaque. Pull them out.
  2. Cook the zucchini and garlic 4 minutes. Add a squeeze of lemon.
  3. Return the shrimp, toss, and finish with parsley. Shrimp go rubbery if they stay in the pan.

Fridge 2 days. Shrimp does not improve with age. Freeze raw shrimp in the marinade, not the finished skillet. If you serve it hot, reheat to 165°F with a food thermometer.

Storage times are general guidance, not a lab test of this recipe. A shorter package or recipe instruction governs. Freezing and reheating do not rescue food left out too long, or a heat-stable toxin that already formed. USDA FSIS: Leftovers and Food Safety.

Chill cooked rice promptly. Vomiting-type Bacillus cereus illness is generally tied to rice and other starchy foods, and that emetic toxin can survive heat that kills the bacteria. FDA Bad Bug Book: Bacillus cereus.

Cod is mild and already tender. If chewing is hard, flake it into the potatoes instead of serving it as a fillet.

Ingredients

  • 2 cod fillets, about 6 ounces each
  • 2 handfuls spinach
  • 2 medium potatoes
  • 1 tablespoon olive oil
  • 1 lemon
  • 1 garlic clove
  • black pepper

Method

  1. Microwave or boil the potatoes until tender. Mash them with a teaspoon of oil and pepper, no salt.
  2. Heat the oven to 400°F. Lay the cod on spinach and garlic in a small dish. Drizzle the rest of the oil and lemon.
  3. Bake 12–15 minutes, until the fish flakes easily.

Fridge 2 days. Cooked white fish is poor from the freezer. If you serve it hot, reheat to 165°F with a food thermometer.

Details that matter

  • Cook in water or unsalted homemade stock. Carton broth is often 600–800 mg per cup.
  • Buy no-salt-added beans and tomatoes. Rinse anything that did come from a salty can.
  • Build flavor with garlic, onion, ginger, citrus, vinegar, pepper, herbs, and spices that do not say 'seasoning salt.'

Easy mistakes

A seasoning packet

Chili, taco, onion soup, and ranch packets are salt with a spice cameo. Use the spices listed in the recipe instead.

Hidden salt in the 'healthy' add-ins

Cottage cheese, soy sauce, and rotisserie chicken can wipe out an otherwise careful plate.

Grocery starter

  • 1 1/4 pounds peeled shrimp
  • 2 zucchini, half-moons
  • 2 garlic cloves, sliced
  • 1 tablespoon olive oil
  • 1 lemon
  • 1/4 teaspoon red pepper flakes, optional
  • a handful of parsley
  • cooked rice or bread, if you want more food
  • 1 can no-salt-added tuna in water, drained (about 5 ounces)
  • 1/2 cup no-salt-added chickpeas, rinsed
  • 1 rib celery, diced, optional
  • 1 tablespoon lemon juice

Questions

How should I store lemon shrimp and zucchini skillet?

What is the easy mistake here?

Shrimp has more natural sodium than white fish. The portion size matters more with shrimp.
