What is the best fish for meal prep?

My top choice is salmon fillets! However, when it comes to meal-prepping fresh fish, I’ve found that several types work very well. So, I thought it would be helpful to categorize them into three main groups: white fish, oily fish, and shellfish.

Best White fish for meal prep

Let’s start with delicate, mild white fish. These lean, quick-cooking options are perfect for everything from easy weeknight meals to meal-prepped lunches. Their tender flakes and neutral taste make them very versatile.

Tilapia is da bomb for meal preppin’ on a budget. It’s got a mild, kinda sweet flavor that plays well with all sorts of seasonings. When cooked right, tilapia flakes up into the perfect lil’ bites of fishy goodness. Pop some cumin-lime tilapia on a taco, dice it up for a zesty fish salad, or get crazy with a cheesy tilapia chowder. So many options with this affordable frozen fish!

Benefits of using tilapia in meal prep

  • Affordable, mild flavor
  • Flakes beautifully when cooked right

Can’t go wrong with a classic like cod for meal prep magic. That flaky, velvety texture is off the charts. Cod stays so moist when you bake or grill it – doesn’t dry out into a sad fish jerky situation, ya know?

Slap some minced garlic or homemade pesto on the cod and toss it on a baking sheet together with some fresh veggies and 15 minutes later you will have a perfectly cooked meal. Or spice it up with some Cajun seasoning and soy sauce – cod can hang with all the flavors!

Benefits of cod for meal prep:

  • Delicate white flesh that flakes apart
  • Cooked fish stays moist for days
  • Mild taste complements any seasonings
  • Very easy to cook and defrost cooked fish

Pro tips and tricks when cooking cod:

  • Bake, grill, or pan-sear cod fillets until opaque and flaky, how long will depend on the thickness of the fish fillets
  • Let cod cool completely before refrigerating in meal prep containers
  • Store cod for 3-4 days maximum in the refrigerator
  • Reheat cod gently or use it in fish sandwiches and tacos

Halibut hack:

I recommend marinade before cooking. And baking cod fillets at 360°F (180°C) for 10-12 minutes depending on thickness. Serve with cauliflower rice and green beans.

If you’re looking to treat yourself, halibut is totally worth it! This firm, mild fish has a slightly richer taste than tilapia or cod. Get that pan-sizzling hot and sear some wild-caught fish for a restaurant-worthy meal.

Grilled halibut steaks with a sweet mango salsa? Uh, yes, please! Even an easy recipe of lemon butter halibut will get you excited about the week ahead. Halibut is fancy but approachable. Definitely a winner.

  • I marinate halibut in chimichurri or dry Italian herb rubs before cooking.

Best Oily Fish for Meal Prep

The next category is oily fish sometimes called red fish meat. Their rich flavor and fatty acid content make them perfect for cooking ahead. They usually are packed with omega-3 and vitamin D. The added fats keep these fish extra moist and satisfying.

Cooking up a big batch of mussels is perfect for having seafood ready for all week. The mussels steam quickly right in a flavorful broth. Sometimes all you need is some salt and pepper, fresh parsley, and a squeeze of lemon juice.

Some of my favorite cooking liquids for mussels:

  • Tomato garlic broth – tomato, white wine, garlic

Meal Prep Cooking Tips for Fish

When meal-prepping fish, start by patting the fillets dry and seasoning them however you like – this helps get a nice sear and infuse flavor. Cook the fish using your preferred method (baking, grilling, searing) just until it’s opaque and flaky in the center. Be careful not to overcook it or the fish will dry out.

Once cooked, let the fish cool completely before packing it into airtight containers to store in the fridge. Portion the fish into individual servings so they’re ready to grab for meals later on. Following these steps – drying, seasoning, cooking properly, cooling completely, and storing in sealed containers – will keep your meal-prepped fish tasting fresh and flavorful all week long.

The keys are controlling moisture, cooking gently to perfect doneness, and not letting the fish sit warm too long before refrigerating. With these simple tips, you’ll get delicious, healthy fish meals from your meal prep with no fuss.

Storing and Reheating Fish

Once your fish is cooked to tender, flaky perfection, it’s time to let it chill out! Letting it cool completely before storage is clutch for keeping that fresh-from-the-sea flavor locked in. I like to divide my fish up into individual portions in meal prep containers so they’re ready to grab and go.

In the fridge, your fish will keep for 3-4 days max. Any longer and you risk it getting stinky and weirdly textured – yuck! When you’re ready to eat, there are a few good ways to reheat it: gently in the microwave, in a low oven, or sautéed in a pan with some oil or sauce. The key is not to overcook it when reheating or it’ll get dry and lame.

And that’s it! Follow my tips for cooling, storing, and reheating and you’ll be meal-picking fish like a boss. Your tasty seafood dishes will be waiting for you all week thanks to your fish handling skills. Get meal preppin’ those fillets and have a fantastic week!
