Marinated baked fish with garlic, basil, and bell peppers

We often forget that, just like chicken and meat, delicate foods like fish can benefit from a little time in a tasty marinade.

As long as you keep the acid low and the marinating time short, marinating a firm fish or a fish fillet like halibut or cod can do some good.

The marinade will infuse the fish with all sorts of mouthwatering flavors. It will also keep the fish juicy while protecting it from sticking or drying out during grilling or baking.

So if you're wondering, "what's the best way to bake fish without drying it out?" One way is to bake your fish in foil, which I know can be a controversial method. But another way is to simply marinate your fish!

About this recipe 

Today's tender baked fish recipe could not be any easier to make.

I used halibut fillet (but another white fish of your choosing will work). The fillets sat in the fridge in a slightly lemony marinade with garlic, basil, and a few spices. I let it marinade in the fridge for only 30 minutes.

To bake, I added the fish and the marinade over a bed of colorful bell peppers and shallots and baked for about 15 minutes. Easy!

My family loved this fish served with lemon rice and a big bowl of Greek salad.

What's in the fish marinade?

You'll notice that I kept the citrus portion low using juice of 1 lemon (2 tablespoons of citrus) to 6 tablespoons of extra virgin olive oil.

Here's what is in my fish marinade:

  • Spices- a trio of dry oregano, coriander, and paprika.
  • Garlic- 10 fresh garlic cloves. I like to mince the garlic as finely as I can for maximum flavor.
  • Fresh basil- 15 fresh basil leaves, sliced into ribbons. The combination of fragrant fresh basil with the warm spices pack this fish marinade with great flavor. If you don't have basil, you can use parsley, cilantro, dill, or thyme to your liking.
  • Citrus- juice of 1 lemon, which is about 2 tablespoons of citrus. If you like, you can switch it out for lime, white wine, or a mild-tasting vinegar.
  • Extra Virgin Olive Oil- I used 6 tablespoons of Private Reserve Greek extra virgin olive oil. Because the fish bakes with the marinade, it's important to use a tasty oil that will enhance the fish.

How long to marinate fish? 

Like I mentioned earlier, when it comes to marinating fish, it's important to keep the acid low and the marinating time short.  I used juice of 1 lemon (2 tablespoons of citrus) to 6 tablespoons of extra virgin olive oil.

As far as how long you should marinate your fish can depend a bit on the kind of fish and how firm it is. In general, it's safe to marinate a fish fillet like halibut or even a flaky fish like cod for 30 minutes or so refrigerated.

If you're marinating a fairly thick fish steak like a tuna fish steak or a swordfish steak, you may go for 1 to 2 hours of marinating.

Always keep your marinated fish in the fridge.

How to Make this Baked Fish Recipe

There really are two steps to this fish fillet recipe

1. Season and Marinate Fish

Pat fish dry and season with salt and pepper.

Place the fish in a large zip-top bag and add spices, garlic, basil ribbons, olive oil and lemon juice. Seal shut. Refrigerate for 30 minutes.

Tip: Be sure to squeeze the air out of the zip-top bag before sealing. Place the bag flat on a plate and refrigerate. Turn the bag occasionally to keep the marinade distributed evenly.

2. Bake 

Heat the oven to 425 degrees F.

Slice shallots and bell peppers into rounds and arrange them on the bottom of 9 x 13 baking dish. Add the fish on top. Pour all the marinade all over the fish. Bake for about 15 minutes or until the halibut is fully cooked and flakes easily (start checking at 10 minutes or so).

To be sure your halibut (or fish fillet) is cooked, use an instant read thermometer to check at the thickest part of the fish. Internal temperature should register 145 degrees F and your fish should be opaque and should flake easily with a fork.

Serve with 

Serve baked fish immediately with your favorite grain or lemon rice and a side of Greek salad, white bean salad, or herbed zucchini.

Easy Baked Fish with Garlic and Basil

  • Yield: Serves 6

Description

Easy, tender baked fish infused with garlic and basil. The secret to this juicy fish is in the quick fish marinade with a few spices, garlic, fresh basil, a little citrus and extra virgin olive oil.

Serve it with lemon rice and my big white bean salad or any bright salad you love!


Ingredients

Scale
  • 2 lb fish fillet like halibut
  • Salt and pepper
  • 1 ½ tsp dry oregano
  • 1 tsp ground coriander
  • 1 tsp sweet paprika
  • 10 garlic cloves, minced
  • 15 basil leaves, sliced into ribbons
  • 6 tbsp extra virgin olive oil (I used Private Reserve Greek EVOO)
  • Juice of 1 lemon
  • 2 bell peppers any color, sliced (I used 1 red and 1 green bell pepper)
  • 2 shallots, peeled and sliced

Instructions

  1. Pat fish fillet dry and season with salt and pepper on both sides.
  2. Place the  fish in a large zip-top bag. Add the oregano, coriander, paprika, minced garlic, basil, extra virgin olive oil and lemon juice. Zip the bag shut and massage to be sure the fish is evenly coated in the marinade. Marinated for 30 minutes or up to 1 hour in the fridge (see notes).
  3. Heat oven to 425 degrees F.

  5. Bake in heated oven for 15 minutes or until fish is done and flakes easily.

Notes

  • Tip for how long to marinade fish: I used halibut fillet in this recipe and I typically marinate it about 30 minutes. Thicker fish steaks like tuna or swordfish could be marinated for 1 to 2 hours, but that is not the kind of fish I would recommend for this recipe.
  • How to know if your fish is cooked? To be sure your halibut (or fish fillet) is cooked, use an instant read thermometer to check at the thickest part of the fish. Internal temperature should register 145 degrees F and your fish should be opaque and should flake easily with a fork.

  1. Thank you so much for this recipe! We prepared with haddock filets & it was delicious. We marinated 4 filets in the suggested marinade for 1 hour & then baked for 15 minutes. The shallot & bell pepper base to set the filets on is just the best!
    We reduced the recipe for the two of us & grilled veggies for the side. This is my go to recipe now!

  2. I made this recipe exactly as written. It was delicious!! I highly recommend this recipe. It was different, and I paired it with the white bean salad, yum.....yum....yum!!! Another keeper! Thank you so much for the good tasting food.

  3. Just made this as a surprise for my wife! It was delicious! The only issue I have is that now this level of dish will now be expected from me! Lol I did add some capers and sun dried tomatoes because I can’t leave well enough alone. Turned out great

  4. Peppers and onions were still raw..not long enough for them to cook. Would be better to saute them 1st. Used cod..dish was ok but probably won't make again

  5. Oh my! This was so incredibly flavorful and super easy that I couldn't believe it! I used frozen cod, marinated 30 minutes and it was ready in about 20 minutes. I am going to try to make this weekly. Thanks a million!

  6. I can't seem to find sweet paprika locally and was hoping to make this dish sooner than ordering something online. can i use another kind of paprika or would you have a recommendation for a replacement? thank you.

  7. This recipe is so amazing! I could not find Halibut in our grocery store this time, so I used North Atlantic Cod. I love the cleanness of the flavors of this dish and so very tasty. The bell peppers and shallots give the dish a little touch of sweetness and balance out the citrus-herb without being overpowering. Like so many of your dishes that I've tried, Suzy, this is a keeper! Thank you!
