This oven-baked whole red snapper recipe is made with an entire butterflied fish covered in a Veracruz-style sauce with fire-roasted tomatoes, onions, bell peppers, garlic, oregano, and lime. The fish stays really tender, and the tomato sauce does most of the work when it comes to flavor.
I know cooking a whole fish can look intimidating, especially when it arrives with the head still attached. It’s actually easier than cooking individual fillets. Ask the fishmonger to clean, scale, and butterfly the snapper for you, and most of the work is already done.
This Veracruz-style red snapper is such a good dinner when you want something a little more exciting than basic baked fish. Serve it with rice, tortillas, or a simple salad and spoon plenty of that tomato sauce over everything.
Why You’ll Love This Recipe
- The fish stays tender. Baking red snapper whole helps protect the flesh from drying out. The bones also help the fish cook evenly and stay juicy.
- Most of the preparation is simple. The fishmonger can handle the messy part. At home, you only need to make the sauce, season the snapper, and put everything in the oven.
- The sauce is really flavorful. Fire-roasted tomatoes, onion, garlic, bell pepper, oregano, and lime make a savory sauce that works its way into the slashes in the fish.
- It’s made for sharing. A whole roasted red snapper looks impressive in the middle of the table, even though the actual preparation is pretty straightforward.
- You can adjust it. Add olives, capers, or jalapeños for a more traditional Veracruz sauce, or leave it mild as written.
What Is Veracruz-Style Fish?
Fish Veracruz style, or pescado a la Veracruzana, is a Mexican fish preparation associated with the coastal state of Veracruz. It usually combines fish with a tomato-based sauce containing onions, garlic, herbs, peppers, olives, and capers.
Red snapper is traditionally used and is called huachinango in Mexico, which is why you may also see the dish called huachinango a la Veracruzana. Other firm white fish can work, but a whole red snapper is especially good because it can handle the sauce without falling apart.
My version is best described as Veracruz-style fish because it keeps the tomatoes, onions, garlic, peppers, oregano, parsley, and lime but does not require olives or capers. You can absolutely add them if you want that salty, briny flavor.
Oven-Baked Whole Red Snapper Recipe Ingredients
You’ll only need a few simple ingredients to make this recipe. The exact measurements are listed in the recipe card below. Here’s an overview of what you’ll need:
Whole red snapper: Look for a fish with firm flesh, clear eyes, bright red or pink gills, and a clean ocean smell. It should not smell aggressively fishy. Ask the fishmonger to clean, scale, and butterfly it while keeping the head attached.
Fire-roasted tomatoes: These give the sauce more flavor without requiring you to roast fresh tomatoes first. Regular canned diced tomatoes will also work.
Onion: Yellow or white onion both work. Two cups may seem like a lot, but the slices soften into the sauce as the fish cooks.
Bell pepper: Use any color you have. Red and yellow peppers are sweeter, while green bell pepper gives the sauce a slightly more savory flavor.
Garlic: Four cloves give the sauce plenty of flavor. Fresh garlic is best here.
Oregano: Mexican oregano is great if you have it, but regular dried oregano works too.
Parsley: The parsley goes inside the butterflied fish and flavors it as it roasts. Cilantro can be used if that’s what you have.
Lime: Fresh lime juice brightens up the tomato sauce. Lemon works in a pinch, but I prefer lime for this Mexican red snapper recipe.
Olive oil: The oil softens the vegetables and gives the tomato sauce a richer texture.
Kosher salt: Season the fish inside and out. A large whole fish needs more seasoning than a small fillet.
See recipe card for quantities.
How to Make Oven-Baked Whole Red Snapper
Preheat the oven to 425°F. Line a large rimmed baking sheet or roasting pan with parchment paper.
Open the butterflied fish and season the inside and outside generously with kosher salt. Cut five parallel, 3-inch slashes into each side, stopping just before you reach the bone. These cuts help the fish cook evenly and give the sauce somewhere to go.
Stuff the parsley inside the cavity and place the snapper on the prepared pan.
Heat the olive oil in a medium skillet over medium heat. Once the oil is shimmering, add the sliced onion and bell pepper.
Cook for 3–5 minutes, stirring occasionally, until the vegetables begin to soften. Add the garlic and cook for about 30 seconds. Don’t let it burn. Burned garlic has a way of making everything about itself.
Add the oregano and fire-roasted tomatoes. Bring the mixture to a gentle boil, then lower the heat and simmer for 5–7 minutes. The vegetables should be soft and the sauce should thicken slightly.
Stir in the fresh lime juice and season with salt to taste.
Spoon the tomato sauce over the entire fish. Work some of the onions, peppers, and tomatoes into the slashes and add a little sauce inside the cavity too.
Place the fish in the oven and bake for 20–30 minutes. Baste it with the tomato sauce once or twice while it cooks.
The exact time will depend on the thickness of the fish. It is done when the flesh is opaque, flakes easily with a fork, and reaches 145°F in the thickest area.
Let it rest for about five minutes before serving.
My Top Tip
Don’t decide whether the fish is done based on time alone. Check the thickest part near the backbone. The flesh should pull away easily and look opaque but still moist.
A quick-read thermometer is really useful when you cook a whole fish. Insert it into the thickest part without pressing it directly against the bone.
Substitutions
Fish: If red snapper isn’t available, use another whole firm white fish such as sea bass, branzino, or porgy. Ask the fishmonger for a fish close to three pounds so the cooking time stays similar.
Canned tomatoes: Regular diced tomatoes work if you cannot find fire-roasted tomatoes. You can also use chopped fresh tomatoes, although the sauce may need a few extra minutes to reduce.
Parsley: Cilantro is the easiest substitute and gives the recipe even more Mexican flavor.
Bell pepper: Any color works. Poblano pepper is also a good option if you want a deeper flavor with a little heat.
Lime: Use fresh lemon juice if needed.
Olive oil: Avocado oil or another neutral cooking oil can be used, although olive oil contributes more flavor to the sauce.
Veracruz-Style Red Snapper Variations
Make it more traditional: Add about ½ cup of sliced green olives and 2 tablespoons of drained capers to the tomato sauce. This will bring the recipe closer to a traditional pescado a la Veracruzana.
Add some heat: Cook sliced jalapeño with the onion and bell pepper, or add pickled jalapeños to the finished sauce.
Use individual portions: You can make this with red snapper fillets or another white fish. Place the fillets in a baking dish, cover them with sauce, and begin checking them after 10–12 minutes.
Add potatoes: Arrange parboiled baby potatoes around the fish before adding the sauce. They’ll absorb the tomato, lime, and oregano as everything roasts.
Finish with more herbs: Add chopped parsley or cilantro right before serving for a fresh finish.
What to Serve with Veracruz-Style Fish
Rice is my first choice because it catches all that tomato sauce. My Instant Pot Cilantro Lime Rice is especially good here.
You can also serve the fish with warm corn tortillas, avocado, refried beans, or a simple green salad. If you want to make a larger Mexican seafood dinner, start with my Shrimp Aguachile and make a Tamarind Margarita. Honestly, that’s a very good meal.
If you have extra snapper but don’t want another whole-fish recipe, try my Panko-Crusted Snapper. My Ensenada Fish Tacos are another good option when you’re in the mood for Mexican fish.
If this recipe earns a spot in your regular rotation, you can write it down and keep it in my Cilantro Parsley Recipe Card Box Set. I still love having a physical copy of the recipes I make all the time.
Make Ahead
The Veracruz-style tomato sauce can be made up to two days ahead. Let it cool, store it in an airtight container in the refrigerator, and gently reheat it before spooning it over the fish.
I would not season the snapper too far in advance. Prepare and salt it shortly before baking so the texture stays firm.
How to Store Baked Red Snapper
Refrigerator: Remove the remaining fish from the bones and store it with some of the tomato sauce in an airtight container. Refrigerate it for up to three days.
Freezer: Cooked snapper can technically be frozen, but the texture is much better when eaten fresh. If you do freeze it, remove all the bones first and store the fish with sauce for up to two months.
Reheating: Place the fish and sauce in a covered baking dish and warm it at 300°F until heated through. You can also reheat individual portions gently in a skillet. Avoid blasting it in the microwave for too long or it will dry out.
Leftover fish is also really good tucked into warm tortillas with avocado and lime.
Frequently Asked Questions About Whole Red Snapper
How long do you bake a whole red snapper?
A three-pound whole red snapper generally takes about 20–30 minutes at 425°F. The thickness of the fish matters more than its total weight, so check the thickest part for doneness.
What temperature should red snapper reach?
Cook red snapper to an internal temperature of 145°F. Insert the thermometer into the thickest part of the flesh without touching the bone.
How do you know when whole red snapper is done?
The flesh should be opaque, moist, and easy to separate from the backbone with a fork. If it still looks translucent or resists flaking, give it a few more minutes.
Does red snapper taste fishy?
Fresh red snapper has a mild, slightly sweet flavor and should not taste strongly fishy. If the raw fish has a harsh fishy or ammonia-like smell, don’t use it.
Do I need to remove the head before baking the fish?
No. Leaving the head on is common when making a whole baked red snapper and helps create the classic presentation. You don’t have to eat anything from the head if you don’t want to.
Is Veracruz-style fish spicy?
Not necessarily. This version is mild because it uses bell pepper rather than chile. Add jalapeño or another chile if you want heat.
Can I use red snapper fillets?
Yes. Spoon the Veracruz sauce over the fillets and bake until they reach 145°F, usually about 10–15 minutes depending on their thickness. The result will still be good, but a baked whole red snapper stays especially moist.
