To roast a red snapper at 400°F (200°C), the cooking time generally depends on the size of the fish. For a whole red snapper, about 2 pounds, plan to roast it for about 15 to 20 minutes per pound.
The fish should be cooked until the flesh flakes easily with a fork and reaches an internal temperature of 145°F at the thickest part. Be sure to check the fish around the 20-minute mark to avoid overcooking.

Oven Roasted Red Snapper Recipe
The snapper of the day is the Blackfin Snapper. The Blackfin Snapper (Lutjanus buccanella) is found in the Atlantic Ocean, the Gulf of Mexico, and the Caribbean Sea. It has a red body with a silvery-white underbelly.
Although this snapper is red, it's called a Blackfin Snapper. Its identifying feature is the black spots on its pectoral fins.
According to Florida Fish and Wildlife Conservation Commission, the Blackfin Snapper can grow up to 30 inches in length.
Where To Get a Fresh Red Snapper
Come on down to the Keys and hop on a fishing charter. We have a lot of fish down here!
Or you can go to a reputable fish market. When buying fish, the fish should feel firm and it should smell like the ocean with clear, bright eyes and firm, shiny flesh.
Get the freshest snapper the store has.
You can use red snapper, yellowtail, mango or mangrove snapper, gray snappers, and mutton snappers, to name a few. Any type of snapper or small white fish can be used with this recipe.
Seasonings For Baked Fish
This fish is seasoned with Mediterranean-style seasonings including oregano and parsley, garlic, lemon, and olive oil.
A sprinkle of Old Bay seasoning, sea salt, and black pepper enhances the flavor.
How to Roast A Whole Fish
Roasting a whole fish at home is easy to do. You can have your fishmonger gut and descale your fish when you purchase it.
The outside of the fish is brushed with olive oil and seasoned with salt and pepper and then the cavity is stuffed with herbs.
I've surrounded the fish with lemon slices, slivered onions, chili peppers and little red potatoes that bake in the same time as the pound and a half fish.
The whole stuffed fish dinner is cooked in 20 minutes. It's so easy to make, and I'm sure you'll love it as much as we do.

How to Roast a Whole Red Snapper
- Preheat the oven to 400 °F (200 °C) and line a large sheet pan or 13 x 9-inch baking dish with parchment paper. Set the rack in the center of the oven.
- Rinse the fish under cold water and pat it dry with paper towels.
- Make three deep slashes on each side of the fish.
- Smash the garlic with the flat side of a chef’s knife, peel and trim. Chop coarsely.
- Mix the garlic with the fresh oregano, parsley, Old Bay, a tablespoon of olive oil, salt, and pepper.
- In a large bowl, toss the potatoes and a tablespoon of oregano leaves with one tablespoon of olive oil, one teaspoon of salt, and some black pepper.
- Brush or rub olive oil on the outside of the fish. Season with salt and pepper inside and outside the fish.
- Stuff the inside of the fish with the garlic-oregano mixture.
- Insert a few lemon slices, red onion, and a few sprigs of fresh herbs over the garlic oregano mixture in the cavity of the fish.
- Place the fish on the sheet pan. Arrange the potatoes, onions, and lemons (face down) around the fish.
- Roast for 20 minutes, without turning, or until the fish is opaque and flakes easily with a fork.
- Transfer the fish to a serving platter. Scatter the potatoes, onions, and lemons around the fish. Garnish the fish with flaky sea salt.
How Long to Bake a Red Snapper
A one-and-a-half-pound stuffed fish takes about 20 minutes to cook through. The internal temperature should reach 145 °F (63 °C) with an instant-read meat thermometer, and the flesh will be white and opaque when finished.
When the fish is cooked through, the flesh will flake when you drag a fork through it. There shouldn’t be any resistance. If there is, or the fish is not white and still translucent, roast another 10 minutes or so.
For a larger fish, increase the cooking time proportionally. Cook fish for 10 minutes per inch of thickness at the thickest part at 400°F (200°C).
For example, if your 1.5-pound fish took 20 minutes, a 3-pound fish will take around 40 minutes.
What Kind of Potatoes Goes with Fish?
If you have larger russet or Yukon Gold potatoes, peel them and cut them into 1-inch cubes. Season them the same way as the whole little red potatoes.
- I'm using Tiny Red Potatoes, to roast alongside the snapper to make this a complete fish dinner in one pan.
- Oven Roasted Yukon Gold Potatoes
- Roasted Russet Potatoes
- Poached Garlic Mashed Potatoes
Leftovers and Reheating
Store any leftovers in an airtight container in the refrigerator for up to 2 days.
Reheat leftover fish and potatoes in a small skillet with a little olive oil until heated through.
To reheat a whole fish, wrap the fish in aluminum foil and place in a 350 degree oven for 10 minutes.
Stuffed Red Snapper Recipe
This red snapper sheet pan meal is extraordinary! Roasting snapper on a sheet pan makes for an easy meal with minimal cleanup.
A Florida native, blackfin snapper is stuffed with seasonings, including lemon, oregano, parsley, Old Bay, and olive oil.
Little red potatoes, sliced red onions, and red chili peppers are seasoned with olive oil, salt, and pepper, and scattered around the fish.
Bake the fish in a 400-degree oven for 20 minutes until the flesh easily flakes when pierced with a fork.
Enjoy this healthy, flavorful dish for a weeknight dinner or a special occasion.

Frequently Asked Question
Blackfin snapper is good to eat. It has a firm texture and a mild, sweet flavor and definitely not fishy! It can be prepared by grilling, baking, roasting whole and frying.
For a whole fish with bones, figure about 1 pound per person. This accounts for the weight of the bones, other inedible parts.
Yes, you can use frozen snapper. Make sure to thaw it completely in the refrigerator before cooking.
Vegetables like fresh cherry tomatoes, bell peppers, yellow onions, can all be chopped and scattered around the fish. If you have fresh zucchini or frozen vegetables, roast them in a different pan so it isn't wet.
