Baked Rockfish with Mushrooms & Crispy Bacon
This video recipe shows a large red-colored rockfish fillet baked with mushrooms, onion, garlic, lemon, and crispy bacon. Because common market names such as “red rockfish” can refer to more than one Pacific rockfish species, this page does not assign a scientific species unless the fish is positively identified.
I have worked with Pacific rockfish and other North Pacific groundfish for more than 30 years. One practical point matters more than most recipe instructions: fillet thickness changes cooking time. A thick center-cut piece should not be cooked by the clock exactly like a thin fillet.
For more background, see our Rockfish Guide, browse the Rockfish Collection, or shop our Fresh Rockfish Fillets.
Why Fillet Thickness Matters
Thin rockfish fillets cook quickly, while thick center-cut portions need more time for heat to reach the middle. Instead of relying on a fixed number of minutes, use the suggested timing as a starting point and check the thickest part of the fish with an instant-read thermometer.
For food safety, cook finfish to an internal temperature of 145°F (63°C) at the thickest point.
Ingredients
- 2 rockfish fillets, about 6–8 oz each
- 4 strips thick-cut bacon
- 1½ cups sliced mushrooms, such as cremini or button
- 1 small yellow onion, finely chopped
- 2 cloves garlic, minced
- 1 tbsp olive oil
- ½ tsp smoked paprika
- ¼ tsp black pepper
- Salt to taste
- Juice of ½ lemon
- 1 tbsp fresh flat-leaf parsley, chopped
How to Bake Rockfish with Mushrooms & Bacon
- Preheat the oven: Heat the oven to 400°F (200°C). Lightly oil a baking dish.
- Cook the bacon: Cook until crisp. Remove it from the skillet and reserve about 1 tablespoon of bacon fat.
- Sauté the vegetables: Cook the onion and mushrooms in the reserved fat until softened. Add garlic, paprika, and black pepper and cook briefly until fragrant.
- Prepare the fish: Pat the rockfish dry, place it in the baking dish, and season lightly with salt.
- Add the topping: Spoon the mushroom mixture over the fish and crumble the bacon on top. Finish with lemon juice and a small drizzle of olive oil.
- Bake: Bake until the thickest part of the fish reaches 145°F (63°C). A ¾- to 1-inch fillet may take roughly 12–15 minutes, but thickness and starting temperature can change the actual time.
- Serve: Garnish with parsley and serve immediately.
Working with a Thick Rockfish Fillet
If the fillet is substantially thicker than 1 inch, consider lowering the oven temperature slightly and allowing additional cooking time so the center can finish without drying the exterior. You can also portion a very thick fillet into pieces of more consistent thickness before cooking.
A short refrigerated salt brine can be useful for seasoning thicker fish evenly, but brining is optional for this recipe. If you brine the fish, measure salt by weight for consistency, keep the fish refrigerated, and reduce additional seasoning before cooking.
Why This Combination Works
Rockfish has a mild flavor and a texture that works well with savory toppings. Mushrooms and onion add depth, bacon adds smoke and richness, and lemon balances the finished dish.

Frequently Asked Questions
What temperature should rockfish reach?
Cook finfish to an internal temperature of 145°F (63°C) at the thickest point.
Can I use skin-on rockfish?
Yes. Skin-on rockfish can be baked successfully. Place it skin-side down and check the thickest part for doneness.
Can I use the same timing for every rockfish fillet?
No. Thickness, starting temperature, oven performance, and portion size affect cooking time. Use time as a guide and internal temperature as the final check.
Is “Giant Red Rockfish” a specific species?
Not necessarily. Market names can be ambiguous, so a scientific species should only be stated when the fish has been positively identified.
Where can I find more rockfish recipes?
