There’s something truly magical about the taste of fresh rockfish, especially when it’s infused with the savory, aromatic embrace of Old Bay seasoning.

The aroma alone filled the kitchen with warmth, and the look on their faces as they took their first bite – pure bliss! It was then I realized the power of simple, quality ingredients combined with a touch of culinary creativity. This Rockfish with Crab and Old Bay Cream Sauce is more than just a meal; it’s a memory waiting to be made.

Recipe Overview

Prep Time: 8 minutes
Cook Time: 15 minutes
Total Time: 23 minutes
Servings: 6
Yield: 6 servings
Dietary Type: Pescatarian

Ingredients

1 ½ lbs rockfish or striped bass fillets
2 ½ teaspoons McCormick Old Bay Seasoning with Garlic and Herb, divided
3 tablespoons butter, divided
2 tablespoons white wine
1 green onion, finely chopped
1 cup heavy cream
2 teaspoons Dijon mustard
8 ounces lump crabmeat (or backfin)

Equipment Needed

Large skillet
Spatula

Instructions

Heat a large skillet on medium-high heat for 3 minutes. It’s important to get the pan nice and hot to ensure a good sear on the fish.
Melt 2 tablespoons of butter in the skillet. The butter will add richness and flavor to the fish as it cooks.
Season the flesh side of the rockfish or striped bass fillets with 1 ½ teaspoons of Old Bay seasoning. Don’t be shy with the seasoning – it’s what gives the dish its signature flavor.
Place the fish skin side up in the skillet. This ensures the flesh side gets beautifully browned.
Cook for 5 minutes, turning the fish after 3 minutes. The fish should be golden brown and slightly crispy on both sides. Use a thin spatula to carefully turn the fillets.
Remove the fish from the skillet and keep warm. You can place it on a plate and cover it loosely with foil.
Reduce the heat to medium. This prevents the sauce from burning or reducing too quickly.
Stir the white wine into the skillet, scraping the bottom to loosen any browned bits. This process, called deglazing, adds depth of flavor to the sauce. Make sure to scrape all the stuck-on bits to incorporate their flavor.
Add the remaining butter and green onion; cook and stir for 1 minute. The green onion will soften and release its aroma, infusing the butter with its delicate flavor.
Gradually stir in the heavy cream. Be careful to incorporate the cream slowly and stir constantly to prevent it from curdling or separating.
Stir in the Dijon mustard and the remaining Old Bay seasoning. The Dijon mustard adds a tangy kick to the sauce, while the Old Bay reinforces the dish’s signature flavor profile.
Simmer for 2 minutes, or until slightly thickened. The sauce should coat the back of a spoon. Don’t over-simmer, as the cream can become too thick and the sauce will lose its velvety texture.
Stir in the crabmeat. Be gentle to avoid breaking up the delicate crabmeat.
Return the fish to the skillet and cover. This will reheat the fish and allow it to absorb some of the delicious sauce.
Cook for 3 minutes longer, or until the fish flakes easily with a fork. The internal temperature of the fish should reach 145°F (63°C).

Expert Tips & Tricks

For an extra layer of flavor, try using a dry sherry instead of white wine to deglaze the pan.
If your sauce becomes too thick, add a splash of fish stock or chicken broth to thin it out.
To prevent the cream from curdling, use heavy cream and avoid boiling the sauce.
Make sure your crabmeat is well-picked to avoid any shells in the final dish.
A squeeze of fresh lemon juice at the end brightens up the flavors beautifully.
To ensure even cooking, use fillets of similar thickness. If some fillets are thicker, they may require a minute or two of extra cooking time.
If you prefer a richer sauce, you can add a tablespoon of mascarpone cheese at the end for extra creaminess.
Don’t overcrowd the pan when cooking the fish. If your skillet is small, cook the fillets in batches.

Serving & Storage Suggestions

Serve the Rockfish with Crab and Old Bay Cream Sauce immediately over a bed of steamed rice, creamy mashed potatoes, or alongside some roasted asparagus. Garnish with a sprinkle of fresh parsley or a lemon wedge for added visual appeal.

Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. Reheat gently in a skillet over low heat, adding a splash of cream or broth if needed. Microwaving is not recommended as it can make the fish rubbery. This dish is best enjoyed fresh. Freezing is not recommended because the sauce may separate upon thawing.

FAQs (Frequently Asked Questions)

Q: Can I use frozen rockfish fillets for this recipe?
A: Yes, you can. Just make sure to thaw them completely before cooking and pat them dry with paper towels to remove excess moisture.

Q: What if I can’t find rockfish or striped bass?
A: You can substitute other firm white fish fillets such as cod, haddock, or mahi-mahi. Adjust the cooking time slightly depending on the thickness of the fillets.

Q: Can I make the sauce ahead of time?
A: Yes, you can prepare the sauce up to a day in advance. Store it in an airtight container in the refrigerator and reheat gently before adding the crabmeat and fish.

Q: How do I know when the rockfish is cooked through?
A: The fish is done when it flakes easily with a fork and the internal temperature reaches 145°F (63°C).

Q: Can I grill the rockfish instead of pan-frying it?
A: Absolutely! Grilling adds a lovely smoky flavor. Just make sure to oil the grill grates well to prevent sticking, and cook the fish for about 3-4 minutes per side.
