Barefoot Contessa’s Roasted Fish in a Mustard Sauce: A Weeknight Wonder

There are certain dishes that, with just a few ingredients and a whisper of effort, transport you. For me, this Barefoot Contessa creation is precisely one of those. I remember the first time I made it; it was a blustery Tuesday evening, the kind where takeout feels like the only option. But there, nestled on the counter, were a few beautiful red snapper fillets. A quick glance at the ingredients list – creme fraiche, a couple of mustards, shallots, capers – and a spark of inspiration ignited. The simplicity was disarming, yet the resulting flavors were anything but. The aroma that filled my kitchen as the fish roasted, mingling with the bright tang of mustard and the subtle sweetness of shallots, was pure comfort. It’s become a go-to for those nights when deliciousness shouldn’t be a production, proving that elegant flavors are often just a few steps away.

Recipe Overview

• Prep Time: 10 minutes
• Cook Time: 10-15 minutes
• Total Time: 20-25 minutes
• Servings: 4
• Yield: 4 fish fillets
• Dietary Type: Gluten-Free, Dairy-Free (with substitutions)

Ingredients

This recipe celebrates the beauty of simplicity, relying on a handful of quality ingredients to create a truly memorable dish.

• 4 (8-ounce) fish fillets, such as red snapper (or other firm, white-fleshed fish like cod, halibut, or sea bass)
• Kosher salt and freshly ground black pepper
• 8 ounces creme fraiche (found in the dairy section; see Variations for dairy-free option)
• 3 tablespoons Dijon mustard
• 1 tablespoon whole grain mustard
• 2 tablespoons shallots, minced
• 2 teaspoons capers, drained
• 1 teaspoon kosher salt (for the sauce)
• 1/2 teaspoon fresh ground black pepper (for the sauce)

Equipment Needed

To bring this delightful dish to life, you’ll need a few essential kitchen tools:

• Baking sheet with sides (or an ovenproof baking dish large enough to hold the fish without crowding)
• Parchment paper (for lining the baking sheet)
• Small mixing bowl
• Whisk or fork
• Measuring spoons and cups

Instructions

The magic of this recipe lies in its straightforward execution. Follow these steps for a perfectly roasted fish, bathed in a luscious mustard sauce.

1. Preheat the Oven: Begin by preheating your oven to 425 degrees F (220 degrees C). This high heat is crucial for quickly cooking the fish and developing a beautiful exterior.
2. Prepare Your Baking Sheet: Line a baking sheet with sides with parchment paper. If you don’t have a baking sheet with sides, an ovenproof baking dish will work just as well. The key is to ensure the dish or pan is large enough so the fish fillets are not crowded. Overcrowding can lead to steaming rather than roasting, which will affect the texture and cooking time.
3. Season the Fish: Place the fish fillets, skin side down, onto the prepared baking sheet or dish. Generously season them on all sides with kosher salt and freshly ground black pepper. Don’t be shy with the seasoning; it’s essential for bringing out the natural flavors of the fish.
4. Create the Mustard Sauce: In a small bowl, combine the creme fraiche, Dijon mustard, whole grain mustard, minced shallots, drained capers, 1 teaspoon of kosher salt, and 1/2 teaspoon of fresh ground black pepper. Mix these ingredients together thoroughly until well combined and smooth. The capers will add little bursts of briny flavor, while the shallots offer a delicate sweetness.
5. Sauce the Fish: Spoon the prepared mustard sauce evenly over each fish fillet. Ensure that the entire surface of the fish is generously covered with the sauce. This will not only add incredible flavor but also help keep the fish moist during cooking.
6. Roast to Perfection: Place the baking sheet or dish into the preheated oven. Bake for 10 to 15 minutes. The exact cooking time will depend on the thickness of your fish fillets. To check for doneness, gently insert a fork into the thickest part of the fish. It should flake easily and be opaque throughout. It’s paramount to avoid overcooking the fish, as this will result in a dry, less enjoyable texture. The high heat and relatively short cooking time are designed to cook the fish through without drying it out.
7. Serve Immediately: Once the fish is perfectly cooked, remove it from the oven. Serve the fish fillets immediately, spooning any extra sauce from the pan over the top. This dish is best enjoyed fresh from the oven.

Expert Tips & Tricks

Elevate your Barefoot Contessa experience with these chef-inspired insights:

• Fish Selection: While red snapper is called for, feel free to experiment with other firm white fish. The key is a fillet that can hold its shape and won’t fall apart too easily. Halibut, cod, and sea bass are excellent alternatives.
• Caper Power: If you’re not a fan of capers, you can omit them, but they truly add a wonderful dimension. A finely minced cornichon could be a daring substitute, offering a similar piquant note.
• Sauce Consistency: If your creme fraiche is particularly thick, you can whisk in a tiny splash of milk or water to achieve a slightly looser sauce consistency before spooning it over the fish.
• Doneness Test: Beyond the fork test, you can use an instant-read thermometer. The fish is done when it reaches an internal temperature of 145 degrees F (63 degrees C) at its thickest part.
• Crispy Skin: If you’re using fish with skin on and prefer it crispy, you can sear the skin side in a hot, oiled skillet for a minute or two before placing it in the baking dish and topping with the sauce. Then proceed with the oven step.

Serving & Storage Suggestions

This Roasted Fish in a Mustard Sauce is a star on its own, but it pairs beautifully with a variety of sides.

Serving:
Serve this dish piping hot, straight from the oven. It’s wonderful with simple steamed green beans, a light and crisp arugula salad with a lemon vinaigrette, or some fluffy rice pilaf to soak up any extra sauce. A crusty baguette is also perfect for sopping up every last bit of that delightful mustard sauce.

Storage:
Leftovers, if you’re lucky enough to have any, can be stored in an airtight container in the refrigerator for up to 2 days. While fish is best enjoyed fresh, reheating is possible. Gently reheat in a low oven (around 300 degrees F / 150 degrees C) for about 5-10 minutes, or until warmed through. Be cautious not to overcook during reheating. It’s not recommended to freeze this dish, as the texture of the fish may suffer.

Variations & Substitutions

• Dairy-Free Delight: For a dairy-free version, substitute the creme fraiche with a high-quality, unsweetened coconut cream or a cashew cream. Ensure the cream is thick and rich for the best sauce consistency.
• Herbaceous Notes: Stir in a tablespoon of finely chopped fresh dill, parsley, or chives into the sauce just before spooning it over the fish for an extra layer of freshness.
• Spicy Kick: Add a pinch of red pepper flakes to the sauce for a subtle hint of heat that beautifully complements the mustard.
• Lemon Zest Brightness: A teaspoon of finely grated lemon zest added to the sauce can provide a lovely citrusy lift, cutting through the richness of the creme fraiche.

FAQs

Q: What kind of fish is best for this recipe?
A: This recipe works wonderfully with firm, white-fleshed fish like red snapper, cod, halibut, or sea bass. The key is a fillet that holds its shape.

Q: Can I prepare the sauce ahead of time?
A: Yes, you can prepare the sauce a few hours in advance and store it in the refrigerator. Whisk it well before spooning it over the fish.

Q: My fish is very thin. How will that affect the cooking time?
A: If your fish fillets are thinner, they will cook more quickly. Start checking for doneness at the lower end of the cooking time, around 10 minutes, and adjust as needed.

Q: What if I don’t have shallots?
A: Finely minced red onion or garlic can be used as a substitute for shallots, though the flavor will be slightly different. Use about half the amount of garlic as it’s more potent.

Q: Is it okay to use dried capers?
A: It is best to use drained jarred capers. Dried capers would require rehydrating and would alter the texture and flavor profile significantly.
