Ingredients You’ll Need
The magic of this dish lies in its straightforward yet thoughtfully chosen ingredients. Each one adds a unique element, from the nutty depth of walnuts to the herbal brightness of fresh basil, harmonizing perfectly to create that irresistible crust.
- 4 (6 oz) Chilean seabass fillets: Choose fresh, thick fillets for the best buttery, melt-in-your-mouth texture.
- 1/2 cup raw walnuts: These provide a rich, earthy base for the pesto crust with a satisfying crunch.
- 1 cup fresh basil leaves: Basil brings lovely herbaceous notes and vibrant color to the pesto.
- 2 tablespoons grated Parmesan cheese: Adds umami depth and a subtle saltiness that enhances the overall flavor.
- 2 cloves garlic: Fresh garlic infuses the pesto with a fragrant, savory punch.
- 1/4 cup olive oil: Helps bind the pesto ingredients while lending a fruity richness.
- 1 tablespoon lemon juice: Brings bright acidity that wakes up the flavors and balances the richness.
- Salt and pepper to taste: Essential for seasoning and enhancing all the other ingredients.
- 1 tablespoon avocado oil or olive oil (for searing): This high-heat oil ensures a perfect golden crust on the seabass without burning.
- Lemon wedges for serving: A fresh squeeze just before eating gives a lively finish.
How to Make Keto Chilean Seabass with Walnut Pesto Crust Recipe
Step 1: Prepare the Walnut Pesto
Start by creating that indulgently flavorful walnut pesto crust. Combine the raw walnuts, fresh basil leaves, grated Parmesan, garlic cloves, olive oil, lemon juice, salt, and pepper in a food processor. Pulse until the mixture forms a thick, slightly coarse pesto – you want it to hold together well for the crust but still have some texture.
Step 2: Season and Sear the Seabass
Pat your Chilean seabass fillets dry with paper towels to ensure a nice sear. Season each fillet generously with salt and pepper. Heat your skillet with avocado or olive oil over medium-high heat. Place the fillets skin-side down (or the presentation side, if skinless) and sear for 2 to 3 minutes until you achieve a beautiful golden crust. Carefully flip and sear the other side for just 1 minute – you want the fish to be beautifully caramelized without fully cooking through yet.
Step 3: Top with Pesto and Bake
Remove the skillet from the heat and spoon a generous layer of your walnut pesto onto each seabass fillet. Spread it evenly to cover the top surface. Transfer the skillet to the preheated oven set at 400°F. Bake for 8 to 10 minutes until the fish flakes easily with a fork and the pesto crust is lightly toasted.
Step 4: Serve and Enjoy
Remove from the oven and let the fillets rest briefly. Serve each piece of seabass with a fresh lemon wedge to squeeze on top. Get ready for a sensory delight—crisp and nutty on the outside, tender and buttery inside, bursting with vibrant herbal notes.
How to Serve Keto Chilean Seabass with Walnut Pesto Crust Recipe
Garnishes
A simple garnish like fresh basil leaves or microgreens brings a pop of color and enhanced aroma that highlights the pesto’s herbal freshness. A light drizzle of extra virgin olive oil over the top adds an inviting sheen and a touch more lusciousness.
Side Dishes
This dish pairs wonderfully with typical keto-friendly sides such as creamy cauliflower mash or garlic sautéed spinach. Both complement the richness of the seabass while keeping the meal low-carb and nutrient-dense. Roasted asparagus or a crisp arugula salad with lemon vinaigrette are also fantastic choices to balance the meal.
Creative Ways to Present
For a stunning presentation, serve the fillets on a bed of mixed greens or colorful ratatouille to bring vibrancy to your plate. You can also drizzle a little extra walnut pesto around the plate for an artistic flair. Offering lemon wedges arranged attractively not only looks beautiful but invites diners to customize the acidity to their liking.
Make Ahead and Storage
Storing Leftovers
If you happen to have leftovers, store the seabass separately from the pesto crust in an airtight container in the refrigerator. This helps preserve the texture of the crust and keeps the fish fresh for up to two days.
Freezing
While the walnut pesto crust is delicious fresh, this dish doesn’t freeze well after baking due to the delicate texture of the seared fish. However, you can make and freeze the pesto on its own for up to a month. Just thaw it slowly in the fridge before using.
Reheating
Reheat leftovers gently in an oven set to low heat (around 300°F) to avoid drying out the fish. Place the fillets in an oven-safe dish, cover loosely with foil, and warm until heated through. Avoid microwaves as they can make the crust soggy and the fish tough.
FAQs
Can I use other nuts besides walnuts for the pesto crust?
Absolutely! While walnuts provide a rich, earthy flavor, almonds or pecans can work well too. Just keep in mind that the flavor and texture will vary slightly with different nuts.
Is Chilean seabass sustainable to eat?
Chilean seabass is a sensitive species under strict regulations. It’s best to check for sustainably sourced fish or consider alternatives like sablefish if sustainability is a concern for you.
How can I make this recipe dairy-free?
You can omit the Parmesan cheese or substitute it with nutritional yeast to maintain the savory depth without dairy. The pesto will still be deliciously flavorful.
Can I prepare the pesto crust in advance?
Yes! The walnut pesto crust can be made up to 5 days ahead and stored in the refrigerator. This makes weeknight cooking quicker and keeps the flavors vibrant.
What side dishes are best for keeping this meal keto-friendly?
Opt for low-carb vegetables like cauliflower, spinach, asparagus, or leafy salads. Avoid starchy sides like potatoes or grains to maintain the keto guidelines.
