Walnut-Crusted Salmon
with a Roasted Veggie Jumble & Lemon Crème Fraîche
- Tree Nuts
- Milk
- Wheat
- Fish
Is there anything better than tender, buttery fish with a crunchy, nutty topping? Why, yes! How about salmon fillets coated in tangy Dijon mustard, then crusted in a mixture of chopped walnuts, panko, and butter? (To be honest, we’d eat anything with that sprinkled on top!) The topping turns toasty and crispy in the oven as the fish cooks to juicy perfection. As if that weren’t enough to sell you, it’s roasted alongside veggies in just one sheet pan. Easy, breezy weeknight dinner never tasted so good.

Cooking Steps
• Adjust rack to top position (top and middle positions for 4 servings) and preheat oven to 425 degrees. Wash and dry all produce. • Dice potatoes into ½-inch pieces (peel first if desired). Finely chop walnuts. Trim and quarter zucchini lengthwise; slice crosswise into ½-inch-thick pieces. Halve, peel, and dice onion. Zest and quarter lemon. • Place 2 TBSP butter (3 TBSP for 4) in a medium microwave-safe bowl. Microwave until melted, 30 seconds. Let cool slightly, then stir in walnuts, panko, and a pinch of salt and pepper.
• Toss potatoes on one side of a baking sheet with a drizzle of oil, a big pinch of Italian Seasoning (you’ll use more in the next step), salt, and pepper. • Roast on top rack for 8-10 minutes (you’ll add more to the sheet then).
• Meanwhile, pat salmon* dry with paper towels. Season with half the remaining Italian Seasoning (you’ll use more in the next step), salt, and pepper. • Brush flesh sides with mustard, then mound with walnut mixture, pressing firmly to adhere (no need to coat the undersides).
• Once potatoes have roasted 8-10 minutes, remove sheet from oven. (For 4 servings, leave potatoes roasting; add zucchini, onion, and salmon to a second baking sheet and roast on middle rack.) • Carefully add zucchini and onion to empty side; drizzle with oil. Season with a pinch of remaining Italian Seasoning (use the rest as you like), salt, and pepper. Toss to combine. Nestle salmon skin sides down into veggies. • Roast on top rack until salmon is cooked through, walnut crust is toasted, and veggies and potatoes are tender, 10-15 minutes. TIP: If veggies or potatoes finish before salmon, transfer to a medium bowl and continue roasting salmon.
• Meanwhile, place 1 TBSP butter (2 TBSP for 4 servings) in a small microwave-safe bowl; microwave until melted, 30 seconds. Stir in crème fraîche, half the lemon zest, and juice from 2 lemon wedges (4 wedges for 4). Season lightly with salt.
• Remove salmon from sheet. Stir together veggies and potatoes. • Divide everything between plates. Top salmon with lemon crème fraîche and remaining lemon zest to taste. Serve with remaining lemon wedges on the side.

Reviews from our home cooks
Nice, thick filets were delicious and perfectly done in the time indicated. The walnut crumb topping was very good. Veggies were fresh and good quality. The potatoes were not done in the cooking time - maybe our pieces were larger - but it was easy to finish them in the microwave. The lemon creme fraiche was fabulous - could eat it with a spoon - but salmon is so rich and oily that the combination had too much fat for my taste.
The walnut crusted salmon with Lemon Crème Fraîche is absolutely one of the best entrees I've made from Hello Fresh (over a span of several years). Nothing too extraordinary about the sides, though they too were quite good and very plentiful.
The taste was stellar and we had SO many veggies. The only comment is that the prep was quite involved for a one sheet pan recipe. Outstanding flavors though and can't wait to do the walnut/panko crust again in the future.
The salmon was amazing and voted unanimous at our house as the best salmon so far because of that knock out panko/chopped walnut/butter crispy goodness baked on top of the salmon. We roasted the potatoes in the Air Fryer on the roast setting and I pan cooked the zucchini. I did that for 2 reasons - one it was faster and we had a softball game to get to, and two because we didn't want to turn on the oven (warm day). Very good and would certainly recommend it and will order again or make at home.
We felt like for "walnut-crusted salmon", the flavor of the walnuts was a bit too subtle. Also, the potatoes took a LOT longer to cook than the recipe claimed. The lemon sauce was a little too lemony. However, we liked the idea of the recipe, so after following the recipe for the first two servings, we made some modifications (longer cook time for potatoes, less lemon juice in the sauce, pre-toasting the walnuts) that made it better to our tastes.
This is a scrumptious meal my family enjoyed! The balance of the tangy, lemony cream fraiche really complements the rich and savory taste of the salmon! The roasted veggie jumble is bursting with flavors!
This was absolutely the best salmon recipe ever! I'd like to give this 5 stars! The mustard, panko and walnut crust kept the moisture in the fish and it cooked perfectly and just melted in my mouth. I'll hope to order it again! Yummy!
I liked this a lot more than I thought I would. The salmon came out perfectly moist and tender. I wouldn't recommend eating the skin as it didn't crisp up at all but it made it easier to transfer the salmon from the sheet pan to the plate. The crust was tasty and the veggies came out well.
This is one of our new favorites. The walnut and panko topping on the salmon really elevated this dinner. I had never had creme fraiche. I love how HelloFresh gets me trying new things.
I love salmon; the walnut crust was delicious but it was hard to taste the dijon mustard. Yukon potatoes are quite tasty. I also liked the "one pan approach." It was so easy to prepare.
